Description

本発明は、燃料タンクを車体に固定するための燃料タンク支持バンドに、制振・防音のために装着されるバンドクッションの構造に関するものである。   The present invention relates to a structure of a band cushion attached to a fuel tank support band for fixing a fuel tank to a vehicle body for vibration suppression and soundproofing.

燃料タンク支持バンドには、従来から下記特許文献１、２に示されたように、ゴム、合成樹脂等の弾性材料からなるクッションを介在することにより、走行中に燃料タンク内で発生する燃料が揺れる音や走行中の振動が車体に伝播し、車内の静粛性が損なわれたり、振動によって燃料タンクが損傷を受けることのないようにしている。
特開２００３−２６７０７４号公報 特開２００６−１１６９９１号公報 Conventionally, as shown in Patent Documents 1 and 2 below, the fuel tank support band is provided with a cushion made of an elastic material such as rubber or synthetic resin, so that the fuel generated in the fuel tank during traveling is present. The swaying sound and vibration during traveling are transmitted to the vehicle body so that the quietness in the vehicle is not lost and the fuel tank is not damaged by the vibration.
JP 2003-267074 A JP 2006-116991 A

ところで、従来の上記バンドクッションは、所期の制振効果を得るために、上面に円形、或いは鉤形の突起が一体成形され、該突起の先端が燃料タンクの表面に接するように装着し、燃料タンク表面との間に空隙が形成されるようにしたものであったが、このような形状は射出成形によらなければ成形できないため、製造コストが高くなると共に、一定長のものしか成形できないという問題があった。また、上記バンドクッションは、装着時に横ズレし易いために、横ズレを防ぐための両面テープを予め貼付しておくこと等の対策を要するという問題もあった。   By the way, in order to obtain the desired vibration damping effect, the conventional band cushion is mounted so that a circular or bowl-shaped protrusion is integrally formed on the upper surface, and the tip of the protrusion is in contact with the surface of the fuel tank. A gap was formed between the surface of the fuel tank and such a shape. However, since such a shape cannot be formed unless it is by injection molding, the manufacturing cost increases and only a certain length can be formed. There was a problem. In addition, since the band cushion is likely to be laterally displaced when worn, there is a problem that it is necessary to take measures such as applying a double-sided tape in advance to prevent lateral displacement.

本発明は上記問題点を解消した新たな構造のバンドクッションを提供しようとするものである。そのために本発明のバンドクッションは、弾性材料を押出し成形することにより横断面が長手方向に等しい帯状に一体成形されるものであって、上面の両側縁寄りに断面形状が末広形の一対の突条部を成形し、下面には両側縁から垂下し内向きに折曲したフック部を成形してなり、該フック部の内側に緊締バンドを装着して燃料タンクを支持したとき前記突条部が該燃料タンクの表面に弾性的に圧着し、該突条部間に空隙が形成されるようにしたことを特徴とする。
また、本発明は上記バンドクッションにおいて、突条部は断面形状を半円形に成形したものであることを特徴とする。 The present invention seeks to provide a band cushion having a new structure that solves the above-mentioned problems. For this purpose, the band cushion of the present invention is integrally formed in a band shape whose cross section is equal to the longitudinal direction by extruding an elastic material, and a pair of protrusions having a divergent cross section near both side edges of the upper surface. When the hook portion is formed on the lower surface and bent inward from the side edges and bent inward, and the elastic band is attached to the inner side of the hook portion to support the fuel tank, the protrusion portion is formed. Is elastically pressure-bonded to the surface of the fuel tank so that a gap is formed between the protrusions.
Further, the present invention is characterized in that, in the above band cushion, the protrusion is formed in a semicircular cross-sectional shape.

本発明のバンドクッションは、押出成形により高い生産性をもって低コストで製造できる。また、燃料タンクの大きさに合わせて切断することで長さも自由にできる。緊締バンドを横ズレするおそれなく容易に装着することができる。高い制振性能・防音性能が維持される。など有益な効果がある。   The band cushion of the present invention can be manufactured by extrusion molding with high productivity and low cost. In addition, the length can be freely set by cutting according to the size of the fuel tank. The tightening band can be easily attached without fear of lateral displacement. High vibration and sound insulation performance is maintained. There are beneficial effects.

