Abstract
Abstract A self centering clutch release bearing assembly having a central axis of rotation includes a supporting member, a first non-rotatable race adapted to be engaged by the clutch shift mechanism and a second rotatable race between which are located a plurality of anti-friction bodies. The first race is mounted on the supporting member to be resiliently movable about a pivot point at an angle thereto. The second race has a spherical surface adapted to engage the clutch release levers. The means for mounting the first race is arranged so that the forces acting upon it lie in a plane intersecting the axis of the bearing at a point, the point forming the pivot of angular movement of the first race and coinciding with the radial center of the spherical surface of the second race.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A self centering clutch release bearing assembly having a central axis, comprising a supporting member, a first non-rotatable race adapted to engage a shift mechanism, means mounting said first race on said supporting member to be resiliently movable about a pivot point at an angle thereto, a second rotatable race, and a plurality of anti-friction bodies rotated therebetween, said second race having a spherical surface adapted to engage a clutch release member, said means for mounting said first race being arranged so that the point forming the pivot of angular movement of said bearing coincides with the center of the spherical surface of said second race and lies on the axis of said bearing in a plane intersecting the axis of said bearing in which the forces acting on said first race lie.
Claim 2
Dependent Claim
133 words
A self centering clutch release bearing assembly having a central axis, comprising a supporting member, a first non-rotatable race adapted to engage a shift mechanism, means mounting said first race on said supporting member to be resiliently movable about a pivot point at an angle thereto, a second rotatable race, and a plurality of anti-friction bodies rotated therebetween, said second race having a spherical surface adapted to engage a clutch release member, said means for mounting said first race being arranged so that the point forming the pivot of angular movement of said bearing coincides with the center of the spherical surface of said second race and lies on the axis of said bearing in a plane intersecting the axis of said bearing in which the forces acting on said first race lie.
Claim 3
Dependent Claim
47 words
The assembly according to claim 1 wherein said supporting member comprises a shaft and the means for mounting said first race comprises a resilient ring interposed between said first race and said shaft, said ring lying in a radial plane transverse to the axis of said shaft.
Claim 4
Dependent Claim
22 words
The assembly according to claim 1 including a clutch release lever having a portion engaging the spherical surface of said second race.
Claim 5
Dependent Claim
27 words
The assembly according to claim 3 wherein the portion of said release lever engaging the second race is concave conforming to the surface of said second race.
Claim 6
Dependent Claim
48 words
The assembly according to claim 1 including a centering ring interposed between the clutch release lever and said second race, said centering ring having a surface conforming to the spherical surface of said second race and resilient means for supporting said centering ring on said clutch release lever.
Claim 7
Dependent Claim
38 words
The assembly according to claim 1 wherein said supporting member comprises a lever pivotally secured to said first race about an axis intersecting the axis of the bearing at the coincident pivot and spherical center of said bearing.
Claim 8
Dependent Claim
15 words
The assembly according to claim 1 wherein said first race comprises the outer bearing race.
