有内胎全钢载重子午线轮胎无内胎化应用研究

Research on Tubeless Application of Truck and Bus Radial Tire with Inner Tube

研究有内胎全钢载重子午线轮胎的无内胎化应用。以10. 00R20,11. 00R20和12. 00R20规格全钢载重子午线轮胎为例,通过改善轮胎内部气密性和胎圈圈口部位材料分布,装配分体式无内胎轮辋,使有内胎轮胎与轮辋和挡圈紧密配合,不用内胎和垫带就能使有内胎轮胎具有良好的气密性。

The tubeless application of truck and bus radial tire with inner tubes was studied.Taking 10.00R20,11.00R20 and 12.00R20 truck and bus radial tires as examples,by improving the internal air tightness of the tire and the material distribution of the bead mouth,using split tubeless rim,and fitting the rim and retaining ring tightly,the tires which usually had inner tuber could possess good air tightness without the inner tube and pad.
