In this four wheel drive power transmission system, there are included: a gearbox, affixed against an end of the engine, and coupled to it so as to receive rotational power therefrom; a power distribution device for four wheel drive, affixed against an end remote from the engine of the gearbox, coupled to the gearbox so as to receive rotational power from it, and provided with two power output shafts between which it distributes such rotational power; a first propeller shaft coupled to one of these power output shafts, and leading to a pair of vehicle wheels remoter from the engine; a second propeller shaft one end of which is rotationally coupled to the other of the power output shafts of the power distribution device; a power distribution device for a pair of vehicle wheels closer to the engine, mounted to the engine, and comprising a power input shaft aligned to generally point towards the power distribution device; and a universal joint rotationally coupled between the other end of the second propeller shaft and the power input shaft of the power distribution device. The second propeller shaft runs generally along and beside the combination of the engine, the gearbox and the power distribution device, with the universal joint being located, in the axial direction of that combination, on the side of the connection portion between the engine and the gearbox towards the gearbox. |
