摘　　要：介绍325/95R24(12.00R24)TT/TL通用型全钢载重子午线轮胎的设计。结构设计:外直径1228 mm,断面宽312 mm,行驶面宽度240 mm,行驶面弧度高7.47 mm,胎圈着合直径612.6 mm,胎圈着合宽度216 mm,断面水平轴位置(H_(1)/H_(2))1.15,胎面采用以横沟为主的横纵混合花纹沟、大块状花纹,花纹深度20.5 mm,花纹饱和度66%,花纹周节数49。胎侧字体排布考虑到共用问题,同时打刻325/95R24和12.00R24。施工设计:胎面采用两方三块翼胶结构,1^(#)和2^(#)带束层采用3+8×0.33HT钢丝帘线,3^(#)带束层采用5×0.30HI钢丝帘线,0°带束层采用3×7×0.20HE钢丝帘线,胎体采用0.22+6+11×0.205ST超高强度钢丝帘线。采用一次法成型机成型,蒸锅式硫化机硫化。成品轮胎性能试验结果表明,轮胎的充气外缘尺寸、强度性能和耐久性能均满足相应设计和国家标准要求。The design on 325/95R24(12.00R24)TT/TL general truck and bus radial tire was introduced.In the structure design,the following parameters were taken:overall diameter 1228 mm,crosssection width 312 mm,width of running surface 240 mm,arc height of running surface 7.47 mm,bead diameter at rim 612.6 mm,bead width at rim seat 216 mm,maximum width position of cross-section(H_(1)/H_(2))1.15,mixed horizontal and longitudinal pattern groove and large block pattern for tread with main horizontal groove,pattern depth 20.5 mm,block/total ratio 66%,and number of pattern pitches 49.In the sidewall trademark font design,“325/95R24”and“12.00R24”were engraved on the sidewall at the same time to ensure the consistency of the font layout.In the construction design,the following processes were taken:two-formula and three-piece structure for tread with wing shape,3+8×0.33HT steel cord for 1^(#)and 2^(#)belt,5×0.30HI steel cord for 3^(#)belt,3×7×0.20HE steel cord for 0°belt,0.22+6+11×0.205ST steel cord for carcass,using one stage building machine to build tire and steam press to cure tire.It was confirmed by the tests of the finished tire that,the inflated peripheral dimension,strength and endurance met the requirements of corresponding design and national standards.
