[0027] The embodiment of the present application provides at least one of a clutch and a vehicle, and the embodiment of the present application may not limit the specific type of the clutch.

[0028] Reference Figure 1 , shows a schematic structural diagram of a clutch described in the present application, wherein the clutch may at least include: a transmission shaft 1 and a clutch assembly 2 sleeved on the transmission shaft 1; the transmission shaft 1 includes a liquid channel 3 that penetrates the transmission shaft 1 along a first direction 4, and the liquid channel 3 is used for flowing working liquid; at least one first through hole 31 is provided on the inner wall of the liquid channel 3, and the first through hole 31 is connected to the clutch assembly 2, and the first through hole 31 is used to throw the working liquid into the clutch assembly 2 when the transmission shaft 1 rotates.

[0029] In an embodiment of the present application, a clutch is provided, and the clutch may at least include a transmission shaft 1 and a clutch assembly 2 sleeved on the outside of the transmission shaft 1; a liquid channel 3 is provided in the transmission shaft 1, and at least one first through hole 31 is provided on the inner wall of the liquid channel 3, and the first through hole 31 is connected to the clutch assembly 2. When the clutch is in a working state, the transmission shaft 1 is in a rotating state, and the centrifugal force generated by the rotation throws the working liquid in the liquid channel 3 into the clutch assembly 2 through the first through hole 31, which plays a lubricating or braking role. In the specific application of the present application, since the working liquid is transported to the clutch assembly through the liquid channel 3 and the first through hole 31 provided inside the transmission shaft, it is avoided to provide a through hole outside the clutch assembly to add the working liquid, thereby enhancing the overall structural strength of the clutch and reducing the risk of leakage of the working liquid. Specifically, the working liquid described in the embodiment of the present application may be one of the lubricating oils.

[0030] Optionally, there are at least two first through holes 31 described in the present application, and the first through holes 31 are symmetrically arranged on the inner wall of the liquid channel 3 .

[0031] In the embodiment of the present application, at least two first through holes 31 are symmetrically distributed on the inner wall of the liquid channel 31, ensuring that the working liquid thrown out through the first through holes 31 during the rotation of the transmission shaft 1 can evenly enter the clutch assembly 2, while ensuring the stability of the transmission shaft 1 during the rotation. In addition, the first through holes 31 can be evenly distributed on the transmission shaft 1 along the first direction 4 and on a plane perpendicular to the first direction 4, so as to achieve uniform throwing of the working liquid into the clutch assembly.

[0032] Optionally, the transmission shaft 1 described in the present application includes a first end 11 and a second end 12 that are separated along a first direction 4, the liquid channel 3 includes a liquid inlet channel 33 close to the second end 12 and a liquid ejection channel 32 close to the first end 11, and the first through hole 31 is arranged on the liquid ejection channel 32; the inner diameter of the liquid ejection channel 32 is larger than the inner diameter of the liquid inlet channel 33.

[0033] In the embodiment of the present application, a liquid inlet channel 33 and a liquid ejection channel 32 are provided in the liquid channel 3, and the inner diameter of the liquid ejection channel 32 is larger than that of the liquid inlet channel 33. During the rotation of the transmission shaft 1, the liquid inlet channel 33 with a smaller inner diameter allows the introduced working liquid to smoothly enter the liquid ejection channel 32, and the liquid ejection channel 32 with a larger inner diameter allows the working liquid entering the liquid ejection channel 32 to obtain a greater centrifugal force, and the effect of being ejected into the clutch assembly 2 is more stable. In addition, the first end 11 of the transmission shaft 1 is generally provided with a connecting disk, which is connected to the engine output disk through the connecting disk to drive the transmission shaft 1 to rotate, and then transmit the power generated by the engine to the target component; further, a plurality of tooth structures can be provided on the connecting disk, and the tooth structures are circumferentially distributed around the connecting disk; further, a groove can be provided on the inner side of the tooth structure, which is engaged with the engine output disk through the groove to provide a more stable power output.

[0034] Optionally, the inner diameter of the liquid-throwing channel 32 described in the present application at the middle along the axis is larger than the inner diameter at both ends of the liquid-throwing channel 32; and the middle of the liquid-throwing channel 32 to both ends of the liquid-throwing channel 32 are all gradually connected.

[0035] In the embodiment of the present application, the inner diameter of the middle part of the liquid-throwing channel 32 can be larger than the inner diameters at the two ends of the liquid-throwing channel 32, and the connection between the middle part of the liquid-throwing channel 32 and the two ends of the liquid-throwing channel 32 is gradual, that is, the inner diameter of the connection part from the middle part of the liquid-throwing channel 32 to the two ends gradually decreases, so that the working liquid in the middle part obtains a greater centrifugal force, thereby achieving a better liquid-throwing effect.

