| 介绍11.00R20 18PR全钢轻型载重子午线轮胎的设计。结构设计：轮胎外直径 1 080.3 mm，断面宽度 288 mm，行驶面宽度 195 mm，行驶面弧度高 7.0 mm，胎圈着合直径 511 mm，胎圈着合宽度 216 mm，断面水平轴位置（H1/H2） 1.16；胎面花纹采用等节距设计，花纹深度 14 mm，花纹饱和度 80%。施工设计：胎面采用热喂料和冷喂料双复合挤出机挤出，胎体采用3＋9＋15×0.22HT钢丝帘线，1#和2#带束层采用3＋8×0.33HT钢丝帘线，3#带束层采用5×0.30HE钢丝帘线，0°带束层采用3×7×0.20H钢丝帘线，六角形钢丝圈采用直径1.83 mm钢丝；采用三鼓式一次法成型机成型，双模B型热板硫化机硫化。充气轮胎的外缘尺寸、强度性能、耐久性能符合设计和国家标准要求。 |
| 英文摘要: |
| This paper introduces the design of 11.00R20 18PR steel cord light truck radial tire.In the structural design，overall diameter was 1 080.3 mm，width of cross section was 288 mm，width of running surface was 195 mm，arc height of running surface was 7.0 mm，bead diameter at rim seat was 511 mm，bead width at rim seat was 216 mm，maximum width position of cross-section（H1/H2） was 1.16，equal pitch pattern was used，pattern depth was 14 mm，and block/total ratio was 80%.In the construction design，tread was co-extruded using both hot feed and cold feed，3＋9＋15×0.22HT steel cord was applied in the carcass ply，3＋8×0.33HT steel cord was used in the 1# and 2# belt layers，5×0.30HE steel cord was used in the 3# belt layer，3×7×0.20H steel cord was applied in the 0° belt，and Φ1.83 mm steel wire was applied in the bead wire.The tire was formed using three-drum forming machine，and cured with type-B hot plate vulcanization machine. It was confirmed by the finished tire test that，the inflated peripheral dimension，strength performance and endurance performance reached the requirements of the design and national standard. |
