ABSTRACT:
An improved differential mechanism of the holdout ring type, characterized by the provision of a pair of annular thrust blocks engaged by sets of Belleville disc-spring washers which bias a pair of side gears axially outwardly apart against a pair of annular thrust washers, respectively, non-rotatably supported by the differential housing. By loading the side gears in the axial direction, the side gear radial freedom of movement is restricted, whereby the differential chatter and noise level during operation are significantly reduced.
