The invention discloses a dual-motor variable speed driving device for an electric loader, and belongs to the technical field of electric loader driving. Comprising a driving motor and a working motor which are simultaneously connected with a gearbox, the gearbox is provided with a seventh gear connected with a driving shaft of the working motor, and an output shaft of the gearbox is respectively connected with a working pump and engineering machinery. According to the driving device, the driving motor and the working motor are connected with the same gearbox to be integrally arranged, power can be provided for a whole vehicle hydraulic system through the working pump, walking power output is provided for engineering machinery through the output shaft, and compared with traditional separate arrangement of the driving motor and the working motor, more space and cost are saved; and transmission can be better conducted through the gearbox, different requirements are met through different transmission ratios, efficiency is improved, and energy consumption is reduced.

    本发明的一种电动装载机用双电机变速驱动装置,属于电动装载机驱动技术领域。包括同时连接变速箱的驱动电机和工作电机,变速箱设有齿轮七与工作电机的驱动轴连接,变速箱的输出轴分别连接有工作泵和工程机械。驱动装置将驱动电机和工作电机连接同一个变速箱进行集成布置,且可以通过工作泵给整车液压系统提供动力,通过输出轴给工程机械提供行走动力输出,相对于传统的驱动电机和工作电机分开布置更加节约空间和成本,且通过变速箱可以更好的进行传动,通过不同的传动比满足不同需求,提升效率和降低能耗。
