[0045] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] First, refer to Figures 1 to 7 As shown, the present invention provides a clutch for realizing power transmission and disconnection between a power input member 10 and a power output member 20 .

[0047] In a fuel vehicle model, the power input 10 is connected to the engine (not shown) in a transmission manner, and the power output 20 is connected to the differential of the wheel (not shown). After the power input 10 and the power output 20 are combined, the power output of the engine is transmitted to the differential via the power input 10 and the power output 20.

[0048] In a hybrid vehicle model, the power input member 10 is connected to the engine in a transmission manner, the power output member 20 is connected to the differential of the wheels, and the power output member 20 is connected to the differential drive motor (not shown). The power of the differential drive motor can be transmitted to the differential through the power output member 20. When it is necessary to switch to using the engine output power or the engine and the differential drive motor to work together, the power input member 10 can be combined with the power output member 20, and the power output of the engine is transmitted to the differential via the power input member 10 and the power output member 20.

[0049] Reference Figures 1 to 7 As shown, the clutch further includes a locking mating member 30 and a locking member 40, wherein:

[0050] The power output member 20 rotates around the preset axis 21. In a feasible embodiment, the power output member 20 is a shaft structure, which is rotatably arranged between two bearing seats. The preset axis 21 is the central axis of the shaft structure. A first cavity 22 is formed in the power output member 20. The first cavity 22 is located in the radial direction of the preset axis 21. The extension direction of the first cavity 22 extends along the radial direction of the preset axis 21. The first cavity 22 is formed with an opening on the outer peripheral surface of the power output member 20.

[0051] The locking mating part 30 and the power input part 10 are formed separately and can be detachably connected or integrally formed. The power of the engine is transmitted to the power input part 10, driving the power input part 10 to rotate around its own axis. The locking mating part 30 is arranged on the outside of the power output part 20. In a feasible embodiment, the locking mating part 30 is an annular structure, and the power output part 20 extends into the annular structure. A second cavity 31 is formed in the locking mating part 30, and the second cavity 31 is located in the radial direction of the preset axis 21. The second cavity 31 forms an opening at least on the surface facing the power output part 20.

[0052] The locking member 40 is movably arranged in the first cavity 22 or the second cavity 31. Preferably, there are multiple locking members 40, multiple first cavities 22 and multiple second cavities 31. During the power transmission process, multiple locking members 40, multiple first cavities 22 and multiple second cavities 31 are arranged in a one-to-one correspondence to evenly transmit torque.

[0053] in:

[0054] When the locking member 40 is located at the starting end of the moving path, that is, when the power connection between the power input member 10 and the power output member 20 is disconnected, the locking member 40 is located in the first cavity 22 or the second cavity 31, and the power input member 10 and the power output member 20 move independently without power transmission between them.

[0055] In a fuel vehicle model, when the clutch needs to realize power transmission between the power input part 10 and the power output part 20, in the initial state, the power output part 20 remains stationary, the power input part 10 rotates under the drive of the engine, and the locking part 40 is driven by external force to move. When the locking part 40 is at the end of the moving path, the locking part 40 is simultaneously located in the first cavity 22 and the second cavity 31. The rotation of the power input part 10 drives the locking part 40 to simultaneously abut the inner wall surfaces of the first cavity 22 and the second cavity 31, thereby realizing the synchronous rotation of the power input part 10 and the power output part 20.

[0056] In a hybrid vehicle model, when the clutch needs to realize power transmission between the power input member 10 and the power output member 20, in the initial state, the power output member 20 is driven to rotate by the differential drive motor, and the power input member 10 is rotated under the drive of the engine. The speed difference between the power input member 10 and the power output member 20 is controlled within a certain range, for example, the speed difference is controlled within 100 rpm, and the locking member 40 begins to be driven by an external force to move. When the locking member 40 is at the end of the moving path, the locking member 40 is simultaneously located in the first cavity 22 and the second cavity 31. The rotation of the power input member 10 drives the locking member 40 to simultaneously abut the inner wall surfaces of the first cavity 22 and the second cavity 31, thereby realizing the synchronous rotation of the power input member 10 and the power output member 20.

[0057] In summary, the locking member 40 realizes the power transmission and disconnection of the clutch by moving in the radial direction of the preset axis 21 of the power output member 20, thereby reducing the axial space occupied by the clutch and facilitating the shaft arrangement of the transmission system.

[0058] In the embodiment provided by the present invention, there are various arrangements and driving modes of the locking member 40. Two modes are listed below for illustration. Those skilled in the art will appreciate that more variations can be made based on the following embodiments.