[0036] Optionally, the liquid channel 3 described in the present application also includes a gradual channel 34, which is arranged between the liquid inlet channel 33 and the liquid ejection channel 32, and the gradual channel 34 connects the liquid inlet channel 33 and the liquid ejection channel 32; and along the direction from the liquid inlet channel 33 to the liquid ejection channel 32, the inner diameter of the gradual channel 34 gradually increases.

[0037] Specifically, in the embodiment of the present application, a cylindrical channel may be further provided between the liquid-spinning channel 32 and the gradual channel 34 to connect the gradual channel 34 to the liquid-spinning channel 32; the gradual channel 34 has an inner diameter that gradually increases along the direction from the second end 12 to the first end 11 in the first direction 4, presenting a hollow truncated cone structure. In application, by providing a gradual channel 34 with a gradually increasing inner diameter between the liquid-spinning channel 32 and the liquid inlet channel 33, the working liquid that enters the liquid-spinning channel 33 through the liquid inlet channel 33 can enter the liquid-spinning channel 32 more evenly, avoiding a large difference between the two, which causes the working liquid to not evenly enter the liquid-spinning channel 32 and then not evenly enter the clutch assembly 2.

[0038] Optionally, the liquid inlet channel 33 described in the present application is provided with an opening on one side close to the second end 12, and the opening is connected to a liquid storage cylinder; the liquid storage cylinder is used to store the working liquid.

[0039] In the embodiment of the present application, the liquid inlet 33 is provided with an opening connected to a liquid storage cylinder for storing working liquid, which is used to provide or recover the working liquid in the clutch. Specifically, the liquid storage cylinder can also be a working liquid providing device installed in the vehicle, which is used to provide working liquid; during the application process, the clutch assembly 2 of the clutch will generate heat in the working state, so the liquid storage cylinder and the working liquid providing device can also be provided with a working liquid recovery circulation component, which is used to recycle the working liquid in the clutch, and take away the heat generated by the clutch during operation through the recovery circulation of the working liquid, so as to avoid overheating and damage to the clutch.

[0040] Optionally, the clutch assembly 2 described in the present application may include at least: a fixed part 21, an output part 22, and a friction component 23; the fixed part 21 and the output part 22 are sequentially sleeved on the transmission shaft 1 along the first direction 4; the friction component 23 is at least partially arranged between the fixed part 21 and the output part 22, and the friction component 23 is used to transmit the power of the transmission shaft 1 to the output part 22.

[0041] In the embodiment of the present application, the clutch assembly 2 may at least include a fixed portion 21, an output portion 22, and a friction component 23. The fixed portion 21 is used to fix the clutch to the transmission assembly outside the clutch. At least a friction component 23 is provided between the fixed portion 21 and the output portion 22. The friction component 23 is used to transmit the power of the transmission shaft 1 to the output portion 22, and then transmit the power to the external component through the output portion 22. In a specific application, the fixed portion 21 may be fixedly connected to the external transmission assembly by a plurality of bolts, screws and other fixings, and the transmission shaft 1 passes through the fixed portion 21 and the output portion 22; the output portion 22 and the fixed portion 21 may also enclose a certain cavity, and the friction component 23 is installed in the cavity; further, a bearing structure may be provided between the fixed portion 21 and the output portion 22, so that the fixed portion 21 and the output portion 22 can move relative to each other; further, the fixed portion 21 may also be provided with at least one positioning pin. In addition, during the specific installation process, the fixing part 21 is positioned to a position where it is fixedly connected to the external gearbox by means of positioning pins, and the fixing part is fixedly connected to the external gearbox by means of positioning components such as bolts and screws.

[0042] In this embodiment, the fixing part 21 , the friction part 22 and the output part 23 are used to enable the clutch to stably output power to corresponding parts.

[0043] Optionally, at least one of the output part 22 and the fixed part 21 described in the present application is provided with at least one second through hole 24, one end of the second through hole 24 is connected to the first through hole 31, and the other end is connected to the friction component 23; the second through hole 24 is used to introduce the working fluid thrown out of the first through hole 31 into the friction component 23.

[0044] In the embodiment of the present application, the at least one second through hole provided on at least one of the output portion 22 and the fixed portion 21 may be provided in multiple rows and evenly distributed on the surface of at least one of the output portion 22 and the fixed portion 21, forming an evenly distributed grid-like through hole array. In a specific application, the working liquid ejected from the first through hole 31 is evenly introduced into the friction component 23 through the second through hole 24 connected to the first through hole 31 and the friction component 23, so that the working liquid plays a role in the friction component 23.

