ところで、上記公報に記載された燃料タンクはバンドを介して車体に固定され ており、そのバンドに断熱カバーの中央部が支持されるようになっている。しか しながら、一般に断熱カバーは比較的に剛性が低い薄肉の合成樹脂によって形成 されるため、その外周部が自己の重量によって下向きに垂れ下がってしまい、自 動車の走行に伴う振動によって騒音を発する等の不都合があった。 By the way, the fuel tank described in the above publication is fixed to the vehicle body through a band, and the band supports the central portion of the heat insulating cover. However, since the heat insulating cover is generally made of a thin synthetic resin having a relatively low rigidity, the outer periphery of the heat insulating cover hangs downward due to its own weight, which causes noise due to vibrations of the vehicle. There was an inconvenience.
【０００４】 本考案は前述の事情に鑑みてなされたもので、燃料タンクの下部を覆う断熱カ バーの外周部の剛性を向上させることを目的とする。The present invention has been made in view of the above circumstances, and an object thereof is to improve the rigidity of the outer peripheral portion of the heat insulating cover that covers the lower portion of the fuel tank.

【０００９】 図１に示すように、自動車Ｖの車体前部には左右の前輪Ｗｆを駆動するエンジ ンＥが搭載されており、このエンジンＥに燃料を供給する燃料タンクＴが左右の 後輪Ｗｒ間に配設される。エンジンＥから後方に延びる排気管Ｐは、燃料タンク Ｔの前面から右側面を迂回し、車体後部に設けたマフラーＭに接続される。燃料 タンクＴの下面は、排気管Ｐからの熱や路面からの熱が燃料タンクＴに直接作用 することを防止すべく、合成樹脂製の断熱カバーＣによって覆われる。As shown in FIG. 1, an engine E for driving left and right front wheels Wf is mounted on the front part of a vehicle body of a vehicle V, and a fuel tank T for supplying fuel to this engine E is equipped with rear left and right wheels. It is arranged between Wr. An exhaust pipe P extending rearward from the engine E bypasses the front surface and the right side surface of the fuel tank T and is connected to a muffler M provided at a rear portion of the vehicle body. The lower surface of the fuel tank T is covered with a heat insulating cover C made of synthetic resin in order to prevent heat from the exhaust pipe P and heat from the road surface from directly acting on the fuel tank T.
【００１０】 次に、図２〜図７に基づいて燃料タンクＴ及び断熱カバーＣの構造を詳細に説 明する。Next, the structures of the fuel tank T and the heat insulating cover C will be described in detail with reference to FIGS. 2 to 7.
【００１１】 燃料タンクＴは、上半部１と下半部とを接合面３において上下に接合してなる 中空容器体であって、その上半部１の上面からは図示せぬ給油口に向けてフィラ ーパイプ４及びブリーザチューブ５が車体左後方に延出するとともに、エンジン Ｅに向けてフィードパイプ６、リターンパイプ７及びベントチューブ８が車体前 方に延出する。The fuel tank T is a hollow container body in which an upper half portion 1 and a lower half portion are vertically joined at a joint surface 3, and an upper surface of the upper half portion 1 is connected to a filler port (not shown). The filler pipe 4 and the breather tube 5 extend toward the left rear of the vehicle body, and the feed pipe 6, the return pipe 7 and the vent tube 8 extend toward the front of the vehicle toward the engine E.
【００１２】 図２から明らかなように、燃料タンクＴは、車体の左右両側を前後に延びる一 対のサイドフレーム９，１０と、これらサイドフレーム９，１０を左右に接続す る前後一対のクロスメンバ１１，１２と、図示せぬフロアパネルの下面とによっ て画成される空間に収納される。As is apparent from FIG. 2, the fuel tank T includes a pair of side frames 9 and 10 extending front and back on both left and right sides of the vehicle body and a pair of front and rear cross frames connecting the side frames 9 and 10 to the left and right. It is housed in the space defined by the members 11 and 12 and the lower surface of the floor panel (not shown).
