Clutch release bearing

A clutch release bearing assembly of the kind comprising an operating element adapted to be acted upon by a control member such as a disengaging fork, which operating element is carried by a support member mounted for axial movement, and an actuator comprising an extensionpiece which under the effect of the operating element is adapted to act on the disengagement mechanism of a clutch, wherein said actuator is mounted for axial sliding movement over support guide means, and swivel means are provided between said actuator and said support guide means, and swivel means comprising an annular bead having a rounded section in the axial direction projecting radially from the outer surface of the support guide for contact with said actuator.

A clutch release bearing assembly of the kind comprising an operating element adapted to be acted upon by a control member such as a disengaging fork, which operating element is carried by a support member mounted for axial movement, and an actuator comprising an extension piece which under the effect of the operating element is adapted to act on the disengagement mechanism of a clutch, wherein said actuator is mounted for axial sliding movement over support guide means and swivel means are provided between said actuator and said support guide means, said actuator comprising an axial wall and, at each end thereof, a radial flange, one of said radial flanges being adapted to cooperate with a bearing element disposed axially between said operating element and said actuator, and the other of said radial flanges being adapted to cooperate with the disengagement mechanism, and at least one of said radial flanges forming a part which is separate from the associated axial wall and suitably mounted thereon.

A clutch release bearing assembly comprising an operating element adapted to be controlled by a control member, a support member mounted for axial movement, said operating element carried by said support member for movement therewith, an actuator defining an axial extension responsive to axial movement of said operating element and adapted to be disposed axially between said operating element and a clutch disengagement member for operating the latter, a support guide axially slidably mounting said actuator, swivel means provided on a selected one of said actuator and said support guide for swivel contact with the nonselected one of said actuator and said support guide to compensate for lack of parallelism between said support member and said support guide.
