Abstract
A machine axle housing includes a central body having an oil reservoir and a pair of axle legs. The central body includes a ring gear, an oil channel, and oil port for conveying oil through an oil conduit to each leg. Machine brakes within the central body include at least one disc rotatably adapted to centrifugally move oil radially outwardly of the brakes. A second oil channel collects oil from the disc, and a passageway extends from the second oil channel back to the central body to return oil from the legs back to the central body. The ring gear, first oil channel and first oil conduit define a first oil lubrication sub-system for moving oil from the central body to right and left legs, and the disc, second oil channel, and passageway define a second oil lubrication sub-system for moving oil from the legs back to the central body.
