Title:
WHEEL FOR WIDE COMMERCIAL VEHICLE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/165068
Kind Code:
A1
Abstract:
The present invention relates to a wheel for a wide commercial vehicle and a method for manufacturing same, more specifically to a new single wheel-type wheel for a wide commercial vehicle having a single rim part and a single hub formed as an integrated body in the center of the internal diameter of the rim part, and to a method for manufacturing same. To that end, after pre-forming in which a semi-solid is forged using an aluminum-wrought alloy material, an improved new single wheel-type structure, having a single rim part and a single hub part formed as a single body in the center of the internal diameter of the single rim part, is formed by means of processes such as a flow-forming process, and thus the present invention provides a wheel for a wide commercial vehicle and a method for manufacturing same allowing not only a reduction in the weight of the product, but also allows reductions in material usage and production costs, decreased forging cycle time, and increases in the tensile and fatigue strengths due to a change in materials used.
