Description

本発明は、空気入りタイヤに関するものである。   The present invention relates to a pneumatic tire.

自動車のコーナリングの一技法としてドリフト走行がある。ドリフト走行は後輪を横滑りさせながらコーナを旋回する運転技術であり、モータースポーツイベントなどでスモークを発生させることによって視覚的な効果を発揮するようにした空気入りタイヤが知られている。スモークはドラフト走行時にタイヤが空転し路面との間で摩擦することにより発生する。   One technique for car cornering is drift driving. Drifting is a driving technique that turns corners while sliding the rear wheels. Pneumatic tires that produce visual effects by generating smoke at motor sports events are known. Smoke is generated when the tire slips and rubs against the road surface during drafting.

従来、スモークは単純な白色であったが、視覚的効果をより高めるために色つきのスモークを発生させる技術が提案されている。すなわち、特許文献1には、路面との摩擦時に発生する熱によって活性化され、約39〜76×10-6cmの波長と、約39.5〜77×10-13vpsの周波数範囲内で多様なカラーを有するスモークを発生させる昇華性染料を含有するタイヤ用トレッドゴム組成物が開示されている。 Conventionally, smoke is simple white, but a technique for generating colored smoke has been proposed in order to enhance the visual effect. That is, in Patent Document 1, it is activated by heat generated during friction with the road surface, and has a wavelength of about 39 to 76 × 10 −6 cm and a frequency range of about 39.5 to 77 × 10 −13 vps. A tire tread rubber composition containing a sublimable dye that generates smoke having various colors is disclosed.

しかしながら、昇華性染料を含むトレッドゴムを備えた空気入りタイヤは、公道では走行できないという問題がある。また、発生するスモークの色はトレッドゴムに含有させる染料によるため、タイヤ製造後にスモークの色を変更させることはできない。   However, there is a problem that a pneumatic tire including a tread rubber containing a sublimable dye cannot run on a public road. Moreover, since the color of the smoke generated depends on the dye contained in the tread rubber, the color of the smoke cannot be changed after the tire is manufactured.

本発明は、以上の点に鑑みてなされたものであり、ドリフト走行時等にスモークを発生させることができ、また発生するスモークの色を変更することができ、公道での走行も可能な空気入りタイヤを提供することを目的とする。   The present invention has been made in view of the above points, and can generate smoke at the time of drift traveling or the like, can change the color of the generated smoke, and can travel on public roads. An object is to provide a tire entering.

本発明に係る空気入りタイヤは、トレッド面に設けられた複数の取付穴と、昇華性染料を用いて成型され前記複数の取付穴に装着された複数の発煙部材と、を備えたものである。   A pneumatic tire according to the present invention includes a plurality of mounting holes provided in a tread surface, and a plurality of smoke generating members molded using a sublimation dye and mounted in the plurality of mounting holes. .

本発明によれば、タイヤのトレッド面と路面との間に摩擦が生じたとき、トレッド面に装着された発煙部材に含まれる昇華性染料からスモークをさせることができる。該発煙部材はトレッド面に設けられた取付穴に装着されたものであるため、脱着して異なる昇華性染料を含む発煙部材に換えることにより、発生するスモークの色を変更することができる。また、発煙部材を取り外せば、公道での走行も可能である。   ADVANTAGE OF THE INVENTION According to this invention, when friction arises between the tread surface of a tire, and a road surface, it can be made to smoke from the sublimation dye contained in the smoke generation member with which the tread surface was mounted | worn. Since the smoke generating member is mounted in a mounting hole provided in the tread surface, the color of the smoke generated can be changed by replacing the smoke generating member with a different sublimable dye after desorption. Moreover, if the smoke generating member is removed, traveling on a public road is possible.

一実施形態に係る空気入りタイヤのトレッド部の断面図である。It is sectional drawing of the tread part of the pneumatic tire which concerns on one Embodiment.

本実施形態に係る空気入りタイヤにおいて、トレッド面には複数の取付穴が設けられ、該複数の取付穴には、昇華性染料を用いて成型された複数の発煙部材が装着されている。   In the pneumatic tire according to the present embodiment, a plurality of attachment holes are provided in the tread surface, and a plurality of smoke generating members molded using a sublimation dye are attached to the plurality of attachment holes.

