| 中文摘要: |
| 研究2＋7×0.35UT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＋8×0.33ST钢丝帘线相比，2＋7×0.35UT钢丝帘线的渗胶性能更好，工艺性能稳定；以2＋7×0.35UT钢丝帘线代替3＋8×0.33ST钢丝帘线用于12.00R20全钢载重子午线轮胎带束层中，轮胎的充气外缘尺寸和强度性能符合国家标准要求，耐久性能提高，滚动阻力系数降低。 |
| 英文摘要: |
| The application of 2＋7×0.35UT steel cord in belt of all-steel truck and bus radial tire was
studied.The results showed that，compared with 3＋8×0.3ST steel cord，2＋7×0.35UT steel cord exhibited better compound permeability and stable processability.using 2＋7×0.35UT steel cord to replace 3＋8×
0.33ST steel cord in the belt of 12.00R20 all-steel truck and bus radial tire，the inflated peripheral dimensions and strength performance of tires met the requirements of national standards，the durability was improved, the rolling resistance coefficient was decreased. |
