Design on 205/55R16 All Season Passenger Car Radial Tire

介绍205/55R16 94V全天候轿车子午线轮胎的设计。结构设计:外直径628 mm,断面宽228 mm,行驶面宽度179 mm,行驶面弧度高7.9 mm,胎圈着合直径404 mm,胎圈着合宽度193 mm,断面水平轴位置(H_1/H_2)1.036,采用单导向花纹设计,花纹深度7.3 mm,花纹周节数69,花纹饱和度68.4%。施工设计:胎面由胎面胶、基部胶和胎肩翼胶组成,带束层采用2层3×0.3ST钢丝帘布,胎体采用1440dtex/2聚酯浸胶帘布;采用一次法成型机成型、液压硫化机硫化。成品性能试验结果表明,成品轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均符合设计和国家标准要求。

The design on 205/55 R16 94 V all season passenger car radial tire was described. In structure design,the following parameters were taken：overall diameter 628 mm,cross-sectional width 228 mm,width of running surface 179 mm,arc height of running surface 7. 9 mm,bead diameter at rim seat 404 mm,bead width at rim seat 193 mm,maximum width position of cross-section（H1/H2） 1. 036,directional pattern design for tire,pattern depth 7. 3 mm,total number of pitches 69,and block/total ratio 68. 4%. In construction design,the following processes were taken：3 compounds including tread consisted tread compound,tread slab base and shoulder wedge for tread,3×0. 3 ST steel cord for 1# and 2# belt ply,1440 dtex/2 polyester cord for carcass ply;and using one stage building machine to build tire and hydraulic curing press to cure tire. It was confirmed by the finished tire test that the inflated peripheral dimension,strength,endurance and high speed performance met the requirements of the design and national standards.
