Definitions

  • the present invention overcomes this drawback by creating a method of manufacturing so-called “style” wheels by creeping the metal in cavities of a mold adapted to the desired shape in order to obtain a wheel having the desired shape.
  • the invention also extends to the wheel obtained by this process.
  • the method is characterized by the fact that after having roughened the wheel by stamping with a press from a flat disc, the flange of the wheel is finished by creeping of the metal in the cavities. 'A suitable mold then the rim on which the tire is mounted is obtained by splitting, stamping, magnetoforming.
  • Fig. 1 is a plan view of the disc from which the so-called “style” wheel will be produced.
  • Fig. 2 is a side elevation, partly in section, of the wheel during manufacture.
  • Fig. 3 is a partial plan of the style wheel, obtained by the method of the invention.
  • the periphery of the wheel forms a crown 3 which is then, for example, cut into two parts 3a, 3b by splitting and, when these two half-discs forming between them a circular V are obtained, they are subjected to processes stamping and magnetoforming, for example, to finally obtain the rim on which the tire can be mounted.
  • stamping with the press then by creep, the actual rim 2 is obtained having extra thicknesses 10, 11, 12 as well as connecting zones 13, 14 giving a wheel called "style".
  • the use of the creep method makes it possible, by using a light alloy of good mechanical strength, to obtain a wheel of very low weight which can be, for example, one third of the weight of a wheel obtained by prior methods.
