Abstract:
The suspension includes a moveable load arm assembly adapted to support a vehicle axle, at least one elliptical cross-section rod spring carried by the load arm assembly in load bearing relation with a vehicle body, a frictional damping surface connected to the body adjacent the load arm assembly, a frictional damping element, and a tapered operator carried by the load arm assembly in underlying relation with each rod spring such that one component of a load bearing force transmitted from the load arm assembly is applied to the rod spring as a transverse load bearing compressive force only, while a perpendicular component thereof is applied to and urges the damping element toward the friction surface. The suspension is suited for usage in railcar and rubber tired vehicle suspensions.
