| 中文摘要: |
| 介绍28L－26 26PR LS-2无内胎林业子午线轮胎的设计。结构设计：外直径 1 612 mm，断面宽 696 mm，行驶面宽度 677 mm，胎圈着合直径 660 mm，胎圈着合宽度 635 mm，断面水平轴位置（H?1/H?2） 0.63，胎面采用横向人字形花纹，花纹深度 57 mm，花纹饱和度 30%，花纹周节数 16。施工设计：胎面采用三方四块结构，胎体采用12层1400 dtex/3锦纶66帘布，缓冲层采用0.37＋6×0.32 ST钢丝帘线，采用胶囊反包成型机成型、胶囊定型硫化机硫化。成品性能测试结果表明，成品轮胎的外缘尺寸和物理性能均达到设计及相应国家标准要求。 |
| 英文摘要: |
| The design of 28L－26 26PR LS-2 tubeless forestry radial tire was introduced.In the structure design，the following parameters were taken：overall diameter?1 612 mm，cross-section width?696 mm，width of running surface?677 mm，bead diameter at rim seat?660 mm，bead width at rim seat?635 mm，maximum width position of cross-section（H?1/H?2）?0.63，with a transverse herringbone pattern design for tread，pattern depth?57 mm，block/total ratio?30%，and number of pattern pitches?16 sections.In the construction design，the following parameters were taken：using three-formula and four-piece structure for tread，12 layers of nylon 66 cord for carcass，0.37＋6×0.32ST steel cord for breaker ply，capsule reverse package building machine to build tire，and bladder curing press to cure tire.The test results of finished tires showed that the inflated peripheral dimension and physical properties of the tires met the requirements of design and corresponding national standards. |
