It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0038] It should be understood that the reference to "some embodiments" throughout the specification means that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present invention. Therefore, the "in some embodiments" appearing in various places throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0039] The following describes in detail a clutch, a shifting device and a vehicle provided by the utility model by listing specific embodiments.

[0040] Reference Figure 1 and Figure 2 The clutch provided by the utility model comprises: a clutch body 1; a housing, in which a guide channel 2 is arranged; a guide shaft 3, the guide shaft 3 is fixedly connected to the clutch body 1, and the guide shaft 3 is slidably connected to the guide channel 2.

[0041] Specifically, if Figure 1 and Figure 2 As shown, the clutch separation or engagement depends on the movement of the clutch body 1. The movement of the clutch body 1 causes the clutch release bearing to squeeze the diaphragm spring on the clutch to achieve clutch separation, and then the rebound force of the diaphragm spring causes the clutch body 1 to move in the opposite direction to achieve clutch engagement. A guide channel 2 is provided in the clutch housing. The guide channel 2 is arranged along a first direction. The first direction is as shown in FIG. Figure 1 and Figure 2As shown in the X direction in the figure, the first direction continues to apply in subsequent embodiments. The guide shaft 3 is fixedly connected to the clutch body 1 by fasteners 30 such as screws, bolts, rivets, etc. The guide shaft 3 is inserted into the guide channel 2 and is slidably connected to the guide channel 2. During the movement of the clutch body 1, the guide shaft 3 will be driven to move synchronously, so that the guide shaft 3 slides in the guide channel 2. The guide channel 2 plays a guiding and limiting role in the movement of the guide shaft 3, so that the guide shaft 3 can only move in the direction arranged by the guide channel 2, that is, the first direction movement. The force of the guide channel 2 on the guide shaft 3 acts on the clutch body 1, so that the clutch body 1 can only move in the direction arranged by the guide channel 2, thereby playing a guiding and limiting role on the clutch body 1, avoiding the occurrence of deviation, shaking, etc. during the movement of the clutch body 1, and improving the stability of the movement of the clutch body 1, thereby ensuring the separation or engagement effect of the clutch.

[0042] The clutch of the utility model comprises a clutch body 1, a housing and a guide shaft 3, wherein a guide channel 2 is arranged in the housing, and the guide shaft 3 is fixedly connected to the clutch body 1 and slidably connected to the guide channel 2. Thus, the sliding of the guide shaft 3 in the guide channel 2 plays a guiding and limiting role on the movement direction of the clutch body 1, thereby avoiding the occurrence of deviation, shaking and the like during the movement of the clutch body 1, improving the stability of the movement process of the clutch body 1, and thus ensuring the separation or engagement effect of the clutch.

[0043] Optionally, the guide channel 2 includes at least one axial hole, and the guide shaft 3 is inserted into the axial hole and is slidably connected to the axial hole.

[0044] Specifically, the guide channel 2 is in the form of an axial hole, including at least one axial hole, and the guide shaft 3 is inserted into the axial hole and is slidably connected with the axial hole. It is understandable that the diameter of the guide shaft 3 needs to be slightly smaller than the diameter of the axial hole, and the length of the guide shaft 3 needs to be shorter than the length of the axial hole to ensure that the guide shaft 3 can slide smoothly in the axial hole. In some embodiments, the inner wall of the axial hole is provided with a slide groove, and the outer wall of the guide shaft 3 is provided with a slide rail, and the slide rail is embedded in the slide groove and cooperates with the slide groove, so as to achieve the sliding connection between the guide shaft 3 and the axial hole. In other embodiments, the inner wall of the axial hole is provided with a ball with a smaller diameter, and the ball is arranged along the first direction, the guide shaft 3 is inserted into the axial hole, and the outer wall of the guide shaft 3 abuts against the ball, so as to achieve the sliding connection between the guide shaft 3 and the axial hole.

[0045] Optionally, refer to Figure 2 There is one shaft hole, and an escape area 21 is formed on the shaft hole. The hole wall of the escape area 21 is hollowed out so that the guide shaft 3 can slide in the shaft hole.

