| 中文摘要: |
| 介绍二段成型全地形车（UTV）子午线轮胎的开发。在对样胎配置进行分析的基础上，确定28×10R14 UTV子
午线轮胎采用胎体＋带束层＋冠带层的结构，具体配置为：胎体骨架材料 930dtex/2锦纶66帘线，胎体胎冠角 20°；带
束层骨架材料 930dtex/2锦纶66帘线，带束层胎冠角 65°；冠带层骨架材料 1400dtex/2锦纶66帘线，一字缠绕，交叠5
mm；钢丝圈 Φ0. 96 mm钢丝，5×4排列；三角胶尺寸（高×宽） 35 mm×5 mm。成品UTV子午线轮胎性能达到相关要
求，相对带束斜交轮胎，子午线轮胎外缘尺寸的稳定性和动平衡性能提高，原材料成本降低10. 76%。 |
| 英文摘要: |
| The development of the two stage building utility terrain vehicle （UTV） radial tire was
introduced. Based on the analysis of the configuration of sample tyres，28×10R14 UTV radial tire adopted
the structure of carcass ＋ belt ＋ capply，and its specific configuration was：carcass skeleton material
930dtex/2 nylon 66 cord，carcass crown angle 20°，belt skeleton material 930dtex/2 nylon 66 cord，
belt crown angle 65°，cap ply skeleton material 1400dtex/2 nylon 66 cord （one line winding with an
overlapping of 5 mm），steel ring Φ0. 96 mm steel wire with 5×4 arrangement，appex size（height×width）
35 mm×5 mm. The performance of the finished UTV radial tire met relevant requirements. Compared with
the belted bias tire，the peripheral dimension stability and dynamic balance performance of the UTV radial
tire was improved，and the raw materials cost was reduced by 10.76%. |
