Abstract: A vehicle wheel assembly includes a hub adaptor that eliminates the need for a separate hub cap and gasket by providing wheel rim, wheel hub, and brake component attachment interfaces, as well as a lubrication chamber that can be visually inspected to monitor lubrication levels. The hub adaptor comprises a single piece body having an outwardly extending mounting flange with a first plurality of apertures that define a wheel rim attachment interface. The hub adaptor also includes an inner recessed area with a second plurality of apertures that define both the wheel hub and brake component attachment interfaces. The hub adaptor also includes an inner circumferential surface that provides a piloting and sealing interface between the hub adaptor and the wheel hub.

Abstract: A brake drum includes a plurality of ribs formed on an outer surface with each rib extending about the circumference of the drum. Recesses are formed between the ribs that also extend about the circumference of the drum. Wedges are secured between the ribs, within the recesses, to direct air flow away from the drum.
