摘要
介绍225/40ZR1892Y超高性能轿车子午线轮胎的设计。结构设计:外直径635 mm,断面宽236 mm,行驶面宽度198 mm,胎圈着合直径406.9 mm,零点半径272.95 mm,采用4条纵沟加横沟的单导向花纹设计,花纹深度8.1 mm,花纹饱和度68.9%,花纹周节数55。施工设计:胎面采用白炭黑胶料,冠带层使用2层1400dtex/2锦纶66浸胶帘布,带束层采用2+2×0.30HT钢丝帘线,胎体采用1层1670dtex/258E加密聚酯浸胶帘布,采用一次法成型机成型、液压硫化机硫化。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、耐久性能、高速性能和脱圈阻力均符合相应设计和国家标准要求。
The design on 225/40 ZR1892 Y ultra-high performance passenger car radial tire was described.In the structure design,the following parameters were taken:overall diameter 635 mm,crosssectional width 236 mm,width of running surface 198 mm,bead diameter at rim seat 406.9 mm,datum radius 272.95 mm,using the single direction pattern with 4 longitudinal groove and transverse groove design,pattern depth 8.1 mm,block/total ratio 68.9%,and number of pattern pitches 55.In the construction design,the following processes were taken:silica filled compound for tread,two layers of dipped 1400 dtex/2 nylon 66 cord for crown belt layer,2+2×0.30 HT steel cord for belt,1 layer of dipped 1670 dtex/258 E dense polyester cord for carcass,using one-step building machine to build tires,and hydraulic vulcanizing press to cure tires.The test results of finished tire showed that,the inflated peripheral dimension,strength,durability,high speed performance and the bead unseating resistance met the requirements of corresponding design and national standards.
