Torsion or flexure spring with constant cross-section surface for automobile and IC engine applications assembled from individual spring rods

摘要

The spring (11) has a constant cross-sectional surface provided by a number of individual spring rods (12) with a constant round or polygonal cross-section, each of which lies in contact with at least 2 other spring rods, the spring rods secured together in a bundle at least at the ends of the spring. The spring rods can be twisted in a helix about the longitudinal axis (A) of the spring and a number of springs, each assembled from a number of spring rods, can be twisted together.
