Working principle and purpose of clutch disk (plate). The clutch plate is the driving member of the clutch and is gripped between the flywheel and the pressure plate. It is mounted on the clutch shaft through the splines. When it is gripped, rotates the clutch shaft and the power is transmitted from the engine to the transmission through the clutch. A pressure plate consists of two sets of facing or friction material mounted on steel cushion springs. The facing and cushion springs are riveted to a spring base disc and spring retainer plate which are slotted for the insertion of the torsion spring. These springs contact the hub flanges that fit between the spring retainer plate and the disc and serve to transmit the twisting force applied to the facings to the splined hub. The spring action serves to reduce torsional vibrations and shocks between the engine and the transmission during clutch operation. The facing and the plates rotate with respect to the hub to the limit of the compression of the springs or to the limit of the spring stops. When the clutch is engaged, the pressure on the facing compresses the cushion springs sufficiently to cause the unit to decrease in thickness by 1 to 1.5 mm. This construction helps to make engagement smooth and chatterless.
