Abstract: An articulated vehicle including two wheeled sections hinged together in the middle of the vehicle by a universal movement joint enabling relative pivoting about three axes extending at right angles to each other through the center of the vehicle. A hydraulically operated strut extends between the two vehicle sections and is universally pivoted at its ends to the two vehicle sections to control the relative pivoting of the two vehicle sections about a transverse axis while enabling the middle of the vehicle to be raised or lowered for various reasons. The vehicle is steered by a pair of hydraulically operated steering struts extending between the two vehicle sections on the opposite sides of the universal movement joint.