[0046] Specifically, in some embodiments, the guide channel 2 includes an axial hole, the inner wall of the axial hole is provided with a slide groove, a ball bearing and other structures, and an avoidance area 21 is provided on the axial hole, and the hole wall of the avoidance area 21 is partially hollowed out, so that the guide shaft 3 is fixedly connected with the clutch body 1 through the avoidance area 21. At the same time, along the first direction, the avoidance area 21 needs to have a sufficient length so that the guide shaft 3 can slide smoothly in the axial hole. In this embodiment, the setting structure of an axial hole is simple, the processing difficulty is low, and the processing efficiency is high.

[0047] Optionally, there are two axial holes, the two axial holes are spaced apart, and the axial dimension of the guide shaft 3 is greater than the spacing between the two axial holes.

[0048] Specifically, in some embodiments, the guide channel 2 includes two shaft holes, the inner walls of the two shaft holes are provided with structures such as slide grooves and balls, the two shaft holes are arranged at intervals, and the ends of the guide shaft 3 are respectively inserted into the two shaft holes. Along the first direction, the sum of the length of the two shaft holes and the spacing between the two shaft holes needs to be greater than the length of the guide shaft 3 to ensure that the guide shaft 3 can slide smoothly in the shaft hole. At the same time, the length of the guide shaft 3 needs to be greater than the spacing between the two shaft holes to avoid the guide shaft 3 from being separated from the shaft hole and falling off during the sliding process in the two shaft holes. When the guide shaft 3 moves to contact the bottom of any shaft hole, the guide shaft 3 can no longer move, so that the length and spacing of the two shaft holes can be reasonably set according to the movement range of the clutch body 1, so as to avoid the clutch body 1 from not moving in place or moving too much. The setting of the two shaft holes in this embodiment can shorten the length of each shaft hole to a certain extent, thereby reducing the difficulty of the design requirements for the shell.

[0049] Optionally, there are multiple shaft holes, two of which are main shaft holes, and the remaining shaft holes are auxiliary shaft holes, and the guide shaft 3 is slidably connected to the main shaft holes.

[0050] Specifically, in some embodiments, the guide channel 2 includes a plurality of shaft holes, the plurality of shaft holes are arranged at intervals, the guide shafts 3 are respectively inserted into the plurality of shaft holes, and along the first direction, the sum of the lengths of the plurality of shaft holes and the intervals therebetween needs to be greater than the length of the guide shaft 3, so as to ensure that the guide shaft 3 can slide smoothly in the plurality of shaft holes. Two shaft holes among the plurality of shaft holes are main shaft holes, and the remaining shaft holes are auxiliary shaft holes. The inner wall of the main shaft hole may be provided with structures such as a slide groove and a ball bearing to realize the sliding connection between the guide shaft 3 and the main shaft hole. The inner wall of the auxiliary shaft hole may not be provided with any structure, and the auxiliary shaft hole mainly plays a role in supporting and positioning the guide shaft 3, thereby improving the stability of the guide shaft 3 during the sliding process.

[0051] Optionally, refer to Figure 2 The clutch further includes: a bushing 4 , which is arranged on at least a portion of the inner wall of the guide channel 2 , and the guide shaft 3 is passed through the bushing 4 .

[0052] Specifically, the bushing 4 is arranged on at least part of the inner wall of the guide channel 2. The bushing 4 can be made of wear-resistant bushings 4 made of iron, copper, engineering plastics, etc. In one embodiment, the bushing 4 can be spread all over the inner wall of the guide channel 2, and the guide shaft 3 is inserted into the bushing 4, which has a better limiting effect on the guide shaft 3. In another embodiment, the bushing 4 can be arranged at the opening of the guide channel 2, which can not only have a limiting effect on the guide shaft 3 and prevent the guide shaft 3 from sliding out of the guide channel 2, but also save materials and processing costs. Those skilled in the art can freely set the setting position of the bushing 4 according to actual needs, and this embodiment is not limited to this. In addition, in the case of vibration during the movement of the clutch body 1, the bushing 4 can also play a role of buffering and shock reduction on the clutch body 1 through the guide shaft 3, further improving the stability of the movement of the clutch body 1.

[0053] Optionally, refer to Figure 2 At least part of the inner wall of the guide channel 2 is provided with a slot 22 , and the bushing 4 is clamped in the slot 22 .

[0054] Specifically, at least part of the inner wall of the guide channel 2 is provided with a slot 22, and the inner diameter of the guide channel 2 at the position where the slot 22 is provided is slightly larger than the inner diameter of other positions. The bushing 4 is clamped in the slot 22, and the slot 22 has a certain axial limiting effect on the bushing 4, which can prevent the bushing 4 from axial movement under the influence of the guide shaft 3, thereby ensuring the reliable installation of the bushing 4.