[0059] Example 1

[0060] Reference Figures 1 to 6 As shown, this is a first arrangement and driving mode of the locking member 40. Specifically, a third cavity 23 is provided in the power output member 20. The third cavity 23 is located in the axial direction of the preset axis 21. The third cavity 23 extends along the axial direction of the preset axis 21. The third cavity 23 is connected to the first cavity 22, and the locking member 40 is located in the first cavity 22.

[0061] Preferably, the locking member 40 forms a clearance fit with the first cavity 22 to guide the locking member 40 to move in the radial direction of the preset axis 21, and the cross-section of the second cavity 31 is a waist-shaped groove. The waist-shaped groove occupies a larger space, which is conducive to increasing the probability of engagement, so that during the movement of the locking member 40 from the first cavity 22 toward the second cavity 31, the locking member 40 can enter the second cavity 31 more smoothly.

[0062] In a hybrid vehicle, since the first cavity 22 and the second cavity 31 are both arranged radially, when the speed of the power output component is higher and the torque is greater, the locking member 40 tends to enter the second cavity 31 more easily under centrifugal force.

[0063] A first locking drive member 50 is provided in the third cavity 23. The first locking drive member 50 can move in the axial direction of the preset axis 21 to abut against the locking member 40. During the movement of the first locking drive member 50, a force is applied to the locking member 40 to drive the locking member 40 to move in the radial direction of the preset axis 21 and keep the locking member 40 in the locked position. The locking member 40 is simultaneously located in the first cavity 22 and the second cavity 31 to prevent the locking member 40 from retreating and causing power transmission interruption.

[0064] In a feasible embodiment, the first locking driver 50 has a driving guide portion 51 and a locking portion 52. The driving guide portion 51 is closer to the locking member 40 than the locking portion 52. The driving guide portion 51 contacts the locking member 40 earlier than the locking portion. The driving guide portion 51 is used to provide the locking member 40 with a force extending in the radial direction of the preset axis 21, thereby driving the locking member 40 to move radially until it reaches the locked position. The locking portion 52 is used to maintain the locking member 40 in the locked position, wherein:

[0065] When the first locking drive member 50 moves along the axial direction of the preset axis 21 under the action of external force, the driving guide portion 51 begins to contact the locking member 40, and the driving guide portion 51 and the locking member 40 form a driving guide fit, applying a force extending in the radial direction of the preset axis 21 to the locking member 40 to drive the locking member 40 to move along the radial direction of the preset axis 21.

[0066] When the first locking drive member 50 moves to the end of the moving path, the locking portion 52 forms a locking fit with the locking member 40 to lock and retain the locking member 40 in the first cavity 22 and the second cavity 31, thereby realizing power transmission between the power input member 10 and the power output member 20.

[0067] Reference Figure 2 、 Figure 4 as well as Figure 6As shown, the driving guide portion 51 is a driving guide inclined surface formed on the outer surface of the first locking driving member 50. The extending direction of the driving guide portion 51 intersects with the axial direction of the preset axis 21. A certain angle is formed between the driving guide portion 51 and the preset axis 21. Therefore, when the first locking driving member 50 abuts against the locking member 40, the force of the first locking driving member 50 is decomposed into a radial component extending in the radial direction of the preset axis 21 and an axial component extending in the axial direction of the preset axis 21. At the same time, since the locking member 40 is a clearance fit in the first locking driving member 50, the driving guide portion 51 is a clearance fit in the first locking driving member 50. The radial component of force in the cavity 22 will drive the locking member 40 to move along the radial direction of the preset axis 21 until the locking member 40 passes over the driving guide portion 51 and reaches the position where the locking portion 52 is located. Furthermore, an inclined surface is also provided on the locking member 40 to cooperate with the driving guide portion 51 to realize the transmission of the force, so that while the locking member 40 moves radially, the axial movement of the first locking driving member 50 can also be carried out smoothly, thereby avoiding the locking member 40 being unable to pass over the driving guide portion 51, and the locking member 40 being unable to reach the locked position smoothly.

[0068] The locking portion 52 is a locking surface formed on the outer surface of the first locking drive member 50. The extension direction of the locking surface is parallel to the axial direction of the preset axis 21. The locking portion 52 is connected to the drive guide portion 51. After the locking member 40 passes the drive guide portion 51, it reaches the locking portion 52. At this time, the locking member 40 reaches the locking position. Preferably, the extension direction of the end face of the locking member 40 is also parallel to the axial direction of the preset axis 21. When the locking member 40 is in the locked position, the end face of the locking member 40 abuts against the locking portion 52, so that the locking member 40 cannot retreat and reaches a self-locking state. In the self-locking state, the first locking drive member 50 can stop moving, which is beneficial to reduce energy consumption.

