Description

【0001】
【発明の属する技術分野】
本発明は車輛、特にトラックやバス等の車輛に取付ける、使用されない燃料分を減少させた燃料タンクの改良に関する。
【0002】
【従来の技術】
トラックやバス等の車輛においては、フレームを構成する前後方向に配置されたサイドフレームの側方に前後に所定の間隔をおいて2本のブラケットを突出させ、このブラケットによって燃料タンクを支持させ、更にバンドでこのブラケットに緊縛固定するようにしている。
【0003】
この燃料タンクは、搭載時の位置決めや車輛の衝突事故等で車輛に前後方向の衝撃荷重が加わった際の位置ずれを防止して二次災害を防ぐ必要がある。
そのために図4に示すように燃料タンク1の底面1aの車輛の幅方向にブラケット2の両側に配置されるようにビード3,3aを形成し、更にこのブラケット2と燃料タンク1の外周との間を図示しないバンドで緊縛して燃料タンク1を固定したものが提案されている。
【0004】
また、図5に示すように、燃料タンク1の底面1aに凹溝4,4aを形成し、この凹溝4,4a内にブラケット2,2aが嵌合するように支持させている。この構造の燃料タンク1の場合、2本の凹溝4,4aの間に中央膨出部6が、その両側に側部膨出部7,7aが形成されている。そして中央膨出部6の中程にフィードパイプ8の供給口が開口されており、この部分より燃料をエンジンに供給するようになっている。
【0005】
【発明が解決すべき課題】
しかし、前記図4のビード3,3aを形成した燃料タンク1の場合は、ビード3,3aの高さを十分に高くすることができないために、位置決め効果が不十分であると共にブラケット2との係合力が弱く、燃料タンク1に衝撃荷重が作用した際に抜けやずれを防止する効果はあまり期待できない。そこでこれらのビード3,3aの高さを高くすることが考えられるが、燃料タンクのプレス加工上の問題があり、十分な高さのものに形成することができない。
【0006】
前記図4の燃料タンクの構造に比較して、図5に示すように車輛の前後方向に間隔をおいて凹溝4,4aを形成したものは位置決め、ずれ防止の効果は遙かに優れている。しかし、この構造の燃料タンク1においては中央膨出部6の中央にフィードパイプ8の供給口を開口していることから、前記凹溝4,4aの上面ないし底面が堰になって、2つの側部膨出部7,7aに溜まっている燃料は中央膨出部6に流入することができず、消費されない無効残量となる。
【0007】
前記のように、従来の燃料タンクにおいては位置決め効果やずれ防止効果に劣ったり、燃料の無効残量を発生する等の問題があり、改善が求められていた。
本発明は、特に図5に示した燃料タンクの位置決めとずれ防止効果の優れた点を活かしながら、燃料の無効残量を最小限にすることができる燃料タンクを提供することを目的とするものである。
【0008】
【課題を解決する手段】
前記目的を達成するための本発明に係る車輛用燃料タンク10は、車輛のフレームを構成するサイドフレームの横方向に突出して所定の間隔をあけて前後に設けられた2本のブラケット2に配置されてバンドにて該ブラケット2に緊縛固定される燃料タンクにおいて、
【0009】
前記2本のブラケットおよびバンドで支持される位置に前記燃料タンク内側に突出する2本の凹溝11,11aを形成し、この2本の凹溝の上面を結ぶ水平面Pより下方に、該凹溝11,11aの間に形成された中央膨出部12とこの凹溝11,11aの外方に形成された側部膨出部13,13aとをそれぞれ形成し、前記中央膨出部12の底面10aは車輛の前後方向及び幅方向で中央部が最も深く傾斜面が形成され、前記中央膨出部12の中央部にフィードパイプ8の吸入口を臨ませ
記側部膨出部13,13aの底面10aは、車輛の前後方向で前記凹溝11,11aに近い部分が深くなるようにして傾斜する2本の凹溝11,11aの壁面S 1 の段差を大きく形成すると共に周縁部側が浅くなるように周縁部側に向かって上昇する傾斜面pで形成し、かつ前記側部膨出部13,13aの底面10aは車輛の幅方向で中央部を最も深く逆へ字形に傾斜させている。
【0010】
そして図1及び2に示すように前記水平面Pより下方の中央膨出部12の深さと比較して側部膨出部13,13aの深さが浅く形成されている。
本発明に係る車輛用燃料タンク10は、前記のように、燃料タンクの底部に2本の凹溝11,11aを形成して中央膨出部12とその両側に側部膨出部13,13aを形成して、凹溝11,11aの前後方向の前後の壁面S 1 ,S 2 でブラケット2上に燃料タンク10を確実に位置決めして固定することができ、また車輛の前後方向からの衝撃によるブラケットからのズレや外れを防止することができる。特に、側部膨出部13,13aは前記凹溝11,11aに近い部分が深くなるようにして傾斜する2本の凹溝11,11aの壁面S 1 の段差を大きく形成するので、位置決め及び固定の効果が向上する。
【0011】
中央膨出部12の底面10aは車輛の前後方向及び幅方向で中央部が最も深く傾斜面が形成され、中央膨出部12の中央部にフィードパイプ8の吸入口を設け、更に前記側部膨出部13,13aの底面10aは車輛の前後方向で周縁部側が浅くなるように周縁部側に向かって上昇する傾斜面pに形成し、かつ前記水平面Pより下方の中央膨出部12の深さと比較して側部膨出部13,13aの深さが浅く形成されるので、中央膨出部12に溜まる燃料の量に比較して側部膨出部13,13aに溜められる燃料の量が遙に少なく、更にこのタンク10を搭載した車輛の振動や燃料の慣性によって側部膨出部13,13aから中央膨出部12内に燃料が流入するため、使用されないでタンク10内に残留する燃料の量を最小にし、その有効利用量を最大にすることができる。
