D3.5 Driven plate assembly What is widely used is a friction clutch pressed by a spring (friction clutch for short). The torque generated by the engine is transmitted to the driven plate through the friction between the flywheel and the contact surface between the pressure plate and the driven plate. When the driver depresses the clutch pedal, the large end of the diaphragm spring drives the pressure plate to move backward through the transmission of the mechanical parts. At this time, the driven part is separated from the active part.
