Abstract

This invention relates to a self-aligning clutch release bearing assembly comprising a rolling element bearing having a rotary race which in use engages with a clutch member, and a non-rotary race mounted on a support for transmission of a clutch release load. The non-rotary race is relatively movable on the support transversely to the rotary axis of the bearing assembly to permit in use self-alignment of the rotary axis of the bearing with rotary axis of the clutch member. This movement is controlled by a layer of viscous material interposed between the support and the non-rotary race. The viscous material exhibits some resilience and up to a given value resistance to plastic flow so that the material locates the non-rotary race but allows it to move to achieve self-alignment on operation of the clutch in use.

Claims9

Dependent claims

A self-aligning clutch release bearing assembly comprising:

a rolling element bearing having a rotary race and a non-rotary race, said non-rotary race including a part having an axially directed face;
support means on which the bearing is mounted and which permits the non-rotary race to move transversely to the rotary axis of the release bearing assembly so that in use the bearing can align with the rotary axis of the clutch;
and an adhesive viscous material disposed in a space defined between the support means and said axially directed face so as to damp vibration and permit said transverse self-centering movement and being the sole means whereby the rolling element bearing is held in axial assembly to the support means with respective parts of the support means and the axially directed face in direct axial opposition for the transmission of clutch release loads from the support means to the bearing.
