摘要： A suspension system for a vehicle frame from a steering axle has first and second controllable rate springs mounted above the steering axle and below the frame to support a portion of vehicle weight. A trailing V-link member is mounted to pivot on its vertex on a cross-member of the frame forward of the steering axle. The opposite ends of the V-link member are pivotally connected to opposing ends of the steering axle allowing the V-link member to constrain fore to aft movement of the steering axle, lateral displacement of the steering axle and frame roll. A pitman and trailing draglink from a steering gear on the frame to the steering axle controls steering. First and second shackle assemblies depend from the frame aft of the steering axle. First and second leading arms are suspended from the shackle assemblies to permit longitudinal translation of the first and second leading arms relative to the frame. The leading arms are rigidly connected to the opposing ends of the steering, axle to constrain rotation of the steering axle and the trailing V-link member about the vertex of the V-link member. Shock absorbers for damping motion between the steering axle and the frame are positioned adjacent the controllable rate springs.

摘要： A suspension system for the steering axle of a vehicle chassis includes a right side air spring and a left side air spring. In the preferred embodiment leading rigid arms link each end of the steering axle to a pivoting mount on the chassis and transmits brake reaction torque as a lifting force to the chassis. Spring half leaf trailing links connect each end of the steering axle to the chassis, rigid leading arms provide anti-roll capacity as well as help in locating and stabilizing axle position.

摘要： A single air spring positioned under one side of a vehicle provides side to side leveling of the vehicle. Main springs support the vehicle above a pair of coaxial wheels or coaxial wheel sets. An auxiliary, inflatable air spring is positioned to provide additional support to the vehicle above one of the wheels. Deflection of the main springs from a norm or index is indicated by movement of tie rods mounted from the wheels, axle, or base of the main springs relative to the suspended portion of the vehicle. One tie rod is directly linked to a free end of an equalizer lever whereby the equalizer lever moves in the same direction as the tie rod. The second tie rod is coupled to the remaining free end of the equalizer lever by a rotatable rod, whereby the appropriate end of the equalizer lever moves in the direction opposite to the tie rod. The equalizer lever is suspended at its center from an actuation lever for a valve used to control inflation and deflation of the auxiliary air spring. The actuation lever has a pivot axis fixed with respect to the suspended vehicle, so movement the center point of the equalizer lever results in movement of the actuation lever. The direction of movement of the actuation lever results in valve action to inflate, deflate, or hold the pressure in the auxiliary air spring.
