Abstract:
A friction clutch having at least one clutch part (1; 31) which has at least one friction lining (3; 33) with a friction surface (10; 40) which, when the friction clutch is closed, is connected in frictionally engaging fashion to a counterpart clutch part, wherein the friction lining (3; 33) and/or a carrier element (6) of the friction lining (3; 33) is, in a circumferential direction, of undulating shape with wave troughs (20) and wave crests (18, 19), wherein, when the friction clutch is open, the friction lining (3; 33) comes into contact with the counterpart clutch part not with the entire friction surface (10; 40) but only substantially in punctiform fashion in the area of peaks (15-17) of the wave crests (18, 19). The friction lining (3; 33) has reduced friction values locally in the region of the peaks (15-17) of the wave crests (18, 19) in relation to the friction surface (10; 40) surrounding the peaks (15-17) of the wave crests (18, 19).
