The invention provides an electric driving system, engineering machinery and an electric driving system control method, the electric driving system comprises a main driving motor, an auxiliary driving motor, a gearbox assembly and an axle, and the gearbox assembly comprises a first input shaft, a second input shaft, an output shaft, a first speed reducing mechanism, a second speed reducing mechanism and a clutch mechanism. Wherein the main driving motor, the first input shaft, the first speed reducing mechanism and the output shaft are sequentially in transmission connection, the auxiliary driving motor, the second input shaft, the second speed reducing mechanism and the output shaft are sequentially in transmission connection, and the clutch mechanism is arranged between the auxiliary driving motor and the output shaft so as to connect or interrupt power transmission between the auxiliary driving motor and the output shaft. The output shaft is in transmission connection with the axle. The electric drive system can meet the walking and operation requirements of engineering machinery such as an electric loader, a high-torque and high-rotating-speed motor does not need to be used, the cost can be reduced, and power interruption is avoided during gear shifting.

    本发明提供了一种电驱动系统、工程机械及电驱动系统控制方法,电驱动系统包括主驱动电机、辅助驱动电机、变速箱总成和车桥,变速箱总成包括第一输入轴、第二输入轴、输出轴、第一减速机构、第二减速机构和离合机构。其中,主驱动电机、第一输入轴、第一减速机构和输出轴依次传动连接,辅助驱动电机、第二输入轴、第二减速机构和输出轴依次传动连接,离合机构设置在辅助驱动电机和输出轴之间,以连通或中断辅助驱动电机和输出轴之间的动力传递,输出轴和车桥传动连接。以上电驱动系统能够满足电动装载机之类的工程机械的行走和作业需求,无需使用高扭矩、高转速的电机,可以降低成本,且在换挡时避免出现动力中断。
