Problems solved by technology

, while the clutch transmits torque through the friction force of the pressure plate pressing the friction plate. If the friction coefficient is large, it is easy to cause excessive friction, and if the friction coefficient is small, it is not conducive to the transmission of torque;
[0003] In recent years, in order to improve the friction and wear performance of brake pads, nano-friction materials have received extensive attention. By adding nanoparticles, the micro-interface structure of friction material components has been significantly improved, which can effectively improve its thermal decay and thermal recovery performance. , by controlling the nano-effects of different shapes and multi-components, the comprehensive performance of nano-friction materials can be improved, especially the high-temperature friction and wear properties can be improved while taking into account the strength and toughness. However, the direct introduction of traditional dry mixing Nano-powders cannot maximize the modification effect of nanoparticles on friction materials, but will have some negative effects. Experience shows that direct mixing of nanoparticles will cause the nanoparticles to adhere to other particles during the mixing process. And on the surface of steel fiber, the bonding strength between the resin material and other materials is reduced, resulting in a small friction coefficient of the friction material and a large increase in the wear rate during the friction process
