Technical Field

The present invention relates to a transmission for motorcycles according to the preamble of claim 1. The invention also relates to a motorcycle with such a transmission according to the preamble of claim 10.

Background

Such a transmission for a motorcycle and a motorcycle having such a transmission are already known, for example, from CN 1699108A. The transmission has a housing and at least one shaft which is rotatable relative to the housing and is at least partially accommodated in the housing. The shaft is for example a transmission output shaft. In its completely manufactured state, the motorcycle comprises, for example, the transmission and a drive engine, which is designed, for example, as an internal combustion engine, by means of which at least one wheel of the motorcycle, and thus the motorcycle as a whole, can be driven via the transmission.

The transmission also includes a locking device having at least one locking element disposed in the housing. The locking element is movable relative to the housing between at least one locking position and at least one release position. In the locked position, the locking element locks the shaft against rotation relative to the housing so that the shaft cannot rotate relative to the housing. In the release position, the locking element releases the shaft for rotation relative to the housing so that the shaft can rotate relative to the housing. The axle is for example coupled at least indirectly with the aforementioned at least one wheel of the motorcycle, so that the wheel is locked against rotation when the axle is locked against rotation relative to the housing by means of the locking element. The at least one wheel cannot then be turned, so that the motorcycle cannot simply roll along a traffic lane, for example, and thus cannot be easily stolen.

Furthermore, DE 4235142 a1 discloses a motor cycle transmission lock, the task of which is to achieve good theft protection.

Disclosure of Invention

The object of the invention is to further develop a transmission and a motorcycle of the type mentioned at the outset such that a particularly simple operation is possible and at the same time an unintentional rolling away is particularly advantageously prevented.

According to the invention, said object is achieved by a transmission having the features of claim 1 and by a motorcycle having the features of claim 10. Advantageous embodiments with suitable further developments of the invention are given in the remaining claims.

A first aspect of the invention relates to a transmission for a motorcycle. Within the scope of the invention, a motorcycle is a single-track motor vehicle, also known as a motorbike. Motorcycles can be used, for example, alone (i.e. without sidecars) or together with sidecars, so that the motorcycle and the sidecar form a set. The transmission comprises a housing, also referred to as transmission housing, and at least one shaft which is rotatable relative to the housing and which is at least partially, in particular at least largely or completely, accommodated in the housing, for example rotatable relative to the housing about an axis of rotation. The shaft is, for example, a transmission output shaft of a transmission. Alternatively or additionally, the shaft may be at least indirectly coupled to at least one wheel of the motorcycle, so that, for example, in the completely manufactured state of the motorcycle, the at least one wheel can be driven by at least one drive engine of the motorcycle, for example, designed as an internal combustion engine, via a transmission, in particular via the shaft.

The transmission also includes a locking device having at least one locking element disposed in the housing. The locking element is movable relative to the housing and, for example, relative to the shaft between at least one locking position and at least one release position. The locking element locks the shaft against rotation about the rotation axis relative to the housing in the locked position, so that the shaft cannot rotate about the rotation axis relative to the housing in the locked position. However, in the release position the locking element releases the shaft for rotation relative to the housing, in particular about the rotation axis, so that in the release position the shaft can rotate relative to the housing about the rotation axis. Since the at least one wheel is coupled to the shaft, for example in the completely manufactured state of the motorcycle, wherein the wheel can be held at least indirectly on the frame of the motorcycle and can be rotated relative to the frame about the wheel rotation axis, for example in the completely manufactured state of the motorcycle, the wheel is locked against rotation relative to the frame, in particular about the wheel rotation axis, for example in the locking position of the locking element. This means that the wheel cannot be rotated in the locked position of the locking element, since such a wheel rotation is prevented via the shaft by means of the locking element. Thus, for example, the motorcycle cannot easily roll away and in particular cannot easily roll away in an undesired manner along a traffic lane, so that a particularly advantageous protection of the motorcycle against undesired rolling away can be achieved. In the release position, however, the wheel can be rotated relative to the frame, in particular about the wheel rotation axis, since the shaft can be rotated relative to the housing about its rotation axis.

