Abstract

A friction clutch for motor vehicles with a ring-shaped pressure plate with a more-or-less radially oriented, ring-shaped friction surface, which can be moved axially against a ring-shaped friction lining carried by a support plate. The ring-shaped friction surface consists of a radially inner, ring-shaped partial friction surface and an adjoining radially outer ring-shaped partial friction surface. The radially outer partial friction surface projects axially to a slight extent beyond the radially inner partial friction surface.
