摘要
介绍12. 00-20 20PR工业车辆轮胎的设计。结构设计:外直径1 118 mm,断面宽278 mm,行驶面宽度250 mm,行驶面弧度高11 mm,胎圈着合直径508 mm,胎圈着合宽度216 mm,断面水平轴位置(H1/H2) 0.918 2,采用横向花纹,花纹深度22 mm,花纹饱和度78. 5%,花纹周节数36。施工设计:胎面采用三方四块结构,缓冲层采用2层1400dtex/2V3锦纶6浸胶帘布,胎体采用10层1400dtex/3锦纶6浸胶帘布(8V1+2V2),采用胶囊反包成型机成型、蒸锅式双模硫化机硫化。成品性能试验结果表明,轮胎的外缘尺寸、物理性能和耐久性能达到设计和相关标准要求。
The design on 12. 00-20 20 PR industrial vehicle tire was described. In the structure design,the following parameters were taken:overall diameter 1 118 mm,cross-sectional width 278 mm,width of running surface 250 mm,arc height of running surface 11 mm,bead diameter at rim seat 508 mm,bead width at rim seat 216 mm,maximum width position of cross–section(H1/H2) 0. 918 2,using transverse tread pattern,pattern depth 22 mm,block/total ratio 78. 5%,and number of pattern pitches 36. In the construction design,the following processes were taken:using three-formula and four-piece tread,2 layers of 1400dtex/2V3 dipped nylon 6 cord for breaker,10 layers of 1400dtex/3 dipped nylon 6 cord for carcass(8V1+ 2V2),using bladder turn-up building machine to build tire,and steamer type double mold curing press to cure tire.It was confirmed by the finished tire test that,the inflated peripheral dimension,physical properties and endurance met the requirements of design and relevant standards.
