| 中文摘要: |
| 介绍雪地用途23.5R25全钢工程机械子午线轮胎的设计。结构设计：外直径 1 592 mm，断面宽 596 mm，行驶面宽度 530 mm，行驶面弧度高 24.5 mm，胎圈着合直径 630 mm，胎圈着合宽度 496 mm，断面水平轴位置（ H/1/H/2） 0.88，采用牵引型横向花纹沟设计，花纹块上带有3D钢片。施工设计：胎面采用雪地轮胎专用胎面胶配方，4层带束层结构，1# —3# 带束层采用3＋9＋15×0.22＋0.15NT钢丝帘线，4# 带束层采用4×6×0.25HE钢丝帘线，胎体采用3＋9＋15×0.22+0.15NT钢丝帘线，采用一次法成型机成型、单模蒸锅式硫化机硫化。成品轮胎试验结果表明，轮胎的充气外缘尺寸、物理性能和耐久性能均达到相应国家标准和企业标准要求。 |
