Beschreibung
Zusammenfassung:	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 di
