| 中文摘要: |
| 介绍12R22.5轻量化全钢载重子午线轮胎的设计。结构设计：外直径 1 074 mm，断面宽 295 mm，行驶面宽度 218 mm，行驶面弧度高 7 mm，胎圈着合直径 570 mm，胎圈着合宽度 240 mm，断面水平轴位置（H1/H2） 0.919，胎面采用4条曲折主花纹沟，花纹沟底采用V形开放结构，花纹深度 13 mm，花纹饱和度 79.87%，花纹周节数 67。施工设计：胎面采用两方三块结构，1#和2#带束层采用2＋7×0.30ST钢丝帘线，3#带束层采用5×0.35HI钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线，胎体采用3×0.24/9×0.225CCST钢丝帘线，采用一次法成型机成型、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、强度性能和耐久性能符合国家标准要求，高速性能和轮胎接地印痕分布符合企业标准要求，且质量小于同规格产品。 |

| The design on 12R22.5 lightweight all-steel truck and bus radial tire was introduced.In the structure design，the following paramemers were taken：overall diameter 1 074 mm，cross-section width 295 mm，width of running surface 218 mm，arc height of running surface 7 mm，bead diameter at rim seat 570 mm，bead width at rim seat 240 mm，maximum width position of cross-section（H1/H2） 0.919，four tortuous main pattern grooves for tread with V-shaped opening structure at the groove bottom，pattern depth 13 mm，block/total ratio 79.87%，and number of pattern pitches 67.In the construction design，the following processes were taken：two-formula and three-piece structure for tread，2＋7×0.30ST steelcord for 1# and 2# belt，5×0.35HI steel cord for 3# belt，3×7× 0.20HE steel cord for 0° belt，3×0.24/9×0.225CCST steel cord for carcass，using one stage building machine to build tire and vulcanization press to cure tire.The performance test results of the finished tire showed that the inflated peripheral dimension，strength，and durability of the tire met the requirements of national standards，the high-speed performance and grounding mark distribution met the requirements of enterprise standards，and the mass was lower than that of the same specification products. |
