The invention provides an electric drive axle transmission system and a vehicle, and the electric drive axle transmission system comprises a first motor, a second motor, a gear shifting assembly, an output shaft, a first transmission shaft assembly, a second transmission shaft assembly, a third transmission shaft assembly, a fourth transmission shaft assembly, a hub reduction gear assembly and wheels, the first transmission shaft assembly and the second transmission shaft assembly are sequentially connected between the first motor and the gear shifting assembly, the third transmission shaft assembly and the fourth transmission shaft assembly are sequentially connected between the second motor and the gear shifting assembly, and the gear shifting assembly comprises a planetary reducer, a differential mechanism and a plurality of gear meshing pieces. The planetary reducer can be in transmission connection with different gear meshing pieces so as to adjust the output transmission ratio of the planetary reducer. The differential mechanism is connected with the planetary reducer, the output shaft is connected with the differential mechanism, and the hub reduction gear assembly is connected between the output shaft and the wheels, so that the middle structure of the electric drive axle transmission system is simplified, and the space occupied by the multi-stage transmission structure is reduced.