In order to now be able to achieve a particularly advantageous manoeuvrability of the motorcycle and to protect the motorcycle particularly advantageously against undesired rolling away, according to the invention at least one operating element is provided which is arranged at least partially outside the housing, i.e. in the surroundings of the housing, can be manually operated by a person from outside the housing, i.e. from the surroundings of the housing, and can thus be moved relative to the housing. The locking element can be moved between a release position and a locking position by means of an actuating element which is moved relative to the housing. In other words, the locking element can be moved relative to the housing between the release position and the locking position by manually moving the operating element relative to the housing from outside the housing. In this way, the locking element can be moved from outside the housing by a person in a simple and comfortable manner via the operating element between the release position and the locking position.

Furthermore, according to the invention, a locking device is provided which can be switched between at least one locked state in which the actuating element is locked against movement relative to the housing and at least one unlocked state in which the actuating element is released from movement relative to the housing. In other words, in the locked state, the operating element is locked against movement relative to the housing by means of the locking device, so that the operating element and thus the locking element cannot move relative to the housing. If, for example, the locking element is thus in its locking position and if the locking device is in its locking state during this time, the locking element cannot be moved in an undesired manner from the locking position into the release position, so that particularly good protection against undesired rolling away and thus, for example, particularly good theft protection can be achieved.

In the unlocked state, however, the locking device releases the movement of the operating element relative to the housing, so that in the unlocked state of the locking device the operating element can be moved relative to the housing. The locking element can thus be moved relative to the housing via the operating element and can thus be moved, for example, from the locking position to the release position or vice versa.

In order to be able to switch the locking device between the locked state and the unlocked state in a particularly simple and comfortable manner and thus to be able to operate the transmission and thus the entire motorcycle in a particularly simple and comfortable manner, it is furthermore provided that the locking device has at least one receiving unit which is designed to receive at least one signal provided by the remote control device on the basis of radio, i.e. without cable and thus without wires, and to cause the locking device to switch from the locked state to the unlocked state as a function of the received signal. The switching of the locking device from the locked state to the unlocked state is also referred to as unlocking of the locking device. The locking device can thus be at least unlocked and preferably locked, i.e. switched from the unlocked state to the locked state, by means of the remote control device, so that a person, for example the aforementioned person who wants to move the locking element from the locked position to the release position and thus moves the operating element, can unlock the locking device in a particularly simple and comfortable manner.

In order to achieve a particularly simple and comfortable handling of the motorcycle, it has proven advantageous if the receiving unit is designed to detect that the distance between the person and the actuating element is below a predefinable threshold value, in particular that the person touches the actuating element. The receiving unit is also designed to switch the locking device from the locked state to the unlocked state as a function of detecting that the distance between the person and the operating element is below a predefinable threshold value, in particular that the person touches the operating element. In this way, for example, a person can unlock the locking device in a particularly simple manner, so that the person can easily carry the remote control with him, for example in a pocket of clothing, and the person can approach the operating element, in particular touch it, for example with at least one body part, in particular without the person having to actuate the remote control. In particular, a threshold value below is understood to mean that the locking device has been unlocked or can be unlocked, for example, in such a way that the distance between the person and the operating element is below a predefinable threshold value, without the person touching the operating element. For example, the person can already unlock the locking device by approaching the operating element, in particular with at least one body part, without however touching the operating element. In addition, a falling below the threshold value means that the person unlocks or can unlock the locking device in such a way that the person touches or has to touch the operating element with at least one body part. The body part is for example a hand or a finger. Thus, if, for example, the distance between the operating element and the finger is below a threshold value or the finger touches the operating element, the blocking device is unlocked when the receiving unit receives a signal provided by the remote control.

In summary, it can be seen that the reception of the signal by the receiving unit and the detection of a distance below a threshold value or the contact of a person with the operating element are two criteria which must be met at least or exclusively for the purpose of switching the locking device from the locked state to the unlocked state. In other words, the locking device is unlocked or the receiving unit unlocks the locking device or causes the locking device to unlock if both criteria are fulfilled, in particular simultaneously or consecutively, within a predeterminable time period.

