The design of 315/70R22.5 NHS 22PR all-steel off-the-road radial tire for small wheel excavator was introduced.In the structural design,the following parameters were taken:overall diameter 1 023 mm,cross-section width 315 mm,width of running surface 310 mm,arc height of running surface 9 mm,bead diameter at rim seat 570.5 mm,bead width at rim seat 247 mm,maximum width position of cross section(H1/H2) 0.87,using traction oriented pattern,pattern depth 21 mm,number of pattern pitches 27,and block/total ratio 45%.In the construction design,the following processes were taken:using 3+8×0.21ST steel cord for carcass,2 layers 3+8×0.33HT steel cords for belt,special high wear resistance compound for tread,using two-drum one-stage building machine to build tire and B type dual-mode curing press to cure tire.The test results of finished tire showed that the inflation peripheral dimension,physical properties and durability of the tire met the requirements of the corresponding design and national standards. |
