A clutch disc such as the GMC clutch disc is a component of an automobile transmission that engages or disengages the transmission of engine output without stopping the engine. The clutch disc transfers torque, speed and power from the flywheel. It is basically comprised of a spring mechanism and a clutch plate covered with friction material Asbestos and rough metal alloy layers comprise the friction material. Heat that may be generated is absorbed by the friction material. Idle mode is made possible by the clutch. The other systems of the vehicle can still function even though the wheels are not moving.

A clutch allows the vehicle to stop without necessarily stopping the wheels from rotating. This is very critical in certain situations such as making emergency parking. On the other hand, if you simply desire to put the vehicle in idle mode and still enjoy the comfort features of your vehicle, you can disengage the clutch. The air conditioning or heating system can still function when the clutch is disengaged. The clutch of an automobile can gradually engage the flywheel of the engine without disrupting the engine power. You can conveniently switch from idle mode to drive mode by re-engaging the clutch.

An automobile clutch directly transfers the engine output in terms of power, speed and torque to the transmission shaft. However, torque, speed and power are not constant. Engine output is intolerably erratic. This is primarily because of the nature of combustion, which is somewhat fluctuating. Fuel combustion is rapid and relatively unstable. The fluctuations in engine output are caused by the combustion cycle, which undergoes rapid succession of energy peaks and lows. The thermal energy generated by combustion builds pressure impulses that drive the pistons to move. For every complete cycle, the pistons do not have exactly the same amount of energy.

Nonetheless, engine fluctuations are made negligible by the transmission system that includes the clutch disc, the transmission shaft, the differential gears and drive shafts. Engine output in the wheels is relatively more stable. Engine output transmission in an automobile involves the translation and modification of motion that begins with the crankshaft. First, the reciprocating linear motions of the pistons are converted into rotational motion by the crankshaft. Second, the flywheel stabilizes rotational motion of the crankshaft by counteracting the inertia. Third, the rotational motion of the flywheel is transferred to the clutch. Fourth, the transmission shaft and driveshaft regulate and stabilize the engine output through the differential gears.
