Friction clutch with automatic wear compensation

摘要

A friction clutch having a wear compensation device is provided that includes a cover assembly that is secured to a flywheel of an internal combustion engine for rotation therewith. A pressure plate is arranged in the cover assembly and is urged by a spring member toward the flywheel. At least one friction plate is arranged between the pressure plate and the flywheel enabling the pressure plate to provide a clamping force to press the friction plate against the flywheel. The wear compensation device includes two cooperating annular members that are changeable along their axial dimension to compensate for the increased distance between the pressure plate and the friction plate due to wear in the clutch.
