介绍21×8-914PR低滚动阻力工业车辆斜交轮胎的设计。结构设计:轮胎外直径512mm,断面宽199mm,行驶面弧度高5.5mm,行驶面宽度156mm,花纹采用条混花纹。施工设计:胎面采用一方一块设计,胎体采用4层1400dtex/3V1和2层1400dtex/3V2锦纶66帘布,缓冲层采用2层1400dtex/3V3锦纶66帘布,采用定制成型机和半芯轮式成型机头,胶囊硫化机硫化。成品性能试验结果表明,轮胎充气外缘尺寸和滚动阻力均符合标准及客户要求,且优于国外轮胎。
Describe the design of bias tire of 21 × 8-914PR low rolling resistance industrial vehicle. Structure design: The outer diameter of the tire is 512mm, the section is 199mm wide, the running surface is 5.5mm high, the width of the driving surface is 156mm, and the pattern is mixed with stripes. Construction design: The tread adopts one side design, the carcass adopts 4 layers of 1400dtex / 3V1 and 2 layers of 1400dtex / 3V2 nylon 66 plies, and the buffer layer adopts 2 layers of 1400dtex / 3V3 nylon 66 plies. It adopts custom molding machine and semi-core wheel molding Head, capsule curing machine curing. Finished product performance test results show that the tire inflatable rim size and rolling resistance are in line with standards and customer requirements, and better than foreign tires.
