【摘要】 以12.00R20 18PR载重子午线轮胎为例介绍中短途载重子午线轮胎技术改进,重点提高胎圈性能。通过采取降低胎体帘布反包高度,增大钢丝包布宽度,在钢丝包布内外各增加2层锦纶包布,同时对上下三角胶配方进行优化设计等措施,大幅提高了胎圈耐久性能。更多还原

【Abstract】 The truck and bus radial tire for short and middle distance was improved by taking 12.00R20 18PR tire as an example.It was found that the durability of the bead was greatly improved by reducing the turn-up height of carcass cord,increasing the width of steel chafer,adding 2layers of nylon chafers on each side of steel chafer,and optimizing the formula of upper and lower bead filler.更多还原
