Abstract
Abstract A clutch bearing assembly has inner and outer rings defining a race for ball bearings. The outer ring is adapted to engage a clutch lever, and the inner ring is adapted to be a stationary ring. A sliding sleeve for the assembly is coupled to the inner ring by deformable elements positively affixed to one of these members. The deformable elements may be wire bights having their ends axially inserted in grooves in the inner ring and sliding sleeve. Alternatively, the deformable element may be a spiral spring radially engaging an axial extension of the inner ring and having ends inserted in axially extending holes in the sliding sleeve.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
89 words
In a clutch bearing assembly having a bearing with first and second rings defining races for rolling bearing elements, a sliding sleeve, and means coupling said sliding sleeve to said second ring, the improvement wherein said coupling means comprises permanently deformable holding means intercoupling said second ring and sliding sleeve for permitting displacement of said second ring with respect to said sleeve in all radial directions while inhibiting relative rotation therebetween, said deformable holding means being positively connected to at least one of said second ring and sliding sleeve.
Claim 2
Dependent Claim
89 words
In a clutch bearing assembly having a bearing with first and second rings defining races for rolling bearing elements, a sliding sleeve, and means coupling said sliding sleeve to said second ring, the improvement wherein said coupling means comprises permanently deformable holding means intercoupling said second ring and sliding sleeve for permitting displacement of said second ring with respect to said sleeve in all radial directions while inhibiting relative rotation therebetween, said deformable holding means being positively connected to at least one of said second ring and sliding sleeve.
Claim 3
Dependent Claim
38 words
The clutch bearing assembly of claim 1 wherein said deformable holding means comprises deformable bight means extending from the periphery of said bearing and sliding sleeve and positively affixed to said second ring and to said sliding sleeve.
Claim 4
Dependent Claim
84 words
The clutch bearing assembly of claim 2 further comprising a plurality of radially extending grooves in the face of said second ring toward said sliding sleeve, and a plurality of radially extending grooves in the face of said sliding sleeve away from said second ring, the grooves of said second ring and sliding sleeve being axially aligned, and wherein said bight means comprises deformable U-shaped members having opposite ends fixedly held in respective axially aligned grooves in said second ring and said sliding sleeve.
Claim 5
Dependent Claim
44 words
The clutch bearing assembly of claim 1 wherein said deformable holding means comprises a coil having its ends affixed to one of said sliding sleeve and second ring and the central portion thereof wound around the other of said sliding sleeve and second ring.
Claim 6
Dependent Claim
57 words
The clutch bearing assembly of claim 4 wherein said second ring has a shoulder with spiral grooves, and diametrically opposed radially extending slits in said shoulder, said coil engaging said spiral grooves and extending radially inwardly into said slits, and thence axially toward said sliding sleeve, the ends of said coil being affixed in said sliding sleeve.
Claim 7
Dependent Claim
28 words
The clutch bearing assembly of claim 1 wherein said first ring is an outer bearing ring, and said second ring is an inner bearing ring of said bearing.
Claim 8
Dependent Claim
17 words
The clutch bearing assembly of claim 1 wherein said deformable holding means comprises wire of arbitrary cross-section.
