METHOD FOR PRODUCING A FULL FACE FABRICATED VEHICLE WHEEL

摘要

A full-face disc (32) is subjected to a combination of stamping and flow-spinning operations in the manufacture of a full-face wheel (100). The method employs the following steps: a) providing a circular rim (90) with a well (96), a tire bead seat retaining flange (92) and a tire bead seat (94) at the rim's inboard end and another bead seat (98) at the rim's outboard end; b) providing a circular disc blank (30) having an inner annular portion defining a wheel mounting surface (34); c) performing a series of stamping operations on the disc (32) to form an intermediate annular portion with a predetermined contour and an outer annular portion forming the wheel's outboard tire bead seat retaining flange (70), and performing a flow-spinning operation to taper a portion of the disc (32); d) positioning the disc's outboard retaining flange (70) adjacent the rim's outboard bead seat (98) and securing them together.
