摘　　要：介绍355/65—15 24PR TL E-3低断面无内胎重型动力平板运输车轮胎的设计情况。结构设计:外直径806mm,断面宽度362 mm,行驶面宽度328 mm,行驶面弧度高4.6 mm,胎圈着合直径385.5 mm,胎圈着合宽度247.5 mm,断面水平轴位置(H_1/H_2)1.333,采用高通过性块状花纹,花纹深度22.5 mm,花纹周节数24。施工设计:胎面采用三方五块结构,胎体和缓冲层分别采用12层1400dtex/3和2层930dtex/2V_3锦纶66帘布,胎圈采用双钢丝圈结构;轮胎成型采用指形正包、胶囊反包成型机,硫化采用双模硫化机。成品轮胎充气外缘尺寸和物理性能满足设计和国家标准要求,实际使用性能良好。This paper introduces the design of 355/65—15 24 PR TL E-3 low profile tubeless heavy duty flatbed truck tire. In the structure design,the following parameters were taken：outer diameter 806 mm,cross-section width 362 mm,width of running surface 328 mm,arc height of running surface 4. 6 mm,bead diameter at rim seat 385. 5 mm,bead width at rim seat 247. 5 mm,maximum width position of cross-section（H1/H2） 1.333,high through block pattern,pattern depth 22. 5 mm,and number of pattern pitches 24. In the construction design,three formulation and five piece structure was used for tread,12 layers of 1400dtex/3 and 2 layer of 930dtex/2V3 nylon 66 cords were applied in the carcass ply and breaker ply,respectively,and double steel ring structure was adopted in bead. The tire was formed on finger-shaped turn-up building machine and cured on press curing machine. The test results showed that the inflated peripheral dimensions and physical properties of the finished tires met the requirements of the design and national standards,and the finished tires showed good performance in practical use.