The receiving unit here comprises, for example, at least one receiving element and at least one evaluation element. By means of the receiving element, for example, a signal can be received. Furthermore, for example, by means of the receiving element, it can be detected that the distance is below a threshold value or that a person touches the operating element. For example, the receiving element provides at least one or more, in particular electrical, data characterizing the respective above-mentioned criterion, which data is received, for example, by the evaluation element. The evaluation component can analyze the evaluation data and thus determine, for example, whether a criterion is fulfilled. If the evaluation unit determines that both criteria, in particular simultaneously or within a predeterminable time period, are fulfilled, the receiving unit, in particular serving as a receiving and evaluation unit, causes the locking device to be switched from the locking position into the release position. In this way, the locking device can be unlocked without the remote control device interacting mechanically with the motorcycle or being inserted into a corresponding recess of the motorcycle. In order to unlock the locking device, it is merely sufficient if the receiving unit receives a signal provided by the remote control and the person approaches the operating element with at least one body part, for example his hand, in such a way that the distance between the person and the operating element is below a threshold value, in particular if the person touches the operating element. This makes it possible to operate the motorcycle particularly easily and comfortably. After unlocking of the locking device, the operating element, which is designed as a lever, for example, can be moved manually by a person, in order to be able to adjust or move the locking element as required.

The remote control is, for example, a so-called key, with which, for example, the locking device can be unlocked and preferably locked. The key can have a key bit which can be inserted, for example, into a corresponding recess of the motorcycle in order to thereby start the drive engine and/or unlock and/or lock the motorcycle, for example, by mechanical interaction of the key with the motorcycle, in particular when, for example, the remote control cannot provide the mentioned signal or unlock the motorcycle wirelessly, in particular on a radio basis. This is the case in particular when no electrical energy is stored in the energy source of the remote control, which source is designed, for example, as a battery, by means of which signals can be provided.

In order to be able to operate the transmission and thus the entire motorcycle, or both, in a particularly simple manner, in a further embodiment of the invention it is provided that the blocking device is held at least indirectly, in particular directly, on the housing independently of the operating element.

Furthermore, it has proven to be particularly advantageous if the locking device is held at least indirectly, in particular directly, on the actuating element in a manner independent of the housing. Particularly advantageous operation or operability can thereby also be achieved.

The blocking device is, for example, a module which can be produced separately from the transmission and which can therefore be mounted on the transmission or on the lever in a preassembled manner. In order to be able to achieve the desired function of the locking device, such as the described unlocking, the module has corresponding dimensions, i.e. corresponding external dimensions. It has been found that the modules cannot be arranged without problems, for example, in the tank area or on the fork bridge of a motorcycle, since this may impair other functions and/or visual impressions of the motorcycle. In this case, it has proven to be particularly advantageous if the module is held on the housing and thus on the transmission or on an actuating element, which is embodied, for example, as a lever. This allows a particularly advantageous and visually satisfactory arrangement of the locking device or the module in terms of installation space.

A further embodiment is characterized in that the operating element is pivotable relative to the housing about a pivot axis for moving the locking element between the release position and the locking position. A particularly advantageous operation is thereby possible, since the locking element can be moved via the operating element with only a small force consumption.

In a further embodiment of the invention, the operating element is permanently coupled to the locking element in such a way that a movement of the operating element relative to the housing and a movement of the locking element between the locking position and the release position occur simultaneously. In this way, the locking element can be moved easily and comfortably.

A further embodiment is characterized in that the locking element has at least one locking wheel which is connected to the shaft in a rotationally fixed manner and which is also referred to as locking wheel and can be moved back and forth in the axial direction of the shaft relative to the shaft between a locking position and a release position. In this way, an especially effective prevention of undesired rolling away or rolling away can be achieved in a space-saving manner.

In order to be able to prevent the at least one wheel and thus the entire motorcycle from undesirably rolling away particularly effectively, in a further embodiment of the invention the locking wheel interacts at least indirectly, in particular directly, with the housing in the locked position.

In this case, it has proven to be particularly advantageous if the locking wheel engages directly into the housing in the locked position and thereby interacts directly with the housing in a form-fitting manner. This enables a particularly advantageous force flow, so that the motorcycle can also be prevented from rolling away undesirably for high forces or torques.

