Description

路面が濡れている時あるいは降雨時に、自動車の走行によりタイヤの後方に水しぶきが生じて飛散し、撥ね上げて自動車の後部を泥まみれにすると共に、後方に拡散して後方周辺を汚染する。本発明は、このような自動車のタイヤの周囲に設けてタイヤの水しぶきや泥などの飛散物の拡散を防止する拡散抑制装置、特にトラックやトレーラー等の運搬車両のタイヤの周囲の拡散抑制装置に関する。   When the road surface is wet or when it rains, water splashes behind the tires due to the running of the car, splashes it up, makes the rear part of the car muddy, and diffuses backward to contaminate the rear periphery. The present invention relates to a diffusion suppression device that is provided around the tire of such an automobile and prevents the dispersion of scattered matter such as water spray and mud of the tire, and more particularly to a diffusion suppression device around the tire of a transport vehicle such as a truck or a trailer. .

通常、自動車の車輪のタイヤハウスにフェンダーおよびフェンダー後部下側のゴム製泥よけが取り付けられ、このタイヤハウスのフェンダーとゴム製泥よけによりタイヤから撥ね上げられる水しぶきや泥を抑えている。ところでトラック等の運搬車両はタイヤ径が大きく幅広であり、さらに複数のタイヤが隣接して配設されている。このため、従来のタイヤハウスや泥よけでは水しぶきを抑える効果は十分でなく、水しぶきが後続車や対向車の運転妨害になっている。   Usually, rubber tire mudguards on the fender and the rear lower side of the fender are attached to the tire house of the wheel of an automobile, and the splash and mud that are repelled from the tire by the fender and rubber mudguard of the tire house are suppressed. By the way, a transport vehicle such as a truck has a large tire diameter and is wide, and a plurality of tires are arranged adjacent to each other. For this reason, conventional tire houses and mudguards do not have sufficient effects of suppressing splashing, and the splashing hinders driving of the following vehicle and oncoming vehicle.

この走行車両のタイヤによって撥ね上げる水しぶきを防止するための水しぶき止めシステムは、主として撥ね上げられる水の霧状化および飛散を軽減するシステムである。この水しぶき止めシステムは、しぶき止め装置の他に、泥よけ、レインフラップ、バランスからなっている。このうち、しぶき止め装置は空気/水分離具と霧状の水しぶきをための水しぶきのエネルギー吸収具からなっている。泥よけは、走行中にタイヤから撥ね上げられる水を防ぎ、撥ね水の方向を路面の方にすることを目的とした剛性部品または半剛性部品からなる。この泥よけは、通常はボディー部品や荷台の下方部品などの部品と一体化されているか、一部が一体化されている。レインフラップは、シャーシーもしくは積載面の下方、または泥よけ上にホイール後方に対して垂直に取り付けたフレキシブルな部品である。このレインフラップは路上の小さいもの、とりわけ小石がタイヤに付き、上方または横方向に飛ぶことによって路上にいる人に当たって危害を加えることを軽減する。   The anti-splash system for preventing the splash of water from the tires of the traveling vehicle is a system that mainly reduces the atomization and splashing of the splashed water. In addition to the anti-splash device, this anti-splash system consists of mudguards, rear-infrared, and balance. Of these, the anti-splash device comprises an air / water separator and a spray energy absorber for mist-like spray. Mudguard consists of a rigid or semi-rigid component intended to prevent the water splashed from the tires during travel and to direct the splash water toward the road surface. This mudguard is usually integrated with a part such as a body part or a lower part of the loading platform, or partly integrated. A lainup is a flexible part mounted perpendicular to the rear of the wheel below the chassis or loading surface or on the mudguard. This lean-up reduces the impact of small things on the road, especially pebbles, on the tires and hitting people on the road by flying upwards or sideways.

このようなトラック等の運搬車両の水しぶきの撥ね上げおよび飛散を防止するために、種々の水しぶきの飛散防止装置が開発されている。例えば、表面に人工芝のような表面形状の突起物を植生した泥よけがあるが、これは漫然と突起物が設けられており、水しぶきには効果はあるが、泥などの飛散には効果が十分でなかった。また、降雪時に、この装置に雪が凍りつき重さで走行中に凍った雪の固まりや雪が凍結した飛散防止装置自体が脱落する危険があった。   In order to prevent such splashing and splashing of transport vehicles such as trucks, various splashing prevention devices have been developed. For example, there are mudguards with vegetation with surface shapes such as artificial turf on the surface, but this is loosely provided with projections and is effective for splashing, but it is effective for scattering mud etc. It was not enough. In addition, during snowfall, there is a risk that the snow freezes on this device and the snow mass frozen during traveling and the scattering prevention device itself that snow has fallen fall off.

