ABSTRACT:
Pressurized lubricant from a vehicle transmission is inputted to a lubrication system of a four-wheel drive torque transfer mechanism through a cental oil passage in the transmission's output shaft. The transmission shaft coaxially joins with a shaft of the four-wheel drive torque transfer mechanism, said shaft also having a central oil passage. Lubricant leaves the central passage of the torque transfer mechanism shaft through radial oil passages to lubricate bearings and friction surfaces. Pump or splash lubrication is not used in the lubrication system for the four-wheel drive torque transfer mechanism.
