The clutch is a transmission mechanism which has a driving part and a driven part, wherein the driving part and the driven part can be separated temporarily or combined slowly, and relative rotation can be generated in the transmission process, so that torque can be transmitted between a driving part and a driven part of the clutch by means of contact friction, or the torque can be transmitted by means of pressing force required by friction, or liquid serving as a transmission medium, or magnetic transmission and the like. Friction clutches that are pressed by springs are widely used in motor vehicles.
Friction between the friction plates and the flywheel and pressure plate occurs during the clutch from disengagement to engagement, and a large amount of heat is generated during the slow increase in speed of the driven portion, particularly during the initial engagement. The heat needs to be dissipated in time to avoid damage to the friction plate due to excessive temperature. In the prior art, heat dissipation is mainly performed by arranging heat dissipation holes, but the heat dissipation mode is low in efficiency and low in speed, and the current requirements are difficult to meet.
The friction plate technology is a clutch component with simple structure, wide applicability and convenient installation and maintenance, an important factor restricting the popularization and application of the clutch at present is the lack of a brake friction material with excellent cost performance, the clutch has high requirements on the friction material, needs to have stable friction and wear performance, better high temperature resistance and low noise, can meet the requirement of continuous opening operation for more than ten thousand times, keeps stable service performance, simultaneously, the material also needs to meet the requirements of EU ROHS environmental protection and related restricted material instructions, and does not contain substances affecting human health such as asbestos, lead, cadmium, mercury, hexavalent chromium and the like.
