Abstract
A final drive unit for a motor vehicle includes a carrier housing integrally formed with a final drive housing and provided to store a lubricating oil therein, a pinion drive shaft rotatably supported within the final drive housing by a pair of bearings, an oil supply passage formed integrally with the final drive housing for lubricating the bearings and having a supply opening in communication with a cavity in the carrier housing, and a baffle member mounted within the carrier housing adjacent to the supply opening of the oil supply passage. The baffle member includes a baffle wall provided to cover a lower portion of the oil supply passage for maintaining a portion of the lubrication oil within the oil supply passage so as to permit the lubricating oil to adequately lubricate the bearings even when the motor vehicle is tilted to a maximum angle of inclination.
