The invention discloses a dual-motor coupling driving system and a new energy electric vehicle. The dual-motor coupling driving system comprises a main driving motor, an auxiliary driving motor and ahydraulic torque converter, wherein the main driving motor comprises a first rotating shaft, two ends of the first rotating shaft form a front shaft extension end and a rear shaft extension end, the front shaft extension end is used for being connected with a load, the auxiliary driving motor comprises a second front shaft extension end, and the hydraulic torque converter is used for connecting the second front shaft extension end of the auxiliary driving motor with the rear shaft extension end of the main driving motor. The dual-motor coupling driving system is advantaged in that under normalconditions, a load is driven by the main driving motor, when the output torque of the main driving motor is insufficient, the auxiliary driving motor is coupled and transmitted to the main driving motor through the hydraulic torque converter, the torque of the auxiliary driving motor is transmitted to the main driving motor, so the torque of the main driving motor and the torque of the auxiliarydriving motor are superposed, and the torque output of the whole driving system is met, the dual-motor coupling driving system is simple in structure, the auxiliary driving motor and the main drivingmotor are coupled through the hydraulic torque converter, reliability is high, and noise is low.
