| 中文摘要: |
| 介绍12R22.5全钢载重子午线轮胎的设计。结构设计：轮胎外直径1 083 mm，轮胎断面宽293 mm，行驶面宽度238 mm，行驶面弧度高8 mm，胎圈着合直径570 mm，胎圈着合宽度228 mm，断面水平轴位置（H1/H2）0.950 6，花纹深度17 mm，花纹饱和度73.6%，采用3条曲折主花纹沟设计。施工设计：胎面采用两方两块结构，胎体采用3+9+15×0.175+0.15钢丝帘线，1#，2#和3#带束层采用3×0.20+6×0.35HT钢丝帘线，4#带束层采用3×4×0.22HE钢丝帘线；采用三鼓一次法成型机成型，双模定型硫化机硫化。成品轮胎性能试验结果表明，轮胎充气外缘尺寸、强度性能和耐久性能符合国家标准要求，速度性能和胎圈耐久性能符合企业标准要求。 |