図1は、その一例を示したものであり、左右一対のビード部及びサイドウォール部と、両サイドウォール部間に設けられたトレッド部とを備えた空気入りタイヤにおいて、トレッド部10の断面形状を示している。符号12は、一対のビード部間にトロイダル状に延在するカーカス層であり、符号14は、カーカス層12の外周側に配された少なくとも2層のベルト層であり、符号16は、接地面を構成するトレッドゴム部であり、符号18は、ベルト層14とトレッドゴム部16との間に配されたベルト補強層である。トレッド部10には、タイヤ周方向に延びる複数の主溝20などによってトレッドパターンが形成されている。   FIG. 1 shows an example thereof, and in a pneumatic tire including a pair of left and right bead portions and sidewall portions, and a tread portion provided between both sidewall portions, a cross-sectional shape of the tread portion 10 is illustrated. Is shown. Reference numeral 12 denotes a carcass layer extending in a toroidal shape between the pair of bead portions, reference numeral 14 denotes at least two belt layers arranged on the outer peripheral side of the carcass layer 12, and reference numeral 16 denotes a ground plane. The reference numeral 18 denotes a belt reinforcing layer disposed between the belt layer 14 and the tread rubber portion 16. A tread pattern is formed in the tread portion 10 by a plurality of main grooves 20 extending in the tire circumferential direction.

トレッド部10の表面、すなわちトレッド面には、複数の有底の取付穴22が設けられており、各取付穴22に発煙部材24が埋め込まれている。かかる空気入りタイヤは、複数の取付穴22をトレッド面に具備したタイヤを加硫成型し、得られたタイヤの各取付穴22にそれぞれ発煙部材24を打ち込むことにより作製することができる。   A plurality of bottomed mounting holes 22 are provided on the surface of the tread portion 10, that is, the tread surface, and a smoke generating member 24 is embedded in each mounting hole 22. Such a pneumatic tire can be produced by vulcanizing and molding a tire having a plurality of mounting holes 22 on the tread surface, and driving a smoke generating member 24 into each mounting hole 22 of the obtained tire.

発煙部材24は、取付穴22に着脱可能に装着された部材であり、少なくとも上面がトレッド面に露出した状態に取付穴22に装着されるものであれば、その形状等は特に限定されず、例えば円柱状、角柱状などの柱状の他、種々の形状が挙げられる。例えば、スタッドタイヤ(スパイクタイヤ)のスタッドピンのような円柱状の部材として、トレッド面に設けられた複数の取付穴に打ち込む構成を採用してもよい。一例として、発煙部材24は、断面積(トレッド面に平行な面で切断したときの断面積)が10〜200mm2であってもよく、配設数としてはタイヤ1本当たり20〜200個であってもよい。 The smoke generating member 24 is a member that is detachably attached to the attachment hole 22, and the shape and the like thereof are not particularly limited as long as the smoke generation member 24 is attached to the attachment hole 22 in a state where at least the upper surface is exposed on the tread surface. For example, various shapes other than columnar shapes such as a columnar shape and a prismatic shape are exemplified. For example, as a columnar member such as a stud pin of a stud tire (spike tire), a configuration of driving into a plurality of mounting holes provided on the tread surface may be employed. As an example, the smoke generating member 24 may have a cross-sectional area (cross-sectional area when cut by a plane parallel to the tread surface) of 10 to 200 mm 2 , and the number of arrangements is 20 to 200 per tire. There may be.

発煙部材は、昇華性染料を用いて所定形状に成型された部材であり、タイヤが空転し路面との摩擦によって高温となったときに昇華性染料からスモークを発する。   The smoke generating member is a member molded into a predetermined shape using a sublimable dye, and emits smoke from the sublimable dye when the tire runs idle and becomes high temperature due to friction with the road surface.

