Technical Field

The present disclosure relates to a speed sensor, a fastening mechanism for a speed sensor, a receiving device for a speed sensor, a sensor system with a receiving device and a speed sensor, and a method for the rotationally fixed positioning of a speed sensor.

Background

Document DE 102008054000B 4 describes a device for self-adjustment and a method for arranging a pulse rate sensor in relation to a rotor. For a positionally correct installation, a contour is introduced either on the sensor or on the clamping sleeve, which contour allows a positionally correct installation.

Disclosure of Invention

Against this background, the object of the present invention is to provide an improved tachometer, an improved fastening device for a tachometer, an improved receptacle device for a tachometer, an improved sensor system with a receptacle device and a tachometer, and an improved method for the rotationally fixed positioning of a tachometer.

This object is achieved by a rotational speed sensor, a fastening device, a receiving device, a sensor system and finally by a method according to the independent claims.

An advantage that can be achieved with the proposed solution is that a stable, rotationally fixed positioning of the rotation rate sensor can be achieved in a simple manner, while optionally allowing an axial movement of the rotation rate sensor. Furthermore, this movement can be achieved by a clamping sleeve which is mounted together with a rotational speed sensor.

The tachometer sensor has a cylindrical sensor head with a measuring tip and a tongue. The tongue is disposed on an outer diameter of the sensor head and is shaped to: a twist stop as a rotational speed sensor is fitted with a corresponding contour of the fastening mechanism.

The tacho sensor may be an active tacho sensor, which may also be referred to as a pulse tacho sensor, for example. The sensor head of the tacho sensor may be formed integrally with the measuring tip and the tongue. However, the sensor head can also have a first component in the form of a cylindrical base body and a second component with a measuring tip, wherein the first component and the second component are coupled to one another. The tongue may be formed integrally with the first member or the second member. Alternatively, the tongue may be connected to the first member or the second member as a separate component. For example, the measuring tip can be shaped as a free end of the rotation speed sensor. The measuring tip can be designed for sensing the rotational speed of the rotor or of the pole rotor, for example. For this purpose, the measuring tip can have at least one hall sensor, which can be connected via a measuring and supply cable to provide a supply voltage. The rotational speed sensor proposed here can be coupled in a rotationally fixed manner by means of the tongues in or on a fastening mechanism, which is to be understood as a stationary machine part. The fixing mechanism may have at least one fixing member. In this case, it is still possible to realize an axial displacement of the rotational speed sensor, for example, with respect to the rotor or the pole rotor. The rotational speed sensor proposed here can therefore be mounted in a positive manner due to the slight special shaping of the tongue, wherein the rotational speed sensor can even be moved on the shaft. The tongue arranged directly on the sensor head can in this case achieve a particularly stable form-fitting rotational stop. The tongue can thus also rest against a surface formed directly on the shaft, for example, and fix the sensor in a rotationally fixed manner. This entails the advantage that not only conventional but also rotation-resistant sensors can be fixed in the same receptacle.

The tongue may extend radially away from the sensor head. The tongue may, for example, extend radially away from the cylindrical section of the second member. The tongue may be rectangular in shape. This enables a stable form-fitting rotationally fixed fixing of the sensor head. The sides of the tongue may be shaped planarly. The tongue may be shaped without protrusions or projections in the longitudinal direction of the sensor head. In order to prevent rotation of the rotation speed sensor, the tongue can abut against the counter contour or stop against the counter contour. For example, the tongue can project into the corresponding contour or act on the corresponding contour as a rotation stop. A very stable twist stop can thereby be achieved.

According to one embodiment, both side faces of the tongue can be shaped as stop faces for corresponding contours. The side faces may be two opposing and additionally or alternatively parallel extending side faces of the tongue. The two side faces can be arranged opposite one another transversely to the longitudinal axis of the sensor head. Thus, the tongue can be prevented from moving by the two side faces, and the rotation of the rotation speed sensor can be prevented.

The tongue can be arranged on the end of the sensor head facing away from the measuring tip. This makes it possible to easily achieve a twist stop during installation.

