Abstract
A method for manufacturing a one-piece axle tube housing with localized sections of increased wall thickness includes providing a tube blank, inserting a mandrel having a reduced diameter profile, passing the tube through an extrusion die to conform the tube to the shape of the mandrel; and extraction of the mandrel from the tube to cause outward deformation of the tube at specific locations. A further reducing step may be used to form the final desired profile, including reduced inner and outer diameters along sections of the axle tube housing.
Claims4
An axle housing assembly, said axle housing assembly having support and load bearing components and a tubular member, said support and load bearing components being attached to said tubular member and defining load bearing regions on sections of said tubular member, wherein said tubular member has localized structural enhancements in said load bearing regions.
