Abstract

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