The invention discloses an all-steel radial tire capable of improving the tire body cord thread elongation rate, relates to the field of radial tires, and is simple in structure, compared with the prior art, by limiting the extension rate range of the tire body cord thread, the tire body molding plane width is correspondingly adjusted, and the length of the tire body cord thread of a blank inner tire is increased, the twitching amount and time of tire body cords are reduced, on the premise that the defects of cord bending, uneven tire interior and the like of a finished tire are avoided, the side part of the tire blank is quickly and tightly matched with the side plate of the mold in the vulcanization shaping process, extrusion on the vulcanized rubber bag is formed through the shaping pressure effect of the rubber bag on the blank, and the concentrated space of bubbles is eliminated; bubbles on the side part of the embryo are uniformly dispersed, the defective rate of broken holes in the tire side in the tire manufacturing process is reduced, and the product performance and the service life are improved.
本发明公开了一种改善胎体帘线伸张率的全钢子午线轮胎,涉及子午线轮胎领域,本发明结构简单,通过对胎体帘线伸张率范围的限定,使本发明相较于现有技术,对应调整了胎体成型的平面宽,增加了胚胎内胎体帘线长度,减少胎体帘线的抽动量和时间,在避免出现成品胎出现帘线弯曲、胎里不平等缺陷的前提下,使胎胚侧部在硫化定型过程中与模具侧板快速的紧密吻合,通过胶囊对胚胎的定型压力作用形成对硫化胶囊的挤压,消除气泡的集中空间,使胚胎侧部气泡均匀分散,降低了轮胎制造过程中的胎侧烂洞废次品率,同时提升了产品性能和寿命。
