Description

차량 연료탱크의 확장구조{The expansion structure of a fuel tank in vehicle}The expansion structure of a fuel tank in vehicle}

본 발명은 차량 연료탱크의 확장구조에 관한 것으로, 보다 상세하게는 현가장치의 일부로 구성하여 그 크기를 증가시킬 수 있도록 된 차량 연료탱크의 확장구조에 관한 것이다.The present invention relates to an expansion structure of a vehicle fuel tank, and more particularly, to an expansion structure of a vehicle fuel tank that can be configured to increase the size of a suspension device.

일반적으로 차량의 엔진으로 공급되는 연료를 수용하는 연료탱크는 통상, 차량의 후방부위에서 차체의 저면 부위로 구비되는데 즉, 도 1에 도시된 바와 같이 스페어타이어가 수용되는 차량의 후방부위를 이루는 스페어타이어웰(SW)에 인접되게 연료탱크(F)가 장착되되, 상기 스페어타이어웰(SW)과 연료탱크(F)사이에는 각 차륜에 장착된 현가장치(S)를 이루면서 양 쪽 차륜을 연결하면서 강성을 강화하는 크로스멤버(10)가 구비되어진다.In general, the fuel tank for receiving the fuel supplied to the engine of the vehicle is usually provided from the rear portion of the vehicle to the bottom portion of the vehicle body, that is, a spare that forms the rear portion of the vehicle in which the spare tire is accommodated as shown in FIG. Fuel tank (F) is mounted adjacent to the tire well (SW), between the spare tire well (SW) and the fuel tank (F) while forming a suspension (S) mounted on each wheel while connecting both wheels A cross member 10 for enhancing rigidity is provided.

그러나, 이와 같이 상기 스페어타이어웰(SW)과 연료탱크(F)사이로 양 쪽 차륜을 연결하는 크로스멤버(10)가 구비되어지면, 상기 스페어타이어웰(SW)쪽으로 형성되는 공간이 크로스멤버(10)의 크로스멤버폭(L')많 큼 가려지게 되어 결국, 상기 연료탱크(F)의 연료탱크폭(L)이 짧아져 그 크기가 줄어드는 단점이 있게 된다.However, when the cross member 10 for connecting both wheels is provided between the spare tire well SW and the fuel tank F as described above, a space formed toward the spare tire well SW is formed in the cross member 10. The cross-member width (L ') of the ()) is covered as much as the end, the fuel tank width (L) of the fuel tank (F) is shortened there is a disadvantage that the size is reduced.

또한, 이와 같이 양 쪽 차륜을 연결하는 크로스멤버(10)를 갖는 현가장치(S)는 연료탱크(F)의 폭을 줄이는 대신 그 두께를 차량의 지상고까지 크게 할 수 있지만 이와 같은, 지상고는 차량의 저부와 도로사이에 유지되는 간격으로서 낮추면 낮출수록 도로의 물체에 의한 연료탱크(F)의 파손 위험이 증가되어 그 증가율이 크지 못하다는 한계성을 갖게 된다.In addition, the suspension device (S) having a cross member 10 for connecting both wheels in this way can increase the thickness of the vehicle to the ground height of the vehicle instead of reducing the width of the fuel tank (F) as described above, The lower the interval is maintained between the bottom of the road and the lower the risk of damage to the fuel tank (F) by the object of the road increases the limit that the increase rate is not large.

그리고, 현가장치(S)의 구성을 달리하는 경우에는 연료탱크(F)의 크기도 달리 할 수 있는데 즉, 도 2에 도시된 바와 같이 그 측면으로 체결브라켓트(12)를 매개로 차륜부위로 장착되는 한 쌍의 링크(11,11')를 구비하면서 차체 폭을 따라 브라켓트부재(B)를 매개로 장착된 크로스멤버(10)의 안쪽으로 연료탱크(F)를 안착시키는 경우에는 전술한 경우에 비해 연료탱크(F)의 연료탱크폭(L)이 차량의 후방부위를 이루는 스페어타이어웰(SW)쪽으로 근접시킬 수 있어 그 폭을 증가시킬 수 있게 된다.In addition, when the configuration of the suspension device (S) is different, the size of the fuel tank (F) can also be different, that is, as shown in Figure 2 mounted to the wheel portion via the fastening bracket 12 to the side thereof as shown in FIG. When the fuel tank F is seated inside the cross member 10 mounted with the bracket member B along the width of the vehicle body while having a pair of links 11 and 11 ', In comparison, the fuel tank width L of the fuel tank F may be closer to the spare tire well SW forming the rear portion of the vehicle, thereby increasing its width.

