Design on 13R22.518PR AEH2 Tubeless Mining Truck Radial Tire

介绍13R22.5 18PR AEH2矿山用全钢载重子午线轮胎的设计。结构设计:外直径1 137 mm,断面宽300 mm,行驶面宽度255 mm,行驶面弧度高9.5 mm,胎圈着合直径569.5 mm,胎圈着合宽度250 mm,断面水平轴位置(H_1/H_2)0.937,花纹深度24 mm,花纹周节数42,花纹饱和度52.5%。施工设计:胎面采用胎面胶+基部胶+过渡胶结构,1~#和2~#带束层采用3+8×0.33HT钢丝帘线,3~#带束层采用3×4×0.22HE钢丝帘线,0°带束层采用3×7×0.20HE钢丝帘线,胎体采用3+9+15×0.22+0.15钢丝帘线;采用一次法三鼓成型机成型、双模蒸锅式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、强度性能和耐久性能均达到国家标准要求。

The design on 13R22. 5 18PR AEH2 tubeless mining truck radial tire was described. In structure design, the following parameters were taken： overall diameter 1 137 mm, cross-sectional width 300 mm, width of running surface 255 mm, arc height of running surface 9.5 mm, bead diameter at rim seat 569.5 mm,bead width at rim seat 250 mm,maximum width position of cross-section （H1/H2） 0.937,pattern depth 24 mm,block/total ratio 52.5%,and number of pattern pitches 42. In construction design, the following processes were taken： 3 layer construction of tread compound, base compound and transition compound for tread, 3 ＋ 8 × 0.33HT steel cord for 1# and 2# belt, 3 × 4 × 0.22HE steel cord for 3# belt, 3 × 7 × 0.20HE steel cord for 0° belt, 3 ＋ 9 ＋ 15 × 0. 175 ＋ 0.15 steel cord for carcass ply, using three-drum building machine to build tire and double mold steamer B type curing press to cure tire. It was confirmed by the finished tire test that, the inflated peripheral dimension, strength and endurance reached the requirements of national standards.
