| 中文摘要: |
| 介绍155R13LT半钢轻型载重子午线轮胎的设计。结构设计：外直径 575.5 mm，断面宽 154 mm，行驶面宽度 110 mm，行驶面弧度高 5.78 mm，胎圈着合直径 328.2 mm，胎圈着合宽度 127 mm，断面水平轴位置（H1/H2） 0.883 5，胎面采用3条曲折型主沟花纹设计，花纹深度 8.2 mm，花纹饱和度 75.41%，花纹周节数 60。施工设计：胎面采用三方四块结构，带束层采用2层2＋2×0.35HT钢丝帘线，胎体采用2层1440dtex/2聚酯纤维帘线，采用二次法成型机成型、双模液压热板式硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、高速性能和耐久性能均满足国家及企业标准要求。 |
| 英文摘要: |
| The design on 155R13LT steel-belted light truck and bus radial tire was introduced.In the structure design，the following parameters were taken：overall diameter?575.5 mm，cross-sectional width?154 mm，width of running surface 110 mm，arc height of running surface 5.78 mm，bead diameter at rim seat?328.2 mm，bead width at rim seat?127 mm，and maximum width position of cross–section
（H1/H2）?0.883 5.The tread adopted 3 main groove curve design，pattern depth 8.2 mm and block/total ratio 75.41%，number of pattern pitchs 60.In the construction design，the following processes were taken：using three-formula and four-piece structure for the tread，two layers of 2＋2×0.35HT steel cord for the belt，two layers of 1440dtex/2 polyester fiber cord for the carcass，and using two-stage building machine to build tires and double mold hydraulic hot plate vulcanizing machine to cure tires.The test results of finished tire showed that，the inflated peripheral dimention，strength performance，high-speed performance and durability of the tires met the requirements of national and enterprise standards. |
