The invention discloses an inter-wheel torque distribution electric drive axle which comprises a main drive motor, a main rotation speed reducer, a torque distribution motor, a planet row speed reducer, a torque distribution coupling mechanism, a differential mechanism, a left half shaft and a right half shaft. The main drive motor is connected with the input end of the main reducer; the torque distribution motor is connected with a sun gear of the planet row speed reducer; the torque distribution coupling mechanism is composed of a torque distribution planet row and a torque distribution cylindrical gear mechanism, a sun gear of the torque distribution planet row is connected with the output end of the planet row speed reducer, and a planet carrier of the torque distribution planet row is connected with the left half shaft. A gear ring of the torque distribution planet row is meshed with a torque distribution driving gear of the torque distribution cylindrical gear mechanism, and a torque distribution driven gear of the torque distribution cylindrical gear mechanism is connected with a second shaft of the main speed reducer. By controlling the output torque of the main drive motor and the torque distribution motor, the driving torque of the left and right wheels can be freely transferred and distributed, and the active safety and trafficability of the vehicle are remarkably improved.
