| 中文摘要: |
| 介绍550/60-22.5 I-3低断面无内胎农业轮胎的设计。结构设计：外直径 1 212 mm，断面宽 526 mm，行驶面宽度 440 mm，胎圈着合直径 568 mm，花纹深度 25 mm，花纹饱和度 55.7%，采用人字形花纹设计。施工设计：胎面胶采用两种配方胶料分别挤出，胎体采用4层1870dtex/2V1和2层1870dtex/2V2锦纶6帘布，立式胶囊硫化罐硫化。成品轮胎试验结果表明，轮胎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。 |
| 英文摘要: |
| A design of 550/60-22.5 I-3 low profile tubeless agricultural tire was described.In structure design，the following parameters were taken：overall diameter 1 212 mm，cross sectional width 526 mm，width of running surface 440 mm，bead diameter at rim seat 568 mm，pattern depth 25 mm，block/groove ratio 55.7%，with the design of chevron pattern block.In construction design，the following processes were taken：two types of rubber formulations in tread compound；4 layers 1870dtex/2V1 and 2 layers 1870dtex/2V2 nylon 6 cords for carcass ply，and bladder autoclave for tire vulcanization.The inflated overall dimension and the physical properties of finished tire met the requirements of national standards. |
