| 中文摘要: |
| 对12.00一20 18PR载重斜交轮胎的结构进行了优化设计。采取的主要措施是:改进轮胎外轮廓、胎面花纹和胎圈结构胎体采用12层1400dtex/2加密尼龙帘布替代10层1870dtex/2尼龙帘布;缓冲层采用单层宽缓冲层帘布替代两层窄缓冲层帘布;提高反包高度;加大三角胶;增大油皮胶厚度。优化设计后，轮胎的各项性能符合国家标准，超载能力有明显的改善。 |
| 英文摘要: |
| The design of 12.00一20 18PR bias truck tire structure was optimized. The major measures were as follows:the outer profile of tire,the tread patterns and the bead structure were modified;twelve plies of 1400dtex/2 densified nylo n cord were used instead of ten plies of 1870dtex/ 2 nylon cord in the carcass;the single wide cushion ply was replaced for the two narrow cushion plies;the bead filler
was enlarged;and the thickness of insulating compound was increased. The performance criteria of optimized tire met with the requirements specified in the national standards and the overload capacity was
significantly improved. |
