  • Patent number: 4313511
    Abstract: A land vehicle has front, rear and two side wheels arranged in a diamond-shaped configuration to provide a triple track mode of operation. A steering mechanism mounted on the vehicle frame controls one of the front and rear wheel assemblies. Each one of the other wheel assemblies includes an articulated suspension having a suspension arm pivotally connected to the frame and having its wheel journaled for rotation thereon. A device is controlled by the steering mechanism and rotates the arm about its pivotal axis to tilt its suspension into the direction of a turn of the vehicle to facilitate its maneuverability. Another device controls the movement of the suspension arm for the driving wheel to maintain it in engagement with the terrain. The steering mechanism includes devices for causing the side wheels to turn in unison with the main steering wheel to facilitate steering of the vehicle.
