Description
前記芯材コード層中の補強コードが金属コードであり、かつ、該金属コードが前記芯材コード層の長手方向に対して40〜90°の傾斜角度を有し、
前記螺旋状コード層中の補強コードが、19GPa以上のモジュラスを有する有機繊維コードであり、
前記芯材コード層の幅方向端部における金属コードと、前記螺旋状コード層の幅方向端部における補強コードと、の距離が、前記芯材コード層の金属コードの径の0.2〜20倍であることを特徴とするものである。ここで、モジュラスとは、JIS L 1013に従い、試験温度:25℃、速度:30cm/min、つかみ間隔:250mmで初期引張を行ったときの値である。
図1は、本発明の一好適な実施の形態に係るタイヤ用補強部材の幅方向断面図であり、図2は、本発明の一好適な実施の形態に係るタイヤ用補強部材の補強コード角度を示す概略平面図である。本発明のタイヤ用補強部材1は、少なくとも1層の芯材コード層2と、この芯材コード層2に螺旋状に巻き付けられた、補強コードを有する螺旋状コード層3と、を有する。芯材コード層2および螺旋状コード層3は、補強コードを多数本並行に引きそろえ、この上下に未加硫ゴムを配置して、補強コードをゴム被覆することにより製造される。図示する本発明のタイヤ用補強部材においては、芯材コード層2は1層であるが複数層であってもよい。
本発明のタイヤは、本発明の補強部材1が用いられてなるものであり、乗用車用、トラック・バス用、建設車両用、二輪車用、航空機用、農業用のタイヤが挙げられる。好適には、乗用車用、トラック・バス用および建設車両用のタイヤである。また、本発明のタイヤは、空気入りタイヤ以外に限定されず、ソリッドタイヤや非空気入りタイヤの補強部材としても用いることができる。
図5は、トラック・バス用タイヤの一構成例を示すタイヤ幅方向断面図である。図示するトラック・バスタイヤ20においては、接地部を形成するトレッド部21と、このトレッド部21の両側部に連続してタイヤ半径方向内方へ延びる一対のサイドウォール部22と、各サイドウォール部22の内周側に連続するビード部23と、を備えている。トレッド部21、サイドウォール部22およびビード部23は、一方のビード部23から他方のビード部23にわたってトロイド状に延びる一枚のカーカスプライからなるカーカス24により補強されている。なお、図示するトラック・バス用タイヤ20においては、一対のビード部23にはそれぞれビードコア25が埋設され、カーカス24は、このビードコア25の周りにタイヤ内側から外側に折り返して係止されている。
図7は、建設車両用タイヤの一構成例を示すタイヤ幅方向断面図である。図示する建設車両用タイヤ30においては、接地部を形成するトレッド部31と、このトレッド部31の両側部に連続してタイヤ半径方向内方へ延びる一対のサイドウォール部32と、各サイドウォール部32の内周側に連続するビード部33と、を備えている。トレッド部31、サイドウォール部32およびビード部33は、一方のビード部33から他方のビード部33にわたってトロイド状に延びる一枚のカーカスプライからなるカーカス34により補強されている。なお、図示する建設車両タイヤ30においては、一対のビード部33にはそれぞれビードコア35が埋設され、カーカス34は、このビードコア35の周りにタイヤ内側から外側に折り返して係止されている。
<実施例1〜10および比較例>
1層の芯材コード層に螺旋状コード層を巻き付けて実施例の補強部材を作製した。芯材コード層の補強コードとしては、線径0.33mmのスチールフィラメントを用いた1×3構造のスチールコードを用いた。また、螺旋状コード層の補強コードとしては炭素繊維コードまたはアラミドコードを用いた。補強部材の長手方向に対する芯材コード層のスチールコードの傾斜角度は、表1に示すとおりであり、補強部材の長手方向に対する螺旋状コード層の炭素繊維コードの傾斜角度は20°とした。なお、芯材コード層および螺旋状コード層の打ち込み本数は、34本/50mmとした。
引張剛性の測定は、作製した補強部材を長手方向が引張軸方向になるように引張試験機にチャッキングし、10mm/minの速度で引っ張り、上下のチャック間の中央の標点間距離50mmで変位を測定することにより行った。得られた結果は、比較例を100とする指数にて表した。この値が大きいほど、引張剛性が大きいことを示す。結果を表1に示す。
タイヤ作製前に該当コードの突起を当てる個所に歪ゲージを貼付して、慎重にタイヤを作製し、室内試験にて、正規内圧・荷重にて突起を踏んだ状態で、歪ゲージにより歪を計測して、比較した。