A second aspect of the invention relates to a motorcycle comprising at least one drive engine, for example, designed as an internal combustion engine or as an electric motor, by means of which at least one wheel of the motorcycle and thus the entire motorcycle can be driven. The motorcycle further comprises a transmission, in particular according to the invention, which can be driven by the drive engine. The at least one wheel can be driven by a drive engine via a transmission, for example. The transmission has a housing and at least one shaft which is rotatable relative to the housing and is at least partially accommodated in the housing. Furthermore, the motorcycle, in particular the transmission, comprises a locking device having at least one locking element arranged in the housing. The locking element is movable relative to the housing between at least one locking position in which the locking element locks the shaft against rotation relative to the housing and at least one release position in which the locking element releases the shaft for rotation relative to the housing.

In order to now be able to achieve a particularly advantageous operation or handling of the motorcycle and to be able to prevent the motorcycle from rolling away, particularly advantageously, according to the invention at least one operating element is provided which is arranged at least partially outside the housing and can be manually actuated by a person from outside the housing and can thus be moved relative to the housing, by means of which operating element the movement of the operating element can cause the locking element to move between the release position and the locking position. Furthermore, according to the invention, a locking device is provided which can be switched between at least one locked state in which the actuating element is locked against movement relative to the housing and at least one unlocked state in which the actuating element is released from movement relative to the housing.

The locking device has at least one receiving unit, which is designed to receive at least one signal provided by the remote control on a radio basis and thus without cable or wire and to switch the locking device from the locked state to the unlocked state as a function of the received signal. The advantages and advantageous embodiments of the first aspect of the invention can be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

As already described above with respect to the operating element for the first aspect of the invention, it is preferably provided in an advantageous embodiment of the second aspect of the invention that the receiving unit is designed to detect: the distance between the person and at least one component of the motorcycle is below a predefinable threshold, in particular the person touching the component. In this case, the receiving unit is preferably designed to switch the locking device from the locked state to the unlocked state as a function of the detection. The component is, for example, the operating element described above or a structural element of the motorcycle which is different from the operating element and is provided in addition to the operating element. If, for example, the receiving unit detects that a person approaches the component, in particular with at least one body part, for example a hand, such that the distance between the component and the person is below a threshold value, in particular that the person touches the component, and if the receiving unit receives a signal, in particular an electrical signal, preferably an electromagnetic signal, which is provided by the remote control, the receiving unit causes the locking device to switch from the locked state to the unlocked state. The above and the following description of the operating elements can therefore also be transferred without problems to the components described and vice versa. In a particularly simple and comfortable manner, the person can thus unlock the locking device simply by the receiving unit receiving the signal provided by the remote control and the person approaching the component in such a way that the distance between the person and the component is below a threshold value, in particular by the person touching the component. Here, for example, the person simply carries the remote control with him, for example in a pocket of a garment. Thus, the person can unlock or unlatch the latching device without the remote control mechanically interacting with or contacting the motorcycle.

An undesired unlocking of the locking device can be avoided in that, in order to unlock the locking device, not only the criterion that the receiving unit receives a signal provided by the remote control device is fulfilled, but additionally at least the criterion that the distance between the person and the component is below a threshold value must also be fulfilled. In other words, in order to unlock the locking device, at least the aforementioned criteria must be met. Thus, the person can move the operating element and thus the locking element in a simple and comfortable manner.

Drawings

Further details of the invention emerge from the following description of preferred embodiments and from the accompanying drawings. Here:

figure 1 shows a schematic side view of a motorcycle according to the invention; and

fig. 2 shows a schematic cut-away side view of a transmission according to the invention of a motorcycle.

Detailed Description

In the figures, identical or functionally identical elements are provided with the same reference signs.

Fig. 1 shows a motorcycle 1, which is a single-track motor vehicle and is also referred to as a motorbike, in a schematic side view. The motorcycle 1 comprises at least or preferably exactly two wheels 2 and 3, which are arranged one after the other in the longitudinal direction of the motorcycle 1 and which are associated with one and the same rut. Furthermore, the motorcycle 1 comprises a frame 4, which is shown particularly schematically in fig. 1, on which the wheels 2 and 3 are each held at least indirectly rotatably. The motorcycle 1 here also comprises a rocker arm 5 which is pivotably held on the frame 4 and is supported on the frame 4 with elastic damping and damping. The wheel 3 is held in a rotatable manner on a rocker 5 and via this on the frame 4. Furthermore, the motorcycle 1 comprises a fork 6, which is configured for example as a shock absorbing fork, which can be pivotably held on the frame 4 and can thus be pivoted relative to the frame 4 about a pivot axis, also referred to as steering axis. The wheel 2 is rotatably held on the fork 6. If the fork 6 is pivoted about the steering axis relative to the frame 4, the wheel 2 and thus the motorcycle 1 as a whole are steered, whereby, for example, a change of direction or a cornering of the motorcycle 1 can be caused.

