Abstract

A clutch disc for a motor vehicle clutch which has an input part and an output part with relative rotational play. A friction device is located between the input part and output part. The friction device includes a friction disc located non-rotationally on the input part or on the output part, which friction disc has friction areas which have different coefficients of friction around its periphery, There also are contact areas which in the effective range of angular rotation of the clutch disc move essentially from one friction area at least partly to another friction area.
