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： A friction shoe is provided for use in a railway truck. The friction shoe is placed such that it frictionally engages both a wear plate on the side frame vertical column and wear plates on the slope surfaces of the bolster to dampen the oscillating motion of the bolster when supported by spring groups in the side frame. The shoe is provided with sloped surfaces that engage complementary slope surfaces on the bolster. Wear plates are fitted and held on the sloped surfaces of the bolster and on the vertical columns of the side frames.

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： A system, method and assembly for detecting the operational status of one or more discharge gates on one or more railcars. The system and method monitor parameters that include whether the discharge gate is open or closed, whether the railcar is in motion or not, and whether the railcar is in a location where it is acceptable for the discharge gate to be open. Sensors carry out the monitoring, and the information obtained by monitoring the parameters are used to determine if a notification event has taken place and if so, a notification of such event can be transmitted to a remote receiver. A change in the status of any one of the monitored parameters can trigger the determination of whether a notification event has occurred.

摘要： Braking systems for railway cars are provided. A braking system defines a longitudinal axis, and includes a first brake assembly, a second brake assembly, and an actuator operable to generate a linear force, the actuator disposed proximate the second brake assembly. The braking system further includes a movable rod and a fixed rod extending between the first brake assembly and the second brake assembly. In some embodiments, the braking system further includes a lever and a slack adjuster disposed proximate the first brake assembly, the slack adjuster connected to the first brake assembly and the lever and operable to adjust a distance along the longitudinal axis between a reference point of the first brake assembly and a pivot point of the lever. In some embodiments, the braking system includes a strut connected to the second brake assembly, the actuator, fixed rod and movable rod connected to the strut.

摘要： A stabilized railway car truck consists of two side frames and a bolster. The bolster has laterally opposite ends, each end extending into and supported within a side frame opening on a spring group. The stabilized railway car truck also includes a transom extending into, and supported within, a side frame opening. The spring group is supported at each transom end. Each side frame includes an integrally cast transom bearing over which a transom support bearing is fitted. The pivotal decoupling of the side frame and transom eliminates track displacement irregularities from reacting at the bolster and into the vehicle.
