ABSTRACT:
An automotive differential is provided with pinion gears which are rotatably mounted in the differential housing. The differential housing is further provided with radially extending lubricant passages intersecting the pinion gear bores. Grooves or recesses on the rotating pinion bearing surfaces remove oil from the lubricant passages to provide lubrication of the bearing surfaces of the pinion gears. A conical thrust bearing is provided between the pinion and the differential housing to maintain stability of the pinion gear. Preferably, the lubricant passages extend from the interior cavity of the differential to the exterior to provide better recirculation of the oil through the interior cavity to provide improved cooling of the differential and prevent the lubricant from reaching excessive temperatures.