このためこれら装置は使用目的が雨の日に限られ、晴天時の路面の飛散物の拡散を防止することは十分にできなかった。さらに、突起物の間に上下に間隔を適宜あけて排水リブを配して誘導し、さらに断面三角形状のネットで覆って撥ね上げられた水しぶきを通過し易くすると共に戻りにくくし、かつ風圧でめくり上げられにくくした構造の大型トラック用のスプラッシュ減少装置が市販されている。さらに従来のタイヤの周囲のフェンダーの表面やフェンダーの後部に取り付けて使用する弱化装置と誘導溝からなる泥よけ装置が開発されている(例えば、特許文献1、非特許文献1参照。)。これは誘導溝により撥ね水を一定箇所に集めて流下させるものであり、雨水の水しぶき防止の点で優れている。しかし、この泥よけ装置は、斜め上方に例えば垂直面の下方から上方に125度付近に向けた多段の羽根板を設けているが、この上方に向けた羽根板を有する泥よけ装置は水しぶきの弱化効果は十分に得られるが、飛散物を拡散する効果はほぼ無いことが判明した。すなわち、これ等の先行技術の泥よけや水しぶき防止装置では、路面からの種々の飛散物をより効果的に捕捉しなければならない問題がある。さらに装置の清掃を容易とする問題があった。   For this reason, these devices were used only on rainy days, and it was not possible to sufficiently prevent the scattering of scattered objects on the road surface in fine weather. In addition, the drainage ribs are arranged with an appropriate space between the protrusions in the vertical direction and guided, and the splashes covered with the triangular cross-section net are made to easily pass through, making it difficult to return, and wind pressure. Splash reduction devices for heavy trucks that are difficult to turn up are commercially available. Furthermore, a mudguard device has been developed that includes a weakening device and a guide groove that are attached to the surface of the fender around the conventional tire and the rear of the fender and used (see, for example, Patent Document 1 and Non-Patent Document 1). This is to collect splashing water at a certain location by the guide groove and to flow down, and is excellent in preventing splashing of rainwater. However, this mudguard device is provided with a multi-stage vane obliquely upward, for example, from the lower part of the vertical plane to the vicinity of about 125 degrees. It was found that the effect of weakening the splashing can be obtained sufficiently, but there is almost no effect of diffusing the scattered matter. That is, in these prior art mudguards and splash prevention devices, there is a problem that various scattered objects from the road surface must be captured more effectively. Furthermore, there is a problem that the apparatus can be easily cleaned.

本発明が解決しようとする課題は、上記の先行技術の問題を解決することであり、自動車などの車両からの再飛散物を抑制することができ、これらに加えて、雪が付着して落下することを解消し、雨の日の視界の確保に優れ、追突事故の発生を未然に防止でき、さらに全天候に対応できるなど沿道の環境に優しい自動車などの車両の拡散防止装置を提供することである。   The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, which can suppress re-scattered objects from vehicles such as automobiles, and in addition to these, snow adheres and falls. This is to provide a vehicle diffusion prevention device for roadside environment-friendly vehicles such as roadside environment-friendly vehicles, such as excellent visibility of rainy days, prevention of rear-end collisions, and compatibility with all weather conditions. .

上記の課題を解決するための本発明の手段は、表面に水平方向かつ斜め下方に突出する薄肉の羽根板を多段に配設してなる矩形本体からなる合成ゴム又は合成樹脂の平板と、該平板の両側部に垂直方向の全長にわたる開口部を有する円管からなる縦方向導管を立設し、該縦方向導管の開口部に多段の薄肉の羽根板を有する該平板の左右の垂直端部を挿着したことを特徴とする車両のタイヤの水しぶきや泥などの飛散物の拡散抑制装置である。   The means of the present invention for solving the above-mentioned problems is a synthetic rubber or synthetic resin flat plate made of a rectangular main body formed by arranging thin blades that protrude horizontally and obliquely downward on the surface in a multistage manner, A vertical pipe made of a circular pipe having an opening extending over the entire length in the vertical direction on both sides of the flat plate, and left and right vertical ends of the flat plate having multistage thin blades at the opening of the vertical pipe This is a device for suppressing the dispersion of scattered matter such as water spray and mud of a vehicle tire.