It is also advantageous if the end face of the tongue has a tongue groove as a stop face for the corresponding contour. The end face may be shaped as the outermost free end of the tongue. For example, the end face can be arranged to extend transversely to the side faces and connect these side faces. The tongue groove may enter the end face in a semi-circular shape. In such a tongue groove, only a simple fastening mechanism with only a single fastening element, such as a pin, which is guided into the tongue groove, can be used for the rotational locking in order to prevent a lateral movement of the rotational speed sensor. Alternatively, the end face may be shaped as a planar stop face. This form can be realized cost-effectively.

The fastening means for the rotational speed sensor described above have a counter contour which can be coupled with a tongue of the rotational speed sensor for rotationally fixedly positioning the rotational speed sensor. The corresponding contour and the tongue can be positively coupled to one another. The fixing means may represent a stationary machine part or may be rigidly fixed to a stationary machine part. In order to fasten the fastening device to a stationary machine part, the fastening device can have at least one fastening element in the form of a screw, a rod, a bolt, a bearing body and an additional or alternative connecting plate or be coupled to at least one such fastening element. The fastening means can also be formed directly on the receptacle.

The counter contour can have, for example, a flat surface against which the web bears in a rotationally fixed manner. Alternatively, the corresponding contour may be shaped as a receiving groove for receiving the tongue or as a projection for projecting into a tongue groove of the tongue or as at least one projection as a corresponding stop surface for the tongue. The receiving groove may for example have a rectangular cross section for receiving a substantially rectangular tongue. The receiving groove can be molded, for example, in a fastening part shaped as a bearing body. The projection can be, for example, an arched or angular outer surface of a rod-shaped fastener, wherein the rod can be guided into the tongue groove. The corresponding profile may also comprise two protrusions which may serve on both sides as two corresponding stop surfaces for both side surfaces of the tongue. The tongue can be arranged, for example, between two projections, in order to prevent a lateral movement of the tongue by positive locking of the two projections. One or both of the projections may be shaped like a bar.

The receiving device for one of the previously proposed rotation rate sensors has a receiving body for receiving at least one section of the sensor head and the previously proposed fastening means. The receiving body may typically be a hole in a shaft for receiving the sensor. Or in another embodiment, the receiving body can also be shaped in the form of a hollow cylinder, for example in the form of a tube. The receiving body may be shaped to fit on a vehicle, such as a truck or trailer. For example, the outer surface of the receiving body can have one or more welded webs. Such a receiving device makes possible a stable and protected receiving for the rotationally fixed support of the rotational speed sensor.

The receiving body and the fastening means of the receiving device can be formed in one piece, or the fastening means can be connected to the receiving body in a form-fitting, force-fitting and/or additionally or alternatively in a material-fitting manner. The fastening means can be screwed, clamped, glued, cast or welded to the receiving body.

The sensor system has one of the previously proposed receiving device and the previously proposed rotation speed sensor, wherein the tongue of the rotation speed sensor is or can be coupled to the counter contour in a rotationally fixed manner. For example, the tongue can be coupled in a rotationally fixed manner to the counter contour in a receiving position of the rotation rate sensor, which is received in the receiving body. In this case, the tongues and the surfaces of the counter contour that prevent rotation can abut against one another without play. The rotational speed sensor can be linearly movable in the receiving body along the axis of the receiving body in the receiving position. The sensor system according to the invention has the advantage that both conventional passive (non-torsionally stiff) and active (torsionally stiff) tacho sensors can thus be installed in the same device.

The method for rotationally fixed positioning of one of the previously proposed rotational speed sensors on a fastening means has an arrangement step. In the setting step, a tongue of the rotation speed sensor is arranged in or on a corresponding contour of the fastening means, wherein the tongue is arranged in the setting step in such a way that it interacts with the corresponding contour, for example protrudes into or acts on the corresponding contour, for the rotationally fixed positioning of the rotation speed sensor.

Detailed Description

Fig. 1 shows a side view of a tachometer sensor 100 according to an embodiment.