여기서, 미 설명 도면 부호 11a,11a'는 충격 흡수 및 완충용 부시이다.Here, reference numerals 11a and 11a ', which are not described, are shock absorbing and buffering bushes.

그러나, 이와 같은 경우에는 연료탱크(F)의 연료탱크폭(L)이 증가되는데 반해 상기 크로스멤버(10)가 일정한 크로스멤버두께(W)를 갖고 있어 차량의 지상고가 일정함에 따라 연료탱크두께(Wf)가 크로스멤버두께(W)많 큼 줄어드는 한계가 있게 된다.However, in this case, while the fuel tank width L of the fuel tank F is increased, the cross member 10 has a constant cross member thickness W, and thus the fuel tank thickness ( There is a limit that Wf) decreases as much as the cross member thickness (W).

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 현가장치를 이루는 크로스멤버의 기능을 연료탱크로 대체시켜 연료탱크의 크기를 증가시키면서 연료탱크의 강성도 함께 증가시키도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and has an object of increasing the rigidity of the fuel tank while increasing the size of the fuel tank by replacing the function of the cross member forming the suspension device with the fuel tank.

상기와 같은 목적을 달성하기 위한 본 발명은, 현가장치를 구성하도록 양쪽의 차륜부위로 각각 장착되는 한 쌍의 링크가 연료탱크를 감싸 지지하는 서포터가 연료탱크의 상·하 부위를 감싸면서 양 끝단에서 서로 중첩되는 어퍼·로워홀더와, 이 홀더의 저면으로 구비되어 링크가 삽입·결합되는 체결브라켓트로 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention provides a supporter for supporting a pair of links, each of which is mounted to both wheel portions so as to form a suspension device, to surround the upper and lower portions of the fuel tank. The upper lower holder overlapping each other, and provided with a bottom bracket of the holder, characterized in that consisting of a fastening bracket is inserted and coupled to the link.

도 3은 본 발명에 따른 연료탱크의 취부 사시도를 도시한 것인바, 본 발명은 현가장치를 구성하도록 양쪽의 차륜부위로 각각 장착되는 한 쌍의 링크(11,11')가 연료탱크(F)를 감싸 지지하는 서포터(20)를 매개로 결합되되, 이 서포터(20)는 연료탱크(F)의 상·하 부위를 감싸면서 양 끝단에서 돌출된 플랜지(21a,22a)를 매개로 서로 중첩되는 어퍼·로워홀더(21,22)와, 상기 로워홀더(22)의 돌출된 플랜지(22a)저면으로 용접·접합되어 링크(11,11')의 부시(11a,11a')부위가 삽입·결합되도록 디귿자 단면형상으로 이루어진 체결브라켓트(23)로 이루어진다.Figure 3 is a perspective view of the mounting of the fuel tank according to the present invention, the present invention is a pair of links (11, 11 ') are respectively mounted to the wheel portion of both sides to constitute a suspension device fuel tank (F) The supporter 20 is wrapped and supported by the medium, and the supporter 20 overlaps each other through the flanges 21a and 22a protruding from both ends while surrounding the upper and lower portions of the fuel tank F. The upper and lower holders 21 and 22 are welded and joined to the bottom of the flange 22a protruding from the lower holder 22 to insert and engage the bushes 11a and 11a 'of the links 11 and 11'. It consists of a fastening bracket 23 made of a depressed cross-sectional shape as possible.

