摘要
介绍275/30ZR20 97Y XL超高性能低断面轿车子午线轮胎的设计。结构设计:外直径668.4 mm,断面宽286 mm,行驶面宽度242 mm,行驶面弧度高11.8 mm,胎圈着合直径508.4 mm,胎圈着合宽度260 mm,断面水平轴位置(H1/H2)0.951,采用非对称花纹设计,花纹深度8.2 mm,花纹饱和度34.7%,花纹周节数34。施工设计:带束层采用2层1×3×0.30 HT OC钢丝帘布,冠带层采用930dtex/2改性锦纶66浸胶帘布,胎体采用1层2200dtex/2聚酯浸胶帘布,钢丝圈采用Φ1.3 mm回火钢丝,采用二次法成型、B型硫化机硫化。成品性能试验结果表明,成品轮胎外缘尺寸、强度性能、脱圈阻力、耐久性能和高速性能符合设计和相关标准要求。
The design of 275/30ZR20 ultra high performance low cross-section passenger car radial tire was described. In the structure design,the following parameters were taken:overall diameter 668.4 mm, cross-sectional width 286 mm, width of running surface 242 mm, arc height of running surface 11.8 ram, bead diameter at rim seat 504.8 mm, bead width at rim seat 260 mm, maximum width position of cross-section (Hj/H2) 0. 951, asymmetrical pattern design, pattern depth 8.2 mm, block/total ratio 34.7%, and total number of pitches 34. In the construction design, 2 layers of 1 × 3 × 0.30 HT OC steel cord for belt, 930dtex/2 dipped modified nylon 66 for cap ply, 1 layer of 2200dtex/2 dipped polyester cord for carcass ply, and 41.3 mm tempered bead wire for bead. The tire was built on two stage building machine and cured using a type B curing press. It was confirmed by the finished tire test that, the peripheral dimension, strength performance, bead unseating resistance, endurance performance and high speed performance met the requirements of the design and corresponding standards.