The tacho sensor 100 has a cylindrical sensor head 105 with a measuring tip 110 and a tongue 115. The tongue 115 is arranged on the outer diameter 120 of the sensor head 105 and is shaped so as to interact as a twist stop for the tachometer sensor 100 with a corresponding contour of the fastening mechanism, for example, protrudes into or acts on this corresponding contour.

The rotation speed sensor 100 is configured to sense the rotation speed of the rotor 125 or the magnetic pole rotor, for example. For this purpose, according to this exemplary embodiment, the measuring tip 110, which forms the free end of the rotational speed sensor 100, is arranged toward the rotor 125. According to this embodiment, the tacho sensor 100 is shaped as an active tacho sensor 100. According to this exemplary embodiment, the tacho sensor 100 has a first component 130, which is shaped as a cylindrical base body of the sensor head 105. The rotor 125 is positioned opposite the rotational speed sensor 100 and in particular opposite the measuring tip 110. The measuring tip 110 is arranged on the end of the rotational speed sensor 100 facing the rotor 125, in this case on the end of the first component 130 facing the rotor 125. Furthermore, the rotational speed sensor 100 has a second component 135, which is shaped as a tongue 115 and a cable outlet 150. The first component 130 and the second component 135 are axially connected to one another in a rotationally fixed form-fit, force-fit and/or material-fit manner according to this exemplary embodiment. According to an alternative embodiment, the tongue 115 is arranged on the first component 130 or the entire tachometer sensor 100 is integrally formed.

The tongue 115 according to this embodiment extends radially away from the sensor head 105. In this case, according to this exemplary embodiment, the tongue 115 extends from a cylindrical section of the second component 135, which extends flush with the base body, away from and/or perpendicular to the cylinder center axis 140 or longitudinal axis of the cylindrical sensor head 105. The tongue 115 is arranged according to this embodiment on the end of the sensor head 105 facing away from the measuring tip 110. The tongue 115 has a rectangular cross-section.

On the side of the outer diameter 120 facing away from the tongue 115, the sensor head 105 has according to this embodiment a direction indicator 145 which is shaped in order to enable a rotationally correct orientation of the sensor 100. The direction indicator 145 is, for example, shaped as a small protrusion beyond the outer diameter 120 or is placed into the outer diameter 120.

The tachometer sensor 100 proposed here, due to the tongue 115, forms an interface for the rotationally fixed mounting of the active tachometer sensor 100. The tongue 115 may also be referred to as an "element for rotating the correct orientation". In the case of the active speed sensor 100, a positionally correct mounting of the rotor 125 is necessary, the sensor 100 being displaceable in the receptacle along the cylinder axis 140, for example by means of a clamping sleeve, for which purpose see also fig. 7 to 12.

In fig. 1, a section axis a-a is shown, to which fig. 2 to 5 relate.

Fig. 2 shows a front cross-sectional view of a tachometer sensor 100 according to an embodiment. One exemplary embodiment of a rotational speed sensor 100 according to fig. 1 may be mentioned, which is shown in cross section along the axis a-a shown in fig. 1. The rotation speed sensor 100 is shown rotated by 90 ° to the observer relative to the rotation speed sensor 100 shown in fig. 1.

As can be seen in fig. 2, the tongue 115 has two side faces 200 which, according to this embodiment, extend parallel to one another. The end surfaces 205 of the tongues connect the side surfaces 200 to each other and form the outermost ends of the tongues 115. The end surface 205 is convex shaped according to this embodiment. According to an alternative embodiment, the end surface 205 is concavely or perpendicularly oriented with respect to the side surface 200. Furthermore, a spanner surface 210 is shown in fig. 2.

Two further sides of the tongue 115, which are oriented transversely to the sides 200 and connect them to one another, can optionally be used to fix the yaw rate sensor 100 along the longitudinal axis of the yaw rate sensor 100.

Fig. 3a again shows a sectional plane a-a of the tacho sensor 100 and the fixing means 300 according to an embodiment. The rotational speed sensor 100 described in fig. 2 may be used here.

