摘要
介绍7.50R16 14PR轻型载重子午线轮胎的设计和生产工艺。断面宽膨胀率取1.053,外直径膨胀率取1.006,水平轴位置(H1/H2)取1.14。胎体帘布采用1670dtex/2 DSP帘布,带束层采用3+9×0.22钢丝帘线,胎圈采用Φ0.96 mm回火钢丝,胎面采用二方三块机内复合方式。成品性能检测证明,轮胎充气外缘尺寸、强度、耐久性能和高速性能均符合设计要求。
The design and manufacturing technology of 7.50R16 14PR LTR tire are introduced. The following design parameters are taken, swelling ratio of cross-sectional width 1. 053, swelling ratio of overall diameter 1. 006, horizontal axial position （H1/H2） 1.14. 1670dtex/2 DSP cord is used for carcass ply,3q-gx0.22 steel cord is used for belt,t/X）. 96 tempered steel wire is used for bead and twoformula and three-piece tread assembled in extruder is used. It is confirmed by the test of finished tire that the inflated overall dimension, strength, endurance and speed performace are in accordance with the designed criteria.
