Title (EN) AIRCRAFT TIRE
(FR) PNEU D'AERONEF
(JA) 航空機用タイヤ
Abstract:
(EN) Provided is an aircraft tire having a carcass structure that, without increasing the weight of the tire, fully meets the high pressure-tolerance requirements of recent years. The aircraft tire (9) has a carcass (4) made by layering at least two toroidal carcass layers (3) that straddle a pair of bead parts (2, 2) and comprise rubber-covered cord. Between each pair of adjacent carcass layers (3) in the carcass (4), the carcass layer (3) further towards the outside in the width direction has an even lower elongation at rupture than the carcass layer (3) further towards the inside in the width direction.
(FR) L'invention concerne un pneu d'aéronef dont la structure de la carcasse, sans augmentation du poids du pneu, satisfait pleinement aux exigences élevées de tolérance de pression des dernières années. Le pneu d'aéronef (9) présente une carcasse (4) obtenue par stratification d'au moins deux couches de carcasse toroïdales (3) qui chevauchent une paire de parties de talon (2, 2) et sont constituées de câbles caoutchoutés. Entre chaque paire de couches de carcasse contiguës (3) dans la carcasse (4), la couche de carcasse (3) au delà vers l'extérieur dans le sens de la largeur présente un allongement à la rupture encore plus bas que la couche de carcasse (3) au delà vers l'intérieur dans le sens de la largeur.
(JA)  タイヤの重量を増加させずに、近年の高い耐圧性の要求を十分に満足するカーカス構造を有する航空機用タイヤを提供する。航空機用タイヤ9は、一対のビード部2、2間に跨ってトロイダル状に延び、ゴム被覆したコードからなる2層以上のカーカス層3を積層してなるカーカス4を有する。また、カーカス4の隣接するカーカス層3間における、幅方向外側のカーカス層3の破断時伸びが、幅方向内側のカーカス層3の破断時伸びよりも小さい。
