Abstract: The invention relates to a method for the manufacture of a vehicle wheel with a wheel body and a rim having at least one undercut. In order to provide a simple, inexpensive method for the manufacture of a weight-reduced vehicle wheel, according to the invention the construction of an undercut in the rim area is integrated into the manufacture thereof by a spinning process. A cast preform having a clearly defined construction, is fixed in a spinning machine where initial preshaping takes place, a rim bed with an inside rim horn is formed and then by splitting and forming a rectangular flange cast radially onto the wheel body, the undercut and an outside rim horn are constructed. Following a heat treatment, machining is carried out for the final rim construction.

Abstract: The invention relates to a method for the manufacture of a rotationally symmetrical part, particularly a vehicle wheel. The starting material is constituted by a circular blank preform, which has a substantially radial base and a connecting, axial shoulder. The shoulder is firstly rolled out by spinning rollers axially on either side of the base to a first web and a second web. At least one of the two webs is spun against a spinning chuck. Subsequently the outer contour of the webs is finally shaped and calibrated in the outer regions.

Abstract: A method of manufacture of a rotationally symmetrical part, particularly a vehicle wheel. In this method, the outer circumferential area of a circular blank is upset for forming a material accumulation or gathering and this preferably takes place asymmetrically. Subsequently, the outer circumferential area of the circular blank is radially split using a splitting roll, which forms two legs. The two legs are subsequently given the desired shape by the utilization of spinning rolls.
