Automotive wheel construction
Abstract:
A drawn automotive vehicle wheel comprising first and second wheel halves contiguous about a disc plate positioned in between. The wheel halves are generally cup-shaped, each having a center section and an integral rim section and the disc plate is of similar planar configuration as the respective center sections. In the respective center sections and in the disc plate are respectively congruent apertures with integral projections emanating from the rear surface of each center section, defining a central opening and alignment apertures. The wheel halves are placed and secured back to back with the disc plate between, allowing reception into the plate of the lip-like projections, resulting in the spatial correspondence of the apertures among the three wheel elements, and thus, retention of proper elemental alignment under high torque conditions. Another embodiment requires no disc plate as the projections emanate from one center section only, and are received by the corresponding apertures in the second wheel half.
