Description

Technical Field

[0001] This utility model relates to the field of clutch disc technology, specifically a high-friction, anti-slip clutch disc. Background Technology

[0002] The clutch disc is a key component of a vehicle's clutch system, playing a crucial role in transmitting engine power to the transmission. When the clutch is engaged, the clutch disc's primary function is to achieve smooth power transmission through friction. During this process, the friction material contacts the pressure plate surface, and the engine's power is smoothly and effectively transmitted to the transmission system through the action of friction.

[0003] However, in actual use, clutch plates often slip due to insufficient friction. This slippage usually occurs when the vehicle is starting, accelerating, or operating under high load. Slippage caused by insufficient friction not only accelerates the wear of the clutch plates and shortens the clutch's lifespan, but also significantly reduces power transmission efficiency, resulting in wasted engine power.

[0004] Slippage can negatively impact the driving experience in several ways. First, reduced power transmission efficiency leads to sluggish acceleration, resulting in decreased acceleration performance and fuel efficiency. Second, slippage can cause vehicle instability during driving, especially when shifting gears or requiring precise speed control; this instability can threaten driving safety. Furthermore, frequent slippage can accelerate wear on other transmission components, leading to higher maintenance and replacement costs.

[0005] Therefore, in order to solve the slippage problem caused by insufficient friction in traditional clutch plates in practical applications, it is particularly important to improve the friction performance and durability of clutch plates. In view of this, we propose a high-friction anti-slip clutch plate. Utility Model Content

[0006] The purpose of this invention is to provide a high-friction, anti-slip clutch disc to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-friction, anti-slip clutch disc includes an active clutch disc and a driven clutch disc adapted to the active clutch disc. The active clutch disc has multiple first friction discs arranged in a circular array on both its left and right sides. Each first friction disc has multiple hemispherical protrusions on the side away from the active clutch disc. The driven clutch disc has multiple second friction discs arranged in a circular array on both its left and right sides. Each second friction disc has multiple hemispherical anti-slip grooves on the side away from the driven clutch disc. The number of first and second friction discs is the same. When the active and driven clutch discs are engaged to transmit power, adjacent first and second friction discs abut against each other. The hemispherical protrusions are located within the hemispherical anti-slip grooves. The combination of multiple hemispherical protrusions and hemispherical anti-slip grooves increases the friction surface and effectively prevents slippage after the first and second friction discs abut against each other, ensuring the effectiveness of power transmission.

[0009] Preferably, the outer wall of the driving clutch plate is provided with a plurality of first connecting protrusions arranged in a ring array for connecting with the driving disc of the clutch, and the inner wall of the driven clutch plate is provided with a plurality of second connecting protrusions arranged in a ring array for connecting with the driven disc of the clutch.

[0010] Preferably, the active clutch plate is provided with multiple first arc-shaped heat dissipation fins on both the left and right sides. The first arc-shaped heat dissipation fins are integrally formed with the active clutch plate. When the active clutch plate rotates, airflow can be generated, thereby improving the heat dissipation effect of the active clutch plate.

[0011] Preferably, the driven clutch plate is provided with multiple second arc-shaped heat dissipation fins on both the left and right sides. The second arc-shaped heat dissipation fins are integrally formed with the driven clutch plate. When the driven clutch plate rotates, airflow can be generated, thereby improving the heat dissipation effect of the driven clutch plate.

[0012] Preferably, the first friction plate has circular holes on the side away from the active clutch plate and near the four corners. A spring is installed in each circular hole, and one end of the spring is fixedly connected to the side of the active clutch plate to fix its position. A separation push block is fixedly connected to the end of the spring away from the active clutch plate. When the spring is not compressed, the hemispherical protrusion is completely separated from the hemispherical anti-slip groove. When the active clutch plate and the driven clutch plate are pressed together to transmit power, the spring is compressed, and the separation push block abuts against the second friction plate. This allows for rapid separation when the active clutch plate and the driven clutch plate need to be separated.

[0013] Preferably, the first friction plate is provided with a plurality of first arc-shaped ventilation grooves on the side away from the active clutch plate to improve the heat dissipation effect of the first friction plate.

[0014] Preferably, the second friction plate has multiple second arc-shaped ventilation grooves on the side away from the driven clutch plate to improve the heat dissipation effect of the second friction plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This high-friction anti-slip clutch disc, by setting multiple hemispherical protrusions and corresponding hemispherical anti-slip grooves, can increase the friction surface and enhance the friction force. This design effectively prevents the slippage problem of traditional clutch discs when the vehicle starts, accelerates or operates under high load, thereby greatly improving the efficiency of power transmission.

