摘要： A knuckle pin, coupling system, and method for producing a knuckle pin are provided, the knuckle pin having a cylindrical body with a longitudinal slot therein separating vertical edges of the cylindrical body, with one or more first retaining elements that span outward of the cylindrical body, and a second retainer that includes one or more of opposing apertures, and bendable legs. A method for producing the knuckle pin is provided, where a blank is stamped into a workpiece that corresponds to the pin to be produced, and the stamped workpiece is rolled to produce the pin with the slot.

摘要： The sideframe and bolster of a railway car truck are constructed such that basic overall sideframe and bolster appearance is maintained, but the actual material it is constructed of is changed. The material used is changed from cast steel to an austempered metal, such as, cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over ( )}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over ( )}3. This immediately allows for a reduction in weight. A second benefit is that iron is easier to pour than steel and actually increases in volume, slightly, as metal cools compared to steel which shrinks. Efficient use of materials is improved, meaning less metal is used to make the same final shape, as a way of reducing the sideframe and bolster weight. Both factures combined allow for a lighter weight railway car truck, sideframe and bolster, while utilizing standard designs.

摘要： A process for producing a coupler knuckle and an improved coupler knuckle design are provided. The process produces a coupler knuckle by constructing a mold having the shape of the coupler knuckle. The mold is coated with a material that is resistant to melting at the molten melt temperatures of the molten metal used to form the knuckle. With the mold coated, the cavities in the mold interior are filled by placing an inert material therein. The molten metal used for forming the knuckle contacts the mold and consumes it, while the coating serves to provide a shape for the knuckle.

摘要： A wear plate for use with a railway truck, the wear plate being configured for installation on a downwardly facing surface of a pedestal opening of a side frame of a railway truck. The wear plate includes a base and a pair of side walls extending upwardly from opposite sides of the base with inwardly disposed locking features designed to engage the pedestal when the wear plate is installed, the locking features in a preferred embodiment being configured as resilient projections that engage, clamp or drag lock onto opposite sides of the pedestal with the base of the wear plate protecting the downwardly facing pedestal surface. The wear plate may be constructed from malleable or ductile metals or plastics.
