Wheel hub and bearing assembly packaging
A packaging system having an outboard guard and an outboard retainer cap. The outboard guard includes an outboard guard opening having a hole through the planform of the outboard guard, an engagement portion having an annular surface radially surrounding the outboard guard opening, an outboard bearing protector portion having an annular surface radially surrounding the engagement portion of the outboard guard, and an outer rim having an annular surface radially surrounding the outboard bearing protector portion. The outboard retainer cap is configured to be removably affixed to the outboard guard and includes an outboard alignment protrusion having a circular surface, an engagement portion having an annular surface radially surrounding the outboard alignment protrusion, and a retaining flange having an annular surface radially surrounding the engagement portion of the outboard retainer cap.
1. A wheel hub assembly comprising:
a vehicle wheel hub having a wheel hub bore configured to accept a vehicle spindle;
an inboard bearing assembly installed on an inboard side of the vehicle wheel hub and comprising an inboard bearing cone and inboard bearing elements;
an outboard bearing assembly installed on an outboard side of the vehicle wheel hub and comprising an outboard bearing cone and outboard bearing elements; and
outboard packaging comprising an outboard retainer cap removably affixed within an outboard guard by an interference fit between the outboard retainer cap and the outboard guard, the outboard guard being removably affixed to an outboard side of the vehicle wheel hub and retaining the outboard bearing assembly within the vehicle wheel hub, a portion of the outboard retainer cap extending through an opening in the outboard guard and into the outboard side of the wheel hub bore of the vehicle wheel hub, the portion of the outboard retainer cap contacting an inner diameter of the outboard bearing cone to align the outboard bearing assembly within the wheel hub.
2. The wheel hub assembly of claim 1 , in which the outboard retainer cap contacts an outboard end of the outboard bearing cone.
3. The wheel hub assembly of claim 1 , in which the outboard guard contacts the outboard bearing assembly.
4. The wheel hub assembly of claim 1 , in which the outboard guard is removably affixed to the vehicle wheel hub by an interference fit between the outboard guard and the vehicle wheel hub.
5. The wheel hub assembly of claim 1 , further comprising an inboard guard removably affixed to an inboard side of the vehicle wheel hub and retaining the inboard bearing assembly within the vehicle wheel hub, a portion of the inboard guard extending into the inboard side of the wheel hub bore of the vehicle wheel hub, the portion of the inboard guard contacting an inner diameter of the inboard bearing cone to align the inboard bearing assembly within the wheel hub, the inboard guard contacting an inboard end of the inboard bearing cone.
6. The wheel hub assembly of claim 5 , the wheel hub assembly further comprising a wheel hub seal on the inboard side of the vehicle wheel hub, in which the inboard guard does not contact an inboard side of the wheel hub seal.
