Abstract
A clutch-release mechanism for actuating the friction clutch of a motor vehicle, installed concentrically around a guide sleeve, includes a release bearing with an inner ring and an outer ring as well as a sliding sleeve. The inner ring is in working contact with a release spring of the friction clutch and the outer ring is in working contact with the sliding sleeve by way of a sliding surface, and the release mechanism has both a first device for compensating for a tilt of the center axis of the friction clutch with respect to the center axis of the guide sleeve and/or for a wobbling eccentricity of the release spring, and a second device for compensating for an offset between the above-mentioned center axes. The first device consists of a modified raceway for the balls, where the race has both a first race radius and a second race radius to form a surface in the form of a spherical segment, where differences between the angles of the release spring and of the release bearing are compensated. Because the raceway can be produced in any case with high precision in the outer ring and because the rolling contact of the parts is lubricated with grease and protected from the outside environment by seals, no additional components are required for the release mechanism, and there are no additional friction points to be lubricated and sealed.
