| 中文摘要: |
| 介绍265/35R22 102W XL超高性能半钢子午线轮胎的设计。结构设计：外直径 742 mm，断面宽 262 mm，行驶面宽度 236 mm，行驶面弧度高 10.1 mm，胎圈着合直径 562.7 mm，胎圈着合宽度 259 mm，断面水平轴位置（H1/H2） 0.91，采用非对称花纹设计，花纹深度 8 mm，花纹饱和度 75.2%，花纹周节数 27。施工设计：采用双复合挤出胎面，带束层采用2层1×2×0.30ST钢丝帘线，胎体采用2层1440dtex/2-110高模量低收缩聚酯帘线，采用一次法成型机成型、液压硫化机硫化。成品性能试验结果标明：成品轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均符合相应设计和企业标准要求。 |
| 英文摘要: |
| The design on 265/35R22 102W XL ultra-high performance steel-belt radial tire was described.In the structure design，the following parameters were taken：overall diameter?742 mm，cross-sectional width?262 mm，width of running surface 236 mm，arc height of running surface 10.1 mm，bead diameter at rim seat?562.7.6 mm，bead width at rim seat?259 mm，maximum width position of cross–section（H1/H2）?0.91，using asymmetric pattern design，pattern depth?8 mm，block/total ratio?75.2%，and number of pattern pitches?27.In the construction design，the following processes were taken：using double compound extrusion tread，two layers of 1×2×0.30ST steel cord for belt，two layers of 1440 dtex/2-110 high modulus and low shrinkage polyester cord for carcass，using one-step building machine to build tires，and hydraulic vulcanizing press to cure tires.The test results of finished tire showed that，the inflated peripheral dimention，strength，durability and high speed performance of finished tire met the requirements of corresponding design and enterprise standards. |
