The structure and function of the solution of the present application will now be described in detail with reference to fig. 1 to 3.
The present application provides a clutch, referring to fig. 1, which includes a first rotor 1, a second rotor 2, a clutch mechanism 3 and a driving mechanism 5. The first rotor 1 is embodied as a transmission shaft, and the first rotor 1 has a connection hole extending along an axial direction, and the connection hole is used for connecting the transmission shaft of the power transmission mechanism and rotating under the driving of the transmission shaft. The second rotor 2 is rotatably sleeved on the periphery of the first rotor 1. The clutch mechanism 3 includes a first gear member 4 and a second gear member 21. In the present embodiment, a plurality of first gear teeth 41 are circumferentially and uniformly spaced on the outer periphery of the first gear member 4, and a plurality of second gear teeth 21A are circumferentially and uniformly spaced on the inner periphery of the second gear member 21. The first gear member 4 is disposed at an outer periphery of the first rotor 1, and when the first rotor 1 rotates, the first gear member 4 rotates synchronously with the first rotor 1, and specifically, the first gear member 4 is fixedly coupled to the first rotor 1 by a spline. The second gear 21 is disposed on the second rotor 2 and can rotate synchronously with the second rotor 2 when the second rotor rotates. Specifically, in the present embodiment, the second rotor 2 is integrally formed with the second gear member 21. It will be appreciated that in other embodiments the second gear member 21 may be assembled separately from the second rotor 2. In the present embodiment, the first rotor 1 transmits the rotation torque to the second rotor 2 when the first gear member 4 and the second gear member 21 are engaged, so that the second rotor 2 drives the mechanism coupled thereto to operate, and unloads the torque transmitted to the second rotor 2 when the first gear member 4 and the second gear member 21 are disengaged.
In the embodiment of the present invention, referring to fig. 1, the driving mechanism 5 is used to push the first gear member 4 to move axially. The drive mechanism 5 comprises a cylinder assembly and a resilient assembly. The cylinder assembly includes a housing 51 and a piston member 53. The housing 51 is disposed around the outer periphery of the first rotor 1, the housing 51 has an air inlet passage 52A and a sliding groove 52B communicating with the air inlet passage 52A, and the piston member 53 is disposed in the sliding groove 52B and forms an air chamber 52 with the housing 51. In the present embodiment, the air chamber 52 is formed by the air intake passage 52A and a part of the slide groove 52B. The air inlet passage 52A is communicated with the outer space of the housing 51, and is used for allowing air to enter the air chamber 52 to push the piston member 53 to move along the axial direction so as to drive the first gear member 4 to move. The elastic component includes a plurality of elastic members 6, and two ends of each elastic member 6 along the axial direction are respectively supported on the first gear member 4 and the second gear member 21.
In the embodiment of the present invention, referring to fig. 1 to 3 in combination, the piston member 53 is acted by the air pressure to push the first gear member 4 to advance to the second gear member 21 along the axial direction, so that the first gear member 4 and the second gear member 21 are switched from the meshing state to the separating state, and the first gear member 4 is compressed by the elastic member 6. When the piston member 53 is not subjected to the pushing force of the air pressure to the second gear member 21 in the axial direction, the elastic member 6 can be reset from the compressed state, and can push the first gear member 4 to move in the direction away from the second gear member 21 when being reset, and the first gear member 4 and the second gear member 21 are engaged after a first stroke preset in the movement. That is, when the first gear member 4 and the second gear member 21 are in the separated state, the first gear member 4 is supported by the pressure in the air cavity 52, and when the first gear member 4 and the second gear member 21 are in the engaged state, the first gear member 4 is engaged with the second gear member 21 under the action of the pre-tightening force of the elastic member 6, so that when the first rotor 1 transmits the rotational torque to the second rotor 2, the first gear member 4 is supported by the mechanical force of the elastic member 6 to transmit the rotational torque.
It will be appreciated that the drive mechanism 5 described above achieves that the first and second gear members 4, 21 are in an engaged condition when the clutch of the present application is in a normal state (i.e. a state in which it is not inflated into the air intake passage), and that the first and second gear members 4, 21 are in a disengaged condition when the clutch of the present application is inflated. Therefore, the clutch of this application also can not influence the stable transmission of moment of torsion under the circumstances of gas leakage, reaches to solve among the prior art because the gas leakage appears, can make first gear 4 and the unable normal meshing of second gear 21 lead to the unable technical problem of normal transmission of moment of torsion.
In the embodiment of the present invention, when the first gear member 4 and the second gear member 21 are engaged, the elastic member 6 is compressed between the first gear member 4 and the second gear member 21. That is, when the first rotor 1 normally transmits the torque to the second rotor 2, the elastic member 6 still applies a restoring force to the first gear member 4 and the second gear member 21, so that the abnormal engagement may not occur due to other external forces (e.g., a bouncing movement of the vehicle during traveling).
In an embodiment of the present invention, referring to fig. 1 and fig. 3, the second gear 21 includes a first connecting portion and a first receiving groove 22 along the axial direction according to a predetermined order.

When the first gear member 4 moves in the axial direction under the action of the air pressure, the first gear teeth 41 of the first gear member 4 enter the first receiving groove 22A in the axial direction, that is, the first receiving groove 22A receives the first gear teeth 41 when the first gear member 4 and the second gear member 21 are separated from each other. It is understood that the maximum height of the first receiving groove 22A in the axial direction is not smaller than the height of the first gear tooth 41 in the axial direction.
In the embodiment of the present invention, referring to fig. 1 and fig. 2, the first end surface of the first gear member 4 facing the second gear member 21 is provided with a plurality of second receiving grooves 42 arranged along the circumferential direction at intervals, and each of the second receiving grooves 42 is arranged at equal intervals. An elastic member 6 is disposed in each second receiving slot 42 to prevent the elastic member 6 from deflecting in the radial direction when compressed in the axial direction, which results in uneven stress on the first gear member 4 and the second gear member 21. One end of the elastic element 6 in the axial direction is supported at the bottom of the second receiving groove 42, the other end is abutted against a supporting element 24, the supporting element 24 is supported at the inner ring of the first bearing assembly 23 in the axial direction, and the supporting element 24 is located in the first receiving groove 22. The support member 24 serves to convert and uniformly apply the elastic force of each elastic member 6 to the second gear member 21.
