摘要： The coupler system of a railway car truck is constructed such that basic overall appearance may be maintained, but the actual material of which it is constructed is changed. According to one embodiment, the coupler is constructed from 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, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal coupler and components thereof. A second benefit of embodiments of the present invention provides for a more efficient use of materials, meaning less metal is used to make the same final shape, as a way of reducing the coupler weight. Both factures combined allow for a lighter weight coupler, while utilizing the standard designs. Alternate coupler configurations are disclosed for further reducing coupler weight.

摘要： A railcar end unit is operable to be mounted in a center sill between buff and draft sill stops. The buff and draft end bodies are configured to be shiftably mounted relative to the center sill to engage the respective sill stops and to shift axially relative to one another along a unit axis. The end unit includes a buff spring pack operably mounted between the end bodies and compressible along the unit axis from a neutral condition to a compressed condition.

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 railcar coupler includes a coupler head portion extending from a shank portion. The coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler head portion comprises a nose portion and a gathering face extending from the nose portion for engaging a second coupler knuckle coupled to the second railcar coupler. The coupler head portion comprises a guard arm portion extending from the nose portion towards the shank portion. The coupler head portion comprises a horn portion having a back surface. A distance between the back surface of the horn portion and a nose end of the guard arm portion is less than 11 inches. The coupler head portion comprises a locklifter shelf less than 2 inches above a bottom edge of the coupler.

摘要： Lightweight yokes are provided. According to some embodiments, the basic overall appearance of the yoke may be maintained, but the actual material of which it is constructed is changed. According to other embodiments, the yoke is provided with an improved lightweight construction, and, yet other embodiments the yoke may be provided with an improved construction and formed from a preferred material. Yokes may be constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in̂3, which is approximately 8% less than steel, 0.283 lbs/in̂3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal yoke. Yokes have improved configurations which may require less metal to produce the yoke. Both, the lightweight material and improvements in configuration of the yoke structure may combine to provide a lighter weight yoke.