또한, 상기 서포터(20)는 현가장치의 구조상 링크(11,11')가 이중으로 요구되는 경우 서로 간격을 두고 연료탱크(F)를 감싸게 됨은 물론이다.In addition, the supporter 20 is of course the structural link of the suspension (11, 11 ') is required of the double wrap the fuel tank (F) at intervals from each other, of course.

한편, 상기 링크(11,11')가 현가장치의 성능이나 차량의 레이아웃(Lay out)상 연료탱크(F)의 하부부위로 위치되어야만 할 때에는 상기 링크(11,11')의 궤적에 간섭을 일으키지 않도록 해야되므로 이를 위해, 상기 연료탱크(F)의 저면으로 도 4에 도시된 바와 같이 링크(11,11')의 스트로크(Stoke)에 따른 이동 궤적을 방해하지 않도록 글로브(f)가 형성되어진다.On the other hand, when the links 11 and 11 'need to be positioned at the lower part of the fuel tank F on the performance of the suspension system or the layout of the vehicle, the tracks 11 and 11' interfere with the trajectories of the links 11 and 11 '. For this purpose, the globe f is formed so as not to interfere with the movement trajectory according to the stroke of the links 11 and 11 'to the bottom of the fuel tank F. Lose.

이에 따라, 본 발명에 따른 연료탱크(F)는 그 양단에 링크(11,11')가 결합된 서포터(20)가 스페어타이어웰(SW)과 연료탱크(F)사이로 위치되거나 또는 연료탱크(F)를 안쪽으로 안착시키는 크로스멤버(10)와 달리 연료탱크(F)의 외부를 감싸 지지하게 되는데 이는, 상기 서포터(20)가 연료탱크(F)의 강성을 보강함은 물론 연료탱크(F)자체가 크로스멤버의 기능을 하는 것을 의미하므로 결국, 상기 연료탱크(F)의 연료탱크폭(L)과 연료탱크두께(Wf)를 각각 크로스멤버(10)가 독립적으로 장착되는 경우에 비해 더욱 크게 확장시킬 수 가 있게 되는 것이다.Accordingly, in the fuel tank F according to the present invention, the supporter 20 having the links 11 and 11 'coupled to both ends thereof is positioned between the spare tire well SW and the fuel tank F or the fuel tank F Unlike the cross member 10 for seating the F inwardly is wrapped around the outside of the fuel tank (F), which supports the support tank 20, as well as reinforce the rigidity of the fuel tank (F) of the fuel tank (F) Since it means that it functions as a cross member, the fuel tank width (L) and the fuel tank thickness (Wf) of the fuel tank (F), respectively, compared to the case where the cross member 10 is mounted independently. It can be greatly expanded.

즉, 상기 연료탱크(F)의 연료탱크폭(L)이 크로스멤버(10)가 스페어타이어웰(SW)과 연료탱크(F)사이로 위치되는 경우에 비해 본 발명은 연료탱크폭(L)이 크로스멤버(10)의 크로스멤버폭(L')많 큼 더 증가된 확장폭(L")을 형성함과 더불어 연료탱크두께(Wf)가 크로스멤버두께(W)많 큼 연료탱크폭(L)이 더 증가된 확장두께(Wf')를 형성하게 된다.That is, the fuel tank width (L) of the fuel tank (F) is compared to the case where the cross member 10 is located between the spare tire well (SW) and the fuel tank (F) the fuel tank width (L) is The cross member width (L ') of the cross member 10 is much larger and the expanded width (L ") is formed, and the fuel tank thickness (Wf) is much larger than the cross member thickness (W). This further increases the extension thickness Wf '.

이상 설명한 바와 같이 본 발명에 의하면, 연료탱크를 이용해 크로스멤버기능을 하도록 되어 크로스멤버의 삭제에 따른 연료탱크의 용적을 증가함은 물론 연료탱크를 감싸면서 지지하게 되어 연료탱크의 강성도 강화시킬 수 있는 효과가 있게 된다.As described above, according to the present invention, the fuel tank has a cross member function to increase the volume of the fuel tank due to the deletion of the cross member, as well as to surround the fuel tank and support the fuel tank, thereby increasing the rigidity of the fuel tank. It will work.
