TRAILING ARM SUSPENSION WITH OPTIMIZED I-BEAM

摘要

A suspension system includes a pair of trailing arms (112) extending between frame brackets (18) and a wheel-carrying axle (22). Each trailing arm (112) comrises an I-beam portion having a web section and first and second flanges, wherein the thickness of at least one of the flanges vaires along a length thereof. The trailing arms (112) are welded directly to the axle (22).
