The invention relates to the technical field of tires, and discloses a meridian aircraft tire which comprises a tire body lining, a tire body layer, a belted layer and a tire surface layer, the curvature radius of a belted layer is limited, so that the curvature radius of the belted layer is larger than the inner surface of a tire lining and is sequentially larger than the outer surface of a tread layer, and the curvature radius change rate of the belted layer compared with the inner surface of the tire lining is limited; and the change rate of the curvature radius of the outer surface of the belted layer compared with the tread layer is also limited, so that the belted layer can tightly hoop the tire body layer after being inflated, and further, the larger tensile circumferential stress is borne, the wear resistance of the tire shoulder part is improved, and the eccentric wear phenomenon is solved.
本发明涉及轮胎技术领域,公开了一种子午线航空轮胎,包括:胎体内衬、胎体层、带束层和胎面层;其通过对带束层的曲率半径进行限定,使带束层的曲率半径大于胎体内衬的内表面,顺次大于胎面层的外表面,并且对带束层相比较胎体内衬的内表面的曲率半径变化率予以限定,对带束层相比较胎面层的外表面的曲率半径变化率也予以限定,以使得在充气后,带束层能够紧箍胎体层,进而承载较大的拉伸周向应力,提高胎肩部的耐磨性能,解决偏磨现象。
