中文摘要:
      介绍11.00R20 16PR长途耐久型全钢载重子午线轮胎的设计。结构设计：外直径　1 081 mm，断面宽　288 mm，行驶面宽度　236 mm，行驶面弧度高　6.8 mm，胎圈着合直径　508 mm，胎圈着合宽度　216 mm，断面水平轴位置（H1/H2）　1.091，花纹深度　15.5 mm，花纹饱和度　72.47%，采用4条纵向曲折条形花纹设计。施工设计：胎面采用两方两块结构，胎体采用3+9×0.22+0.15HT钢丝帘线，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。采用一次法成型机成型，双模蒸汽硫化机硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸、强度性能和耐久性能均符合相应设计和国家标准要求，高速性能符合企业标准要求。
英文摘要:
      The design of 11.00R20 16PR long-distance and endurance truck and bus radial tire was described.In the structure design，the following parameters were taken：overall diameter　1 081 mm，cross-sectional width　288 mm，width of running surface　236 mm，height of running surface　6.8 mm，bead diameter at rim seat　508 mm，bead width at rim seat　216 mm，maximum width position of cross-section （H1/H2）　1.091，pattern depth　15.5 mm，block/total ratio　72.47%，and 4 longitudinal zigzag pattern grooves.In the construction design，the following processes were taken：two-formula and two-piece extruded tread，3+9×0.22+0.15HT steel cord for carcass ply，3×0.20+6×0.35HT steel cord for 1# belt ply，3+8×0.33HT steel cord for 2# and 3# belt ply，3×4×0.22HE steel cord for 4# belt ply；using single stage building machine to build tires，and using double mold steam vulcanizer to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension，strength performance and endurance performance met the requirements of relative design and national standard，and the high speed performance met the requirements of enterprise standard.
