The invention belongs to the technical field of vehicle driving, and particularly relates to an electric drive assembly, a four-wheel drive system and a vehicle. The electric drive assembly comprises a first motor, a second motor, a first speed reducer, a second speed reducer, a first half shaft and a second half shaft; the output end of the first speed reducer is connected with the first half shaft, the input end of the second speed reducer is connected with the second motor, and the output end of the second speed reducer is connected with the second half shaft; the speed ratio of the first speed reducer is different from that of the second speed reducer; the rated rotating speed of the motor corresponding to the first speed reducer and the second speed reducer with the large intermediate speed ratio is higher, and the rated torque of the motor corresponding to the first speed reducer and the second speed reducer with the small intermediate speed ratio is higher.

    本申请属于车辆驱动技术领域,具体涉及一种电驱动总成、四驱系统及车辆,该电驱动总成包括第一电机、第二电机、第一减速器、第二减速器、第一半轴及第二半轴,所述第一减速器的输入端连接所述第一电机,所述第一减速器的输出端连接所述第一半轴,所述第二减速器的输入端连接所述第二电机,所述第二减速器的输出端连接所述第二半轴;所述第一减速器的速比与所述第二减速器的速比不同;所述第一减速器与所述第二减速器中速比较大的一个所对应的电机的额定转速更高,所述第一减速器与所述第二减速器中速比较小的一个所对应的电机的额定扭矩更高。
