The diaphragm spring clutch of Pacific Auto Network is a clutch made of diaphragm spring instead of general spiral spring and release lever mechanism. Because it is arranged in the center, it can also be regarded as a central spring clutch. The clutch cover and the engine flywheel are fastened together by bolts. When the diaphragm spring is preloaded and the clutch is in the engaged position, friction occurs between the pressure plate and the friction plate of the driven plate due to the pressure from the big end of the diaphragm spring.

Clutch relies on friction principle to transmit engine power. Disadvantages of diaphragm spring clutch Disadvantages of diaphragm spring clutch The manufacturing process of diaphragm spring is complex, the manufacturing cost is high, and the requirements for materials and accuracy are high. Its nonlinear elastic characteristics are difficult to control in production, cracks are easy to occur at the opening and the ends are easy to wear.

In the general compression diaphragm spring clutch, when the support ring is worn, the gap between the diaphragm spring and the support ring leads to the increase of the free stroke of the clutch pedal, while in the pull diaphragm spring clutch, the above shortcomings can be eliminated.
