带束层钢丝帘线对半钢子午线轮胎性能的影响

Effect of Belt Steel Cord on Performance of Steel-belted Radial Tire

通过成品轮胎室内试验及滚动阻力、静态刚性、接地印痕、六分力和动态冲击特性试验,研究带束层钢丝帘线对半钢子午线轮胎性能的影响。结果表明:3种带束层钢丝帘线成品轮胎的充气外缘尺寸、强度性能、脱圈阻力、高速性能和耐久性能均符合国家标准要求;带束层钢丝帘线主要影响轮胎滚动阻力、接地印痕形状和动态冲击特性,对静态刚性及六分力影响较小。

In this study,the effect of steel cord in the belt on the performance of steel-belted radial tire was studied by laboratory test of the finished tires,and tests of the rolling resistance,static rigidity,footprint,forces and moments,and dynamic impact characteristics.The results showed that the inflation peripheral dimension,strength performance,bead unseating resistance,high-speed performance and durability of the finished tires with three kinds of steel cord in the belt all met the requirements of national standards.The steel cord in the belt mainly affected the rolling resistance,the shape of the footprint and the dynamic impact characteristics of the tire,but had little influence on the static rigidity and forces and moments.
