도 2는 본 발명에 따른 전륜 우물정자형 서브프레임을 도시한 도면이다. 2 is a view showing a front wheel well sperm-shaped subframe according to the present invention.

도면을 참조하면, 전륜 우물정자형 서브프레임(20)은 제1 어퍼·로워 패널(22)(24)과 좌·우 마운팅 브라켓 어퍼패널(26)(28)을 일체화시켜 형성하며, 상기 제1 어퍼·로워 패널(22)과, 제2 어퍼·로워 패널(24)간을 좌·우 사이드 멤버(26)(27)로 연결되어 구성된다.Referring to the drawings, the front wheel well sperm-shaped subframe 20 is formed by integrating the first upper lower panels 22 and 24 and the left and right mounting bracket upper panels 26 and 28, and the first upper The lower panel 22 and the second upper lower panel 24 are connected by left and right side members 26 and 27.

상기한 전륜 우물정자형 서브프레임은 10개의 패널(6개의 어셈블리)로 구성되어 패널수 2개가 축소되게 된다. 즉, 종래 기술에서 제1 어퍼·로워 패널(22)(24)과 좌,우 마운팅 브라켓트 어퍼패널(25)(28)이 별도로 구비되던 것을 일체화하여 패널수를 축소한 것이다. The front wheel well sperm-type subframe consists of ten panels (six assemblies), thereby reducing the number of two panels. That is, in the prior art, the first upper lower panels 22 and 24 and the left and right mounting bracket upper panels 25 and 28 are separately provided to reduce the number of panels.

그리고 4개의 어셈블리인 좌,우 사이드멤버(26)(27) 제1,2 어퍼·로워 패널(22)(24)는 각각 구비되고 있는 어퍼 패널과 로어 패널을 용접하여 각각의 어셈블리를 구성하게 된다. The left and right side members 26 and 27, which are four assemblies, and the first and second upper and lower panels 22 and 24, respectively, are welded to the upper panel and the lower panel, respectively, to form respective assemblies. .

또 서브프레임(20)의 전면 좌,우에 형성되는 2개의 마운팅 브라켓트좌,우 로워패널(26-1)(28-1)는 용접없이 그대로 2개의 어셈블리로 둔다. 즉, 6개의 어셈블리를 용접하여 1개의 서브프레임 컴플리트를 구성하게 된다.In addition, the two mounting brackets left and right, which are formed on the front left and right sides of the subframe 20, the lower panels 26-1 and 28-1 are left as two assemblies without welding. That is, six assemblies are welded to form one subframe complete.

상기한 바와 같이 이루어지는 본 발명의 작용을 설명하면, 우물정자형 서브프레임(20)은 좌,우 마운팅 브라켓트 어퍼패널(25)(28)을 제1어퍼·로워 패널(22)(24)과 일체화 시킴에 따라 패널수 2개의 삭제가 가능하게 된 것이다. Referring to the operation of the present invention made as described above, the well sperm-type subframe 20 integrates the left and right mounting bracket upper panels 25 and 28 with the first upper and lower panels 22 and 24. As a result, two panels can be deleted.

이에 따라 좌,우 마운팅 브라켓트 어퍼 패널(25)(28)이 일체로 형성됨에 따 라 종래의 긴 용접 길이보다 대폭 축소할 수 있게 된다. 즉, 동일 형상의 종래 우물정자형 서브프레임(20)에 비해 본 발명의 용접길이는 약 15%정도 줄어들어 제작 생산단가를 약 5~10%가량 축소가 가능하게 된다. Accordingly, as the left and right mounting bracket upper panels 25 and 28 are integrally formed, they can be greatly reduced than the conventional long welding length. That is, compared to the conventional well sperm-shaped subframe 20 of the same shape, the welding length of the present invention is reduced by about 15%, thereby reducing the manufacturing cost by about 5 to 10%.

그리고 제1 어퍼·로워패널(22)과 제2 어퍼·로워패널(24)을 사이드멤버(26)(27)로 연결되는 것이 용접이 아닌 단일패널로 연결됨에 따라 강성 증대가 향상된다.As the first upper lower panel 22 and the second upper lower panel 24 are connected to the side members 26 and 27 by a single panel instead of welding, the increase in rigidity is improved.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술 분야에서 통상의 지식을 가진자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this and is given by the person of ordinary skill in the art to the following, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

본 발명은 좌,우 마운팅 브라켓트를 부착하기 위한 종래의 긴 용접 길이보다 대폭 축소할 수 있게 되는 효과가 있다.The present invention has the effect that can be significantly reduced than the conventional long welding length for attaching the left, right mounting bracket.

동일 형상의 종래 우물정자형 서브프레임에 비해 본 발명의 용접길이가 줄어들어 제작 생산단가의 축소가 가능하게 되는 효과가 있다. Compared with the conventional well sperm-shaped subframe of the same shape, the welding length of the present invention is reduced, thereby reducing the production cost.

그리고 제1 어퍼·로워패널과 제2 어퍼·로워패널을 사이드멤버로 연결하는 것이 용접이 아닌 단일패널로 연결됨에 따라 강성이 증대되는 효과가 있다.In addition, connecting the first upper lower panel and the second upper lower panel by the side member is connected to a single panel rather than welding, thereby increasing the rigidity.
