An underneath type railway freight car bogie wheelset radial device has front and rear subframes and two cross-arranged connecting rods that are pinned by round pin connectors. The subframe is a combination structure of the adapter and the lateral arm. The connecting rods are arranged under the bolster to form the underneath bogie wheelset radial structure. The height of the central plane of the connecting rod is lower than the height of the central plane of the subframe adapter surface. The adapter has an adapter surface forming an arc-shaped adapter structure and an adapter connecting arm integrated with the adapter surface structure and vertically arranged at one end of the adapter surface; the subframes are fixed to the adapter by the rivet assembly.

Underneath type railway freight car bogie wheelset radial device

A sub-frame radial bogie comprises wheelsets, a side frame, a swing bolster, a wheelset radial device and a brake gear. Bearing adapters () forming the wheelset radial device are fixedly connected with the sub-frame () via pulling rivets (), and each group of the bearing adapters () is bilaterally symmetrical in structure with a symmetry plane (A). The sub-frame () comprises an arm () and an end (); a sub-frame connection hole () is arranged on the end (); transverse positioning bosses () are arranged on the bearing adapters (); and an arc groove () and symmetrical sub-frame connection holes () are arranged on a connection base (). The bearing adapters use the same standard structure, hence, the more precise design and machining can be realized, and the cost is reduced, and meanwhile, the maintenance technique of the sub-frame is improved, and the maintenance cost is reduced.
