ABSTRACT:
A railcar shock insulated suspension system is provided with unique variable rod springs and co-related variable rate friction damping means. Each rod spring includes an elongated solid body of elastomeric material which, when subjected to radially directed compression loads and allowed to deform freely without rotation, produces a non-linear or variable spring rate proportional to the ratio of the areas of its loaded to unloaded surfaces. Rod springs constitute the main suspension spring elements, and additionally may constitute the damping means spring elements, if desired.
