The invention relates to the technical field of tire production, and particularly discloses an all-steel radial tire bead structure which comprises a tire body layer, a tire bead, a steel wire reinforcing layer, a lining layer and a tire side layer, the steel wire reinforcing layer and the lining layer are arranged between the tire body layer and the tire side wall layer in parallel, and the covered edge of the steel wire reinforcing layer is opposite to one end of the lining layer, so that the covered edge of the steel wire reinforcing layer and the lining layer are positioned on the same plane; the tire body layer, the tire side layer, the steel wire reinforcing layer and the lining layer form a composite layer structure, and the tire bead is wrapped with the composite layer structure; the lining layer and the steel wire wrapping cloth with double wrapping edges are positioned in a tiled design, so that the transition of a tire bead part is improved, and a transition point is eliminated; after the material of the ring part is changed into a tiled design, no obvious transition point exists from the center of the material to the side edge of the tire, so that the tire body pressing speed can be increased, and the single tire efficiency is improved; the appearance design defects such as seam allowance bubbles and lining bubbles are effectively overcome from the root of design, and the durability of the product is improved.

    本发明涉及轮胎生产技术领域,具体公开了一种全钢子午线轮胎胎圈结构,包括:胎体层、胎圈、钢丝补强层、内衬层和胎侧层;所述钢丝补强层和所述内衬层并列设置于所述胎体层和所述胎侧层之间,且所述钢丝补强层的包边与所述内衬层的一端相对,使所述钢丝补强层的包边与所述内衬层处于同一平面;所述胎体层和所述胎侧层与所述钢丝补强层和内衬层构成复合层结构,包裹于所述胎圈的外部;内衬层与双包边的钢丝包布定位为平铺式设计,使胎圈部位过渡改善,消除过渡点;圈部材料改用平铺式设计后,物料中心至胎侧边部无明显过渡点,可加快胎体压合速度,提升单胎效率;从设计根源有效解决子口气泡、内衬气泡等外观设计缺陷,提升产品耐久性能。
