我国轮轨表面磨耗损伤情况是严重的,每年为此要消耗大量的材料、人工和能源,而且降低了机车车辆和线路设施的利用效率。理论研究和大量的现车试验表明,采用磨耗型车轮踏面和磨耗型铜轨以改善轮轨接触形式,在轮轨之间涂油润滑以改善轮轨接触条件,都收到了减少轮轨磨耗的明显效果,应予大力推广。 China’s wheel and rail surface wear damage is serious, each year to consume a large amount of materials, labor and energy, but also reduces the locomotive and rolling stock facilities and utilization efficiency. Theoretical studies and a large number of current vehicle tests have shown that the use of wear-type wheel treads and wear-type copper rail to improve wheel-rail contact form, lubricated between wheel and rail to improve wheel-rail contact conditions, have received less wheel and rail wear Obvious effect, should be vigorously promoted.
