摘要： A railcar truck side frame has a pedestal jaw arrangement, which inclines the bearing adapter for the axle and bearing assembly with a relative slope in the side-frame longitudinal direction, to provide transfer of the forces causing angular displacement of the axle to stop lugs on the side-frame outer surface and to minimize axle angular displacement and, consequently, truck warping and hunting.

摘要： An integrally cast bearing adapter arrangement is provided in the pedestal of a railcar truck side frame, which side frame is cast with a pedestal jaw having a roof, and vertical walls of a first and second leg which roof and walls operate as a bearing adapter to receive a bearing assembly for an axle end without introducing the manufacturing and assembly tolerances from discrete component assemblies, thereby avoiding the lateral displacement associated with the added tolerances and operating to minimize angular displacement between each mated axle and side frame.

摘要： A structural device is attached to each sideframe pedestal jaw of a railcar truck wherein the bearing adapter is joined to the sideframe and is prevented from rotating within the pedestal jaw opening. The bearing adapter inboard and outboard faces maintain a parallel relationship with the sideframe inboard and outboard faces during operations, including curving, thereby causing the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck wheel misalignment, which directly effects truck hunting and curving.

摘要： A railway car with a slackless drawbar arrangement for unit trainservice and the like is provided and includes a drawbar having a section which is fabricated. The fabricated intermediate section is cut from a section of seamless pipe or tubing or can be fabricated from plate, while the coupling end pieces attached to each end of the shank are cast members made from typical casting methods. The coupling end pieces can be cast into standard fixed or rotatable drawbar ends or even be a combination thereof with rotational capability. The geometric shape of the intermediate section is varied, depending upon the application, so that resistance to torsional or bending loads is maximized. The fabricated shank portion is hollow, as well as part of the body of the coupling end pieces, thereby reducing the railcar's weight and costs to manufacture.

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： An interface between the end of a bolster and a side frame column for a three-piece railcar truck assembly is disclosed. The bolster and side frame have several pairs of facing stop surfaces at the interface. Each pair of facing stop surfaces are at two different spacings: one spacing is close, with a small gap between the stop surfaces; another spacing is greater than the first. The second spacing allows the side frame to pitch with respect to the bolster transverse axis. The bolster stop surfaces may be the lands inboard and outboard of the friction shoe pockets. The lands may be shaped so that there is a raised warp control portion or surface and one or more relief portions or surfaces, the warp control portion extending farther laterally than the relief portions. The warp control portion is used to maintain the truck in a square relationship, and the more loosely spaced relief portions allow for side frame articulation as the truck traverses track at different elevations. The raised warp control portions and reliefs may alternatively or also be formed on the side frame lands or wear plates.
摘要翻译： 公开了一种用于三件式轨道车辆卡车组件的摇枕的端部和侧框架之间的接口。 垫子和侧框架在接口处有几对相对的止动表面。 每对相对的停止表面处于两个不同的间隔：一个间隔靠近，止动表面之间具有小的间隙; 另一个间距大于第一个间距。 第二间隔允许侧框架相对于摇枕横向轴线间距。 扶手停止表面可以是摩擦鞋袋内侧和外侧的平台。 这些焊盘可以被成形为具有凸起的翘曲控制部分或表面以及一个或多个浮雕部分或表面，所述翘曲控制部分比所述浮雕部分更远地延伸。 翘曲控制部分用于将叉车保持为正方形关系，并且随着卡车在不同高度处横越轨道，越松开间隔的释放部分允许侧框架铰接。 凸起的翘曲控制部分和凸起可以或者也可以形成在侧框架平台或耐磨板上。

摘要： A sideframe pedestal jaw accommodates a bearing adapter which locks the adapter to the sideframe, thereby preventing it from all forms of movement within the pedestal jaw opening. Locking the bearing adapter forces the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck warpage, which induces wheel misalignment that leads to undesirable truck hunting and high speed instability.
摘要翻译： 侧框架底座容纳将适配器锁定到侧架上的轴承适配器，从而防止其在基座颚开口内的所有形式的移动。 锁定轴承适配器迫使卡车轴相对于侧框保持直角。 保持这种正确的角度关系基本上限制卡车翘曲，这导致车轮未对准，导致不期望的卡车起搏和高速度不稳定性。
