ABSTRACT:
A final gear-reduction unit is mounted at each wheel of a motor vehicle and is pivotally connected to one end of a lower control arm so that the unit may be turned to steer the vehicle. The other end of the lower control arm is pivotally connected to the frame of the motor vehicle on the side of the vehicle opposite the side on which the wheel is mounted. This allows a considerable amount of up and down movement of the wheel relative to the frame of the vehicle. The wheel is rotatably mounted to the gear-reduction unit with the gear-reduction unit positioned above the axle of the wheel to provide greater ground clearance for the drive to the gear-reduction unit. A pair of universal joints and a length of axle shaft connected between motor-driven differential gears of the vehicle and the gear-reduction unit provides the drive to rotate the wheel. This combination of universal joints and axle shaft allows the wheel to turn to steer the vehicle and allows up and down movement of the wheel relative to the frame of the vehicle. The axle shaft is mounted in a swept-back position so that the angle at the wheel between the axle shaft and the direction of movement of the motor vehicle is less than 90.degree. when the wheel is pointed straight ahead. The swept-back axle shaft decreases the turning radius of the motor vehicle by permitting a greater permissible turn angle on the inside wheel of the vehicle.
