Abstract
Abstract A vehicle wheel hub which is driven through a constant velocity universal joint has a bearing assembly mounted on the wheel support of the vehicle. The bearing assembly has an inner race mounted on the wheel hub and an outer race mounted on the wheel support. One end of the wheel hub is non-rotatably and detachably connected to the inner joint member of the universal joint and the other end of the wheel hub has a flange to which a wheel can be attached. A flexible boot encloses the universal joint and extends over the bending range of the outer and inner joint members. The boot can be mounted so as to be rotatable or stationary.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
In a bearing assembly for a wheel hub, the combination of a constant velocity universal joint mounted on a wheel support of a vehicle and having rotatable outer and inner joint members, a wheel hub, bearing means journaling said wheel hub within the wheel support and comprising an inner bearing race mounted on said wheel hub and an outer bearing race on the wheel support, said wheel hub having one end non-rotatably but detachably connected to said inner joint member and the other end of said hub having a flange to which a wheel can be attached, and a flexible boot having one end mounted upon said rotatable outer joint member and another end mounted upon one of said wheel support and said wheel hub at said wheel support to enclose said universal joint and extend over the bending range of the outer joint member and the inner joint member such that a seal is defined between rotatable and non-rotatable elements.
Claim 2
Dependent Claim
