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.
