Tubular axle housing assembly with varying wall thickness

Abstract From the Canadian patent

A one-piece axle housing assembly is provided with localized sections of increased wall thickness to address different load or strength requirements along the length of the assembly. In one embodiment the assembly includes a tubular member defining a first normal load region having a first inner diameter and a first outer diameter and defining a first wall thickness. The member further includes a first load bearing region configured to support a first load bearing component and having a second inner diameter equal to the first inner diameter and a second outer diameter greater than the first outer diameter and defining a second wall thickness greater than the first wall thickness.
