The invention discloses a double-pull-rod slewing mechanism and a bogie. The slewing mechanism comprises two sets of connecting frames which are symmetrically arranged, a plurality of traction pull rods are arranged between the two sets of connecting frames, a mounting base is arranged on one side of each connecting frame, a mounting plate is arranged on one side of each mounting base, and a slewing stop is arranged at the end of the other side of each connecting frame. The traction device is simple and reliable in structure and low in cost, traction force and braking force are transmitted through cross connection of the two traction pull rods, meanwhile, the requirement that two vehicles pass through a small curve can be met, and the metal knuckle bearing has the good torsion deflection characteristic and can adapt to vehicle ramps, steps, curves and other road conditions; the two traction pull rods are mounted on the upper side and the lower side of the connecting frame respectively, and a certain vertical gap is reserved between the two traction pull rods and can adapt to opposite side rolling movement between the two vehicle bodies; the four rotation backstops are arranged, so that the overlarge rotation angle of the two axle bridges can be avoided; and meanwhile, the crossed double-pull-rod swing mechanism can be independently disassembled as a module, so that later inspection and maintenance are facilitated.

本发明公开了一种双拉杆回转机构及转向架，该回转机构包括两组对称设置有连接架，两组连接架之间设置有若干牵引拉杆，连接架的一侧均设置有安装座，安装座的一侧设置有安装板，连接架另一侧的端部设置有回转止挡。本发明结构简单、可靠，成本低，通过两牵引拉杆交叉连接共同传递牵引力和制动力，同时可满足两车过小曲线的要求，且金属关节轴承具有良好的扭偏转特性，可适应车辆坡道、台阶、曲线等路况；两牵引拉杆分别在连接架上下两侧安装并留有一定垂向间隙，可适应两车体间相对侧滚运动；通过设置有四个回转止挡，能够避免两轴桥过大的转动角度；同时，交叉双拉杆回转机构自成模块可单独进行拆卸，便于后期的检查和维护。
