中文摘要:
      介绍工业用18.4-26 12PR R 4A无内胎农业轮胎的设计。结构设计：外直径　1 430 mm，断面宽　425 mm，行驶面宽度　385 mm，弧度高　45 mm，胎圈着合直径　662 mm，胎圈着合宽度　390 mm，断面水平轴位置(H1/H2)0.67，采用R 4A胎面花纹，花纹深度　28.5 mm，花纹饱和度　33%，花纹周节数　19。施工设计：胎面采用两方三块结构；缓冲层采用2层1400dtex/2V2锦纶6浸胶帘布，胎体采用6层1400dtex/2锦纶6浸胶帘布，钢丝圈采用Φ1 mm的19#回火胎圈钢丝，采用半鼓式成型机成型、硫化罐硫化。成品轮胎试验结果表明，轮胎的充气外缘尺寸、物理性能和帘线角度均符合相应国家标准和企业标准要求。
英文摘要:
      The design of 18.4-26 12PR R 4A tubeless agriculture tire for industrial applications was described.In the structure design，the following parameters were taken:overall diameter　1 430 mm，cross-sectional width　425 mm，width of running surface　385 mm，height of running surface　45 mm，bead diameter at rim seat　662 mm，bead width at rim seat　390 mm，maximum width position of cross－section(H1/H2)　0.67，R 4A tread pattern，pattern depth　28.5 mm，block/total ratio　33%，and total number of pitches　19.In the construction design，two formula and three piece tread was designed，2 layers of 1400dtex/2 dipped nylon 6 cord were applied for breaker ply，6 layers of 1400dtex/2 dipped nylon 6 cord were used for carcass ply，and Φ1 mm 19# tempered bead wire was used.The tire was built using the semi drum building machine and cured in an autoclave.It was confirmed by the tests of the finished tire that，the peripheral dimension，physical properties and cord angle met the requirements of relative national and enterprise standards.
