The present invention relates to an electric axle system for a commercial vehicle, comprising: a first clutch device which can be mounted between a motor and a differential case to enable or block power transmission; a second clutch device which is installed between the differential case and a disk; and an electromagnetic braking device which applies braking force to the disk, thereby minimizing the frequency of hub brake usage during the braking process. Furthermore, through control which disengages the first clutch device and the second clutch device during coasting, the present invention can block kinetic energy which was being transferred from the axle shaft to the motor, similar to the neutral gear state of a transmission. The present invention can extend an operating mileage, thereby improving fuel efficiency and enhancing the durability of the motor.

    본 발명은 모터와 디퍼런셜 케이스 사이에 동력 전달 또는 차단 가능하게 장착되는 제1클러치 장치와, 디퍼런셜 케이스와 디스크 간에 장착되는 제2클러치 장치와, 디스크에 제동력을 인가하는 전자기식 제동장치 등을 이용하여, 제동 과정에서 주브레이크 사용빈도를 최소화시킬 수 있고, 또한 타행 주행시 제1클러치 장치 및 제2클러치 장치를 결합 해제하는 제어를 통하여, 마치 변속기의 중립단 상태와 같이 액슬샤프트로부터 모터로 전달되던 운동에너지가 차단되도록 함으로써, 타행 주행거리를 늘려서 전비 향상 효과를 얻을 수 있고, 모터의 내구성을 향상시킬 수 있도록 한 상용차량용 전동화 액슬 시스템을 제공하고자 한 것이다.
