摘要： A process for producing a coupler and an improved coupler are provided. The process produces a coupler by constructing a mold that is a replica of the coupler and is constructed from a plurality of mold components that are selected and assembled to form a mold having the shape of the coupler. The mold components may include a front mold component section that forms the head of the coupler, a rear mold component section that forms the shank of the coupler, and, optionally one or more shelf components forming a shelf of the coupler. The front, rear and shank mold components may themselves be made from a plurality of mold components that are assembled together. The mold is formed from a consumable material, coating with a heat resistant material so that the assembled mold components are within a mold volume, and molten metal is added to the mold volume.

摘要： E-type and F-type yokes improve the ability of the yokes to be constructed having lighter weight yet function to handle loads from car coupling assembly components, such as, for example, a coupler mounted on the yoke. The E-type and F-type yokes have straps and openings provided in the straps, and are constructed from austempered ductile iron. Embodiments may be constructed with a tail or butt portion that includes sloped walls that form cavities in the butt portion of the yoke, where a supporting structure spans between the yoke rear wall and the draft gear seat wall.

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/in^3, which is approximately 8% less than steel, 0.283 lbs/in^3, 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.

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.
