本文简要介绍美国GM公司电气动力部(EMD)新开发的一种适用于六轴机车的新型径向式转向架。这种转向架的主要优点是克服了在通过曲线时形成的轮对冲角,大大减轻轮轨磨耗,减少燃油消耗,改善走行品质,减少维修和延长大修间隔。 This article gives a brief introduction of a new radial bogie for the six-axle locomotive newly developed by the GM Department of Electrical Engineers (EMD). The major advantages of this bogie are overcoming the wheel angle of attack created when passing the curve, greatly reducing wheel and rail wear, reducing fuel consumption, improving ride quality, reducing maintenance and extending overhaul intervals.
