| 中文摘要: |
| 介绍385/65R22.5宽基全钢载重子午线轮胎带束层结构优化设计。基于我公司轮胎外轮廓设计，带束层由4层结构改为3层带束层加2层0°带束层结构。改进后轮胎接地印痕更合理，接地面积增大5%，接地压力分布更均匀且平均压力更小，使成品轮胎耐久性试验时间延长25%。 |
| 英文摘要: |
| The design on the belt structure of 385/65R22.5 wide base truck and bus radial tire was optimized.The design was based on original tire outer profile,but the 4-layer belt structure was changed into 3 layers of belt and additional 2 layers of 0° belt.After the modification,the tire footprint was adjusted,the ground contact area increased 5%,the ground contact pressure distribution was more uniform and the average contact pressure was reduced,which could extend the endurance time of finished tire by 25%. |
