ABSTRACT:
In an assembly for a vehicle of an engine and a four wheel drive power transmission system including a speed change device, a first power distribution device for distributionally dividing rotational power toward a pair of front wheels and a pair of rear wheels and a second power distribution device for rotationally dividing rotational power for the pair of either the front wheels or the rear wheels, wherein the engine, the speed change device and the first power distribution device are assembled in this order along a common central axis with one of two output shafts of the first power distribution device being shifted sideward of the central axis and directed toward the engine while the second power distribution device is mounted to a side of the engine with an input shaft thereof being directed toward and substantially aligned with the above-mentioned output shaft of the first power distribution device, a propeller shaft to connect the above-mentioned output shaft of the first power distribution device by a splined sleeve engagement, an intermediate portion of the output member of the second universal joint being rotatably supported by a radial bearing mounted to the speed change device, so that the speed change device, the first power distribution device, the first universal joint, the propeller shaft and the second universal joint may be preassembled together, and this preassembly may be axially abutted to the engine with the second power distribution device preassembled thereto.
