轮胎胎圈不仅应尺寸稳定并要能承受一定的负荷。轮胎是动态的安全产品 ,特别是在汽车载荷很大或高速转向时 ,轮胎胎圈和胎圈单边受力(径向力和侧向力 )非常大。如果组成胎圈的骨架材料———单根钢丝与橡胶粘合性不好 ,则易造成胎圈钢丝松散 ,从而导致轮胎爆破。因此 ,胎圈钢丝
The tire bead should not only be dimensionally stable but also be able to withstand a certain load. Tires are dynamic safety products, with unidirectional stress (radial and lateral forces) on the tire beads and beads especially when the car is heavily loaded or steered at high speeds. If the composition of the bead skeleton material - a single wire and rubber adhesion is not good, it will easily lead to loose bead wire, resulting in tire blasting. Therefore, the bead wire
