Abstract: A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.

Abstract: In one aspect of the present disclosure, a side bearing is provided for supporting a body of a rail car. The side bearing includes a base for being mounted to a truck of the rail car, a support configured to contact the body of the rail car and move along a vertical axis relative to the base with movement of the body, and at least one resilient foam member configured to deform with movement of the support. The side bearing further includes at least one friction damping member configured to be urged in a direction transverse to the vertical axis against the base by the support and resist movement of the support relative to the base.

Abstract: A vehicle truck includes a first side frame, a second side frame, a bolster, a first yaw separator connected to the first side frame, and a second yaw separator connected to the second side frame. Each yaw separator includes two steering arms and an arm connector assembly. The yaw separators are configured to alter yaw movement of the truck that leads to truck hunting.

Abstract: A bogie for a train vehicle includes two side frames, each side frame including two axle openings, each axle opening disposed on a corresponding end of the respective side frame, each side frame further forming a central slot disposed between the two axle openings; two wheelsets, each wheelset including an axle passing through two opposing axle openings between the two side frames; and a central beam having two ends, each end being slidably disposed within a corresponding central slot such that the central beam is disposed generally parallel to the axles of the two wheelsets and is slidable towards or away either of the two wheelsets.

Abstract: 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 behavior. 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.
Abstract translation: 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。

Abstract: A short wheelbase railroad truck having two axles intended to assume a radial configuration when the railroad vehicle rounds curves comprises a frame having two side members and axles mounted in bearing means. The bearing means are pivotally attached to the frame members with at least two of the bearing means being attached to the frame members by means of steering levers which are pivotally attached to the associated bearing means and the frame members for independent pivotal movement. Steering rods connect each steering lever to the vehicle body such that the chording of the vehicle as it rounds a curve will guide each axle to the radial alignment. In one embodiment each axle is guided by such steering rods and levers. In another embodiment one axle is guided by steering rods and levers and the side members move relatively longitudinally to guide the other axle.
