Abstract

A power transfer unit includes a non-parallel gear set and a parallel gear set integrally packaged within a housing. The housing includes an extension portion that connects the power transfer unit to a transmission assembly. The extension portion is formed having a structural web with one or more cavities. These cavities include inner cavities that define a portion of the interior volume of the housing and may also include outer cavities that open to the outer side of the housing. The web between cavities provides structural rigidity for the power transfer unit, while the cavities minimize the weight of the power transfer unit.
