Abstract
An electric drive axle comprises: a housing; a drive motor having an output shaft for outputting torque; a main reducer configured to perform two-stage reduction to amplify the torque outputted from the output shaft; a differential including a differential housing, a planetary gear shaft, a left and right drive shafts rotating about an axis of rotation; a torque vectoring motor; a double row planetary gear reduction mechanism configured to amplify power outputted from the torque vectoring motor; a double row planetary gear torque vectoring mechanism connected to the double row planetary gear reduction mechanism and configure to receive torque outputted from the double row planetary gear reduction mechanism and output reverse torque in contrast to the torque received; and a single row double planetary gear coupling mechanism providing opposite direction torques to the left and right drive shafts respectively.
