The invention relates to the field of railway vehicles, and provides a middle chassis, a vehicle body chassis and a railway vehicle. The middle underframe comprises a pair of edge beams; the first cross beam is laid in the passenger room area, and the two ends of the first cross beam are connected between the pair of edge beams; the second cross beam is laid in the door area, and the two ends of the second cross beam are connected between the pair of edge beams; the passenger room floor is laid between the pair of edge beams, and the two ends of the passenger room floor are higher than the middle of the passenger room floor in the length direction of the vehicle. The middle chassis is beneficial to improving the riding experience of passengers in the vehicle driving process; the sitting stability and comfort are improved; the installation requirement of the bogie in a 100% low-floor vehicle is met to a certain extent; the rigidity and the stability of the whole middle underframe can be effectively improved, the overall bearing capacity of the vehicle is enhanced through the arrangement mode, and the safety of the vehicle under high-speed driving or complex road conditions is improved. And the middle underframe is also convenient for subsequent maintenance and overhaul work.

    本发明涉及轨道车辆领域,提供一种中部底架、车体底架以及轨道车辆。中部底架包括一对边梁;第一横梁,铺设于客室区,第一横梁的两端连接于一对边梁之间;第二横梁,铺设于门区,第二横梁的两端连接于一对边梁之间;客室地板,铺设于一对边梁之间,沿车长方向,客室地板的两端的高度高于客室地板的中部的高度。该中部底架有助于改善乘客在车辆行驶过程中的乘坐体验;提升乘坐的平稳性和舒适度;在一定程度上满足100%低地板车辆中转向架的安装要求;还可以有效提升整个中部底架的刚性和稳定性,这种设置方式不仅增强了车辆的整体承载能力,还提高了车辆在高速行驶或复杂路况下的安全性。该中部底架还方便后续的维护与检修工作。
