The invention relates to the technical field of tires, in particular to a tubeless tire which is characterized in that the shore hardness of apex soft rubber and hard rubber, the height difference between the inner height of a toe reinforcing layer and the height of an assembly line, the height difference between a nylon reinforcing layer and the inner end point of the toe reinforcing layer and the height distance between the outer end point of the toe reinforcing layer, the outer end point of cord fabric and the outer end point of nylon are controlled; double-layer wrapping cloth is arranged, and a layer of toe opening outer end point isolation rubber is arranged between the outer end point of the toe opening reinforcing layer and the end point of the curtain cloth; therefore, the shearing force between the steel wire material and the rubber material in the tire bead and the stress concentration between framework end points are reduced, the stress stability of the tire bead is improved, the service life of the tire is prolonged, and the safety of the tire is improved.
本发明涉及轮胎技术领域,具体涉及一种无内胎轮胎,通过控制三角胶软胶、硬胶邵氏硬度,趾口加强层内高度与装配线高度差,尼龙加强层与趾口加强层内端点高度差,趾口加强层外端点、帘布外端点、尼龙外端点高度间距;并且设置双层包布,在趾口加强层外端点与帘布端点之间设置一层趾口外端点隔离胶;以此降低胎圈内部材料钢丝材料和橡胶材料之间剪切力和骨架端点之间的应力集中,提升轮胎胎圈受力稳定性,提升轮胎使用寿命和安全性。
