Oval spline-drive wheel and adapter

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