Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a first embodiment of the shifting system of the present invention, wherein a shift cable 20 is connected to a right end of a shift lever 104.

As shown in fig. 2, the transmission shift system includes a shifter 10, a transmission 30, and a shift cable 20.

The gear shifter 10 comprises a gear shift lever 101, one end of the gear shift lever 101 is a driving end 101a, the driving end 101a is exposed out of the gear shifter 10, the other end of the gear shift lever 101 is a transmission end 101b and is located in the gear shifter 10, the middle of the gear shift lever 101 is rotatably connected to a first rotating fulcrum 102 arranged on the gear shifter 10, and when a driver performs a gear shifting operation, the driving end 101a can be manually operated to enable the gear shift lever 101 to rotate around the first rotating fulcrum 102. In fig. 2, the driving end 101a of the shift lever 101 is marked with P, R, N, D four gears, i.e. parking gear, reverse gear, neutral gear and forward gear, when the driver operates the driving end 101a of the shift lever 101 to reach the corresponding gear, he/she will want to shift gears, and in fig. 2, when the shift lever 101 rotates clockwise, he/she will want to switch to P, R, N, D.

The transmission 30 includes a shift rocker 301, and the shift rocker 301 rotates to shift the gear of the transmission 30, so as to actually convert the driver's shift intention into a gear change on the transmission 30. In fig. 2, the transmission 30 is arranged such that when the shift rocker 301 is rotated counterclockwise, the gears are sequentially switched to P, R, N, D.

The shift cable 20 transmits the rotation of the shift lever 101 of the shifter 10 to the shift rocker 301, but may be provided with another structure to transmit the shift driving force.

It should be noted that in the present embodiment, the shift lever 104 and the shift link 103 are disposed in the shifter 10, and the second pivot point 105 is further disposed, and the second pivot point 105 may be fixed inside the housing of the shifter 10, may be disposed separately from the housing of the shifter 10, and fixed by fastening or welding, for example, or may be directly integrated into the housing of the shifter 10. The middle portion of shift lever 104 is rotatable around second pivot point 105, and the middle portion refers to the portion between two ends of shift lever 104, and is not limited to the middle portion of shift lever 104, as long as the lever segments of shift lever 104 located on two sides of second pivot point 105 can be connected with the corresponding structures and achieve the required rotation transmission. The specific configurations of the second rotation fulcrum 105 and the first rotation fulcrum 102 are not limited as long as the rotation of the shift lever 101 and the shift lever 104 can be achieved.

In order to realize the transmission of rotation, the gear shifting connecting rod 103, the gear shifting rod 101, the gear shifting lever 104 and the gear shifting rocker arm 301 rotate in the whole vehicle ZX plane, wherein Z is vertical, and X is the longitudinal direction of the vehicle. The shift link 103 can be articulated or ball-jointed with the shift lever 101 and the shift lever 104, the ball joint has higher flexibility, can easily compensate the possible deviation in the transmission chain, ensures the smooth transmission of the rotation, and is a relatively preferable connection mode, when articulated, obviously, in order to realize the transmission of the rotation, the axis of the articulation is parallel to the direction of the rotation axis of the shift lever 101 around the first rotation fulcrum 102 and the rotation axis of the shift lever 104 around the second rotation fulcrum 105, namely, the rotation axes rotate in the ZX plane.

Shift link 103 serves as a link between shift lever 101 and shift lever 104, and for convenience of description, both ends of shift lever 104 are defined as first end 104a and second end 104b, respectively, corresponding to right and left ends in fig. 2. One end of the shift link 103 is connected to the transmission end 101b of the shift lever 101, and the other end is connected to the first end 104a of the shift lever 104, so that the shift lever 101 drives the shift link 103 to move when rotating, and then drives the shift lever 104 to rotate, thereby realizing linkage.

