Abstract

A friction clutch, particularly for a motor vehicle, has a rotatable clutch disk which is connected to a transmission input shaft so as to be fixed with respect to rotation relative to it and which can be clamped in axially between two clutch pressure plates. The pressure plates, which may be a clutch pressure plate and a flywheel, have annular friction surfaces which can act upon the clutch disk. The annular friction surfaces comprise the friction surfaces of a plurality of friction segments which are arranged in a uniformly distributed manner so as to form a ring, wherein every friction segment is arranged so as to be axially flexible in a springing manner to a certain extent.
