ABSTRACT:
The present invention discloses a multiple axle articulated suspension structure and system for vehicles wherein road and tire excitations of each axle are isolated from their opposing axle, as well as from the sprung mass. This is accomplished in a preferred embodiment of my invention via deflections in a combination integrally damped multiple spring means system including a pressure resistant air spring and a self-damping compressive resistant elastomer having high hysteresis characteristics, operatively providing a progressively increasing spring rate. The elastomer is disposed entirely within and functions in parallel with the air spring, such that the compressive resistance of the air spring supplements or augments that of the elastomer, and the high hysteresis of the elastomer serves to dampen fluctuations or deflective excitations induced in the air spring during what as known as jounce conditions.
