ABSTRACT:
A shock-absorbing spring for vehicles has a deformed egg-shaped cross section different from a conventional round cross section. In comparison to the conventional spring under a same length, the invention has a lighter weight and a longer spring travel. Moreover, stress can be uniformly distributed toward two sides of the cross section of the invention so that the invention can bear more stress and lengthen its service life.
