Abstract
In a clutch release bearing assembly for a motor vehicle, the outer ring of a clutch thrust bearing has a flange engaging a radially extending flange of a housing part affixed to a sliding sleeve. This engagement permits play. An elastic ring is held fixed with respect to the outer bearing ring, and has projections extending axially from its internal circumference to engage circular surfaces of recesses of the housing. The circular surfaces of the recesses are joined by straight sections on the housing, whereby the tendency of the sliding sleeve to rotate with respect to the bearing ring effects the radial bending of the tongues, to damp such movement.
Claims11
In a clutch release bearing assembly, in which a clutch thrust bearing is mounted to be radially displaceable with respect to sliding sleeve means and has a fixed bearing ring and a rotatable bearing ring, housing means coupled to the sliding sleeve has a radially directed flange that engages said fixed bearing ring of said clutch thrust bearing, said fixed bearing ring having a bore, and a ring of elastic material is positioned in the bore or on the surface of the fixed bearing ring, the ring of elastic material constituting means for damping the relative movement of the clutch thrust bearing with respect to the sliding sleeve;
- the improvement wherein said housing means has a bore with axially directed open recesses facing said clutch thrust bearing, said damping ring having resilient tongues extending substantially axially from its inner circumference, said resilient tongues engaging said recesses of said housing means, the outer radial surface of each said recess having a circular shape, and being joined at its circumferential ends to a flat surface extending between adjacent recesses.
In a clutch release bearing assembly wherein the fixed bearing ring of a clutch thrust bearing has a flange, flange means coupled to a sliding sleeve, said flange axially engaging with play said flange means, and a ring of elastic material is mounted to damp relative movement between the sliding sleeve and the fixed bearing ring;
- the improvement wherein said flange means has recesses on the end thereof facing said fixed ring, said recesses having radial surfaces that are circular, the circumferential end of the circular surfaces of each recess joining a non-circular surface that joins the next adjacent recess, and said elastic ring is held with respect to said fixed ring and has tongue means extending axially to abut said circular surfaces.
