| 中文摘要: |
| 介绍3+9+15×0.20ST钢丝帘线在12.00R20高负荷全钢载重子午线轮胎胎体中的应用。与3+9+15×0.225HT钢丝帘线相比，3+9+15×0.20ST钢丝帘线直径和线密度小，在破断力/直径与破断力/线密度方面有优势，以其替代3+9+15×0.225HT钢丝帘线用于12.00R20高负荷全钢载重子午线轮胎胎体，成品轮胎的外缘尺寸基本不变，强度性能、耐久性能、胎圈耐久性能和高速性能均有所提高，安全性能略有提高，胎体成本大幅下降，同时有效解决了苛刻使用条件下轮胎胎肩脱层和胎圈空等问题。 |
| 英文摘要: |
| The application of 3+9+15×0.20ST steel cord in the carcass of high load truck and bus radial tire was introduced.Compared with 3+9+15×0.225HT steel cord， 3+9+15×0.20ST steel cord possessed smaller diameter and cord density，and showed the advantages at rupture strength/diameter ratio and rupture strength/cord density ratio.Using 3+9+15×0.20ST steel cord instead of 3+9+15×0.225HT steel cord in the carcass of 12.00R20 high load truck and bus radial tire，it was confirmed by the test of the finished tires that，the inflated peripheral dimension changed little，the strength performance，endurance，bead endurance and high speed performance were improved，the safety performance was improved slightly，the cost of carcass was reduced remarkably，and at the same time the problems of shoulder separation and bead separation under severe using conditions were effectively solved. |
