Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle clutches, and particularly to an anti-slip structure for a motorcycle clutch friction plate. Background Technique

[0002] The motorcycle clutch friction plate is a core component in the clutch system, responsible for transmitting power between the engine output and the transmission system input. Its main function is to achieve the smooth engagement and separation of engine power through the generation of friction, ensuring the smooth operation of the motorcycle during starting, accelerating, and shifting gears.

[0003] However, in actual use, the motorcycle clutch friction plate often slips due to insufficient friction. This slipping not only reduces the power transmission efficiency but also may cause problems such as poor vehicle acceleration and unstable handling. In severe cases, it may even affect driving safety. Especially under high-temperature and high-load driving conditions, due to structural limitations, traditional friction plates are difficult to effectively address the above challenges, often resulting in increased wear and shortened service life. In view of this, we propose an anti-slip structure for a motorcycle clutch friction plate. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-slip structure for a motorcycle clutch friction plate to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-slip structure for a motorcycle clutch friction plate includes a driving friction plate and a driven friction plate adapted to the driving friction plate. The driving friction plate includes a first annular friction disc, and the outer wall of the first annular friction disc is provided with a plurality of externally protruding portions arranged in a circular array, enabling the driving friction plate to be connected to the driving disc of the motorcycle clutch. Both the left and right sides of the first annular friction disc are provided with a plurality of first sector-shaped friction blocks arranged in a circular array to provide friction and achieve the engagement and separation of power. A plurality of anti-slip grooves are formed on the outer sides of the first sector-shaped friction blocks, which cooperate with triangular blocks to prevent the friction plate from slipping.

[0007] The driven friction plate includes a second annular friction disc, and the inner wall of the second annular friction disc is provided with a plurality of internally protruding portions arranged in a circular array, enabling the driven friction plate to be connected to the driven disc of the motorcycle clutch. Both the left and right sides of the second annular friction disc are provided with a plurality of second sector-shaped friction blocks arranged in a circular array, which cooperate with the first sector-shaped friction blocks to achieve power transmission. The outer sides of the second sector-shaped friction blocks are provided with triangular blocks adapted to the plurality of anti-slip grooves. When multiple motorcycle clutch friction plates are engaged, the triangular blocks can be inserted into the anti-slip grooves, effectively preventing the friction plates from slipping.

[0008] Preferably, a plurality of first U-shaped ventilation grooves arranged in a circular array are formed on both the left and right sides of the first annular friction disc. The plurality of first U-shaped ventilation grooves and the plurality of first sector-shaped friction blocks are arranged in an alternating manner, enabling air flow to pass through the first U-shaped ventilation grooves into the clutch interior, improving the heat dissipation performance, and preventing slippage caused by excessive temperature.

[0009] Preferably, a plurality of ventilation holes a arranged in a circular array are formed on both the left and right sides of the first annular friction disc and near the outer edge. The ventilation holes a communicate with two adjacent first U-shaped ventilation grooves on the left and right, further promoting air circulation and enhancing the heat dissipation effect.

[0010] Preferably, a plurality of circular fixing blocks arranged in a circular array are provided on both the left and right sides of the first annular friction disc and near the inner edge. The plurality of circular fixing blocks are respectively located in the plurality of first U-shaped ventilation grooves. The height of the circular fixing blocks is the same as the thickness of the first sector-shaped friction blocks. The circular fixing blocks cooperate with the separation auxiliary members to completely separate the first sector-shaped friction blocks and the second sector-shaped friction blocks, ensuring the effective separation of the clutch friction plates.

[0011] Preferably, a plurality of second U-shaped ventilation grooves arranged in a circular array are formed on both the left and right sides of the second annular friction disc. The plurality of second U-shaped ventilation grooves and the plurality of second sector-shaped friction blocks are arranged in an alternating manner, enabling air flow to pass through the second U-shaped ventilation grooves into the clutch interior, improving the heat dissipation performance, and preventing slippage caused by excessive temperature.

[0012] Preferably, a plurality of ventilation holes b arranged in a circular array are formed on both the left and right sides of the second annular friction disc and near the outer edge. The ventilation holes b communicate with two adjacent second U-shaped ventilation grooves on the left and right, further promoting air circulation and enhancing the heat dissipation effect.

[0013] Preferably, a plurality of mounting holes arranged in a circular array are formed on the side of the second annular friction disc and near the inner edge. The mounting holes communicate with two adjacent second U-shaped ventilation grooves on the left and right. A separation auxiliary member is provided in each mounting hole to assist in the separation operation of the clutch.

