Clutch in the flywheel between the engine and gearbox shell, clutch assembly with screws fixed to the flywheel after the plane, the clutch output shaft is a gearbox input shaft. The process of moving the car, the driver can be required or release the clutch pedal is depressed, the engine and gearbox for the time being and the gradual separation of the interface in order to cut off or transfer engine power to the transmission input. Diaphragm spring clutch in recent years in the car and light vehicle widely used as a clutch, the torque capacity of its large and relatively stable, easy to operate, good balance, but also mass production, for which research has become more and more important. This paper is a light truck designed diaphragm spring clutch. According to traffic conditions and vehicle parameters, in accordance with the clutch system design steps and requirements, mainly for the following work: Select the main design parameters are: the determination of friction plate diameter, back-up coefficient of the clutch unit to determine the pressure. And carried out mainly for assembly design: separation equipment design, and design driven plates (the driven plate hub de
