从轮轨接触的形式、轮轨磨损成因及降低轮轨磨耗的对策分析出发,通过对独立旋转车轮工矿车辆转向架的研制和运行验证后,对该转向架的优点做了总结,结果表明该转向架在降低轮轨磨耗、提高曲线通过能力、提高适应线路扭曲的能力、改善车辆运行品质等方面均有明显效果,这对铁路干线车辆转向架具有借鉴意义。 Starting from the contact between wheel and rail, the causes of wheel and rail wear and the countermeasures to reduce the wear of wheel and rail, the advantages of the bogie are summarized after the development and operation of bogie of independent rotating wheel industrial and mining vehicles. The bogie has obvious effect in reducing the wheel and rail abrasion, improving the curve passing ability, improving the ability of adapting the line twisting and improving the running quality of the vehicle, which is of reference significance to the railway truck bogie.
