ABSTRACT:
The invention is a suspension spring apparatus for a vehicle wherein the suspension spring maintains a linear alignment irrespective of the position of the articulating strut, where the articulating strut is selected from the group consisting of: control arms, axle arms, solid axles, adjustable spring tensioning devices, and longitudinal struts. The apparatus is comprised of a compression spring mounted between a pivoting lower seat and a pivoting upper seat, where the pivoting lower seat is coupled to the articulating strut and the pivoting upper seat is coupled to a support element. The support element is static, and serves to support the suspension system, and to distribute the forces generated by the suspension system. The pivoting lower seat and the pivoting upper seat can, in combination, pivot through substantially the same plane as the articulating strut, such that when there is a change in angle of the articulating strut with respect to the support element there is a commensurate change in the pivoting lower seat and the pivoting upper seat. The compensation maintains the compression spring aligned linearly between the pivoting lower seat and the pivoting upper seat. Compression and expansion occurs along the centerline of the spring, and there is no transverse curvature, or other deformation of the spring.
