中文摘要: |
研究以2+7×0.30ST钢丝帘线替代3×0.20+6×0.35HT钢丝帘线在7.50R16 14PR轻型载重子午线轮胎带束层中的应用。结果表明:与3×0.20+6×0.35HT钢丝帘线相比,2+7×0.30ST钢丝帘线整体呈椭圆形排布,帘线直径相同,强度更高;将2+7×0.30ST钢丝帘线应用于带束层中,成品轮胎的外缘尺寸符合国家标准要求,耐久性能相当,强度性能和高速性能略有提升,滚动阻力降低,单胎质量减小。 |
英文摘要: |
The application of 2+7×0.30ST steel cord instead of 3×0.20+6×0.35HT steel cord in belts of light truck and bus radial tire was studied.The results showed that,compared to 3×0.20+6×0.35HT steel
cord,2+7×0.30ST steel cord was arranged in an elliptical shape,with the same diameter and higher strength.
Using 2+7×0.30ST steel cord in belts,the inflated peripheral dimension of the finished tire met the requirements of national standard,the durability was comparable,the strength and high-speed performance were slightly improved,the rolling resistance was decreased,and tire weight was reduced. |
