The invention provides a permanent magnet motor and axle box integrated driving structure. The integrated driving structure comprises a permanent magnet traction motor and an axle box, an axle, namelya motor output shaft, serves as a rotor, a wheel set is pressed on the motor output shaft and directly serves as the axle to transmit torque to the wheel set, and an axle box body and a permanent magnet traction motor shell are fixedly connected into a whole. The permanent magnet motor directly drives the wheel set, so a gear box, a coupling and other complex transmission structures are omitted,the overall structure of a bogie can be simplified, the fixed axle distance is shortened, operation noise is lowered, the self weight of the bogie is reduced, the reliability is improved, the transmission efficiency of the driving structure is greatly improved, and maintenance cost is saved. The axle box structure is simplified to the maximum extent on the premise that the function can be completely guaranteed, and great help is provided for earlier-stage installation and later-stage maintenance.

    本发明提供一种永磁电机与轴箱一体式驱动结构,包括永磁牵引电机和轴箱,车轴即电机输出轴作为转子,电机输出轴上压装轮对,直接作为车轴将转矩传递给轮对,轴箱体与永磁牵引电机外壳固定连接成为一体;本发明永磁电机直接驱动轮对,省去了齿轮箱、联轴节等复杂的传动结构,可以使转向架整体结构简化、缩短固定轴距、降低运行噪声、减轻转向架自重、提高可靠性、大大提高驱动装置的传动效率以及节省保养维护的费用;在能够完全保证功能的前提下最大化简化了轴箱结构,对前期的安装及后期的维护都有极大的帮助。
