摘要： A draft gear assembly is disclosed alone and in combination with a draft sill and a coupler. The draft sill has front and rear stops defining a draft gear pocket. The draft gear assembly has a yoke, a coupler follower, a rear follower, a front resilient member and a back resilient member. The yoke has top and bottom stops. The coupler follower is biased against the yoke top and bottom stops. The draft gear assembly also includes a center rod that extends through the yoke, through the back resilient member and through the rear follower. Prior to installation on a railcar, there is a shortening member on the center rod. The length of the assembly between the shortening member and the front of the coupler follower is slightly less than the longitudinal length of the draft gear pocket. After installation, the rear follower is positioned against rear stops of the draft sill. After installation, the yoke, coupler and coupler follower each have a neutral position and a full buff position. The yoke and coupler also have a full draft position. The draft stroke of the coupler and yoke is 1¼ inches forward. The buff stroke of the coupler and coupler follower is at least 4¼ inches rearward, while the buff stroke of the yoke is 3 inches rearward. The center rod is free from compression throughout buff movement and free from tension throughout draft movement of the coupler and yoke.

摘要： 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.

摘要翻译： 提供了一种常见的E / F型通式挡板，可容纳E型或F型牵引齿轮组件，包括旋转耦合器应用。 预应力槽优选铸造，但也可以制造。 普通的E / F入口底板设有一个F型入口通道的固定的一体式弹簧篮，用于容纳和容纳标准弹簧偏置弹簧篮支撑系统，并容纳标准的F型起落架。 提供F型牵引齿轮的标准垂直连接。 公共挡泥板还具有E型筛板的水平键槽，还可容纳E型牵引装置的附件。 还可以使用一个插入式E耦合器支架，代替用于F型牵引齿轮的“弹簧篮”支撑系统，以便适当支撑E型牵引装置。 可以通过在公共挡泥板上并入两个枕垫和身体支撑翼来实现额外的标准化和减少专用铸件。 可以通过提供标准化的加工后底梁垫来实现进一步的标准化，所述尾梁垫适用于具有多个不同轨道车辆规格的应用的多个不同设计规格。 可以通过具有接受多种类型的牵引齿轮应用的凸缘孔图案来实现进一步的标准化。 额外的标准化可以通过使标准化的中心框架的端部和一系列“插头接收器”组合实现，其中提供特定应用的“插头”，其可以焊接在面向公共吃水端的中心框架 将其适应特定的配置。

摘要： A double acting center-of-car cushioning device mounted in the sliding sill of a rail car includes two pistons and rods, two pressure cylinders and mirror image sets of flow orifices in the pressure cylinders. The piston rods extend out from ends of the pressure cylinders and engage a fixed sill of the rail car. Movement of the pistons within the pressure cylinders forces fluid through the flow orifices resulting in efficient dampening.
