| 中文摘要: |
| 介绍LT265/70R17 121/118Q 10PR MT半钢子午线轮胎的设计。结构设计：外直径 804 mm，断面宽 268 mm，行驶面宽度 206 mm，行驶面弧度高 10.8 mm，胎圈着合直径 435.2 mm，胎圈着合宽度 228.6 mm，断面水平轴位置（H1/H2） 0.932。施工设计：胎面采用三方四块结构，冠带层采用2层1400dtex/2锦纶66浸胶帘布，带束层采用2层2＋7×0.28HT钢丝帘线，胎体采用1670dtex/2-100EPD高模量低收缩聚酯帘线，采用二次法成型机成型、B型液压硫化机和氮气硫化工艺硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均符合设计要求。 |
| 英文摘要: |
| The design on LT265/70R17 121/118Q 10PR MT steel-belted radial tire was introduced.In the structure design，the following parameters were taken：overall diameter?804 mm，cross-sectional width?268 mm，width of running surface 206 mm，arc height of running surface 10.8 mm，bead diameter at rim seat?435.2 mm，bead width at rim seat?228.6 mm，maximum width position of cross–section
（H1/H2）?0.932.In the construction design，the following processes were taken：using three-formula and four-piece structur for tread，two layers of 1400dtex/2 nylon 66 dipped cord fabric for crown and two layers of 2＋7×0.28HT steel cord for belt，1670dtex/2-100EPD high modulus and low shrinkage polyester cord for carcass，and using the two-stage building machine to build tire，B-type hydraulic vulcanizing machine and nitrogen vulcanization process to cure tire.The test results of finished tire showed that，the inflated peripheral dimention，strength performance, durability and high-speed performance of the tire met the requirements of design. |
