| 中文摘要: |
| 研究2＋7×0.30ST钢丝帘线在全钢载重子午线轮胎带束层中的应用。结果表明：与3＋8×0.33HT钢丝帘线相比，2＋7×0.30ST钢丝帘线的直径和线密度小，渗胶性能好；以其替代3＋8×0.33HT钢丝帘线用于12R22.5 16PR全钢载重子午线轮胎带束层中，可以提高轮胎的强度性能、耐久性能、高速性能和接地印痕性能，同时减小轮胎质量，降低生产成本。 |
| 英文摘要: |
| The application of 2＋7×0.30ST steel cord in the belt of truck and bus radial tire was investigated.The results showed that，compared with 3＋8×0.33HT steel cord，2＋7×0.30ST steel cord possessed smaller diameter and linear density，and better rubber permeability.Using 2＋7×0.30ST steel cord instead of 3＋8×0.33HT steel cord in the belt of 12R22.5 16PR truck and bus radial tire，the strength，endurance，high-speed performance and footprint performance of the tire was improved，and the weight and product cost of tire were reduced. |
