Abstract: An axle assembly and method for assembling such axle assembly for a vehicle are disclosed. The axle assembly may comprise meshed ring and pinion gears, a center housing portion, and left and right leg housing portions. The center housing portion may include a center housing defining a center cavity in which the bevel gear is disposed, and at least one channel having an entrance port into the center cavity. The axle assembly may include a first conduit configured to branch off of the first channel in a first direction and a second conduit configured to branch off of the first channel in a second direction. Such channels and conduits may be integral to the center housing or substantially external to the center housing.

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.

Abstract: A shroud assembly and method for assembling such shroud assembly for a vehicle are disclosed. The shroud may comprise a collar joined to a nose cap. The shroud assembly may comprise the collar, the nose cap, and meshed ring and pinion gears. The collar may define at least one port and the nose cap may define an aperture. These allow lubricating fluid to escape outside of the shroud and thus be removed from the immediate vicinity of the rotating ring and pinion gears.

Abstract: Methods and systems provide a simulation of cavitation damage. In one implementation, a computer-implemented method simulates a potential for cavitation damage. According to the method, data defining a modeled component is imported to a flow solver tool. The flow solver tool simulates a liquid that flows through the modeled component. Voids created by the flow of the liquid cause a plurality of vapor implosion pressure events. The method further includes displaying a histogram showing a portion of the modeled component. On the histogram, locations of the plurality of vapor implosion pressure events are visually distinguishable on a surface of the portion of the modeled component.