As can be seen from fig. 1, the wheel 2 is the front wheel of the motorcycle 1, while the wheel 3 is the rear wheel. The motorcycle 1 can be supported in the vertical direction via the wheels 2 and 3 on the traffic lane 7 and can be driven along the traffic lane via the wheels 2 and 3. While traveling along the traffic lane, the wheels 2 and 3 roll on the traffic lane 7.

The motorcycle 1 comprises a drive train 8 which is held at least indirectly on the frame 4 or is connected to the frame 4 and by means of which, for example, the wheels 3 and thus the motorcycle 1 as a whole can be driven. The drive train 8 comprises, for example, a drive engine 9, which is in particular designed as an internal combustion engine, and a transmission 10, via which the wheels 3 and thus the motorcycle 1 as a whole can be driven by the drive engine 9. The transmission 10 is illustrated in a schematic and sectional side view in fig. 2. As can be seen from fig. 2, the transmission 10 has a housing 11, also referred to as a transmission housing, by means of which a receiving space 12 is delimited or formed, for example, at least in part, in particular at least in large part or completely. The housing 11 comprises, for example, at least two housing elements which are formed separately from one another and are connected to one another.

The transmission 10 further comprises a first shaft, which is designed as a transmission input shaft 13 and is rotatably mounted on the housing 11 and is thus rotatable relative to the housing 11 about a first axis of rotation 14. The transmission input shaft 13 can be driven, for example, by the drive engine 9, in particular by an output shaft of the drive engine 9, which output shaft is designed as a crankshaft, so that, for example, a torque provided by the drive engine 9 via the output shaft can be transmitted from this output shaft to the transmission input shaft 13. The torque provided by the drive engine 9 via the output shaft can be introduced into the transmission 10 via the transmission input shaft 13, so that the transmission 10 is or can be driven by the drive engine 9 via its output shaft.

The transmission 10 also includes a second shaft in the form of a transmission output shaft 15 that is rotatably supported on the housing 11. The transmission output shaft 15 is thus in principle rotatable about the second axis of rotation 16 relative to the housing 11. The axes of rotation 14 and 16 extend here, for example, at least substantially parallel to one another and are spaced apart from one another, i.e. are axially spaced apart from one another. The transmission output shaft 15 is coupled, for example, at least indirectly to the wheels 3, wherein the transmission output shaft 15 is in particular permanently coupled to the wheels 3. Thus, if the transmission output shaft 15 rotates about the second rotation axis 16 relative to the housing 11, the wheels 3 thereby rotate relative to the frame 4. Conversely, if, for example, the wheel 3 is rotated relative to the frame 4, in particular by the motorcycle 1 rolling along the traffic lane 7 in a state supported on the traffic lane 7 via the wheels 2 and 3, the transmission output shaft 15 is thereby rotated relative to the housing 11 about the rotation axis 16, which is possible in particular when the transmission output shaft 15 is released to rotate relative to the housing 11 about the rotation axis 16.

The shafts are coupled or couplable, in particular torque-transmitting, to one another, for example via a respective gear 17 arranged on the respective shaft. In other words, torque can be transmitted between the shafts via, for example, mutually meshing gears 17 of the transmission 10, so that, for example, the wheels 3 can be driven by the output shaft of the drive engine 9 and thus by the drive engine 9 via the transmission output shaft 15, the respective gear 17 and the transmission input shaft 13.

