摘要： A freight car bogie and a freight car are provided. The freight car bogie includes two wheel set assemblies, side frames, and a bolster. The freight car bogie further includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are crossed in an X form to pass through reserved holes at two sides of a belly of the bolster. The first connecting rod and the second connecting rod are separated from each other at a crossing portion. The first connecting rod includes a first end and a second end. The second connecting rod includes a third end and a fourth end. The first end and the third end are resiliently connected to one of the side frames and symmetrical about a center line of the bolster. The second end and the fourth end are resiliently connected to the other side frame and symmetrical about the center line of the bolster. Therefore, a warp resistant rigidity of the freight car bogie is increased, and an operation speed and capability for adapting to track irregularities of a three-piece casting steel bogie are raised.

摘要： A central suspension device, a wagon bogie and an express railway wagon, wherein the central suspension device is arranged between a frame and a bolster of the wagon bogie and comprises a rubber-metal pad spring group composed of at least two rubber-metal pad springs, a bottom end of each rubber-metal pad spring is connected with the frame, a top end of at least one rubber-metal pad spring of the rubber-metal pad spring group is connected with the bolster, and a gap exists between the top end of at least one rubber-metal pad spring and the bolster. The central suspension device has multiple stages of rigidities in the transverse and vertical directions, so that the different rigidities can be mutually shifted conveniently on the empty vehicle condition and the heavy-load condition of the vehicle, therefore, the central suspension device is applicable to express railway vehicles for safe and stable running.
摘要翻译：中央悬挂装置，货车转向架和快速铁路货车，其中中央悬挂装置布置在货车转向架的框架和支架之间，并包括由至少两个橡胶 - 金属垫弹簧组成的橡胶 - 金属垫弹簧组每个橡胶 - 金属垫弹簧的底端与框架连接，橡胶 - 金属垫弹簧组的至少一个橡胶 - 金属垫弹簧的顶端与垫片连接，顶部之间存在间隙至少一个橡胶 - 金属垫弹簧和枕垫的端部。中央悬挂装置在横向和垂直方向上具有多个刚度的刚度，使得在空车辆状态和车辆的重载状态下，不同刚性可以方便地相互移位，因此，中央悬架装置适用于快速铁路车辆安全稳定运行。
