As shown in FIG. 1, a wing -body-integrated trailer according to an embodiment of the present invention includes a towing device 10 and a cargo container 20. The towing device 10 is a part configured to be towed by being coupled with a towing vehicle (not shown). To this end, the towing device 10 comprises a fastening for engaging the towing vehicle. In one embodiment of the present invention, the towing device 10 is provided with a landing gear (not shown) so that when the wing-bodied trailer according to the embodiment of the present invention is parked without being pulled by the towing vehicle, It can be fixed so as to be parked at a height.

The cargo container 20 is provided with a traveling portion 21 which is towed by the towing device 10 and enables traveling or braking on the road. For example, the driving unit 21 may be composed of one or more wheels. The running section 21 can be connected to a driving device necessary for traveling on the road, such as a power transmission device, a braking device, and a lighting device for a brake light or a turn signal lamp.

The cargo container 20 includes a lower frame 22 and a receiving portion 23. A loading space is formed in the receiving portion 23 so that the cargo can be loaded or unloaded in the receiving portion 23. [ The lower frame 22 and the receiving portion 23 are integrally formed in the cargo container 20 according to the embodiments of the present invention so that it is not possible to completely separate the receiving portion 23 from the lower frame 22 Do. For example, the lower frame 22 and the accommodating portion 23 may be integrally formed by cutting and bending the same hot-rolled steel sheet. In one embodiment of the present invention, the hot-rolled steel sheet may be formed by cutting and bending using a laser.

In order to reduce the weight of the cargo container 20 having an integrated structure, each part of the cargo container 20 can be constructed using the hot-rolled steel sheet having low weight and high strength in the embodiments of the present invention.

SS trailers were used for existing trailers, especially SS400. However, SS-based steel sheet has high rigidity but heavy weight. In addition, the tensile strength of the SS400 is about 490 N / mm 2 , which has a stiffness higher than that required by the wing-bed trailer and has a high weight due to this. In the embodiments of the present invention, the main skeleton structure of the cargo container 20 is designed using the ATOS-type automotive structural steel plate having low weight and high strength in order to overcome the disadvantages of existing materials.

For example, an ATOS 80 with a yield strength of about 675 N / mm 2 and a tensile strength of about 785 N / mm 2 , or an ATOS 100 with a tensile strength of about 980 N / mm 2 and a yield strength of about 784 N / mm 2 Can be used. The weight of the wing-bed trailer can be reduced by forming the cargo container 20 using such a steel plate. Particularly, the accommodating portion 23 of the cargo container 20 occupies the most weight in the entire trailer. By applying the lightweight design using the ATOS steel sheet to the side surface and the upper frame of the accommodating portion 23, Can be dramatically reduced. Since the receiving portion 23 receives the load of the load, the receiving portion 23 can be designed to maintain the minimum required stiffness by analyzing the maximum load considering the loading load.

In one embodiment of the present invention, the receiving portion 23 includes a wing body door assembly 230, and the side and ceiling portions of the loading space can be opened and closed by driving the wing body door assembly. The receptacle 23 connects between the vertical frame 232 and the vertical frame 232 connected to the bottom surface 231 and the bottom surface 231 and the wingbody door assembly 230 And an upper frame 233 coupled thereto. The wing body door assembly 230 is disposed on both sides of the receiving portion 23 and can be driven using a hydraulic cylinder (not shown) or the like. A container (not shown) made of wood or a metal plate, a non-ferrous metal or other suitable material is provided inside the accommodating portion 30 to facilitate the loading of the cargo, thereby preventing the cargo from being contaminated .
