Abstract: In a clutch throwout, particularly for automotive clutches, a self-centering clutch bearing is arranged on or in a sliding sleeve. The stationary bearing ring of the clutch bearing is connected with the sliding sleeve via an intermediate element, which features guides for the radial sliding, in two mutually crossing radial directions, of the clutch bearing in relation to the sliding sleeve.To enable the clutch bearing to slide in any radial direction and to position itself precisely centered in relation to the tongue ends of the clutch diaphragm spring, without great constraining forces, while, regardless of position, damping the relative movements of clutch bearing in relation to sliding sleeve, intermediate element is radially interlocked with the stationary bearing ring and with the sliding sleeve, in two mutually crossing directions.

Abstract: In a clutch release bearing, wherein a pressure plate is affixed to a sliding sleeve, the pressure plate has a cylindrical portion affixed to the sleeve, a radial flange adapted to abut the bearing of the device, and an intermediate conical section. The conical section has four recesses distributed thereabout, two of which are adapted to engage projections of a clutch lever. A holding ring is held on the cylindrical portion of the pressure plate, and has projections entering the other two recesses of the pressure plate. Recesses in the holding ring aligned with the first mentioned recesses have tongues adapted to resiliently hold the projections of the clutch lever in the respective recesses.

Abstract: A clutch throw-out device has a thrust bearing and a pressure plate. A radially extending flange on one of the bearing rings of the thrust bearing is coupled to the pressure plate, to inhibit relative rotation therebetween. The coupling includes projections on one of the flange or pressure plate extending into corresponding recesses of the other member at the coupling. The recesses are adequately large to permit radial movement, and elastic damping means are provided at least between the recesses and projections.