The fastening means 300 is shaped for rotationally fixedly positioning the tachometer sensor 100. For this purpose, the fixing mechanism 300 has a corresponding contour, which can be coupled with a tongue of the tachometer sensor 100. According to this embodiment, the corresponding profile is shaped for at least one corresponding stop surface of the tongue 115. According to this embodiment, the securing mechanism 300 comprises two securing members 305, each shaped as a corresponding stop surface for the tongue 115. The fastening element 305 is shaped like a rod and/or extends transversely to the extension direction of the tongue 115 and/or is arranged adjacent to each of the side faces 200 or end faces 205 of the tongue 115. Merely by way of example, the rod-shaped fixing element 305 is shaped according to this embodiment as a cylinder. That is, the tongue 115 is disposed between the two fasteners 305 according to this implementation. The side 200 of the tongue 115 is here shaped as a stop surface for a corresponding contour. Alternatively, the fixture 305 may have other suitable shapes.

The securing mechanism 300 may also be referred to as a "securing member for rotating the sensor in the proper orientation". According to an alternative embodiment, at least one of the fastening means 300 or the fastening element 305 or both fastening elements 305 are formed as a screw stop, a screw or a web or are directly part of the receiving means for the sensor.

According to this exemplary embodiment, a further direction indicator 310 is arranged on a mounting device for mounting the yaw rate sensor 100 in a receiving device for supporting the yaw rate sensor 100, wherein the further direction indicator 310 enables an orientation of the yaw rate sensor 100. The containment device is described in more detail in fig. 7 to 12.

Fig. 3b again shows a sectional plane a-a of the tacho sensor 100 and the fixation mechanism 300 according to an embodiment. The rotational speed sensor 100 described in fig. 2 may be used here.

The tongue end face 205 is shaped vertically as described with reference to fig. 1 and extends parallel to a stop face of the fastening mechanism 300, which serves as a counter contour for the torque-proof fastening. In this example, only one single surface is used for the rotational stop. The larger the shaping of the stop surface 205 with the corresponding contour, the smaller the angular error that is permitted by this fixing and that arises.

FIG. 4 illustrates a cross-sectional view A-A of FIG. 1 of the tachometer sensor 100 and a securing mechanism 300 in accordance with one embodiment. The tachometer sensor 100 illustrated in fig. 2 or 3 may be used here, with the only difference that the front side 205 of the tongue 115 has a tongue groove 400. The securing mechanism 300 may include only one of the securing members described in fig. 3, which is partially received in the tongue groove 400 according to this embodiment. The fastening means are shaped here as a projection as a corresponding contour for the tongue 115, which projection projects into the tongue groove 400. The tongue groove 400 is arranged according to this embodiment in the middle and/or semi-circularly in the end face 205. The tongue groove 400 acts as a stop surface for the corresponding profile of the securing mechanism 300 according to this embodiment.

FIG. 5 illustrates a cross-sectional view A-A of FIG. 1 of the tachometer sensor 100 and a securing mechanism 300 in accordance with one embodiment. The rotational speed sensor 100 described in fig. 2 may be used here. The securing mechanism 300 according to this embodiment has a bearing body 500 with a corresponding contour in the form of a receiving groove 505 shaped for receiving a tongue. The two mutually facing groove inner faces 510 of the receiving groove 505 are shaped according to this embodiment as one respective stop face for the side faces of the tongue arranged in the receiving groove 505.

The bearing body 500 according to this exemplary embodiment has one or two through-holes, here for example holes 515, which are used to receive at least one screw or rod. The two bores 515 according to this exemplary embodiment are arranged one behind the other, i.e. in the extension of the depth of the receiving groove 505. The holes 515 according to this embodiment each extend transversely to the depth of the receiving groove 505 and parallel to the longitudinal axis of the tachometer sensor 100.

According to one embodiment, a respective one of the fastening elements is guided through each of the holes 515, by means of which the fastening mechanism 300 can be fastened, for example, on a fixed machine part, as shown in fig. 7.

