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.

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.

The present invention discloses a freight car bogie and a freight car. The freight car bogie comprises two wheel sets, two side frames arranged at outer side of said wheel sets, and a bolster fixedly connected to center position of each of said two side frames, respectively. The freight car bogie further comprises a K-shaped supporting device, wherein said K-shaped supporting device passes through preset holes on two sides of an abdominal region of said bolster; a first upper end and a second upper end, as well as a first lower end and a second lower end of said K-shaped supporting device are elastically connected with said two side frames respectively; and said first upper end and second upper end, and said first lower end and second lower end are respectively symmetrical with respect to a centre line of said bolster. The K-shaped supporting device of the present application may not pass through the middle part of the bolster so that a reinforcing rib for bearing vertical load can be disposed on the middle part of the bolster, thereby increasing the anti-lozenge-distortion rigidity of the bogie as well as improving the strength of the bolster for bearing the vertical load.

The present invention provides an journal box rubber pad and a bogie, wherein the journal box rubber pad comprises a glue-injection hole and a conductive mechanism: the glue-injection hole comprises a cavity formed in a rubber layer, a first hole formed on an upper wear liner and a second hole formed on a lower wear liner. The cavity, the first hole and the second hole are communicated with each other; the conductive mechanism is placed internally in the glue-injection hole; the two ends of the conductive mechanism pass through the first hole and the second hole respectively and be in contact with two conducted apparatuses. The journal box rubber pad and the bogie of the present invention have the advantages that: the journal box rubber boxes not only can overcome the disadvantages that the upper and the lower wear liners are easy to be abraded and have poor contact with a bogie side frame and an adapter because of the requirements of high manufacturing accuracy but also can realize conductive function.
