Abstract

This invention relates to a friction clutch with a membrane spring in a pulled or pushed clutch, in which there is a second membrane spring/plate spring which assists the release force, and which, when the friction clutch is engaged, exerts little or no release force, and generates a release force which increases with increasing release travel.