Fig. 6 shows a cross-sectional side view of a tachometer sensor 100 having a securing mechanism 300 according to an embodiment. The rotational speed sensor 100 and the fastening means 300 described in fig. 5 can be referred to here. The fixing element 615, which is guided through a bore, according to this exemplary embodiment relates to two screws. Although the tachometer sensor 100 is mounted in a rotationally fixed manner in the fastening means 300, the tachometer sensor 100 can still be displaced in the axial direction, i.e. along its longitudinal axis.

Fig. 7 shows a cross-sectional side view of a sensor system 700 comprising a receiving device 705 with a fastening mechanism 300 and a rotational speed sensor 100 according to an embodiment. The fixing mechanism 300 may relate to the fixing mechanism 300 described in fig. 6, and the rotation speed sensor 100 may relate to the rotation speed sensor 100 described in fig. 6. Sensor system 700 has a receiving device 705 and a rotational speed sensor 100. The receiving device 705 in turn has a receiving body 710, which is shaped to receive at least one section of the sensor head 105, and the fastening means 300. The receiving body 710 according to this exemplary embodiment has a cylindrical receiving bore 711, in which the cylindrical base body of the sensor head 105 is received at least partially by means of a clamping sleeve 720. The receiving body 710 and the fastening means 300 can be connected to one another in a form-fitting, force-fitting and/or material-fitting manner. According to this embodiment, a form-fitting connection and additionally a non-fitting connection are present. For this purpose, a fastening element 615 of the fastening mechanism 300, which is realized as a screw, is provided through a hole in the fastening mechanism 300 and screwed into the receiving body 710. Further, the fixing mechanism 300 and the accommodating body 710 are stopped from each other by a stopper mechanism 712. The latching means 712 here comprise suitable interengaging contours which are formed on mutually opposite faces of the fastening means 300 and the receiving body 710. For example, the fastening mechanism 300 has one or more projections for this purpose, while the receiving body 710 has one or more corresponding recesses, or vice versa.

In the cylindrical bore of the receiving body 710, the tachometer sensor 100 is arranged in a linearly movable manner parallel to its longitudinal axis by means of a clamping sleeve 720. A clamping sleeve 720 is arranged in the circumferential gap between the sensor head 105 and the wall of the receiving bore 711. The clamping sleeve 720 may have one or more spring elements, which may be supported on the circumferential wall of the receiving bore 711 and may be pressed against the sensor head 105 in order to hold the sensor head 105 in the receiving bore 711 in a linearly movable manner.

At the receiving point 715 of the tachometer sensor 100 shown here, which is received in the receiving body 710, the tongue 115 and thus the entire tachometer sensor 100 is coupled in a rotationally fixed manner to a corresponding contour of the fastening means 300, which contour is formed by the receiving groove 505. According to this embodiment, the accommodation groove 505 is continuously formed in the longitudinal direction of the rotation speed sensor 100 over the entire length of the fixing mechanism 300. In this way, the rotation speed sensor 100 is freely movable in the longitudinal direction.

The sensor, which is embodied here as a tachometer sensor 100, is rotationally fixed according to this exemplary embodiment by the fastening means 300 in the form of a further component and is mounted correctly in the receptacle 710, which is present in the form of a shaft, which shaft furthermore makes it possible to move the tachometer sensor 100 in the axial direction. According to this embodiment, only the hole/thread for the fixing mechanism 300 is mounted on the accommodating body 710 in parallel with the receiving hole 711 on the outer wall of the accommodating body 710 in the form of a fixing plate. According to an alternative embodiment, the fastening means 300 is cast directly onto the receiving body 710 in the form of a fastening profile. Thereby eliminating the need for additional fixing means, such as for example one or more screws.

According to one embodiment, the bearing body may be a stamped and bent piece. In addition to or instead of the screw and/or detent mechanism 712 shown here, the fastening mechanism 300 according to an alternative embodiment has at least one slot-key connection and/or slot-slot connection and/or rivet.

According to an alternative embodiment, the fastening means 300 can relate to one of the fastening means 300 described with reference to one of fig. 3 to 5, which is connected to the receiving body 710 in one piece or in a form-fitting, material-fitting and/or force-fitting manner.

