摘　　要：介绍越野型265/65R18LT全钢轻型载重子午线轮胎的设计。结构设计:外直径809 mm,断面宽282 mm,行驶面宽度210 mm,行驶面弧度高11 mm,胎圈着合直径459 mm,胎圈着合宽度215.9 mm,断面水平轴位置(H_(1)/H_(2))0.9729,胎面采用越野花纹,并预留镶钉位置,花纹深度14 mm,花纹饱和度55%,花纹周节数40。施工设计:胎面采用胎冠胶和基部胶2层设计,1^(#)和2^(#)带束层采用3×0.20+6×0.35HT钢丝帘线,冠带层采用930dtex/2锦纶66浸胶帘布,胎体采用3+9×0.22+0.15钢丝帘线。成品性能试验结果表明,轮胎的充气外缘尺寸和各项性能均符合国家标准要求。轮胎接地印痕矩形率为1.01,肩部沉降为1.05,与有限元分析结果一致。The design of 265/65R18LT all-steel light truck and bus radial tire for off-road was introduced.In the structural design,the following parameters were taken:overall diameter 809 mm,crosssection width 282 mm,width of running surface 210 mm,arc height of running surface 11 mm,bead diameter at rim 459 mm,bead width at rim 215.9 mm,maximum width position of cross-section(H_(1)/H_(2))0.9729,off-road pattern for tread with reserved nail positions,pattern depth 14 mm,block/total ratio 55%,and number of pattern pitches 40.In the construction design,the following processes were taken:2-layer design of crown compound and base compound for tread,3×0.20+6×0.35HT steel cord for 1^(#)and 2^(#)belt,930dtex/2 nylon 66 dipped cord for cap ply,3+9×0.22+0.15 steel cord for carcass.The performance test results of the finished product indicated that the inflated peripheral dimension and various properties of the tire met the requirements of national standards.The rectangular ratio of tire foot print was 1.01,and the shoulder settlement was 1.05,which was consistent with the finite element analysis results.
