  • Trailing arm suspension with optimized I-beam
    Patent number: 7484744
    Abstract: A suspension system for suspending a vehicle frame above a plurality of ground-engaging wheels includes a wheel-carrying axle comprising a first end a second end, and a pair of frame bracket assemblies each comprising a resiliently-bushed pivotable connection defining a pivot axis, wherein the frame bracket assemblies are operably coupled to opposite sides of the frame bracket, and wherein the resiliently-bushed pivotable connection comprises a substantially cylindrically-shaped bushing. The suspension system also includes a pair of trailing arms each comprising a first end operably coupled to the first end and the second end of the axle, respectively, and a second end comprising an aperture that receives the bushing of one of the frame bracket assemblies therein, wherein the aperture of the second end of each trailing arm is nonsymmetrical, thereby causing a nonsymmetrical compression of the bushing about the pivot axis.
