This Outer Clutch Disc from
ZF is designed to handle the demands of high-performance driving. It is commonly used in vehicles that require quick acceleration and rapid shifting, such as sports cars or trucks with heavy payloads. The clutch disc offers improved thermal resistance, increased wear life, and enhanced overall performance.
Clutch discs are circular friction plates integral to manual transmission vehicles, positioned between the engine flywheel and pressure plate. Their primary function is to transmit engine torque to the transmission input shaft when engaged, enabling gear changes. Core construction utilizes a steel center hub splined to the input shaft, faced with friction material riveted or bonded to both sides. Dampening springs or torsional dampers are commonly incorporated to mitigate driveline vibrations and noise. Variations exist based on spline count, diameter, friction material composition, and damping technology, dictated by vehicle and transmission specifications.
