The invention relates to the field of rail vehicle central traction devices, and provides a single-pull-rod central traction device for a bogie, the bogie and a rail vehicle. The traction device comprises a traction pin seat, vertical stops and a traction pull rod. The traction pin seat comprises a vehicle body sleeper beam connecting seat, a pair of transverse stop baffles, a traction pull rod mounting seat, and a pair of vertical stop mounting seats, wherein the pair of transverse stop baffles are oppositely arranged on the two transverse sides of the vehicle body sleeper beam connecting seat, and a transverse shock absorber mounting seat is formed at the bottom of one transverse stop baffle; the traction pull rod mounting seat comprises a pair of traction pull rod mounting supports which are arranged at intervals along one longitudinal side of the vehicle body sleeper beam connecting seat; and each of the pair of vertical stop mounting seats is formed at the bottom of each tractionpull rod mounting support. The pair of vertical stops are fixedly connected to the pair of vertical stop mounting seats respectively, and the stop ends face the longitudinal direction of the vehicle body sleeper beam connecting seat and are opposite in direction; and one traction pull rod is connected to the pair of traction pull rod mounting supports and the bogie frame. The single-pull-rod traction device can solve the problem that an existing single-pull-rod traction device is large in occupied space and difficult to install in a bogie.

    本发明涉及轨道车辆中央牵引装置领域,提供转向架用单拉杆中央牵引装置、转向架及轨道车辆。包括牵引销座、垂向止挡及牵引拉杆;牵引销座包括车体枕梁连接座;一对横向止挡挡板,相对设于车体枕梁连接座的横向两侧,一个横向止挡挡板的底部形成横向减振器安装座;牵引拉杆安装座,包括沿车体枕梁连接座的纵向一侧间隔设置的一对牵引拉杆安装支座;一对垂向止挡安装座,形成在每个牵引拉杆安装支座的底部;一对垂向止挡分别固定连接在一对垂向止挡安装座上,止挡端均朝向车体枕梁连接座的纵向且朝向相反;一根牵引拉杆连接在一对牵引拉杆安装支座与转向架构架上。本发明能够解决现有单拉杆牵引装置占用空间大而导致在转向架中安装困难的问题。