さらに、平板の表面に水平方向かつ斜め下方に突出する薄肉の羽根板は、該平板の下向き面に対する羽根板の突出角度を30〜45度とすることを特徴とする請求項1の手段の車両のタイヤの水しぶきや泥などの飛散物の拡散抑制装置である。   2. The vehicle according to claim 1, wherein the thin blades projecting horizontally and obliquely downward on the surface of the flat plate have a blade projection angle of 30 to 45 degrees with respect to the downward surface of the flat plate. This is a device for suppressing the dispersion of scattered matter such as water spray and mud.

さらに、平板の表面に水平方向かつ斜め下方に突出する薄肉の羽根板は、先端が下方に向いた断面円弧状からなることを特徴とする請求項1または2の手段の車両のタイヤの水しぶきや泥などの飛散物の拡散抑制装置である。   Further, the thin slats projecting horizontally and obliquely downward on the surface of the flat plate have a circular arc shape whose tip is directed downwards. It is a device for suppressing the diffusion of scattered matter such as mud.

本発明の飛散物の拡散抑制装置は、路面から走行自動車のタイヤにより撥ね上げられる水しぶきを効率よく集め、さらに装置から発散物となって再飛散することを抑制することで後方の視界を良好とし、追突事故の発生を未然に防止するなど、優れた効果を奏するものである。   The scattered matter diffusion suppressing device of the present invention efficiently collects splashes splashed by the tire of a traveling vehicle from the road surface, and further improves the rear field of view by suppressing re-scattering as a diverging material from the device. It has excellent effects such as preventing the occurrence of rear-end collisions.

本発明を実施するための最良の形態を図面を参照して説明する。図2は車両1の走行時における回転するタイヤ2の周辺の空気の流れを表したものである。タイヤ2により路面3から巻き上げられる風Aと走行により生じる風Bがポイント4の周辺で互いに激しく衝突し、風Cとなって車両1の外側サイドへ勢いよく噴出している。この風Cが様々の飛散物を周囲の環境に拡散させる下人となっている。   The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 2 shows the air flow around the rotating tire 2 when the vehicle 1 is traveling. The wind A that is wound up from the road surface 3 by the tire 2 and the wind B that is generated by the traveling collide violently around the point 4, and the wind C is vigorously ejected to the outer side of the vehicle 1. This wind C is a genius that diffuses various scattered objects into the surrounding environment.

そこで図3に示すように、タイヤ2により路面3から巻き上げられる風Aの要素のみを取り出し空気の流れを調べたところ、ゴム製の泥よけ5の内面やフェンダー6の内面に反射するものの、図2のように風Cを生じることは無かった。   Therefore, as shown in FIG. 3, when only the element of the wind A wound up from the road surface 3 by the tire 2 was taken out and the flow of the air was examined, it reflected on the inner surface of the rubber mudguard 5 and the inner surface of the fender 6, There was no wind C as shown in FIG.

一方、図4に示すように、車両1の走行時に生じる風B要素のみを取り出し空気の流れを調べたところ、タイヤ2の上面やフェンダー6の内面に反射するものの、やはり図2のように風Cを生じることは無かった。   On the other hand, as shown in FIG. 4, when only the wind B element generated when the vehicle 1 travels is taken out and the flow of air is examined, it is reflected on the upper surface of the tire 2 and the inner surface of the fender 6. C was not generated.

このことから、タイヤ2により路面3から巻き上げられる風Aもしくは走行により生じる風Bのどちらかの要素を抑えれば、風Cは抑えられることになる。   From this, if either element of the wind A wound up from the road surface 3 by the tire 2 or the wind B generated by traveling is suppressed, the wind C is suppressed.

そこで、図5に示すように、泥よけ5の内側とフェンダー6の後部のフェンダー6aの内面に本発明の水しぶきや泥などの飛散物の拡散抑制装置7を取り付けることで、タイヤ2により路面3から巻き上げられる風Aを受け止め、走行により生じる風Bをより流れやすくすることで、これらの風の衝突による側部後方への風Cの発生を抑制することができることとなる。   Therefore, as shown in FIG. 5, by attaching the diffusion suppressing device 7 for splashes and mud of the present invention to the inner surface of the mudguard 5 and the inner surface of the fender 6 a at the rear of the fender 6, By receiving the wind A that is wound up from 3 and making the wind B generated by traveling easier to flow, the generation of the wind C to the rear side due to the collision of these winds can be suppressed.

