Abstract
A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.
Claims16
An apparatus comprising,
- a unitized wheelend assembly comprising:
- a hub having an inboard side and an outboard side defining a cavity therebetween;
- an oil seal having an inboard side and an outboard side proximal the inboard side of the unitized wheelend assembly;
- an inboard bearing assembly having an inboard side proximal the outboard side of the oil seal and an outboard side;
- a spacer having an inboard side proximal the outboard side of the inboard bearing assembly and an outboard side;
- an outboard bearing assembly having an inboard side proximal the outboard side of the spacer and an outboard side;
- a spindle nut assembly, the spindle nut assembly having an inboard side proximal the outboard side of the outboard bearing and an outboard side, the spindle nut assembly having a shape;
- and
- a retainer having an inboard side, an outboard side, and a body extending therebetween, the inboard side of the retainer having an inboard edge, the retainer having a bore with a shape to cooperatively engage the shape of the spindle nut assembly and an outboard side, the retainer having at least one protruding surface to receive a fastener such that the retainer may be releasably coupled to the outboard side of the hub.
