Abstract
A two-piece modular automotive wheel includes a rear section having a relatively thick center portion and a thinner rim portion. The rear section is produced by a spin forging process to achieve the desired thickness at various locations. A registration surface is machined in the center portion. A front rim section is secured to the rear section at the registration surface. A locking ring, which may also be spun forged, may be secured to the front rim section to lock the bead of the tire.
Claims4
A modular vehicle wheel comprising:
- a one piece first section having a center portion having a central opening therethrough and a first rim extending from the end of the center portion and having a cross-sectional thickness which is less than that of the center portion, said center portion including a peripheral circular machined registration surface spaced from the central opening on the side thereof facing away from the rim, said registration surface defining a circular ridge;
- and
- a second section defining a second rim and having a central opening approximately the same diameter as the diameter of the ridge, wherein the second section is secured to the first section at the registration surface and the ridge centers the second section with respect to the first section and wherein the resulting wheel has first and second rims and a single layer center section extending from the registration surface to the central opening.
