Abstract
A transfer gear has high speed and low speed modes with two wheel drive or four wheel drive. A main drive shaft has a main drive gear rotatably mounted on it. A main shaft is coaxial with the main drive shaft and carries a speed change gear rotatably on it and drives the rear wheels. The main shaft further rotatably supports a front drive gear which transfers power to the front wheels. A counter gear assembly provides a speed reduction between the main drive gear and the speed change gear. A first switching mechanism connects the main drive shaft to either the main shaft or the main drive gear. A second switching mechanism connects the main shaft either to the speed change gear or to the front drive gear, or disconnects both the speed change gear and the front drive gear from the main shaft, or connects both the speed change gear and the front drive gear to the main shaft.
