Abstract: The present invention discloses a dual-motor coupling drive axle with a torque vectoring function. The dual-motor coupling drive axle includes: a main drive mechanism; a bevel gear differential; a TV control drive mechanism; a first single-row planetary gear train, of which a first sun gear is rotatably supported on a first half shaft and a first gear ring is connected with an output end of the TV control drive mechanism; a second single-row planetary gear train, of which a second gear ring is fixed to a drive axle housing and a second sun gear is coaxially and fixedly connected with the first sun gear; a third single-row planetary gear train.