更に、側部膨出部13,13aの底面10aは車輛の幅方向で中央部を最も深く逆へ字形に傾斜させているので、燃料タンク10の底面の強度を向上することができる。
【0012】
【発明の実施の形態】
次に、図面を参照して本発明の実施の形態を説明する。
図1は燃料タンク10の正面図、図2と同側面図、図3は内部を切開してブラケットと共に描いた斜視図である。
【0013】
この燃料タンク10は、車輛のフレームを構成するサイドフレーム20の側面に沿って横方向に突出して設けた2本(複数本)のブラケット2の上に載置された状態で図示しないバンドによって緊縛固定されている。
【0014】
この燃料タンク10は、下部本体10Aと上部本体10Bとをプレス成形し、この上下の部分をフランジ15で合わせて溶接によって一体化している。そして図1に示すように車輛の前後方向に間隔をおいて形成された凹溝11,11aの上面を結んで形成された水平面Pより下側に中央膨出部12と側部膨出部13,13aが膨出して形成され、この側部膨出部13,13aの下面は、タンク10の周縁方向が浅くなるように傾斜面pで形成されている。
【0015】
図1に示すように前記中央膨出部12は水平面Pより下方の深さが最も深く、従って燃料を収容する量Vが多い。しかし、側部膨出部13,13aは底面が傾斜面pで形成されているので、燃料を収容する量vは少なくなっている。
また、この実施の形態においては、図2に示すように車輛の幅方向の底面10aが平坦ではなく、中央部が最も深い傾斜面K,Kで形成されている。
【0016】
そして図1に示すように中央膨出部12の底面は車輛の前後方向に中央部が最も深くなるように傾斜させ、更に図2に示すように車輛の幅方向に中央部が最も深く傾斜面が形成されている。また、側部膨出部13,13aの底面を図1に示すように車輛の前後方向で、前記中央膨出部12側に向かって傾斜した傾斜面pで形成すると共に、図2に示すように中央部を最も深く逆ヘ字形に形成してこの側部膨出部13,13aに溜まる燃料の量vが少なくなるように配慮している。
【0017】
なお、図2においては側部膨出部13,13aの底面を車輛の幅方向に逆へ字形に傾斜させているが、この構造は必ずしも必要はないが、側部膨出部13,13a内の燃料の量vを最小にし、更にタンク10の底面10aの強度を向上させる意味において採用するのが良い。
【0018】
本発明の燃料タンク10は、前記詳述したように底面10aに2本の凹溝11,11aと、このタンク10の両側に配置される側部膨出部13,13aをを形成することによって、凹溝11,11aの前後の壁面S1 とS2 を、かなり大きく段差を持たせて賦形することが可能となる。
【0019】
従って、燃料タンク10を、その底面10aに形成された凹溝11,11aを、図3に示すように2本のブラケット2上に嵌合して支持させ、そして図示しないバンドによってブラケット2上にタンク10を緊縛固定して設置が完了することになり、燃料タンク10を確実にサイドフレーム20に固定することができることになる。
【0020】
そして図1及び図3に示すように中央膨出部12内の燃料の量Vに比較して側部膨出部13,13a内の燃料の量vは小さい上に、側部膨出部13,13aの底面は外周部に向かって上昇する傾斜面pで形成されていることから、中央膨出部12内の燃料をエンジンに供給することができ、更に側部膨出部13,13a内の燃料は車輛の振動と燃料の慣性に伴って中央膨出部12内に流入することになるので、燃料の残量を最小限にした燃料タンクを提供することができる。
【0021】
なお、前記実施の形態において凹溝11,11aを形成してブラケット2をこれに嵌合支持させているが、このブラケット2とバンドの当たり面の全周または必要な箇所一部に前記凹溝11,11aを形成すると良い。
【0022】
【発明の効果】
本発明は、以上のように底部に2本の凹溝を形成して中央膨出部とその両側に側部膨出部を形成した燃料タンクを、ブラケット上に確実に位置決めして固定することができ、車輛の前後方向から衝撃が加わった際の燃料タンクをブラケットとバンドからの外れやズレを防止することができる。
【0023】
その上に、燃料タンクの底部に溜まる燃料の大部分を使用することができ、その結果、エンジンに供給できない無効燃料を最小限にした燃料の収容効率の良い燃料タンクを提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a fuel tank which is attached to a vehicle, particularly a vehicle such as a truck or a bus, in which unused fuel is reduced.
[0002]
[Prior art]
In vehicles such as trucks and buses, two brackets project at a predetermined interval in the front and rear sides of the side frames arranged in the front-rear direction constituting the frame, and the fuel tank is supported by the brackets. In addition, it is fixed to this bracket with a band.
