4462305025 ZF O.CLUTCH DISC

An Outer Clutch Disc, part of the Piston Ring Set, plays a vital role in the clutch system of vehicles. Its primary function is to ensure smooth engagement and disengagement of gears, particularly in high-performance or heavy-duty driving conditions. This piston ring set boasts improved fuel efficiency and reduced wear on other components due to its precise fitment and reliable operation. 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.
