| 中文摘要: |
| 介绍19.5LR24 IND无内胎农业子午线轮胎的设计。结构设计：外直径 1 301 mm，断面宽 500 mm，行驶面宽度 442 mm，行驶面弧度高 22 mm，胎圈着合直径 612 mm，胎圈着合宽度 445 mm，断面水平轴位置（ H1/ H2） 0.744 3，采用有向花纹，花纹深度 38 mm，花纹饱和度 28.8%，花纹周节数 18。施工设计：采用缠绕胎面，带束层采用4层1400dtex/3锦纶66浸胶帘布（低负荷）或2层3×0.2＋6×0.35HT钢丝帘线（高负荷），胎体采用3层2200dtex/2 DSP聚酯帘布，采用成型机成型、蒸锅式双模硫化机硫化。成品性能试验结果表明，成品轮胎的外缘尺寸、物理性能和耐久性能满足相关标准要求。 |

| The design on19.5LR24 IND tubeless agriculture radial tire was described.In the structure design，the following parameters were taken：overall diameter?1 301 mm，cross-sectional width?500 mm，width of running surface 442 mm，arc height of running surface 22 mm，bead diameter at rim seat?612 mm，bead width at rim seat?445 mm，maximum width position of cross–section（H1/ H2）0.744 3，using directed pattern，pattern depth?38 mm，block/total ratio?28.8%，and number of pattern pitches?18.In the construction design，the following processes were taken：using winding tread，using 4 layers of 1400dtex/3 dipped nylon 66 cord for belt（low load） or 2 layers of 3×0.2＋6×0.35HT steel cord for belt（high load），3 layers of 2200dtex/2 DSP polyester cord for carcass，using building machine to build tires，and steamer-type double-mold press to cure tires．It was confirmed by the finished tire test that，the inflated peripheral dimension，physical properties and endurance met the requirements of relevant standards. |
