Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A clutch release bearing for interposition between the clutch elements and the clutch release operating mechanism having a central axis of rotation comprising an outer race ring adapted to be connected to the clutch operating mechanism, an inner race ring, and a plurality of bearing elements located therebetween, said race rings having race surfaces lying parallel to the axis of rotation, the race surface of said inner race ring lying radially within the outer race ring, said inner ring having a radial extension, said bearing including means abutting the extension of said inner race ring and being adapted to engage the clutch elements, said engaging means and the extension of said inner race ring having correspondingly curved abutting surface permitting relative sliding movement therebetween angularly of the axis of rotation.
Claim 2
Dependent Claim
130 words
A clutch release bearing for interposition between the clutch elements and the clutch release operating mechanism having a central axis of rotation comprising an outer race ring adapted to be connected to the clutch operating mechanism, an inner race ring, and a plurality of bearing elements located therebetween, said race rings having race surfaces lying parallel to the axis of rotation, the race surface of said inner race ring lying radially within the outer race ring, said inner ring having a radial extension, said bearing including means abutting the extension of said inner race ring and being adapted to engage the clutch elements, said engaging means and the extension of said inner race ring having correspondingly curved abutting surface permitting relative sliding movement therebetween angularly of the axis of rotation.
