A road-rail vehicle according to the present invention comprises: a front track running unit which includes a pair of rail wheel units installed below a truck body frame spaced apart toward a commercial truck at a predetermined interval to move along railway rails, wherein the axles on which the pair of rail wheel units are mounted move up and down while rotating within a predetermined angular range according to the operation of a front lifting cylinder; a rear track running unit which includes two pairs of rail wheel units moving along the railway rails below the truck body frame of the commercial truck, wherein each of the axles of the two pairs of rail wheel units is axially mounted on a rear bogie frame supported by a rear lifting cylinder and a rear lifting guide link installed beneath the truck body frame of the commercial truck, the rear bogie frame moves up and down by being linked with the rear lifting guide link during the operation of the rear lifting cylinder, and a driving motor is installed on one side of each of the two pairs of rail wheel units; and commercial truck rotating means which allows the rotation of the rear track running unit so that the commercial truck positioned in the normal direction to the longitudinal direction of the railway rails aligns parallel to the longitudinal direction of the railway rails. Therefore, the road-rail vehicle can facilitate a turning process of the commercial truck.

    이 발명에 따른 도로 레일 겸용 차량은 상용 트럭의 전방으로 일정 간격 떨어진 트럭 차체 프레임의 하부에 철도 레일을 따라 이동하는 1조의 레일 바퀴 유닛이 설치되되 1조의 레일 바퀴 유닛이 축설된 차축은 전방 승하강 실린더의 작동에 따라 일정 각도 범위 내에서 회전 동작하면서 승하강 작동이 되는 전방 선로주행 유닛; 상용 트럭의 트럭 차체 프레임의 하부에 철도 레일을 따라 이동하는 2조의 레일 바퀴 유닛의 차축은 각각 상용 트럭의 트럭 차체 프레임 하부에 설치되는 후방 승하강 실린더와 후방 승하강 안내 링크에 의해 지지되는 후방 대차 프레임에 축설되고 후방 대차 프레임은 후방 승하강 실린더의 작동 시에 후방 승하강 안내 링크와 연계되어 승하강 작동이 되고 2조의 레일 바퀴 유닛의 일측에는 각각 주행용 모터가 설치된 후방 선로주행 유닛; 및 철도 레일의 길이방향에 대하여 법선방향으로 위치된 상태의 상용 트럭이 철도 레일의 길이방향에 나란해지도록 후방 선로주행 유닛의 회전을 허용하는 상용 트럭 회전수단; 을 포함하여 구성될 수 있다.
