| 中文摘要: |
| 介绍商用电动汽车专用12R22.5轮胎的设计。结构设计：外直径 1 083 mm，断面宽 302 mm，行驶面宽度 238 mm，行驶面弧度高 5 mm，胎圈着合直径 571 mm，胎圈着合宽度 244 mm，断面水平轴位置（ H1/ H2） 0.965，花纹沟采用变角度平顺设计，花纹深度 18.5 mm，花纹饱和度 83.5%，花纹周节数 72。施工设计：胎面采用三复合挤出，胎体采用3×0.24/9×0.225CCHT钢丝帘线，4层带束层均采用3＋8×0.33HT钢丝帘线，采用三鼓一次法成型机成型、双模定型硫化机硫化。成品轮胎的充气外缘尺寸、强度性能、耐久性能、高速性能和滚动阻力系数均符合国家标准和企业标准要求。 |
| 英文摘要: |
| The design of 12R22.5 tubeless all-steel radial tire specially for commercial electric vehicle was introduced.In the structure design，the following parameters were taken：overall diameter?1 083 mm，cross-sectional width?302 mm，width of running sruface?238 mm，arc height of running surface?5 mm，bead diameter at rim seat?571 mm，bead width at rim seat?244 mm，maximum width position of cross-section（ H1/ H2）?0.965，using variable-angle smooth design for the tread groove，pattern depth?18.5 mm，block/tatal ratio?83.5%，and number of pattern pitches?72.In the construction design，the following processes were taken：three-compound extrusion for tread，3×0.24/9×0.225 CCHT steel cord for carcass，3＋8×0.33 HT steel cord for four-layer belt，using three-drum one-stage building machine to build tire and double-mold shaping press to cure tire.The inflated peripheral dimension，strength，durability，high-speed performance and rolling resistance coefficient of the finished tire all met the requirements of national standards and enterprise standards. |
