摘要： A railcar coupler may include a coupler head comprising a shank and a head portion, the head portion defining a cavity for receiving a knuckle, a thrower, and a lock. The cavity can include a top pulling lug, a bottom pulling lug, and a thrower retaining lug. The top pulling lug can be configured to engage an upper knuckle pulling lug, and the bottom pulling lug being can be configured to engage a lower knuckle pulling lug. During operation of the railcar coupler, the ratio of the stress between the top pulling lug and the bottom pulling lug can be configured to be better balanced to help extend the life of the railcar coupler assembly.

摘要： A knuckle may include a throat portion having a throat side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. The throat portion may also include a tail stop side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section.

摘要： A casting mold with rigging for casting a railcar coupler, which includes a shank portion and a head portion, includes cope and drag portions that define an external shape for each of at least two couplers. The couplers are nested together and oriented in opposite directions to one another along respective longitudinal axes. A down sprue is centered between the first and second couplers and is configured to direct molten material to a gating system positioned between the at least two couples.

摘要： A railroad coupler assembly having at least a body and a knuckle both formed in a no-bake manufacturing process, the body and the knuckle having dimensional tolerances of distances between features that wear during operation that are about half those obtained from a body and a knuckle manufactured by a green sand process, resulting in increased fatigue life compared to the body and the knuckle manufactured by a green sand process. The body and the knuckle resulting from the no-bake manufacturing process have no observable laps, scabs, chaplets or welding in critical areas of the body and knuckle, which are reflected in surface conditions matching SCRATA (Steel Castings Research and Trade Association) values of: D1 (laps); E1 (scabs); F1 (chaplets); and J1 (welds).