[0055] Optionally, the guide shaft 34 includes at least two shaft segments, and at least two of the shaft segments are fixedly connected to form the guide shaft 34 .

[0056] Specifically, in order to facilitate the installation of the guide shaft 34, the guide shaft 34 can be set as a split structure, including at least two shaft sections, and at least two shaft sections are fixedly connected together to form the guide shaft 34. In the first embodiment, a mounting hole can be set on each shaft section, and the shaft sections are sequentially connected together by fasteners such as pins to form a complete guide shaft 34. In the second embodiment, an extension with a smaller diameter can be set at the end of a shaft section, and a shaft hole can be set at the end of the shaft section connected thereto, and the extension is penetrated in the shaft hole to realize the fixed connection of the two shaft sections, so that the shaft sections are sequentially connected together to form a complete guide shaft 34. In the third embodiment, a plurality of elastic protrusions can be set at the end of a shaft section, and a plurality of positioning holes can be set at the end of the shaft section connected thereto, and a plurality of elastic protrusions can be clamped in the plurality of positioning holes to realize the fixed connection of the two shaft sections, so that the shaft sections are sequentially connected together to form a complete guide shaft 34. Those skilled in the art can freely set the connection method of the shaft sections, and this embodiment does not limit this.

[0057] Optionally, refer to Figures 1 to 3 The clutch body 1 includes a shift fork 11 and an execution push rod 12; the shift fork 11 is fixedly connected to the guide shaft 3, and the shift fork 11 has an execution groove 110, and the execution groove 110 is arranged in a direction parallel to the guide channel 2; the execution push rod 12 is arranged in the execution groove 110, and one end of the execution push rod 12 extends to the outside of the execution groove 110, which is used to push the clutch rocker arm to achieve the separation or engagement of the clutch.

[0058] Specifically, if Figure 1 and Figure 2 As shown, the clutch body 1 includes a shift fork 11 and an actuator push rod 12. The shift fork 11 is fixedly connected to the guide shaft 3. The guide shaft 3 and the shift fork 11 can be an integrally formed structure, or the guide shaft 3 and the shift fork 11 can be assembled and connected together by fasteners such as pins and bolts. The specific connection form is not limited in this embodiment. The shift fork 11 is used to shift the synchronizer gear ring to achieve the speed change of the vehicle. The shift fork 11 has an actuator groove 110, and the actuator groove 110 is arranged in a direction parallel to the guide channel 2. An actuator push rod 12 is arranged in the actuator groove 110. One end of the actuator push rod 12 abuts against the bottom of the actuator groove 110, and the other end extends to the outside of the actuator groove 110, which is used to push the clutch rocker arm to achieve the separation or engagement of the clutch. Specifically, when the clutch is disengaged, the vehicle's control system issues a shift command, and the drive structure starts to drive the shift fork 11 to move, so that the bottom of the execution groove 110 on the shift fork 11 starts to push the execution push rod 12 to move synchronously, push the execution push rod 12 outward, and squeeze the clutch diaphragm spring through the clutch rocker arm, pushing the clutch to disengage; when the clutch is engaged, the drive mechanism 5 drives the shift fork 11 to move in the opposite direction, the execution groove 110 on the shift fork 11 starts to retreat, and the rebound force of the clutch diaphragm spring reversely squeezes the clutch rocker arm, thereby pushing the execution push rod 12 to retreat inward until it retracts into the execution groove 110, thereby achieving the engagement of the clutch. During the movement of the shift fork 11, the guide shaft 3 moves synchronously in the guide channel 2, so that the guide channel 2 plays a guiding and limiting role on the shift fork 11, so that the shift fork 11 moves in a direction parallel to the guide channel 2, avoiding the shift fork 11 from deflecting under the action of gravity or shaking under the condition of vehicle bumps, improving the stability of the movement of the shift fork 11, and then improving the stability of the movement of the actuator push rod 12, ensuring that the actuator push rod 12 accurately abuts against the clutch rocker arm, and realizing effective separation or engagement of the clutch. In a preferred embodiment, as Figure 1 and 3As shown, a detection component 13, such as a position sensor, a magnetic induction sensor, etc., can be provided on the fork 11. The detection component 13 can detect the movement position of the fork 11. When the fork 11 moves to the target position, the driving mechanism 5 is controlled to stop the action, so that the fork 11 stops moving, thereby ensuring the accuracy of clutch separation or engagement. The above-mentioned target position refers to the position of the fork 11 when the clutch is just separated or engaged.