【００１３】 図６及び図７から明らかなように、燃料タンクＴは、２本のバンド１３，１３ によって前記一対のクロスメンバ１１，１２に固定される。即ち、燃料タンクＴ の下半部２には車体前後方向に延びるバンド溝２1 ，２1 が凹設されており、こ れらバンド溝２1 ，２1 に嵌合するバンド１３，１３の前端がボルト１４，１４ を介して前側のクロスメンバ１１に固定されるとともに、その後端に設けた取付 部材１５，１５がボルト１６，１６を介して後側のクロスメンバ１２に固定され る。As is apparent from FIGS. 6 and 7, the fuel tank T is fixed to the pair of cross members 11, 12 by the two bands 13, 13. That is, the lower half portion 2 of the fuel tank T is provided with band grooves 2 1 and 2 1 extending in the front-rear direction of the vehicle body. The band grooves 2 1 and 2 1 which are fitted in the band grooves 2 1 and 2 1 The front end is fixed to the front cross member 11 via bolts 14 and 14, and the mounting members 15 and 15 provided at the rear end are fixed to the rear cross member 12 via bolts 16 and 16.
【００１４】 また、燃料タンクＴの下半部３には前記２本のバンド溝２1 ，２1 と平行に延 びる３本のビード２2 ，２2 ，２2 が凹設されており、それらビード２2 ，２2 ，２2 の頂面に皿状の仕切り板１７がスポット溶接により固定される。仕切り板 １７の外周部と燃料タンクＴの内面との間には、相互に連通する空間１８…が形 成される。従って、燃料タンクＴに残留するガソリンの容量が所定の値（例えば ４０％）以下に減少しても、前記空間１８…は常に一定量のガソリンによって満 たされる。而して、空間１８…に閉じ込められたガソリンによって下方からの熱 を遮断することにより、燃料タンクＴ内のガソリンの蒸発を抑制することができ る。Further, in the lower half portion 3 of the fuel tank T, three beads 2 2 , 2 2 , 2 2 extending in parallel with the two band grooves 2 1 , 2 1 are recessed, A dish-shaped partition plate 17 is fixed by spot welding to the top surfaces of the beads 2 2 , 2 2 , 2 2 . Between the outer peripheral portion of the partition plate 17 and the inner surface of the fuel tank T, spaces 18 that communicate with each other are formed. Therefore, even if the capacity of the gasoline remaining in the fuel tank T is reduced to a predetermined value (for example, 40%) or less, the spaces 18 ... Are always filled with a constant amount of gasoline. Thus, by shutting off the heat from below by the gasoline trapped in the space 18, the evaporation of the gasoline in the fuel tank T can be suppressed.
【００１５】 図３から明らかなように、断熱カバーＣは、燃料タンクＴの平面形状よりも僅 かに大きく形成された合成樹脂製の部材であって、その中央部において前記２本 のバンド１３，１３に支持されるとともに、その外周部において前記サイドフレ ーム９，１０及び後側のクロスメンバ１２に支持される。As is apparent from FIG. 3, the heat insulating cover C is a synthetic resin member formed slightly larger than the planar shape of the fuel tank T, and the two bands 13 are formed in the center thereof. , 13 and the outer peripheral portions thereof are supported by the side frames 9 and 10 and the rear cross member 12.
【００１６】 即ち、各バンド１３の下面には２個の取付ボス１９，１９がスポット溶接され ており、この取付ボス１９，１９にクリップ２０，２０を介して断熱カバーＣの 中央部が支持される（図６参照）。また、断熱カバーＣの外周部の左側縁は３個 のボルト孔２１…が、右側縁には３個のボルト孔２２…が、後縁には２個のボル ト孔２３…がそれぞれ穿設されており、ボルト孔２１…を貫通するボルト２４… は左側のサイドフレーム９に、ボルト孔２２…を貫通するボルト２５…は右側の サイドフレーム１０に、ボルト孔２３…を貫通するボルト２６…はクロスメンバ １２にそれぞれ螺入される（図４及び図５参照）。而して、断熱カバーＣは燃料 タンクＴの下部を覆うように支持される。That is, two mounting bosses 19 and 19 are spot-welded to the lower surface of each band 13, and the central portion of the heat insulating cover C is supported by the mounting bosses 19 and 19 via clips 20 and 20. (See FIG. 6). Further, three bolt holes 21 ... Are provided on the left side edge of the heat insulating cover C, three bolt holes 22 ... are provided on the right side edge, and two bolt holes 23 ... Are provided on the rear edge. The bolts 24 penetrating the bolt holes 21 ... are to the left side frame 9, the bolts 25 penetrating the bolt holes 22 ... are to the right side frame 10, and the bolts 26 penetrating the bolt holes 23. Are respectively screwed into the cross members 12 (see FIGS. 4 and 5). Thus, the heat insulating cover C is supported so as to cover the lower portion of the fuel tank T.