As can be seen particularly well in fig. 2, the transmission 10 has a locking device 18 which comprises at least one locking element 19 arranged in a housing. The locking element 19 can be moved, in particular in a translatory manner, relative to the housing 11 and relative to the shafts between at least one locking position shown in fig. 2 and at least one release position not shown in the figures. In the locked position, the transmission output shaft 15 is locked against rotation about the axis of rotation 16 relative to the housing 11 by means of the locking element 19, so that the transmission output shaft 15 cannot rotate about the axis of rotation 16 relative to the housing 11. Thus, the wheel 3 does not rotate relative to the frame 4. Thereby, for example, the motorcycle 1 is prevented from undesirably rolling or rolling along the traffic lane 7. However, in the release position, the locking element 19 releases the transmission output shaft 15 for rotation relative to the housing 11 about the rotational axis 16, so that the transmission output shaft 15 can rotate relative to the housing 11 about the rotational axis 16 and the wheel 3 rotates relative to the frame 4.

Now, in order to be able to achieve a particularly advantageous operation or manoeuvrability of the motorcycle 1 and to prevent the motorcycle from rolling away undesirably, the motorcycle 1, in particular the transmission 10, comprises at least one operating element in the form of a lever 21 which is arranged at least partially outside the housing 11 and thus in the surroundings 20 of the housing, which is manually operable by a person from outside the housing 10 and thus from the surroundings 20, and which is thus movable relative to the housing 11. The lever 21 is for example arranged on or beside a side 22 of the housing 11, wherein the side 22 is directed outwards in the transverse direction of the motorcycle 1. The lever 21 can thus be easily and comfortably manipulated by the person from the side 22 and thus moved relative to the housing 11. By means of the lever 21, the movement of the locking element 19 between the release position and the locking position can be achieved by a movement of the lever 21 relative to the housing 11.

Furthermore, the motorcycle 1, in particular the transmission 10, comprises a locking device 23, which is shown in particular schematically in fig. 1 and is in particular designed as a module or module part, which can be switched between at least one locked state, in which the lever 21 is locked against movement relative to the housing 11, and at least one unlocked state, in which the lever 21 is released from movement relative to the housing 11. As can be seen from fig. 1, the locking device 23 comprises a receiving unit 24, which is shown in particular schematically in fig. 1 and serves as a receiving and evaluation unit, which is designed to receive at least one, in particular electrical, signal 25, which is provided by a remote control 26, which is shown in particular schematically in fig. 1, on the basis of radio and thus without cable or wire, and is preferably electromagnetic, and to switch the locking device 23 from the locked state to the unlocked state as a function of the received signal 25.

Furthermore, the receiving unit 24 is configured to detect: the distance between the person and a component of the motorcycle 1, such as the lever 21, is below a predefinable threshold, in particular the person touching the lever 21. Furthermore, the receiving unit 24 is designed to cause the locking device 23 to switch from the locked state to the unlocked state as a function of detecting that the distance between the person and the lever 21 falls below a predefinable threshold value. This means that the locking device 23 can be unlocked or unlocked if and only if the receiving unit 24 receives the signal 25 and detects that the distance between the person and the lever 21 is below a predefinable threshold value, in particular if the person touches the lever 21. The lever 21 is a component of the motorcycle 1, wherein the above and the following explanations of the lever 21 with respect to the detection of a distance between the person and the lever 21 below a predefinable threshold value, for example, can also be transferred without problems to at least one other component of the motorcycle 1 than the lever 21 which is attached to this arrangement.

In summary, it can be seen that the person can unlock the locking device 23 in a particularly simple and comfortable manner by: the person carries a remote control 26, for example, with him, so that the receiving unit 24 can receive the signal 25 and the person approaches the component, which is currently in the form of the lever 21, in such a way that the person touches the component or the distance between the person and the component falls below a threshold value. The remote control 26 provides the signal 25 permanently and/or independently of the manipulation or operation of the remote control 26 by the person. In this way, the person can switch the locking device 23 from the locked state into the unlocked position and thus unlock the device, without the remote control device 26 touching the motorcycle 1 or mechanically interacting with the motorcycle 1 and without the person actuating the remote control device 26.

The locking device 23 is held in this case at least indirectly, in particular directly, on the housing 11 independently of the lever 21, or the locking device 23 is held in this case at least indirectly, in particular directly, on an operating element in the form of the lever 21 independently of the housing 11. The locking device 23 can thus be designed to be particularly space-saving and visually attractive, so that in particular a particularly advantageous visual impression of the motorcycle 1 as a whole can be achieved.

