The flexible connection device of the invention is disposed between a flexible side beam of a bogey frame and an arm of an axle-box, and wherein the stiffness of the connection is greater in the vertical direction (Z) than in the two horizontal directions (X, Y). This enables the side beam to be decoupled from the axle-box, thereby reducing the stresses at the interfaces between these parts when the bogey frame moves transversely and vertically relative to the axles. This also presents the advantage of allowing relative displacements between the side beam and the axle-box.

A railway car truck includes side frames each having a pedestal formed on longitudinally opposite ends thereof. Each pedestal has an upper jaw and a lower jaw surrounding a pedestal opening. The upper jaw has a roof section above the pedestal opening and the lower jaw has an inner wall and an outer wall on opposite sides of the pedestal opening. The inner and outer walls are spaced apart from one another to define a wide pedestal opening. A bearing adapter is received in each pedestal opening. Each bearing adapter includes a concave opening to receive a bearing and a generally rectangular center section having a top surface generally opposite the concave opening. The bearing adapter has steps extending outward from sides thereof that have outer surfaces separated by a distance corresponding to the width of the pedestal opening. The railway car truck also includes an elastomeric adapter pad mounted on top of the bearing adapter that has a generally flat, generally rectangular top section and depending legs that extend along the outer surfaces of the steps. The top section defines a pad for engaging the roof section. The depending legs define pads for engaging the inner and outer walls.

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.

A railway car truck is provided that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of a bearing assembly. An adapter pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Protrusions extend from the adapter pad and are received in depressions in the bearing adapter to provide longitudinal stability for the adapter pad on the bearing adapter itself. Each adapter pad includes at least two wear tabs extending laterally outwardly from a top section of the adapter pad.

The moving pair junction part and the moving pair connecting part form an axial moving pair. The sliding part is of a cylindrical body. The outer side wall of the cylindrical body is in axial slidable connection with the axle box. The inner side wall of the cylindrical body is in axial fixed connection with the bearing mounting seat through the bearing. The wheel axial direction of the variable gauge bogie is adjustable to be adapted to different gauges, railway transportation of ''Silk Road Economic Belt'' is developed, and the problem that railway gauges are not uniform must be solved, therefore, it is very important and far-reaching to carry out design of the variable gauge bogie.

A resilient pad having a base with two side arms and two side lips for resiliently holding the base on a pedestal wear plate, the pad being configured with dome shaped portions disposed substantially perpendicular to the direction of the pad and being spaced apart from each other, where the pad, when installed with a pedestal wear plate serves to improve the force load handling and preferably re-distributes the load bearing surface from the edges and center of the adapter to the flat load bearing surface of the adapter, thus eliminating load on areas that have no support. Because the spring arms do not depend on bending of the base for their resiliency, the pad of the invention provides improved service stress capabilities and allows for longer life of the wear plate.

The invention discloses a rail engineering truck steering frame belonging to the field of rail vehicle steering frames. Aiming at the defects of large turning radius and incapability of meeting the low-speed operation working conditions of the traditional rail engineering truck, the steering frame comprises an H-type frame, ATP (Array Transform Processor) induction coil devices arranged at end parts of two lateral beams of the frame, rim lubricating devices arranged at two ends of a locomotive, a primary suspension device, a secondary suspension device, a third rail current collector arranged at the middles of the lateral beams of the frame, a basic brake device transversely arranged on the lateral beams of the frame, and a traction device connected with the frame by adopting a full-suspension manner; and a gear box is hung on a cross beam of the frame and is internally provided with two stages of gear transmissions with total transmission ratio of (7.63-10.03):1. The rail engineering truck steering frame has the highest operation speed of 90km/h, the continuous speed of about 18km/h and the lowest operation speed of below 5km/h and has the advantages of small turning radius, high low limit, simpler structure, convenience for maintenance and high reliability.

An apparatus and methods for identifying a defect and/or an operating characteristic of a system being monitored (and/or one or more of the system's components) are described. In an embodiment, orthogonally related data monitored by two or more detectors may be fused to determine whether a component of a system is defective and/or malfunctioning. Additionally or alternatively, data from a first detector may be determined to be accurate using non-orthogonally related data outputted by a second detector. Both types of determinations may be made with minimal or no false indications, which lowers the cost of operating the system being monitored. Embodiments of the invention may also be configured to forecast and/or prevent accidents and/or damage to the system being monitored by predicting whether a defect and/or a malfunction will occur
