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.

Dependent claims

A vehicle wheel comprising:

a plurality of circumferentially spaced radial vanes extending from an inner diameter to an outer diameter;
a plurality of rim retaining flanges extending between and interconnecting alternate pairs of said vanes at said outer diameter;
a plurality of hub attachment flanges extending between and interconnecting alternate pairs of said vanes at said inner diameter, said hub attachment flanges being displaced circumferentially from said rim retaining flanges such that the circumferential midpoints of said hub attachment flanges are not radially aligned with the circumferential midpoints of said rim retaining flanges;
said vanes, said rim retaining flanges, and said hub attachment flanges being disposed to afford unobstructed axial clearance through said wheel;
and
a hub fitted into said inner diameter and attached to said hub attachment flanges.
