Abstract
A shock insulated suspension system is provided with unique variable rate 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.
Claims3
A rubber tired vehicle suspension for transmitting a load between an axle and a body of a rubber tired vehicle, which suspension comprises load bearing spring means comprising at least one resilient rod spring composed of an elongated body of elastomeric material having an elliptical cross-section and opposed elongated longitudinal load bearing surfaces;
- and mounting means for attachment between the body and axle of a rubber tired vehicle, said mounting means carrying said rod spring in a position such that load bearing compressive forces only are transmitted to said load bearing surfaces transversely of the rod spring longitudinal axis with respect to said mounting means, while simultaneously therewith permitting the unloaded rod spring surfaces to bulge freely.
