【発明の詳細な説明】
この発明は、自動車の燃料タンクに係り、特に燃料タン
ク内に設けられるパンフル板の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fuel tank for an automobile, and more particularly to an improvement in a panfur plate provided in a fuel tank.
一般に、自動車の燃料タンク１！−１：、第１図に示す
ように車体Ｂの後部に配設されておシ、この場合、マフ
ラー２が燃料タンクに隣接して設けられることとなる。In general, a car's fuel tank 1! -1: As shown in FIG. 1, the muffler 2 is disposed at the rear of the vehicle body B. In this case, the muffler 2 is disposed adjacent to the fuel tank.
従来この自動車用燃料タンクとしては、第２図及び第３

（例えば１．昭和５５年４月山海堂発行、自動車工学全
書１３巻乗用車の車体）。Conventionally, this fuel tank for automobiles was as shown in Figures 2 and 3.
Upper shell 3 press-formed from a steel plate as shown in the figure
and a lower shell 4 are combined, joined by means such as seam welding, and a panfur plate 5 is provided inside. body).
このバッフル板５は燃料タンク１内に貯蔵されるガソリ
ン等の燃料が、車両の増減速や方向変向に伴なう加速度
で、燃料タンク１内を揺動して音が発生したり、液位が
変化するのを防止するため、燃料タンク内に車幅方向に
鋼製の板材を立設してなるものである。このバッフル板
５は、燃料タンク１のロアシェル４に溶接されており、
このパンフル板５０両端部と、燃料タンク１内壁との間
に間隙６，７を形成して燃料の流路を限定するようにし
ている。即ちパンフル板５は燃料の車体前後方向の移動
を上記流路６．７に限定することによって、燃料の揺動
に伴なう異音や液位の急激な変化を防止するものである
。This baffle plate 5 prevents the fuel such as gasoline stored in the fuel tank 1 from swinging within the fuel tank 1 due to acceleration caused by acceleration, deceleration, or direction change of the vehicle, causing noise or liquid In order to prevent the fuel tank from changing its position, a steel plate is installed vertically inside the fuel tank in the vehicle width direction. This baffle plate 5 is welded to the lower shell 4 of the fuel tank 1,
Gaps 6 and 7 are formed between both ends of the panful plate 50 and the inner wall of the fuel tank 1 to limit the fuel flow path. That is, the panful plate 5 restricts the movement of fuel in the longitudinal direction of the vehicle body to the above-mentioned flow path 6.7, thereby preventing abnormal noises and sudden changes in the liquid level due to the swinging of the fuel.
なお、図中符号８は旋回槽で、燃料の安定的な供給がで
きるように燃料導出管（図示していない）付近の液位の
安定を図っているものである。In addition, the reference numeral 8 in the figure is a swirling tank, which is intended to stabilize the liquid level near the fuel outlet pipe (not shown) so that fuel can be stably supplied.
しかしながらこのような従来の燃料タンクにあっては、
パンフル板５が燃料の揺動を阻止するものであるので、
これには相当量の反力が作用し、パンフル板５と燃料タ
ンク１０ロアシエル４との溶接等は充分強度を持たせる
ものでなければならず、その作業が煩雑となっていた。However, in such conventional fuel tanks,
Since the panful plate 5 prevents the fuel from swinging,
A considerable amount of reaction force acts on this, and the welding between the panful plate 5 and the fuel tank 10 lower shell 4 must have sufficient strength, making the work complicated.
さらに、燃料は、パンフル板５の両端部と燃料タンク１
内壁との間隙６，７のみを流れるものであるから流速が
速くなり、原音が発生し、これに対しても対策を施す必
要があるという不具合がめった。Furthermore, the fuel is distributed between both ends of the panful plate 5 and the fuel tank 1.
Since it flows only through the gaps 6 and 7 between the inner wall and the inner wall, the velocity of the flow becomes high and an original sound is generated, which often causes problems that require countermeasures to be taken.
この考案はこのような不具合に鑑みなされたものであっ
て、バッフル板にかわる反力を少くしてパンフル板とロ
アシェルとの接合を容易にすることができると共に、燃
料の原音の発生を低減させることのできる自動車の燃料
タンクを提供することを目的とする。This idea was developed in view of these problems, and it is possible to reduce the reaction force acting on the baffle plate, making it easier to connect the baffle plate and the lower shell, and reducing the generation of the original fuel noise. The purpose is to provide a fuel tank for automobiles that can be used in various ways.
そしてこの目的は、パンフル板を内装してなる燃料タン
クにおいて、上記パンフル板を多孔質焼結材で構成した
燃料タンクで達成される。This object is achieved in a fuel tank having a panfur plate inside the fuel tank, in which the panfur plate is made of porous sintered material.
次に本発明の一実施例に係る燃料タンクについて説明す
る。Next, a fuel tank according to an embodiment of the present invention will be described.
第４図及び第５図は本実施例に係る燃料タンク９を示し
ており、従来の燃料タンク１と同一の部材には同一の符
号を付している。本実施例においてパンフル板１０は、
多孔質焼結材としてのアルミニウム多孔質焼結板（以下
アルミ焼結板という）で形成されている。4 and 5 show a fuel tank 9 according to this embodiment, and the same members as those in the conventional fuel tank 1 are given the same reference numerals. In this embodiment, the breadboard 10 is
It is formed of an aluminum porous sintered plate (hereinafter referred to as an aluminum sintered plate) as a porous sintered material.
アルミニウム多孔質焼結板は、アルミニウム粉又はアル

