The invention discloses a traction beam device, a chassis and a railway vehicle, and the traction beam device comprises two side beams which are arranged in parallel at a preset interval; the sleeper beam is vertically connected between the two edge beams; the first traction beam is perpendicular to the sleeper beam, and one end of the first traction beam is connected with the sleeper beam; the auxiliary traction beams are obliquely arranged on the side portions of the first traction beams, one ends of the auxiliary traction beams are connected with the edge beams on the corresponding sides, the other ends of the auxiliary traction beams intersect with the ends, away from the sleeper beams, of the first traction beams, and mounting bases are formed at the intersections of the auxiliary traction beams and the first traction beams and used for mounting car couplers. The first traction beam and the auxiliary traction beam act together to form a plurality of longitudinal load transmission paths, so that the longitudinal load transmission paths better meet the regional load transmission requirements and are better, and the load transmission capacity and the load transmission efficiency are improved; and the span size of the first traction beam is more flexible, so that the influence of a bogie limiting area on the structure of the traction beam device is reduced.

    本发明公开了一种牵引梁装置、底架及轨道车辆,包括:两个边梁,间隔预设距离的平行设置;枕梁,垂直连接于两个边梁之间;第一牵引梁,与枕梁垂直设置,第一牵引梁的一端与枕梁连接;至少一个辅助牵引梁,倾斜设置于第一牵引梁的侧部,辅助牵引梁的一端与对应侧的边梁连接,另一端与第一牵引梁远离枕梁的一端相交,且辅助牵引梁与第一牵引梁的相交处形成安装座,安装座用于安装车钩。第一牵引梁和辅助牵引梁共同作用,形成多条纵向载荷传递路径,使得纵向载荷传递路径更符合区域载荷传递需求,传递路径更优,提高了载荷传递能力及载荷的传递效率;且使得第一牵引梁的跨距尺寸更加灵活,从而降低了转向架限制区对牵引梁装置结构的影响。
