摘要： A dual friction draft gear assembly for a car coupling system of a rail car includes a housing having an internal chamber. One or more friction shoes are disposed within the internal chamber. A first load block has, defines, or otherwise provides a first angled interface with the one or more friction shoes. A second load block has, defines or otherwise provides a second angled interface with the one or more friction shoes.

摘要： A labyrinth seal includes a seal case with an inner-diameter leg encircling a rotation axis, and an insert fixed in the seal case and encircling the rotation axis. The labyrinth seal also includes a slinger encircling the rotation axis and wrapping around the inner-diameter leg to cooperate with the seal case to form a first part of a labyrinth path. The slinger rotates relative to the seal case. The labyrinth seal also includes a rotor that encircles the rotation axis, cooperates with the insert to form a second part of the labyrinth path, and interlocks with the insert to limit axial movement of the rotor when the rotor rotates relative to the insert. The labyrinth seal may be combined with a bearing cone, a bearing cup, and a plurality of rollers to form a roller bearing assembly.

摘要： A leather flange for a bidirectional seal assembly includes a radial flange leg encircling a rotation axis of the leather flange. The leather flange also includes an oblique flange leg encircling the rotation axis and joined to the radial flange leg. The oblique flange leg extends both radially inward and axially away from the radial flange leg to form an oblique angle with the rotation axis. An end face of the oblique flange leg forms a sinusoidal pattern around a circumference of the leather flange. The end face also meets an air-side surface of the oblique flange leg to form a lip. When the leather flange is installed around a shaft, the lip forms a sinusoidal path around the circumference of the shaft. As the shaft rotates, the sinusoidal path of the lip creates an axial back-and-forth sweeping action.

摘要： A knuckle of a coupler of a rail vehicle includes a leading beam having a pulling face, a lateral offset beam extending from the leading beam, a tail extending from the lateral offset beam, an extension wall extending from the lateral offset beam towards an end of the tail, and a tapered lock engagement wall extending from the extension wall to the end of the tail. The tapered lock engagement wall is angled in relation to the extension wall. The tapered lock engagement wall is configured to engage an interior face of a main body of a lock of the coupler. The interior face defines a knuckle-engaging surface that is configured to bear against the tapered lock engagement wall.

摘要： A crash energy management system is configured to be disposed within a draft sill of a car coupling system for a rail vehicle. The crash energy management system includes a front sub-assembly including a front end plate, guide legs extending between the front end plate and a front central plate, a front central tube extending between the front end plate and the front central plate, and stop walls coupled to the guide legs. A rear sub-assembly is coupled to the front sub-assembly, and includes a rear end plate, a rear central plate, and a rear central tube extending between the rear end plate and the rear central plate.

摘要： Systems for monitoring brake systems on railway assets include a load measuring device. The load measuring device includes an instrumented coupling configured to be connected to the rigging of a brake system of the railway asset; and to an underframe of the railway asset. The load measuring device also includes a data collection unit configured to process an output of a sensor of the instrumented coupling and, based on the sensor output, determine the force being transmitted between the brake rigging and the underframe.

摘要： A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter and encircles the rotation axis, wherein, along the entire inner diameter of the shroud body, the inner diameter leg is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

摘要： A method for manufacturing a ring includes clamping a first region of a metal sheet against a mandrel, and, while the first region of the metal sheet is clamped against the mandrel, bending the metal sheet around the mandrel to join opposite end faces of the metal sheet and form the ring shaped to the mandrel. A system for manufacturing a ring from a metal sheet includes (a) a mandrel having a ring-shaped surface, (b) a clamp facing the ring-shaped surface and configured to clamp a first region of a metal sheet to the mandrel, and (c) a plurality of dies configured to bend the metal sheet around the mandrel, while the clamp clamps the first region to the mandrel, to join opposite end faces of the metal sheet and form a ring shaped to the ring-shaped surface.
