Beschreibung
Zusammenfassung:	The invention relates to a wheel disc for vehicle wheels manufactured by flow forming, in particular for passenger cars, which has a stretched disc transition surface 20 subsequently provided with ventilation holes 30 and a radial outer disc edge. All ventilation holes 30 are located in the transition surface 20 and are attached by punching or cutting. In order to improve the competitiveness of vehicle wheels made of steel or other materials suitable in particular for cold forming compared to cast vehicle wheels made of aluminium, according to the invention, the transition surface (20) is provided with several changes in material thickness generated during flow forming by displacement of the tool and, viewed in the radial direction, effecting a wave structure on the surface facing the tool during flow forming. The surface provided with the wave structure can in particular form the non-visible inner side of a vehicle wheel, but can also form the visible side. In addition, the opposite surface can also be provided with a wave structure.
