| 中文摘要: |
| 介绍11R22.5长途大巴子午线轮胎的设计。结构设计：外直径 1053 mm，断面宽 288 mm，行驶面宽度 226 mm，行驶面弧度高 6.5 mm，胎圈着合直径 569.5 mm，胎圈着合宽度 228 mm，断面水平轴位置（H1/H2） 0.86，胎面采用4条纵向花纹沟设计，花纹深度 17.5 mm，花纹饱和度 76%，花纹周节数 40。施工设计：胎面采用分层设计，1#和2#带束层采用3×0.20＋6×0.35HT钢丝帘线，3#带束层采用5×0.30HI钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线，胎体采用3＋9＋15×0.175＋0.15NT钢丝帘线，采用一次法成型机成型、热板式硫化机氮气硫化。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、耐久性能和高速性能等均达到国家标准和相应设计要求。 |

| The design on 11R22.5 long-distance bus radial tire was introduced.In the structure design，the following parameters were taken：overall diameter 1 053 mm， cross-sectional width 288 mm， width of running surface 226 mm，arc height of running surface 6.5 mm，bead diameter at rim seat 569.5 mm，bead width at rim seat 228 mm，maximum width position of cross-section（H1/H2） 0.86，using 4 longitudinal grooves for tread design，pattern depth 17.5 mm，block/total ratio 76%，and number of pattern pitches 40.In the construction design，the following processes were taken：layered design for tread，3×0.20＋6×0.35HT steel cord for 1# and 2# belt，5×0.30HI steel cord for 3# belt，3×7×0.20HE steel cord for 0° belt，3＋9＋15×0.175＋0.15NT steel cord for carcass，using one-stage building machine to build tire，and hot plate curing press with nitrogen to cure tire.It was confirmed by the finished tire test that，the inflated peripheral dimention，strength performance，endurance performance and high-speed performance met the national standard and requirements of corresponding design. |
