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 ⅝″. 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。

Abstract: A tuned spring group with load springs, control springs, and a frictional damping arrangement for a railcar truck assembly provides better ride quality, increased resistance to suspension bottoming, and increased hunting threshold speed of a railroad car. Specifically, this tuned damping and suspension arrangement provides a spring group reserve capacity of less than 1.50. Spring assemblies for different car types are tuned such that a reserve ratio less than 1.50 may be achieved. By reducing the spring assembly reserve capacity for a railcar and truck of a standard weight and configuration to less than 1.50, an unexpected result of a decrease in maximum vertical acceleration as the railcar truck assembly approaches a speed of 55 miles per hour is achieved. The decrease in vertical acceleration allows for improved ride quality, increased resistance to suspension bottoming and increased hunting threshold speed of the railcar.

Abstract: Split wedges biased against sloped upper surfaces and the side walls of pockets in the ends of the bolster of a rail car truck are provided with non-metallic wear plates which interface with pocket side walls to reduce or eliminate pocket side wall wear. The wear plates are typically cast polymeric pads selected from the group comprising nylon, Delrin, UHMW and urethane, have a hardness in the range of between about 700° and 900° and a sliding coefficient of friction of about 0.10 to about 0.30. The pads are mounted in recesses within the sidewalls of the wedges and are held in place by means such as threaded fasteners for ease of replacement.

Abstract: A common E/F type draft sill is provided that accommodates either Type E or Type F draft gear components, including rotary coupler applications. The draft sill is preferably cast, but may also be fabricated. The common E/F draft sill is provided with a fixed, integral spring basket of a Type F draft sill to accommodate and house standard spring-biased spring basket support systems and accommodate standard Type F draft gear. Standard vertical connection of Type F draft gear is provided. The common draft sill is also provided with the horizontal keyslot of a Type E draft sill to also accommodate attachment of Type E draft gear. A drop-in E coupler support is also available that replaces the “spring basket” support system used with Type F draft gear so as to allow proper support of Type E draft gear. Additional standardization and reduction of specialized castings can be achieved by incorporating both body bolster pads and body bolster wings on the common draft sill. Further standardization can be realized by providing a standardized machined end sill pad that accommodates a plurality of different design specifications for application with a plurality of different railcar specifications. Even further standardization can be realized by having flange hole patterns that accept multiple types of draft gear applications. Additional standardization can be achieved by having a standardized center sill facing end and a series of “plug-n-receiver” combinations in which an application-specific “plug” is provided that may be welded on the center sill facing end of the common draft sill to adapt it to a particular configuration.