As can be seen from fig. 1 and 2 and indicated by the double-headed arrow 27, the lever 21 can be pivoted about a pivot axis 28 relative to the housing 11 for moving the locking element 19 between the release position and the locking position. Furthermore, the lever 21 is permanently coupled with the locking element 19, so that a movement of the lever 21 relative to the housing 11 and a movement of the locking element 19 between the locking position and the release position occur simultaneously. The locking element 19 has at least one locking wheel 29, which is connected in a rotationally fixed manner to the transmission output shaft 15 and which, as is indicated in fig. 2 by a double arrow 30, can be moved back and forth in the axial direction of the transmission output shaft 15 and thus along the axis of rotation 16 relative to the transmission output shaft 15 and thus between a locking position and a release position.

The locking wheel 29 has a recess 31 in which the lever 21 engages, in particular via a finger 32 of the lever 21. The lever 21 is thereby permanently positively connected to the locking wheel 29, so that the locking wheel 29 can be moved back and forth in the axial direction of the transmission output shaft 15 relative to the latter between a locking position and a release position by pivoting, in particular back and forth pivoting, the lever 21 about the pivot axis 28 relative to the housing 11.

Furthermore, as can be seen particularly well in fig. 2: the locking wheel 29 interacts directly with the housing 11 in a form-locking manner in the locked position in that the locking wheel 29, in particular the respective fingers 33 of the locking wheel 29, engage in the respective recesses 34 of the housing 11. The recess 34 can be formed by an element fixed in the housing 11, i.e. for example by an element which is formed separately from the housing 11 and is fixed in the latter. Thereby, the locking wheel 29 is locked against rotation about the rotation axis 16 relative to the housing 11. Since the locking wheel 29 is connected in a rotationally fixed manner to the transmission output shaft 15, the transmission output shaft 15 is also locked against rotation relative to the housing 11 about the rotational axis 16.

The fingers 33 are also referred to as claw teeth, which in the locked position engage in corresponding recesses 34, also referred to as pockets. The respective pocket preferably has at least one relief ramp, so that the claw can only be moved into the pocket and the transmission output shaft 15 can only be fixed to the housing 11 in a rotationally fixed manner when the transmission output shaft 15 is rotating about the axis of rotation 16 relative to the housing 11 with only a low rotational speed or when the transmission output shaft 15 is at a standstill. The respective escape ramp is formed, for example, by at least one wall region, in particular a wall region of the housing 11, wherein this wall region at least partially delimits a respective pocket, in particular in the circumferential direction of the transmission output shaft 15 or the lock wheel 29. The circumferential direction of the transmission output shaft 15 or the locking wheel 29 extends about the axis of rotation 16 and therefore lies in a plane which extends perpendicularly to the axis of rotation 16. The wall region extends, for example, obliquely to the axis of rotation 16 or lies in a plane extending obliquely to the axis of rotation 16. In this case, the wall region extends in particular at an angle to the axis of rotation 16 such that it or a pocket at least partially delimited by it widens in the axial direction of the transmission output shaft 15 toward the locking wheel 29 or toward the release position.

Thus, if, for example, the locking wheel 29 is initially in the release position, while the transmission output shaft 15 rotates about the rotational axis 16 relative to the housing 11 at a rotational speed which is too high for the locking wheel 29 to move from the release position to the locking position, and then, for example, an attempt is made via the lever 21 to move the locking wheel 29 from the release position to the locking position, so that the locking wheel 29 moves a distance from the release position toward the respective pocket and thus toward the locking position, the locking wheel 29 is moved back again, in particular pushed, by means of the respective escape ramp toward the release position, or is moved back again, in particular pushed, into the release position, because, for example, a force is formed as a result of the locking wheel 29, in particular the respective pawl, interacting with the escape ramp, which force is directed toward the release position, acts on the locking wheel 29 and thus moves the locking wheel, In particular to push the locking wheel into the release position. Thereby excessive loads can be avoided.

In summary, it can be seen that a particularly robust and simple-to-operate protection against unintentional rolling away can be achieved by means of the transmission 10, so that the motorcycle 1 as a whole can be particularly advantageously protected against unintentional rolling away and at the same time can be operated simply.
