Abstract
In a noise reducing disengagement device for motor vehicle clutches having rolling elements and adapted to be radially displaceable with respect to a sliding sleeve, the bearing includes an apertured fixed race having a radially directed flange on a plate fixedly mounted with respect to the sleeve. The fixed race has a damping ring coupled thereto and contacting the flange on the side toward the rolling elements, and at least three damping members distributed on the circumference of the plate. The plate includes a plurality of recesses, the damping members passing through the apertures in the fixed race and entering the recesses in the plate.

In a noise reducing clutch disengagement device for clutches, operable with a pressure plate and including a clutch bearing having rolling elements and adapted to be radially displaceable with respect to a sliding sleeve means, said bearing a fixed race having a radially directed flange abutting said pressure plate fixedly mounted with respect to said sleeve means, the improvement wherein said flange includes a plurality of circumferentially spaced apertures extending axially therethrough, said fixed race having a damping ring coupled thereto and contacting said flange on a first side thereof facing toward the rolling elements, a plurality of damping members distributed circumferentially on said damping ring, said pressure plate including a plurality of recesses, said damping members passing through said apertures in said flange and entering said recesses in said pressure plate.
In a noise reducing clutch disengagement device for motor vehicle clutches operable with a pressure plate and including, a clutch bearing having rolling elements and adapted to be radially displaceable with respect to a sliding sleeve means, said bearing including a fixed race having a radially directed flange abutting said pressure plate fixedly mounted with respect to said sleeve means, said flange comprising a plurality of circumferentially spaced apertures extending axially therethrough, said fixed race having a damping ring coupled thereto and contacting said flange on a first side thereof facing toward the rolling elements, said damping ring comprising at least three damping members distributed circumferentially thereon, said pressure plate including a plurality of recesses, said damping members passing through said apertures in said fixed race and entering said recesses in said pressure plate.
In a clutch disengagement device operable with a pressure plate and including a clutch bearing which has rolling elements and is adapted to be radially displaceable with respect to a sliding sleeve, the improvement wherein (a) said bearing comprises a fixed race having a radially directed flange abutting said pressure plate, the pressure plate being fixedly mounted with respect to said sliding sleeve, said flange having a first side thereof facing toward said rolling elements, said flange including a plurality of circumferentially spaced apertures extending axially therethrough, (b) said device further comprises a damping ring secured to said flange on said first side thereof, with a plurality of damping members distributed circumferentially on said damping ring and extending axially therefrom in the direction away from said rolling elements and toward said pressure plate, and (c) said pressure plate comprises means for engaging each of said damping members, said damping members on the damping ring, said apertures in said flange, and said means for engaging said damping members all having generally the same circumferential spacing pattern, with said damping members extending axially through said engaging said apertures and further extending to and engaging said engaging means on said pressure plate.