昇華性染料としては、路面との摩擦時に発生する熱によって活性化されて色付きスモーク(カラースモーク)を発生させる染料を用いることができる。詳細には、タイヤが舗装道路で高速走行しながら空転したときの摩擦によって発生する熱により、スモークを発散させることができるものであればよく、例えば、130℃以上の温度で活性化されてカラースモークを発生することができるものであればよい。可視光の波長は380〜780nmであり、この範囲内の波長の光を発散することでカラースモークを発煙させることができる。   As the sublimation dye, a dye that is activated by heat generated during friction with the road surface to generate colored smoke (color smoke) can be used. In detail, it is sufficient that the smoke can be emitted by heat generated by friction when the tire is idling while traveling at high speed on a paved road. For example, the color is activated at a temperature of 130 ° C. or higher. Any device that can generate smoke is acceptable. The wavelength of visible light is 380 to 780 nm, and color smoke can be smoked by diverging light having a wavelength within this range.

色相は、使用染料によって定まり、例えば、赤色、橙色、黄色、緑色、青色、紫色などのスモークを発生させることができ、発生させるスモークの色は、単色でも、2色以上の色を同時に発生させてもよい。2色以上を同時に用いる場合、1つの発煙部材に2色以上の昇華性染料を用いてもよく、また、2色以上の発煙部材(即ち、色相の異なる昇華性染料を用いた発煙部材)を1本のタイヤに組み合わせて装着してもよい。例えば、トレッド部の幅方向において、色相の異なる発煙部材を装着することにより(詳細には、トレッド部を、車両内側領域と車両外側領域との2領域や、センター領域とメディエート領域とショルダー領域との3領域などというように複数の領域に分けたときに、これら各領域に装着する発煙部材の色相が異なることにより)、2色以上のカラースモークを、ある程度域別可能にしつつ放出させることができ、視覚効果を高めることができる。   The hue is determined by the dye used, and for example, smoke such as red, orange, yellow, green, blue, and purple can be generated. The generated smoke can be a single color or two or more colors simultaneously. May be. When two or more colors are used at the same time, two or more sublimation dyes may be used for one smoke member, or two or more smoke generation members (that is, a smoke generation member using sublimation dyes having different hues) are used. A single tire may be used in combination. For example, by installing smoke generating members having different hues in the width direction of the tread portion (specifically, the tread portion is divided into two regions, a vehicle inner region and a vehicle outer region, a center region, a mediate region, and a shoulder region. When the color is divided into a plurality of areas such as the above three areas, the smoke smoke member mounted in each of these areas has a different hue), so that two or more color smokes can be released while being categorized to some extent. Can enhance the visual effect.

昇華性染料としては、例えば、米国特許第3690971号に開示されたものを用いることができ、ニトロ系、アゾ系、トリフェニルメタン系、キサンタン系、インジゴイド系、キノンイミン系、チアゾール系、アントラキノン系、ナフタル酸誘導体系、ジアミノナフタリン誘導体系、キノリン誘導体系などの各種の昇華性染料が挙げられる。このような昇華性染料としては、例えば、キーストーンアニリン(Keystone Aniline)社の「Smoke Red」、「Smoke Yellow」、「Smoke Blue」などが市販されており、使用することができる。   As the sublimation dye, for example, those disclosed in U.S. Pat. No. 3,690,971 can be used, and nitro, azo, triphenylmethane, xanthan, indigoid, quinoneimine, thiazole, anthraquinone, Various sublimation dyes such as naphthalic acid derivative series, diaminonaphthalene derivative series, quinoline derivative series and the like can be mentioned. As such a sublimable dye, for example, “Smoke Red”, “Smoke Yellow”, “Smoke Blue” and the like by Keystone Aniline are commercially available and can be used.

昇華性染料を用いて発煙部材を成型するには、例えば圧縮成型法を利用することができる。その場合、例えば、(1)昇華性染料をそのまま型に充填した後、圧縮して発煙部材を成型してもよく、(2)昇華性染料にバインダーを混合して、得られた混合物を型に充填し、圧縮して発煙部材を成型してもよい。   In order to mold a smoke generating member using a sublimable dye, for example, a compression molding method can be used. In this case, for example, (1) the sublimation dye may be filled into the mold as it is, and then the smoke generating member may be molded by compression. (2) The binder is mixed with the sublimation dye and the resulting mixture is molded. The smoke generating member may be molded by filling and compressing.

