3×0.22/9×0.20HT钢丝帘线在全钢载重子午线轮胎胎体中的应用

Application of 3×0.22/9×0.20HT steel cord in carcass of TBR tire

介绍3×0.22/9×0.20HT钢丝帘线及其性能指标,研究其在295/80R22.5 16PR全钢载重子午线轮胎胎体中的应用。结果表明,以3×0.22/9×0.20HT钢丝帘线替代3+9+15×0.175+0.15钢丝帘线用于全钢载重子午线轮胎胎体中,可提高轮胎的耐久性能和速度性能,减小轮胎质量,降低生产成本。

The performance characteristics of 3 × 0.22/9 ×0.20HT steel cord were described,and its application in carcass of 295/80R22.5 16PR TBR tire was investigated. The results showed that,by using 3 ×0.22/9 × 0.20HT steel cord instead of 3＋9＋15 ×0. 17＋0. 15 steel cord in the carcass of TBR tire, the endurance performance and speed performance of finished tire were improved, and the tire weight and production cost were reduced.
