Abstract
Abstract A composite clutch release bearing assembly including a tubular bearing carrier having an annular collar disposed in frictional engagement on one end thereof and interlocked to prevent relative rotation and outward axial movement of the collar relative to the carrier. A thrust-type bearing is disposed with its stationary race member in frictional engagement on the other end of said tubular carrier preventing axial outward movement of the bearing along the other end of said carrier. The bearing is positioned with the inner face of the stationary race in abutting relationship against the inner edge of the collar and the collar is further provided with a radially extending flange including engaging means for coacting with the clutch actuation mechanism.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
141 words
A clutch release bearing assembly comprising a tubular bearing carrier, an annular collar disposed in frictional engagement around one end portion of said carrier and terminating in an annular radial edge and formed with a radially extending flange axially spaced from said edge, interlocking means on said collar and said carrier for preventing relative rotation therebetween and outward axial movement of said collar along said one end portion, a bearing supported by said carrier including a rotatable race, a stationary race and a plurality of antifriction elements constrained therebetween, said stationary race having an inner radial face and an axially spaced outer radial face and formed with an axial bore disposed in frictional engagement around the other end portion of said carrier, said stationary race positioned with said inner face in axial abutting relationship against said radial edge of said collar.
Claim 2
Dependent Claim
141 words
A clutch release bearing assembly comprising a tubular bearing carrier, an annular collar disposed in frictional engagement around one end portion of said carrier and terminating in an annular radial edge and formed with a radially extending flange axially spaced from said edge, interlocking means on said collar and said carrier for preventing relative rotation therebetween and outward axial movement of said collar along said one end portion, a bearing supported by said carrier including a rotatable race, a stationary race and a plurality of antifriction elements constrained therebetween, said stationary race having an inner radial face and an axially spaced outer radial face and formed with an axial bore disposed in frictional engagement around the other end portion of said carrier, said stationary race positioned with said inner face in axial abutting relationship against said radial edge of said collar.
Claim 3
Dependent Claim
20 words
The bearing assembly as defined in claim 1 in which said collar is integrally formed with said radially extending flange.
Claim 4
Dependent Claim
24 words
The bearing assembly as defined in claim 1 in which said collar comprises a plurality of circumferentially spaced arcuate segments supported by said flange.
Claim 5
Dependent Claim
38 words
The bearing assembly as defined in claim 1 in which said interlocking means comprises a radially offset section on said one end portion of said collar disposed in engaging relationship within a circumferential gap formed in said collar.
Claim 6
Dependent Claim
27 words
The bearing assembly as defined in claim 1 including two diametrically disposed offset sections disposed in engaging relationship within two diametrically disposed circumferential gaps in said collar.
Claim 7
Dependent Claim
29 words
The bearing assembly as defined in claim 1 in which said inner radial face of said stationary race intersects said bore in the form of a rounded annular edge.
Claim 8
Dependent Claim
43 words
The bearing assembly as defined in claim 1 wherein said carrier is comprised of a rolled metal sheet having the longitudinal edges thereof disposed in abutting relationship and means along said longitudinal edges for interlockingly engaging and retaining said edges in abutting relationship.
Claim 9
Dependent Claim
33 words
The bearing assembly as defined in claim 1 in which the internal surface of said tubular bearing carrier is formed with at least one cavity adapted to receive and retain a lubricant therein.
Claim 10
Dependent Claim
28 words
The bearing assembly as defined in claim 1 further including engaging means on said flange for releasably engaging actuating means for effecting axial movement of said bearing assembly.
Claim 11
Dependent Claim
18 words
The bearing assembly as defined in claim 1 in which said bearing is of the axial thrust type.
Claim 12
Dependent Claim
26 words
The bearing assembly as defined in claim 1 in which said frictional engagement of said stationary race on said carrier is achieved by a press fit.
Claim 13
Dependent Claim
34 words
The bearing assembly as defined in claim 1 in which said frictional engagement of said stationary race on said carrier is achieved by staking the periphery of said carrier adjacent to said stationary race.
Claim 14
Dependent Claim
73 words
The bearing assembly as defined in claim 1 in which said outer radial face intersects said bore of said stationary race in the form of a sharp annular edge, and said frictional engagement of said stationary race on said carrier is achieved by a press fit with said annular edge disposed in engaging relationship with the periphery of said carrier to prevent outward axial movement of said bearing along said other end portion.
