The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The existing pneumatic clutch actuating device pushes a clutch release bearing by a piston to enable a clutch to be engaged, and drives the clutch release bearing to return through a return spring to enable the clutch to be separated. However, adaptive compensation cannot be performed after the clutch plates are worn, and the clutch is likely to be disengaged or not completely engaged after the clutch plates are worn.

In view of the above, the present embodiment provides a clutch actuator, which can also drive a clutch release bearing to return by a piston to release a clutch, and can solve the above problems.

As shown in fig. 1, the clutch actuator includes a power mechanism, an output member 3 and a compensation structure 13, the power mechanism includes a cylinder body 7 and an actuating member 2, the cylinder body 7 has a cavity, a first passage 71 and a second passage 72, a reversing valve 5 selectively communicates an air source with the first passage 71 or the air source with the second passage 72, the actuating member 2 includes a piston 21, the piston 21 extends into the cylinder body 7 to divide the cavity into a first cavity and a second cavity, the first passage 71 communicates with the first cavity, the second passage 72 communicates with the second cavity, the piston 21 can reciprocate in the cavity, a first end of the output member 3 is connected with a clutch release rocker arm, one end of the compensation structure 13 abuts against the actuating member 2, and the other end abuts against a second end of the output member 3, and the compensation structure 13 is configured to compensate for wear of a clutch plate when the clutch plate is worn. The compensating structure 13 may be a compression spring or a hydraulic strut, and in this embodiment, the compensating structure 13 is preferably a compression spring, one end of which abuts the actuating member and the other end of which abuts the second end of the output member 3.

Specifically, when the clutch plate is worn, the actuating part 2 drives the output part 3 to drive the clutch release rocker arm to separate or combine the clutch, and meanwhile, the compensation structure 13 compensates the wear of the clutch plate to drive the output part 3 to perform compensation action, so that the output part 3 is ensured to drive the clutch release rocker arm to perform accurate combination or separation action, and the problem that the clutch is not completely combined after the clutch plate is worn is avoided.

Optionally, as shown in fig. 1-2, the clutch actuator further comprises a first housing 11, a second housing 12, and an articulating assembly 4. The first housing 11 is a cylindrical structure with an opening at one end, and the cylinder main body 7 and the first housing 11 are fixedly connected by a bolt or welding, in this embodiment, the connection between the cylinder main body 7 and the first housing 11 is preferably a bolt. The actuator 2 is disposed in a space surrounded by an inner wall of the first housing 11 and slidably connected to the first housing 11.

The second housing 12 is a tubular structure with an opening at one end, and the end of the second housing 12 with the opening is sleeved on the inner side of the end of the first housing 11 with the opening, and the second housing 12 is slidably connected with the first housing 11. The compensation structure 13 is disposed in a space enclosed by the inner wall of the second housing 12. The second end of the output member 3 is fixedly connected with the second housing 12, and the connection mode can be welding or screwing, and is preferably screwing.

The movable connecting component 4 is arranged in the space enclosed by the inner wall of the second shell 12. Both ends of the compensating structure 13 abut against the second housing 12 and one end of the movable connecting assembly 4 facing the output member 3, respectively. Both sides of the movable connecting component 4 are respectively abutted with the actuating component 2 and the second shell 12.

Illustratively, the cylinder body 7 of the clutch actuator is divided by the piston 21 of the actuator 2 into a first chamber communicating with the first passage 71 of the cylinder body 7 and a second chamber communicating with the second passage 72 of the cylinder body 7. When the clutch needs to be disengaged, the first passage 71 of the cylinder main body 7 is closed and the second passage 72 is opened. The gas with a specific pressure value enters the second channel 72 of the cylinder body 7 to enter the second cavity and pushes the actuating part 2 to move for a fixed distance towards the first cavity. The actuator 2 slides in the first housing 11 while pressing and pushing the movable joint assembly 4. The movable connecting assembly 4 presses and pushes the second housing 12. The second shell 12 pushes the output part 3 to move, the output part 3 pushes the clutch release rocker, and the clutch release rocker pushes the clutch release bearing to realize the separation of the clutch. To ensure the disengaged state of the clutch, gas is continuously supplied to the second passage 72 of the cylinder body 7, and the disengaged position of the clutch actuator is locked.

It should be noted that the connection relationship between the clutch release rocker arm, the clutch release bearing and the clutch plate, and other related clutch components are well known in the art, and therefore will not be described herein. In this embodiment, the pushing action of the clutch actuator corresponds to the disengaging action of the clutch. The skilled person can also adjust the connection relationship between the clutch release rocker arm, the clutch release bearing and the clutch plate according to the actual engineering requirements, so as to correspond the pushing action of the clutch actuating device to the combining action of the clutch.

Further, when the clutch needs to be engaged, the first passage 71 of the cylinder main body 7 is opened and the second passage 72 is closed. The gas of a specific pressure value enters the first chamber through the first passage 71 of the cylinder body 7 and pushes the actuator 2 to move a fixed distance in the direction of the second chamber. Actuating member 2 gradually loses its squeezing pushing action on movable connecting member 4. Under the counterforce of the elastic parts of the clutch, the clutch release bearing reversely pushes the clutch release rocker, and the clutch is combined. The elastic component of the clutch itself may be a coil spring or a diaphragm spring. The clutch release rocker arm pushes back the output member 3. The output member 3 pushes back the second shell 12, and the second shell 12 pushes back the movable connecting component 4, so that two sides of the movable connecting component 4 are always kept in contact with the actuating member 2 and the second shell 12.