上記(1)の方法であれば、昇華性染料を加熱することなく所定形状に押し固めて発煙部材を成型することができるので、成型時における昇華性染料の昇華を防ぐことができる。上記(2)の方法であれば、バインダーを付与することにより発煙部材の強度を向上することができ、取付穴への取り付け時及び取り外し時における発煙部材の破損を低減することができる。   If it is the method of said (1), since a smoke generating member can be shape | molded by pressing a sublimation dye into a predetermined shape without heating, sublimation of the sublimation dye at the time of shaping | molding can be prevented. If it is the method of said (2), the intensity | strength of a smoke generating member can be improved by providing a binder, and the failure | damage of the smoke generating member at the time of attachment to an attachment hole and removal can be reduced.

バインダーとしては、樹脂や糖類を用いることができる。樹脂としては、例えば、蝋、石油樹脂、ポリエチレン、ポリプロピレン、塩化ビニル樹脂、酢酸ビニル樹脂、スチレン系樹脂、アクリル樹脂、ポリアミド、ポリエステル及びポリカーボネートなどから選択される少なくとも1種である各種熱可塑性樹脂や、フェノール樹脂、エポキシ樹脂、メラミン樹脂、不飽和ポリエステル樹脂及びアルキド樹脂などから選択される少なくとも1種である各種熱硬化性樹脂が挙げられる。バインダーとして樹脂を用いた場合、発煙部材の強度が高く、取付穴への着脱時における破損を低減する効果が高い。糖類としては、単糖類、二糖類、多糖類が挙げられ、例えばデンプン、果糖、砂糖、オリゴ糖、セルロースなどを用いることができる。バインダーとして糖類を用いる場合、水を用いて溶解ないし糊化させつつ昇華性染料と混合した後、乾燥させて圧縮成型することにより、比較的低温で発煙部材を成型することができるので、成型時における昇華性染料の昇華を抑制しやすい。なお、バインダーの量としては、特に限定されず、例えば、昇華性染料100質量部に対して5〜100質量部でもよく、10〜50質量部でもよい。   As the binder, resins and saccharides can be used. Examples of the resin include various thermoplastic resins that are at least one selected from wax, petroleum resin, polyethylene, polypropylene, vinyl chloride resin, vinyl acetate resin, styrenic resin, acrylic resin, polyamide, polyester, polycarbonate, and the like. And various thermosetting resins that are at least one selected from phenol resins, epoxy resins, melamine resins, unsaturated polyester resins, alkyd resins, and the like. When resin is used as the binder, the strength of the smoke generating member is high, and the effect of reducing breakage during attachment / detachment to / from the attachment hole is high. Examples of the saccharide include monosaccharides, disaccharides, and polysaccharides. For example, starch, fructose, sugar, oligosaccharide, and cellulose can be used. When using saccharides as a binder, the fuming member can be molded at a relatively low temperature by mixing with a sublimable dye while dissolving or gelatinizing with water, then drying and compression molding, so at the time of molding It is easy to suppress sublimation of sublimable dyes in The amount of the binder is not particularly limited, and may be, for example, 5 to 100 parts by mass or 10 to 50 parts by mass with respect to 100 parts by mass of the sublimable dye.

発煙部材は、トレッド面の取付穴に着脱可能に装着されるが、取付穴から取り外す際には、発煙部材を破壊せずに取り外してもよく、あるいはまた破壊して取り外してもよい。例えば、上記(1)のように昇華性染料をそのまま圧縮して成型した場合、発煙部材は比較的割れやすいので、かかる割れやすさを利用して、例えばハンマーなどを用いて粉砕することにより、取付穴から発煙部材を取り除いてもよい。一方、上記(2)の場合、特にバインダーとして樹脂を用いて圧縮成型した場合、発煙部材は割れにくいので、破壊せずに発煙部材を取り外しもよく、その場合、取り外した発煙部材は再びタイヤの取付穴に取り付けて利用することができる。   The smoke generating member is detachably attached to the mounting hole on the tread surface. When the smoke generating member is removed from the mounting hole, the smoke generating member may be removed without destroying, or may be broken and removed. For example, when the sublimable dye is compressed and molded as it is as in (1) above, the smoke generating member is relatively easy to break, so by using such ease of cracking, for example, by pulverizing with a hammer or the like, The smoke generating member may be removed from the mounting hole. On the other hand, in the case of (2) above, particularly when compression molding is performed using a resin as a binder, the smoke generating member is difficult to break, so the smoke generating member may be removed without breaking, and in that case, the removed smoke generating member is again attached to the tire. It can be used by attaching to the mounting hole.

