在一般人看来.车辆轮对似乎在过去150年的铁路历史上几乎没有什么变化。事实上,绝大多数的轮对仍然是根据史蒂文生原来的观点来制造的,即“两个轮子牢固地固定在车轴上,轮缘在内”。这个概念的有效性到现在仍无可非议,高速运行试验业已证明,在速度超过300公里/小时仍有其前途。 To the average person, wheel alignment seems to have changed little in the railway history of the past 150 years. In fact, the vast majority of wheelsets are still based on Steven Rawlings’s point of view that “the two wheels are firmly seated on the axle with the rim inside.” The validity of this concept is still beyond reproach, and high-speed tests have proven that it still has its future at speeds of over 300 km / h.
