The invention relates to the technical field of tire production, and particularly discloses an all-steel truck radial tire belted layer structure and a tire, the belted layer structure comprises a first belted layer, a second belted layer, a third belted layer, a fourth belted layer and a cap ply; the belted layer I, the belted layer II, the belted layer III and the belted layer IV are stacked in sequence; the cap ply is arranged between the belt ply II and the belt ply III and is wound and laid by a cap ply strip along the circumferential direction of the tire, and the laying track is Z-shaped. A belted layer structure with four belted layers and a cap ply is adopted, and a cap strip between the second belted layer and the third belted layer is wound in the circumferential direction of the tire and laid in a Z shape. After the cap strip is formed, inflated, expanded and vulcanized, the cap strip is completely straightened or slightly bent, the problem that the expansion coefficients of the belted layer and the cap strip are not matched is solved, the Z-shaped cap strip winding layer forms a hoop effect on the belted layer and a tire body, radial expansion of the tire after inflation is restrained, interlayer stress of the belted layer is reduced, and the tire performance is improved. The safety and the service life of the tire are improved.
本发明涉及轮胎生产技术领域,具体公开了一种全钢载重子午线轮胎带束层结构及轮胎,带束层结构包括:带束层一、带束层二、带束层三、带束层四和冠带层;带束层一、带束层二、带束层三和带束层四依次叠放;冠带层设置于带束层二和带束层三之间,由冠带条沿轮胎的周向缠绕铺设,铺设轨迹呈Z字形。采用四层带束层外加冠带层的带束层结构,在带束层二和带束层三之间的冠带条沿轮胎周向缠绕,呈Z字形铺设;冠带条经过成型充气膨胀、硫化后,冠带条完全伸直或者轻微弯曲,解决带束层与冠带条膨胀系数不匹配的问题,Z字形冠带条缠绕层对带束层及胎体形成环箍效应,抑制轮胎充气后径向膨胀,降低带束层的层间应力,提升轮胎的安全性及使用寿命。
