ABSTRACT:
A shiftable friction clutch, in particular for gear drives, includes a gearshift sleeve axially movably supported on the shaft to be coupled and comprising at least one axially movable friction ring which belongs to one clutch half, which through clutch friction surfaces cooperates with the other clutch half and which is supported on the shaft to be coupled through rolling members to produce a contact pressure depending on the torque by means of sloped surfaces inclined with respect to the plane of rotation. To make shifting easier, in particular the disengagement, the sloped surfaces are provided on at least one element which is rotatable relative to the shaft and which is arranged in a corresponding recess in the shaft and can be moved against a spring force acting in direction of rotation of the shaft.
