The invention provides a direct-drive bogie. The direct-drive bogie comprises a framework, wheels, a traction motor, couplings and axle bridges, the traction motor is installed on the framework and provided with two driving ends, and the two driving ends are connected with the wheels through the couplings respectively; the outer sides, away from the couplings, of the two wheels on the same side of the transverse center line H are connected through the axle bridges, and the axle bridges are symmetrically arranged relative to the transverse center line H of the framework. A direct driving system is adopted, power only needs to be transmitted through the traction motor, the coupling, the axle bridge and the axle box body, traction force is prevented from passing through a gear box, the transmission efficiency is improved, purchase and maintenance of the gear box are also avoided, and the application and maintenance cost of the bogie is greatly reduced.

    本发明提供一种直驱转向架。所述直驱转向架包括构架、车轮、牵引电机、联轴节和轴桥,所述牵引电机安装在构架上,且所述牵引电机具有两个驱动端,两个所述驱动端分别通过联轴节与车轮连接;横向中心线H的同侧两个车轮远离联轴节的外侧通过所述轴桥相连,且所述轴桥相对于构架的横向中心线H对称设置。本发明采用直接驱动系统,动力仅需经过牵引电机、联轴节、轴桥、轴箱体传动,避免牵引力经过齿轮箱,提高传动效率,也避免对齿轮箱的采购和维护,大大降低转向架的运用维护成本。
