본 발명은 차량 적재함 사이드 레일의 보강구조에 관한 것으로서, 더욱 상세하게는 덤프트럭 등의 적재물 중량 및 덤핑시 수직하중을 지지할 수 있는 차량 적재함 사이드 레일의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a vehicle loading box side rail, and more particularly, to a reinforcing structure of a vehicle loading box side rail capable of supporting a weight of a load such as a dump truck and a vertical load during dumping.

일반적으로, 덤프트럭 등의 화물용 차량에는 적재함이나 데크 등이 마운팅되어 있으며, 이러한 적재함이나 데크에 수하물을 적재하게 된다. 덤프 트럭이나 컨테이너 차량 등의 대형 차량에는 적재함이나 데크를 지지하기 위한 별도의 지지장치가 필요하다.In general, a loading vehicle or a deck is mounted on a cargo vehicle such as a dump truck, and the baggage is loaded on the loading tray or the deck. Large vehicles, such as dump trucks and container vehicles, require a separate support device to support the stacker or deck.

특히, 상용차량과 같은 대형차량에 적용되는 섀시 프레임은 도 1에 도시된 바와 같이 서로 이격 배치되는 한 쌍의 사이드레일(1)과 이들의 사이에 가로방향으로 연결되는 다수의 크로스멤버(2)로 구성되어 있다In particular, the chassis frame applied to a large vehicle such as a commercial vehicle is a pair of side rails (1) spaced apart from each other as shown in Figure 1 and a plurality of cross members (2) connected in the horizontal direction therebetween It consists of

상기 사이드레일(1)과 크로스멤버(2)들은 보통 리벳 결합 및 볼트 결합되며, 그 뒷쪽의 사이드레일(1)의 각 외측면으로는 일정 간격 이격된 위치로 다수 브라켓이 부착되어 있어 이에 현가장치용 리프스프링이 장착되도록 되어 있으며, 이러한 섀시프레임은 리프스프링이 사이에 배치되는 상태하에서 차축에 얹혀져 결합 됨과 아울러 그 상측 후부로는 적재함이 얹혀져 배치된다.The side rails 1 and the crossmembers 2 are usually riveted and bolted together, and a plurality of brackets are attached to each outer surface of the rear side rails 1 at predetermined intervals so that the suspension device is attached thereto. The leaf spring for the purpose is to be mounted, the chassis frame is mounted on the axle and coupled with the leaf spring interposed therebetween, the upper rear portion is placed on the loading tray.

이러한 상기 적재함은 운송화물을 적재하기 위한 것으로 상기 섀시프레임으로 얹히는 서브프레임(3)이 플로어패널과 결합되어 있다.The loading box is for loading freights, and a subframe 3 mounted on the chassis frame is combined with a floor panel.

그러나, 상기와 같은 구조는 덤핑 실린더 지지부위의 서브 프레임에 크랙이 발생된다. 이러한 크랙 문제에 의해 서브 프레임의 교환비용이 발생함에 따라 사용자의 불만이 과다하였다.However, such a structure causes cracks in the subframe of the dumping cylinder support. The user's dissatisfaction was excessive as the cost of subframe exchange occurred due to such a crack problem.

즉, 이러한 문제점을 해결하기 위해 현재 사용중인 서브 프레임의 안쪽에 보강판만을 추가할 경우 수직하중을 적용하면 단면적이 급격히 변화하는 보강판 하단부 구조에서 높은 응력이 집중되어 크랙이 발생되었다.That is, in order to solve this problem, when only the reinforcement plate is added to the inside of the currently used sub-frame, the vertical stress is applied, and a high stress is concentrated in the lower structure of the lower part of the reinforcement plate where the cross-sectional area changes rapidly.

또한, 도 2에 도시된 바와 같이 폐 단면구조나 더블 프레임 구조를 검토해본 결과, 벤딩(bending) 시에는 효과가 있으나 토션(torsion)시에는 강도적으로 취약한 문제점이 발생되었다.In addition, as a result of examining the closed cross-sectional structure or the double frame structure as shown in Figure 2, there is an effect when bending (bending), but a strength is weakly weak when torsion (torsion).

본 발명은 상기 문제점을 해결하기 위한 것으로서, 본 발명의 목적은, 사이드레일의 내측에 “ㄷ”형태의 보강부재를 용접함으로써 덤프트럭 등의 적재물 중량 및 덤핑시 수직하중을 지지할 수 있는 차량 적재함 사이드 레일의 보강구조를 제공하는 데 있다.The present invention is to solve the above problems, an object of the present invention, by welding a reinforcing member of the "c" type on the inside of the side rail vehicle loading capacity that can support the weight of the load such as a dump truck and vertical load during dumping To provide a side rail reinforcement structure.

또한, 본 발명의 다른 목적은 사이드레일의 상하 단면에 용접함으로써 용접 노치에 의한 응력집중을 최소화할 수 있는 차량 적재함 사이드 레일의 보강구조를 제공하는 데 있다.In addition, another object of the present invention is to provide a reinforcement structure of a vehicle storage side rail that can minimize the stress concentration by the welding notch by welding to the upper and lower end face of the side rail.

상기 본 발명의 목적을 달성하기 위한 본 발명에 의하면, 차량 적재함 사이드 레일 내측의 보강 구조에 있어서, 차량 적재함 사이드레일(11)의 내측 상하 단면에 플러그 용접(16)된“ㄷ”형태의 보강부재(15)가 설치된 것을 특징으로 하는 차량 적재함 사이드 레일의 보강구조를 제공한다.According to the present invention for achieving the object of the present invention, in the reinforcement structure of the inside of the vehicle loading box side rail, the reinforcement member of the "c" shape of the plug weld 16 in the upper and lower end surface of the inside of the vehicle loading box side rail 11 Provides a reinforcement structure of the vehicle loading box side rail, characterized in that 15 is installed.

이상과 같이 본 발명에 의하면, 차량 적재함 사이드레일의 내부에 “ㄷ”형태의 보강부재를 용접함으로써 덤프트럭 등의 적재물 중량 및 덤핑시 수직하중을 지지할 수 있다. 또한 사이드 레일의 상하 단면에 각각 플러그용접함으로써 용접 노치에 의한 응력집중을 최소화할 수 있다. 즉, 본 발명은 서브프레임의 비틀림 강성을 증가시켜 서브프레임의 내구력을 증대시키게 된다.According to the present invention as described above, by welding the reinforcing member of the "c" shape in the interior of the vehicle loading box side rail can support the weight of the load, such as dump truck and vertical load during dumping. In addition, it is possible to minimize stress concentration due to the welding notch by plug welding to the upper and lower end faces of the side rails, respectively. That is, the present invention increases the durability of the subframe by increasing the torsional rigidity of the subframe.
