A self centering clutch thrust bearing has a damping ring between one bearing ring and the sliding sleeve of a housing. The damping ring has resilient projections positioned to engage recesses in the housing with play, to damp small turning motions, and larger projections positioned to engage other recesses in the housing with play, to damp larger turning forces. The resilient projections are mounted to be operative in damping the forces prior to the larger projections. This invention relates to self centering clutch thrust bearings, and more in particular to the provision of damping means in such bearings.

In a self centering clutch thrust bearing having rotating outer bearing ring means with an annular surface adapted to engage a clutch lever, fixed inner bearing ring means axially extending toward the clutch side of said bearing, a plurality of rolling bodies in a cage between said rotating and fixed bearing rings, a sliding housing having a sliding sleeve, and a surface adapted to axially engage said inner bearing ring means and have limited radial and circumferential movement with respect thereto, and a damping ring of resilient material between said inner bearing ring means and sliding sleeve, said damping ring having resilient fingers extending toward said sleeve, and wherein said inner ring means and sleeve are spaced sufficiently to permit radial play therebetween; the improvement wherein said damping ring, on the side thereof axially extending away from said clutch, has axially directed first projection means and axially directed second projection means, said projection means engaging recesses in said housing with play, said second projection means having less resiliency than said first projection means and being adapted to engage the sides of the respective recesses in said housing after said first projection means have engaged the sides of their respective recesses upon turning movements in said bearing.
