본 고안은 화물차의 리어 크로스멤버 설치구조에 관한 것으로, 더욱 상세하게는 화물차의 백패널의 강도를 보완할 수 있도록 백패널 하부에 설치되는 리어 크로스멤버의 결합구조를 개선한 화물차의 리어 크로스멤버 설치구조에 관한 것이다.The present invention relates to a rear cross member installation structure of a truck, and more particularly, to a rear cross member installation structure of a truck that has improved coupling structure of a rear cross member installed under the back panel to supplement the strength of the back panel of a truck. It is about.
일반적으로 화물차는 캐빈과 적재부로 구성되며, 예시도면 제1도내지 제2도에서 보인 것과 같이, 캐빈(11)의 후면은 강판재의 백패널(2)로 바디를 구성하고 있으며, 백패널(2)의 하부는 언더바디의 골격으로 강도나 강성을 높이기 위하여 자동차의 진행방향에 대하여 직각으로 설치되어 차체 좌우방향의 비틀림이나 휘어짐을 방지하는 리어 크로스멤버(10)와 용접되어 있으며, 백패널(2)의 중앙부는 직사각형상의 다수개의 비드(12)가 백패널(2)의 길이방향으로 형성되어 백패널(2)의 단면형상이 요철모양을 이루도록 하여 백패널(2)이 강성을 유지하도록 하고 있다.In general, the van is composed of a cabin and a loading portion, and as shown in the first and second exemplary drawings, the rear surface of the cabin 11 constitutes a body with a back panel 2 of steel sheet, and the back panel 2 The lower part is an underbody skeleton, which is installed at right angles to the traveling direction of the vehicle to increase strength and rigidity, and is welded to the rear cross member 10 that prevents twisting or bending in the left and right directions of the vehicle body. The plurality of rectangular beads 12 are formed in the longitudinal direction of the back panel 2 so that the cross-sectional shape of the back panel 2 is concave and convex so that the back panel 2 maintains rigidity.
또한, 캐빈(11)의 플로어(3)의 끝단부도 리어 크로스멤버(10)의 일단과 용접되어 강도를 지지받게 되어 있다.In addition, the end of the floor 3 of the cabin 11 is also welded with one end of the rear cross member 10 to support the strength.
그런데 이와같은 종래의 리어 크로스멤버(10)와 백패널(2)의 결합구조는 백패널(2)의 일단에 리어 크로스멤버(10)의 일단이 용접되고 다른 일단에는 플로어(3)가 용접되어 개단면구조를 이루고 있어 백패널(2)과 리어 크로스멤버(10)가 후방충격에 취약한 문제가 있었다.However, in the conventional structure of the rear cross member 10 and the back panel 2, one end of the rear cross member 10 is welded to one end of the back panel 2, and the floor 3 is welded to the other end. As a result, the back panel 2 and the rear cross member 10 were vulnerable to rear shock.
따라서 본 고안은 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 백패널과 플로어의 강도를 유지하기위한 리어 크로스멤버의 구조가 폐단면을 이루도록하여 백패널과 플로어에 결합하고 백패널과 플로어를 결합하는 보강재를 설치하여 백패널의 후방충격에 대한 강성을 높일수 있는 화물차의 리어 크로스멤버 설치구조를 제공하는데 본 고안의 목적이 있다.Therefore, the present invention has been devised to solve such a conventional problem, the structure of the rear cross member for maintaining the strength of the back panel and the floor to form a closed cross-section to the back panel and the floor and to reinforce the back panel and floor It is an object of the present invention to provide a rear cross member installation structure of a van that can increase the rigidity against the rear impact of the back panel by installing a.
이와같은 목적을 실현하기 위한 본 고안의 구성 및 작용효과를 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The construction and effect of the present invention for realizing such an object will be described in detail with the accompanying exemplary drawings as follows.
본 고안은 리어 크로스멤버(1)의 양 선단부를 백패널(2)의 일단과 결합하여 리어 크로스멤버(1)의 형상을 폐단면으로 형성하고, 리어 크로스멤버(1)의 일단에 플로어(3)의 선단부를 결합하고, 백패널(2)의 일단과 플로어(3)를 직접 결합하는 보강재(4)를 설치한 구조로 되어 있다.The present invention combines both ends of the rear cross member 1 with one end of the back panel 2 to form the shape of the rear cross member 1 as a closed cross section, and the floor 3 at one end of the rear cross member 1. The reinforcing material 4 which couple | bonds the front-end | tip of the back panel 2, and directly couples the one end of the back panel 2, and the floor 3 is provided.
예시도면 제3도는 본 고안의 리어 크로스멤버의 설치구조를 보인 단면도이며, 제4도는 본 고안의 리어 크로스멤버의 설치구조를 보인 사시도이며, 제5도는 본 고안의 리어 크로스멤버의 보강재를 보인 사시도이다.Exemplary Drawing 3 is a cross-sectional view showing the installation structure of the rear cross member of the present invention, Figure 4 is a perspective view showing the installation structure of the rear cross member of the present invention, Figure 5 is a perspective view showing the reinforcement of the rear cross member of the present invention to be.
리어 크로스멤버(1)는 한쪽면이 개방된 사각기둥형상을 이루고 있으며, 개방된 한쪽면이 백패널(2)을 향하도록 하여 리어 크로스멤버(1)의 양 선단부가 백패널(2)의 일단에 용접으로 결합되어 결과적으로 리어 크로스멤버(1)는 폐단면형상을 이뤄 백패널(2)에 가해지는 후방충격을 충분히 지탱할 수 있는 구조임을 알수 있다.The rear cross member 1 has a rectangular pillar shape with one side open, and the open side faces the back panel 2 so that both ends of the rear cross member 1 are welded to one end of the back panel 2. As a result, it can be seen that the rear cross member 1 is a structure capable of sufficiently supporting the rear impact applied to the back panel 2 by forming a closed cross-sectional shape.
더불어 플로어(3)는 폐단면형상을 이루는 리어 크로스멤버(1)의 일단에 용접되어 결합되며, 이는 종래의 개단면형상을 이루는 리어 크로스멤버(10)의 끝단부에 용접되는 형상보다 훨씬 견고하게 지지받을 수 있음을 알 수 있으며, 플로어(3)의 일단과 백패널(1)의 일단에 직접 연결되는 강판재의 보강재(4)가 백패널(2)과 플로어(3)를 지지할 수 있도록 용접되어 백패널(2)의 후방충격에 대한 강성을 높일뿐만아니라 플로어(3)를 하부에서 지탱할수 있도록 되어 있다.In addition, the floor (3) is welded to one end of the rear cross member (1) forming a closed cross-sectional shape, which is much more robust than the shape welded to the end of the rear cross member (10) forming a conventional open cross-sectional shape. It can be seen that it can be supported, the reinforcing material (4) of the steel sheet material directly connected to one end of the floor (3) and one end of the back panel (1) is welded to support the back panel (2) and the floor (3) In addition to increasing the rigidity against the rear impact of (2), it is possible to support the floor (3) from the bottom.
따라서 본 고안에 의하면 백패널의 후방충격에 대한 강성을 높일 수 있어 탑승자의 안전성을 향상할 수 있는 효과를 가져올 수 있다.Therefore, according to the present invention can increase the rigidity of the rear impact of the back panel can bring the effect of improving the safety of the occupants.
