| 中文摘要: |
| 介绍新能源中型巴士专用10R22.5全钢载重子午线轮胎的设计。结构设计：外直径 1 020 mm，断面宽 260 mm，行驶面宽度 203 mm，行驶面弧度高 6.3 mm，胎圈着合直径 569.5 mm，胎圈着合宽度 203 mm，断面水平轴位置（ H/1/H/2） 0.846 3，胎面采用4条纵向直线花纹主沟设计，花纹深度 15.5 mm，花纹饱和度 78.39%，花纹周节数 63。施工设计：采用双复合挤出胎面，带束层采用3层3×0.20＋6×0.35HT钢丝帘线，胎体采用3×0.24/9×0.225CCST钢丝帘线，采用侧包冠成型工艺，采用液氮热板式硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能达到国家标准和企业标准要求。 |
| 英文摘要: |
| The design on 10R22.5 truck and bus radial tire for new energy medium bus was described.In the structure design，the following parameters were taken：overall diameter 1 020 mm，cross-sectional width?260 mm，width of running surface 203 mm，arc height of running surface 6.3 mm，bead diameter at rim seat?569.5 mm，bead width at rim seat?203 mm，maximum width position of cross–section（ H/1/H/2）
?0.846 3，using 4 longitudinal line main grooves tread patterns design，pattern depth?15.5 mm，block/total ratio?78.39%，and number of pattern pitches?63.In the construction design，the following processes were taken：using double composite extruded tread，3 layers 3×0.20＋6×0.35HT steel cord for belt，3×0.24/9×0.225CCST steel cord for carcass，adopting the molding process of side crowning for building and liquid nitrogen hot plate curing press for curing.The results of finished tire performance test showed that the inflated peripheral dimention，strength performance，durability and high-speed performance of the tire met the requirements of national standards and enterprise standards. |
