ABSTRACT:
A wheel manufactured from an elongated section of sheet steel is disclosed together with a method for its manufacture. Five rim retaining flanges are formed in the sheet steel. A rim retaining lip is formed along one edge of each of these five flanges. A reinforcing rib is formed adjacent each side of each rim retaining flange, making a total of ten reinforcing ribs. The sheet steel, formed with flanges and ribs, is coiled into a single closed loop. Ten circumferentially spaced radial vanes are formed in the loop. The five rim retaining flanges interconnect pairs of adjacent vanes at the outer diameter of the resulting wheel. At the inner diameter of the resulting wheel, five hub attachment flanges interconnect pairs of vanes. A threaded hub, fitted with bearing positioning shoulders, is welded and riveted to the five hub attachment flanges to complete the wheel.
