Abstract
A self-centering thrust bearing assembly, in which the bearing comprises one ring intended to cooperate with a driving unit of the clutch assembly, whereas its other ring is mounted on an axial movable support driven for the clutching operation, said mounting being provided with a certain radial clearance and a resilient pinching action in axial sliding rest on said support. The pinching action is substantially carried out by first fastening means exerting a pinching stress localized from the ring to the support so that it constitutes for the ring the center of a pivoting movement which is superposed to the radial sliding clearance for the self-centering process.
Claims3
A self-centering thrust bearing assembly for a clutch including a driving unit, said assembly comprising:
- two bearing rings with interposed rolling members, the first of said rings being intended to cooperate axially with said driving unit of said clutch;
- an axially movable support sleeve with a flange, driven for the clutching operation, said second ring being mounted in sliding contact with said support sleeve with a certain radial freedom for the self-centering process;
- and
- resilient fastener means, said fasterner means being provided to exert a pinching stress on said second ring and said axially movable support sleeve, respectively, in order to maintain sliding contact between said second ring and said axially movable support sleeve, said resilient fastener means comprising:
- two diametrically opposed fastening members exerting, respectively, a different pinching stress on said second bearing ring and said axially movable support sleeve so that the first of said fastening members constitutes a center of pivoting movement for said second bearing ring.
