The invention provides a permanent magnet motor direct drive large axle load walking device, which comprises a large swing bolster, a frame and a non-power bogie and further comprises a power bogie; the power bogie comprises a permanent magnet motor, wheels and a steel structure frame, the permanent magnet motor is arranged between the two wheels, and an output shaft of the permanent magnet motor serves as a wheel axle. The permanent magnet motor is connected with the steel structure frame in a flexible suspension mode. The permanent magnet motor is directly mounted on the axle, so that the problem that a traditional transmission mode of a motor and a speed reducer cannot be adopted due to the fact that the internal space of the running gear of the large-axle-load self-running metallurgical transport vehicle is limited is solved. In addition, the direct driving mode of the permanent magnet motor enables a mechanical transmission part to be simpler and more efficient, the universality is improved, and the failure rate is reduced. According to the invention, a single vehicle can carry out self-transportation operation; therefore, the problem of low operation efficiency caused by traction alignment and vehicle marshalling operation of an internal combustion locomotive is solved, the transportation efficiency is improved, and the effect of "one tank for complete process" is achieved.
本发明提供了一种永磁电机直接驱动大轴重走行装置,包括大摇枕、车架、非动力转向架,还包括动力转向架,动力转向架包括永磁电机、车轮、钢结构架,永磁电机在两个车轮之间,永磁电机的输出轴作为车轮轴,永磁电机通过柔性悬挂的方式与钢结构架连接。本发明采用永磁电机直接安装在车轴上的方式,解决了大轴重自运行冶金运输车辆走行部内部空间有限,无法采用传统的电机+减速机的传动方式的难题,而且永磁电机直接驱动的方式使得机械传动部分更加简洁高效,提高了通用性,降低了故障率。本发明使得单车能够自行运输作业,摆脱了内燃机车牵引对位、车辆编组作业带来的运转效率低下的问题,提高了运输效率,实现了“一罐到底”。
