Design on 35×12.50R22LT 117Q 10PR Mudrock Pattern Tire

介绍35×12.50R22LT 117Q 10PR泥石花纹轮胎的设计。结构设计:外直径877 mm,断面宽322 mm,行驶面宽度258.3 mm,行驶面弧度高10.282 mm,胎圈着合直径559.2 mm,胎圈着合宽度287.02 mm,断面水平轴位置(H1/H2)0.951,采用对称花纹设计,花纹深度16 mm,花纹饱和度51.8%,花纹周节数40。施工设计:带束层采用3×0.2+6×0.35HT钢丝帘布,胎体采用1440dtex/2-104聚酯帘布,钢丝圈采用Φ1.295 mm回火钢丝;采用二次法成型机成型,液压硫化机硫化。成品性能试验结果表明,成品轮胎的外缘尺寸、强度性能、耐久性能及高速性能均符合相关标准和设计要求。

The design on 35×12.50 R22 LT 117 Q 10 PR mudrock pattern tire was described. In structure design,the following parameters were taken：overall diameter 877 mm,cross-sectional width 322 mm,width of running surface 258. 3 mm,arc height of running surface 10. 282 mm,bead diameter at rim seat 559. 2 mm,bead width at rim seat 287. 02 mm,maximum width position of cross-section（H1/H2） 0. 951,symmetrical pattern design for tire,pattern depth 16 mm,block/total ratio 51. 8%,and total number of pattern pitches 40. In construction design,the following processes were taken：3×0. 2 ＋6×0. 35 HT steel cord for belt,1440 dtex/2-104 polyester cord for carcass ply,Φ1. 295 mm tempered wire for bead;and using two stage building machine to build tire and hydraulic vulcanization machine 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 relative standards and design.
