Abstract:
An axial setting device for actuating a multi-plate coupling whose friction plates are alternately connected in a rotationally fast and axially displaceable way to the one and the other respectively of two parts rotatable relative to one another, which rest against an axially fixed supporting disc and which can be loaded by an axially displaceable pressure disc, comprising a housing, a setting disc rotatably supported in said housing and mounted so as to be axially fixed and rotatingly drivable in said housing, said pressure disc supported in said housing in a rotationally fast way by anti-rotation means arranged in said housing and which is axially displaceable in said housing, ball groove configurations in the surfaces of said setting disc and of said pressure disc, which surfaces face one another said ball groove configurations extending in the circumferential direction and having oppositely directed gradients across the circumference and are associated with one another in pairs, so as to jointly accommodate a ball, and rotary driving means for said setting disc mounted in said housing, and wherein said anti-rotation means is designed so as to be releasable from said pressure disc.
