The invention relates to the technical field of railway vehicles, and provides a railway vehicle end chassis which comprises a sleeper beam, a buffer beam and a traction beam, the traction beam comprises a first beam body, a middle beam and a second beam body which are arranged in sequence, and the first beam body, the middle beam and the second beam body are arranged on the two sides of the sleeper beam in the width direction respectively; the first beam body is connected with the buffer beam, the middle beam is respectively connected with the first beam body and the sleeper beam, and the second beam body is connected with the sleeper beam; the first beam body, the middle beam and the second beam body are all formed by splicing and welding T-shaped section profiles. According to the railway vehicle end chassis, the defects that in the prior art, an end chassis traction beam is complex in structure, and weld joints are prone to deformation under the action of longitudinal force are overcome, and simplification and light weight of the traction beam are achieved.

    本发明涉及轨道车辆技术领域,提供一种轨道车辆端部底架,包括枕梁、缓冲梁以及牵引梁,所述牵引梁包括依次设置的第一梁体、中间梁以及第二梁体,所述第一梁体、所述中间梁与所述第二梁体分设于所述枕梁宽度方向的两侧,所述第一梁体与所述缓冲梁相连,所述中间梁分别连接所述第一梁体和所述枕梁,所述第二梁体与所述枕梁相连;所述第一梁体、所述中间梁以及所述第二梁体均采用T形截面型材拼焊而成。本发明的轨道车辆端部底架,解决了现有技术中端部底架牵引梁结构复杂、焊缝处在纵向力作用下易发生变形的缺陷,实现了牵引梁的简易化、轻量化。
