The invention relates to the field of railway vehicles, and provides an end chassis, a vehicle chassis and a railway vehicle. The end chassis comprises a first-stage force transmission chassis, the first-stage force transmission chassis comprises a buffer beam and a stop beam, and a front end traction beam is arranged between the buffer beam and the stop beam; the second-stage force transfer chassis comprises a rear end traction beam connected to the side, away from the buffer beam, of the stop beam, and inclined pull beams connected with the stop beam are arranged on the two sides of the rear end traction beam in the vehicle width direction; the three-stage force transfer underframe comprises an integrally formed sleeper beam, and the sleeper beam is connected to the rear end traction beam; the four-stage force transmission underframe comprises a longitudinal beam connected to the sleeper beam and a first cross beam connected to the longitudinal beam, and a second cross beam is arranged at the end, away from the sleeper beam, of the longitudinal beam. According to the end chassis, the problem of longitudinal overlarge load can be solved, meanwhile, the problem that overall bearing of the end of a vehicle body cannot be achieved due to the existence of a large door area is solved, and then the end chassis structure capable of bearing longitudinal and transverse overlarge load at the same time is achieved.
本发明涉及轨道车辆领域,提供一种端部底架、车底架及轨道车辆。端部底架包括一级传力底架,包括缓冲梁和止挡梁,缓冲梁和止挡梁之间设置有前端牵引梁;二级传力底架,包括连接于止挡梁背离缓冲梁一侧的后端牵引梁,沿车宽方向,后端牵引梁的两侧设置有与止挡梁连接的斜拉梁;三级传力底架,包括一体成型的枕梁,枕梁连接于后端牵引梁;四级传力底架,包括连接于枕梁的纵梁以及连接于纵梁的第一横梁,纵梁背离枕梁的一端设置有第二横梁。该端部底架能够克服纵向超大载荷的问题,同时解决了车体端部因较大门区存在而无法实现整体承载的问题,进而达到能够同时承载纵向、横向超大载荷的端部底架结构。
