Abstract
Abstract A clutch disengaging device which includes a sliding sleeve assembly and a self-centering clutch pressure bearing having a stationary bearing ring resting against the sliding sleeve assembly. The clutch pressure bearing is centered in the process of engagement and held by suitable means in a radial direction, such as adhesive means on facing surfaces of the sliding sleeve assembly and the stationary bearing ring for bonding the facing surfaces together.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
108 words
In a clutch disengaging device including a sliding sleeve assembly and a self-centering clutch pressure bearing which includes a stationary bearing ring, the improvement wherein said bearing ring and sliding sleeve assembly comprise first and second adjacent facing alignment surfaces respectively and corresponding first and second adhesive means on both of said alignment surfaces, said two adhesive means being bondable together when said facing alignment surfaces are urged together, said pressure bearing and sliding sleeve assembly and their respective alignment surfaces being radially movable relative to each other for centering said bearing during assembly of this device, and being radially fixed after said adhesive means are bonded together.
Claim 2
Dependent Claim
108 words
In a clutch disengaging device including a sliding sleeve assembly and a self-centering clutch pressure bearing which includes a stationary bearing ring, the improvement wherein said bearing ring and sliding sleeve assembly comprise first and second adjacent facing alignment surfaces respectively and corresponding first and second adhesive means on both of said alignment surfaces, said two adhesive means being bondable together when said facing alignment surfaces are urged together, said pressure bearing and sliding sleeve assembly and their respective alignment surfaces being radially movable relative to each other for centering said bearing during assembly of this device, and being radially fixed after said adhesive means are bonded together.
Claim 3
Dependent Claim
21 words
The clutch disengaging device of claim 1, wherein each of said adhesive means comprises a layer of a microencapsulated bonding agent.
Claim 4
Dependent Claim
18 words
The clutch disengaging device of claim 1, wherein each of said adhesive means is shaped as a dot.
Claim 5
Dependent Claim
28 words
The clutch disengaging device of claim 1, wherein said two adhesive means when bonded together form a double cone having an axis parallel to that of the bearing.
Claim 6
Dependent Claim
14 words
A device according to claim 1 wherein said bonded together adhesive means are elastic.
Claim 7
Dependent Claim
142 words
A clutch disengaging device comprising a sliding sleeve assembly and a self-centering clutch pressure bearing which includes a stationary bearing ring, the improvement wherein said sliding sleeve assembly comprises a first annular part with a first alignment surface thereon facing generally axially, said stationary bearing ring comprises a second annular part with a second alignment surface thereon facing said first alignment surface, holding means for engaging and restraining said first and second annular parts from relative axial movement, and adhesive bonding means secured to at least one of said alignment surfaces and being adhereable to the other when said surfaces are urged together, said pressure bearing and sliding sleeve assembly and their respective alignment surfaces being relatively radially movable for centering said bearing during assembly of this device, and being relatively radially fixed after said adhesive means bonds together said alignment surfaces.
Claim 8
Dependent Claim
142 words
A clutch disengaging device comprising a sliding sleeve assembly and a self-centering clutch pressure bearing which includes a stationary bearing ring, the improvement wherein said sliding sleeve assembly comprises a first annular part with a first alignment surface thereon facing generally axially, said stationary bearing ring comprises a second annular part with a second alignment surface thereon facing said first alignment surface, holding means for engaging and restraining said first and second annular parts from relative axial movement, and adhesive bonding means secured to at least one of said alignment surfaces and being adhereable to the other when said surfaces are urged together, said pressure bearing and sliding sleeve assembly and their respective alignment surfaces being relatively radially movable for centering said bearing during assembly of this device, and being relatively radially fixed after said adhesive means bonds together said alignment surfaces.
Claim 9
Dependent Claim
22 words
A device according to claim 6 wherein said first and second annular parts comprise first and second flanges respectively, extending radially outward.
Claim 10
Dependent Claim
21 words
