Abstract
A final drive comprising a lubrication system is provided. The final drive comprises an axle housing and a differential housing. The differential housing is in alignment with the axle housing, and they share a longitudinal axis. The final drive further comprises a lubricant ring having a lubricant ring inner diameter. The lubricant ring travels about an inner surface of the axle housing. Further, the final drive has a longitudinal axis region, defined as the region formed by the lubricant ring inner diameter. The lubrication system comprises a lubrication inlet in fluid communication with a lubricant outlet. The lubrication inlet is disposed in the axle housing to capture a portion of the lubricant ring. The lubricant outlet is disposed in the differential housing to distribute the portion of the lubricant ring generally to the longitudinal axis region.
