The invention provides a hydraulic auxiliary drive system by adopting wheel hub motors and solves the problems that a traditional rear drive vehicle cannot meet power performance requirements on low-adhesion coefficient road surfaces and large-slope road surfaces, and the existing wheel hub motor hydraulic drive system cannot meet the requirement for high flow of wheel hub motors. The system comprises a hydraulic pump assembly, a control valve bank, a controller, a power take-off device, a power take-off device output shaft, a left front wheel, a left wheel hub motor, a right wheel hub motor, a right front wheel and a fuel tank. Reversing valves in the control valve bank are connected through a pipeline; the reversing valves in the control valve bank are connected with the controller through an electric circuit. According to the invention, a hydraulic pump is driven by the power take-off device, the working positions of the control valve bank are switched by the controller, thus multiple work modes are formed, and control fuel of hydraulically operated reversing valves is controlled by solenoid reversing valves, to control the work states of the wheel hub motors. Reliable work of the system can be guaranteed through the control valve bank, so that the requirement for the high flow of the wheel hub motors is met.
