Patent ID: 6887177

Claim:
A power transfer arrangement for a four-wheel drive vehicle having an input shaft to which rotation from a power source is transmitted, a transmission which converts the rotation of said input shaft into high and low speeds, and a center differential aligned with said input shaft to distribute the rotation output from said transmission to front and rear wheels of the vehicle, comprising the improvement wherein said transmission includes a first gear attached to said input shaft, a first counter gear attached to a countershaft in parallel with said input shaft to receive the rotation of said first gear, a second counter gear attached to said countershaft and rotating therewith, and a second gear aligned with said input shaft and rotatably supported along the input shaft to receive the rotation of said second counter gear, high speed-side and low speed-side output parts attached to said first and second gears respectively, said center differential being disposed between said high speed-side and low speed-side output parts, and an engaging device disposed adjacent to said center differential to selectively engage with said high speed-side and low speed-side output parts.
