| 中文摘要: |
| 介绍405/70-24 14PR EMR 1宽基轮胎的设计。结构设计：外直径 1 121 mm，断面宽 402 mm，行驶面宽度 380 mm，行驶面弧度高 -4 mm，胎圈着合直径 611 mm，胎圈着合宽度 330 mm，断面水平轴位置（H1/H2) 0．746，花纹深度 28 mm，花纹饱和度 41．4%，花纹周节数 22。施工设计：胎面采用两方三块结构，胎体采用6层2100dtex/2锦纶66浸胶帘布，缓冲层采用2层1400dtex/2锦纶66浸胶帘布；采用LCX 3B型成型机成型，立式硫化罐硫化。成品性能试验结果表明，成品轮胎的充气外缘尺寸和物理性能均符合国家标准及相关设计要求。 |
| 英文摘要: |
| The design of 405/70-24 14PR EMR 1 wide base tire was described.In the structure design，the following parameters were taken：overall diameter 1 121 mm，cross－sectional width 402 mm，width of running surface 380 mm，height of running surface -4 mm，bead diameter at rim seat 611 mm，bead width at rim seat 330 mm，maximum width position of cross section (H1/H2) 0.746，pattern depth 28 mm，block/total ratio 41.4%，and total number of pitches 22.In the construction design，the following processes were taken：two formula and three piece extruded tread，6 layers of 2100dtex/2 dipped nylon 66 cord for carcass ply，2 layers of 1400dtex/2 dipped nylon 66 cord for break ply；using LCX 3B building machine to bulid tires，and using vertical autoclave to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension and physical properties met the requirements of national standards and relative design. |
