Its function as: (1) the car a smooth start, (2) to interrupt the transmission of power to meet the shift, (3) to prevent transmission of the overload. In recent years theca spring clutch is a kind of clutch that widely Adopted in vehicle and light vehicle . It has great capacity of torque And more stabley ,manipulate easy and convenient ,well equilibrium ,And also can produce batch .so the research of the clutch is more and more important . This design manual elaborated on the construction form,parametre choose and process of calculate of the light vehicle. This design is mainly for the clutch of the BMW 325im.
