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. |
