The invention relates to the technical field of electric drive axles, and discloses a novel electric drive axle of a pure electric tractor and an electric drive axle control method.The electric drive axle is characterized in that a first clutch is arranged between a first motor and a first high-gear gear set, and a second clutch is arranged between the first motor and a first low-gear gear set; a fourth clutch is arranged between the second motor and the second high-gear gear set, and a third clutch is arranged between the second motor and the second low-gear gear set; the first high-gear gear set, the first low-gear gear set, the second high-gear gear set and the second low-gear gear set are in transmission connection with the central differential mechanism; the central differential mechanism is in transmission connection with the first wheel through the first half shaft and the first final transmission mechanism, and the central differential mechanism is in transmission connection with the second wheel through the second half shaft and the second final transmission mechanism. The double motors are symmetrically arranged, the structure is compact, a high gear and a low gear are arranged, and the operation and transfer requirements can be met; centralized driving and distributed driving are achieved, and the use performance of the electric drive axle is improved.

    本发明涉及电驱桥技术领域,公开一种纯电动拖拉机新型电驱桥及电驱桥控制方法,该电驱桥包括:第一电机与第一高挡齿轮组间设置第一离合器,第一电机与第一低挡齿轮组间设置第二离合器;第二电机与第二高挡齿轮组间设置第四离合器,第二电机与第二低挡齿轮组间设置第三离合器;第一高挡齿轮组、第一低挡齿轮组、第二高挡齿轮组和第二低挡齿轮组与中央差速器传动连接;中央差速器通过第一半轴并经过第一最终传动机构与第一车轮传动连接,中央差速器通过第二半轴并经过第二最终传动机构与第二车轮传动连接。本发明采用双电机对称布置,结构紧凑,具有高低两个挡位,能满足作业和转运需求;实现集中式驱动与分布式驱动,提高了电驱桥的使用性能。