すなわち、図1に示すように、拡散抑制装置7において羽根板8の形状の先端9を下向きかつ内側に突出させることで、風Aをより受け止め易く、かつ、風Bの流れには風Aと緩衝しにくい形状とし、風Aの流れの向きを風Bと同一方向とすることができ、図2に示すポイント4での衝突を抑えている。このようにして確実に受け止めた風Aを拡散抑制装置7の両端に備えられた円管からなる縦方向導管10の排出溝12で下方の路面3に排出する。このように拡散抑制装置7の左右に設けられた2カ所の縦方向導管10の排出溝12のみに水しぶきや泥は排出されることとなる。   That is, as shown in FIG. 1, in the diffusion suppressing device 7, the tip 9 in the shape of the blade 8 protrudes downward and inward, so that the wind A can be received more easily, and the flow of the wind B The shape is difficult to buffer, and the direction of the flow of the wind A can be the same as the direction of the wind B, and the collision at the point 4 shown in FIG. 2 is suppressed. The wind A reliably received in this way is discharged to the lower road surface 3 through the discharge grooves 12 of the longitudinal conduit 10 formed of circular pipes provided at both ends of the diffusion suppressing device 7. In this way, the spray and mud are discharged only into the discharge grooves 12 of the two longitudinal conduits 10 provided on the left and right of the diffusion suppressing device 7.

さらに、拡散抑制装置7の羽根板8の先端9の突出形状の角度αについて、図7による試験装置により図6に示す最適の角度αを求めた。図6の(a)に示す断面形状の羽根板8の先端を下方に向けて持つ平板13において、図6の(b)に示すように平板13の下向きからの各羽根板8の角度をαとし、角度αを0〜180度と変化させて羽根板8の角度αと水の拡散率の関係を調べた。試験方法は、図7に示す欧州共同体部品認証試験に基づくものとし、高圧ブラストマシン19の噴射装置20にて、200μmの砂粒子を減圧弁21で監視して2kg/mm3の噴射圧により、全量4kgの噴射量として可動式の羽根板8を有する750mm×500mmの拡散抑制装置7のテスト板22に定格噴射した。 Furthermore, the optimum angle α shown in FIG. 6 was obtained for the angle α of the protruding shape of the tip 9 of the blade 8 of the diffusion suppressing device 7 by the test device shown in FIG. In the flat plate 13 having the tip of the blade 8 having the cross-sectional shape shown in FIG. 6A facing downward, the angle of each blade 8 from the downward direction of the flat plate 13 as shown in FIG. The angle α was changed from 0 to 180 degrees, and the relationship between the angle α of the blade 8 and the water diffusivity was examined. The test method is based on the European Community part certification test shown in FIG. 7, and the 200 μm sand particles are monitored by the pressure reducing valve 21 with the injection device 20 of the high pressure blast machine 19 and the injection pressure of 2 kg / mm 3 is used. Rated injection was performed on the test plate 22 of the diffusion suppressing device 7 of 750 mm × 500 mm having the movable vane plate 8 as a total injection amount of 4 kg.

図7において、噴射した粒子をすべて計量器23で回収すると飛散率は0%とする。噴霧前の砂の質量Q1とテスト板が吸収した砂の質量Q2により以下の式(1)により飛散率SP(%)を求めた。   In FIG. 7, when all the ejected particles are collected by the measuring instrument 23, the scattering rate is 0%. The scattering rate SP (%) was determined by the following equation (1) from the mass Q1 of sand before spraying and the mass Q2 of sand absorbed by the test plate.

SP(%)=100・(Q1−Q2)/Q1………(1)   SP (%) = 100 · (Q1-Q2) / Q1 (1)

この結果を表1および図8に示す。   The results are shown in Table 1 and FIG.

