摘要
采用花纹夹缝的设计方法开发205/55R16 91Q冬季无内胎轿车子午线轮胎。结构设计:外直径630.2mm,断面宽226mm,行驶面宽度172mm,胎圈着合直径404.4mm,胎圈着合宽度190mm,胎面中间花纹筋设有短细纹沟槽,胎肩花纹位置设有长细纹沟槽,花纹沟槽壁全部配上锯齿状花纹沟,胎肩轮廓设计成棱角状,同时设置磨耗标示指示块和花纹磨损指示块。施工设计:采用2层胎面设计,胎面胶采用低硬度配方,基部胶采用低生热配方,采用二步法成型机成型、B型硫化机硫化。成品性能试验结果表明,成品轮胎的外缘尺寸、强度、脱圈阻力及高速、耐久和低气压性能均符合设计和相应标准要求,雪地制动、雪地操控和冰地制动性能良好。
The 205/55R16 91 Q winter tubeless passenger car tire was developed by using edge effect technique.In the structure design,the following parameters were taken：overall diameter 630.2mm,cross-sectional width 226 mm,width of running surface 172 mm,bead diameter at rim seat404.4mm,and bead width at rim seat 190 mm.Specifically,in the tread pattern design,short sipes were cut on the middle rib,long sipes were put in the shoulder pattern,grooves were serrated and angular shape was designed in shoulder profile.In addition,both tire wear mark and pattern wear mark were embedded in the tread.In the construction design,the following processes were taken：using dual tread layers,and soft crown compound and base compound with low heat build-up,and using two stage building machine to build tires and type-B curing press to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension,strength performance,bead unseating resistance,high speed performance,endurance performance and low inflation pressure performance met the requirements of relative design and standards,and the braking performance and driving performance on snowy or icy road conditions were good.
