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 friction assist side bearing assembly for a truck assembly of a rail vehicle includes a first friction member, a second friction member that opposes the first friction member, and a cap coupled to the first friction member and the second friction member. The cap is configured to contact a portion of a car body coupled to the truck assembly.

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 supporting contact with each sideframe by a hinge assembly. The spring group is supported at each transom end. The hinge assembly includes a pin arrangement that allows one sideframe to move vertically with respect to the other sideframe.

摘要： A truck assembly for a rail vehicle includes at least one side frame including at least one lightener hole. At least one strain gage is disposed within the lightener hole(s). The strain gage(s) is configured to detect forces exerted into or onto the truck assembly. A method of detecting forces exerted into or onto a truck assembly of a rail vehicle includes disposing at least one strain gage within at least one lightener hole of at least one side frame of a truck assembly of the rail vehicle, and detecting the forces by the strain gage(s).

摘要： A force analysis system and method include a truck assembly that is configured to travel along a track having rails. The truck assembly includes a first side frame, a second side frame, a bolster extending between the first side frame and the second side frame, a first wheel set coupled to the first side frame and the second side frame, a second wheel set coupled to the first side frame and the second side frame, and one or more load cells disposed within the first side frame and/or the second side frame. The load cell(s) are configured to detect forces exerted in relation to the first side frame, the second side frame, and/or the bolster.

摘要： A three piece railway freight truck is comprised of two laterally spaced side frames between which a bolster extends. Suspension load springs support the bolster, and control springs support friction shoes. Both variations of friction shoes have gaps that will allow lateral movement of the friction shoes across the bolster or the friction shoes across the side frame. The lateral movement is accomplished by having a low friction material pad between the bolster and the friction shoe or a low friction material pad between the friction shoe and a wear plate that bears on the side frame. The low friction material with low siding resistance allows lateral displacement energy to be dissipated over the lateral decoupling clearance.

摘要： A stabilized railway car truck consists of two side frames and a holster. 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 has a pedestal opening at each end that receive a rotating lug to accept a elastomeric steering pad and bearing adapter. The attachment of the side frames and transom is a rigid pivotal connection. Friction shoes between the side frames and bolster provide damping of an initial low to a high rate friction once engaged. The pivotal decoupling of the side frame and transom, and the lateral movement of the friction shoes to the bolster, eliminates track displacement irregularities from reacting at the bolster and into the vehicle.
