The invention relates to the technical field of locomotives, in particular to a bogie and a large-axle-load locomotive. The bogie comprises a framework, a driving device, a wheel pair and a traction device, the framework comprises a box girder frame structure, and the box girder frame structure comprises a traction beam; the driving device comprises a direct-drive motor, a first suspension structure, a second suspension structure and a third suspension structure, one end of the first suspension structure and one end of the second suspension structure are both connected to one side of a shell of the direct-drive motor, one end of the third suspension structure is connected to the other side of the shell of the direct-drive motor, and the wheel pair comprises an axle and wheels. The axle is connected with the direct drive motor; the traction device comprises a traction rod, one end of the traction rod is installed on the traction beam, the other end of the traction rod is connected with the locomotive body, and the traction rod and the horizontal plane are arranged in an included angle mode so that the vertical distance between the intersection point of the extension line of the traction rod and the center line of the framework and the rail face can be reduced, and the purpose of smaller axle load transfer of the whole locomotive is achieved. And the operation safety of the locomotive is higher.

    本公开涉及机车技术领域,尤其是涉及一种转向架及大轴重机车。转向架包括构架、驱动装置、轮对和牵引装置,构架包括箱梁框体结构,箱梁框体结构包括牵引梁;驱动装置包括直驱电机、第一悬挂结构、第二悬挂结构和第三悬挂结构,第一悬挂结构的一端和第二悬挂结构的一端均连接于直驱电机外壳的一侧,第三悬挂结构的一端连接于直驱电机外壳的另一侧,轮对包括车轴和车轮,车轴与直驱电机连接;牵引装置包括牵引杆,牵引杆的一端安装于牵引梁,另一端与车体连接,牵引杆与水平面呈夹角设置,以降低牵引杆的延长线与构架的中心线的交点与轨道面之间的垂直距离,达到整车轴重转移更小的目的,适用于大轴重机车,且机车运行安全性更高。
