ABSTRACT:
A release device for a friction clutch includes a guide tube, a sliding sleeve mounted on the guide tube, and a release bearing mounted coaxially to the sliding sleeve, the bearing including a first bearing race, rolling elements, and a rotating second bearing race. The second bearing race supports a connecting element, which establishes the working connection between the release bearing and the ends of spring tongues of a diaphragm spring, which serves as the actuating element of the friction clutch. The connecting element has a receiving section, which holds the ends of the diaphragm spring tongues and can shift position in the radial direction in opposition to a restoring force, and a retaining section for the second bearing race. Radial is placement of the ends of the diaphragm spring tongues which occurs upon axial actuation of the releasing device can be absorbed by the connecting element with essentially no friction.
