公开号为CN105415986A的发明专利中提供了一种不同层外绕线强度有区别的缆型胎圈，减轻重量，节约成本。
然而，现有技术的缆型胎圈的外缠线钢丝为圆形断面，这种结构下线与线之间的排列间隙较大，胎圈的有效强度不高，并且，外缠线钢丝与芯圈钢丝形成线接触，当外缠线钢丝为至少两层时，相邻两层外缠线钢丝之间易形成点接触，在应力作用下形成应力集中，降低胎圈的使用寿命。
发明内容

为解决现有技术问题，本发明公开了一种缆型胎圈，包括位于胎圈中间位置的芯圈钢丝和至少一层缠绕在芯圈钢丝外的外缠线钢丝，每层的外缠线钢丝均沿芯圈钢丝的周向均匀缠绕；外缠线钢丝的断面为具有长轴和短轴的扁平形面，长轴与胎圈断面的径向垂直，短轴与胎圈断面的径向平行；外缠线钢丝和芯圈钢丝之间为面接触；外缠线钢丝至少为两层时，外缠线钢丝层之间形成线接触。
作为优选方案，长轴和短轴的比值Rax为1＜Rax≤2。
作为优选方案，长轴和短轴的比值Rax为1.1≤Rax≤1.8。
作为优选方案，长轴为0.80～3.00mm。
作为优选方案，长轴为1.50～2.50mm。
作为优选方案，外缠线钢丝至少为两层时，每层外缠线钢丝的缠绕方向均为相同。
作为优选方案，外缠线钢丝至少为两层时，相邻两层外缠线钢丝之间的缠绕方向互为反向。
作为优选方案，外缠线钢丝至少为两层时，每层外缠线钢丝的尺寸均相同。

具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
本发明中，“扁平形面”是指包括两个平行的直边和两个分别连接两个直边两端且成对称的弧边的面。在垂直于直边的方向上，两个直边之间的距离为该扁平形面的短轴尺寸，该尺寸对应的线段为扁平形面的短轴；在平行于直边的方向上，两个弧边之间的最大距离为该扁平形面的长轴尺寸，该尺寸对应的线段为扁平形面的长轴。基于断面的形状可以确定外缠线钢丝为具有两个平行且沿直线延伸的壁和两个对称且具有弧度的壁的扁平形钢丝。该种外缠线钢丝可以采用一个或多个配合成型的模具对圆钢丝拉拔获得，也可以采用一组或多组两辊轧机对圆钢丝轧制获得。
“S向”与“Z向”是指互为相反的两个缠绕方向。
胎圈断面直径为胎圈截面的外接圆直径。
胎圈总断裂力为芯圈钢丝与外缠钢丝的断裂力之和。
胎圈有效断面强度为胎圈总断裂力与胎圈截面外接圆面积的比值。
根据胎圈总断裂力与断面尺寸的设计要求，胎圈的外缠线钢丝一般为1～6层，也可以设置更多层。
胎圈在实际使用时，最外层钢丝的受力最大，内层钢丝的受力相对较小，因此当选择外缠线钢丝的规格不同时，选择外层钢丝的强度较高，内层钢丝的强度相对较低，能获得更有利的设计结构。
疲劳断裂保持力测量在胎圈运行预定时间后进行。将包括缆型胎圈的轮胎安装并运行预定时间，接着从轮胎取出胎圈，测量钢丝的断裂力，与其初始断裂力的比值为疲劳断裂保持力。疲劳断裂保持力越接近1，说明断裂力的损失越小，具有更好的使用寿命。
