紧密型钢丝帘线在全钢轻载子午线轮胎中的应用

Application of compact steel cord in all-steel radial light truck tire

采用 12× 0 2 2 +1CCHT紧密型钢丝帘线替代 3 +9+15× 0 175 +1层状结构钢丝帘线作为胎体骨架材料试生产全钢轻载子午线轮胎。 8 2 5R16LT轮胎成品试验结果表明 ,采用紧密型钢丝帘线生产的全钢轻载子午线轮胎性能略优于层状结构钢丝帘线轮胎 ,而且成本较低。

CCHT compact steel cord was used as carcass ply cord instead of 3+9+15×0.175+1 layer construction steel cord in the pilot production of all-steel radial light truck tire.The test results of 8.25R16LT tire showed that the tire made of 12×0.22+1CCHT cord was somewhat superior to that made of 3+9+15×0.175+1 layer construction cord in terms of performance;and the cost of the former was lower than the latter.
