The invention discloses a double-motor electric drive axle system and a vehicle. According to the double-motor electric drive axle system, two drive mechanisms are in transmission connection with two wheels correspondingly; the motor is in transmission connection with the wheels through a transmission mechanism; the transmission mechanism comprises a first driving gear, a second driving gear, a first driven gear, a second driven gear, a transmission shaft and a third driving gear, wherein the second driving gear and the first driving gear are distributed in a spaced mode, the first driven gear is meshed with the first driving gear, the second driven gear is meshed with the second driving gear, the transmission shaft rotationally penetrates through the first driven gear and the second driven gear, and the third driving gear is fixedly arranged on the transmission shaft. The third driven gear is meshed with the third driving gear, the third driven gear is fixedly connected with the wheels, one linkage assembly can lock or unlock the relative position of the first driven gear and the transmission shaft, and the other linkage assembly can lock or unlock the relative position of the second driven gear and the transmission shaft. The synchronous gear shifting function of two wheels, the differential control function of the two wheels and the slip limiting function can be achieved.
