The invention relates to the technical field of railway vehicles, and provides a vehicle body chassis and a railway vehicle. The vehicle body chassis comprises a middle chassis and a pair of end chassis, the middle chassis comprises a pair of boundary beams, a plurality of cross beams, hanging seats and a supporting frame, the pair of boundary beams and at least two cross beams are provided with the hanging seats, and the supporting frame is arranged on the cross beams; the pair of end underframes are arranged on the two sides of all the cross beams in the longitudinal direction respectively, each end underframe comprises at least two stages of force transmission parts, all the stages of force transmission parts are distributed in the longitudinal direction and connected with the edge beams, and each stage of force transmission part can transmit the longitudinal load to the pair of edge beams and the next stage of force transmission part or the cross beam. The boundary beams and the cross beams jointly bear the load of the oil tank, the supporting frame bears the load of the generator set, the cross beams lift the supporting frame and the generator set, and the vertical bearing strength of the vehicle body chassis is improved; longitudinal loads are transmitted and attenuated through the multi-stage force transmission components, the longitudinal bearing strength of the vehicle body chassis is improved, and the bearing strength of the vehicle body chassis in the longitudinal direction and the vertical direction is comprehensively improved.

    本发明涉及轨道车辆技术领域,提供一种车体底架及轨道车辆。车体底架包括中部底架和一对端部底架,中部底架包括一对边梁、多个横梁、吊挂座和支撑框架,一对边梁和至少两个横梁设有吊挂座,支撑框架设于横梁;一对端部底架分别设于所有横梁沿纵向的两侧,端部底架包括至少两级传力部件,各级传力部件沿纵向分布且均与边梁连接,每级传力部件能将纵向载荷传递至一对边梁和下一级传力部件或横梁。边梁和横梁共同承载油箱的载荷,支撑框架承载发电机组的载荷,横梁对支撑框架和发电机组进行托举,提高了车体底架的垂向承载强度;利用多级传力部件传递、衰减纵向载荷,提高了车体底架的纵向承载强度,综合提高了车体底架在纵向和垂向上的承载强度。
