The invention relates to the technical field of meridian aircraft tires, in particular to a meridian aircraft tire bead structure aiming at large sinkage, which comprises a circular-section steel ring, triangular-section filling rubber, a tire body cord fabric layer and a tire body material layer, and the triangular-section filling rubber is further divided into an inner-layer filling rubber part and an outer-layer filling rubber part which are connected with each other. A boundary section between the inner-layer filling adhesive part of the triangular-section filling adhesive and the outer-layer filling adhesive part of the triangular-section filling adhesive in the section is a line segment L, and the line segment L is tangent to the outermost peripheral point, located in the horizontal direction, of the circular section of the circular-section steel ring. According to the invention, the problem that the tire bead position of the large-sinkage meridian aircraft tire is easy to delaminate and swell can be solved, the use requirements of the meridian aircraft tire can be met, the tire bead structure is optimized, the performance and reliability of the aircraft tire are improved, the maintenance cost and use risk of the tire are reduced, and a powerful guarantee is provided for aviation safety.

    本发明涉及子午线航空轮胎技术领域,具体地说是一种针对大下沉量的子午线航空轮胎胎圈结构,包括圆截面钢圈、三角形截面填充胶、胎体帘布层、胎体材料层,其中三角形截面填充胶还分成相接的内层填充胶部分及外层填充胶部分,三角形截面填充胶的内层填充胶部分与该三角形截面填充胶的外层填充胶部分之间在截面中的分界线段为线段L,线段L与圆截面钢圈的圆截面的位于水平方向的最外周点处相切。本发明能够解决大下沉量的子午线航空轮胎的胎圈位置易出现脱层鼓包等的问题,可以满足子午线航空轮胎的使用要求,优化胎圈结构,提高航空轮胎的性能和可靠性,降低轮胎的维护成本和使用风险,为航空安全提供有力保障。
