The invention relates to the technical field of electric drive axles, and discloses a novel electric drive axle of a pure electric tractor and an electric drive axle control method.The electric drive axle is characterized in that a first clutch is arranged between a first motor and a first high-gear gear set, and a second clutch is arranged between the first motor and a first low-gear gear set; a fourth clutch is arranged between the second motor and the second high-gear gear set, and a third clutch is arranged between the second motor and the second low-gear gear set; the first high-gear gear set, the first low-gear gear set, the second high-gear gear set and the second low-gear gear set are in transmission connection with the central differential mechanism; the central differential mechanism is in transmission connection with the first wheel through the first half shaft and the first final transmission mechanism, and the central differential mechanism is in transmission connection with the second wheel through the second half shaft and the second final transmission mechanism. The double motors are symmetrically arranged, the structure is compact, a high gear and a low gear are arranged, and the operation and transfer requirements can be met; centralized driving and distributed driving are achieved, and the use performance of the electric drive axle is improved.
