| 中文摘要: |
| 介绍12.00R20 20PR矿山全钢载重子午线轮胎的设计。结构设计：外直径 1 135 mm，断面宽 310 mm，行驶面宽度 245 mm，行驶面弧度高 8.6 mm，胎圈着合直径 511 mm，胎圈着合宽度 230 mm，断面水平轴位置（H1/H2） 1.01，胎面采用以横向宽沟为主的大块花纹，横向宽沟采用仿人类脚印以及向沟底阶梯过渡的设计，花纹深度 25 mm，花纹饱和度 70%，花纹周节数 33。施工设计：胎面采用三方三块结构，1#和2#带束层采用3＋8×0.35ST钢丝帘线，3#带束层采用5×0.38HI钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线，胎体采用3＋9＋15×0.225ST无外缠丝钢丝帘线。采用一次法成型机成型、双模定型硫化机硫化。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均满足相应设计和国家标准要求。 |
| 英文摘要: |
| The design on 12.00R20 20PR all-steel truck radial tire for mining was introduced.In the structure design，the following parameters were taken：overall diameter 1 135 mm，cross-section width 310 mm，width of running surface 245 mm，arc height of running surface 8.6 mm，bead diameter at rim 511 mm，bead width at rim seat 230 mm，maximum width position of cross-section（H1/H2） 1.01，the tread adopted a large pattern with main transverse wide grooves，and the transverse wide grooves were designed to imitate human footprints and transition to the bottom of the grooves in a stepped manner，pattern depth 25 mm，block/total ratio 70%，and number of pattern pitches 33.In the construction design，the following processes were taken：three-formula and three-piece structure for tread，3＋8×0.35ST steel cord for 1# and 2# belt，5×0.38HI steel cord for 3# belt，3×7×0.20HE steel cord for 0° belt，3＋9＋15×0.225ST steel cord without wrapped steel wire for carcass，using one stage building machine to build tire and dual-mode shaping press to cure tire.It was confirmed by the tests of the finished tire that，the inflated peripheral dimension，strength and endurance met the requirements of corresponding design and national standards. |
