| 中文摘要: |
| 介绍195/55R20轿车子午线轮胎的设计。结构设计：外直径 718 mm，断面宽 208 mm，行驶面宽度 156 mm，行驶面弧度高 8.57 mm，胎圈着合直径 511.5 mm，胎圈着合宽度 172 mm，断面水平轴位置（H1/H2） 1.0，胎面采用非对称变节距花纹设计，花纹深度 7.5 mm，花纹饱和度 67%，花纹周节数 68。施工设计：胎面胶采用采用白炭黑、硅烷偶联剂及溶聚丁苯橡胶的配方设计，2层带束层均采用2＋2×0.25HT钢丝帘线，胎体采用1层1440dtex/2DSP聚酯帘布，采用一次法成型机成型、B型双模液压硫化机硫化。成品轮胎性能试验结果表明，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国家标准要求。 |

| The design on 195/55R20 passenger car radial tire was introduced.In the structure design，the following patameters were taken：overal diameter 718 mm，cross-section width 208 mm，width of running surface 156 mm，arc height of running surface 8.57 mm，bead diameter at rim seat 511.5 mm，bead width at rim seat 172 mm，maximun width position of cross-section（H1/H2） 1.0，using asymmetric variable pitch pattern design for tread，pattern depth 7.5 mm，block/total ratio 67%，and number of pattern pitches 68.In the construction design，the following processes were taken：the formula design using silica，silane coupling agent，and solution polymerized butadiene styrene rubber for tread compound，two layers of 2＋2×0.25HT steel cord fabric for belt，one layer of 1440dtex/2DSP polyester cord fabric for carcass，using one step building machine to build tire and B-type dual-mode hydraulic vulcanizing press to cure tire.The performance test results of the finished tire showed that the inflated peripheral dimension，strength performance，high-speed performance，and durability of the tire all met the requirements of corresponding design and national standard. |
