ABSTRACT:
An electromagnetically operable friction disk clutch having a electromagnet as well as having a rotor and an armature element to which the electromagnet can apply a magnetic field for interaction of the rotor and armature element, the armature element being arranged on a resting means which moves the armature element along a rotation axis of the rotor by magnetic force through a movement distance to a stop position on the rotor, and returns elastically without any magnetic forces to a position in which the armature element and the rotor can move, with respect to one another, without touching. According to the invention the resetting means comprise not only an elastic component but also a plastic component which at least partially compensates for the increase in the original movement distance resulting from wear by plastic deformation of the resetting means.
