Description
본 고안은 상용차용 프론트크로스멤버에 관한 것으로, 특히 중공부가 형성되어 충돌시에 충격에너지를 흡수할 수 있도록 되므로 승객의 안전과 차량의 파손을 방지할 수 있는 상용차용 프론트크로스멤버의 충격흡수구조에 관한 것이다.The present invention relates to a front cross member for a commercial vehicle. In particular, a hollow part is formed to absorb shock energy during a collision, and thus, a shock absorbing structure of a front cross member for a commercial vehicle that can prevent passenger safety and damage to a vehicle. It is about.
일반적으로, 상용차에는 차량의 뼈대역할을 하는 대략 사다리형성을 띠는 바닥프레임으로 구성되는 바, 상기 구조는 도 3 에 도시된 바와 같이 대략 'ㄷ'자 단면형상을 이루는 채널형태로 성형된 프론트크로스멤버(2)의 그 개구부속으로 두개의 긴막대 형태를 갖춘 프론트사이드멤버(1)의 일측면이 수직으로 맞대기하여 볼트를 매개로 체결되어지고, 상기 프론트사이드멤버(1)의 사이에는 칸막이 형태의 지지대들이 일정한 간격을 유지하면서 체결되어진다.In general, a commercial vehicle is composed of a floor frame having a substantially ladder-shape to serve as a bone of the vehicle, the structure is a front cross molded in the form of a channel forming a substantially 'c' cross-sectional shape as shown in FIG. One side of the front side member 1 having two long rod shapes into the opening of the member 2 is fastened vertically by a bolt, and is partitioned between the front side members 1. Supports are fastened at regular intervals.
그러나, 상기 프론트크로스멤버(2)는 차량 전방측으로 취부되어지므로 차량충돌 및 외부의 충격 등을 직접적으로 영향을 받는데 비해 그 단면형태가 충격흡수에 무관하여 조그만 충격에도 차량파손 및 승객의 안전에 위험이 따르는 문제가 있었다.However, since the front cross member 2 is mounted to the front side of the vehicle, the front cross member 2 is directly affected by the collision of the vehicle and the external impact, but its cross-sectional shape is irrelevant to the absorption of the shock, which is dangerous to damage to the vehicle and the safety of the passenger. There was a problem following this.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 프론트사이드멤버의 단면형태를 육각형으로 전환함으로서 중공부가 형성되어 차량 전방측으로부터의 모든 충격들을 흡수할 수 있게 되어 차량의 파손 및 승객의 안전을 보장할 수 있도록 된 상용차용 프론트크로스멤버의 충격흡수구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised to solve the above problems, and by converting the cross-sectional shape of the front side member into a hexagon, a hollow part is formed to absorb all the impacts from the front side of the vehicle, thereby preventing damage to the vehicle and The purpose is to provide a shock absorbing structure of the front cross member for commercial vehicles that can ensure the safety.

상기와 같은 목적을 달성하기 위한 본 고안은, 대략 육각형의 단면형상을 이루는 채널형태로 성형된 프론트크로스멤버의 일측면에 두 개의 긴 막대형태를 갖춘 프론트사이드멤버의 일측면이 수직으로 맞대기하여 용접되므로 체결되어지고, 상기 프론트사이드멤버(1)의 사이에는 칸막이형태의 지지대들이 일정한 간격으로 유지되면서 체결되어진다.The present invention for achieving the above object is, one side of the front side member having two long rods on one side of the front cross member formed in the form of a channel forming a substantially hexagonal cross-sectional shape, butt welded vertically Therefore, it is fastened, and the support members of the partition type are fastened while being maintained at regular intervals between the front side members 1.
따라서,상기 프론트크로스멤버는 직육면체의 중공부가 형성됨에 따라 차량 충돌 및 외부충격으로부터의 충격에너지를 상기 중공부가 흡수하게 된다.Therefore, the front cross member, as the hollow portion of the rectangular parallelepiped is formed, the hollow portion absorbs the impact energy from the vehicle collision and external impact.
이하 본 고안을 첨부된 예시도면을 참조하여 자세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 본 고안에 따른 프론트크로스멤버의 도시한 것이고, 도 2 는 본 고안에 따른 도 1 의 A부를 상세히 도시한 것인 바, 본 고안은 대략 판형상을 띠며 일측부에서 사선방향으로 성형되다 다시 작하방으로 성형되며 거듭 사선방향으로 성형되다 직하방으로 끝맺음을 하는 형태를 지니며, 그 단면이 육각형상의 채널형태로 된 프론트크로스멤버(2), 이 프론트크로스멤버(2)의 일측면에 두 개의 긴막대형태를 갖춘 프레임사이드멤버(1)의 일측면이 수직으로 맞대기하여 용접되므로, 상기 프론트사이드멤버(1)의 사이에는 칸막이형태의 지지대들이 일정한 간격으로 유지되면서 체결되어진다.1 is a front cross member according to the present invention, Figure 2 is a detailed view of the portion A of Figure 1 according to the present invention, the present invention has an approximately plate shape and is molded in an oblique direction at one side. It is formed in a downward direction and is formed in an oblique direction and ends in a straight line. The cross-section is formed of a front cross member (2) having a hexagonal channel shape, and on one side of the front cross member (2). Since one side of the frame side member 1 having two long rods is welded to each other vertically, the partition supporters are fastened while being maintained at regular intervals between the front side members 1.
따라서, 상기 프론트크로스멤버(2)의 단면이 직육면체로 형성되고 그 중앙부가 관통되어짐에 따라 직육면체의 중공부(2a)가 형성되어, 차량충돌 및 외부충격으로부터의 충격에너지를 상기 직육면체의 중공부(2a)가 1차적으로 흡수하게 된다.Accordingly, as the cross-section of the front cross member 2 is formed into a rectangular parallelepiped and the center portion thereof penetrates, a hollow portion 2a of the rectangular parallelepiped is formed, and the impact energy from the vehicle collision and external impact is transmitted to the hollow portion of the rectangular parallelepiped ( 2a) is primarily absorbed.
이상 설명한 바와 같이 본 고안에 의하면, 대략 'ㄷ'자 단면형상에서 직육면체의 단면형상으로 그 중앙부가 관통되어 직육면체의 중공부(2a)가 형성되므로 차량출돌 및 외부충격으로부터의 충격에너지를 1차적으로 흡수함에 따라 차체의 파손 및 승객의 안전을 보장할 수 있는 효과가 있다.As described above, according to the present invention, since the central portion penetrates from the approximately 'c' cross section to the cross section of the rectangular parallelepiped, the hollow portion 2a of the rectangular parallelepiped is formed, thereby primarily impact energy from vehicle rush and external shock. Absorption has the effect of ensuring damage to the vehicle body and passenger safety.
