The invention relates to an electric drive axle assembly, a gear shifting method and an electric drive axle working method. The electric drive axle assembly is used for converting electric energy into mechanical energy and driving a vehicle to advance and comprises a driving motor assembly and at least one driving motor, the driving motor is matched with a speed reducer, and the speed reducer achieves multi-stage speed reduction through cooperation of a planet row and a cylindrical gear so as to cover the working condition requirement of the whole vehicle; the gear shifting assembly comprises a gear shifting tooth holder and a gear shifting tooth sleeve; the differential mechanism assembly comprises a differential mechanism and is used for distributing torque; the power output assembly comprises half shafts located on the two sides of the differential mechanism, and power is transmitted to wheels through the differential mechanism and the half shafts. According to the electric drive axle assembly, the driving motor assembly is matched with the gear shifting assembly, and the planet row is matched with the cylindrical gear to transmit power, so that switching of different gears is achieved, and different working condition requirements of a vehicle are met.
