摘　　要：介绍255/50R19107T镶钉雪地轮胎的设计。结构设计:外直径735 mm,断面宽296 mm,行驶面宽度215mm,行驶面弧度高9.7mm,胎圈着合直径486.6mm,胎圈着合宽度229mm,花纹深度9.5mm,花纹饱和度66%,花纹周节数69。施工设计:胎面采用四复合结构,带束层采用2层2+2×0.25HT钢丝帘线,2层0°冠带层采用锦纶帘线,胎体采用2层1100dtex/2DSP聚酯帘布,钢丝圈采用Φ1.5 mm高强度胎圈钢丝,钢丝圈直径为493.6 mm;采用一次法成型机成型、AB型胶囊硫化机硫化。成品性能试验结果表明,成品轮胎的外缘尺寸、强度性能、脱圈阻力、耐久性能和高速性能均达到相应设计和国家标准要求。成品轮胎通过室外实车测试,具有较好的舒适性、干湿地性能和冰雪地性能。The design on 255/50R19107T studded snow tire was described.In the structure design,the following parameters were taken:overall diameter 735 mm,cross-sectional width 296 mm,width of running surface 215 mm,arc height of running surface 9.7 mm,bead diameter at rim seat 486.6 mm,bead width at rim seat 229 mm,pattern depth 9.5 mm,block/total ratio 66%,and number of pattern pitch 69.In the construction design,the following parameters were taken:co-extruded tread with four compounds,2 layers of 2+2×0.25HT steel cord for belt,2 layers of nylon cord for 0°crown ply,and 2 layers of 1100dtex/2DSP polyester cord for carcass,Φ1.5 mm high-strength bead steel wire for the bead ring with a diameter of 493.6 mm,using one-stage building machine to build tires and AB-bladder curing press to cure tires.The test results of the finished tire showed that the inflated peripheral dimension,strength,bead unseating resistance,endurance and high speed performance met the requirements of relative design and national standards.The finished tire passed outdoor vehicle testing,had good comfort,possessed excellent wet and dry performance,and had good ice and snow performance.
