3+9+15×0.225HT钢丝帘线在全钢载重子午线轮胎胎体和带束层中的应用

Application of 3+9+15×0.225HT Steel Cord in Carcass and Belt of Truck and Bus Radial Tire

以3+9+15×0.225HT钢丝帘线替代3+9+15×0.22+1NT钢丝帘线用于12.00R20 18PR全钢载重子午线轮胎胎体和带束层。结果表明,以3+9+15×0.225HT钢丝帘线替代3+9+15×0.22+1NT钢丝帘线用于12.00R20 18PR全钢载重子午线轮胎胎体和带束层,成品轮胎的外缘尺寸基本不变,轮胎强度性能、耐久性能和速度性能以及胎圈耐久性能均有较大提高,在不增加胎体和带束层质量和成本的情况下,胎体和带束层安全倍数大幅提高,从而提高了轮胎的使用安全性能和负荷能力。

In this paper,the 3-F 9＋ 15 × 0. 225HT steel cord was applied to replace 3＋9＋ 15 × 0.22＋1NT steel cord in the carcass and belt of 12.00R20 18PR truck and bus radial tire. The results showed that, the inflated peripheral dimension of the finished tire changed little, and the strength performance, endurance performance, speed performance and bead endurance were improved significantly. Without increasing the weight and cost of the carcass and belt, the safety factor of the carcass and belt increased significantly, so that the safety and loading capacity of the tire were improved.
