Abstract
Abstract In the four-wheel-drive motor vehicle of transversely-disposed type, a front differential and a center differential are arranged coaxially on the axle line of front wheels, and an engine and a transmission are disposed transversely to the vehicle body in the rear of these differentials. This arrangement can relieve one-sided action of the vehicle body weight on the front wheels.