次に本発明の実施の形態を図面と共に説明する。図１は本発明に係るバンドクッションの斜視図、図２はその使用状態を示した燃料タンクの側面図である。このバンドクッション１は、ゴム、軟質合成樹脂等の弾性材料を押出し成形することにより横断面が長手方向に等しい帯状に一体成形されるもので、上面の両側縁寄りに断面形状が半円形の一対の突条部２，２を平行に成形し、下面には両側縁から垂下し内向きに折曲した一対のフック部３，３を平行に成形してなる。このバンドクッション１は、燃料タンク４の大きさに応じて適宜長さに切断される。そして、図３に示されるように、フック部３，３の内側に金属製の緊締バンド５の両側縁が収まるように該バンドクッション１の下面に該緊締バンド５を装着し、該緊締バンド５の上面を該バンドクッション１によって被覆すると共に、該緊締バンド５の両端部を車体６にボルト７等で止着する。これにより該燃料タンク４がバンドクッション１を介して緊締バンド５に支持され、該バンドクッション１の突条部２，２が燃料タンク４の表面に弾性的に圧着し、突条部２，２間に空隙８が形成される。   Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a band cushion according to the present invention, and FIG. 2 is a side view of a fuel tank showing a use state thereof. The band cushion 1 is integrally formed in a band shape whose cross section is equal to the longitudinal direction by extruding an elastic material such as rubber and soft synthetic resin, and a pair of semicircular cross sections near the side edges of the upper surface. The protrusions 2 and 2 are formed in parallel, and a pair of hook parts 3 and 3 which are suspended from both side edges and bent inward are formed on the lower surface in parallel. The band cushion 1 is appropriately cut according to the size of the fuel tank 4. Then, as shown in FIG. 3, the tightening band 5 is attached to the lower surface of the band cushion 1 so that both side edges of the metal tightening band 5 fit inside the hook portions 3, 3. Is covered with the band cushion 1 and both ends of the tightening band 5 are fastened to the vehicle body 6 with bolts 7 or the like. As a result, the fuel tank 4 is supported by the tightening band 5 via the band cushion 1, and the protrusions 2, 2 of the band cushion 1 are elastically pressure-bonded to the surface of the fuel tank 4. A gap 8 is formed between them.

このように、燃料タンク４と緊締バンド５との間に弾性材料からなるバンドクッション１が介在し、該バンドクッション１に突条部２，２が成形されていることにより、燃料タンク４との接触面積が小さくなると共に、緊締バンド５を最小限の材料で燃料タンク４の表面から大きく離間させることができるので、燃料タンク４から発する燃料が揺れる音や振動が該バンドクッション１に吸収されて減衰し、緊締バンド５を伝って車体６側に伝播する音・振動を大幅に軽減することができる。   As described above, the band cushion 1 made of an elastic material is interposed between the fuel tank 4 and the tightening band 5, and the protrusions 2 and 2 are formed on the band cushion 1. As the contact area is reduced, the tightening band 5 can be greatly separated from the surface of the fuel tank 4 with a minimum amount of material, so that the vibration and vibration of the fuel emitted from the fuel tank 4 are absorbed by the band cushion 1. The sound and vibration that attenuates and propagates to the vehicle body 6 side through the tightening band 5 can be greatly reduced.

また、このバンドクッション１は、押出し成形により製造されることから、従来の射出成形品と比べて製造コストが大幅に軽減されると共に、燃料タンク４の大きさに合うように適宜長さに切断して使用することができ、常に最適な使用状態を得ることができる。さらには、このバンドクッション１は、フック部３，３の内側に緊締バンド５が装着されるようにしたので、装着時に横ズレするおそれがなく、従来のように両面テープを使用しなくても常に正しく精度よく装着されて燃料タンク４をしっかり支持することができる。このためこのバンドクッション１の構造により、燃料タンクの組み付け不良も防止される。   Further, since the band cushion 1 is manufactured by extrusion molding, the manufacturing cost is greatly reduced as compared with a conventional injection molded product, and the band cushion 1 is cut to an appropriate length so as to match the size of the fuel tank 4. And can always be used in an optimum state. Furthermore, the band cushion 1 is configured such that the tightening band 5 is attached to the inner side of the hook portions 3 and 3, so that there is no risk of lateral displacement at the time of attachment, and a double-sided tape is not used as in the prior art. The fuel tank 4 can be firmly supported at all times by being correctly and accurately mounted. For this reason, the structure of the band cushion 1 prevents the fuel tank from being assembled incorrectly.

なお、突条部２，２の形状は、上記のように半円形にすることのほか、図４に示したように、台形状としてもよい。要するに、突条部２，２を半円形や台形状のような末広状の形状に成形し、該突条部２，２が基部にゆくに従い幅広となるようにすることで、燃料タンク４が弾性材料により常に安定して支持されるようにするのがよい。   In addition, the shape of the protrusions 2 and 2 may be a trapezoid as shown in FIG. 4 in addition to the semicircular shape as described above. In short, the fuel tank 4 is formed by forming the ridges 2 and 2 into a divergent shape such as a semicircular shape or a trapezoidal shape so that the ridges 2 and 2 become wider as they go to the base. It is preferable that the elastic material is always stably supported.