Figure 2005289230
Figure 2005289230

以上の試験の結果、羽根板8の角度αが45度において、飛散率42.1%で最も少なく効率がよかった。そして従来の装置は羽根板8の角度αを125度付近としていたが、この角度では十分な効果が得られなかったことが判明した。   As a result of the above test, when the angle α of the blade 8 was 45 degrees, the scattering rate was 42.1% and the efficiency was the lowest. In the conventional apparatus, the angle α of the blade plate 8 is set to around 125 degrees, but it has been found that a sufficient effect cannot be obtained at this angle.

そこで本発明は、平板13の表面に水平方向かつ斜め下方に突出する薄肉の羽根板8を多段に配設してなる矩形本体からなる平板13と、該平板13の両側部に垂直方向の全長にわたる開口部11を有する円管からなる縦方向導管10を立設し、該縦方向導管10の開口部11に該矩形本体の平板13および多段の薄肉の羽根板8の左右の開口部11の垂直端部18を挿着して該縦方向導管10としたことを特徴とする車両1のタイヤ2から走行中に発生する水しぶきや泥などの飛散物の拡散抑制装置7であり、これらはいずれも合成ゴム又は合成樹脂から形成している。   Therefore, the present invention provides a flat plate 13 composed of a rectangular main body in which thin blades 8 that protrude horizontally and obliquely downward are provided on the surface of the flat plate 13 and the total length in the vertical direction on both sides of the flat plate 13. A vertical pipe 10 composed of a circular pipe having an opening 11 extending up and down is provided, and the flat plate 13 of the rectangular main body and the left and right openings 11 of the multistage thin blades 8 are formed in the opening 11 of the vertical pipe 10. It is a diffusion suppression device 7 for splashed matter such as splashes and mud generated during traveling from the tire 2 of the vehicle 1, characterized in that the vertical end portion 18 is inserted into the longitudinal conduit 10. Is also formed from synthetic rubber or synthetic resin.

さらに、上記の構成の拡散抑制装置7の平板13の表面に形成の水平方向かつ斜め下方に突出する薄肉の羽根板8は、この平板13の下向き面に対する羽根板8の突出する角度αを30〜45度とする。   Furthermore, the thin blade 8 that projects horizontally and obliquely downward on the surface of the flat plate 13 of the diffusion suppressing device 7 having the above-described configuration has an angle α at which the blade 8 protrudes with respect to the downward surface of the flat plate 30 by 30. -45 degrees.

さらに、上記の構成の拡散抑制装置7の平板13の表面に水平方向かつ斜め下方に突出する薄肉の羽根板8は、先端9が下方に向いた断面円弧状からなるものである。   Further, the thin blade 8 that projects horizontally and obliquely downward on the surface of the flat plate 13 of the diffusion suppressing device 7 having the above-described configuration has a circular arc shape with the tip 9 facing downward.

図9に示すように、円弧状に斜め下向きに突出し、先端9を突出付け根から45度の角度とする肉厚2.5mmで、高さ11mm、幅13mmの羽根板8を20mm間隔で多段に設けた長さ441mmの基本単位となる平板13を合成ゴムから形成する。平板13の部分の厚みは3mmとする。この平板13の上端14および下端16の両端部には互いに嵌合する係合凹部15と係合突出部17を設けることで平板13の長さを延長可能な嵌合部としている。平板13の横幅は車両1のタイヤ2の幅に合わせたものとする。この平板8を車両1のフェンダー6に装着するときは適宜リベット等により係止する。平板13の縦方向端部には縦方向導管10が嵌合する
図10に縦方向導管10の横断面図を示す。
As shown in FIG. 9, the blades 8 projecting obliquely downward in an arc shape and having a tip 9 at a 45-degree angle from the projecting root and having a thickness of 2.5 mm, a height of 11 mm, and a width of 13 mm are multi-staged at intervals of 20 mm. The flat plate 13 serving as a basic unit having a length of 441 mm is formed from synthetic rubber. The thickness of the portion of the flat plate 13 is 3 mm. By providing engagement recesses 15 and engagement protrusions 17 that fit each other at both ends of the upper end 14 and the lower end 16 of the flat plate 13, the length of the flat plate 13 can be extended. The lateral width of the flat plate 13 is set to match the width of the tire 2 of the vehicle 1. When this flat plate 8 is mounted on the fender 6 of the vehicle 1, it is locked with a rivet or the like as appropriate. The longitudinal conduit 10 is fitted to the longitudinal end portion of the flat plate 13. FIG. 10 shows a cross-sectional view of the longitudinal conduit 10.
