Abstract
Abstract A clutch disengagement device having an antifriction bearing connected for radial movement on a sliding sleeve by a centering ring. The centering ring, which is fastened to the nonrotating bearing race, is fastened to the sliding sleeve by at least one clamp which surrounds a radial flange of the sliding sleeve, or of the centering ring, with radial play.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
62 words
A clutch disengager comprising an antifriction bearing having a rotating race and a nonrotating race, a sleeve having a radially extending flange, centering ring means on said nonrotating race, and clamping means mounted to clamp said centering ring means and said flange in the axial direction of said bearing while permitting radial movement of said nonrotating race with respect to said sleeve.
Claim 2
Dependent Claim
62 words
A clutch disengager comprising an antifriction bearing having a rotating race and a nonrotating race, a sleeve having a radially extending flange, centering ring means on said nonrotating race, and clamping means mounted to clamp said centering ring means and said flange in the axial direction of said bearing while permitting radial movement of said nonrotating race with respect to said sleeve.
Claim 3
Dependent Claim
27 words
The clutch disengager of claim 1, wherein said clamping means is mounted to clamp said centering ring means and flange in both axial directions of said bearing.
Claim 4
Dependent Claim
18 words
The clutch disengager of claim 1, wherein said clamping means is integral with said sliding sleeve radial flange.
Claim 5
Dependent Claim
17 words
The clutch disengager of claim 1, wherein said clamping means is integral with said centering ring means.
Claim 6
Dependent Claim
15 words
The clutch disengager of claim 1, wherein said centering ring means surrounds said nonrotating race.
Claim 7
Dependent Claim
21 words
The clutch disengager of claim 1, wherein said nonrotating race is placed on an axial shoulder of said centering ring means.
Claim 8
Dependent Claim
25 words
The clutch disengager of claim 1, wherein said clamping means engages a recess formed in said radial flange of said sliding sleeve with radial play.
Claim 9
Dependent Claim
34 words
The clutch disengager of claim 1, wherein said clamping means includes a radial surface for contact with a disengagement fork, said radial surface including a pressure ring which is hardened for contacting said fork.
Claim 10
Dependent Claim
24 words
The clutch disengager of claim 1, wherein a filling ring is arranged between an outer race of said antifriction bearing and said sliding sleeve.
Claim 11
Dependent Claim
117 words
A clutch disengager comprising a sliding sleeve, an antifriction bearing mounted for radial movement on said sliding sleeve, said antifriction bearing having a rotating and a nonrotating race with roller elements encaged therebetween, a centering ring fastened to said nonrotating race, said sliding sleeve including a radial flange extending outwardly therefrom, and clamping means for clamping said centering ring and said radial flange together in both axial directions of said bearing while allowing radial play between said centering ring and radial flange for adjusting the radial position of said bearing on said sleeve in accordance with a radial centering force, said bearing including a curved face and means contacting said curved face for applying said radial force.
Claim 12
Dependent Claim
