摘要： A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behaviour. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights.
摘要翻译： 铁路货车车辆有一个卡车垫子和一对侧架，卡车摇枕横向安装在侧框架上。 轴的端部与侧架之间的安装界面允许侧框架以摆动卡车的方式进行横向摇摆运动。 横向摆动与纵向自动转向能力相结合。 自动转向能力可以通过使用纵向取向的摇杆来获得，所述摇杆可以倾向于允许与穿过接口的承重成正比的挠曲阻力。 卡车可以具有安装在基座座中的辅助定心元件，并且那些辅助定心元件可以由弹性弹性体材料制成。 卡车也可能具有摩擦阻尼器，这些摩擦阻尼器具有不利于粘滑性能。 摩擦阻尼器可以在与侧架柱，倾斜面或两者配合的面上设有制动衬片或相似的特征。 摩擦阻尼器可以操作以产生不会过度不等的向上和向下的摩擦力。 摩擦阻尼器可以在卡车摇枕的每一端安装成四角配置。 弹簧组可以包括不同高度的弹簧的子组。
