The invention provides an underframe framework, a center sill underframe and a railway vehicle, the underframe framework comprises a center sill body, two buffer beams and two sleeper beams, the buffer beams are connected to the first end and the second end of the center sill body respectively, the two sleeper beams are connected to the center sill body respectively perpendicular to the trend of the center sill body, the two sleeper beams are located between the buffer beams and a bogie, and the two sleeper beams are connected to the first end and the second end of the center sill body respectively. And the bottom surface of the sleeper beam obliquely extends outwards and upwards from the middle shaft. According to the chassis framework, the structure that the middle beam body, the sleeper beam and the buffer beam are combined is adopted, the extending directions of the sleeper beam and the buffer beam are perpendicular to the middle beam body, the longitudinal bearing performance of the middle beam body is improved, the bearing requirement of a train is met, and the middle beam body is in a full-length structural form and can be conveniently matched with the size of a bogie interface; the installation requirement of the bogie connector is met, the installation convenience is improved, and the overall use performance of a railway vehicle is guaranteed.
本发明提供了一种底架骨架、中梁底架及轨道车辆,包括中梁本体、两个缓冲梁以及两个枕梁,中梁本体的一位端和二位端分别连接有缓冲梁,两个枕梁分别垂直于中梁本体的走向连接于中梁本体上,两个枕梁位于缓冲梁与转向架之间,枕梁的底面自中轴处向外上方倾斜延伸。本发明提供的底架骨架,采用中梁本体、枕梁和缓冲梁结合的结构,枕梁和缓冲梁的延伸方向分别垂直于中梁本体,增加了中梁本体的纵向承载性能,满足了列车的承载要求,中梁本体通长结构形式,便于实现与转向架接口尺寸的适配,满足了转向架接口的安装需求,提高了安装的便利性,保证了轨道车辆的整体使用性能。
