Abstract
A structurally and/or functionally improved friction clutch device is disclosed. In particular, a servo spring for a clutch is to be provided which is suitable for series production. In particular, the servo spring is to be realized in the clutch while integrating already existing components. In particular, the servo spring is to keep a maximum disengaging force low. In particular, the servo spring is to operate only under worn conditions; in the new state and during separation it should be possible for it to be force-free. In particular, the total tolerance in the friction clutch device is to remain small, so that the susceptibility of the servo spring force to tolerance deviations is limited.
Claims9
A friction clutch device comprising:
- an axis of rotation;
- a housing;
- at least one contact plate axially movable relative to the housing for actuation between an engaged actuation position and a disengaged actuation position;
- a first spring for providing a load to the at least one contact plate and comprising an opening;
- at least one spacing element to support the first spring on the housing;
- a support ring, axially supported on the at least one spacing element in the disengaged actuation position, comprising:
- a flat basic form;
- and,
- at least one support contour protruding from the flat basic form, extending through the opening, and supporting the support ring on the at least one spacing element;
- and,
- a second spring comprising a first support radius and a second support radius, wherein the second spring is:
- arranged to reduce an actuating force;
- positioned between the housing and the first spring;
- supported on the housing at the first support radius;
- and,
- supported directly on the support ring at the second support radius.
