The invention belongs to the field of railway vehicles, and particularly discloses a front-end chassis structure, a vehicle chassis and a railway vehicle. The front end chassis structure comprises a front end assembly and a traction beam assembly. The front end assembly includes a stop beam and a front cross beam extending laterally and spaced longitudinally from each other, the stop beam forward of the front cross beam. The draw beam assembly comprises a car coupler mounting seat connected with the front cross beam and two draw beams which are connected with the car coupler mounting seat and extend longitudinally, and each draw beam comprises a main body part located on the rear side of the car coupler mounting seat and a reinforcing part located on the front side of the car coupler mounting seat; the reinforcement portion extends forward from the coupler mount to the stop beam. According to the front-end chassis structure, the force transmission path can be optimized, and therefore the strength of a vehicle body is improved.

    本发明属于轨道车辆领域,具体公开了一种前端底架结构、车底架以及轨道车辆。前端底架结构包括前端总成和牵引梁总成。所述前端总成包括横向延伸并且纵向彼此间隔开的止挡梁和前横梁,所述止挡梁位于所述前横梁的前方。所述牵引梁总成包括与所述前横梁连接的车钩安装座以及与所述车钩安装座连接并且纵向延伸的两个牵引梁,每个牵引梁均包括位于所述车钩安装座后侧的主体部以及位于所述车钩安装座前侧的增强部,所述增强部从所述车钩安装座向前延伸到所述止挡梁。本发明提供的前端底架结构能够优化传力路径,从而提高车体强度。
