The invention provides a permanent magnet direct drive motor and axle box integrated rubber wheel drive structure which comprises a permanent magnet motor in the middle, walking wheels and an axle box. The permanent magnet motor comprises an external motor shell, a stator, an excitation coil and a motor shaft; the axle box comprises an axle box body and axle box end covers at the two ends of the axle box body, and the axle box body and the motor shell are fixedly connected into a whole. An integral bearing is arranged outside the axle box; a motor shaft is connected with a driving half shaft of the walking wheel; therefore, the motor volume is reduced without installing a gear box; the torque of the motor shaft is directly transmitted to the rubber tires for driving so that the transmission efficiency is improved, the weight and the size of the bogie are reduced, the curve passing performance of the bogie is improved, particularly the passing capacity of a small-radius curve is improved, and the structure is particularly suitable for urban rail transit which is limited by the land; in addition, the tire is a rubber tire so that the gradeability of the vehicle is also remarkably improved.

    本发明提供了一种采用永磁直驱电机与轴箱一体式的橡胶轮驱动机构,包括中部的永磁电机、走行轮、轴箱;永磁电机包括外部的电机壳、定子、励磁线圈、电机轴;轴箱包括轴箱体、轴箱体两端的轴箱端盖,轴箱体与电机壳固定连接成为一体;轴箱外部设有整体式轴承,电机轴与走行轮的驱动半轴相连,这样无需安装齿轮箱同时减小了电机体积,电机轴扭矩直接传递到橡胶轮胎上用于驱动,提高了传递效率,同时减小了转向架重量与体积,提升了转向架的曲线通过性能,尤其是小半径曲线的通过能力得到了提高,特别适合于城市轨道交通这种受到土地限制的情况;另外轮胎使用的是橡胶轮胎,车辆的爬坡能力也得到了显著的提高。