[0069] There are many ways to drive the first locking drive member 50 to move linearly, such as clutch drive motor drive, piston rod drive, etc. When the clutch drive motor is used for drive, the output shaft of the clutch drive motor is connected to the first locking drive member 50, and the rotation of the output shaft of the clutch drive motor is converted into the linear movement of the first locking drive member 50. During the movement, the first locking drive member 50 will abut against the locking member 40 to drive the movement of the locking member 40. If the locking member 40 is restricted from moving, the first locking drive member 50 will also be unable to move, which may cause the clutch drive motor to heat up and burn.

[0070] In order to prevent the clutch drive motor from heating up and burning due to stalling, the first locking drive member 50 is designed as a split structure. Figure 2 、 Figure 4 as well as Figure 6As shown, the first locking driving member 50 includes a first locking driving block 53, a second locking driving block 54 and a first elastic member 55, wherein:

[0071] A guide block 56 is protruded from the end of the first locking drive block 53, and the guide block 56 extends along the axial direction of the preset axis 21 to guide the movement of the second locking drive block 54. The first locking drive block 53 is transmission-connected to the output shaft of the clutch drive motor, and the rotation of the output shaft of the clutch drive motor is converted into the axial movement of the first locking drive block 53 along the preset axis 21.

[0072] The second locking drive block 54 is used to abut against the locking member 40. The driving guide portion 51 and the locking portion 52 are both provided on the second locking drive block 54. A guide groove 57 is formed in the second locking drive block 54. The guide groove 57 forms a clearance fit with the guide block 56. The second locking drive block 54 is guided and fitted on the guide block 56.

[0073] The first elastic member 55 is located between the first locking drive block 53 and the second locking drive block 54. One end of the first elastic member 55 abuts against the first locking drive block 53, and the other end of the first elastic member 55 abuts against the second locking drive block 54. The first elastic member 55 is preferably a spring, and the opposite ends of the spring abut against the end faces of the first locking drive block 53 and the second locking drive block 54 respectively.

[0074] When the first locking drive block 53 moves, the first elastic member 55 is compressed and elastically deformed to accumulate elastic force. When the accumulated elastic force reaches a certain value, the elastic force can drive the second locking drive block 54 to move. During the movement, the second locking drive block 54 abuts against the locking member 40, thereby driving the locking member 40 to move. During the movement of the locking member 40, there is a possibility that the locking member 40 and the second cavity 31 of the locking mating member 30 are misaligned, resulting in the locking member 40 being unable to continue to move. Therefore, the second locking drive block 54 is also unable to move, and the first locking drive block 53 will continue to move under the drive of the motor. The first elastic member 55 is compressed and elastically deformed to accumulate elastic force. When the accumulated elastic force reaches a certain value, the elastic force can drive the second locking drive block 54 to move. The component 55 continues to be pressurized and continues to accumulate elastic force. When the second cavity 31 of the locking fitting 30 moves to the position corresponding to the first cavity 22, the locking component 40 is no longer blocked, and the elastic force accumulated by the first elastic component 55 is applied to the second locking drive block 54, driving the second locking drive block 54 to continue to move, and the locking component 40 also moves to between the first cavity 22 and the second cavity 31. In this way, the first locking drive block 53 can continue to move without being affected by the state of the locking component 40, thereby effectively protecting the clutch drive motor and preventing the clutch drive motor from overheating or excessive current due to stalling, causing the clutch drive motor to burn out.

[0075] Further, refer to Figure 2 、 Figure 4 as well as Figure 6 As shown, in order to prevent the second locking drive block 54 from being subjected to excessive force from the first elastic member 55 and thus falling off from the guide block 56, a guide groove 57 is set through the second locking drive block 54, and the guide block 56 passes through the guide groove 57. A limiting block 58 is set at the end of the guide block 56 away from the first locking drive block 53. When the second locking drive block 54 is pushed to the limit position by the elastic force of the first elastic member 55, the second locking drive block 54 is abutted against the limiting block 58 to limit further movement of the first locking drive block 53 and prevent the second locking drive block 54 from falling off.

