Description

자동차 프레임의 사이드 멤버Side members of a car frame

본 고안은 자동차 프레임의 사이드 멤버에 관한 것이며, 상세하게는 겹치기 상자형 단면을 가진 프레임의 사이드 멤버에 관한 것이다.The present invention relates to a side member of an automobile frame, and more particularly to a side member of a frame having an overlapping box-shaped cross section.

프레임은 자동차가 주행중에 노면으로부터 받는 충격이나 화물의 하중 등에 의하여 생기는 굽힘 등에 의하여 충분히 견딜 수 있는 강성을 구비함과 동시에 가벼워야 한다.The frame should be light and rigid enough to withstand the bending caused by the impact of the road or the load of the cargo.

상기한 요구에 부응하기 위하여 버스, 트럭 등에는 사이드 멤버 사이에 수개의 크로스멤버를 결합한 H형 프레임이 많이 사용되고, 상기한 사이드 멤버 및 크로스 멤버의 단면은 L형, ㄷ형, ㅁ형의 것이 많이 사용되고 있으며 상기한 ㅁ형 단면을 가진 사이드 멤버 즉 겹치기 상자형 단면의 것은 사이드 멤버 본체에 보강부재를 용접 결합하여 제조하고 있는 바, 종래 겹치기 상자형 단면의 사이드 멤버는 도 4에 도시한 바와 같이 멤버 본체(1)를 ㄷ형으로 성형하고, 상기 멤버 본체(1)의 내면에 써포터(2)를 일정간격으로 용접 결합하여 상기 멤버 본체(1)의 개방부 내면에 보강부재(3)를 용접 결합할때 상기 써포터(2)의 정상부에 보강부재(3)의 내면을 접촉시킨 후 용접 결합하고 있으며, 상기한 써포터(2)는 멤버 본체(1)와 보강부재(3)의 프레스 성형시에 생긴 뒤틀림 등의 변형을 보정하는 기준으로 활용하고 멤버본체(1)와 보강부재(3) 사이의 간격을 일정하게 유지하는 기능을 수행하는 것이다.In order to meet the above requirements, buses, trucks, etc., H-frames in which several cross-members are combined between side members are frequently used, and the cross-sections of the side members and cross-members of L-type, C-type, and K-type are widely used. The side member having the ㅁ -shaped cross section, that is, the overlapping box-shaped cross section, is manufactured by welding a reinforcing member to the side member main body. As shown in FIG. 4, the side member of the overlapping box-shaped cross-section is a member main body (1). ) Is formed in a c-shape, and the supporter 2 is welded to the inner surface of the member main body 1 at a predetermined interval to weld the reinforcing member 3 to the inner surface of the opening of the member main body 1. The inner surface of the reinforcing member 3 is brought into contact with the top of (2) and welded to each other. The supporter 2 is formed during press molding of the member main body 1 and the reinforcing member 3. To utilize the basis for correcting the variation of doubt, etc. and functions to maintain a constant distance between the body member 1 and the reinforcing member (3).

그러나 상기한 써포터(2)는 멤버 본체(1)의 내면에 설치되어 있어서 보강부재(3)를 멤버 본체(1)에 용접결합할때 보강부재(3)의 내면이 써포터(2)의 정상부에 접촉되어 있는지의 여부를 육안으로 확인할 수가 없으므로 멤버 본체(1)와 보강부재(3)의 성형시에 발생한 변형의 보정이 정확하지 못하고 멤버 본체(1)와 보강부재(3) 사이의 간격이 균일하지 못하게 되는 것이다.However, the supporter 2 is installed on the inner surface of the member main body 1 so that when the reinforcing member 3 is welded to the member main body 1, the inner surface of the reinforcing member 3 is placed on the top of the supporter 2. Since it is impossible to visually check whether or not there is contact, the correction of deformation occurring during the molding of the member main body 1 and the reinforcing member 3 is not accurate and the spacing between the member main body 1 and the reinforcing member 3 is uniform. You will not be able to.

상기와 같이 멤버 본체(1)와 보강부재(3) 사이의 간격이 균일하지 못하면 사이드 멤버 사이에 결합되는 크로스 멤버의 용접 결합시에 크로스 멤버와 양 사이드 멤버 사이의 간격의 불일치로 크로스 멤버의 결합이 불가능하거나 용접결합시에 작업공수가 많이 소요되고, 또한 사이드 멤버에 부착되는 브래킷 등의 부착공차가 크게되어 크래킷 등에 설치되는 관련부품의 설치작업이 곤란하거나 작업공수가 많이 소요되는 문제점이 있는 것이다.If the gap between the member body 1 and the reinforcing member 3 is not uniform as described above, when the cross member is welded to the side member, the cross member is coupled by the mismatch between the cross member and both side members. This is impossible or requires a lot of labor during welding, and the mounting tolerance of the bracket, etc. attached to the side member is large, it is difficult to install the relevant parts to be installed on the cracks, etc. will be.

