The design on 215/70R17.5 14PR truck and bus radial tire was described.In the structure design,the following parameters were taken:overall diameter?770 mm,cross-sectional width?217 mm,width of running surface 175 mm,arc height of running surface 9.9 mm,bead diameter at rim seat?442.5 mm,bead width at rim seat?170 mm,maximum width position of cross–section(H1/H2)?1.1,self locking Z-Z siping tread pattern,variable pattern pitch,pattern depth?13.5 mm,block/total ratio?80%,and number of pattern pitches?61.In the construction design,the following processes were taken:co-extrusion of hot and cold feedings tread,4 layers belts structure,3×0.2+6×0.35HT steel cord for 1# belt,3×0.2+6×0.35HT steel cord for 2#和3# belt,5×0.30HI steel cord for 4# belt,3+9×0.22+0.15HT steel cord for carcass,using three-drum single-stage building machine to build tires,and double-mold B-style hot plate press to cure tires.It was confirmed by the finished tire test that,the inflated peripheral dimension,strength and endurance met the requirements of design,national standards and enterprise standards. |
