The invention discloses a loader structure with independently-driven front and rear axles and a dynamic torque distributing method. The loader structure comprises an engine, a generator, a rectifier, a super capacitor, three driving motors, a hydraulic pump, a working device, a front drive axle, a rear drive axle, two front wheels, two rear wheels, a vehicle control unit, an engine controller, a super-capacitor, controllers of the three driving motors, a hydraulic pump controller, sensors of four wheels, a front drive axle sensor, a rear drive axle sensor and command codes. The method comprises the following steps: acquiring the command codes and the vehicle running state parameters; processing and calculating the acquired data; performing corresponding control strategies to control the vehicle according to the processed data; sending torque control command codes to corresponding driving motors according to the control strategies. With the adoption of the method, the torque of the front and rear axles can be reasonably distributed according to the variation of the loads of the front and rear axles, so that the energy utilization rate of the whole vehicle can be improved; meanwhile, the dynamic performance of the vehicle in an extreme working condition can be improved through the system, and the advantages of independent drive can be brought into full play.
