介绍LT245/75R16 120/116S10PR全路况越野子午线轮胎的设计。结构设计:外直径771mm,断面宽256mm,行驶面宽度192mm,行驶面弧度高10.2mm,胎圈着合直径404.6mm,胎圈着合宽度209.6mm,断面水平轴位置(H1/H2)1.0,采用无向大花纹块设计,花纹深度13mm,花纹饱和度64%,花纹周节数32。施工设计:胎面采用三方四块结构,胎体采用2层2200dtex/3聚酯浸胶帘布,带束层采用2层开放型2+7×0.26HT钢丝帘布;采用两次法成型机成型,双模热板式B型硫化机硫化。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满足相应设计和标准要求。
Describe the design of LT245 / 75R16 120 / 116S10PR all-terrain off-road radial tire. Structure design: outer diameter of 771mm, section width of 256mm, the width of 192km, the driving surface of the arc high 10.2mm, the bead cohesion diameter of 404.6mm, bead width of 209.6mm, section horizontal axis position (H1 / H2) 1.0, Untagged large block design, pattern depth 13mm, 64% pattern saturation, the number of weeks pattern 32. Construction design: tread with three square four structure, the carcass with 2 layers of 2200dtex / 3 polyester dipped cord, the belt layer with 2 open 7 +2 0.26HT steel cord; using two law forming machine molding, Dual-mode hot plate B-type curing machine curing. Finished product performance test results show that the finished tire inflatable rim size, strength performance, durability and high-speed performance meet the corresponding design and standard requirements.
