The invention discloses a single-motor torque vector planet row speed reducer which comprises a motor and speed reducer parts symmetrically arranged on the two sides of the motor. The speed reducer part comprises a speed reducer shell, a planetary gear transmission mechanism and a clutch, the planetary gear transmission mechanism comprises a first-stage driving sun gear, a duplex planet gear, a gear ring and a planet carrier, the output end of the motor is connected with the first-stage driving sun gear through a spline, and the first-stage driving sun gear is in meshing transmission with the duplex planet gear; the duplex planet wheel is in meshing transmission with the gear ring, the clutch is connected between the gear ring and the speed reducer shell, the duplex planet wheel is connected with the planet carrier through the planet gear pin, and finally torque is output to the wheel end. Vector control of the speed reducer is achieved through one motor, meanwhile, high integration is achieved, and the axial arrangement space is shortened.
