Bogie

The embodiment of the invention provides a bogie. The bogie comprises two side beams; two connecting seats, one connecting seat is connected with one side beam, and the two connecting seats are arranged at an interval in the gauge direction of the bogie; a traction beam which is in a closed frame shape, the traction beam is connected between the two connecting seats in a horizontal mode, and a frame opening of the traction beam is parallel to the datum plane; wherein the reference surface is a coordinate surface determined by the movement direction and the gauge direction of the bogie; and thetwo ends of the traction beam are flexibly connected with the two connecting seats. According to the bogie of the invention, the technical problem that the bogie is poor in rail adaptability due to atraditional rigid integrated framework is solved. 本申请实施例中提供了一种转向架，包括：两个侧梁；两个连接座，一个所述连接座与一个所述侧梁连接，两个所述连接座沿所述转向架的轨距方向间隔设置；牵引梁，所述牵引梁为封闭的框形，所述牵引梁以平放的方式连接在两个所述连接座之间，所述牵引梁的框口平行于基准面；其中，所述基准面是所述转向架的运动方向和轨距方向确定的坐标面；所述牵引梁的两端和两个所述连接座之间的
