The invention relates to the technical field of railway vehicles, in particular to a railway vehicle chassis structure. The railway vehicle chassis structure comprises a chassis body and a built-in floor arranged on the chassis body. The structure of the double-layer cavity of the sleeper beam can be suitable for different working conditions, and when an external axle box is adopted by a bogie, a wire passing pipe is preferentially arranged in the lower-layer cavity of the sleeper beam, so that threading operation and maintenance of the sleeper beam are facilitated; when the bogie adopts the built-in axle box, the wire passing pipe is preferentially arranged in the upper-layer cavity of the sleeper beam so as to ensure the integrity of the lower-layer cavity and ensure the running safety of a vehicle, and meanwhile, the upper-layer cavity can be used for threading so as to solve the problem of cable arrangement at the part. In addition, the sleeper beam structure can meet the requirement for installation of a bogie with a built-in axle box, the weight of the sleeper beam structure can be reduced by more than one ton compared with a traditional bogie with an external axle box, and the vehicle has the excellent light weight effect.

    本发明涉及轨道车辆技术领域,具体涉及一种轨道车辆底架结构;该轨道车辆底架结构,包括底架本体和设置在底架本体上的内装地板;本发明枕梁的双层型腔的结构可以适用不同的工况,当转向架采用外置式轴箱时,过线管优先设置在枕梁的下层型腔中,以方便枕梁穿线操作和维护;当转向架采用内置式轴箱时,过线管优先设置在枕梁的上层型腔中,以保证下层型腔的完整性,确保车辆运行安全,同时上层型腔可用于穿线,解决该部位线缆布置问题。除此之外,本发明的枕梁结构能满足采用内置式轴箱的转向架安装,比传统外置式轴箱转向架能减重1吨以上,使车辆具有优越的轻量化效果。
