[0040] Nowadays, cars have entered every household as a means of transportation. At present, my country's car ownership ranks first in the world. Cars not only bring a qualitative improvement to people's lives and facilitate people's travel, but also drive economic development.

[0041] In the field of vehicle technology, clutches are widely used. They are mainly used for the separation and connection of shafts during machine operation. Traditional multi-plate friction clutches generally include friction plates, steel plates, wave springs and other components, with complex structures and high costs.

[0042] In order to solve the above technical problems, the present application provides a vehicle, which may include a frame and a clutch assembly 100, and the clutch assembly 100 is arranged on the frame.

[0043] For details, please refer to Figure 1 The present application provides a clutch assembly 100, which may include: a first rotating shaft 110, a second rotating shaft 120, a clutch outer cone 130, a clutch inner cone 140, a first driving structure and a second driving mechanism.

[0044] Among them, the first rotating shaft 110 can be the engine input shaft, the second rotating shaft 120 can be the engine output shaft, part of the second rotating shaft 120 is passed through the first rotating shaft 110, and the first rotating shaft 110 and the second rotating shaft 120 are rotationally connected through a needle bearing, and there can be two needle bearings.

[0045] The clutch outer cone 130 is sleeved on the circumferential outer side of the first rotating shaft 110 and is fixedly connected to the first rotating shaft 110. Specifically, the clutch outer cone 130 can be keyed to the first rotating shaft 110 or can be integrally formed with the first rotating shaft 110. The inner circumference of the clutch outer cone 130 is formed as a first conical surface 131. The clutch outer cone 130 includes a first position and a second position. The clutch outer cone 130 can move between the first position and the second position.

[0046] The clutch inner cone 140 is sleeved on the circumferential outer side of the second rotating shaft 120 and is fixedly connected to the second rotating shaft 120. Specifically, the clutch inner cone 140 can be keyed to the second rotating shaft 120 or formed integrally with the second rotating shaft 120. The outer circumferential surface of the clutch inner cone 140 is formed as a second conical surface 141 that cooperates with the first conical surface 131. When the clutch outer cone 130 is in the first position, the first conical surface 131 is coupled with the second conical surface 141. When the clutch outer cone 130 is in the second position, the first conical surface 131 is separated from the second conical surface 141.

[0047] Among them, a friction material layer can be provided on one of the first conical surface 131 and the second conical surface 141, and the material of the friction material layer can be a carbon-based material. Specifically, the first conical surface 131 can be provided with a friction material layer, and the second conical surface 141 can be not provided with a friction material layer, or the second conical surface 141 can be provided with a friction material layer, and the first conical surface 131 can be not provided with a friction material layer.

[0048] Furthermore, the angle between the first conical surface 131 and the horizontal axis is a, the angle between the second conical surface 141 and the horizontal axis is b, and the size of the angle a is the same as the size of the angle b. In order to ensure the torque transmission between the clutch inner cone 140 and the clutch outer cone 130 and to ensure that the torque capacity can reach 300 N·m, the angle a satisfies 6°≤a≤9°. In the specific implementation process, the angle a can be 6°, 7°, 8° or 9°.

[0049] Specifically, the movement of the clutch outer cone 130 between the first position and the second position is driven by the first driving mechanism and the second driving mechanism. The first driving mechanism is located on the side of the clutch outer cone 130 away from the clutch inner cone 140. The first driving mechanism abuts against the clutch outer cone 130 and can drive the clutch outer cone 130 to move from the second position to the first position. The second driving mechanism is located on the side of the clutch outer cone 130 facing the clutch inner cone 140. The second driving mechanism abuts against the clutch outer cone 130 and can drive the clutch outer cone 130 to move from the first position to the second position.

[0050] The stroke of the clutch outer cone 130 is greater than or equal to 1.5 mm and less than or equal to 4 mm, that is, the distance between the first position and the second position is greater than or equal to 1.5 mm and less than or equal to 4 mm. Specifically, the stroke of the clutch outer cone 130 can be 1.5 mm, 1.8 mm, 2.2 mm, 2.2 mm, 2.5 mm. In this way, the clutch inner cone 140 and the clutch outer cone 130 can be separated, while avoiding the clutch inner cone 140 and the clutch outer cone 130 from occupying too much space during the movement.

