The invention discloses a railway vehicle outside-sleeper structure. A center filler is fixed to a lower cover plate of a sleeper beam through a bolt, the back end of a traction beam and the sleeper beam are welded and fixed, a connector of a
bogie is arranged between two webs of the sleeper beam, and the lower cover plate on the parts, on the two sides of the center filler, of the sleeper beam is provided with installing holes. The front section of the traction beam is provided with a vehicle hook installing base, a large beam is transversely arranged between the traction beam and side beams, the large beam is located near the vehicle hook installing base, a corrugated floor is laid between the large beam and the sleeper beam, a flat floor is laid between the large beam and an end beam, a panel is laid on the upper surface of the traction beam, and the front end of the traction beam is of a horn
mouth structure. According to the outside-sleeper structure, a
high load is achieved through a series of improvements and design, the maintaining frequency is low, manufacturing is easy, and the railway vehicle outside-sleeper structure can well adapt to the operation characteristics of meter-gauge rail intercity passenger trains due to the small curve
radius.
