[0016] 2. The utility model discloses a clutch plate with a sealing structure. The clutch plate is composed of three parts: friction material, adhesive and filler. In order to enhance the overall protective performance of the clutch plate, the clutch plate of the utility model is mainly composed of a clutch steel plate assembly, a filling layer and a composite friction layer. The composite friction layer is also called a friction pair material, which is one of the most important materials of the clutch plate and is composed of materials containing high temperature stability, fatigue strength, friction coefficient and friction peak. When the vehicle is running, the contact surface between the gear and the clutch plate will be worn.

At the same time, it can also adjust the elasticity and stability of the clutch plate and increase the service life of the clutch plate. Commonly used fillers include asbestos, glass fiber, carbon black, etc. These fillers can make the clutch steel plate assembly more solid and prevent the friction material from breaking or delaminating. At the same time, the fillers can also increase the vibration strength and overheating resistance of the clutch steel plate assembly. This high-temperature melting of the composite friction layer on the outer peripheral surface of the clutch steel plate assembly can effectively improve the friction performance of the clutch plate. The finished product has the advantages of high density, good high-temperature rotation burst strength, smoothness and good wear resistance during use, which can extend the service life of the clutch plate.
