Abstract: Freight truck castings on freight trucks have an interface between the freight car truck sideframe and a bearing assembly or bearing adapter. The present invention includes a sideframe with a pedestal jaw, placing a bearing assembly inside the pedestal jaw, and forming a pedestal roof in the pedestal jaw in a shape to evenly distribute a load between the pedestal roof and the bearing assembly. The present invention also provides for reducing load concentration on an interface between a pedestal roof and an axle. The present invention provides a sideframe with two pedestal roofs disposed at opposite ends of the sideframe, an axle placed under the pedestal roof, and an angled interface. The angled interface is formed between the pedestal roof and bearing adapter to reduce load concentration.

Abstract: A transition member for use in a railway freight car is provided. The transition member provides connection between the dissimilar cross sections of the underbody and draft sill of the railway freight car and the center sill of the railway freight car. The transition member is usually a unitary cast steel structure and is of a generally rectangular or square cross section.

Abstract: An improved sideframe has a bolster opening configured to accept a variety of spring group and friction shoe assembly designs. The bolster opening is defined by a bottom section, a top compression member, and two opposing column members and has two column wear plates each secured to the opposing column members. The bottom section of the bolster opening defines a spring seat. The dimensions of the bolster opening of the sideframe allow for a variety of freight car truck suspension systems including the spring group, bolster and friction shoe used therewith.

Abstract: An improved three-piece truck system for railroad cars provides long travel side bearings for improved stability, a nullwidenull friction shoe design or equivalent to improve sideframe and bolster squareness, a resilient pedestal pad for improved curving performance and enhanced wear resistance, and a suspension system tuned and optimized for rail cars to have a minimum reserve capacity of less than 1.5 to improve motion control and ride quality, increase resistance to suspension bottoming, and increase hunting threshold speed. Such a motion control truck system is able to meet recent, more stringent American Association of Railroads standards, such as M-976, for railcars having a 286,000 lb. gross rail load rating.

Abstract: A long travel constant contact side bearing for railway cars provides better handling characteristics, achieving improved tracking and curving through use of various combinations of features. Such a long travel side bearing is able to meet recent stringent American Association of Railroads standards, such as M-976. Lowered spring rates, preferably less than 6,000 lb/in., help with stability and reduce set-up sensitivity. Reduced cap and base dimensions and spring design help achieve travel of at least nullnull. A visual inspection windows allows ready inspection. Increased service life and wear characteristics are obtained by addition of hardened wear surfaces, improved tolerances, changes to Grade E steel, increase of top contact surface flatness and coped top surface peripheral edges. Standardized sets of spring components can be mixed and matched, requiring fewer specialty parts. Interchangeability of improper components can be prevented by a combination of keying features and/or spring lockout features.

Abstract translation: 用于铁路车辆的长行程恒定接触侧轴承提供更好的操纵特性，通过使用各种特征组合来实现改进的跟踪和弯曲。 这样长的旅行侧轴承能够满足近期严格的美国铁路协会标准，如M-976。 降低的弹性系数，优选小于6,000磅/英寸，有助于稳定性和降低设置灵敏度。 减少盖和底座尺寸和弹簧设计有助于实现至少5/8“的行程。 目视检查窗口可以准备检查。 通过添加硬化磨损表面，改善公差，改变E级钢，增加顶部接触表面平整度和处理的顶部表面周边边缘，可以获得更高的使用寿命和磨损特性。 标准的弹簧组件可以混合和匹配，需要较少的专业零件。 可以通过键控特征和/或弹簧锁定功能的组合来防止不正确的部件的互换性。
