摘要: A system and method for detecting the operational status of a brake system on a railcar. The system receives from a sensor an indication of the magnitude of a braking force applied by the braking system in response to an instruction to increase or decrease the braking force. It compares the response to possible responses of the braking system in view of the instruction provided. Based on the comparison, the system generates at least one of a message and/or an alert indicating the status of the brake system. Additional sensors, including a pressure sensor on a brake pipe of the railcar, can be added for additional functionality.

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.

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. The insert may be easily installed in the opening of the wear ring and separate the wear ring from the journal and the bearing cone to reduce fretting wear between the components.

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.
