| 中文摘要: |
| 介绍7.00R16 14PR全钢轻型载重子午线轮胎的设计。结构设计：外直径 773.6 mm，断面宽 198 mm，行驶面宽度 156 mm，行驶面弧度高 6.1 mm，胎圈着合直径 403 mm，胎圈着合宽度 154 mm，断面水平轴位置（H1/H2） 1.16，采用条形花纹设计，花纹周节数 76，花纹深度 12 mm，花纹饱和度 80.5%。施工设计：胎体采用3+9×0.22HT钢丝帘线，带束层采用3层3×0.20+6×0.35HT钢丝帘布；采用三鼓一次法成型机成型，双模B型硫化机硫化。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、耐久性能和高速性能均符合相应设计和国家标准要求。 |
| 英文摘要: |
| The design of 7.00R16 14PR light truck and bus radial tire was described.In the structure design，the following parameters were taken：overall diameter 773.6 mm，cross-sectional width 198 mm，width of running surface 156 mm，height of running surface 6.1 mm，bead diameter at rim seat 403 mm，bead width at rim seat 154 mm，maximum width position of cross-section （H1/H2） 1.16，strip pattern，total number of pitches 76，pattern depth 12 mm，and block/total ratio 80.5%.In the construction design，the following processes were taken：3+9×0.22HT steel cord for carcass ply，3 layers of 3×0.20+6×0.35HT steel cord for belt ply；using three drum single stage building machine to build tires，and using double mold B-type curing press to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension，strength performance，endurance performance and high speed performance met the requirements of relative design and national standard. |
