The invention discloses a multi-mode torque directional distribution electric drive axle with a single actuator. The multi-mode torque directional distribution electric drive axle comprises a main motor, an auxiliary motor, a differential mechanism, a left half shaft, a right half shaft, a main speed reducer, an auxiliary speed reducer, a third planet row, a duplicate gear mechanism, a three-phase actuator and the like. The main motor and the auxiliary motor are respectively connected with the input ends of the main reducer and the auxiliary reducer; the output ends of the main reducer and the auxiliary reducer are respectively connected with a differential shell and the input end of the third planet row; two output ends of the third planet row are respectively connected with the three-phase actuator and the duplicate gear mechanism; the output end of the duplicate gear mechanism is connected with the differential mechanism shell. The three-phase actuator is a synchronous gear shifting mechanism, and when the three-phase actuator works at the left position, the middle position and the right position, locking of the third planet row, decoupling of the third planet row and connection of the third planet row and the left half shaft can be achieved. By controlling the three-phase actuator, three driving modes of main motor independent driving, dual-motor torque coupling driving and torque directional distribution can be realized.
