The invention relates to the technical field of rail vehicles, in particular to a pull rod mounting structure, a bogie and a rail vehicle. The pull rod mounting structure is used for being connected between a traction pull rod and a connected piece. The traction pull rod comprises a mounting block, a positioning sleeve and a fastener, the mounting block is fixedly connected with a connected piece,a positioning shaft is fixedly connected to a node of the traction rod and fixed between the mounting block and the connected piece, one end of the positioning sleeve is inserted into the positioningshaft, and the other end of the positioning sleeve is inserted into the connected piece. The fastener sequentially penetrates through the mounting block and the positioning sleeve to be connected with the connected piece in a fastened mode. According to the pull rod mounting structure, the stress state of the mounting bolt can be effectively improved, so that the mounting reliability of the traction pull rod is improved, the phenomena of loosening and breaking of a mounting bolt due to complex stress are effectively avoided, and the running safety and stability of a railway vehicle are greatly improved.

    本发明涉及轨道车辆技术领域,尤其涉及拉杆安装结构以及转向架、轨道车辆。该拉杆安装结构用于连接在牵引拉杆与被连接件之间,包括安装块、定位套筒以及紧固件,安装块与被连接件固定连接,牵引拉杆的节点上固接有定位轴,定位轴固定于安装块与被连接件之间,定位套筒的一端插装于定位轴内,定位套筒的另一端插装于被连接件内;紧固件依次穿过安装块和定位套筒与被连接件紧固连接。本发明所述的拉杆安装结构能够有效改善安装螺栓的受力状态,以提高牵引拉杆的安装可靠性,有效避免安装螺栓因受力复杂而导致的松脱和断裂现象发生,大大提高轨道车辆的运行安全性和稳定性。
