ABSTRACT:
Mounted in a suspension upright for land vehicles, there is provided an arrangement comprising a constant velocity joint, a hub and two wheel bearings with provision for preload adjustment, wherein the CV joint's outer race proper is the inboard wheel bearing's inner race. The bearing raceway formed on the exterior surface of the CV joint's outer race proper is located so as to be in the general area occupied by the driven plane in line with the CV joint's flexural center, providing full end support to the CV joint itself, and concurrently bring about increased axial spacing between the inboard and outboard bearings. Having the CV joint's outer race proper thus integrated to the inboard wheel bearing, a robust hub assembly is provided, wherein the CV joint's flexural center can be placed more closely to the wheel center plane than is normally possible, making negative scrub radius with low kingpin inclination easily achievable.
