| 中文摘要: |
| 介绍235/65R16C 121/119R 10PR VAN类车辆全天候子午线轮胎的设计。结构设计：外直径 710 mm，断面宽 250 mm，行驶面宽度 190 mm，行驶面弧度高 10.31 mm，胎圈着合直径 404.6 mm，胎圈着合宽度 203 mm，断面水平轴位置（H1/H2） 1.0，胎面采用单导向花纹设计，花纹深度 9.7 mm，花纹周节数 60，花纹饱和度 65.1%，胎侧增加防撞击能量条设计。施工设计：胎面采用三复合结构，胎体采用2层2200dtex/2聚酯浸胶帘布，带束层采用3×0.20＋6×0.35HT钢丝帘线，采用二次法成型机成型，双模热板式B型液压硫化机硫化。成品轮胎试验结果表明，轮胎的充气外缘尺寸、强度性能、高速性能和耐久性能均达到相应设计和企业标准要求。 |
