Description

WING BODY FOR TRUCK WITH IMPROVED WATER LEAKAGE PREVENTING STRUCTURE}

The present invention relates to a wing body installed in a freight vehicle, and more particularly, to a wing body having an improved leak-proof structure that can prevent rain water from leaking into the cargo loading space.

The cargo box of the cargo vehicle can be opened to both sides and the rear wall to facilitate the loading and unloading of cargo. However, the stacker of such a structure can not protect the cargo to be loaded from snow and rain, and has a problem such that the cargo falls out of the stack during transportation, so the preference of the so-called box vehicle that can seal the cargo box from the outside completely increases. .

The box vehicles known so far are known to have a cabinet type that opens to the rear side and a wing body type that opens to both sides. A cargo vehicle with wing bodies is used to improve productivity in the logistics area due to shortening of loading and unloading of cargo. It is contributing greatly and is being used rapidly.

As shown in FIG. 12, the wing body 100 of a conventionally known freight vehicle includes an iron plate 106 galvanized on the outside of a body frame by two wings 102 and 104 installed to be openable and open to both sides of a loading box. These wings (102, 104) are hinged to be rotatable relative to a longitudinal beam (108) installed in the longitudinal direction of the vehicle. In this case, the longitudinal beam 108 is fixed to the front and rear transverse beams 110 respectively installed on the front side and the rear side of the loading box. In addition, the hinge fixing portion in which both wings 102 and 104 are hinged is provided with a cover 112 for preventing rainwater penetration into the loading space and corrosion due to rainwater, and each wing hinged to the longitudinal beam 108. 102 and 104 are opened and closed by two hydraulic cylinders 114 and 116 respectively installed on the front side and the rear side of the loading box.

However, the cover 112 is due to the nature of the wing body can not only use a flexible tarpaulin (Tarpaulin) material, such as a tent, this part when the cover 112 is peeled off or damaged due to frequent opening and closing operations of both wings (102,104) Rainwater soaks through the cargo through the rain, or the rainwater is left in the cover 112, causing many problems, such as corroding the hinge structure.

In addition, the longitudinal beams 108, on which the wings 102 and 104 are installed, are generally made of a rectangular beam having a hollow rectangular cross-sectional shape, and since only the both ends thereof are fixed to the transverse beam 110, the wing body 100 having the above-described configuration is 5 When applied to a large cargo vehicle of more than one ton, the longitudinal beam of the longitudinal beam 108, as shown in the imaginary line, sags toward the loading space, and this phenomenon causes the longitudinal beam to vibrate violently when driving on a bad road. , The hinges are damaged and the durability is greatly reduced.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wing body for a cargo vehicle having an improved leakage preventing structure that prevents rainwater from penetrating and furthermore, corrosion by rainwater is not caused.

Another object of the present invention is to provide a wing body for a freight vehicle that can prevent degradation of durability due to deflection of the longitudinal beam by reinforcing the longitudinal beam strength.

In order to achieve the above object, the present invention, a cargo vehicle including a longitudinal beam installed in the longitudinal direction of the vehicle at the intermediate position in the vehicle width direction, and a wing that is hinged to the longitudinal beam rotatably to open and close the side of the loading box. In the wing body of, the longitudinal beam is formed by the rain gutter channel portion, and is achieved by the wing body having a leakage preventing structure provided with a sealing material for preventing leakage between the longitudinal beam and the wing. In this case, the longitudinal beam may be formed in various shapes for strength reinforcement.