[0017] 2. This high-friction, anti-slip clutch disc, by incorporating arc-shaped heat dissipation fins and arc-shaped ventilation grooves, enhances the heat dissipation effect of the clutch disc during operation. This effectively reduces the impact of high-temperature conditions on the performance and durability of the clutch disc, further improving its stability and service life. Attached Figure Description

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A high-friction, anti-slip clutch disc includes a driving clutch disc 1 and a driven clutch disc 2 adapted to the driving clutch disc 1. The driving clutch disc 1 has multiple first friction discs 3 arranged in a circular array on both its left and right sides. The side of each first friction disc 3 away from the driving clutch disc 1 has multiple hemispherical protrusions 30. The driven clutch disc 2 has multiple second friction discs 4 arranged in a circular array on both its left and right sides. The side of each second friction disc 4 away from the driven clutch disc 2 has multiple hemispherical anti-slip grooves 40. The number of first friction discs 3 is the same as the number of second friction discs 4. When the driving clutch disc 1 and the driven clutch disc 2 are engaged to transmit power, adjacent first friction discs 3 and second friction discs 4 abut against each other. The hemispherical protrusions 30 are located within the hemispherical anti-slip grooves 40. The cooperation of the multiple hemispherical protrusions 30 and the multiple hemispherical anti-slip grooves 40 increases the friction surface and effectively prevents slippage after the first friction discs 3 and second friction discs 4 abut against each other, ensuring the effectiveness of power transmission.

[0027] In this embodiment, the outer wall of the active clutch plate 1 is provided with a plurality of first connecting protrusions 10 arranged in a ring array for connecting with the active disc of the clutch, and the inner wall of the driven clutch plate 2 is provided with a plurality of second connecting protrusions 20 arranged in a ring array for connecting with the driven disc of the clutch.

[0028] Specifically, multiple first arc-shaped heat dissipation fins 11 are provided on both the left and right sides of the active clutch plate 1. The first arc-shaped heat dissipation fins 11 are integrally formed with the active clutch plate 1. When the active clutch plate 1 rotates, airflow can be generated, thereby improving the heat dissipation effect of the active clutch plate 1.

[0029] Furthermore, multiple second arc-shaped heat dissipation fins 21 are provided on both the left and right sides of the driven clutch plate 2. The second arc-shaped heat dissipation fins 21 are integrally formed with the driven clutch plate 2. When the driven clutch plate 2 rotates, airflow can be generated, thereby improving the heat dissipation effect of the driven clutch plate 2.

[0030] Furthermore, the first friction plate 3 has circular holes 32 on the side away from the active clutch plate 1 and near the four corners. A spring 33 is installed in the circular hole 32. One end of the spring 33 is fixedly connected to the side of the active clutch plate 1, so that one end of the spring 33 is fixed in position. The end of the spring 33 away from the active clutch plate 1 is fixedly connected to the separation push block 34. When the spring 33 is not compressed, the hemispherical protrusion 30 is completely separated from the hemispherical anti-slip groove 40. When the active clutch plate 1 and the driven clutch plate 2 are pressed together to transmit power, the spring 33 is compressed and the separation push block 34 abuts against the second friction plate 4. In this way, the active clutch plate 1 and the driven clutch plate 2 can be quickly separated when they need to be separated.

[0031] Furthermore, multiple first arc-shaped ventilation slots 31 are provided on the side of the first friction plate 3 away from the active clutch plate 1 to improve the heat dissipation effect of the first friction plate 3.

[0032] Furthermore, the second friction plate 4 has multiple second arc-shaped ventilation slots 41 on the side away from the driven clutch plate 2 to improve the heat dissipation effect of the second friction plate 4.

[0033] In this embodiment, the high-friction anti-slip clutch plate is used such that the driving clutch plate 1 is connected to the driving disc via the first connecting protrusion 10, and the driven clutch plate 2 is connected to the driven disc via the second connecting protrusion 20. During clutch operation, the driving clutch plate 1 and the driven clutch plate 2 are pressed into contact. The hemispherical protrusion 30 on the first friction plate 3 and the hemispherical anti-slip groove 40 on the second friction plate 4 are tightly engaged, increasing the friction area to enhance friction, preventing slippage and ensuring smooth and effective power transmission between the engine and the transmission. When the vehicle starts, accelerates, or is under high load, the engagement between the hemispherical protrusion 30 and the hemispherical anti-slip groove 40 prevents clutch plate slippage, improving the vehicle's acceleration performance and operational stability. For heat dissipation management, the driving clutch plate 1 and the driven clutch plate 2 are engaged. The clutch plates 2 are respectively provided with a first arc-shaped heat dissipation fin 11 and a second arc-shaped heat dissipation fin 21. The heat dissipation effect is improved by rotating airflow. The first friction plate 3 and the second friction plate 4 are respectively provided with a first arc-shaped ventilation groove 31 and a second arc-shaped ventilation groove 41 to enhance air circulation and heat dissipation capacity, thereby reducing the impact of high temperature on clutch performance and durability. In order to achieve rapid separation, the spring 33 inside the clutch plate is placed in the circular hole 32 of the first friction plate 3 and fixed on the active clutch plate 1. When the spring 33 is compressed, the separation push block 34 abuts against the second friction plate 4, pushing the hemispherical protrusion 30 out of the hemispherical anti-slip groove 40, thereby conveniently disconnecting the power transmission. This innovative design ensures that the service life and performance stability and safety of the clutch plate are improved under various operating conditions.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
