Description

Technical Field

[0001] This utility model relates to the technical field of pressure plates for clutches, specifically a pressure plate for clutches. Background Technology

[0002] The clutch pressure plate is one of the key components in the clutch system. It is usually a metal disc installed inside the clutch assembly. The main function of the clutch pressure plate is to apply pressure to make the clutch disc contact or separate from the flywheel. When the driver depresses the clutch pedal, the clutch pressure plate will gradually transmit the power from the engine to the gearbox through the action of the pressure plate and the clutch spring, and finally drive the wheels.

[0003] Patent document CN222687158U discloses a pressure plate for a truck clutch, including a pressure plate body. Multiple limiting support arc plates are evenly fixedly connected to the top circumference of the pressure plate body. Multiple mounting plates are evenly fixedly connected to the outer circumference of the pressure plate body. Torque support blocks are fixedly connected to the left side of each mounting plate. Multiple positioning slots are formed on the inner side of the limiting support arc plates around the top circumference of the pressure plate body. Positioning fixing posts are inserted into the interior of each positioning slot. Support and limiting components are installed on the exterior of each positioning fixing post. A cooling and heat dissipation component is installed inside the pressure plate body. This design further improves the stability of the device, enhances the pressure plate's resistance to pressure deformation, and thus extends its service life. It also rapidly draws and dissipates heat generated by friction on the inner side of the pressure plate during operation, thereby further improving the device's heat dissipation capabilities.

[0004] While the aforementioned application documents further improve the stability of the device, enhance the pressure plate's resistance to deformation, and thus extend its service life, and quickly draw the heat generated by friction on the inner side of the pressure plate to the outer side during operation, thereby further improving the device's heat dissipation capabilities, the dust and shavings generated by the wear of the clutch friction plates during use will move outwards under the action of centrifugal force. With nowhere to go, these shavings may fly around inside the clutch housing and even come into contact with other components (such as the release bearing), affecting operation, impacting the smooth engagement of the clutch, causing vibration, slippage, and accelerated wear.

[0005] Therefore, a pressure plate for a clutch is proposed to solve the problems mentioned above. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a pressure plate for a clutch, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a pressure plate body, wherein a chip collection assembly is mounted on the front side of the pressure plate body;

[0008] The chip collection assembly includes a chip collection groove, a knurled line, and an arc-shaped opening. The chip collection groove is located on the front side of the pressure plate body, the knurled line is located on the front side of the inner wall of the chip collection groove, and the arc-shaped opening is located on both sides of the chip collection groove. A heat dissipation assembly is installed on the front side of the pressure plate body.

[0009] Preferably, the heat dissipation component includes an outer heat dissipation hole, an inner heat dissipation hole, and an arc-shaped fixing block. The outer heat dissipation hole is opened on the front side of the pressure plate body, the inner heat dissipation hole is opened on the front side of the pressure plate body, and the arc-shaped fixing block is fixedly connected to the outer wall of the arc-shaped surface of the inner heat dissipation hole.

[0010] Preferably, there are six chip collection grooves, distributed at the edge of the pressure plate body.

[0011] Preferably, there are six inner heat dissipation holes distributed at the axis of the pressure plate body, and multiple outer heat dissipation holes distributed between the chip collection groove and the inner heat dissipation holes.

[0012] Preferably, the inner heat dissipation holes protrude from the pressure plate body, and the arc-shaped fixing block is integrally formed and fixedly connected to the outer wall of the arc-shaped surface of the six inner heat dissipation holes.

[0013] Preferably, the back of the pressure plate body is provided with multiple toothed grooves, the outer heat dissipation hole is fixedly inserted through the pressure plate body, and the inner heat dissipation hole is fixedly inserted through the pressure plate body.

[0014] Preferably, the pressure plate body has a mounting hole on its front side, and a fixing bolt is inserted inside the mounting hole.

[0015] Compared with the prior art, the present invention provides a pressure plate for a clutch, which has the following advantages:

[0016] 1. During the clutch operation, the wear debris generated by friction between the friction plate and the pressure plate body is thrown to the edge under the action of centrifugal force. The existence of the chip collection groove provides a special collection area for the wear debris. Since the wear debris is collected in a concentrated manner, it can prevent the wear debris from falling randomly on the surface of the pressure plate body and reduce the interference of wear debris to other parts.

