| 中文摘要: |
| 介绍12R22.5 18PR无内胎全钢载重子午线轮胎的设计。结构设计：外直径 1 080 mm，断面宽 302 mm，行驶面宽度 235 mm，行驶面弧度高 13.5 mm，胎圈着合直径 569.5 mm，胎圈着合宽度 241 mm，断面水平轴位置(H1/H2) 0.96，胎面采用4条纵向花纹沟设计，花纹深度 16 mm，花纹饱和度 78.8%，花纹周节数 95。施工设计：胎面采用两方两块结构，1#带束层采用3×0.20+6×0.35HT钢丝帘线，2#和3#带束层采用3+8×0.33HT钢丝帘线，4#带束层采用3×4×0.22HE钢丝帘线，胎体采用0.25+6+12×0.225HT钢丝帘线，采用三鼓成型机成型、热板式硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸和强度性能均符合相应设计和国家标准要求，耐久性能和高速性能符合企业标准要求。 |
| 英文摘要: |
| The design of 12R22.5 18PR tubeless truck and bus radial tire was described.In the structure design，the following parameters were taken:overall diameter 1 080 mm，cross-sectional width 302 mm，width of running surface 235 mm，height of running surface 13.5 mm，bead diameter at rim seat 569.5 mm，bead width at rim seat 241 mm，maximum width position of cross-sectional(H1/H2) 0.96，4 longitudinal pattern grooves，pattern depth16 mm，block/total ratio 78.8%，and number of pattern pitch 95.In the construction design，the following processes were taken:two formula and two piece tread，3×0.20+6×0.35HT steel cord for 1# belt，3+8×0.33HT steel cord for 2# and 3# belt，3×4×0.22HE steel cord for 4# belt，0.25+6+12×0.225HT steel cord for carcass ply，and using three drum building machine to build tires and hot press to cure tires.It was confirmed by the test of finished tires that，the inflated peripheral dimension and strength performance reached the requirements of the design and national standard，and the endurance and high speed perfor mance met the requirements of enterprise standard. |
