Release-or engaging device for frictional clutches in motor vehicle drives, has centering unit formed by release-or engaging bearing, and bearing rings whose rolling path is in non-positive engagement with rolling elements in bearing

摘要

The device has an actuating element axial-movably arranged in a clutch housing (12) and including a release-or engaging bearing (36) with two bearing rings (36a, 36c) and intermediately processed rolling elements (36b). A rotatable clutch element of a frictional clutch is connected with the rolling elements. A centering unit centers the release-or engaging bearing relative to the rotatable clutch element, and is formed by the release-or engaging bearing. A rolling path of the bearing rings is in non-positive engagement with the rolling elements in the release-or engaging bearing.
