Abstract: The invention relates to a vehicle hybrid wheel comprising a formed steel rim ring and a wheel disk, manufactured as a light-alloy casting having a concentrically formed disk edge, on which the rim ring bears at least partially at multiple, spaced contact points for rotationally fixed connection to the wheel disk. In order to ensure an adequate force flux between the rim ring and the wheel disk, the wheel disk is provided with a circumferentially formed depression, in which a circumferential edge of the rim ring, angled radially outwards in relation to a bead seat section formed on the rim ring, engages by positive interlock and/or force closure.

Abstract: A method of forming a casting includes providing a preform to a mold cavity. The preform is formed from one of a first metal and a second metal and defines an interface surface. A molten portion of the other of the first metal and the second metal is cast into the mold such that the molten portion proximately contacts the interface surface of the preform. An interface layer at the interface surface, a first portion defined by the mold cavity and the interface layer, and a second portion defined by the interface layer, are formed during casting. The interface layer may define a metallurgical bond between the first portion and the second portion. In the non-limiting example provided herein, the first portion is substantially comprised of aluminum and the second portion is substantially comprised of magnesium. In a non-limiting example, the casting may be configured as a vehicle wheel.

Abstract: An inner peripheral end portion of an annular back peripheral portion forming a front flange portion, an opening end portion of a front bead seat portion and a back surface portion of a wheel disc are joined to each other by a first welded portion and a second welded portion. Accordingly, it is possible to prevent the front flange portion from being repeatedly elastically deformed by loads generated while the automobile is running. In addition, it is possible to mitigate a stress concentration generated on the front flange portion and the first welded portion and the second welded portion. Thus, an automobile wheel can exhibit high durability.

Abstract: A two-piece tire rim is prepared from a molded, one-piece wheel casting which is generally cup-shaped in configuration. The casting, which is open at one end and closed at its opposite end, has an inner annular recess formed coaxially in the inner surface of its closed end, and has formed coaxially in its outer peripheral surface an external annular recess radially spaced from, and in axial registry with an internal annular recess. The casting is separated into two separate sections by cutting through the casting in a circular path extending from the external annular recess to the internal annular recess, thereby producing a generally annular shaped inner rim section, and a generally disc-shaped outer rim section. The two rim sections are then machined to final form, and are secured together to form the desired two-piece tire rim.
