| 中文摘要: |
| 以新型4＋3×0.35SUT钢丝帘线替代3＋8×0.33ST钢丝帘线应用于全钢载重子午线轮胎带束层。试验结果表明：与3＋8×0.33ST钢丝帘线相比，4＋3×0.35SUT钢丝帘线结构更简单，直径减小，破断力和刚度降低，渗胶性能好；在带束层中以4＋3×0.35SUT钢丝帘线替代3＋8×0.33ST钢丝帘线后，成品轮胎的外缘尺寸、强度性能和耐久性能均满足设计和相关标准要求，且轮胎质量减小。 |
| 英文摘要: |
| The new 4＋3×0.35SUT steel cord was applied in the belt layer of truck and bus radial tire and compared to 3＋8×0.33ST steel cord.The test results showed that，compared with 3＋8×0.33ST steel cord，4＋3×0.35SUT steel cord possessed simpler structure，smaller diameter，lower breaking strength and stiffness，and better rubber penetration property.With 4＋3×0.35SUT steel cord in the belt layer，the inflated peripheral dimension，strength and endurance performance of finished tire met the requirements of the design and corresponding standards，and the tire cost was lower than that with 3＋8×0.33ST steel cord. |
