The invention discloses a meridian aircraft tire with a high-rigidity tire crown, and relates to the technical field of tires, the tire comprises a tire body layer and is also provided with a belt reinforcing structure, the whole tire is symmetrical relative to an equatorial plane EP, the tire body layer comprises at least one inner cord fabric layer 1a, and the inner cord fabric layer 1b comprises at least one outer cord fabric layer 1b. At least two inner plies may be wrapped on the annular bead member from an axial inner side of the annular bead member toward an axial outer side thereof and extend radially outward toward the crown to form respective turn-up ply portions; the crown of the finished aircraft tire has high rigidity, the inflation outer edge size is stable, and the method has the remarkable advantages of structural size design and model selection, mold size determination, elimination of framework material internal stress change caused by inflation secondary expansion of the finished aircraft tire and retreading frequency increase.
本发明公开了一种高刚性胎冠的子午线航空轮胎,涉及轮胎技术领域,该轮胎包括胎体层并且还具有带束加强结构,整个轮胎相对赤道平面EP对称,胎体层包括至少一个内帘布层1a,至少两层内帘布层可从环形胎圈构件的轴向内侧朝向其轴向外侧缠绕在环形胎圈构件上,并且朝着胎冠径向向外延伸以形成相应的反包帘布部分;本申请中成品航空轮胎冠部具有较高的刚度,充气外缘尺寸稳定,对结构尺寸设计选型、模具尺寸确定、消除成品航空轮胎充气二次膨胀带来的骨架材料内应力变化、翻新次数增加具有显著优势。
