The invention discloses a truck radial tire with a full-contact steel wire ring. The truck radial tire comprises a tread, a belted layer, tire shoulder pad rubber, a sidewall, upper apex, nylon wrapping cloth, a tire body, steel wire wrapping cloth, lower apex, seam allowance wear-resistant rubber, a lining layer and the steel wire ring. The invention further provides a winding disc of the truck radial tire with the full-contact type steel wire ring. According to the steel wire ring composed of the regular hexagonal tire bead steel wires, the left face and the right face of each regular hexagonal tire bead steel wire are automatically vertical faces through the triangular sawtooth faces of the corresponding winding discs of the steel wire ring, and therefore it is guaranteed that the six faces of the regular hexagonal tire bead steel wires are attached to one another to form a face contact stable structure with a self-locking function; no gap exists between the steel wires, it is guaranteed that no residual air exists in the wound steel wire ring, the early-stage damage problems such as ring empty, three-wire cracks, seam allowance burning and wire drawing explosion caused by too high heat generation of the tire bead under the heavy load condition of a vehicle are avoided, and powerful guarantee is provided for long-term durability and safe driving of the tire.
本发明公开了一种具有全接触式钢丝圈的载重子午线轮胎,包括胎面、带束层、胎肩垫胶、胎侧、上三角胶、尼龙包布、胎体、钢丝包布、下三角胶、子口耐磨胶、内衬层、钢丝圈。本发明还提供了一种具有全接触式钢丝圈的载重子午线轮胎的缠绕盘。采用正六边形胎圈钢丝组成的钢丝圈,通过对应的钢丝圈的缠绕盘的三角形锯齿面使各个正六边形胎圈钢丝左右的两个面自动的为垂直面,从而保证正六角形胎圈钢丝的六个面是相互贴合成具有自锁功能的面接触稳定结构,各个钢丝之间没有空隙,保证缠绕后的钢丝圈里面没有残留空气,避免车辆在重载条件下因胎圈生热过高引起的圈空、三线裂、烧子口和抽丝爆等早期损坏问题,为轮胎长期耐久和安全行驶提供有力保障。
