Problems solved by technology

[0002] A problem in clutch release systems is that the axis of rotation of the release bearing and the center axis of the separator can have angular misalignment and / or axial misalignment
[0004] The solutions known from the prior art require additional components, in particular the sheet-metal cap for fastening the release bearing to the release has to be produced as an additional stamped part and crimped during assembly, thus requiring additional work in production step

Embodiment Construction

[0018] figure 1 A sectional view of the clutch release 1 of the present invention is shown. The clutch release 1 includes a release housing 2 and a release bearing 3 . The release bearing 3 includes a bearing outer ring 4 and a bearing inner ring 5 . The bearing inner ring has a hollow-cylindrical projection 6 extending away from the separator housing 2 in the axial direction and having a surrounding nose 7 at its axial end. The surrounding nose 7 is formed by a conical bevel 8 and an essentially radially extending edge 9 . The surrounding lugs 7 allow a form-locking connection of the snap-fit ​​type with a contact plate 10 which has a disk-shaped opening and is elastic or two-part in radial direction for assembly. The contact plate 10 is in the installed position of the clutch release 1 with the figure 1 For clutch actuation, the disk spring, not shown, is in contact with the rear side of the contact plate 10 provided with the reference numeral 11 , wherein the clutch is ...

Abstract

For a release unit (1) for a pull-type clutch, comprising a release unit housing (2) and a throwout bearing (3) having an outer bearing ring (4) and an inner bearing ring (5), wherein the outer bearing ring is fastened to the release unit housing and the inner bearing ring has means for applying a tensile force to a disk spring in order to actuate the clutch, simple assembly is enabled by having parts of the outer bearing ring engage with a part of the release unit housing designed as a plate (14) from behind so as to have radial play, wherein a spring element (21) is arranged between the outer bearing ring and the release unit housing, said spring element applying a pre-loading force to the outer bearing ring in the axial direction with respect to the release unit housing.

Description

technical field [0001] The invention relates to a separator for a pull clutch, comprising a separator housing and a release bearing, the release bearing having a bearing inner ring and a bearing outer ring, wherein the bearing outer ring is fixed to the separator The housing and said bearing inner ring include means for loading the disc springs in tension for clutch actuation. Background technique [0002] A problem in clutch release systems is that the rotational axis of the release bearing and the center axis of the release can have angular and / or axial misalignment. It is therefore necessary to provide means which in particular can compensate for the axial misalignment, since otherwise large forces would be transmitted from the disc spring via the release bearing to the separator and subsequent actuating means such as central release on the slave cylinder piston of the device. [0003] A decoupler is known from EP 1 369 611 A1, which has a device for compensating errors...