Further, as the clutch plates wear, the clutch needs to be engaged. If the clutch needs to be completely combined, the stroke of the clutch release rocker arm for reversely pushing the output member 3 is increased, the stroke of the output member 3 for reversely pushing the second shell 12 is increased, and the stroke of the second shell 12 for reversely pushing the movable connecting assembly 4 is increased. But the distance of movement of the actuator 2 in the direction of the second chamber does not change. The stroke of the clutch release rocker arm for pushing back the output member 3, the stroke of the output member 3 for pushing back the second housing 12 and the stroke of the second housing 12 for pushing back the movable connecting assembly 4 cannot be further increased. In this process, both sides of the movable connecting assembly 4 are always kept in contact with the actuator 2 and the second housing 12. At this time, when the clutch plate is worn, the compensation structure 13 may compensate for the stroke of the corresponding second housing 12 that pushes back the stroke increase of the movable connection assembly 4, compared to when the clutch plate is not worn.

In particular, the two ends of the compensation structure 13 abut against the second housing 12 and the end of the movable connection assembly 4 facing the output member 3, respectively. When the clutch plates wear, the stroke of the second housing 12 in the process of clutch engagement is increased to push back the movable connecting component 4. Both sides of the movable connecting assembly 4 are respectively abutted against the actuator 2 and the second housing 12. Because the stroke of the actuating member 2 is fixed, after the movable connecting component 4 reversely pushes a certain stroke, the second shell 12 cannot continuously realize the reverse pushing. At this time, the second housing 12 presses the compensation structure 13, and the compensation structure 13 is compressed until the second housing 12 reaches a thrust reversal stroke required when the clutch plate is worn, so that the clutch is fully engaged. In the process that the second shell 12 presses the compensation structure 13, two sides of the movable connecting component 4 are always kept in contact with the second shell 12 and the actuating piece 2, and the position of the movable connecting component 4 relative to the second shell 12 is not changed.

Similarly, when the clutch needs to be disengaged after the clutch plates are worn. The disengagement stroke of the clutch actuator will increase. Correspondingly, the actuating member 2 drives the movable connecting assembly 4, the movable connecting assembly 4 drives the second housing 12, and the movement stroke of the second housing 12 driving the output member 3 is increased. At this time, the compensation structure 13 firstly applies a reaction force to the second housing 12, so that the second housing 12 drives the output member 3, and further drives the corresponding clutch release rocker and the clutch release bearing to move, so as to eliminate a gap generated by wear of the clutch plates.

Specifically, actuator 2 further includes a connecting rod 22, a connecting member 23, and a conical member 24. The connecting rod 22 is fixedly connected with the piston 21 by means of bolts or welding, preferably bolts. One end of the connecting piece 23 is fixedly connected with the connecting rod 22, and the connecting mode can be screw connection or welding, and is preferably screw connection. The other end of the connecting piece 23 is fixedly connected with the conical piece 24, the other end of the connecting piece 23 is sleeved inside the conical piece 24, and the conical piece 24 is provided with a groove for installing a check ring.

Specifically, the movable connecting member 4 includes a rolling body 41 and a support 42. The support 42 has a receiving groove, and the rolling bodies 41 are disposed in the receiving groove of the support 42. The receiving groove, the cone 24, and the second housing 12 limit the rolling elements 41 together, and prevent the rolling elements 41 from falling off. The rolling elements 41 simultaneously abut against the cone 24 and the second housing 12, and both ends of the compensating structure 13 abut against the second housing 12 and the stay 42, respectively.

Further, the number of the receiving grooves of the support member 42 may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16, and the plurality of receiving grooves are uniformly arranged in an annular array. The rolling elements 41 may be balls or rollers, and in the present embodiment, the rolling elements 41 are preferably balls. The number of rolling elements 41 may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16.

The shifting piece 82 is provided with a sliding groove, and the shifting piece 82 is fixedly connected with the position sensor and is rotatably connected with the sensor seat 83. One end of the pin 81 is inserted into the sliding groove of the pick 82, and the other end of the pin 81 is inserted into the positioning hole of the conical member 24.

When the conical member 24 moves, the pin 81 is driven to move synchronously, and the pin 81 drives the shifting piece 82 to rotate relative to the sensor seat 83 and simultaneously drives the shaft on the position sensor for detecting the angle change to rotate. So that the position sensor can obtain the distance moved by the cone 24 according to different changing angles, or the position sensor can obtain different positions of the cone 24 according to different angle positions, thereby obtaining the coupling state of the clutch. The specific structure of the position sensor and the method of obtaining the moving distance of the conical member 24 according to different angle changes or obtaining the different positions of the conical member 24 according to different angle positions are in the prior art, and therefore will not be described herein.

And the guiding position-limiting element 94 is fixedly connected to the first housing 11 by means of a screw connection or a welding, preferably a screw connection. The position of the guide limit 94 relative to the first housing 11 is fixed, while the guide limit 94 limits the rotation of the cone 24 relative to the axis. So that the limit projection of the cone 24 can slide only in the limit groove of the guide limit piece 94.

Further, in order to improve the accuracy of the movement of the pin 81 and the accuracy of the position information acquired by the sensor, the clutch executing device further includes a first limiting member 91.
