Abstract

A motor vehicle wheel and wheel support assembly for holding a wheel onto a motor vehicle which wheel may be quickly removed by unscrewing a single central knock-off nut. The assembly has a hub adapter which is bolted to the brake drum or brake disk using the conventional lug bolts and lug nuts. The hub adapter has an angled outer flange in the shape of a decagon or other multi-sided polygon. The outer surface has a slight angle such as five (5) degrees with respect to the central axis. The wheel has a mating shape and the hub adapter has a threaded extension which accepts the knock-off nut. When the wheel is placed so that its angled decagon mates with the angled decagon of the hub adapter, it may be securely held to the hub adapter by tightening a knock-off nut against the outer surface of the wheel. Thus, the wheel may be removed from the motor vehicle by simply removing the knock-off nut.

Dependent claims

A motor vehicle wire wheel and wheel support assembly for holding a wire wheel onto a motor vehicle which wire wheel may be removed by removing a knock off nut, said wire wheel and wheel support assembly comprising:

a hub adapter comprising:
a flange having a central axis and a brake member contact face, an outer peripheral edge and a wheel directed face, said flange having a plurality of lug bolt openings parallel to said central axis and passing from said brake member contact face to said wheel directed face and the outer peripheral edge having an angled generally regular polygonal configuration comprising a decagon, the angle of said angled generally regular polygonal configuration comprising a decagon being between one and thirty degrees with respect to said central axis;
a generally cylindrical knock-off nut accepting portion extending co-axially from said wheel directed face of said flange, said nut accepting portion having an external thread at an outer end thereof;
a wire wheel having a hub and a rim and a plurality of spokes, said hub including a flange accepting surface shaped to contact the angled generally regular polygonal configuration comprising a decagon of said flange and said flange accepting surface including openings which hold an inner end of a plurality of said plurality of spokes and said hub including a central ring having a knock off nut contacting surface near an exterior end thereof;
and
a knock off nut having an internally threaded nut portion shaped to tighten onto the external thread of said generally cylindrical knock-off nut accepting portion of said hub adapter and to tighten against said wire wheel whereby said wire wheel may be securely and axially held to said hub adapter by placing the flange accepting surface of said wire wheel against the outer peripheral edge of said hub adapter and tightening said knock off nut against said wheel hub.
