According to the present invention, an apparatus for reducing drag torque of a four-wheel drive vehicle is provided. A first flow passage connected to a groove of a drum outer circumference unit of a drum, and a second flow passage and a third flow passage branched from the first flow passage to supply churned oil to a bearing and a clutch pack when the drum is rotated, are formed inside a housing of a sub-transmission. A solenoid valve controlling the flow passage is installed in a portion where the first flow passage is branched. Accordingly, the present invention reduces drag torque to prevent degradation of fuel efficiency caused by a power loss.

    본 발명에 따르면, 부변속기 하우징 내부에는, 드럼 외경부의 그루브와 연통하는 제1유로와, 상기 제1유로로부터 분기되어 드럼 회전시 처닝된 오일을 베어링과 클러치팩으로 각각 공급하기 위한 제2,3유로가 형성되며, 상기 제1유로가 분기되는 부분에는, 유로를 제어하는 솔레노이드밸브가 설치된 4륜 구동차량의 드래그 토크 저감장치가 제공된다. 이에 의하면, 드래그 토크를 저감하여 동력손실로 인한 차량 연비가 악화되는 것을 방지할 수 있다.
