3×0.22/9×0.20CCHT钢丝帘线在全钢轻型载重子午线轮胎胎体中的应用

Application of 3×0. 22/9×0. 20CCHT Steel Cord in Carcass of All-steel Light Truck and Bus Radial Tire

研究3×0.22/9×0.20CCHT钢丝帘线在全钢轻型载重子午线轮胎胎体中的应用。结果表明,采用3×0.22/9×0.20CCHT钢丝帘线替代3+9×0.22+0.15HT钢丝帘线应用于全钢轻型载重子午线轮胎胎体,加工工艺性能良好,成品轮胎外缘尺寸和强度性能满足国家标准要求,耐久性能提高,同时可降低生产成本。

The application of 3×0. 22/9×0. 20 CCHT steel cord in the carcass of all-steel light truck and bus radial tire was investigated. The results showed that,by using 3×0. 22/9×0. 20 CCHT steel cord instead of 3 ＋ 9×0. 22 ＋ 0. 15 HT steel cord in the carcass of all-steel light truck and bus radial tire,the processing property was good,the peripheral dimension and strength of the finished tire met the requirements of national standard,the endurance performance was improved,and the production cost was reduced.
