| 中文摘要: |
| 介绍9.00-20NHS 14PR OB502工业车辆轮胎的设计。结构设计：外直径 1 006 mm，断面宽 232 mm，行驶面宽度 210 mm，行驶面弧度高 5.5 mm，胎圈着合直径 514 mm，胎圈着合宽度 178 mm，断面水平轴位置（H1/H2） 0.921 9，采用横向块状花纹，花纹深度 25 mm，花纹饱和度 76%，花纹周节数 30。施工设计：胎面采用三方四块结构，胎体采用8层高强度1400dtex/3锦纶6浸胶帘布，缓冲层采用2层1400dtex/3V3锦纶6浸胶帘布，采用胶囊反包成型机成型、B型胶囊硫化机硫化。成品轮胎试验结果表明，轮胎的充气外缘尺寸和物理性能均符合相应设计和国家标准要求。 |
