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.
Claims9
A method for the manufacture of a vehicle wheel wherein a cast preform with a wheel body, a radial flange and a coaxial region is formed into a wheel body and a rim having at least one undercut and an outer and inner rim horn, comprising the steps of:
- preshaping the coaxial region into a rim bed with an inside horn, wherein said preshaping is performed with spinning rollers;
- splitting the radial flange into an inner leg and an outer leg;
- preshaping the inner leg into a rim shoulder thereby forming the at least one undercut;
- preshaping the outer leg into an outer rim horn;
- and,
- machining the rim bed, the outer rim horn, the inner rim horn and the rim shoulder to achieve the respective final profiles.
