ABSTRACT:
A vehicle wheel and adapter allowing the wheel to be fastened by means of a single knock-off type hub nut to a disk brake hub or brake drum of a vehicle utilizing wheels of the type that are attached by a plurality of lug bolts or lug nuts includes a circular adapter plate provided with mounting holes to permit the adapter to be attached using existing lug bolts or lug nuts. The adapter plate has an axially forwardly protruding central coaxial tube section externally threaded on an outer axial portion thereof, and a plurality of longitudinally disposed, arcuate transverse section splines protruding radially outwards from an intermediate longitudinal portion of the tube section. A wheel hub having a tubular front section and a larger diameter, dish-shaped rear section has an internally splined intermediate longitudinal portion provided with grooves adapted to longitudinally slidably receive the splines. The tubular front section of the wheel hub has an inwardly and rearwardly tapered, frusto-conically shaped entrance opening. A slotted hub nut having a slotted, frusto-conically shaped outer wall is distorted radially outwards when tightened on the threaded tube section of the adapter, thereby exerting radially outwardly directed centering forces on the wheel hub. In the preferred embodiment, both the externally splined section of the adapter and the internally splined section of the wheel hub have in transverse section an approximately sinusoidal shape, to provide stress relief.
