ABSTRACT:
A transfer arrangement for a four-wheel drive vehicle having an input shaft, a transmission, and a center differential. The transmission includes a first gear attached to the input shaft, a first counter gear attached to a countershaft in parallel with the input shaft to receive the rotation of the first gear, a second counter gear fixed to the countershaft and rotating therewith, and a second gear aligned with the input shaft and rotatably supported along the input shaft to receive the rotation of the second counter gear. High speed-side and low speed-side output parts are attached to the first and second gears respectively. The center differential is disposed between the high speed-side and low speed-side output parts. An engaging device disposed adjacent the center differential selectively engages with the high speed-side and low speed-side output parts.