[0076] In a hybrid vehicle, before the power input member 10 establishes power transmission with the power output member 20, the power output member 20 has already been rotated by the drive of the differential drive motor, and the locking member 40 in the first cavity 22 may fall into the second cavity 31 under the action of centrifugal force. In order to prevent the locking member 40 from entering the second cavity 31 in advance before the power input member 10 establishes power transmission with the power output member 20, in the embodiment provided by the present invention, a blocking member 70 and a second elastic member 71 are accommodated in the second cavity 31. The blocking member 70 is located at the opening of the second cavity 31. The second elastic member 71 is connected to the blocking member 70 so that the blocking member 70 can elastically reciprocate along a preset path. In a feasible embodiment, the second elastic member 71 is a spring. A support 72 is further provided in the second cavity 31. One end of the spring is fixed to the support 72, and the other end of the spring is connected to the blocking member 70. The spring provides an initial elastic force to the blocking member 70. The preset path of the blocking member 70 is the deformation path of the spring, wherein:

[0077] When the blocking member 70 is located at the starting end of the preset path, the locking member 40 can abut against the blocking member 70 during the movement. At this time, it is necessary to overcome the initial elastic force applied to the blocking member 70 by the second elastic member 71 until the blocking member 70 is driven to move along the preset path. The locking member 40 can then enter the second cavity 31. The locking member 40 cannot overcome this initial elastic force under the action of centrifugal force alone, and cannot drive the blocking member 70 to move. The locking member 40 cannot enter the second cavity 31. Only the locking member 40 driven by the first locking driving member 50 can overcome this initial elastic force.

[0078] When the blocking member 70 moves toward the support 72, the second elastic member 71 accumulates elastic force. When the blocking member 70 is at the end of the preset path, the elastic force accumulated by the second elastic member 71 reaches the maximum value, and the locking member 40 also reaches the locking position and is located in the first cavity 22 and the second cavity 31 at the same time. The end face of the locking member 40 abuts against the locking portion 52 of the first locking drive member 50, so that the locking member 40 cannot retreat and reaches a self-locking state, thereby realizing power transmission between the power input member 10 and the power output member 20.

[0079] When it is necessary to disconnect the power transmission between the power input member 10 and the power output member 20, the first locking drive member 50 moves in the direction away from the locking member 40, and the contact position between the locking member 40 and the first locking drive member 50 changes from the locking portion 52 to the driving guide portion 51. The elastic force of the second elastic member 71 is released, pushing the locking member 40 to move back along the radial direction of the preset axis 21 until the locking member 40 is completely returned to the first cavity 22, disconnecting the power transmission between the power input member 10 and the power output member 20.

[0080] Example 2

[0081] Reference Figure 7 The figure shows a second arrangement and driving method of the locking member 40. Specifically, the second cavity 31 is provided through the locking member 30. The locking member 40 is located in the second cavity 31, and at least a portion of the locking member 40 extends out of the second cavity 31. A second locking driver 60 is provided on the exterior of the locking member 30. The second locking driver 60 is an annular structure. The locking member 30 extends into the annular structure. The second locking driver 60 can move in the axial direction of the preset axis 21 to abut against the locking member 40, thereby driving the locking member 40 to move in the radial direction of the preset axis 21. When the locking member 40 is at the end of the movement path, the locking member 40 is simultaneously located in the first cavity 22 and the second cavity 31. The rotation of the power input member 10 drives the locking member 40 to abut the inner wall surfaces of the first cavity 22 and the second cavity 31, thereby achieving synchronous rotation of the power input member 10 and the power output member 20.

[0082] Furthermore, in this embodiment, a driving guide slope and a locking surface are also provided on the second locking drive member 60, and the support 72, the second elastic member 71 and the blocking member 70 are all arranged in the first cavity 22. The arrangement form, action process and working principle of the driving guide slope, locking surface, support 72, the second elastic member 71 and the blocking member 70 in this embodiment can all refer to the relevant contents of Example 1 and will not be repeated here.

[0083] In this embodiment, the locking member 40 forms a clearance fit with the second cavity 31 to guide the locking member 40 to move along the radial direction of the preset axis 21, and the cross-section of the first cavity 22 is a waist-shaped groove. The waist-shaped groove occupies a larger space, which is conducive to increasing the probability of engagement, so that when the locking member 40 moves from the second cavity 31 toward the first cavity 22, the locking member 40 can enter the first cavity 22 more smoothly.

[0084] Those skilled in the art will appreciate that, in addition to the aforementioned embodiments, the first locking driver 50 and the second locking driver 60 may also be driven by hydraulic oil or electromagnet magnetic adsorption, etc., which is not limited here.

[0085] Secondly, the utility model provides a vehicle including a gearbox, in which the aforementioned clutch is provided. The locking member 40 in the clutch realizes the power transmission and disconnection of the clutch by moving in the radial direction of the preset axis 21 of the power output member 20, thereby reducing the axial space occupied by the clutch and facilitating the shaft system arrangement of the transmission system.

[0086] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings.