[0003]
This fuel tank needs to prevent a secondary disaster by preventing displacement when a longitudinal impact load is applied to the vehicle due to positioning at the time of mounting or a vehicle collision accident.
For this purpose, as shown in FIG. 4, beads 3 and 3 a are formed so as to be arranged on both sides of the bracket 2 in the width direction of the vehicle on the bottom surface 1 a of the fuel tank 1, and the bracket 2 and the outer periphery of the fuel tank 1 are There has been proposed one in which the fuel tank 1 is fixed by binding with a band (not shown).
[0004]
Further, as shown in FIG. 5, concave grooves 4 and 4a are formed in the bottom surface 1a of the fuel tank 1, and the brackets 2 and 2a are supported so as to be fitted into the concave grooves 4 and 4a. In the case of the fuel tank 1 having this structure, a central bulging portion 6 is formed between the two concave grooves 4 and 4a, and side bulging portions 7 and 7a are formed on both sides thereof. A supply port of the feed pipe 8 is opened in the middle of the central bulging portion 6, and fuel is supplied to the engine from this portion.
[0005]
[Problems to be Solved by the Invention]
However, in the case of the fuel tank 1 in which the beads 3 and 3a shown in FIG. 4 are formed, the height of the beads 3 and 3a cannot be made sufficiently high. Since the engaging force is weak, the effect of preventing the slipping or slippage when an impact load is applied to the fuel tank 1 cannot be expected. Therefore, it is conceivable to increase the height of these beads 3 and 3a, but there is a problem in the press working of the fuel tank, and it cannot be formed with a sufficiently high height.
[0006]
Compared with the structure of the fuel tank shown in FIG. 4, as shown in FIG. 5, the grooves 4 and 4 a formed at intervals in the front-rear direction of the vehicle are much more effective in positioning and preventing displacement. Yes. However, in the fuel tank 1 having this structure, since the feed port of the feed pipe 8 is opened at the center of the central bulging portion 6, the top surface or the bottom surface of the concave grooves 4, 4a serves as a weir. The fuel accumulated in the side bulging portions 7 and 7a cannot flow into the central bulging portion 6 and becomes an ineffective remaining amount that is not consumed.
