3×0.24+9×0.225CCST钢丝帘线在全钢载重子午线轮胎胎体中的应用

Application of 3×0.24+9×0.225CCST Steel Cord in Carcass of Truck and Bus Radial Tire

对比研究3×0.24+9×0.225CCST和3+9+15×0.175+0.15钢丝帘线在全钢载重子午线轮胎胎体中的应用。结果表明,3×0.24+9×0.225CCST钢丝帘线的直径较小,破断力较高,其代替3+9+15×0.175+0.15钢丝帘线应用于全钢载重子午线轮胎胎体中,可提高轮胎的强度性能和耐久性能,同时减小轮胎质量和降低生产成本。

The application of 3×0. 24＋9×0. 225 CCST steel cord in the carcass of truck and bus radial tire was investigated,and compared with 3 ＋ 9 ＋ 15×0. 175 ＋ 0. 15 steel cord. The results showed that,the diameter of 3×0. 24 ＋ 9×0. 225 CCST steel cord was smaller than that of 3 ＋ 9 ＋ 15×0. 175 ＋ 0. 15 steel cord and the breaking force was higher. By using 3×0. 24 ＋ 9×0. 225 CCST steel cord to replace 3 ＋ 9 ＋15×0. 175＋0. 15 steel cord in the carcass,the strength and durability of the tire were improved,and the tire weight and production cost were reduced.