The specific operation flow is as follows:

operating the drive end 101a of the shift lever 101 to rotate clockwise, with the shift intent in turn P, R, N, D;

the transmission end 101b of the shift lever 101 also rotates clockwise, driving the shift link 103 to move, and then driving the first end 104a (i.e., the right end) of the shift lever 104 to rotate counterclockwise;

since the shift cable 20 is connected to the first end 104a of the shift lever 101, the shift rocker 301 rotates counterclockwise under the pushing action of the shift cable 20, so that P, R, N, D switching is realized sequentially, and the intention of shifting is consistent;

if the gear shift lever 101 is rotated anticlockwise in the reverse direction, the gear shift link 103 and the gear shift lever 104 also rotate reversely, the gear shift cable 20 pulls the gear shift rocker 301 to rotate clockwise, switching of D, N, R, P is sequentially achieved, and details are not repeated and are consistent with gear shift intentions.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a second embodiment of the gear shifting system of the present invention, wherein a shift cable 20 is connected to a left end of a shift lever 104.

In this embodiment, the structure is the same as that of the above embodiment, except that the motion pattern of the shift rocker 301 of the transmission 30 is reversed, that is, when the shift rocker 301 rotates counterclockwise, the corresponding gear is D, N, R, P in sequence, and when the shift rocker 301 rotates clockwise, the gear is P, R, N, D in sequence. At this time, in order to match the movement setting of the shift rocker 301, the shift cable 20 is connected to the second end 104b (i.e., the left end in fig. 3) of the shift lever 104, differently from the connection of fig. 2.

The specific operation flow is as follows:

operating the drive end 101a of the shift lever 101 to rotate clockwise, with the shift intent in turn P, R, N, D;

the transmission end 101b of the shift lever 101 also rotates clockwise, driving the shift link 103 to move, and then driving the second end 104b (i.e. left end) of the shift lever 104 to rotate counterclockwise;

because the gear shifting cable 20 is connected to the second end 104b of the gear shifting lever 104, under the pulling action of the gear shifting cable 20, the gear shifting rocker arm 301 rotates clockwise, so that P, R, N, D switching is realized in sequence, and the gear shifting intention is consistent;

if the gear shift lever 101 is rotated anticlockwise in the reverse direction, the gear shift link 103 and the gear shift lever 104 are also rotated anticlockwise, the gear shift cable 20 pushes the gear shift rocker 301 to rotate anticlockwise, and switching of D, N, R, P is sequentially achieved, which is consistent with the gear shift intention, and details are not described again.

It can be seen that, since the shift lever 104 is disposed in the shifter 10, the rotation of the shift lever 101 drives the shift lever 104 to rotate, and the shift cable 20 connecting the shift rocker 301 and the shifter 10 can be selectively connected to the first end 104a or the second end 104b of the shift lever 104 according to the movement pattern of the shift rocker 301 in the transmission 30, so as to ensure that the gear shift setting of the shift lever 101 matches the gear shift of the shift rocker 301. That is, after the gear shifter 10 in the embodiment is provided with the gear shift lever 104, the gear shift rocker 301 of the transmission 30 in the counterclockwise direction can be matched, the gear shift rocker 301 of the transmission 30 in the clockwise direction can also be matched, the limitation of the movement form of the gear shift rocker 301 of the transmission 30 is avoided, and the flexibility of the arrangement direction and the form of the transmission 30 in the whole vehicle is increased.

It can be understood that in the above embodiments, mainly a rotatable shift lever 104 is added to the transmission chain of the shift lever 101 and the transmission 30, and either end of the shift lever 104 can drive the shift rocker 301 to rotate, and the driving directions of the different ends are different, and for the sake of clarity, in fig. 2 and 3, D, N, R, P is marked at the first end 104a of the shift lever 104, i.e. connected to the first end 104a, and can match the transmission 30 which operates in the clockwise direction to realize D, N, R, P shifting, and P, R, N, D is marked at the second end 104b of the shift lever 104, i.e. connected to the second end 104b, and can match the transmission 30 which operates in the clockwise direction to realize P, R, N, D shifting.

Here, a shift link 103 is further provided in order to transmit the rotation of the shift lever 101 to the shift lever 104. It should be noted that, the shift lever 101 and the shift lever 104 rotate around different rotation pivots respectively, and the linkage of the shift lever 101 and the shift lever 104 must be realized by means of the transmission portion, so as to compensate the relative distance change between the shift lever 101 and the shift lever 104 during rotation. It is understood that the transmission part may be other transmission connecting members, not limited to the transmission link, for example, the transmission connecting member may also be a shift connecting cable, and of course, the transmission performance of the shift connecting rod 103 is more reliable, which is a relatively more preferable scheme.

