Embodiment Construction

[0031] FIG. 1 shows the release bearing 1 in the mounted state. In this case, the inner bearing ring 2 is connected in a rotationally fixed manner to an actuating device 3 which surrounds a transmission shaft (not shown in FIG. 1 ), which connects the internal combustion engine to the gear transmission. For coupling and decoupling, the handling device 3 is axially movable as indicated by the double arrow. Rolling bodies 5 arranged at a distance in a cage 6 are guided between the inner bearing ring 2 and the associated further outer bearing ring 4 . On the outer side of the outer bearing ring 4, an adjusting ring 7 is mounted, which forms a radially inward ring flange 8, on which a spring element 9, in particular a disk spring, of the transmission clutch is supported with appropriate force. As a result of this arrangement, both the adjustment ring 7 and the outer bearing ring 4 are set in rotation with the transmission separation clutch. In order to compensate coupling shocks...

Abstract

The invention relates to a disengagement bearing (1) for a shift separation clutch. The disengagement bearing (1) comprises a rotationally fixed inner bearing ring (2) and an associated peripheral bearing ring (4) on which an adjustment ring (7) is supported externally by means of a contact area (10). In order to reduce abrasion, the spherical contact area (10) is provided with a hard material coating.

Description

technical field [0001] The invention relates to a release bearing specially used for a transmission release clutch, which is arranged between an internal combustion engine and a gear transmission in the installed state. The release bearing or clutch release bearing is the part of the operating device with which the transmission release clutch can be engaged or disengaged. The release bearing, which is designed as a shoulder bearing, comprises a first rotationally fixed bearing ring, which is positioned on the actuating device by means of a ring flange. The second rotary bearing ring of the release bearing likewise has a ring flange which interacts indirectly or directly with the spring element of the transmission release clutch. The rolling elements of the release bearing, which are guided between the bearing rings, are housed in a cage. Background technique [0002] During the operation, engagement and disengagement of the transmission separation clutch, the clutch releas...
