The invention discloses a dual-motor mechanical coupling electric drive axle and a vehicle, and relates to the technical field of axles. The dual-motor mechanical coupling electric drive axle comprises a first motor, a second motor, a first planetary reducer, a second planetary reducer and a reverse transmission mechanism. The first motor is connected with a first sun gear of the first planetary reducer and outputs torque through a first planet carrier of the first planetary reducer. The second planetary reducer and the first planetary reducer are coaxially arranged, and the second motor is connected with a second sun gear of the second planetary reducer and outputs torque through the second planetary reducer. A first gear ring of the first planetary reducer is in reverse transmission connection with the second planetary reducer through the reverse transmission mechanism. The dual-motor mechanical coupling electric drive axle and the vehicle have the advantages of being low in cost and high in reliability.
