Abstract

A drive axle housing system may minimize churning of splash and spray oil within a drive axle housing. The drive axle housing system includes apparatus for incorporation into the axle, the apparatus including an oil churning reduction member that may be affixed to the interior walls of the axle housing. The oil churning reduction member includes interior surfaces adapted to closely align with interior moving gear components of the axle to minimize efficiency losses due to oil movement. The system may also incorporate an annular element, affixed to the axle housing and closely aligned with the backside of a ring gear component of the differential axle. The combined use of the member and the element may substantially reduce torque losses attributable to excessive churning of oil.
