2+4×0.17UT钢丝帘线在半钢子午线轮胎带束层中的应用

Application of 2+4×0. 17UT Steel Cord in Belt of Steel-belted Radial Tire

研究2+4×0.17UT钢丝帘线在185/55R15半钢轿车子午线轮胎带束层中的应用。与2+2×0.25HT钢丝帘线相比,2+4×0.17UT钢丝帘线直径小、刚度低、强度高,以其替代2+2×0.25HT钢丝帘线用于185/55R15半钢轿车子午线轮胎带束层,成品轮胎压穿强度得以保持,滚动阻力和噪声降低,并在满足轮胎性能要求的前提下,大幅减小了轮胎的带束层质量。

The application of 2＋4×0. 17 UT steel cord in the belt layer of 185/55R15 steel-belted radial tire was investigated. Compared with 2＋2×0. 25 HT steel cord,2＋4×0. 17 UT steel cord possessed smaller diameter,lower rigidity and higher strength. Using 2＋4×0. 17 UT steel cord instead of 2＋2×0. 25 HT steel cord in the belt of steel-belted radial tire,the compressive strength of finished tire changed little,the rolling resistance and noise decreased,the belt weight was reduced significantly,and at the same time the performance requirements of tire were all met.
