The invention relates to a multi-gear duplex electric drive axle system and a vehicle, the multi-gear duplex electric drive axle system is suitable for a pure electric drive heavy commercial truck, and the system comprises a four-gear double-motor electric drive axle, a transmission drive axle, an inter-axle differential mechanism and a differential lock mechanism; the four-gear double-motor electric drive axle and the transmission drive axle are connected in series to form a double-linkage-axle structure. The inter-axle differential mechanism is arranged between the four-gear double-motor electric drive axle and the transmission drive axle, and the differential lock mechanism is used for locking or unlocking the inter-axle differential mechanism; when the differential lock mechanism is in a locking state, the four-gear double-motor electric drive axle and the transmission drive axle form an active-active four-wheel drive mode; when the differential lock mechanism is in an unlocking state, a rotating speed difference exists between the four-gear double-motor electric drive axle and the transmission drive axle.
本发明涉及一种多挡双联电驱桥系统及车辆,适用于纯电驱动的重型商用卡车,该系统包括四挡双电机电驱桥、传动驱动桥、轴间差速器、差速锁机构;四挡双电机电驱桥与传动驱动桥串联为双联桥结构;轴间差速器设置在四挡双电机电驱桥和传动驱动桥之间,差速锁机构用于锁止或解锁轴间差速器;当差速锁机构处于锁止状态时,四挡双电机电驱桥和传动驱动桥形成主动‑主动四轮驱动模式;当差速锁机构处于解锁状态时,四挡双电机电驱桥和传动驱动桥之间存在转速差。
