Abstract:
In a front axle air suspension for a vehicle having a chassis including fore-and-aft extending side beams having laterally projecting shock absorber mounts thereon, a front axle with front wheels mounted on its opposite ends, a pair of downwardly extending brackets mounted on said side beams in front of said front axle, a pair of fore-and-aft extending spring beams each of which is connected adjacent its trailing end to said axle at a location thereon underneath one of said chassis side beams and having an eye at its front end pivotally connected to one of said pair of brackets, and an assembly duplicated on each side of said vehicle resiliently interconnecting and supporting said chassis on and above said axle and said spring beams,each said assembly comprising a multi-functional component having a central body portion seated in clamped relationship on the trailing end of a said spring beam at a location directly above said axle and directly beneath a chassis side beam and having fore-and-aft air spring support formations projecting in cantilever relationship from opposite sides of said central body portion, said central body portion having on its front and rear sides and inboard of said air spring support formations seats for the bight portions of downwardly extending U-bolts which clamp said central body portion to said axle with the trailing end of said spring beam clamped therebetween, a second laterally projecting shock absorber mount on said central portion and a track rod attachment bracket on the central body portion of at least one of said multi-functional components projecting inwardly toward the center of said chassis, an air spring mounted in load supporting relationship between each of said air spring support formations and the adjacent chassis side beam, a shock absorber pivotally connected at its upper end to a said first shock absorber mount on a side beam and pivotally connected at its lower end to a said second shock absorber mount on said central body portion, a track rod frame bracket mounted on the inner side of one of said side beams, and a track rod pivotally connected at one end to said track rod frame bracket and pivotally connected at its opposite end to said track rod attachment bracket for supporting lateral loads received by the suspension.
