The invention belongs to the technical field of electric drive axles, and particularly relates to a dual-motor dual-clutch multi-gear electric drive axle system which comprises a power input unit, a clutch unit and a transmission unit. The planetary gear train system is in transmission connection with the output end of the power input unit; the input end of the double-clutch speed change unit is in transmission connection with the output end of the planetary gear train system; the input end of the power output unit is in transmission connection with the output end of the double-clutch speed change unit; the planetary gear train system comprises a planet carrier and a planetary gear train, wherein one end of the planet carrier is in transmission connection with the output end of the power input unit; the planet wheel set is rotationally arranged at the other end of the planet carrier, the planet wheel set comprises two planet wheels which are coaxially and fixedly connected, one planet wheel is meshed with a fixed sun wheel which is fixedly connected to the axle housing, the other planet wheel is meshed with a non-fixed sun wheel which is fixedly connected to the axle housing, and the non-fixed sun wheel is fixedly connected to the axle housing. And the output end of the non-fixed sun gear is in transmission connection with the output end of the double-clutch speed change unit.
