Abstract
Multiple-disk clutch with outer disks supported by an outer disk carrier that is rotatable around an axis of rotation and with inner disks supported by an inner disk carrier that is rotatable around the axis of rotation. The outer disks and the inner disks form an annular disk stack with an inner radius and an outer radius. An axially movable actuator actuates the disk stack. The actuator engages in a central radius area of the disk stack with reference to the axis of rotation when actuating. The disk stack includes a resilient element.
