ABSTRACT:
The present invention includes a suspension system for use with railroad freight car trucks, or the like, wherein vertical, transverse and longitudinal movements of the car body sprung mass are restrained and isolated from rail-induced excitations and dampened by captive elastomeric means. This system employs crossed levers to restrain said sprung mass parallel with respect to the supporting railroad track.
