Vehicle suspension and steerage system

摘要

A suspension and steerage system is disclosed for a wheel supported vehicle. A suspension arm assembly of parallelogram configuration is pivotally attached to one side of the main frame and freely supports a wheel spindle. The piston rod of a hydraulic motor interconnects opposite wheels, and a lever structure is provided which, in response to pivotal oscillation of one wheel, axially activates the piston rod to transfer reactive forces to the opposite side of the main frame, and serves to level the plane of the main frame. The hydraulic motor can further be equallized to lock out further movement of the wheels, thereby stabilizing the vehicle in a static condition.
