Abstract
A motor vehicle wheel having hollow spokes and made of a light metal is produced in a casting process. In the hollow space, the wheel spokes have a dead core consisting of a metallic material in the form of a metal foam or of a closed shell-shaped element, which dead core remains in the hollow space after casting.
Claims3
A motor vehicle wheel having hollow spokes made of a light metal and producible in a casting operation, each of said spokes having a dead core made of a metallic material in a hollow space, said dead core forming a closed space in the spoke,
- wherein the dead core is arranged to be positioned centrically with respect to the wheel and extends from a wheel center into the hollow space of each wheel spoke and into an annulus at a radial end of each wheel spoke, and
- wherein the dead core projects out of the wheel center and is mechanically machined to form a continuous bore for receiving a central bush.
