ABSTRACT:
A suspension spring comprises a plurality of spring elements, each comprising a central portion, a pair of torsional helical coils adjacent thereto, and respective arms coupled to the respective helical coils. A load applied to the central portion of each spring element by a load distributor is reacted by the distal ends of the respective arms, thereby causing flexure of the arms and torsional displacement of the helical coils. The helical coils provide a means for increasing spring compliance and for reducing the stress in the respective arms and central portion of the spring elements, while the plurality of spring elements provides for improved lateral stability in comparison with a single element spring having the same vertical compliance.
