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