본 고안은 상기한 문제점을 시정하여 겹치기 상자형 단면의 사이드 멤버 본체와 보강부재를 결합할때 그 사이의 간격을 육안으로 확인하면서 신속하고 편리하게 일정하게 유지할 수 있도록 한 자동차 프레임의 사이드 멤버를 제공하는 것을 목적으로 한다.The present invention corrects the above problems and provides a side member of a vehicle frame that allows the user to quickly and conveniently maintain a constant distance while visually checking the space between the side member body and the reinforcing member of the overlapping box-shaped cross section. It aims to do it.

상기한 목적을 달성하기 위하여, 본 고안은 멤버 본체와 보강부재의 대응위치에 일정간격의 구멍을 형성하고, 멤버 본체와 보강부재 사이에 형성하려는 간격과 동일한 길이로 형성되고 양단에 지지돌기가 형성된 써포터를 그 지지돌기를 상기 구멍에 삽입한 후 용접 결합하여서 된 것이다.In order to achieve the above object, the present invention is to form a hole at a predetermined interval in the corresponding position of the member body and the reinforcing member, and formed in the same length as the gap to be formed between the member body and the reinforcing member, the support protrusions are formed at both ends The supporter is made by inserting the support protrusion into the hole and then welding it.

본 고안은 도 2 및 도 3에 도시한 바와 같이 멤버 본체(1)와 보강부재(3)의 대응위치에 일정한 간격의 구멍(10)(11)을 형성하고, 멤버 본체(1)와 보강부재(3) 사이에 형성하려는 간격(t)과 동일한 길이로 형성되고 양단에 지지돌기(13)(13')를 형성한 써포터(12)를 그 지지돌기(13)(13')를 상기 구멍(10)(11)에 삽입한 후 용접결합하여서 된 것이다.According to the present invention, as shown in FIGS. 2 and 3, holes 10 and 11 at regular intervals are formed at corresponding positions of the member main body 1 and the reinforcing member 3, and the member main body 1 and the reinforcing member are formed. (3) the supporter 12 formed with the same length as the space | interval t to be formed between them, and the support protrusions 13 and 13 'formed at both ends thereof, and the support protrusions 13 and 13' are formed in the hole ( 10) (11) and then welded together.

이상과 같은 본 고안은 멤버 본체(1)에 형성된 구멍(10)에 써포터(12)의 일단에 형성한 지지돌기(13)를 삽입한 후 멤버 본체(1)의 내면과 써포터(12)를 용접결합하며, 멤버 본체(1)의 개방부에 보강부재(3) 끼울때 써포터(12)의 타단에 형성한 지지돌기(13')에 보강부재(3)에 형성한 구멍(10)을 끼운후 멤버 본체(1)와 보강부재(3)를 크램핑하여 지지돌기(13')와 보강부재(3)의 표면을 일치시킨 후 지지돌기(13')와 보강부재(3)를 용접결합하고 멤버 본체(1)와 보강부재(3)를 용접결합하는 것이다.According to the present invention as described above, after inserting the support protrusion 13 formed at one end of the supporter 12 into the hole 10 formed in the member main body 1, the inner surface of the member main body 1 and the supporter 12 are welded. When the reinforcing member (3) is fitted to the opening of the member main body 1, the hole 10 formed in the reinforcing member (3) is inserted into the support protrusion (13 ') formed at the other end of the supporter (12). After clamping the member main body 1 and the reinforcing member 3 to match the surface of the support protrusion 13 ′ and the reinforcing member 3, the support protrusion 13 ′ and the reinforcing member 3 are welded to each other. The main body 1 and the reinforcing member 3 are welded together.

상기와 같이 멤버 본체(1)와 보강부재(3)를 결합할때 멤버 본체(1)와 보강부재(3) 사이의 간격은 써포터(12)의 길이와 동일하게 되기 때문에 멤버 본체(1)와 보강 부재(3)의 프레스 성형시에 발생된 변형이 정확하게 보정되고 그 간격도 일정하게 유지할 수 있는 것이다.As described above, when the member main body 1 and the reinforcing member 3 are coupled, the distance between the member main body 1 and the reinforcing member 3 becomes equal to the length of the supporter 12. Deformation generated at the time of press molding of the reinforcing member 3 can be corrected accurately and its spacing can be kept constant.

이상과 같이 본 고안은 멤버 본체와 보강부재의 간격을 일정하게 유지하므로서 사이드 멤버 사이에 크로스 멤버를 결합할때 또는 사이드 멤버에 브래킷 등을 설치하고 상기 브래킷에 관련부픔을 설치할 때 공차관리가 용이하여 작업공수를 절감하고, 그 조립작업이 신속하고 편리한 효과 등이 있는 것이다.As described above, the present invention maintains a constant distance between the member body and the reinforcing member, so that tolerance management is easy when the cross member is coupled between the side members or when the bracket is installed on the side member and the related parts are installed on the bracket. Reduced labor and the assembly work has a quick and convenient effect.
