The present invention provides an electric driving unit for a commercial vehicle, which constitutes a plurality of driving motors mounted inside a motor housing in a circumferential direction, a main reduction unit composed of an output gear of each driving motor and a driving gear engaged with the output gear to transmit power to an axle shaft, and an axle housing covering the main reduction unit and coupled to the motor housing in a single modularized structure to realize common use of an electrified axle assembly for each vehicle type and selectively operate the plurality of driving motors to reduce and control motor torque outputted to the axle shaft, thereby controlling the motor torque and realizing torque vectoring according to a driving condition.

    본 발명은 모터 하우징 내에 원주방향을 따라 장착되는 복수개의 구동모터와, 각 구동모터의 출력기어 및 이와 맞물려 액슬샤프트로 동력을 전달하는 구동기어로 구성되는 메인 감속부와, 메인 감속부를 커버하며 모터 하우징과 결합되는 액슬 하우징 등을 하나의 모듈화된 구조로 구성하여, 차종별로 전동화 액슬어셈블리의 공용화를 실현할 수 있고, 또한 복수개의 구동모터를 선택적으로 구동시켜 액슬샤프트로 출력되는 모터 토크를 가감 조절할 수 있도록 함으로써, 주행 조건에 따른 모터 토크 조절 및 토크 벡터링 구현이 가능하도록 한 상용차량용 전동식 구동 유닛을 제공하고자 한 것이다.