The transmission between shift lever 104 and shift lever 101 is not limited to the above-mentioned transmission linkage, but may also be a slide and slide rail 106, i.e. shift lever 104 and shift lever 101 are connected by a slide pair.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a third embodiment of the gear shifting system of the present invention, wherein a shift cable 20 is connected to a left end of a shift lever 104.

Specifically, either one of the shift lever 104 and the shift lever 101 may be provided with a slider, and the other one is provided with a slide rail 106, and the slider is slidably engaged with the slide rail 106, so that when the shift lever 101 rotates, the shift lever 104 can be driven to rotate, and the two can slide relatively through the slider, so as to compensate for the change of the relative distance between the two during the rotation. The slider may be fixed to the transmission end 101b of the shift lever 101 in a split or integrated manner, in fig. 4, the transmission end 101b itself forms a slider, i.e. the slider is integrally formed on the transmission end 101b, or the first end 104a of the shift lever 104 is fixed to the slider in a split or integrated manner; the shift lever 101 or the shift lever 104, which is not provided with a slider, may be provided with a matching slide rail 106, and the slide rail 106 may also be integrally or separately provided to the shift lever 101 or the shift lever 104. In fig. 4, a slide rail 106 is disposed on the lever body of the shift lever 104 near the first end 104a, and the first end 104a of the shift lever 104 is used for connecting with the shift cable 20.

The specific operation flow is as follows:

operating the drive end 101a of the shift lever 101 to rotate clockwise, with the shift intent in turn P, R, N, D;

the driving end 101b of the shift lever 101 also rotates clockwise to drive the first end 104a (i.e. the right end) of the shift lever 104 to rotate counterclockwise, and the change of the rotating distance is offset by the sliding of the sliding block and the sliding rail 106;

since the shift cable 20 is connected to the first end 104a of the shift lever 101, the shift rocker 301 rotates counterclockwise under the pushing action of the shift cable 20, so that P, R, N, D switching is realized sequentially, and the intention of shifting is consistent;

if the gear shift lever 101 is rotated anticlockwise in the reverse direction, the gear shift link 103 and the gear shift lever 104 also rotate reversely, the gear shift cable 20 pulls the gear shift rocker 301 to rotate clockwise, switching of D, N, R, P is sequentially achieved, and details are not repeated and are consistent with gear shift intentions.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a fourth embodiment of the gearshift system of the present invention, wherein a gearshift cable 20 is connected to the left end of a gearshift lever 104.

In this embodiment, the structure is the same as that of the third embodiment, except that the motion pattern of the shift rocker 301 of the transmission 30 is reversed, that is, when the shift rocker 301 rotates counterclockwise, the corresponding gear is D, N, R, P in sequence, and when the shift rocker 301 rotates clockwise, the gear is P, R, N, D in sequence. At this time, in order to match the movement setting of the shift rocker 301, the shift cable 20 is connected to the second end 104b (i.e., the left end in fig. 5) of the shift lever 104, differently from the connection of fig. 4.

The specific operation flow is as follows:

operating the drive end 101a of the shift lever 101 to rotate clockwise, with the shift intent in turn P, R, N, D;

the driving end 101b of the shift lever 101 also rotates clockwise to drive the second end 104b (i.e. the left end) of the shift lever 104 to rotate counterclockwise, and the change of the rotating distance is offset by the sliding of the sliding block and the sliding rail 106;

because the shift cable 20 is connected to the second end 104b of the shift cylinder rod 104, under the pulling action of the shift cable 20, the shift rocker 301 rotates clockwise, so that P, R, N, D switching is realized in sequence, and the intention of shifting is consistent with the intention of shifting;

if the gear shift lever 101 is rotated anticlockwise in the reverse direction, the gear shift link 103 and the gear shift lever 104 are also rotated anticlockwise, the gear shift cable 20 pushes the gear shift rocker 301 to rotate anticlockwise, and switching of D, N, R, P is sequentially achieved, which is consistent with the gear shift intention, and details are not described again.

This scheme still provides an automatic keep off car, including foretell variable speed system of shifting, has the same technological effect with the above-mentioned variable speed system of shifting, no longer gives unnecessary details.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
