The embodiment of the invention provides a chassis assembly of a railway vehicle and the railway vehicle. The chassis assembly of the railway vehicle comprises a pair of edge beams, a pair of end beams and connecting angle plates. The pair of edge beams extends in the length direction of the under-frame assembly, and first notch parts are arranged at the ends of the edge beams. The pair of end beams are arranged at the two ends of the edge beams respectively, the two ends of each end beam are connected with the ends of the pair of edge beams respectively, the two ends of each end beam are each provided with a second notch part, the first notch parts and the second notch parts are spliced in a one-to-one correspondence and crossed mode, and connecting notches are defined by the splicing positions of the first notch parts and the second notch parts. The connecting angle plates are embedded in the connecting notches, and the edges of the connecting angle plates are spliced with the edges of the connecting notches in a one-to-one correspondence mode. By the adoption of the scheme, the total length of the welding seam is increased, the connection reliability is improved, the connecting corner plate can reinforce the connecting position, the installation space cannot be additionally occupied, and therefore follow-up installation and maintenance of equipment cannot be affected.
本申请实施例中提供了一种轨道车辆的底架总成及轨道车辆。其中,轨道车辆的底架总成包括一对边梁、一对端梁以及连接角板。一对边梁沿底架总成的长度方向延伸,边梁的端部均设置有第一豁口部。一对端梁分别设置在边梁的两端,每根端梁的两端分别与一对边梁的端部连接,端梁的两端均设置有第二豁口部,第一豁口部与第二豁口部一一对应地交叉拼接,并且第一豁口部与第二豁口部的拼接处围合成连接豁口。连接角板嵌设在连接豁口处,连接角板的边缘分别与连接豁口的边缘一一对应的拼接。采用本申请中的方案,增加焊缝的总长度,提高连接可靠性,连接角板可对连接处进行加固,而且,不会额外占用安装空间,从而不会影响后续的设备的安装和维护。
