摘　　要：介绍7.50-16LT 8PR加深花纹轻型载重斜交轮胎的设计。结构设计：外直径825 mm,断面宽191 mm,行驶面宽度163 mm,行驶面弧度高12 mm,胎圈着合直径406 mm,断面水平轴位置（H_1/H_2）0.806 0,胎面花纹深度15 mm,花纹饱和度58.1%,花纹周节数24。施工设计：胎面胶采用高耐磨配方,胎体采用4层2100dtex/2V_1锦纶6浸胶帘布,缓冲层采用1层1400dtex/2V_2锦纶6浸胶帘布,胎圈采用单钢丝圈结构,钢丝圈采用Φ0.96 mm的19~#镀青铜高强度回火胎圈钢丝。成型采用半自动压辊包边成型机,半芯轮式成型机头;硫化采用立式硫化罐。成品轮胎试验结果表明,轮胎充气外缘尺寸符合设计要求,物理性能和强度性能符合国家标准要求。The design on 7. 50-16 LT 8PR light truck bias tire with deepened pattern was described. In structure design,the following parameters were taken：overall diameter 825 mm,cross-section width 191 mm,width of running surface 163 mm,arc height of running surface 12 mm,bead diameter at rim seat406 mm,maximum width position of cross-section（H_1/H_2） 0. 806 0,pattern depth 15 mm,block/total ratio 58. 1%,and total number of pitches 24. In construction design,the following processes were taken：high wear resistant tread compound,4 layers of 2100dtex/2V_1 dipped nylon 6 cord for carcass ply,1 layer of 1400dtex/2V_2 dipped nylon 6 cord for breaker ply,and single bead wire ring for bead with Φ0. 96 mm 19~# high intensity plating bronze tempered bead wire. The tire was built on a semi-automatic building machine with half core wheel shape drum and cured using vertical autoclave. It was confirmed by the finished tire test that,the inflated peripheral dimension met the design requirements,and the physical properties and strength performance met the requirements of national standards.
