ABSTRACT:
A wheel consists of a cast wheel spider which comprises several hollow spokes and which is connected with a rim ring by way of a weld, particularly a friction weld. In the area of the outer circumference, the hollow spokes have internal core openings for a sand core, and the openings are directed toward the rim ring. The wheel spider has bolt bores which are arranged concentrically with resect to a centric wheel opening and which are provided with bore sleeves which are cast approximately in the center inside the hollow spoke and have radially extending reinforcing ribs 11. In the area of the core openings, the wheel spider has at least one reinforcing element between opposite walls of each hollow spoke. The reinforcing element preferably consists of two cylindrically cast pins respectively which extend in parallel to the wheel axis and are arranged at a distance from one another and are situated on both sides of a transverse wheel plane defined by the reinforcing rib.
