Abstract

A multi-disk clutch having a plurality of interengaging disks movable along a longitudinal clutch axis and a resetting device for the mutual release of adjacent disks along a release distance, with the release distance being bounded by an abutment device. The abutment device includes at least one contact section of a clutch part movable along the longitudinal clutch axis and at least one contact section of an axially fixed clutch part, with the moving clutch part and the axially fixed clutch part having different thermal coefficients of expansion and with the contact sections at both sides cooperating such that the bounding of the release distance varies in dependence on the temperature, with at least one of the contact sections having a sloping surface.
