The invention provides a full-hydraulic four-wheel independent drive system and an electric wheel loader. The full-hydraulic four-wheel independent drive system comprises a control unit VCU, a right front wheel, a right rear wheel, a left rear wheel and a left front wheel drive axle structure assembly, wherein the right front wheel, the right rear wheel, the left rear wheel and the left front wheel drive axle structure assembly are arranged on a frame; the drive axle structure assembly comprises a four-quadrant hydraulic pump motor and a drive axle which is connected with the four-quadrant hydraulic pump motor and transmits power to wheels, the rotating speed of each wheel is controlled by controlling the hydraulic valve group to output different hydraulic energy and controlling different displacements of the four-quadrant hydraulic pump motor, and the differential speed and the torque between the wheels are guaranteed; therefore, the phenomenon of parasitic power and energy loss caused by slipping during normal running and operation of the vehicle is avoided; by utilizing the four-quadrant working characteristics of the four-quadrant hydraulic pump motor and the hydraulic energy accumulator, the kinetic energy generated during braking of the system can be recycled and stored to be reused.

    本发明提供了一种全液压四轮独立驱动系统及电动轮式装载机,全液压四轮独立驱动系统包括控制单元VCU、设置于车架上的右前轮、右后轮、左后轮以及左前轮驱动桥结构总成;驱动桥结构总成包括有四象限液压泵马达,以及与四象限液压泵马达连接为车轮传递动力的驱动桥,通过控制液压阀组输出不同的液压能和控制四象限液压泵马达的不同排量来控制各个车轮的转速,保证各个车轮之间的差速和转矩,进而确保车辆正常行驶和作业时不存在打滑导致出现寄生功率,造成能量损失;利用四象限液压泵马达四象限工作特性以及液压储能器,能够回收系统制动时的动能,将其存储起来以实现再次利用。
