| 中文摘要: |
| 介绍无内胎全钢载重子午线轮胎胎体用超高强度0.22＋18×0.20ST钢丝帘线的结构和性能特征，并与0.25＋12×0.225HT钢丝帘线进行对比。结果表明，与0.25＋6＋12×0.225HT钢丝帘线相比，0.22＋18×0.20ST钢丝帘线的疲劳强度和疲劳后破断力高，等强度替代后可减小钢丝帘线和胶料用量，实现轮胎轻量化。 |
| 英文摘要: |
| The structure and performance characteristics of ultra-high strength 0.22＋18×0.20ST steel cord for carcass of tubeless truck and bus radial tire were introduced,and compared with 0.25＋6＋12×0.225HT steel cord.The results showed that,compared with 0.25＋6＋12×0.225HT steel cord,the fatigue strength and breaking force of 0.22＋18×0.20ST steel cord after fatigue were higher,which indicated that less amount of steel cord was required to achieve the same level of strength.In another word,the tire weight could be reduced with 0.22＋18×0.20ST steel cord. |
