The utility model discloses a can realize coaxial -type electric drive axle of self shifter, construct and differential mechanism including motor, planetary reducer, motor and planet gear connect, planetary reducer constructs and to connect with differential mechanism, and it still includes and be used for providing the actuating mechanism that shifts who shifts, the actuating mechanism that shifts is coaxial to be set up between planetary reducer structure and differential mechanism, planetary reducer constructs including one -level planet gear and second grade planet gear, and wherein the rotor of motor is connected with one -level planet gear, the one -level reduction gear is connected with second grade planet gear, and the second grade planet gear and the actuating mechanism that shifts are connected, the motor loops through one -level planet gear and second grade planet gear carry -over moment to differential mechanism as the power input, drives turning wheels through wheel hub. This device makes driving motor and vehicle driving situation have good matching, improves electric drive axle's efficiency, reduces the consumption of electric energy.