[0045] Optionally, the output part 22 described in the present application is movably connected to the transmission shaft 1 , and the output part 22 is rotatably sleeved on the transmission shaft 1 .

[0046] In the embodiment of the present application, the output portion 22 is movably connected to the transmission shaft 1 so that the output portion 22 and the transmission shaft 1 can rotate relative to each other, so that the clutch can perform a braking function as needed during operation.

[0047] Optionally, the clutch described in the present application includes at least a braking state and a non-braking state; the friction component 23 may include multiple friction plates, multiple friction steel plates and multiple wave springs, the friction plates and friction steel plates are alternately arranged, the friction steel plates are connected to the inner wall of the fixed part, and the friction plates are fixedly connected to the outer wall of the output part; a wave spring is arranged between a friction steel plate and a friction plate; when the clutch is in the braking state, the friction steel plates abut against the friction plates, so that the wave spring is in a compressed state; when the clutch is in the non-braking state, the friction steel plates are no longer abutted against the friction plates, and the wave springs are restored to allow a gap between the friction plates and the friction steel plates.

[0048] In the embodiment of the present application, the friction component 23 may include a plurality of friction plates and a plurality of friction steel plates, and the friction plates and friction steel plates are arranged alternately and correspondingly, one friction plate corresponds to one friction steel plate, and the friction steel plate is meshed and connected with the inner wall of the fixing part 21. When the clutch is in the braking state, the friction plate and the friction steel plate contact to generate friction force, and the wave spring is compressed at the same time. At this time, there is no relative movement between the friction steel plate and the friction plate, and the relative movement between the output part 22 and the friction plate stops, completing the braking function of the clutch. When the clutch is in the non-braking state, the wave spring is restored to generate a gap between the friction steel plate and the friction plate; the wave spring makes the friction plate and the friction steel plate of the clutch not combined and the clutch does not play the braking function, so that a smaller drag torque is generated, thereby making the clutch consume less energy.

[0049] In addition, a return spring, a limit spring and a brake piston may be provided between the fixed part 21 and the output part 22. One end of the return spring is connected to the fixed part 21, and the other end is connected to the brake piston. A liquid cavity may be provided between the brake piston and the inner wall of the fixed part 21. The liquid cavity contains working liquid. The return spring, the brake piston and the limit spring are used to reset the friction steel plate and the friction plate. When the clutch is in the braking state, high-pressure liquid is injected into the liquid cavity to compress the return spring. At the same time, the friction steel plate and the friction plate are in contact, eliminating the relative movement between the two, and achieving a braking effect; when in the non-braking state, the high-pressure liquid is withdrawn, the return spring drives the friction steel plate to reset, and the wave spring drives the friction plate to reset. At this time, a gap appears again between the friction steel plate and the friction plate, and the two parts move relative to each other. When the clutch does not need to brake, the clutch consumes less energy.

[0050] Optionally, a planetary gear 5 is provided on the side of the output part 22 described in the present application away from the fixed part 21, one side of the planetary gear 5 is connected to the output part 22, and the other side of the planetary gear 5 is connected to a gearbox, and the planetary gear is used to output the power of the output part 22 to the gearbox.

[0051] In the embodiment of the present application, the second end 12 of the transmission shaft is provided with a planetary gear 5, and the power of the output part 22 is transmitted to the gearbox through the planetary gear structure. Specifically, due to the multiple gear transmission structure of the planetary gear 5, the sun gear connected to the output part 22 at the center drives the surrounding planetary gears to operate, thereby realizing the speed reduction transmission; the planetary gear 5 is small in size, light in weight, compact in structure, has large transmission power, and high load-bearing capacity, which greatly improves the performance and service life of the clutch.

[0052] It should be noted that, in practical applications, those skilled in the art can select single planetary gear row, double planetary gear row or other types of planetary gears according to actual needs, and no specific limitation is made in the embodiments of the present application.

[0053] Specifically, the clutch described in the present application is also provided with a shift fork, which is connected to the clutch shift handle and is used to fluctuate the speed change wheel to change the output / input speed ratio of the gearbox to achieve clutch shifting. On the other hand, the present application also proposes a vehicle, which includes any one of the above-mentioned clutches.

[0054] It should be noted that in the embodiment of the present application, the specific structure of the clutch is the same as the structure of the clutch in the above embodiments, and its beneficial effects are similar, which will not be repeated here. In the embodiment of the present application, the structural strength of the clutch in vehicle use is enhanced, and the user experience is improved.
