Abstract
Abstract A self-centering clutch release bearing comprises a drive element which acts on the release device of a clutch, connected to an actuating element which co-operates with a displacement control means. The connection between the two elements is a self-centering frictional connection controlled by a Belleville washer which bears with its inner or outer periphery against one of the elements. The washer is connected to the other of the elements by fastening claws which extend around its other periphery.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
144 words
A clutch release bearing of the kind comprising an actuating element having means for cooperation with clutch actuating means, and a drive element having a surface portion for cooperation with a clutch release member, said clutch release bearing having an axis, a self-centering connecting means of one-piece resilient construction connecting said actuating element and drive element together and permitting relative movements in all directions in a plane perpendicular to the axis of said clutch release bearing, and said self-centering connecting means comprising an axially acting resilient clamping Belleville washer bearing on one periphery thereof against one of said elements, and integral fastening claws disposed around and projecting from said other periphery of said Belleville washer in spaced relation, said fastening claws being engaged with said other element and acting in tension thereon while said Belleville washer axially resiliently urges said elements towards each other.
Claim 2
Dependent Claim
144 words
A clutch release bearing of the kind comprising an actuating element having means for cooperation with clutch actuating means, and a drive element having a surface portion for cooperation with a clutch release member, said clutch release bearing having an axis, a self-centering connecting means of one-piece resilient construction connecting said actuating element and drive element together and permitting relative movements in all directions in a plane perpendicular to the axis of said clutch release bearing, and said self-centering connecting means comprising an axially acting resilient clamping Belleville washer bearing on one periphery thereof against one of said elements, and integral fastening claws disposed around and projecting from said other periphery of said Belleville washer in spaced relation, said fastening claws being engaged with said other element and acting in tension thereon while said Belleville washer axially resiliently urges said elements towards each other.
