Abstract
【解決手段】タイヤ内周面に多数の多孔質材料からなる吸音材5をタイヤ周方向に間欠的に配列するように取り付け、吸音材5の数を5〜50個にすると共に、タイヤ周方向に積算した合計長さをタイヤ最大内周長の75%以上にし、かつ吸音材5の間の間隔を吸音材5のタイヤ周方向端部における最大厚さの1倍以上にすると共に、タイヤ最大内周長の15%以下にし、かつ吸音材5をタイヤ周方向に延長する弾性バンド6の内周面及び外周面のいずれか一方に固定し、弾性バンド6を介してタイヤ内周面に取り付けたことを特徴とする。
【選択図】図2
Description
取付け構造:図2
吸音材の形状:幅W:150mm、厚さ:20mm、長さL:180mmで、各隅部を60mm×60mmに面取りした8角形
吸音材の数:9個(間隔Dを約30mmにして配置)
(b)従来例1
取付け構造:図7(b)
吸音材の形状:幅W:150mm、厚さ:20mm、長さL:200mmで、各隅部を60mm×60mmに面取りした8角形
吸音材の数:4個(タイヤ軸に対して90°の角度で均等配置)
(c)従来例2
取付け構造:図7(a)
吸音材の形状:幅W:150mm、厚さ:20mm、周長:1890mmで、連続帯状
吸音材の数:1枚(タイヤ内周面の全周に連続配置)
試験タイヤをドラム試験機の回転ドラムに荷重7.8kNで接圧し、時速80km/hで走行させて、吸音材に損傷が発生するまでの距離を測定した。測定結果は、従来例1の測定値を100とする指数で示した。指数値が大きいほど吸音材の耐久性が優れていることを意味する。
ユニフォミティ−測定機を使用し、試験タイヤを時速100km/hで走行させたときのラジアル・フォース・バリエーション(RFV)の2次成分を測定した。測定結果は、従来例2の測定値を100とする指数で示した。指数値が小さいほど振動性能が優れていることを意味する。
6 弾性バンド
