The invention relates to the technical field of tires, and discloses a meridian aircraft tire which has a first state of unvulcanized expansion and unpressurized expansion, a second state of only vulcanized expansion and uninflated expansion, and a third state of vulcanized expansion and inflated expansion. The meridian aircraft tire comprises a tire body, and the tire body comprises a lining layer arranged on the inner side of the tire body, a tread arranged on the periphery of the tire body and a belted layer located between the lining layer and the tread. Wherein when the tire body is in the first state, the distance between the lining layer located on the equatorial plane of the tire body and the tread is recorded as Hg, when the tire body is in the second state, the distance between the lining layer located on the equatorial plane of the tire body and the tread is recorded as Hg ', and Hg' is smaller than Hg, and (Hg-Hg ')/Hg is larger than 0 and smaller than or equal to 12%. According to the meridian aircraft tire provided by the invention, the wear resistance and durability can be improved, so that the performance is improved, and the meridian aircraft tire has relatively high yield.
本发明涉及轮胎技术领域,公开了一种子午线航空轮胎,具有未硫化膨胀以及未充压膨胀的第一状态、仅经过硫化膨胀未充气膨胀的第二状态、经过硫化膨胀和充气膨胀第三状态;子午线航空轮胎包括轮胎本体,轮胎本体包括设置在轮胎本体内侧的内衬层、设置在轮胎本体外周的胎面以及位于内衬层和胎面之间的带束层;其中,当轮胎本体处于第一状态时,位于轮胎本体赤道平面上的内衬层和胎面之间的距离记为Hg,当轮胎本体处于第二状态时,位于轮胎本体赤道平面上的内衬层和胎面之间的距离记为Hg′,满足:Hg'<Hg,且0<(Hg‑Hg′)/Hg≤12%。本发明通过提供一种子午线航空轮胎,能够提高耐磨性、耐久性,从而提高性能,并且具有较高的成品率。
