The invention discloses an urban rail transit tire bead structure. The urban rail transit tire bead structure comprises a composite bead filler core, a steel wire ring, a carcass ply, a steel wire fabric reinforcing layer, seam allowance nylon wrapping cloth and seam allowance protective rubber. The carcass ply wraps the steel wire ring, the carcass ply is bound by the steel wire fabric reinforcing layer through a U-shaped design, the inner side end point of the steel wire fabric reinforcing layer is arranged between the carcass ply and a lining layer, and the outer side end point of the steelwire fabric reinforcing layer is arranged between the carcass ply and the seam allowance nylon wrapping cloth. The upper end point of the seam allowance nylon wrapping cloth is located above a reverse wrapping end point of the carcass ply, and the lower end point of the seam allowance nylon wrapping cloth is ended at the steel wire ring. The thickness of the bead rubber can be reduced by optimizing the rubber core structure and adjusting the difference grade of the tire body and steel wire wrapped cloth, and heating and manufacturing cost can be controlled.

    本发明公开了一种城市轨道交通轮胎圈部结构,包括复合三角胶芯、钢丝圈、胎体帘布层、钢丝帘布加强层、子口尼龙包布和子口护胶;所述胎体帘布层包裹钢丝圈,钢丝帘布加强层通过“U型”设计设计将胎体帘布层进行束缚,钢丝帘布加强层内侧端点设置在胎体帘布层和内衬层之间,外侧端点设置在胎体帘布层和子口尼龙包布之间,所述子口尼龙包布上端点位于胎体帘布层反包端点的上方,其下端点终止于钢丝圈,本发明胎圈填充料厚度适中,可降低部件生产、存储过程以及生胎制造过程中的品控成本,本发明通过优化胶芯结构、调整胎体和钢丝包布差级,可降低圈部橡胶厚度,有利于控制生热和制造成本。
