The present invention relates to a wing body for a cargo vehicle, which comprises: a large number of wing support frames arranged apart from each other on the upper side of a loading box of the cargo vehicle; base plates respectively installed on the upper end unit of each wing support frame, and extended in the widthwise direction of the loading box, and providing supporting power; main hinge units respectively located in the center unit of the base plates; a pair of rotation bars rotatably linked to the main hinge units, and extended in a longitudinal direction, and capable of performing independent rotation; a wing opening/closing apparatus having a hydraulic actuator rotating each rotating bar; and a pair of wings fixed on each rotation bar and opened/closed in accordance with the rotation of the rotating bars. Since the center fixing beam installed on the upper end unit of the wing body is omitted, the weight and center of gravity of the wing body can be lowered, thereby improving the driving safety of a cargo vehicle. In addition, the fuel efficiency of the vehicle can be improved by the reduced weight of the wing body.
본 발명은 화물차량용 윙바디에 관한 것으로서, 화물차량의 적재함 상부에 상호 이격 배치되는 다수의 윙지지프레임, 각 윙지지프레임의 상단부에 설치되는 것으로서, 적재함의 폭방향으로 연장되며 지지력을 제공하는 베이스플레이트와, 베이스플레이트의 중앙부에 위치하는 메인힌지부와, 메인힌지부에 회동 가능하도록 링크되며 길이방향으로 연장되고 독립적 회동운동이 가능한 한 쌍의 회동바와, 각 회동바를 회동운동 시키는 유압액츄에이터를 구비한 윙개폐장치 및 각 회동바에 고정되어 회동바의 회동운동에 따라 개폐되는 한 쌍의 윙을 포함하는 것을 특징으로 하며, 윙바디의 상단부에 설치되는 센터고정빔을 생략하여, 윙바디의 중량 및 무게 중심을 낮춤으로써 화물차량의 주행 안전성을 향상시킴은 물론 윙바디의 중량이 감소된 만큼 차량의 연비를 개선시키는 효과를 제공한다.
