摘要： A motorized swivel truck for rail vehicles, especially streetcars, having a truck frame on which a cradle frame lying transversely of the direction of travel is supported by an air spring bellows, and the car body rests upon the cradle frame through an annular ball bearing which permits wide swiveling of the swivel truck. The swivel truck frame consists of two longitudinal members having a generally underslung configuration and whose middle, underslung portion has an open cross-sectional profile, and two transverse members which are disposed between the wheel axles and have a likewise open cross-sectional profile and which have a generally arched configuration, and whose ends are welded to the end portions of the longitudinal members. Owing to the underslung and arched configurations and the open crosssectional profiles the swivel truck frame is flexible, so that the wheel bearings may be mounted with very stiff springing in the end portions of the longitudinal members. The motor is suspended on the cross members by resiliently yielding means such that its drive shaft lies parallel to the direction of travel, the driving of the wheel axles is performed through a bevel gear transmission and a flexible coupling, and the air spring bellows are located adjacent the ends of the cradle frame.
摘要翻译： 一种用于轨道车辆，特别是有轨电车的电动转轨车，具有一个卡车框架，一个位于横向于行进方向的托架框架由空气弹簧波纹管支撑，汽车车身通过环形滚珠轴承支撑在托架架上， 允许旋转卡车的广泛旋转。 旋转车架包括两个纵向构件，其具有大体上下方的构型，并且其中部下凸部具有敞开的横截面轮廓，以及两个横向构件，其设置在轮轴之间并具有同样敞开的横截面轮廓， 具有通常的拱形构造，并且其端部焊接到纵向构件的端部。 由于凸起和拱形构造以及开放的横截面轮廓，转向架框架是柔性的，使得车轮轴承可以在纵向构件的端部中以非常硬的弹簧安装。 电动机通过弹性制动装置悬挂在横梁上，使得其驱动轴平行于行进方向，通过伞齿轮传动装置和柔性联轴器来执行轮轴的驱动，空气弹簧波纹管位于 邻近支架框架的端部。

摘要： A center plate structure for a railway car having a bowl on the truck bolster to receive a center plate on the car body. A bearing insert for the body center plate is positioned within the bowl in a freely floating relation to the bowl and is movable within the bowl in a generally horizontal relation. The bearing insert has an upper convex surface which mates with a concave lower surface on the body center plate to permit a relative tilting movement between the body center plate and the bearing insert on the truck bolster.

摘要： A unit train having a plurality of articulated cars for transporting one commodity or lading in one direction of travel between two geographical areas, and a different lading in the return opposite direction of travel. Alternate freight cars of one type, such as hopper cars, are transported in an unloaded condition in one direction of travel and are transported in a loaded condition in the return opposite direction of travel. Intervening freight cars such as flat cars, are transported in a loaded condition when the alternate cars are in unloaded condition, and are transported in an unloaded condition when the alternate cars are in loaded condition. The articulated cars have common trucks between adjacent ends of all the cars in the unit train to support the ends thereon. The trucks have a load capacity adequate to support one of the supported cars in fully loaded condition but inadequate to support both of the supported cars in loaded condition.
