The invention aims to provide a permanent-magnet direct-drive combined axle for a railway self-walking torpedo car, which comprises an axle, a motor connecting hollow shaft is arranged on the outer side of the axle in an interference manner, the motor connecting hollow shaft comprises a supporting part, first transition parts are arranged on two sides of the supporting part, a second transition part is arranged on one side of the two first transition parts, and a permanent-magnet direct-drive combined type axle is arranged on the other side of the two first transition parts. A third transition part is arranged on one side of the two second transition parts, and a fourth transition part is arranged on one side of the third transition part. On the basis of not changing the structure of the permanent magnet motor of the existing torpedo car, the permanent magnet direct drive combined axle for the railway self-walking torpedo car with the same structural interface as the existing axle is used for replacing the original axle, the axle stress structure is optimized, self-powered running of the torpedo car is realized, the application efficiency of the torpedo car is improved, and the application cost is reduced.

    本发明的目的在于提供一种铁路自走行混铁车用永磁直驱驱动组合式车轴,包括车轴,车轴的外侧过盈设置有电机连接空心轴,电机连接空心轴包括支撑部,支撑部的两侧设置有过渡部一,两个过渡部一的一侧设置有过渡部二,两个过渡部二的一侧设置有过渡部三,过渡部三的一侧设置有过渡部四;本发明在不改变既有混铁车永磁电机的结构基础上,利用与既有车轴结构接口相同的铁路自走行混铁车用永磁直驱驱动组合式车轴替换原车轴,优化车轴受力结构,实现混铁车自带动力行驶,提高混铁车运用效率、降低运用成本。
