The driven disc is mainly composed of the driven disc body, the friction disc and the driven disc hub. It can be said that the parts are composed of driven steel, friction plate, torsion damper, driven disc hub and other four parts. driven steel: the driven steel is riveted with a torsion damper disc, between which there is a disc driven hub. Friction plate: Torque transmission. Torsion damper: Effectively prevents transmission torsional vibrations. Driven hub, etc.: Torque transmission. The clutch disc is another component of the clutch, through the transformation of friction, transfers the engine torque to the transmission, reduces vibration and shock of the transmission system, performs the tasks of "removing" and "connecting".
