The invention relates to the technical field of tire manufacturing, in particular to an all-steel radial tire bead which structurally comprises a lining layer, reinforcing nylon, a cord layer, a 1 # reinforcing steel wire, a lower apex rubber core, an upper apex rubber core located above the lower apex rubber core, a steel wire ring located below the lower apex rubber core, a cord layer, a 2 # reinforcing steel wire, sidewall rubber and seam allowance wear-resistant rubber. Sidewall rubber; and 2 # reinforcing steel wires are added among the outer side end points of the reinforcing steel wires, the outer side end points of the cord thread layers and the nylon reinforcement. The heavy-load tire bead structure of the all-steel radial tire is higher in tire bead rigidity and more reasonable in material gradient distribution, the durability of the tire bead of the tire is improved, the service life of the tire under the high heavy load condition is prolonged, and the problems that the anti-wrapping end point of a cord layer of the tire bead part is cracked or disengaged, and the seam allowance part is exploded due to the cracking or disengagement are solved.

    本申请涉及轮胎制造技术领域,具体涉及一种全钢子午线轮胎胎圈,所述胎圈结构为:内衬层、补强尼龙,帘线层,1#补强钢丝,下三角胶芯,位于下三角胶芯上方的上三角胶芯,位于下三角胶芯下方的钢丝圈,帘线层,2#补强钢丝,胎侧型胶,子口耐磨胶,胎侧胶;在补强钢丝外侧端点与帘线层外侧端点与尼龙补间加入2#补强钢丝。本申请提供了一种胎圈刚度更高,材料梯度分布更合理的全钢子午线轮胎重载胎圈结构,提高轮胎的胎圈耐久性能及高重载条件下的使用寿命,解决了胎圈部位帘线层反包端点处开裂或脱空,以及上述问题导致的子口部位爆破的问题。
