Friction Clutches

A Friction Clutch is a device for interfacing a prime mover (such as a an engine or motor) with a transmission. The basic principle of operation is that a rotating flywheel, attached to the output shaft of the motor, interacts with the friction disc of the clutch, which is attached to input shaft of the transmission. When the clutch is engaged, the friction disc is pressed against the flywheel, and rotation is transferred between the motor and transmission shafts. When the clutch is released, the contact between the friction disc and flywheel is broken, and rotation can not be transferred to the transmission. Friction Clutches are used in automobiles, as well as other applications.
