Abstract
A wheel hub assembly for an automotive vehicle has a spindle with a flange by which a wheel is mounted, the spindle being supported by a support member and being rotated through a universal joint. Axially spaced inboard and outboard bearing members are positioned between the spindle and the support member. The spindle has a tapered raceway forming a cone of the outboard bearing member, the raceway lying inboard of the flange. The outboard bearing member cone raceway has no thrust rib at its large, outboard end, and a large radius is provided between the outboard end of the raceway and the flange. An outboard bearing member cup has a raceway tapered complementarily to the cone raceway and a thrust rib at its outboard end. Preferably, the inboard bearing member has a cone with no thrust rib, and a cup with a thrust rib.