以上説明した本実施形態に係る空気入りタイヤによれば、例えばドリフト走行などでタイヤを空転させたときに、路面との摩擦による熱で、トレッド面に装着された発煙部材からカラースモークを発生させることができ、モータースポーツイベントなどにおいて視覚的な効果を高めることができる。かかる発煙部材はトレッド面に設けられた取付穴に着脱可能に装着されており、異なる色相の昇華性染料を含む発煙部材に取り替えることができるので、発生するスモークの色を変更することができる。また、モータースポーツイベントなどでの使用後には、発煙部材を取り外すことにより公道での走行も可能である。   According to the pneumatic tire according to the present embodiment described above, for example, when the tire is idled during drift running, color smoke is generated from the smoke generating member attached to the tread surface by heat generated by friction with the road surface. Can enhance visual effects in motor sports events. Such a smoke generating member is detachably mounted in a mounting hole provided in the tread surface, and can be replaced with a smoke generating member containing a sublimable dye having a different hue, so that the color of smoke generated can be changed. In addition, after use at a motor sports event or the like, traveling on a public road is possible by removing the smoke generating member.

以下、本発明を実施例によって更に具体的に説明するが、本発明はこれら実施例に限定されるものではない。   EXAMPLES Hereinafter, although an Example demonstrates this invention further more concretely, this invention is not limited to these Examples.

・第4走行:第3走行後の実施例1〜3のタイヤの発煙部材4〜6を取り除いた後、取付穴に発煙部材を装着せずに、サーキットにて、80km直進走行から急旋回し、タイヤを空転させた。そのタイヤ空転時に発生するスモークの色を目視で観察した。
The conditions of the tire running test are as follows.
-1st driving | running | working: As shown in following Table 1, in the tire of the comparative example 1 and Examples 1-3, the smoke generation member was not mounted | worn to the attachment hole. On the circuit, he made a sudden turn from running straight for 80km and made the tire idle. The color of the smoke generated during the tire idling was visually observed.
Second run: As shown in Table 1 below, the smoke generating members 1 to 3 were mounted in the mounting holes of the tread portions of the tires of Examples 1 to 3. Next, on the circuit, the vehicle made a sudden turn from a straight travel of 80 km, and the tire was idled. The color of the smoke generated during the tire idling was visually observed.
Third travel: The smoke generating members 1 to 3 of the tires of Examples 1 to 3 after the second travel were removed, and the smoke generating members 4 to 6 were installed in the mounting holes as shown in Table 1. Next, on the circuit, the vehicle made a sudden turn from a straight travel of 80 km, and the tire was idled. The color of the smoke generated during the tire idling was visually observed.
・ Fourth travel: After removing the smoke generating members 4 to 6 of the tires of Examples 1 to 3 after the third travel, without turning the smoke generating member in the mounting hole, the vehicle suddenly turned from 80 km straight traveling on the circuit. , The tire was idled. The color of the smoke generated during the tire idling was visually observed.

結果は表1に示す通りであり、トレッド面に昇華性染料のない比較例1に対し、比較例2では赤色のスモークを発生させることができたが、第1〜第4の全ての走行で赤色のみであり、色の変更はできなかった。これに対し、実施例1〜3であると、第1走行では白色のスモークであったのを、発煙部材を取り付けることで第2走行では赤色のスモークを発生させることができ、更に発煙部材を取り替えることで第3走行では黄色のスモークを発生させることができた。また、第4走行では再び発煙部材を取り外したことにより白色のスモークを発生させることができ、公道での走行も可能なものにすることができた。   The results are as shown in Table 1. Compared with Comparative Example 1 having no sublimable dye on the tread surface, in Comparative Example 2, it was possible to generate red smoke, but in all the first to fourth runnings Only red, and the color could not be changed. On the other hand, in the first to third embodiments, the white smoke was generated in the first traveling, and the smoke member was attached to generate the red smoke in the second traveling. By replacing it, it was possible to generate yellow smoke in the third run. Moreover, in the 4th driving | running | working, it was able to generate | occur | produce white smoke by removing a smoke generation member again, and was able to make driving | running | working on a public road possible.
