Title (EN) PNEUMATIC TIRE
(FR) PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract: front page image
(EN)A pneumatic tire (1) having, on its surface, turbulent flow generating projections having sharp edges. The tire (1) satisfies the relationships of 0.015 ≤ H/√R ≤ 0.64, 1.0 ≤ p/H ≤ 50.0, 0.1 ≤ H/e ≤ 3.0, 1.0 ≤ L/H ≤ 50.0, 1.0 ≤ (p-w)/w ≤ 100.0, with R the radius of the tire, H the maximum height of a projection, p the circumferential distance between adjacent projections, e the radial distance between adjacent projections, L the radial length of the projection, and A the circumferential length of the projection.
(FR)L'invention concerne un pneumatique (1) présentant, sur sa surface, des parties saillantes générant un écoulement turbulent et dotées de bords tranchants. Le pneu (1) satisfait aux relations de 0,015 ≤ H/√R ≤ 0,64, 1,0 ≤ p/H ≤ 50,0, 0,1 ≤ H/e ≤ 3,0, 1,0 ≤ L/H ≤ 50,0, 1,0 ≤ (p-w)/w ≤ 100,0, R étant le rayon du pneu, H la hauteur maximale d'une partie saillante, p la distance circonférentielle entre des parties saillantes adjacentes, e la distance radiale entre des parties saillantes adjacentes, L la longueur radiale de la partie saillante, et A la longueur circonférentielle de la partie saillante.
(JA) 本発明に係る空気入りタイヤ1は、鋭利なエッジ部が形成される乱流発生用突起をタイヤ表面に備え、タイヤ半径を“R”、突起最大高さを“H”、突起周方向間隔を“p”、突起径方向間隔を“e”、突起径方向長さを“L”、突起周方向長さを“A”としたときに、 0.015≦H/√R≦0.64 、かつ、 1.0≦p/H≦50.0 、 0.1≦H/e≦3.0 、 1.0≦L/H≦50.0 、 1.0≦(p-w)/w≦100.0 の関係を満たすことを特徴とする。
