Abstract
Abstract A clutch release bearing is disclosed comprising an operating element having a transverse annular flange, a bearing plate lining one side of the annular flange and clips being provided for a relative elastic snap-fit engagement on the associated clutch fork. The clips are independent, generally U-shaped parts having a bight portion which is interposed between the bearing plate and the transverse annular flange of the operating element under a radial lug of the bearing plate. Alternatively, the bight portion extends on the side of the transverse annular flange remote from the bearing plate.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
A clutch release bearing comprising an operating element operable by a clutch control member, and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange, a bearing plate overlying said transverse annular flange for contact with the clutch control member, and clips having elastically deformable lateral wings with a bight portion therebetween for providing an elastic snap-fit engagement of said clutch release bearing on the clutch control member, each of said clips defining an independent, generally U-shaped part, said bearing plate having lugs extending between said lateral wings of each respective clip and relatively adjacent said bight portion of each clip.
Claim 2
Dependent Claim
114 words
A clutch release bearing comprising an operating element operable by a clutch control member, and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange, a bearing plate overlying said transverse annular flange for contact with the clutch control member, and clips having elastically deformable lateral wings with a bight portion therebetween for providing an elastic snap-fit engagement of said clutch release bearing on the clutch control member, each of said clips defining an independent, generally U-shaped part, said bearing plate having lugs extending between said lateral wings of each respective clip and relatively adjacent said bight portion of each clip.
Claim 3
Dependent Claim
54 words
A clutch release bearing according to claim 1, wherein said operating element has a pair of axial bosses receiving each of said clips for circumferential retention of said clutch release bearing to the clutch control member, and said wings of each clip extends axially between and in contact with respective pairs of said bosses.
Claim 4
Dependent Claim
35 words
A clutch release bearing according to claim 2, wherein at least one of said wings of each clip has a transversely turned back free end in contact with a portion of the corresponding axial boss.
Claim 5
Dependent Claim
25 words
A clutch release bearing according to claim 3, wherein additional engaging means are provided between said at least one wing and its corresponding axial boss.
Claim 6
Dependent Claim
48 words
A clutch release bearing according to claim 4, wherein the said at least one wing is elastically snapped on said corresponding axial boss and said at least one wing has a projection in engagement in a recess formed in the adjacent side of the said corresponding axial boss.
Claim 7
Dependent Claim
30 words
A clutch release bearing according to claim 2, wherein a right-angled flange is provided along an edge of each of said wings and extends outwardly of its corresponding axial boss.
Claim 8
Dependent Claim
21 words
A clutch release bearing according to claim 2, wherein said bearing plate has notches for axial engagement of said axial bosses.
Claim 9
Dependent Claim
69 words
A clutch released bearing according to claim 1, further comprising a cover for axially connecting said drive element to said operating element, said cover having a front wall defining axially acting resilient means for bearing against said drive element, and a plurality of lugs for engagement with hook-shaped projections fixed relative to said operating element, said hook-shaped projections being peripherally spaced along and integral with said transverse annular flange.
Claim 10
Dependent Claim
36 words
A clutch release bearing according to claim 1, wherein said transverse annular flange has recess means axially set back relative to its front surface in contact with said bearing plate, for insertion of said bight portions.
Claim 11
Dependent Claim
116 words
A clutch release bearing comprising an operating element operable by a clutch control member and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange lined on its surface by a bearing plate for contact with said control member, and clips having elastically deformable lateral wings and providing elastic snap-fit engagement of said clutch release bearing on said control member, each of said clips defining an independent, generally U-shaped part, the bight portion of each of said U-shaped parts being interposed between said bearing plate and said transverse annular flange of said operating element, under a radial lug defined by said bearing plate.
Claim 12
Dependent Claim
116 words
A clutch release bearing comprising an operating element operable by a clutch control member and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange lined on its surface by a bearing plate for contact with said control member, and clips having elastically deformable lateral wings and providing elastic snap-fit engagement of said clutch release bearing on said control member, each of said clips defining an independent, generally U-shaped part, the bight portion of each of said U-shaped parts being interposed between said bearing plate and said transverse annular flange of said operating element, under a radial lug defined by said bearing plate.
Claim 13
Dependent Claim
39 words
A clutch release bearing according to claim 10, wherein said transverse annular flange has recess means axially set back relative to its front surface remote from the surface in contact with said bearing plate, for receiving said bight portions.
Claim 14
Dependent Claim
120 words
A clutch release bearing comprising an operating element operable by a clutch control member and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange lined on its surface by a bearing plate for contact with said control member, and clips having elastically deformable lateral wings and providing elastic snap-fit engagement of said clutch release bearing on said control member, each of said clips defining an independent, generally U-shaped part, the bight portion of each of said U-shaped parts being disposed on the side of said transverse annular flange facing towards said drive element, said lateral wings passing through said transverse annular flange and said bearing plate.
Claim 15
Dependent Claim
120 words
A clutch release bearing comprising an operating element operable by a clutch control member and a drive element actuable by said operating element and cooperable with a clutch release mechanism, said operating element comprising a transverse annular flange lined on its surface by a bearing plate for contact with said control member, and clips having elastically deformable lateral wings and providing elastic snap-fit engagement of said clutch release bearing on said control member, each of said clips defining an independent, generally U-shaped part, the bight portion of each of said U-shaped parts being disposed on the side of said transverse annular flange facing towards said drive element, said lateral wings passing through said transverse annular flange and said bearing plate.
Claim 16
Dependent Claim
50 words
A clutch release bearing according to claim 12, wherein at least one of said wings comprises a transverse shoulder bearing on the side of said bearing plate remote from said transverse annular flange for at least participating in the axial retention of said bearing plate against said transverse annular flange.
