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.

Clutch thrust bearing

In a throw-out bearing for a clutch, a movable element, which may be comprised of a sliding sleeve, is slidably supported on a guide element by flexible conical projections extending inwardly from the movable part to the guide element. The projections may be on the end of and the unitary part of the sliding sleeve, or they may be a part of a sleeve inserted within the sliding sleeve, or they may form a part of the fixed ring of the bearing.

Throw-out bearing for clutches, especially for motor vehicles

A clutch release bearing has a sliding sleeve of a vibration damping and noise insulating material. The sliding sleeve has a flange axially engaging a bearing outer ring, the outer ring being separated from a bearing inner ring by rolling elements. The sliding sleeve has a radially inner sliding surface with axially extending recesses, the recesses extending radially through the end faces of the sliding sleeve.

Clutch release bearing

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.
