POLYGONAL HUB FOR FULLY FLOATING REAR DRIVE AXLE OF A VEHICLE

摘要

A polygonal hub for fully floating rear drive axle of a vehicle used in the break drum and wheel assembly comprising a hub (4) which rotates on the supporting member (10) of axle drive shaft assembled with inner bearing (5) and outer bearing (7) in the housing therein to enable to rotate freely about an axis and are fixed in position with the member (10); the complete wheel end assembly is then packed with lock nut (12). The hub having a flange (15) carries wheel bolt (2) which provides seating for brake drum (1) and wheel rim and tightened with the use of wheel nut (3). The hub (4) is formed by casting. An embodiment provides a hexagonal shape to the central portion instead of circular shape of the hub.
