ABSTRACT:
A front and rear wheel road wheel drive apparatus transmits drive power from a drive power source in a motor vehicle to main and auxiliary drive road wheels and controls the transmitted drive power to improve operating performance of the motor vehicle such as turning performance in low- and medium-speed ranges and running stability in a high-speed range. The apparatus includes a first differential operatively coupled to the main drive road wheels for receiving the drive power from the drive power source, a second differential operatively coupled to the auxiliary drive road wheels and having clutch means for variably adjusting the amounts of drive power to be transmitted to the auxiliary drive road wheels independently of each other, a drive power transmitting mechanism for transmitting the drive power from the drive power source via the first differential to the second differential, and a speed increasing device disposed in the drive power transmitting mechanism for varying the rotational speed of the drive power supplied from the drive power source.