[0014] Preferably, the separation auxiliary member includes a hollow round rod fixedly connected in the mounting hole, which houses a circular slider and a spring. Two circular sliders are slidably connected in the hollow round rod. A spring is provided between the two circular sliders. The circular sliders and the spring cooperate to achieve thrust transmission. Circular push rods are provided on the opposite sides of the two circular sliders. One end of the circular push rod away from the circular slider passes through the inner wall of the hollow round rod to the outside, and the engagement and separation are controlled by sliding.

[0015] Preferably, when the triangular clamping block is clamped in the anti-slip card slot, the outer end of the circular push rod abuts against the outer end of the circular fixing block, and the outer end of the circular fixing block fits against the end of the adjacent hollow circular rod. At this time, the spring is compressed, and the circular push rod is subjected to an outward acting force. When the clutch friction plate is in the separation operation, the adjacent two friction plates can be pushed apart.

[0016] Preferably, when the length of the circular push rod protruding from the end of the hollow circular rod is greater than the depth of the anti-slip card slot, the triangular clamping block is completely removed from the anti-slip card slot, ensuring that the circular push rod can push the circular fixing block away by a sufficient distance to prevent the triangular clamping block from contacting the anti-slip card slot.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. For the anti-slip structure of the motorcycle clutch friction plate, through the cooperation of the anti-slip card slot and the triangular clamping block, the slipping phenomenon of the friction plate during power transmission can be effectively prevented. This design ensures the stable transmission of power and improves the acceleration performance and handling stability of the motorcycle.

[0019] 2. For the anti-slip structure of the motorcycle clutch friction plate, the design of the U-shaped ventilation groove and the ventilation hole greatly improves the air circulation effect. This structure effectively reduces the temperature of the friction plate under high-temperature and high-load conditions, prevents slipping and wear caused by overheating, and thus improves the overall heat dissipation performance.

[0020] 3. For the anti-slip structure of the motorcycle clutch friction plate, the design of the separation auxiliary part and the circular fixing block ensures the smoothness of the friction plate during the separation operation. This design can effectively push the friction plate apart, improve the operating performance of the clutch, and reduce the failure rate during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Please refer to Figures 1 - 8 , the present utility model provides a technical solution:

[0033] An anti-slip structure for a motorcycle clutch friction plate, including a driving friction plate 1 and a driven friction plate 2 adapted to the driving friction plate 1. The driving friction plate 1 includes a first annular friction disc 10. The outer wall of the first annular friction disc 10 is provided with a plurality of outer protrusions 11 arranged in an annular array, so that the driving friction plate 1 can be connected to the driving disc of the motorcycle clutch. On both the left and right sides of the first annular friction disc 10, a plurality of first sector-shaped friction blocks 12 are arranged in an annular array to provide frictional force and realize the engagement and separation of power. A plurality of anti-slip grooves 120 are formed on the outer side of the first sector-shaped friction block 12, which cooperate with the triangular blocks 220 to prevent the friction plate from slipping.

[0034] The driven friction plate 2 includes a second annular friction disc 20. The inner wall of the second annular friction disc 20 is provided with a plurality of inner protrusions 21 arranged in an annular array, so that the driven friction plate 2 can be connected to the driven disc of the motorcycle clutch. On both the left and right sides of the second annular friction disc 20, a plurality of second sector-shaped friction blocks 22 are arranged in an annular array to cooperate with the first sector-shaped friction blocks 12 to realize power transmission. The outer side of the second sector-shaped friction block 22 is provided with triangular blocks 220 adapted to a plurality of anti-slip grooves 120. When multiple motorcycle clutch friction plates are engaged, the triangular blocks 220 can be inserted into the anti-slip grooves 120 to effectively prevent the friction plates from slipping.

[0035] In this embodiment, a plurality of first U-shaped ventilation grooves 100 are formed on both the left and right sides of the first annular friction disc 10 and arranged in an annular array. The plurality of first U-shaped ventilation grooves 100 and the plurality of first sector-shaped friction blocks 12 are arranged in a staggered manner, so that air flow can pass through the first U-shaped ventilation grooves 100 to the inside of the clutch, improving the heat dissipation performance and preventing slipping caused by excessive temperature.

[0036] Specifically, a plurality of ventilation holes a101 are formed on both the left and right sides of the first annular friction disc 10 and near the outer edge and arranged in an annular array. The ventilation holes a101 are communicated with two adjacent first U-shaped ventilation grooves 100 on the left and right to further promote air circulation and enhance the heat dissipation effect.

