Abstract
An underframe construction for rolling stock vehicles comprising side sills disposed in parallel in the longitudinal direction of the underframe at the opposite outermost locations thereof, end sills connecting the side sills at the both ends in the longitudinal direction of the side sills, body bolsters arranged at positions at which a vertical load applied on the underframe is supported, center sills connecting each one of the end sills and each one of the body bolsters adjoining to one of the end sills, and a plurality of support members, each said support member being composed of upper horizontal flange, bottom plate and vertical web. The support members are disposed sequentially in the longitudinal direction of the underframe in such a fashion that the adjoining vertical webs of the support members are in contact to be bonded together and the both ends of the support members are secured to the side sills. The support members are able to support a load to be taken by the conventional cross beams and corrugated plates, thus enabling a reduction in weight and vertical dimension of the underframe.
