The invention discloses a double-motor stepless speed regulation electric drive axle, and relates to the field of machinery and vehicle transmission, the double-motor stepless speed regulation electric drive axle comprises a first drive motor, a second drive motor, a speed reducing mechanism and a differential mechanism, output shafts of the first drive motor and the second drive motor are on the same axis, and the speed reducing mechanism comprises a box body, a first planet row, a second planet row and a primary speed reducing gear; the first planet row, the second planet row and the first-stage reduction gear are arranged in the box body, the first driving motor is in driving connection with the first planet row, the second driving motor is in driving connection with the second planet row, the first planet row is in meshed connection with the second planet row, and the first planet row is in driving connection with the first-stage reduction gear. The primary reduction gear is in driving connection with the differential mechanism. The double-motor stepless speed change mechanism is compact in structure, small in size and capable of achieving stepless speed change through the double motors and the double planet rows.
