| 中文摘要: |
| 介绍225/60R18超低滚动阻力轿车子午线轮胎的设计。结构设计：外直径 727 mm，断面宽 233 mm，行驶面宽度 185 mm，行驶面弧度高 10.13 mm，胎圈着合直径 460.2 mm，胎圈着合宽度 177.8 mm，断面水平轴位置（H1/H2） 0.96，胎面采用4条纵沟宽度不等的非对称花纹、多段冠弧设计，花纹深度 6.7 mm，花纹饱和度 65%，花纹周节数 78。施工设计：胎面胶采用改性溶聚丁苯橡胶和改性白炭黑，采用1层冠带层和2层带束层设计，冠带层采用1400dtex/2锦纶66浸胶帘布，带束层采用3×0.28ST钢丝帘线，胎体采用2层1110dtex/2聚酯帘布。成品轮胎性能试验结果表明，轮胎的充气外缘尺寸、强度性能、脱圈阻力、高速性能和耐久性能均达到国家标准要求，滚动阻力系数为5.233 N·kN-1，通过噪声为70 dB（A），整车乘坐舒适性、操纵性能和制动性能等均优于竞品。 |
| 英文摘要: |
| The design on 225/60R18 passenger car radial tire with ultra low rolling resistance was introduced.In the structure design，the following parameters were taken：overall diameter 727 mm，cross-sectional width 233 mm，width of running surface 185 mm，arc height of running surface 10.13 mm，bead diameter at rim seat 460.2 mm，bead width at rim seat 177.8 mm，maximum width position of cross-section（H1/H2） 0.96，using asymmetric patterns with different widths of four longitudinal grooves and multi-section crown arc design for tread，pattern depth 6.7 mm，block/total ratio 65%，and number of pattern pitches 78.In the construction design，the following processes were taken：modified solution polymerized styrene butadiene rubber and modified silica for tread compound，using 1-layer cap ply and 2-layer belt design，1400dtex/2 nylon 66 dipped cord for cap ply，3×0.28ST steel cord for belt，two layers of 1110dtex/2 polyester cord for carcass.It was confirmed by the finished tire test that，the inflated peripheral dimention，strength performance，bead unseating resistance，high speed performance and endurance performance met the requirements of national standard，the rolling resistance coefficient was 5.233 N·kN-1，the passing noise was 70 dB（A），and the riding comfort，handling performance and braking performance of the whole vehicle were better than those of competing products. |
