Abstract:
A method for producing a one-part vehicle wheel, wherein the one-part vehicle wheel includes a hub and a rim, and wherein the method comprises the steps of:splitting a circumferential area of a pre-form to form first and second legs; flow-forming an intermediate configuration for the one-part vehicle wheel so as to shape the first leg into a rim base area, the rim base area substantially having a wall thickness which is as thick as the rim of the one-part vehicle wheel, once finished, and the second leg forming a radial flange; further splitting so that the radial flange, formed from the second leg, is split into an outer leg and an inner leg, the inner leg extending in a direction towards the rim base area; shaping a rim bead from the outer leg; shaping a roughly axially directed rim shoulder from the inner leg; and forming an undercut between the rim base area and the rim shoulder.
