本考案はオートバイに搭載する燃料タンクの給油口に関するものである。 The present invention relates to a fuel filler port of a fuel tank mounted on a motorcycle.
【０００２】[0002]
従来オートバイに搭載されている燃料タンクの給油口部分の構造は次のように なつている。即ち図３に示すようにタンク本体１に円形の給油口２が溶接３され 、その給油口２の口元内周に図３に示すキャップ４の鉄の爪５が係合するための カム片６が突設されている。そして、キャップ４は下面に中空の栓体７が設けら れ、栓体７の付け根に円環状のゴムパッキング８が嵌装着され、栓体７内でばね により上方に付勢される爪板の爪５が栓体７の爪穴９から突出されていて、キャ ップ４の開閉時にはキャップ４の爪５がカム片６を摺り、ゴムパッキング８が給 油口２の上面１０を摺るようになつている。 The structure of the filler port of the fuel tank that has been conventionally mounted on motorcycles is as follows. That is, as shown in FIG. 3, a circular oil supply port 2 is welded 3 to the tank body 1, and a cam piece 6 for engaging the iron claw 5 of the cap 4 shown in FIG. 3 with the inner circumference of the base of the oil supply port 2 is welded. Is projected. A hollow plug body 7 is provided on the lower surface of the cap 4, a ring-shaped rubber packing 8 is fitted and attached to the base of the plug body 7, and a claw plate urged upward by a spring in the plug body 7 is provided. The claw 5 is projected from the claw hole 9 of the plug body 7, so that when the cap 4 is opened and closed, the claw 5 of the cap 4 slides on the cam piece 6, and the rubber packing 8 slides on the upper surface 10 of the oil supply port 2. I'm running.

従来からオートバイに搭載される燃料タンクにはタンク本体がアルミニウムで 作られているものと鉄で作られているものとがある。そして溶接加工上から、タ ンク本体がアルミニウム製の場合はアルミニウム製の給油口を溶接し、タンク本 体が鉄製である場合は鉄製の給油口を溶接している。そして、いずれの場合も給 油口と一体に前記カム片が形成されている。ところで、給油口がアルミニウムで あると、それと一体のアルミニウムのカム片にキャップの鉄の爪が摺るので、ど うしてもアルミニウム製のタンクはカム片が早期に摩耗あるいは毀損するという 問題がある。 BACKGROUND ART Fuel tanks that have been conventionally mounted on motorcycles include a tank body made of aluminum and a tank body made of iron. Due to the welding process, if the tank body is made of aluminum, the aluminum filling port is welded, and if the tank body is made of iron, the iron filling port is welded. In any case, the cam piece is formed integrally with the fuel filler port. By the way, if the filler port is made of aluminum, the iron claw of the cap slides on the aluminum cam piece that is integral with the filler port, and in any case, there is a problem that the cam piece will be worn or damaged early in the tank made of aluminum.
【０００４】 そこで本考案はタンク本体が非鉄金属で作られていても、給油口が確実に固着 されており、カム片も早期に摩耗しないようになつているオートバイ用燃料タン クを提供しようとするものである。Therefore, the present invention is intended to provide a fuel tank for a motorcycle in which the fuel filler port is securely fixed and the cam piece is prevented from prematurely wearing even if the tank body is made of non-ferrous metal. To do.

