The invention relates to the field of rail vehicle bogies, and provides a single-pull-rod traction pin boss for a bogie, the bogie and a rail vehicle. The single-pull-rod traction pin boss for the bogie 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 extend downwards along one longitudinal side of the vehicle body sleeper beam connecting seat and are arranged side by side at intervals, the pair of traction pull rod mounting supports are located between the pair of transverse stop baffles, and through holes are formed in the pairof traction pull rod mounting supports; and the pair of vertical stop mounting seats are formed at the bottom of the traction pull rod mounting supports, and a mounting hole is formed in each verticalstop mounting seat. The technical problem that an existing single-pull-rod traction device is difficult to install in a bogie due to the fact that the occupied space is large can be solved.
本发明涉及轨道车辆转向架领域,提供转向架用单拉杆牵引销座、转向架及轨道车辆。转向架用单拉杆牵引销座包括:车体枕梁连接座;一对横向止挡挡板,相对设于所述车体枕梁连接座的横向两侧,其中一个所述横向止挡挡板的底部形成有横向减振器安装座;牵引拉杆安装座,包括沿所述车体枕梁连接座的纵向一侧向下延伸且并排间隔设置的一对牵引拉杆安装支座,一对所述牵引拉杆安装支座位于一对所述横向止挡挡板之间,一对所述牵引拉杆安装支座上均设有通孔;一对垂向止挡安装座,形成在每个所述牵引拉杆安装支座的底部,每个所述垂向止挡安装座上设有安装孔。本发明能够解决现有单拉杆牵引装置占用空间大而导致其在转向架中安装困难的技术问题。
