    Abstract:  最内層ベルトのスチールコード使用量を減らした場合でも、コードの坐屈やベルトの折れの発生をなくすことができ、タイヤの軽量化を図るとともに耐久性を向上させることのできる空気入りタイヤを提供する。  少なくとも1層のベルト3を備え、ベルト3のうち最内層ベルト3aがタイヤ周方向に対し45°~90°の角度を有する空気入りタイヤ10である。最内層ベルト3aに撚りピッチが9mm以上15mm以下の単撚りオープンコードが適用されてなる。単撚りオープンコードは、破断伸びが3.8%以下であり、かつ、単撚りオープンコードを構成するフィラメントの線径が0.25mm~0.38mmであることが好ましい。

    Abstract translation: 提供一种充气轮胎,即使在最内层带中使用的钢丝绳的数量减少,也能够消除绳索的翘曲和带的折痕的发生,从而减轻重量并改善 轮胎的耐久性。 充气轮胎(10)包括至少一层的带(3),其最内层带(3a)相对于轮胎周向具有45度至90度的角度。 9mm至15mm的扭转间距的单扭开口帘线被施加到最内层带(3a)。 优选的是,单捻开口帘线的断裂伸长率为3.8%以下,构成单捻开口帘线的长丝的直径为0.25mm〜0.38mm。

    Abstract: To provide a pneumatic tire wherein the lightweight properties of a tire is secured while improving the plunger energy and BES resistance thereof, which is particularly suitable for tires for a large passenger car or extra load tires.A pneumatic tire comprising a carcass 1 as a skeleton, and at least two belt layers 2a, 2b each formed by rubberizing a plurality of steel cords arranged obliquely with respect to the tire circumferential direction on the outside in the tire radial direction of the crown portion of the carcass is provided. The steel cord is composed of two or more core wires and five to seven sheath wires twisted together around the core wires; the interval between adjacent steel cords in the belt layer is more than 1.0 mm and not more than 1.50 mm; and the gauge of the belt layer is not less than 1.20 mm and not more than 1.60 mm.

    Abstract translation: 提供一种充气轮胎,其中轮胎的轻质性得到保证,同时提高了柱塞能量和BES阻力,特别适用于大客车或额外载重轮胎的轮胎。 一种包括胎体1作为骨架的充气轮胎,以及至少两个带状层2a,2b,其通过在冠部的轮胎径向上在外侧上相对于轮胎周向倾斜地布置的多个钢丝帘线形成, 的胎体。 钢丝帘线由两根或多根芯线组成,五根至七根护套线缠绕在芯线周围; 带束层中相邻的钢丝绳之间的间隔大于1.0mm且不大于1.50mm; 带束层的厚度不小于1.20mm且不大于1.60mm。

    Abstract: A composite hybrid cord comprising a core comprising of a first bundle of synthetic filaments having a filament tenacity of from 10 to 40 grams per decitex and a plurality of cabled strands helically wound around the core, each cabled strand comprising of a plurality of metal strands helically wound around a center second bundle of synthetic filaments that have a filament tenacity of from 10 to 40 grams per decitex. The ratio of the largest cross sectional dimension of the first bundle of synthetic filaments to the largest cross sectional dimension of the second bundle of synthetic filaments is from 1.5:1 to 20:1. The metallic filaments of the cabled strands have an elongation at break that is no more than 24 percent different from the elongation at break of the synthetic filaments of the first and second bundles.
