The document defines and describes the main components and operation of a car clutch. A clutch connects and disconnects the driving and driven parts of a car to allow for changing gears. The key parts are the flywheel, clutch plate, pressure plate, and release fork. The flywheel stores kinetic energy from the engine. The clutch plate transmits power between the flywheel and gearbox. The pressure plate uses a diaphragm spring to squeeze the clutch plate and connect it to the flywheel. The release fork connects the clutch to the pedal to engage and disengage the clutch.
