The invention relates to the technical field of power drive systems, and provides a double-motor electric drive axle and a vehicle. The output end of a first motor is connected with a first input shaft, and a first-gear gear pair and a second-gear gear pair are fixed to the first input shaft in the axial direction of the first input shaft; the first intermediate shaft can be selectively in transmission connection with the first-gear gear pair or the second-gear gear pair through a gear shifting mechanism, and the first secondary gear pair is connected with the first intermediate shaft and the first output shaft; the second motor is in transmission connection with the differential through a second transmission assembly; a gear ring of the planet gear speed reducer is fixed to the axle housing, the first output shaft is connected with the sun gear, the first planet gear is clamped between the sun gear and the gear ring in the radial direction, and the first planet gear is connected with a shell of the differential mechanism through a planet carrier. Therefore, power of the two motors is converged at the differential mechanism, large-torque output can be achieved through optimized matching of the torque of the motors and the transmission speed ratio, and the two motors can fully work in a high-efficiency area under the common working condition.
