| 介绍了285/70R19.5全钢载重子午线轮胎的设计,结构设计：外直径 892mm,轮胎断面宽 282mm,行驶面宽度 224mm,行驶面弧度高 8mm,胎圈着合直径 493.5mm,胎圈着合宽度222mm,断面水平轴位置(H1/H2) 1.028,花纹深度13.5mm,花纹饱和度 76.4%,采用条形花纹设计。施工设计：胎面采用两方两块设计,胎体采用3 9*0.22 0.15钢丝帘线,1#、2#带束层采用3*0.20 6*0.35HT高强度钢丝帘线, 3#带束层采用5*0.30HI高抗冲击帘线,0°带束层采用3×7×0.20HE高伸长钢丝帘线；成型采用一次法胶囊三鼓成型机,硫化采用65英寸热板充氮双模硫化机进行硫化。成品性能试验结果表明,成品轮胎的外缘尺寸、强度性能、耐久性能均达到国家标准要求。 |
| 英文摘要: |
| The design of 285/70R19.5 truck and bus radial tire was described. In structure design, the following parameters were taken: overall diameter 892mm, cross-sectional width 282mm, width of running surface 224mm, height of running surface 8mm, bead diameter at rim seat 493.5mm, bead width at rim seat 222mm, maximum width position of cross section (H1/H2) 1.028, pattern depth 13.5mm, block/groove ratio 76.4%, with the design of 5 rib tread pattern. In the construction design, the following processes were taken: two-formula and two-piece extruded tread. 3 9*0.22 0.15 steel cord for carcass ply, 3*0.20 6*0.35HT steel cord for 1# and 2# belt ply, 5*0.30HI steel cord for 3# belt ply, 3×7×0.20HE steel cord for 0°belt ply; using single stage tree-drum building tires, and using 65 heat board vulcanizer to cure tires. It was confirmed by the tests of tires that the inflated peripheral dimension, strength performance and endurance met the requirements in the relative design and national standard. |
