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 center pin bush mounting cylinder, a traction beam body, two transverse stop mounting parts, two longitudinal stop parts and two vertical stop parts, the traction beam body comprises a first traction beam main body and a second traction beam main body, and the first traction beam main body and the second traction beam main body are correspondingly connected with the two opposite sides of the center pin bush mounting cylinder respectively; the two transverse stop mounting parts are correspondingly connected with the first traction beam main body and the second traction beam main body respectively, the two longitudinal stop parts are correspondingly installed on the two opposite sides of the center pin bush mounting cylinder, and the two vertical stop parts are correspondingly installed on the two opposite sidesof the center pin bush mounting cylinder. The traction beam is compact and reasonable in structure, the installation space is greatly reduced, the multifunctional installation connector requirement ofthe bogie and the space limiting area requirement of the bogie can be met at the same time, and the layout difficulty of the traction beam 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。该牵引梁包括中心销套安装筒、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,牵引梁本体包括第一牵引梁本体和第二牵引梁本体,第一牵引梁本体和第二牵引梁本体分别与中心销套安装筒的相对两侧对应连接,两个横向止挡安装部分别与第一牵引梁本体和第二牵引梁本体对应连接,两个纵向止挡部对应安装于中心销套安装筒的相对两侧,两个垂向止挡部对应安装于中心销套安装筒的相对两侧。该牵引梁的结构紧凑、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。
