The invention provides a traction beam framework, a chassis front end structure and a railway vehicle, and relates to the technical field of railway vehicle traction beams. The traction beam frameworkcomprises an upper cover plate, two vertical plates, a middle partition plate, a lower cover plate and a mounting plate. The middle partition plate is arranged below the upper cover plate, one end ofthe lower cover plate is connected with a sleeper beam, and the other end of the lower cover plate extends below the middle partition plate; and the mounting plate is arranged between an extending end of the lower cover plate and the middle partition plate, and a coupler mounting hole is further arranged in the mounting plate. According to the traction beam framework provided by the invention, the mounting plate is fixed in a space formed by the middle partition plate, the lower cover plate and the two vertical plates so that the arrangement of an original mounting seat is omitted, space occupation is reduced, and a lightweight design is realized; and a height of a joint of the middle partition plate and the mounting plate can be correspondingly adjusted by bending the middle partition plate, the structure not only can guarantee position accuracy of the mounting plate and the mounting hole, but also can reduce the overall height of the mounting plate, and an effect of saving materialsis achieved.
本发明提供了一种牵引梁构架、底架前端结构和轨道车辆,涉及轨道车辆牵引梁技术领域,牵引梁构架包括上盖板、两个立板、中隔板、下盖板以及安装板,中隔板设置于上盖板的下方,下盖板的一端与枕梁相连,另一端延伸至中隔板的下方;安装板设置于下盖板的延伸端与中隔板之间,安装板上还设有车钩安装孔。本发明提供的牵引梁构架,将安装板固定在中隔板、下盖板以及两个立板形成的空间内,省去了原有的安装座的设置,减少了空间占用,实现了轻量化设计;中隔板与安装板相连的部位的高度可以通过对中隔板的折弯造型进行对应调节,该结构不仅可以保证安装板以及安装孔的位置准确度,还可以减小安装板的整体高度,起到节约材料的作用。
