摘要
介绍14.00R20 20PR全钢载重子午线轮胎的设计。结构设计:外直径1 245mm,断面宽372mm,行驶面宽度295mm,行驶面弧度高9.608mm,胎圈着合直径511mm,胎圈着合宽度267mm,断面水平轴位置(H1/H2)0.897,花纹深度25mm,花纹饱和度72.35%,采用横向块状花纹设计。施工设计:胎面采用两方两块结构;胎体采用3+9+15×0.245HT钢丝帘线,1#和2#带束层采用3+9+15×0.22+0.15钢丝帘线,3#带束层采用5×0.35HI钢丝帘线,0°带束层采用3×7×0.20HE钢丝帘线;采用一次法成型机成型,蒸锅式双模硫化机硫化。成品轮胎试验结果表明,轮胎充气外缘尺寸、强度性能和耐久性能均符合相应设计和国家标准要求。
The design of 14.00R20 20PR truck and bus radial tire was described. In the structure design,the following parameters were taken：overall diameter 1 245 mm,cross-sectional width 372 ram,width of running surface 295 ram,height of running surface 9. 608 ram,bead diameter at rim seat 511 mm,bead width at rim seat 267 ram,maximum width position of cross section （H1/H2） 0. 897, pattern depth 25 ram, block/groove ratio 72. 35%, with the design of transverse pattern groove. In the construction design, the following processes were taken： two-formula and two-piece extruded tread,3＋9＋15×0. 245HT steel cord for carcass ply,3＋9＋15 ×0.22＋0.15 steel cord for 1# and 2# belt ply,5X0. 35HI steel cord for 3# belt ply,3×7×0.20HE steel cord for 0° belt ply;using single stage building machine to build tires, and using double mold steam vulcanizer to cure tires. It was confirmed by the tests of finished tires that the inflated peripheral dimension, strength performance and endurance performance met the requirements in the relative design and national standard.