【００１７】 図３、図５及び図７から明らかなように、断熱カバーＣの左側縁には上向きに 突出する前後２本の凸状部２７，２７が車体前後方向に形成され、また右側縁に は上向きに突出する１本の凸状部２８が車体前後方向に形成される。これら凸状 部２７，２７；２８は、断熱カバーＣのサイドフレーム９，１０への取付部近傍 の剛性を高め、その自重による垂れ下がりを防止する。断熱カバーＣの凸状部２ ７，２７；２８の上端は、断熱カバーＣの車体への取付部、即ちボルト２４…， ２５…，２６…の締付部よりも高い位置まで延出している（図５参照）。これに より、燃料タンクＴの下面における広い領域を断熱カバーＣで覆うことが可能と なって断熱効果が向上する。As is apparent from FIGS. 3, 5 and 7, the left and right edges of the heat insulating cover C are formed with two front and rear convex portions 27, 27 projecting upward, and the right and left edges. On the other hand, one convex portion 28 protruding upward is formed in the vehicle front-rear direction. These convex portions 27, 27; 28 increase the rigidity in the vicinity of the mounting portion of the heat insulating cover C to the side frames 9, 10 and prevent the sagging due to its own weight. The upper end of the convex portion 27, 27; 28 of the heat insulating cover C extends to a position higher than the mounting portion of the heat insulating cover C to the vehicle body, that is, the tightening portion of the bolts 24, 25, 26. (See Figure 5). As a result, a wide area on the lower surface of the fuel tank T can be covered with the heat insulating cover C, and the heat insulating effect is improved.
【００１８】 尚、断熱カバーＣの凸状部２７，２７；２８を更に大きく形成すれば、凸状部 ２７，２７；２８が車両の走行方向と平行に形成されていることと相俟って、凸 状部２７，２７；２８に沿って流れる走行風で断熱カバーＣを冷却し、断熱効果 を一層向上させることができる。Incidentally, if the convex portions 27, 27; 28 of the heat insulating cover C are formed to be larger, the convex portions 27, 27; 28 are formed in parallel with the traveling direction of the vehicle. The heat insulating cover C can be cooled by the traveling wind flowing along the convex portions 27, 27; 28, and the heat insulating effect can be further improved.
【００１９】 断熱カバーＣには補強用の３本のビード２９…が車体前後方向に形成される。 これら３本のビード２９…は燃料タンクＴの下半部２に形成した３本のビード２ 2 …下方から嵌合しており、これにより断熱カバーＣと燃料タンクＴとの隙間を 最小限に抑えながら、断熱カバーＣの最小地上高を大きく確保している。Three beads 29 for reinforcement are formed on the heat insulating cover C in the front-rear direction of the vehicle body. These three beads 29 are the three beads 2 formed on the lower half 2 of the fuel tank T. 2 ... Fitting from below, which minimizes the gap between the heat insulating cover C and the fuel tank T, while ensuring a large minimum ground clearance of the heat insulating cover C.
【００２０】 図２〜図４から明らかなように、断熱カバーＣの後部左側縁にはプロテクタ ３０が一体に形成される。プロテクタ３０は上下に湾曲したサイドフレーム９の 下面形状に沿うように形成されており、フィラーパイプ４、ブリーザチューブ５ 、フィードパイプ６、リターンパイプ７及びベントチューブ８の基部を覆って保 護するように機能する。そして、プロテクタ３０の後端に形成した出口開口３０ 1 から、前記フィラーパイプ４及びブリーザチューブ５が後方に延出する。上述 のように、プロテクタ３０を断熱カバーＣと一体に形成することにより、部品点 数を削減してコストを抑えることが可能となる。As is clear from FIGS. 2 to 4, a protector 30 is integrally formed on the rear left side edge of the heat insulating cover C. The protector 30 is formed so as to follow the lower surface shape of the side frame 9 which is curved up and down, and covers and protects the bases of the filler pipe 4, the breather tube 5, the feed pipe 6, the return pipe 7 and the vent tube 8. To function. The outlet opening 30 formed at the rear end of the protector 30. 1 From above, the filler pipe 4 and the breather tube 5 extend rearward. As described above, by forming the protector 30 integrally with the heat insulating cover C, it is possible to reduce the number of parts and reduce the cost.