結によって金属的な１度をも有している。Aluminum porous sintered plate is made by sintering aluminum powder or aluminum alloy powder under certain conditions and bonding adjacent particles to form a single body. In addition to being a transparent material, it also has metallic properties due to sintering between particles.
本実施例においてパンフル板１０は、従来の、パンフル

燃料タンク９のロアシェル４に溶接して設けられている
。またパンフル板１０の両端部と燃料タンク９内壁との
間には従来と同様に間隙１１．１２が設けられている。In this embodiment, the panful plate 10 has a substantially hat-shaped flat cross-sectional shape similar to the conventional panful plate 5, and a flange portion 13 formed by bending along the longitudinal direction is attached to a fuel tank 9 made of a steel plate. It is welded to the lower shell 4 of the. Also, gaps 11 and 12 are provided between both ends of the panful plate 10 and the inner wall of the fuel tank 9, as in the conventional case.
従って、燃料は第５図矢印に示すようにこの間隙１１．

して熱をパンフル板１０に吸収されて、冷却される。Therefore, fuel flows through this gap 11. as shown by the arrow in FIG.
12 and flows into the swirling tank 8 side, as well as flowing into the swirling tank 8 through a through hole in a panful plate 10 made of a sintered aluminum plate.
flowing into the side. For this reason, the amount of fuel heated by the muffler 2 is reduced, and the fuel heated in the gap 12 between the panful plate 10 and the inner wall of the fuel tank 9 comes into contact with the panful plate 10 and its heat is absorbed by the panful plate 10. , cooled.
パンフル板１０は熱伝導率の良いアルミニウム粉でかつ
多孔質でりるから表面積が太きいため吸熱を効率良く行

、燃料タンク９外壁面から大気中に放散される。また、
燃料の揺動は、従来と同様にこのパンフル板１０で効果

孔を通過する間にその波動エネルギーが吸収され、吸音
材として優れた特性を有するため、たとえ音が発生して
のこのパンフル板１０に吸収され外部には漏出しない。The panful plate 10 is made of aluminum powder with good thermal conductivity and is porous, so it has a large surface area and efficiently absorbs heat. The heat absorbed by the panful plate 10 is transmitted from the lower end flange 13 of the panful plate 10 to the fuel tank 9, and is radiated into the atmosphere from the outer wall surface of the fuel tank 9. Also,
Fluctuation of the fuel is effectively prevented by the panful plate 10 as in the conventional case, and no abnormal noise is generated due to the fluctuation of the fuel. Furthermore, since the amount of fuel passing through the gaps 11 and 12 is small, it does not move rapidly, and since the aluminum sintered material has through holes that communicate three-dimensionally as described above, the sound waves pass through these through holes. The wave energy is absorbed during the passage, and since it has excellent properties as a sound absorbing material, even if sound is generated, it is absorbed by the panful board 10 and does not leak to the outside.
ここで、パンフル板１０を構成するアルミ焼結板は、金

強贋を有するし、移動する燃料の一部を透過するから燃
料の衝突による衝撃は軽減され、パンフル板１ｏとロア
シェル４との取付は構造は従来はど強度を持たせる必要
はなくなる。Here, since the aluminum sintered plate constituting the panful plate 10 has metal strength, it is sufficiently durable as a panful plate, and because it allows part of the moving fuel to pass through, the fuel collides with the aluminum sintered plate. The impact caused by this is reduced, and the structure for attaching the panful plate 1o and the lower shell 4 does not need to have the strength required in the past.
なお本実施例においては、パンフル板は、燃料タンクの

状のパンフル板に適用してもよい。In this embodiment, the case where the panful plate is a single plate disposed in the vehicle width direction on the lower shell of the fuel tank has been described, but the present invention is not limited to this, and panflu plates of other shapes may be used. May be applied to a board.
以上説明したようにこの発明は、車両の燃料タンク内に
配設されるパンフル板を多孔質焼結材で構成するように

要がなく、その取付作業が容易になるといった効果を奏
する。As explained above, this invention uses a porous sintered material to make the panfer plate installed in the fuel tank of a vehicle, which effectively prevents the movement of fuel and eliminates the generation of noise. . In order to prevent the movement of fuel, some of the fuel is allowed to permeate, so the force applied to the baffle plate is reduced, and the installation of the baffle plate and fuel tank does not require a strong structure, making the installation process easier. This has the effect of making it easier.