Fig. 8 illustrates a cross-sectional view of a side of a containment device 705 in accordance with one embodiment. The receiving device 705 illustrated in fig. 7 can be used here, with the difference that the fastening means 300 is formed as a projection of the receiving device 705. The securing mechanism 300 is shaped as a receiving groove 505 as described according to fig. 7. According to an alternative embodiment, the fastening means 300 is formed by two fastening elements 305, for example in the form of bars, as described with reference to fig. 3.

The receiving body 710 is formed integrally with the fastening mechanism 300 according to this exemplary embodiment. The outer diameter of the receiving body 710 has according to this embodiment one or more webs 800 which are shaped, for example, for mounting the receiving device 705 on a truck or trailer.

According to this embodiment, the securing mechanism 300 is mounted directly on a receiving body 710 in the form of a holder or handle in the form of a rotation stop, as is often used in trailers. The fastening mechanism 300 allows an expansion of the receiving body 710 in the form of a mounting device with a fastening element for the positionally correct mounting of the sensor. The receiving body 710 is shaped according to this embodiment as a tube with a welded or screwed connection plate 800 as a sensor receiving portion, for example on a trailer or truck. According to an alternative embodiment, the receiving body 710 has a clearance and/or clamping sleeve for guiding the sensor directly in the tube. As a further advantageous embodiment, the receiving device 705 comprises means for a punch-out element for fixing.

Fig. 9 shows a cross-sectional view of the front of the containment device 705 according to one embodiment. One exemplary embodiment of a receiving device 705 according to fig. 8 can be mentioned, which receiving device 705 is shown in a sectional view along a sectional axis B-B shown in fig. 8. Thus, the cross-section extends through the securing mechanism 300.

The receiving device 705 is shown rotated by 90 ° to the observer relative to the receiving device 705 shown in fig. 8. Fig. 9 shows that two mutually opposite fastening elements 305 are formed by the receiving groove 505, which according to this exemplary embodiment each have the shape of a circular ring segment in cross section. The two inner faces of the fastening element 305 facing each other run parallel to each other according to this exemplary embodiment and form a groove inner face which serves as a stop face for the side face of the tongue of the tachometer sensor 100.

Fig. 10 illustrates a cross-sectional view of a side of a sensor system 700 according to an embodiment. The sensor system 700 illustrated in fig. 7 can be used here, with the difference that the receiving device 705 corresponds to the receiving device 705 illustrated in fig. 8 or 9. Rotational speed sensor 100 is arranged in a receiving position of receiving device 705 and is mounted in a rotationally fixed but linearly movable manner by means of a fastening mechanism.

Fig. 11 illustrates a cross-sectional view of a side of a sensor system 700 according to an embodiment. This may involve the sensor system 700 described in fig. 10. The tachometer sensor 100 is formed in one piece according to this embodiment. The securing mechanism 300 is shaped to receive a protrusion of the device 705.

Fig. 12 illustrates a cross-sectional view of a side of a containment device 705 in accordance with one embodiment. This may involve the receiving device 705 described in fig. 11. The fastening means 300 can be one of the fastening means 300 described with reference to fig. 3 to 11, which is connected to the receiving body in one piece or form-fit, material-fit and/or force-fit.

Fig. 13 shows a flow diagram of a method 1300 for rotationally fixed positioning of a rotation speed sensor on a fastening device according to an exemplary embodiment. One of the rotational speed sensors described in one of fig. 1 to 12 and one of the fastening means described in one of fig. 3 to 12 can be used.

The method 1300 has a setting step 1305 in which a tongue of the tachometer is set into or onto a corresponding contour of the fastening means, wherein the tongue is set in the setting step 1300 in such a way that it interacts with the corresponding contour, i.e. for example protrudes into or acts on the corresponding contour, in order to position the tachometer in a rotationally fixed manner.

Optionally, the method 1300 has a providing step 1310 before the providing step 1305, wherein a rotational speed sensor and a fixing mechanism are provided in the providing step 1310.

If an embodiment includes an "and/or" relationship between the first feature and the second feature, this can be interpreted as meaning that the embodiment has not only the first feature but also the second feature according to one embodiment and either only the first feature or only the second feature according to another embodiment.
