A vehicle wheel e.g. for passenger cars, having a disc part connected to a rim part, the disc part, integrally formed form a sheet metal blank, has a central part with bolt holes for wheel bolts and a central hole for a vehicle hub, and a plurality of radially extending spoke arrangements for transmitting forces between the vehicle hub and the rim part. Each spoke arrangement is provided with a central web, merging on both sides into a radially extending side web, being bent outwards from the surface of the central web, and an edge web, bent back again relative to the side web, wherein the radially outer ends of the webs merge into a disc rim, being aligned parallel to the wheel axis, connecting all spoke arrangements to one another and delimiting ventilation holes. In order to provide, without structural drawbacks, steel vehicle wheels with an unequal number of bolt holes and spoke arrangements, an inner annular bead and an outer annular bead are formed in the central part, which beads are concentric with one another and with the disc rim, and a raised annular strip provided with the bolt holes is formed between the beads.
A vehicle wheel having a rim part for holding a tyre and having a disc part, which is connected to the rim part, which is formed from an integral sheet metal blank by forming and cutting or punching and having a central part, having bolt holes for wheel bolts and a central hole for a vehicle hub, and which disc part is having a plurality of radially extending spoke arrangements, formed by sheet metal forming, for transmitting forces between the vehicle hub and the rim part, wherein each spoke arrangement is provided with a radially extending central web, which merges on both sides into a radially extending side web, bent outwards from a surface of the central web, and an edge web, bent back again relative to the side web, wherein radially outer ends of the central webs and of the side webs merge into an encircling annular disc rim, which is aligned precisely parallel to a wheel axis or substantially parallel to the wheel axis and connects all the spoke arrangements to one another and is formed integrally from the sheet metal, forms a connecting part for a connection between the rim part and the disc part and, in each case together with the edge webs of adjacent spoke arrangements, delimits ventilation holes which extend over a region between the edge webs and the disc rim, wherein the number of spoke arrangements and the number of bolt holes is unequal, and a quotient of the number of spoke arrangements to bolt holes does not give a natural number, and wherein an inner annular bead and an outer annular bead are formed in the central part, which inner and outer annular beads are concentric with one another and with the disc rim and between which a raised annular strip provided with the bolt holes is formed.
