Abstract

The device (1) has a clutch cover (2) comprising multiple tab portions (3) that are spaced from each other in a circumferential direction (U). A position of a wire coil (4) is defined in a radial direction (R) by the tab portions for formation of a tilting bearing. A lever element (5) is tiltably supported by the tab portions and the wire coil for engaging and / or disengaging the device by axial shifting of a pressing plate (6). The wire coil comprises two embossings (7a), where edges (8a) of the embossings are brought in contact with the tab portions or a tolerance-afflicted system.

Description

technical field [0001] The invention relates to a clutch arrangement according to the preamble of claim 1 . Background technique [0002] Document DE 44 20 251 A1 discloses a clutch arrangement according to the preamble of claim 1 . The clutch device has a clutch cover, two wire rings, the clutch cover has a plurality of web segments spaced apart from one another in the circumferential direction, the position of the wire rings is defined in the radial direction by way of the web segments for forming a pivot bearing. Sure. Furthermore, the clutch device has a disk spring, which is pivotably mounted via the web and via the two wire rings for engaging and disengaging the clutch device by axially displacing the pressure plate. [0003] When the wire ring is configured as an open wire ring, so-called locking tabs are used which engage between the two ends of the open wire ring and prevent the wire ring from Movement in the circumferential direction of the clutch device, i.e. p...
