The coaxial double-planet-row type double-motor electric drive axle comprises a first drive motor, a second drive motor, a double-planet-row speed reducing mechanism and a differential mechanism which are coaxially arranged, the double-planet-row speed reducing mechanism comprises a first planet row and a second planet row, the first drive motor is in transmission connection with the first planet row, and the second drive motor is in transmission connection with the second planet row. A first planet carrier of the first planet row and the second driving motor are in transmission connection with the second planet row, a second planet carrier of the second planet row is in transmission connection with the differential mechanism, and the differential mechanism is connected with a first wheel through a first output half shaft and connected with a second wheel through a second output half shaft. The coaxial double-planet-row type double-motor electric drive axle is compact in structure and small in occupied space, and the cost is reduced.
