The invention provides a four-gear variable-speed axle power transmission system of a pure electric mining truck, which comprises a driving motor, a first-stage speed reducer, a transmission, an output speed reducer and a differential mechanism, and the transmission adopts a transmission structure consisting of three parallel shafts, four gear pair mechanisms and two gear shifting executing mechanisms to realize multi-stage four-gear speed change. The defects that in the prior art, a transmission route is long, transmission efficiency is low, the size is large, and arrangement is difficult can be overcome.

    本发明提供一种纯电动矿用卡车四档变速桥动力传动系统,包括驱动电机、一级减速器、变速器、输出减速器和差速器,其中变速器采用由三根平行轴、四套齿轮副机构和两套换档执行机构组成的传动结构实现了多级四档变速。能够克服现有技术中传动路线较长、传动效率低且体积大、布置困难的缺陷。