上記目的を達成するために本考案は、従来と同じようにカム片を一体に形成し た鉄の給油内筒をタンク本体と同じ金属で作った外筒に圧入し、しかも外筒より も鉄の給油内筒の頭を少し引っ込めた内外２層に形成し、内外２層に固定鋲を貫 通して打ち込み、外筒をタンク本体に溶接した構成である。 In order to achieve the above object, according to the present invention, an iron refueling inner cylinder integrally formed with a cam piece is press-fitted into an outer cylinder made of the same metal as the tank body as in the conventional case, and more The head of the refueling inner cylinder is formed in two layers, the inner and outer layers being slightly retracted, the fixing studs are pierced into the two layers of the inner and outer layers, and the outer cylinder is welded to the tank body.
【０００６】 タンク本体がアルミニウムで作られているときは、鉄の給油内筒をアルミニウ ムの外筒に圧入し、しかも外筒より給油内筒の頭を少し引っ込め、内外２層に固 定鋲を貫通し打ち込み、アルミニウムの外筒をアルミニウムのタンク本体に溶接 する。When the tank body is made of aluminum, the iron refueling inner cylinder is press-fitted into the aluminum outer cylinder, and the head of the refueling inner cylinder is slightly retracted from the outer cylinder, so that the inner and outer two layers are fixed with tacks. Weld the aluminum outer cylinder to the aluminum tank body.
【０００７】 また、タンク本体がチタンで作られているときは、鉄の給油内筒をチタンの外 筒に圧入し、しかも外筒より給油内筒の頭を少し引っ込め、内外２層に固定鋲を 貫通し打ち込み、チタンの外筒をチタンのタンク本体に溶接する。Further, when the tank body is made of titanium, the iron refueling inner cylinder is press-fitted into the titanium outer cylinder, and the head of the refueling inner cylinder is slightly retracted from the outer cylinder, and fixed to the inner and outer two layers. Weld the titanium outer cylinder to the titanium tank body.

考案の実施の形態について図面を参照して説明する。タンク本体がアルミニウ ムの場合は、アルミニウムの外筒１１の中に、カム片６が一体に形成された鉄の 給油内筒１２が圧入され、外筒１１の上面１３よりも給油内筒１２の頭即ち上面 １４の方が少しｄだけ引っ込んでいる。１５は固定鋲であつて、外筒１１と給油 内筒１２の肉厚を貫通して内外２筒の互いの移動を防いでいる。アルミニウムの 外筒１１がアルミニウムのタンク本体１に溶接１６されている。 また、タンク本体１がチタンの場合は外筒１１をチタンで作り、その外筒１１ 内に給油内筒１２を圧入し、さらに固定鋲１５で固定してから外筒１１をタンク 本体１に溶接するのである。 An embodiment of the invention will be described with reference to the drawings. When the tank body is aluminum, the iron refueling inner cylinder 12 integrally formed with the cam piece 6 is press-fitted into the aluminum outer cylinder 11, and the refueling inner cylinder 12 of the outer cylinder 11 is inserted more than the upper surface 13 of the outer cylinder 11. The head or upper surface 14 is slightly retracted by d. Reference numeral 15 denotes a fixed stud which penetrates the wall thicknesses of the outer cylinder 11 and the refueling inner cylinder 12 to prevent the inner and outer two cylinders from moving relative to each other. An aluminum outer cylinder 11 is welded 16 to the aluminum tank body 1. When the tank body 1 is made of titanium, the outer cylinder 11 is made of titanium, the refueling inner cylinder 12 is press-fit into the outer cylinder 11, and further fixed with the fixing studs 15, and then the outer cylinder 11 is welded to the tank body 1. To do.

タンク本体がアルミニウムやチタンなどのような非鉄金属で作られる場合でも 、そのようなタンク本体と同種の金属の外筒がタンク本体に溶接され、その外筒 に鉄の給油内筒が圧入され、固定鋲で内外２層が互いに移動しないように固定さ れているので、給油口部分における溶接は確実に行われる。また、キャップを開 閉するとき、キャップの鉄の爪が給油内筒のカム片を摺り、キャップのゴムパッ キングが外筒の上面を摺るので早期摩耗がなくなり耐久性が向上する。 Even when the tank body is made of non-ferrous metal such as aluminum or titanium, an outer cylinder made of the same metal as the tank body is welded to the tank body, and the iron refueling inner cylinder is press-fitted into the outer cylinder. Since the inner and outer layers are fixed by the fixed studs so that they do not move relative to each other, welding is reliably performed at the filler port. Further, when the cap is opened and closed, the iron claw of the cap slides on the cam piece of the refueling inner cylinder, and the rubber packing of the cap slides on the upper surface of the outer cylinder, so early wear is eliminated and durability is improved.
