Development of OE Low Rolling Resistance Tire by Applying New Structure and New Materials

应用新结构、新材料开发配套12R22.5 C600低滚动阻力轮胎。应用超高强度骨架材料,胎体采用0.17+5×0.215+10×0.235CCST钢丝帘线,带束层采用4+3×0.35ST钢丝帘线,钢丝包布采用0.17+5×0.215+10×0.235CCST钢丝帘线;优化配方设计,胎面胶采用低滚动阻力胶料,基部胶采用低滞后损失胶料;优化胎冠弧设计以及胎肩和胎圈部位材料分布。成品轮胎的充气外缘尺寸符合国家标准要求,耐久性能良好,滚动阻力达到欧盟标签C级,满足客户的需求,轮胎装车后行驶里程达到20万km,与普通轮胎相比,平均每百公里可节油1.13 L。

The original equipment(OE)12R22.5 C600 low rolling resistance tire developed by applying new structure and new materials.Ultra-high-strength skeleton materials were applied to prepare the tire,using 0.17+5×0.215+10×0.235CCST steel cord for carcass,4+3×0.35ST steel cord for belt,0.17+5×0.215+10×0.235CCST steel cord for steel wire cloth.The formula design was optimized,with low rolling resistance tread compound and low hysteresis loss base compound.The crown arc design and the material distribution at the shoulder and bead were optimized.The inflated peripheral dimension of finished tires met the requirements of the national standards,the durability was good,and the rolling resistance reached the EU label level C,meeting the needs of customers.After the tire was loaded,the driving mileage reached 200000 km,and the average fuel saving per 100 km was 1.13 L compared with ordinary tire.
