The invention provides an electric drive axle system and a working method thereof, relates to the field of electric drive axles, and adopts the scheme that an auxiliary shaft and a half shaft I are arranged in parallel, a clutch I, a clutch II, a clutch III and a clutch IV are sequentially arranged on the auxiliary shaft in the direction from the half shaft I to the half shaft II, a gear shifting mechanism I is arranged on the half shaft I, and a gear shifting mechanism II is arranged on the half shaft II; a first gear shifting mechanism is arranged on the first half shaft, a second gear shifting mechanism is arranged on the second half shaft, the first motor can drive the first half shaft to rotate through the first gear shifting mechanism, the first motor can further drive the auxiliary shaft to rotate, the second motor can drive the second half shaft to rotate through the second gear shifting mechanism, the second motor can further drive the auxiliary shaft to rotate, and the auxiliary shaft can transmit power of the first motor to the first half shaft through the first clutch. The auxiliary shaft can transmit power of the second motor to the differential mechanism through the second clutch and the third clutch, and the auxiliary shaft can transmit power of the second motor to the second half shaft through the fourth clutch. According to the invention, the economical efficiency of the whole vehicle can be effectively improved, and the problem of tire grinding and tire eating under complex road conditions can be solved.

    本发明提供了一种电驱桥系统及其工作方法,涉及电驱桥领域,采用的方案是:副轴与半轴一平行设置,沿半轴一到半轴二的方向,副轴上依次设置有离合器一、离合器二、离合器三和离合器四,半轴一上设置有换挡机构一,半轴二上设置有换挡机构二,电机一通过换挡机构一能够驱动半轴一转动,电机一还能驱动副轴转动,电机二通过换挡机构二能够驱动半轴二转动,电机二还能驱动副轴转动,副轴能够通过离合器一将电机一的动力传递至半轴一,副轴能够通过离合器二和离合器三将电机二的动力传递给差速器,副轴能够通过离合器四将电机二的动力传递至半轴二。本发明能够有效提高整车经济性同时,还能解决复杂路况下磨胎吃胎问题。
