Abstract

The present invention provides a integral subassembly for the power train of an all wheel drive automotive vehicle. The subassembly includes a final drive unit coupled to a transmission output. The final drive unit itself includes a torque multiplier and an output adapted to provide power to the front wheels of the vehicle. Also included in the subassembly is a front differential coupled to the final drive's output. The front differential includes a left front wheel output and a right front wheel output. A power transfer unit in the subassembly is also coupled to the transmission output and provided with a non-parallel gear set and a rear driveline output, the latter being adapted to provide power to the rear wheels of the vehicle. The power transfer unit is coupled to the transmission output independently of the final drive unit. Finally, a housing commonly encloses the final drive unit, front differential and power transfer unit allowing them to be integrally provided as a subassembly.
