摘要： A connection between a draft sill (80;180;314) and a railway wheel bogie is disclosed. The draft sill (80; 180;314) has a bottom and side walls extending up from the bottom. A center pin (90;190;310) extends downward from the bottom to an exterior end surface. A boss (88;188;300) encircles the center pin (90;190;310). The boss (88;188;300) is attached to the outer surface of the center pin (90;190;310) and to the bottom surface of the draft sill (80;180;314). The boss (88;188;300) includes a plurality of ribs (102;202) extending radially outward from the center pin (90;190;310). The total surface area of the horizontal surfaces of the boss (88;188;300) and the center pin (90;190;310) is less than 98 square inches. The horizontal surfaces of the boss (88;188;300) and center pin (90;190;310) do not bear any vertical load under normal conditions, and no center plate is provided. The center pin (190;310) and boss (188;300) can be integral, and can be made to extend upward from the bogie bolster to be received in an opening in the draft sill (314).

摘要： A rotary railway coupler (10) is provided having compound fillets (94, 96) of variable increasing radii of curvature inserted between the shank (84) and the butt end (54) of the coupler (10). The compound fillets (94, 96) reduce the stress concentration between the shank (84) and the butt end (54) of the coupler (10) by distributing the stress over a greater curved surface area in order to decrease the possibility of fatigue cracking and failure at the transition surface between the coupler shank (84) and butt end (54). The compound fillet (94, 96) may also be arranged to undercut the surfaces (78, 80, 86, 88) of the coupler shank (84) and butt end (54) in order to reduce metal build-up at this location.
摘要翻译：一种旋转铁路联接器（10），其具有插入在联轴器（10）的柄（84）和对接端（54）之间的可变增加曲率半径的复合圆角（94,96）。复合圆角（94,96）通过在更大的曲面上分布应力来减小连杆（10）的柄（84）和对接端（54）之间的应力集中，以减少疲劳开裂的可能性以及在联接器柄（84）和对接端（54）之间的过渡表面处的故障。复合圆角（94,96）还可以布置成对联接器杆（84）和对接端（54）的表面（78,80,86,88）进行底切以减少在该位置处的金属积聚。

摘要： A tapered wear liner and articulated connector using such a tapered wear liner are disclosed. The tapered wear liner (78) supports an annular bearing that supports the male connecting member (32) of the articulated connector (10). The tapered wear liner (78) has an outer surface that may be shaped as the frustum of a cone or the frustum of a sphere. The female connecting member (34) has a complementary shaped groove (80) to receive the tapered wear liner (78). The female connecting member (34) has a bottom wall (68) with a substantially uniform thickness from the wear liner (78) to the exterior surface of the female connecting member (34). A main pin (40) connects the male and female connecting members (32,34) together and a center pin (100) is integral with the main pin (40) and connected to the railroad car truck. The present invention is useful with railroad car trucks that have concave curved center plate areas.

摘要： A railway car with a slackless drawbar arrangement for unit trainservice and the like is provided and includes a drawbar (15) having a section (50) which is fabricated. The fabricated intermediate section (50) is cut from a section of seamless pipe or tubing or can be fabricated from plate, while the coupling end pieces (16,18) attached to each end of the shank are at least partially 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 is part of the body of the coupling end pieces, thereby reducing the railcar's weight and costs to manufacture.

摘要： Center filler plates (16;50;50') for mounting on draft sills of railway car underframes are disclosed. The center filler plates have four pockets (96,96') surrounding a hub (62,62'). The pockets are shallower than in the prior art, and the walls defining the pockets (96,96') meet in radii having larger radii of curvature than in the prior art. The shallower pockets (96,96') and larger radii of curvature facilitate removal of the casting from the molding sand in the cope and drag sections of the mold. The formation of burned-in sand is limited in the present invention, and any burned-in sand that does form is also more easily removed from the center filler plates of the present invention. The base portion of the center filler plates (50,50') is not as high as in the prior art. The ribs (90,90') of the center filler plate and the walls of the hub (62,62') are thicker than in the prior art to provide the needed strength to the center filler plates. In one embodiment, the ribs (90) taper toward the hub (62), and the hub is shorter than the surrounding web (76); a tool may be inserted through the kingpin hole, expanded to bear against the tapered surfaces of the ribs (90); a machine may be used to lift the center filler plate and move it into position on the draft sill. The tool may then be contracted and removed, and the center filler plate may be secured to the draft sill through welding or other techniques.
摘要翻译：公开了用于安装在铁路车底架的通风槽上的中心填充板（16; 50; 50'）。中心填充板具有围绕毂（62,62'）的四个凹穴（96,96'）。口袋比现有技术浅，并且限定凹穴（96,96'）的壁与半径相符，其比现有技术具有更大的曲率半径。较浅的凹穴（96,96'）和更大的曲率半径有助于从模具的上模和拖曳部分中的型砂移除铸件。在本发明中，烧成砂的形成受到限制，也可以从本发明的中心填充板更容易地除去任何形成的烧成砂。中心填充板（50,50'）的基部不像现有技术那样高。中心填充板的肋（90,90'）和毂（62,62'）的壁比现有技术中的厚，以向中心填充板提供所需的强度。在一个实施例中，肋（90）朝着轮毂（62）逐渐变细，轮毂比周围的腹板（76）短。一个工具可以插入穿过主销孔，膨胀以抵靠肋（90）的锥形表面; 可以使用机器来提升中心填充板并将其移动到起草条上的适当位置。然后可以将工具收缩和移除，并且中心填充板可以通过焊接或其它技术固定到通风门。

摘要： The present invention relates to a railway car coupler arrangement whereby a standard yoke, follower, and draft gear are removed from the center sill and replaced with a short yoke member (30), a spacer block member (70) and slackless drawbar arrangement, namely, a pocket casting wedge shim (60), and follower (50), easily converting the coupler arrangement to a drawbar arrangement without modifying the center sill. The short yoke (30), spacer block (70) and slackless arrangement fit exactly within the space formerly occupied by the draft gear pocket casting. The drawbar arrangement maintains the same degrees of angling freedom as the coupler since the drawbar is connected and pivoted from the same pin location as when the coupler was installed. The short yoke member (30) is also designed to more uniformly distribute draft loads to the center sill by transferring forces from the connecting pin into the short yoke member, which in turn transfers those forces into abutting center sill front stops, left intact from the coupler arrangement. The present invention further provides a quick method for converting a broken coupler to a drawbar arrangement for towing back to a repair shop.
摘要翻译：铁路车辆联接装置本发明涉及一种铁路车辆联接装置，其中标准的轭架，从动件和牵引装置从中间梁移除并用短轭架构件（30），间隔块构件（70）和松弛的牵引杆装置，口袋铸造楔形垫片（60）和从动件（50），在不修改中心梁的情况下容易地将联接器装置转换成牵引杆装置。短轭（30），间隔块（70）和无间隙布置恰好配合在先前由抽风齿轮袋铸件占据的空间内。牵引杆装置保持与牵引装置相同的成角度自由度，因为牵引杆从与安装耦合器时相同的销位置连接并枢转。短轭架构件（30）还被设计成通过将来自连接销的力传递到短轭构件而更均匀地将牵引载荷分配到中梁，所述短轭构件又将这些力转移到邻接的中央门槛前挡块，耦合器布置。本发明进一步提供了一种用于将断开的联接器转换成用于拖回修理厂的牵引杆装置的快速方法。
