介绍195/60R1588H轿车子午线轮胎的设计。结构设计：轮胎外直径614 mm，断面宽度212 mm，行驶面宽度160 mm，胎圈着合直径379 mm，胎圈着合宽度178 mm，断面水平轴位置(H1/H2)1.03，胎面采用4条纵向花纹主沟，花纹饱和度63.4%。施工设计：胎面采用三方四块结构，胎体采用1层1670dtex/2尺寸稳定型聚酯帘布，带束层采用2层2+2×0.25HT钢丝帘布和1层930dtex/2锦纶66帘布。采用二次法成型机成型，B型硫化机硫化。成品轮胎强度性能和脱圈阻力达到国家标准要求，耐久性能和高速性能达到企业标准要求。%The design of 195/60R15 88H passenger car radial tire is presented in this paper. In the structural design, the parameters are as follows: tire overall diameter 614 mm, cross sectional width 212 mm, width of running surface 160 mm, bead diameter at rim seat 379 mm, bead width at rim seat 178 mm, maximum width position of cross section﹙H1/H2) 1.03, 4 longitudinal main groove pattern, and pattern block ratio 63.4%. In the construction design, three formula and four piece tread is applied, one layer of 1670dtex/2 dimensionally stable polyester cord is used in carcass ply, and two layers of 2+2×0.25HT steel cord and one layer of 930dtex/2 nylon 66 cord are applied in the belt layer. The tire is built by using two stage tire building machine and cured on B-type vulcanizing machine. The experimental test results on the ifnished tire show that the strength performance of the tire and the bead unseating resistance meet the requirements of national standards, and the durability and high-speed performance meet the requirements of enterprise standards.
