0°带束层钢丝帘布对全钢载重子午线轮胎耐久性能的影响研究

Influence of 0°Belt Steel Cord on Durability of Truck and Bus Radial Tire

以315/80R22.5全钢载重子午线轮胎为例,研究0°带束层钢丝帘布的密度、宽度和强度对轮胎耐久性能的影响。结果表明:当0°带束层钢丝帘布的强度相同时,减小钢丝帘布密度、增大宽度有利于提高轮胎的耐久性能,并降低轮胎的成本;当0°带束层钢丝帘布宽度相同时,适当增大钢丝帘布的强度可以提高轮胎的耐久性能,但当钢丝帘布密度变大时,增大强度反而会影响轮胎的耐久性能,因此可以选择密度稍小的0°带束层钢丝帘布,既能保证轮胎的耐久性能,还可降低轮胎的成本。

Taking 315/80R22.5 truck and bus radial tire as an example,the influence of the density,width and strength of 0°belt steel cord on tire durability was studied.The results showed that when the strength of 0°belt steel cord was the same,reducing the density of the steel cord and increasing the width was beneficial to improve the durability and reduce the cost of the tire.When the width of 0°belt steel cord was the same,appropriately increasing the strength of the steel cord could improve the tire durability;however when the density of the steel cord became large,increasing the strength would affect the tire durability.Therefore,selection of the 0°belt steel cord with slightly smaller density could not only ensure the durability of the tire,but also reduce the cost of the tire.
