ABSTRACT:
A release mechanism for actuating a friction clutch is concentric to a center axis of a guide sleeve mounted in turn on a transmission shaft. The release mechanism includes a clutch release bearing and a device for compensating for the tilt of the center axis of the friction clutch with respect to the center axis of the guide sleeve and/or for the wobbling eccentricity of the release spring. The clutch release bearing includes an inner ring, an outer ring, and an adjusting sleeve. One of the inner ring or outer ring communicates with a release spring of the friction clutch. The device for compensating for the tilt of the center axis of the friction clutch with respect to the center axis of the guide sleeve and/or for the wobbling eccentricity of the release spring includes a release ring and a load ring. The release ring is in contact with a finger of the release spring of the friction clutch and includes a spherical surface having a center on the axis of the transmission shaft. A load ring cooperates with the spherical surface of the release ring and communicates with the adjusting sleeve for placing the one of the inner ring and outer ring in communication with the release spring. Preferably the release ring is curved and the load ring is a circular cross-sectioned wire to reduce wear.
