摘要
介绍12R22.5节油型轮胎的设计。结构设计:外直径1080 mm,断面宽300 mm,行驶面宽度235 mm,行驶面弧度高8.3 mm,胎圈着合直径570.5 mm,胎圈着合宽度241.3 mm,断面水平轴位置(H_(1)/H_(2))1.2,胎面花纹采用等节距设计,花纹周节数61,花纹深度15 mm,花纹饱和度80%。施工设计:胎面采用低滚动阻力配方,热喂料、冷喂料双复合挤出,胎体采用3×0.24/9×0.225CCST钢丝帘线,1^(#),2^(#),3^(#)带束层采用3×0.20+6×0.35HT钢丝帘线,4^(#)带束层采用5×0.35HI钢丝帘线。成品轮胎性能试验结果表明,12R22.5节油型轮胎的充气外缘尺寸、强度和耐久性能达到国家标准要求,滚动阻力级别达到B级,与普通轮胎相比可使车辆油耗降低5%以上。
The design on 12R22.5 fuel saving tire was described.In the structure design,the following parameters were taken:overall diameter 1080 mm,cross-sectional width 300 mm,width of running surface 235 mm,arc height of running surface 8.3 mm,bead diameter at rim seat 570.5 mm,bead width at rim seat 241.3 mm,maximum width position of cross–section(H_(1)/H_(2))1.2,equal pitch design for the tread pattern,number of pattern pitches 61,pattern depth 15 mm,and block/total ratio 80%.In the construction design,the following processes were taken:co-extruded tread with hot feed and cold feed using the compounds having low rolling resistance,3×0.24/9×0.225CCST steel cord for carcass,3×0.20+6×0.35HT steel cord for 1^(#),2^(#)and 3^(#)belt,and 5×0.35HI steel cord for 4^(#)belt.It was confirmed by the finished tire test that,the inflation peripheral dimensions,strength performance and durability of the 12R22.5 fuel saving tire met the requirements of national standards,and the rolling resistance level reached Level B,which could reduce the vehicle fuel consumption by more than 5%compared with ordinary tires.