【００２１】 図３から明らかなように、断熱カバーＣの凸状部１７，１７；１８よりも外側 部分には合計５個の水抜き孔３５…が穿設されており、断熱カバーＣの上面に浸 入しようとした水は前記凸状部１７，１７；１８によって遮られて５個の水抜き 孔３５…から外部に排出される。更に、断熱カバーＣの凸状部１７，１７；１８ よりも内側部分には合計１２個の水抜き孔３１…が穿設されており、断熱カバー Ｃの上面に浸入した水を前記水抜き孔３１…から外部に排出することにより、燃 料タンクＴの錆を防止することができる。As is apparent from FIG. 3, a total of five drainage holes 35 are formed on the outer side of the convex portions 17, 17; 18 of the heat insulating cover C, and the upper surface of the heat insulating cover C is formed. The water that has tried to enter the water is blocked by the convex portions 17, 17; 18 and is discharged to the outside through the five water drain holes 35. Further, a total of twelve water drain holes 31 ... Are bored inside the convex portions 17, 17; 18 of the heat insulating cover C, and water that has penetrated into the upper surface of the heat insulating cover C is drained by the water drain holes. By discharging from 31 to the outside, the rust of the fuel tank T can be prevented.
【００２２】 図３〜図５及び図７から明らかなように、燃料タンクＴの右側面を迂回する排 気管Ｐと断熱カバーＣとの間には、排気管Ｐの熱が燃料タンクＴに及ぶのを防止 するタンクバッフル３２が設けられる。タンクバッフル３２は断面円弧状に形成 された金属板からなり、右側のサイドフレーム１０の下面にボルト３３，３３で 固定される。As is apparent from FIGS. 3 to 5 and 7, the heat of the exhaust pipe P reaches the fuel tank T between the exhaust pipe P that bypasses the right side surface of the fuel tank T and the heat insulating cover C. A tank baffle 32 is provided to prevent this. The tank baffle 32 is made of a metal plate having an arcuate cross section, and is fixed to the lower surface of the right side frame 10 with bolts 33, 33.
【００２３】 前述の構成を備えた本考案の実施例によれば、排気管Ｐからの熱は先ずタンク バッフル３２によって遮断され、更にタンクバッフル３２を通過した熱と路面か らの照り返しとは断熱カバーＣによって遮断され、燃料タンクＴへの伝達が防止 される。断熱カバーＣを通過して燃料タンクＴに伝達された僅かな熱も、その内 部に仕切り板１７によって画成された空間１８…に貯留された燃料に遮断される ため、燃料タンクＴの内部における蒸発燃料の発生を効果的に抑制することがで きる。According to the embodiment of the present invention having the above-described structure, the heat from the exhaust pipe P is first blocked by the tank baffle 32, and the heat passing through the tank baffle 32 and the reflection from the road surface are insulated. It is blocked by the cover C and transmission to the fuel tank T is prevented. Even a slight amount of heat transmitted to the fuel tank T through the heat insulating cover C is cut off by the fuel stored in the space 18 defined by the partition plate 17 inside the fuel tank T. It is possible to effectively suppress the generation of evaporated fuel in the.
【００２４】 また、断熱カバーＣは中央部及び外周部において強固に支持されており、しか も外周部に設けた凸状部１７，１７；１８によって剛性が高められているため、 断熱カバーＣが自己の重量で変形することが防止される。これにより、自動車の 走行中に断熱カバーＣが振動して騒音を発したり、断熱カバーＣが振動による疲 労で破損する等の不具合を確実に回避することができる。Further, the heat insulating cover C is firmly supported in the central portion and the outer peripheral portion, and the rigidity is increased only by the convex portions 17, 17; 18 provided on the outer peripheral portion, so that the heat insulating cover C is It is prevented from being deformed by its own weight. As a result, it is possible to reliably avoid problems such as the heat insulating cover C vibrating and making noise while the vehicle is running, and the heat insulating cover C being damaged by fatigue due to vibration.
【００２５】 図８は燃料タンクＴの内部構造の変形例を示すものである。FIG. 8 shows a modification of the internal structure of the fuel tank T.
