Abstract

A maintained self-centering clutch release bearing comprises an operating sleeve moved axially by clutch release control means. There is radial clearance between the sleeve and a bearing comprising a non-turning race, a turning race and rolling members between the races. A clutch cover assembly operating boss is fastened to the turning race. There are respective and adjacently disposed rims on the non-turning race and the operating sleeve, both perpendicular to the axial direction. An elastic clamping ring bears against bearing means on the operating sleeve and acts axially on the rim of the non-turning race to urge its rim axially towards the rim of the operating sleeve, so that the rims are clamped axially together, with friction. This assembles together the bearing and the operating sleeve and provides for maintained self-cerntering of the clutch release bearing relative to the clutch cover assembly. The bearing means on the operating sleeve comprise annular radially projecting means locally interrupted by at least one passage means featuring an engagement ramp surface. The elastic clamping means comprise radial lugs adapted to pass through the passage means and bearing on the e…
