The Working Principle Of The Friction Clutch

- Sep 21, 2017 -

The engine flywheel is the master of the clutch, the driven plate with the friction plate and the driven hub are connected by the sliding spline to the driven shaft (ie, the drive shaft). The compression spring presses the driven plate against the flywheel end face. The engine torque is transmitted to the driven disc by the friction between the flywheel and the contact surface of the driven plate, which is then passed to the drive wheels via a series of components in the driven shaft and the drive train. The greater the compressive force of the compression spring, the greater the torque that the clutch can deliver.

As the car in the process of running, often need to maintain power transmission, and interrupt the drive is only a temporary need, so the active part of the clutch and the clutch part is often in the state of engagement. The friction pair is a spring fastening device in order to meet this requirement. When the clutch is desired to be disengaged, the pedal in the ring groove of the driven hub is pushed as long as the pedal in the clutch operating mechanism is depressed to push the driven plate against the pressure of the compression spring to the release direction, Separation, friction disappeared, thus interrupting the transmission of power.
