中文摘要:

介绍235/55R17 99W轿车子午线轮胎的设计。结构设计：外直径　686 mm，断面宽　255 mm，行驶面宽度　188 mm，行驶面弧度高　9.8 mm，胎圈着合直径　435.7 mm，胎圈着合宽度　210.82 mm，断面水平轴位置（H₁/H₂）　1.02，采用4条宽大纵向主沟花纹，花纹深度　8.5 mm，花纹周节数　67，花纹饱和度　65.45%。施工设计：胎体采用2层1440dtex/2 DSP聚酯帘布，带束层采用3×0.30HT钢丝帘线；采用一次法成型机成型、双模液压硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸、强度性能、脱圈阻力、耐久性能、低气压性能和高速性能均符合国家标准要求，滚动阻力达到欧盟标签法B级要求。

英文摘要:

The design on 235/55R17 99W passenger car radial tire was described.In the structure design，the following parameters were taken：overall diameter　686 mm，cross-sectional width 　255 mm，width of running surface　188 mm，arc height of running surface　9.8 mm，bead diameter at rim seat　435.7 mm，bead width at rim seat　210.82 mm，maximum width position of cross-section（H₁/H₂）　1.02，using 4 wide longitudinal groove pattern，pattern depth　8.5 mm，number of pattern pitches　67，and block/total ratio　65.45%.In the construction design，the following processes were taken：2 layers of 1440dtex/2 DSP polyester cord for carcass，3×0.30HT steel cord for belts，using single stage building machine to build tire and double mold hydraulic curing press to cure tire.It was confirmed by the tests of the finished tire that，the inflated peripheral dimension，strength performance，bead unseating resistance，endurance，low pressure performance and high speed performance met the requirements of national standards，and the rolling resistance met the level B requirements of EU labelling act.
