摘要: The present railway car hatch cover latch assembly includes a latch plate. One end of the latch assembly rod is affixed to a bracket, with the adjustable end usually comprising an eye at the end of a threaded shaft. The threaded shaft is received in a keeper. The keeper in turn supports and holds a coil spring between the eye and the keeper cap. A bent hooking rod has two upturned ends that hold the end of the coil spring nearest the eye. The center of the bent hooking rod extends from the keeper to form a receiver. A latch plate includes a pivot rod that extends through the receiver of the bent hooking rod. The latch paddle itself contacts and holds the hatch cover is a compressively closed position against the railway car hatch ring.

摘要: A friction shoe includes a bottom base engaging and supported by a pair of support springs, and a sloped wall engaging the sloped support face of a bolster. The bottom base includes a cylindrical spring lug that has a center opening that extends through the spring lug. The bottom surface of the spring lug is flat and smooth and is configured to engage an additional concentrically nested support spring. The additional spring increases the force between the vertical support face of the wedge and the vertical wear plate of the side frame.

摘要: An elastomeric pad is provided for use in a railway car truck that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of an axle bearing assembly. An elastomeric pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Contact buttons extend from the top surface and bottom surface of the elastomeric pad and are received in openings in the elastomeric pad. A conductor provides an electrical connection between the contact buttons.

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 dead lever and a slack adjuster disposed proximate the first brake assembly, the slack adjuster connected to the first brake assembly and the dead 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 dead lever.

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 method of forming a mold for use in the casting of a steel railway freight car truck component is provided. A cope mold is formed by providing a near net shape oversize impression of a cope pattern of a product to be cast in a flask. A cope pattern of the product to be cast is then placed on the flask forming a spacing between the cope pattern and the oversize impression. A resin coated sand is then blown to form a sand layer between the oversized impression in the flask and the cope pattern. The resin sand is set to form a mold of a thickness between the oversized impression in the flask and the cope pattern of the product to be cast. The drag mold is formed in a similar manner.
