Abstract

Abstract A heavy-duty vehicle suspension assembly is provided that includes an axle assembly having opposing suspension arm mounting faces. A pair of modular suspension arm assemblies are secured to the axle assembly with the suspension arm assemblies extending outwardly from the axle assembly in opposite directions from one another. Each suspension arm assembly includes a first arm portion (24) having a first end (26) secured to the mounting face and extending to a second end (28). A second arm portion (32) is secured to the second end and has a spring seat (36) with a spring supported on each of the spring seats of the suspension arm assemblies for damping forces transmitted through the axle assembly. The first and second arm portions include mounting surfaces (30,34) that overlap one another in a plurality of positions to permit the arm portions to be secured to one another in a plurality of configurations that accommodate numerous spring heights (X) and pinion angles. The first and second arm portions may be constructed as separate castings. Once the desired spring height and pinion angle have been determined, the arm portions are oriented relative to one another in a configuration to obtain the desired spring height and pinion angle. The arm portions are secured to one another to retain the arm portions in the configuration, such as by drilling holes and using fasteners (40) to secure the arm portions to one another.