[0051] In this way, the first driving mechanism is provided to drive the clutch outer cone 130 to move to the first position to achieve the coupling of the clutch outer cone 130 and the clutch inner cone 140, thereby achieving the coupling of the first rotating shaft 110 and the second rotating shaft 120, so that the torque can be transmitted between the first rotating shaft 110 and the second rotating shaft 120; the second driving mechanism is provided to drive the clutch outer cone 130 to move to the second position to achieve the separation of the clutch outer cone 130 and the clutch inner cone 140, thereby achieving the separation between the first rotating shaft 110 and the second rotating shaft 120, and the clutch inner cone 140 and the clutch outer cone 130 replace the friction plate, steel plate, wave spring and other structures in the traditional clutch, thereby reducing the number of parts of the clutch and reducing the cost.

[0052] In some embodiments of this application, please continue to refer to Figure 1The first driving mechanism may include an actuator piston 151, a pressure plate 152 and a clutch bearing 153. The actuator piston 151 is arranged in a piston groove 171 and slides with the side wall of the piston groove 171. The piston groove 171 is arranged in a housing 170 and is connected to the oil circuit, wherein the housing 170 is a vehicle transmission housing; the pressure plate 152 includes a first end 1521 and a second end 1522 opposite to each other, and the first end 1521 abuts against the clutch outer cone 130; the clutch bearing 153 is clamped between the second end 1522 and the actuator piston 151.

[0053] The clutch bearing 153 is used to realize the rotation between the pressure plate 152 and the actuator piston 151 .

[0054] In this way, by introducing hydraulic oil into the piston groove 171, the actuator piston 151 is pushed to move, and the actuator piston 151 pushes the pressure plate 152 through the clutch bearing 153. The pressure plate 152 pushes the clutch outer cone 130 toward the clutch inner cone 140, thereby realizing the movement of the clutch outer cone 130 from the second position to the first position, and realizing the coupling of the clutch outer cone 130 and the clutch inner cone 140.

[0055] Among them, see Figure 2 In order to meet the transmission connection between the first rotating shaft 110 and other structures, the first rotating shaft 110 is also provided with a circumferential gear 111 extending toward the circumferential outside, and the circumferential gear 111 is located between the clutch bearing 153 and the clutch outer cone 130. The circumferential gear 111 is provided with an avoidance hole 1111, and the pressure plate 152 is penetrated through the avoidance hole 1111 to achieve the pressure plate 152 abutting between the clutch outer cone 130 and the clutch bearing 153.

[0056] Furthermore, a limiting protrusion 1112 is provided on the peripheral wall of the avoidance hole 1111, and the limiting protrusion 1112 abuts against the pressure plate 152, thereby reducing the contact area between the pressure plate 152 and the avoidance hole 1111, thereby reducing the interference between the pressure plate 152 and the avoidance hole 1111 during movement, and improving the stability of the pressure plate 152 during movement.

[0057] Specifically, the limiting protrusion 1112 is disposed on an inner wall on one side of the circumferential outer side of the avoidance hole 1111 , and the pressure plate 152 abuts against the avoidance protrusion.

[0058] In some embodiments of this application, please continue to refer to Figure 1The actuator piston 151 includes a body portion 1511 and a folded edge portion 1512. The folded edge portion 1512 is located on the circumferential outer side of the body portion 1511. The folded edge portion 1512 is interference fit with the side wall of the piston groove 171, and the body portion 1511 is clearance fit with the side wall of the piston groove 171. Therefore, by providing the folded edge portion 1512, an interference fit between the actuator piston 151 and the piston groove 171 is achieved, so that the hydraulic oil entering the piston groove 171 can push the actuator piston 151 to move. By making the clearance fit between the body portion 1511 and the side wall of the piston groove 171, the interference between the actuator piston 151 and the piston groove 171 during the movement can be reduced.

[0059] Specifically, the folded edge portion 1512 is located on a side of the main body portion 1511 away from the clutch outer cone 130 , so that the movable amount of the actuator piston 151 can be increased when the depth of the piston groove 171 is constant.