[0007]
As described above, the conventional fuel tank has problems such as inferior positioning effect and shift prevention effect, and ineffective fuel remaining amount, and improvement has been demanded.
It is an object of the present invention to provide a fuel tank capable of minimizing the remaining amount of invalid fuel while taking advantage of the excellent effect of positioning and deviation prevention of the fuel tank shown in FIG. It is.
[0008]
[Means for solving the problems]
In order to achieve the above object, a vehicle fuel tank 10 according to the present invention is disposed on two brackets 2 that protrude in the lateral direction of a side frame that constitutes a vehicle frame and that are provided at a predetermined distance from each other. In the fuel tank that is tightly fixed to the bracket 2 with a band,
[0009]
The form two brackets and the two grooves 11,11a which protrude to the fuel tank interior at a position which is supported by the band, below the horizontal plane P which connects the upper surface of the two grooves, the concave The central bulging portion 12 formed between the grooves 11 and 11a and the side bulging portions 13 and 13a formed outside the concave grooves 11 and 11a are respectively formed . The bottom surface 10a has a deepest inclined surface at the center in the vehicle front-rear direction and the width direction, and the inlet of the feed pipe 8 faces the center of the center bulge portion 12 ,
Before Symbol bottom 10a of the side bulging portion 13,13a is, the two grooves 11,11a which is inclined to a portion close to the groove 11,11a in the front-rear direction of the vehicle becomes deep wall S 1 A step is formed with an inclined surface p that rises toward the periphery so that the periphery is shallow , and the bottom surface 10a of the side bulges 13 and 13a has a central portion in the width direction of the vehicle. It is inclined deeply in the reverse hemisphere .
[0010]
As shown in FIGS. 1 and 2 , the side bulging portions 13 and 13a are formed shallower than the central bulging portion 12 below the horizontal plane P.
As described above, the vehicle fuel tank 10 according to the present invention has two concave grooves 11 and 11a formed at the bottom of the fuel tank, and a central bulging portion 12 and side bulging portions 13 and 13a on both sides thereof. And the fuel tank 10 can be reliably positioned and fixed on the bracket 2 by the front and rear wall surfaces S 1 and S 2 in the front and rear direction of the concave grooves 11 and 11a. It is possible to prevent displacement and disengagement from the bracket. In particular, since the side bulging portion 13,13a increasing form a step wall surface S 1 of the two grooves 11, 11a inclined so as to part becomes deeper closer to the groove 11, 11a, positioning and Fixing effect is improved.
[0011]
The bottom surface 10a of the central bulging portion 12 is formed with the deepest inclined surface in the central portion in the vehicle front-rear direction and the width direction, and a suction port for the feed pipe 8 is provided in the central portion of the central bulging portion 12, and the side portion The bottom surface 10a of the bulging portions 13 and 13a is formed on an inclined surface p that rises toward the peripheral edge side so that the peripheral edge side becomes shallow in the longitudinal direction of the vehicle, and the central bulging portion 12 below the horizontal plane P is formed. Since the side bulging portions 13 and 13a are formed shallower than the depth, the amount of fuel stored in the side bulging portions 13 and 13a compared to the amount of fuel stored in the central bulging portion 12 is reduced . Since the amount of fuel is very small and fuel flows into the central bulging portion 12 from the side bulging portions 13 and 13a due to the vibration of the vehicle on which the tank 10 is mounted and the inertia of the fuel, it is not used in the tank 10 without being used. the amount of remaining fuel to minimize its effective usage It can be maximized.
Further, since the bottom surface 10a of the side bulging portions 13 and 13a has the central portion inclined most deeply in an inverted shape in the width direction of the vehicle, the strength of the bottom surface of the fuel tank 10 can be improved.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of the fuel tank 10, the same side view as FIG. 2, and FIG.
[0013]
The fuel tank 10 is bound by a band (not shown) in a state where the fuel tank 10 is placed on two (a plurality of) brackets 2 provided so as to protrude laterally along the side surface of the side frame 20 constituting the vehicle frame. It is fixed.
