摘要
介绍7. 00-15 12PR工业车辆轮胎的设计。结构设计:外直径744 mm,断面宽172 mm,行驶面宽度150mm,行驶面弧度高10mm,胎圈着合直径386mm,胎圈着合宽度140mm,断面水平轴位置(H_1/H_2) 0. 808,采用SD6000花纹,花纹深度14mm,花纹饱和度72%,花纹周节数28。施工设计:胎面采用三方四块结构,胎体采用4层高强度2100dtex/2V1和2层高强度2100dtex/2V2锦纶6浸胶帘布,缓冲层采用2层1400dtex/2锦纶6浸胶帘布,采用胶囊反包自动成型机成型,四立柱硫化机硫化。成品性能试验结果表明,成品轮胎充气外缘尺寸符合客户要求,物理性能符合国家标准要求。
The design on 7. 00-15 12 PR industrial vehicle tire was described.In the structure design,the following parameters were taken:overall diameter 744 mm,cross-sectional width 172 mm,width of running surface 150 mm,arc height of running surface 10 mm,bead diameter at rim seat 386 mm,bead width at rim seat 140 mm,maximum width position of cross–section(H_1/H_2) 0. 808,SD6000 tread pattern,pattern depth 14 mm,block/total ratio 72%,and number of pattern pitches 28. In the construction design,the following processes were taken:three-formula and four-piece structure for tread,4 layers of high strength 2100 dtex/2 V1 and 2 layers of high strength 2100 dtex/2 V2 dipped nylon 6 cord for carcass,2 layers of 1400 dtex/2 dipped nylon 6 cord for breaker ply;using automatic turn-up bladder building machine to build tire and four pillar curing press to cure tire. It was confirmed by the finished tire test that,the inflated peripheral dimension met the requirements of customers,and the physical properties met the requirements of the national standard.
