The invention relates to a wheel disc for vehicle wheels, in particular for passenger cars, manufactured by spinning, having a stretched disc transition surface 20 and a radially outer disc edge, the transition surface 20 being subsequently provided with ventilation holes 30. All ventilation holes 30 are located in the transition surface 20 and are added by stamping or cutting. In order to improve the competitiveness of vehicle wheels made of steel or other suitable materials, in particular suitable for cold forming, compared to cast vehicle wheels made of aluminum, according to the invention the transition surface (20) is provided with a plurality of variations in the material thickness that result from the displacement of the tool during the spinning process and, as viewed in the radial direction, the transition surface (20) is provided with a plurality of variations in the material thickness that result from the displacement of the tool. The transition surface (20) achieves an undulating structure on the tool-facing surface during the spinning process. The surface provided with the wave-shaped structure may in particular form an invisible inner side of the vehicle wheel, but may also form a visible side. In addition, the opposite surface may also be provided with a wave-shaped structure.
本发明涉及通过旋压制造的用于车辆车轮的轮盘,特别地用于客车的轮盘,该轮盘具有拉伸的盘过渡表面20和径向外部盘边缘,该过渡表面20随后设置有通风孔30。所有通风孔30位于过渡表面20中,并且通过冲压或切割来附加。为了改善由钢或其他适合的材料、特别地适合于冷成型的材料、制成的车辆车轮与由铝制成的铸造车辆车轮相比的竞争力,根据本发明,过渡表面(20)设置有在旋压过程中通过工具的移位而产生的材料厚度的多个变化,并且在径向方向上观察,过渡表面(20)在旋压过程中面向工具的表面上实现波形结构。设置有波形结构的表面特别地可以形成车辆车轮的不可见内部侧,但也可以形成可见侧。此外,相反表面也可以设置有波形结构。