[0014]
In the fuel tank 10, the lower main body 10A and the upper main body 10B are press-molded, and the upper and lower portions thereof are combined by a flange 15 and integrated by welding. As shown in FIG. 1, a central bulging portion 12 and a side bulging portion 13 are formed below a horizontal plane P formed by connecting upper surfaces of concave grooves 11 and 11a formed at intervals in the longitudinal direction of the vehicle. 13a bulges, and the lower surfaces of the side bulges 13 and 13a are formed with inclined surfaces p so that the peripheral direction of the tank 10 is shallow.
[0015]
As shown in FIG. 1, the central bulging portion 12 has the deepest depth below the horizontal plane P, and therefore has a large amount V of fuel. However, since the side bulging portions 13 and 13a are formed with the inclined surfaces p at the bottom surfaces, the amount v of fuel is reduced.
Further, in this embodiment, as shown in FIG. 2, the bottom surface 10a in the width direction of the vehicle is not flat, and the central portion is formed by the deepest inclined surfaces K and K.
[0016]
As shown in FIG. 1, the bottom surface of the central bulging portion 12 is inclined so that the central portion is deepest in the longitudinal direction of the vehicle, and further, the central portion is deepest in the width direction of the vehicle as shown in FIG. Is formed. Further, as shown in FIG. 2, the bottom surfaces of the side bulging portions 13 and 13a are formed with an inclined surface p inclined toward the central bulging portion 12 in the longitudinal direction of the vehicle as shown in FIG. In addition, the central portion is formed in the deepest reverse H-shape so that the amount of fuel v accumulated in the side bulging portions 13 and 13a is reduced.
[0017]
In FIG. 2, the bottom surfaces of the side bulging portions 13 and 13 a are inclined in a reverse letter shape in the width direction of the vehicle. However, this structure is not necessarily required, but in the side bulging portions 13 and 13 a. This is preferably used in order to minimize the amount of fuel v and to improve the strength of the bottom surface 10a of the tank 10.
[0018]
As described in detail above, the fuel tank 10 of the present invention is formed by forming the two concave grooves 11 and 11a on the bottom surface 10a and the side bulging portions 13 and 13a disposed on both sides of the tank 10. The wall surfaces S 1 and S 2 before and after the concave grooves 11 and 11a can be shaped with a considerably large step.
[0019]
Accordingly, the fuel tank 10 is supported by fitting the concave grooves 11 and 11a formed on the bottom surface 10a onto the two brackets 2 as shown in FIG. 3, and on the bracket 2 by a band (not shown). The installation is completed by tightly fixing the tank 10 and the fuel tank 10 can be reliably fixed to the side frame 20.
[0020]
As shown in FIGS. 1 and 3, the amount of fuel v in the side bulging portions 13 and 13 a is smaller than the amount V of fuel in the central bulging portion 12, and the side bulging portion 13. , 13a is formed with an inclined surface p rising toward the outer peripheral portion, so that the fuel in the central bulging portion 12 can be supplied to the engine, and further in the side bulging portions 13, 13a. This fuel flows into the central bulging portion 12 with the vibration of the vehicle and the inertia of the fuel, so that it is possible to provide a fuel tank in which the remaining amount of fuel is minimized.
[0021]
In the embodiment, the concave grooves 11 and 11a are formed and the bracket 2 is fitted and supported by the concave grooves 11, but the concave groove is formed on the entire circumference of the contact surface of the bracket 2 and the band or at a part of a necessary portion. 11, 11a may be formed.
[0022]
【The invention's effect】
In the present invention, as described above, the fuel tank in which two concave grooves are formed in the bottom portion and the central bulge portion and the side bulge portions are formed on both sides thereof is reliably positioned and fixed on the bracket. It is possible to prevent the fuel tank from being detached from the bracket and the band and displaced when an impact is applied from the front-rear direction of the vehicle.
[0023]
In addition, most of the fuel accumulated at the bottom of the fuel tank can be used, and as a result, a fuel tank with high fuel storage efficiency can be provided in which the ineffective fuel that cannot be supplied to the engine is minimized.
