Abstract:
A method of manufacturing a full face vehicle wheel having a high durability performance, in which the back surface of a wheel disk is provided in advance with an annular joining groove. A peripheral joining end of a wheel rim is provided in advance with an inside slope end surface. The peripheral joining end is seated and positioned on the bottom surface of the annular joining groove. A welding heat confining annular region is produced between the inside groove wall of the annular joining groove and the inside slope end surface. The annular joining groove and the peripheral joining end are joined by welding.
Abstract:
A method of forming a wheel disc starts with a flat blank. A plurality of windows are formed in the wheel disc, wherein each window has a respective outer edge proximate with a continuous outer band around a periphery of the wheel disc. The windows define a plurality of spokes between adjacent windows, and the angular size of each of the windows along the outer band is preferably greater than the angular size of each of the spokes. The outer band is partially closed toward a cylindrical shape by engaging a cam die against at least a portion of the outer band. The outer band is substantially fully closed into a cylindrical shape by axially wiping the outer band using a cylindrical die. The intermediate camming operation achieves the desired final shape after wiping without introducing stresses that would weaken or distort the wheel disc.
Abstract:
A method of processing a vehicle wheel/rim preform with a first rotational axis and having a centersection/spider and an annular wall extending around the centersection/spider and first rotational axis and having an annular surface defining axially spaced, annular inboard and outboard bead seats. The method includes the steps of: providing a workpiece support having a chuck assembly that is rotatable around a second axis and at least one rim wall support assembly; engaging the chuck assembly with the centersection/spider to maintain the vehicle wheel/rim preform in a processing position on the chuck assembly wherein the first rotational axis on the vehicle wheel/rim preform is substantially coincident with the second axis; engaging the at least one rim wall support assembly with the annular wall to exert a force with a radial component upon the annular wall to thereby stabilize the wheel/rim preform; and processing the vehicle wheel/rim preform at the annular surface fully axially between the inboard and outboard bead seats with the vehicle wheel/rim preform maintained in the processing position and rotated by the chuck assembly around the second axis.

Abstract:
A two-piece tire rim is prepared from a molded, one-piece wheel casting which is generally cup-shaped in configuration. The casting, which is open at one end and closed at its opposite end, has an inner annular recess formed coaxially in the inner surface of its closed end, and has formed coaxially in its outer peripheral surface an external annular recess radially spaced from, and in axial registry with an internal annular recess. The casting is separated into two separate sections by cutting through the casting in a circular path extending from the external annular recess to the internal annular recess, thereby producing a generally annular shaped inner rim section, and a generally disc-shaped outer rim section. The two rim sections are then machined to final form, and are secured together to form the desired two-piece tire rim.

Abstract:
A full face wheel assembly comprises a full face disc and a rim. The disc is preferably cast from aluminum whereas the rim is rolled from aluminum strip stock. The full face disc comprises an outboard bead seat flange, an outboard bead seat and an outboard well side wall. The disc may also include lightener pockets or a continuous re-entrant channel adjacent the outboard bead seat. The rim comprises an inboard bead seat flange, an inboard bead seat, an inboard leg, and a deep well. The disc and rim are welded together in the deep well or bead seat regions by gas metal arc welding, electron beam welding or other suitable welding technique.
