宽体自卸车轮胎失效原因分析及其正确选型

Analysis of Failure Causes and Correct Selection of Tires for Wide Body Dumping Trucks

介绍宽体自卸车轮胎失效类型,分析轮胎的失效原因,并提出相应建议和轮胎正确选型方法。宽体自卸车轮胎因高负荷、高强度、使用环境复杂等特点导致胎面花纹利用率低,易早期失效,理赔率高。宽体车自卸车轮胎使用主要受到矿山开采类型、车型、载荷、运距、坡度、速度和气候等因素影响,结合使用场景合理选型是延长轮胎使用寿命、降低轮胎理赔率、提升矿山经济效益的重要途径。

The failure types of the tires for wide body dumping trucks were introduced,the failure causes of the tires were analyzed,and the corresponding suggestions and correct selection methods of the tires were proposed.Due to the characteristics of high load,high strength and complex usage environment,the tires for wide body dumping trucks had low utilization rates of tread patterns,making them prone to early failure and have high claims rates.The use of the tires for wide body dumping trucks was mainly influenced by factors such as mining types,vehicle types,loads,transportation distances,slopes,speeds and climates,and reasonable selections based on usage scenarios were important ways to extend tire service lives,reduce tire claim rates and improve economic benefits of mines.
