Abstract

A front air suspension system for a mobile vehicle such as a medium or heavy truck or school bus. The system has horizontally mounted shock absorbers engaged at a rear end to each of the frame rails of the chassis and at a forward end to a bell crank. The bell crank is pivotably engaged in its center to the frame rails and on its opposite side to an upper portion of a vertical link. The lower portion of the vertical link is engaged to a trailing beam. An air spring is engaged between each frame rail and the trailing beams. The bell crank transfers energy between the shock absorber and the air springs to dampen air spring induced movement of the chassis. The vertical link and bell crank combination provide lateral support for the sprung mass.
