How The Car Clutch Works
- Apr 10, 2018 -

The active part and the driven part of the clutch use the frictional effect between the contact surfaces, either as a transmission medium (hydraulic coupling) or as a magnetic transmission (electromagnetic clutch) to transmit torque between the two. Temporarily separate, it can be gradually joined, allowing the two parts to rotate with each other during the transmission process.

What is widely used today in automobiles is a spring-friction friction clutch (abbreviated as a friction clutch).

The torque generated by the engine is transmitted to the driven plate through friction between the flywheel and the pressure plate and the driven plate contact surface. When the driver depresses the clutch pedal, the large end of the diaphragm spring drives the pressure plate to move backwards through the transmission of the mechanism, and the driven part is separated from the active part at this time.
