摘要： A multi-unit articulated rail road cars has inter-body connections that include side bearings for the male and female ends of the car bodies to either side of a shared truck. The properties of those side bearings are different on the male side of the connection from on the female side of the connection. Those inter-body connections may be used in a multi-unit railroad car has an odd number of railcar units joined end to end by articulated connectors supported by railcar trucks. The railroad car has a transverse centerline. The arrangement of articulated connectors about the transverse centerline is symmetrical.

摘要： A railroad car truck includes a bolster mounted cross-wise between a pair of sideframes, with the sideframes supported on wheelsets. The bolster and the sideframes are steel castings. The interface between the sideframes and the wheelsets may include self-steering apparatus. Friction dampers are mounted at the interface between the bolster and the sideframes. The friction dampers have non-metallic friction surfaces that bear against the sideframe columns. The sideframes columns may be of a width for single dampers contact; double-damper side-by-side contact; or double-dampers separated by a land contact. The sideframe column bearing surfaces are permanent, and may be formed as part of the sideframe castings. The sideframes do not have removable, replaceable wear plates. Where double dampers are used, the damper edges may have both primary and secondary damper wedge angles.

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支架和一对侧框架，卡车摇枕横向安装在侧框架上。轴的端部和侧架座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抵抗跨越界面承载的重量的挠曲。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滑动性的倾向。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。

摘要： There is a damper wedge for a railroad car truck. It has a friction member that rides on the wear plate of the side frame column of the railroad car truck. It has a non-metallic wear surface; a spring seat that, in use, engages a spring of the railroad car truck; and an inclined damper wedge surface having a primary angle, alpha, and a secondary angle, beta. The spring seat has an axial centerline. The inclined damper wedge surface has a curvature. The curvature has a working point. The damper wedge has a datum plane that is normal to said non-metallic wear surface and that contains said axial centerline. The axial centerline meets said inclined damper wedge surface at an intersection point that is the center of a contact patch. The working point is located in a central region of the contact patch, or working surface patch.

摘要： There is a damper wedge for a railroad car truck. It has a removable and replaceable friction element that reciprocates on the wear plate of the side frame column of the railroad car truck. It has a non-metallic wear surface; a spring seat that, in use, engages a spring of the railroad car truck; and an inclined damper wedge surface having a primary angle, alpha, and a secondary angle, beta. The inclined damper wedge surface has a curvature. The curvature has a working point. The working point is located in a central region of a contact patch, or working surface patch. The nonmetallic wear surface material is mounted to a carrier that mounts removably to the damper wedge body. The carrier has fingers that span the wedge and that transfer shear and resist torsion, the fingers preventing the non-metallic member from migrating out of position.
