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： A railroad car draft gear is provided which includes a housing. The housing is a unitary structure, having an open end and a closed end. Compressible spring elements are located inside the housing, with an end of the spring element located against the interior side of the closed end. A friction assembly is also located within the housing, near the open end. The friction assembly provides energy absorption during compression cycles. The spring element restores the friction assembly to its fully extended position after a compression event.

摘要： A cast steel railway wheel includes a hub that has an axial bore. A rim is concentric with the bore. A plate extends substantially radially from the hub to the rim. The plate has a front face and a rear face. The plate has a plurality of spokes that extend between the hub and the rim. Adjacent spokes have different thicknesses defined between the front face and the rear face.

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 shoe across 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 friction shoe or a low friction material pad between the friction shoe and wear plate that bears on the side frame. The low friction material 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.
