Embodiment Construction

[0028] figure 1 The shown device 1 comprises a hydraulic control unit comprising a stationary support 2, usually mounted on the casing of the gearbox (not shown). The control part also comprises a piston 3 entirely housed in an annular cavity 4 provided in the support 1 and designed to house the control hydraulic fluid fed through the device 5 . The piston 3 is equipped with two sealing washers 6 and 7 in contact with the radially inner wall 8 and the radially outer wall 9 of the cavity 4 respectively.

[0029] The device 1 also includes a bearing 20 forming a clutch-disengage thrust bearing, having an inner ring referenced 22 and an outer ring referenced 24 . A row of balls 26 is held positioned in the space defined between rings 22 and 24 by cage 28 .

[0030] The axes of symmetry of rings 22 and 24 are defined by X 22 and x 24 Indicates that these axes coincide with each other when the bearing 20 is in the assembled configuration.

[0031] The bearing 20 also includes ...

Abstract

A bearing (20) forms a clutch-disengage thrust bearing of a motor vehicle and comprises an inner ring (22), an outer ring and rolling elements (26). The flange (100) mounted on the inner ring (22) is equipped with two serrated series of flange segments (110, 118) extending radially on the same side of the flange's cylindrical web (116) and with respect to the inner The axis of symmetry (X22) of the ring is angularly offset and axially offset along said axis. In addition to this bearing, the device comprises a control device (2, 3, 50) provided with a stationary part (2) and a moving part (3, 50) mounted for axial movement and suitable for To make the bearing (20) move relative to the clutch mechanism, the device also includes a protective telescoping part (80), which is arranged between the stationary part and the bearing. The flange segments (110, 118) define therebetween an annular space that receives and clamps one edge (82) of the telescoping portion (80).

Description

technical field [0001] The invention relates to a bearing forming a thrust bearing of a motor vehicle clutch. The invention also relates to a clutch device comprising a bearing of the type described above. Finally, the invention relates to a motor vehicle equipped with said bearing or said clutch device. Background technique [0002] In the automotive industry, it is known to constitute a clutch-disengage thrust bearing using a bearing comprising an inner ring, an outer ring and rolling elements so as to make it possible to control a diaphragm spring as a actually known disengagement mechanism. Such a bearing may be incorporated in a clutch drive, for example as disclosed in FR-A-2740193. In this device, the telescoping part is used to isolate the parts moving relative to each other from the outside, in particular the control piston which moves the inner ring of the bearing axially and the pre-compression spring of the pre-compressed bearing from the outside. In order to ...
