摘要： Systems and methods for railway asset management. The methods comprise: using a virtual reality device to recognize and collect real world information about railway assets located in a railyard; and using the real world information to (i) associate a railway asset to a data collection unit, (ii) provide an individual with an augmented reality experience associated with the railyard and/or (iii) facilitate automated railyard management tasks.

摘要： A truck assembly is configured to travel along a track having rails, and includes a first side frame, a second side frame, and a bolster extending between the first side frame and the second side frame. One or more of the first side frame, the second frame, or the bolster includes at least a portion formed as an I-beam that includes a web having a first end and a second end opposite from the first end, a first flange extending from the first end of the web, and a second flange extending from the second end of the web. A thickness of the web increases away from a first neutral axis towards the first flange and the second flange.

摘要： In accordance with one aspect of the present disclosure, a wear ring assembly is provided for a railway roller bearing. The wear ring assembly includes a wear ring having a central opening for receiving a journal of a railway wheel assembly and an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal. The spacers are spaced apart from each other about the wear ring. The insert may include one or more flanges that separate the wear ring from a bearing cone.

摘要： In one aspect, a mobile railway asset monitoring apparatus is provided that includes a sensor configured to produce a signal indicative of a rotation of a wheelset of a mobile railway asset. The apparatus further includes a processor to receive data corresponding to a ground speed of the mobile railway asset. The processor is operably coupled to the sensor, the processor configured to estimate a running dimension of the wheelset based at least in part on the rotation of the wheelset and the ground speed of the mobile railway asset. The processor is configured to determine at least one parameter of the mobile railway asset based at least in part on the running dimension of the wheelset.

摘要： 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.

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 wear liner installs into a bolster center bowl without the need for welding. The wear liner includes an annular wall forming an open-ring shape that defines a gap between two edges of the wall. The wear liner has one or more protrusions that extend outwardly from the annular wall. The protrusions are sized to engage with a corresponding recess in the center bowl. The wear liner is compressible by drawing the annular wall toward a closed-ring configuration so that the wear liner can be inserted into the center bowl while exerting an expansive, radially outward force. Upon expanding, and the protrusions engage with the recess or recesses in the peripheral wall of the center bowl. This engagement, along with the expansive pressure of the wear liner against the peripheral wall of the center bowl secures the wear liner in place.

摘要： A railway truck includes two parallel side frames, a suspension spring assembly supported by the side frames, and a bolster transversely mounted between the side frames and supported by the suspension spring assembly. Each side frame has at least one vertical support face, and the bolster has at least one sloped support face. A friction shoe includes a bottom base engaging and supported by a support spring, and a sloped wall engaging the sloped support face of the bolster. The friction shoe prevents bolster side wall wear.
