Abstract
A bellows shaped compression spring having a variable spring rate and formed of an elastomer having tensile characteristics such that the ratio of plastic strain to elastic strain is greater than 1.5 to 1, said spring being particularly adapted for use in the strut assemblies of light weight, low profile automobiles for minimizing noise, vibration and impact forces otherwise transmitted from the wheel to the vehicle body.