[0037] Furthermore, a plurality of circular fixing blocks 3 are arranged on both the left and right sides of the first annular friction disc 10 and near the inner edge and arranged in an annular array. The plurality of circular fixing blocks 3 are respectively located in the plurality of first U-shaped ventilation grooves 100. The height of the circular fixing blocks 3 is the same as the thickness of the first sector-shaped friction blocks 12. The circular fixing blocks 3 cooperate with the separation auxiliary member 4 to completely separate the first sector-shaped friction blocks 12 and the second sector-shaped friction blocks 22, ensuring the effective separation of the clutch friction plates.

[0038] Further, a plurality of second U-shaped ventilation grooves 200 arranged in a circular array are formed on both the left and right sides of the second annular friction disc 20. The plurality of second U-shaped ventilation grooves 200 and the plurality of second sector-shaped friction blocks 22 are arranged in an alternating manner, enabling air flow to pass through the second U-shaped ventilation grooves 200 into the clutch interior, improving the heat dissipation performance, and preventing slippage caused by excessive temperature.

[0039] Further, a plurality of ventilation holes b201 arranged in a circular array are formed at positions near the outer edge on both the left and right sides of the second annular friction disc 20. The ventilation holes b201 communicate with two adjacent second U-shaped ventilation grooves 200 on the left and right, further promoting air circulation and enhancing the heat dissipation effect.

[0040] Further, a plurality of mounting holes 202 arranged in a circular array are formed at positions near the inner edge on the side surface of the second annular friction disc 20. The mounting holes 202 communicate with two adjacent second U-shaped ventilation grooves 200 on the left and right. A separation auxiliary member 4 is provided in each mounting hole 202 to assist in the separation operation of the clutch.

[0041] Further, the separation auxiliary member 4 includes a hollow round rod 40 fixedly connected in the mounting hole 202, accommodating a circular slider 41 and a spring 43. Two circular sliders 41 are slidably connected in the hollow round rod 40. A spring 43 is provided between the two circular sliders 41. The circular slider 41 cooperates with the spring 43 to achieve thrust transmission. Circular push rods 42 are provided on the opposite side surfaces of the two circular sliders 41. One end of the circular push rod 42 away from the circular slider 41 passes through the inner wall of the hollow round rod 40 to the outside, and the control of engagement and separation is achieved through sliding.

[0042] Further, when the triangular block 220 is clamped in the anti-slip groove 120, the outer end of the circular push rod 42 abuts against the outer end of the circular block 3. The outer end of the circular block 3 fits against the end of the adjacent hollow round rod 40. At this time, the spring 43 is compressed, and the circular push rod 42 receives an outward acting force. When the clutch friction plate is separated, it can push the two adjacent friction plates apart.

[0043] Further, when the length of the circular push rod 42 protruding from the end of the hollow round rod 40 is greater than the depth of the anti-slip groove 120, the triangular block 220 is completely removed from the anti-slip groove 120, ensuring that the circular push rod 42 can push the circular block 3 away by a sufficient distance, avoiding contact between the triangular block 220 and the anti-slip groove 120.

[0044] When the anti-slip structure of the motorcycle clutch friction plate in this embodiment is in use, the driving friction plate 1 and the driven friction plate 2 are respectively installed on the driving disc and the driven disc of the motorcycle, ensuring that the external protrusions 11 and the internal protrusions 21 are tightly fitted with the card slots of the corresponding discs to ensure stable connection. When the motorcycle is running, the power output by the engine is transmitted to the driven friction plate 2 through the driving friction plate 1. The first sector friction blocks 12 and the second sector friction blocks 22 on the friction plate provide sufficient friction force to ensure the effective transmission of power. The cooperation of the anti-slip card slots 120 and the triangular blocks 220 prevents the friction plate from slipping under high load or high temperature conditions, thereby stabilizing the acceleration and handling performance of the motorcycle. The designed first U-shaped ventilation groove 100, second U-shaped ventilation groove 200, ventilation holes a101 and ventilation holes b201 promote the flow of air around the friction plate, improve the heat dissipation efficiency, and prevent performance degradation or wear caused by high temperature. The separation auxiliary part 4 is adopted, and the smooth separation of the friction plate is ensured through the circular push rod 42 and the circular fixing block 3. When the clutch needs to be separated, the circular push rod 42 pushes the friction plates apart to ensure flexible operation and reduce the failure rate. Regularly check the wear state of the friction plate and the matching condition of the blocks to ensure stable connection and anti-slip effect during long-term use. If abnormal wear or poor block matching is found, it should be replaced or adjusted in time to maintain good use performance. This structural design not only improves the stability of power transmission, but also enhances the heat dissipation performance and the service life of the friction plate, ensuring the safe and efficient operation of the motorcycle under different driving conditions.
