Introduction

The clutch disc is the central connecting element of the clutch. It forms a friction system between the engine, flywheel and the clutch pressure plate. With the clutch engaged, it is pressed between the flywheel and clutch pressure plate and actuated by friction. It transmits the drive torque to the transmission input shaft through the hub splines.

In modern vehicles, only clutch discs with torsion dampers and spring-loaded facings are used. Organic friction facings are used almost without exception in car construction. Ceramic-metal sintered facings are used primarily for special vehicles and tractors.
