| 中文摘要: |
| 介绍455/45R22.5宽基无内胎全钢载重子午线轮胎的设计。结构设计：轮胎外直径980 mm，断面宽度455mm，行驶面宽度404 mm，胎圈着合直径569.5 mm，胎圈着合宽度390 mm，断面水平轴位置1.009，花纹以条形花纹为主，花纹饱和度76.6%。施工设计：胎体采用3+9+15×0.175+0.15HT钢丝帘线，带束层采用3+9+15×0.22+0.15，3+8×0.33HT和3×7×0.20HE钢丝帘线，成型采用三鼓一次法成型机，硫化采用B型硫化机。成品轮胎充气外缘尺寸、强度性能、耐久性能和速度性能达到设计要求。 |
| 英文摘要: |
| The design of 455/45R22.5 20PR wide base tubeless TBR tire was described. In the structure design， the following parameters were taken：overall diameter 980 mm， cross sectional width 455 mm， width of running surface 404 mm， bead diameter at rim seat 569.5 mm， bead width at rim seat 390 mm， maximum width position of cross section 1.009， strip pattern and block/total ratio 76.6%. In the construction design， the following processes were taken： 3+9+15×0.175+0.15HT steel cord for the carcass ply， 3+9+15×0.22+0.15 steel cord， 3+8×0.33HT steel cord and 3×7×0.20HE steel cord for the belt layer， single stage three-drum machine was used to shape tires and B-type vulcanizing machine to cure tires. It was confirmed by the tests of finished tires that the inflated peripheral dimension， strength， endurance performance and speed performance met the design requirements. |