[0059] Optionally, refer to Figure 2 and Figure 4 The clutch further includes: a turbine 61 and a worm 62; the turbine 61 is meshed with the worm 62, and the worm 62 is fixedly connected to the shift fork 11; the turbine 61 drives the worm 62 to move in a direction parallel to the guide channel 2 to drive the shift fork 11 to move synchronously.

[0060] Specifically, the clutch body 1 is driven by a worm gear mechanism, such as Figure 2 and 4 As shown, the turbine 61 is meshed with the worm 62, the worm 62 is fixedly connected to the fork 11, a shift block 63 is fixedly connected to the worm 62, the worm 62 is fixedly connected to the fork 11 through the shift block 63, the drive mechanism 5 is energized to rotate the turbine 61, the turbine 61 rotates to drive the worm 62 to move in a direction parallel to the guide channel 2, and the shift fork 11 is driven to move in a direction parallel to the worm 62 through the shift block 63. Of course, the worm 62 needs to be arranged in a direction parallel to the guide channel 2 before it can move in a direction parallel to the guide channel 2. On the basis of the guide shaft 3 on the lower side of the fork 11 sliding in the guide channel 2 for guidance, this embodiment adds guidance on the upper side of the fork 11, thereby further improving the stability of the movement process of the push rod 12.

[0061] Optionally, refer to Figure 2 The clutch also includes an actuator 7; the actuator 7 is arranged at the bottom of the actuator groove 110, and a spherical concave surface 70 is provided on the side of the actuator 7 close to the actuator push rod 12; one end of the actuator push rod 12 is in contact with the spherical concave surface 70, and the other end extends to the outside of the actuator groove 110.

[0062] Specifically, if Figure 2As shown, the actuator 7 is arranged at the bottom of the actuator groove 110. The actuator 7 and the fork 11 can be an integrally processed structure or an assembled and connected structure. A spherical concave surface 70 is provided on the side of the actuator 7 close to the actuator push rod 12. One end of the actuator push rod 12 abuts against the spherical concave surface 70, and the other end extends to the outside of the actuator groove 110, which is used to push the clutch rocker arm to achieve separation or engagement of the clutch. Since the end of the actuator push rod 12 extending to the outside of the actuator groove 110 is hinged with the clutch rocker arm, under the action of the rocker arm, the end of the actuator push rod 12 will be subjected to a certain rotational extrusion force, which will cause the side of the actuator push rod 12 abutting against the actuator 7 to produce a slight rotation. At the same time, during the actual movement of the actuator push rod 12, the end of the actuator push rod 12 may also be slightly tilted under the action of gravity. Therefore, in order to ensure the smooth movement of the actuator push rod 12, a spherical concave surface 70 is set on the side of the actuator 7 close to the actuator push rod 12, so that the end of the actuator push rod 12 has a certain amount of activity margin, ensuring that the force transmission between the actuator push rod 12 and the clutch rocker arm can be smoothly realized. In addition, a pressure plate 8 is set at the opening of the actuator groove 110, and a through hole is opened on the pressure plate 8. The actuator push rod 12 passes through the through hole and extends to the outside of the actuator groove 110. The pressure plate 8 can prevent the actuator push rod 12 from detaching from the actuator groove 110 during the movement process, ensuring the reliability of the movement process of the actuator groove 110.

[0063] The utility model also provides a shifting device, comprising the clutch described in any one of the above items.

[0064] Specifically, the gear shifting device includes an engine, a gearbox and the aforementioned clutch, etc. The clutch has good stability when working, and can still ensure effective separation or engagement of the clutch under conditions of vehicle bumps and shakes, thereby realizing the cutting off and transmission of power between the engine and the gearbox. Gear shifting can be performed when the power between the engine and the gearbox is cut off, thereby ensuring the reliability of the gear shifting device.

[0065] The utility model also provides a vehicle, comprising the above-mentioned gear shifting device.

[0066] Specifically, the vehicle can be a fuel vehicle or a new energy vehicle, and is equipped with the aforementioned shifting device, which has high shifting reliability and improves the safety of vehicle use.
