PURPOSE: An upper eccentric deep carrier having an oil circulation structure is provided to make oil always supplied to the outer bearing for lubrication of the outer bearing supporting a drive pinion. CONSTITUTION: An upper eccentric driving deep has a drive pinion supported by the inner and outer bearing and a rotary ring gear coupled with the pinion gear, to drive front wheels. An upper eccentric deep carrier has an oil inlet(1), an oil outlet(4), an oil passage(3), and oil guides(2). The oil inlet leads to the ring gear from the lower part of the drive pinion. The oil outlet leads to the ring gear from the upper part of the drive pinion. The oil passage is extended to the oil outlet from the oil inlet. The oil guide is formed to both sides of the drive pinion to prevent oil from flowing off into the inner bearing while oil passes through the oil passage. Therefore, the outer bearing is smoothly lubricated. |