[0060] In some embodiments of this application, please continue to refer to Figure 1 The second end 1522 is formed as a bent portion, which is formed by bending a portion of the pressure plate 152 toward the circumferential outer side of the first rotating shaft 110. Thus, the contact area between the pressure plate 152 and the clutch bearing 153 is increased by providing the bent portion, thereby improving the stability of the clutch bearing 153 and the pressure plate 152 during movement.

[0061] In some embodiments of this application, please continue to refer to Figure 1 The first driving mechanism may further include an adjusting gasket 154, which is sandwiched between the actuating piston 151 and the clutch bearing 153. The adjusting gasket 154 is used to adjust the length of the first driving mechanism in the axial direction of the first rotating shaft 110.

[0062] It can be understood that the axial length of the first driving mechanism on the first rotating shaft 110 is m, the axial length of the pressure plate 152 on the first rotating shaft 110 is n, the axial length of the clutch bearing 153 on the first rotating shaft 110 is k, and the axial length of the actuator piston 151 on the first rotating shaft 110 is h. Then, an adjustment gasket 154 with a thickness of mnkh can be selected to ensure a constant length of the first driving mechanism.

[0063] In some embodiments of this application, please continue to refer to Figure 1The second driving mechanism may include an elastic member 161, and the elastic member 161 may include a third end 1611 and a fourth end 1612. The third end 1611 abuts against the first rotating shaft 110, and the fourth end 1612 abuts against the clutch outer cone 130. The elastic member 161 applies a thrust to the clutch outer cone 130 in a direction away from the clutch inner cone 140, thereby realizing the movement of the clutch outer cone 130 from the first position to the second position, realizing the separation between the clutch inner cone 140 and the clutch outer cone 130, and thereby realizing the separation between the first rotating shaft 110 and the second rotating shaft 120.

[0064] An elastic member installation groove 132 is provided on the inner side of the clutch outer cone 130 , which is used to provide an abutment position for the elastic member 161 to ensure the stability of the position of the elastic member 161 .

[0065] In some embodiments of the present application, the second driving mechanism may further include a snap ring 162, which is disposed around the circumferential outer side of the first rotating shaft 110, and the third end 1611 abuts against the snap ring 162. Thus, the snap ring 162 is provided to limit the elastic member 161, thereby achieving abutment with the first rotating shaft 110.

[0066] Specifically, in order to ensure the stability of the position of the snap ring 162 in the axial direction, a snap ring installation groove is provided in the circumferential direction of the first rotating shaft 110, and the snap ring 162 is clamped in the snap ring installation groove.

[0067] Furthermore, the second driving mechanism can also include a retaining ring baffle 163, which is sleeved on the circumferential outer side of the first rotating shaft 110 and clamped between the retaining ring 162 and the third end 1611; the retaining ring baffle 163 includes an extension section 1631, and the extension section 1631 is located on the circumferential outer side of the retaining ring 162. By setting the retaining ring baffle 163, the retaining ring 162 is limited in the circumferential direction to prevent the retaining ring 162 from detaching from the first rotating shaft 110.

[0068] Generally, in order to clamp the retaining ring 162 in the installation groove, the retaining ring 162 is formed as a circular ring with a notch. During the rotation of the first rotating shaft 110, the retaining ring 162 is at risk of detaching from the first rotating shaft 110. The retaining ring baffle 163 is formed in a circular ring shape and is sleeved on the first rotating shaft 110. The extension section 1631 of the retaining ring baffle 163 can prevent the retaining ring 162 from detaching.

[0069] Among them, see Figure 3 There is also lubricating oil connected between the clutch inner cone 140 and the clutch outer cone 130. When the clutch inner cone 140 is separated from the clutch outer cone 130, the lubricating oil can lubricate the relative rotation between the clutch outer cone 130 and the clutch inner cone 140.

[0070] Specifically, the clutch assembly 100 is further provided with a lubricating oil passage 190 , and the lubricating oil passage 190 is used to transport lubricating oil between the clutch inner cone 140 and the clutch outer cone 130 .

[0071] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
