Abstract:
A light-metal strip wheel, in particular for motor vehicles, which includes a wheel disk and a rim. The wheel disk comprises two wheel-disk parts each having a ventilation hole. The ventilation holes have necks that when pressed into one another, secure together the two wheel-disk parts with the two parts separated from one another in the region surrounding the ventilation holes, while coming to rest on one another in a hub region. The space between the two wheel-disk parts in the region surrounding the ventilation holes increases the stiffness of the strip wheel so that the wheel is suitable for accommodating large loads.
Abstract:
A vehicle wheel including a wheel rim having a central axis and a plurality of generally parallel wheel discs extending across the wheel rim. The wheel discs are spaced axially apart and are generally perpendicular to the central axis. The wheel discs are permanently secured to the wheel rim.
Abstract:
An automotive wheel and a method for manufacturing, in which a center hub is formed using drawing and stamping methods, is disclosed. A mounting foot is spin forged onto the edge portion of the formed center hub, and the center hub is then polished and mounted into a separately formed cylindrical rim. The resulting automotive wheel has the look of a machined billet-type automotive wheel but with a substantial reduction in wasted material and corresponding cost.
Abstract:
An improved wheel disc and disc and and rim wheel assembly, and method and press apparatus for manufacturing the same. The wheel disc is adapted for telescopic press fit precision mounting into a mating wheel rim to form the wheel assembly. A flat disc blank is progressively die formed into a disc preform having a cross-sectional contour proximating that of the finished disc. The disc preform is then placed in a segmental expand punch and die tooling of the press apparatus which operates to apply radial expansion pressure to substantially the entire inner circumference of the peripheral flange portion of the disc preform to thereby permanently deform the same into a finished flange portion on the disc having precision finished predetermined dimensions. A center pilot opening is finish formed in the disc preform in the progressive die forming operation, and then subsequently utilized to locate the disc relative to radial expansion die forming segments in press tooling to thereby ensure concentricity of the finished flange portion upon completion of the permanent radial expansion cold working operation thereon. The apparatus includes an expansion die set-up adjustment mechanism and set-up position sensors to facilitate both initial and running changes in the segmental expansion die set-up exteriorly of the tooling.
Abstract:
A vehicle wheel having an annular clearance groove formed in an inboard surface of a center hub. A plurality of stud holes extend through the hub to the clearance groove. The stud holes receive wheel studs when the wheel is attached to a vehicle. The clearance groove receives any tinnerman nuts which are attached to the wheel studs.
Abstract:
An automotive passenger vehicle, full-face styled wheel construction having a sheet metal disc with an outer peripheral portion formed to provide an outboard tire bead retaining flange. The rim includes an inboard tire bead retaining flange, an inboard tire bead seat portion, a drop-center well portion and an outboard bead seat portion. The outboard edge of the rim has a radially in-turned flange portion extending circumferentially continuously around the rim edge with a radially extending abutment surface at the outboard extremity thereof. The disc outboard flange also has a radially extending rim mating surface disposed in abutment with the rim edge abutment surface. The rim edge flange has a radially inwardly sloping surface extending between the rim outboard bead seat and rim edge abutment surface which defines with the disc outboard flange a trench disposed radially inwardly of the rim outboard bead seat. The rim and disc parts are permanently joined by a circumferentially continuous weld formed in the trench. The disc has an annular array of vent holes with axially inboard offset marginal portions, the radially outermost portions thereof providing a series of circumferentially spaced surfaces collectively defining a disc ledge concentric with the wheel axis. The outboard rim edge flange has a radially inwardly facing cylindrical surface contacting said disc ledge in axially telescoped relationship therewith to thereby locate the rim on the disc and to help support the rim against radially inwardly directed service loading imposed on the rim.
Abstract:
A wheel for heavy vehicles has a rim formed with a well base and a conical bead seat on either side of the well base. A disc is assembled with the rim in such a manner that a reference plane and a reference bore physically formed on the rim are respectively parallel to and coaxial with the middle circle of the rim--defined as the intersection of the rim and the plane of intersection of the conical surfaces of the bead seats.
Abstract:
AN AUTOMOTIVE PASSENGER VEHICLE WHEEL COMPRISING A CAST ALUMINUM WHEEL BODY AND A ROLLED OR STAMPED SHEET STEEL RIM RIGIDLY INTERCONNECTED BY A STEEL RING INSERT CAST INTO THE ALUMINUM BODY AND A CONTINUOUS WELDED JOINT BETWEEN THE STEEL INSERT AND THE RIM, THE WELDED JOINT PREFERABLY BEING FORMED BY A FRICTION INERTIAL WELDING PROCESSS WHEREIN ONE EDGE OF THE RIM IS ROTATED AGAINST THE RING INSERT.
