ABSTRACT:
An improved suspension system for an uncrowned wheel rolling on a flat track characterized by a wheel frame assembly including a wheel frame and at least one uncrowned wheel connected in supporting relation with the frame and adapted to be seated in rolling engagement with a flat track, a load supporting bed, and a plurality of flexural struts interconnecting the bed in supported relation with the frame, each of said struts being disposed in a plane passing through the center of the uncrowned wheel surface along a line substantially bisecting the line of contact established between the wheel surface and the flat surface of the truck and characterized by a modulus of elasticity sufficient for maintaining the axis of rotation for the wheel in substantial parallelism with the line of contact established between the surfaces of the wheel and track.
