Abstract
The present invention relates to a suspension member and the process for constructing the suspension member. The suspension member comprises a folded single sheet of metal which is enlarged at one end to couple to a wheel assembly and U-shaped at the other end to pivotally connect with a vehicle frame. The process of constructing the suspension member comprises the steps of stamping a single sheet from a piece of stock, deforming the sheet to form a pocket defining the enlarged end, folding the sheet to form a substantially rectangular cross section and welding the seam between adjoining edges of the folded sheet. In order to support a spring assembly a tube extends through the folded sheet and cooperates with the spring assembly to attach the latter to the folded sheet.
