The invention relates to the field of central traction devices, and provides a central traction device for a bogie, the bogie and a rail vehicle. The traction device comprises a traction beam assembly, a center pin assembly and a traction rubber pile, the traction beam assembly comprises a traction beam, two transverse stop mounting parts, two longitudinal stop parts and two vertical stop parts, and the two transverse stop mounting parts are correspondingly mounted at the two ends, extending in the length direction, of the traction beam; the two longitudinal stop parts are correspondingly installed on the two sides of the traction beam in the thickness direction, and the two vertical stop parts are correspondingly installed on the two sides of the traction beam in the thickness direction.According to the invention, the integrated installation of the transverse backstop, the longitudinal backstop and the vertical backstop on the traction beam is realized, so that the structure of the central traction device is more compact and reasonable, the installation space is greatly reduced, and the multifunctional installation interface requirement of the bogie and the space limiting area requirement of the bogie can be simultaneously met; and the difficulty of traction beam layout during bogie design is reduced.

    本发明涉及中央牵引装置领域,提供转向架用中央牵引装置、转向架及轨道车辆。包括牵引梁组成、中心销组成和牵引橡胶堆,牵引梁组成包括牵引梁、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,使中央牵引装置结构更加紧凑、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。
