Though the installation and structure is different, but their functions are the same. Insight into the working principle of the clutch for us to understand life better machinery is of great benefit. Clutch is an important part in automotive transmission system, is the main function is to cut off the and realize the engine to the transmission of power transmission, ensure smooth start of the car, for ensuring the smooth and transmission when shifting transmission system on the maximum torque, to prevent the transmission system overload. Diaphragm spring clutch is widely used in cars and light motor vehicles in recent years of a clutch, its great capacity of torque and relatively stable, convenient operation, good balance, can also be a large number of production, has become more and more important for its research. Diaphragm spring clutch is relative to the spiral spring clutch has a series of advantages: the nonlinear characteristics of diaphragm spring to make the whole process of wear and tear in friction, maintain invariable pressure plate by basic compaction force, to ensure the clutch performance is more stable; Separation of th
