| 中文摘要: |
| 介绍9.5R17.5 14PR全钢载重子午线轮胎的设计。结构设计：外直径 838 mm，断面宽 238 mm，行驶面宽度 176 mm，行驶面弧度高 6 mm，胎圈着合直径 442.5 mm，胎圈着合宽度 172 mm，断面水平轴位置(H1/H2) 1.018，花纹深度 14 mm，花纹饱和度 74.15%，花纹周节数 61，采用曲折花纹设计。施工设计：胎体采用3+9×0.22+0.15钢丝帘线，1#和2#带束层采用3×0.20+6×0.35HT钢丝帘线，3#带束层采用5×0.30HI钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线；采用两鼓一次法成型机成型，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和强度性能符合相应设计和国家标准要求，耐久性能符合企业标准要求。 |

| The design of 9.5R17.5 14PR truck and bus radial tire was described.In structure design，the following parameters were taken：overall diameter 838 mm，cross-sectional width 238 mm，width of running surface 176 mm，height of running surface 6 mm，bead diameter at rim seat 442.5 mm，bead width at rim seat 172 mm，cross-sectional level ratio (H1/H2) 1.018，pattern depth 14 mm，block/groove ratio 71.15%，pattern circular pitch 61，with the design of zigzag pattern.In construction design，the following processes were taken：3+9×0.22+0.15 steel cord for carcass ply，3×0.20+6×0.35HT steel cord for 1# and 2# belt ply，5×0.30HI steel cord for 3# belt ply，3×7×0.20HE steel cord for 0° belt ply；using single stage two-drum building machine to build tires，and using curing press to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension and strength performance met the requirements of relative design and national standard，and the endurance performance met the requirements of enterprise standard. |
