The invention relates to the technical field of rail vehicles, and provides a traction beam, a central traction device, a bogie and a rail vehicle. The traction beam comprises a traction beam body, two transverse stop installation parts, two longitudinal stop parts and two vertical stop parts, the two transverse stop installation parts are correspondingly installed at the two ends, extending in the length direction, of the traction beam body, and the two longitudinal stop parts are correspondingly installed on the two sides, in the thickness direction, of the traction beam body. And the two vertical stop parts are correspondingly mounted on the two sides of the traction beam body in the thickness direction. The integrated installation of the transverse stop, the longitudinal stop and the vertical stop on the traction beam is achieved, so that the traction beam is more compact and reasonable in structure, the installation space is greatly reduced, and the multifunctional installation connector requirement of the bogie and the space limiting area requirement of the bogie can be met at the same time. The difficulty of traction beam layout during bogie design is reduced.

    本发明涉及轨道车辆技术领域,提供牵引梁、中央牵引装置、转向架及轨道车辆。该牵引梁包括牵引梁本体、两个横向止挡安装部、两个纵向止挡部和两个垂向止挡部,两个所述横向止挡安装部对应安装于所述牵引梁本体沿长度方向延伸的两端,两个所述纵向止挡部对应安装于所述牵引梁本体沿厚度方向的两侧,两个所述垂向止挡部对应安装于所述牵引梁本体沿厚度方向的两侧。本发明实现了横向止挡,纵向止挡和垂向止挡在牵引梁上的一体化集成安装,使得牵引梁结构更加紧凑、合理,大大缩小了安装空间,能够同时满足转向架多功用安装接口要求和转向架空间限制区域要求,降低了转向架设计时牵引梁布局的难度。