[0017] Second, the inner heat dissipation holes and the arc-shaped fixing block together form a high-efficiency centrifugal fan. When the pressure plate body heats up due to friction, the inner heat dissipation holes protrude from the pressure plate body. When rotating, the wall of this protruding structure will actively collide with the air molecules in front of it, transferring the rotational kinetic energy of the pressure plate body to the air, forcing the air to move.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] See Figures 1-4 This embodiment provides a pressure plate for a clutch, including a pressure plate body 1, and a chip collection assembly is mounted on the front of the pressure plate body 1;

[0026] The chip collection assembly includes a chip collection groove 2, a knurled line 3, and an arc-shaped opening 4. The chip collection groove 2 is located on the front of the pressure plate body 1, the knurled line 3 is located on the front of the inner wall of the chip collection groove 2, and the arc-shaped opening 4 is located on both sides of the chip collection groove 2. A heat dissipation assembly is installed on the front of the pressure plate body 1.

[0027] When the clutch is in a high-load working state of engagement and disengagement, the wear debris generated by friction between the friction plate and the pressure plate body 1 is thrown to the edge under the action of centrifugal force. Regardless of where the wear debris is generated, it will be thrown to the outer edge of the pressure plate under the action of centrifugal force. The chip collection groove 2 set on the outer edge of the pressure plate body 1 is located on the inevitable path of the wear debris. When the wear debris moves to this point, it will naturally fall into this groove, preventing the wear debris from continuing to fly outward. The chip collection groove 2 effectively collects the waste debris generated by wear. In this process, the knurled lines 3 on the inner wall of the groove increase the friction force to firmly lock the wear debris, preventing it from escaping and causing secondary wear. The arc-shaped openings 4 on both sides of the chip collection groove 2 can effectively eliminate stress concentration and improve the fatigue resistance of the parts under long-term alternating stress.

[0028] See Figures 2-3The heat dissipation assembly includes an outer heat dissipation hole 5, an inner heat dissipation hole 6, and an arc-shaped fixing block 7. The outer heat dissipation hole 5 is located on the front side of the pressure plate body 1, and the inner heat dissipation hole 6 is located on the front side of the pressure plate body 1. The arc-shaped fixing block 7 is fixedly connected to the outer wall of the arc-shaped surface of the inner heat dissipation hole 6. There are six chip collection grooves 2, which are distributed at the edge of the pressure plate body 1. There are six inner heat dissipation holes 6, which are distributed at the axis of the pressure plate body 1. Multiple outer heat dissipation holes 5 are distributed between the chip collection grooves 2 and the inner heat dissipation holes 6. The inner heat dissipation holes 6 protrude from the pressure plate body 1. The arc-shaped fixing block 7 is integrally formed and is fixedly connected to the outer wall of the arc-shaped surface of the six inner heat dissipation holes 6. Multiple toothed grooves 10 are opened on the back side of the pressure plate body 1. The outer heat dissipation holes 5 are fixedly connected through the pressure plate body 1, and the inner heat dissipation holes 6 are fixedly connected through the pressure plate body 1.

[0029] When the pressure plate body 1 heats up due to friction, the six inner heat dissipation holes 6 protruding from the pressure plate body 1 and the arc-shaped fixing block 7 integrally formed on its arc-shaped surface together form a high-efficiency centrifugal fan. When the heat dissipation holes 6 protrude from the pressure plate body 1, during rotation, the wall of this protruding structure will actively collide with the air molecules in front of it and transfer its own rotational kinetic energy to the air, forcing the air to move. The integrally formed smooth arc-shaped surface greatly reduces the frictional resistance and eddy current generation of airflow. The arc-shaped design ensures that the airflow is attached and smooth. When the pressure plate rotates at high speed, it actively pumps out the hot air accumulated in the core area, which works in conjunction with the multiple outer heat dissipation holes 5 distributed on the pressure plate body 1 to form a through heat dissipation airflow path. Thus, the heat generated by friction is quickly and efficiently discharged during operation, which together ensures the reliability, smoothness and long service life of the clutch power transmission under harsh working conditions.

[0030] The pressure plate body 1 has a mounting hole 8 on the front, and a fixing bolt 9 is inserted inside the mounting hole 8.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
