Problems solved by technology
[0002] The power transmission mechanism of a vehicle generally includes a gearbox, a drive shaft, and a drive axle. The gearbox is used to transmit power and change the speed ratio of the transmission to obtain a larger driving speed range; the current gearboxes use split flywheels. The combination of disk, dry friction plate and pressure plate, because the vehicle often needs to be semi-combined to start, the dry friction plate is seriously worn and needs frequent maintenance and replacement
