Abstract
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.
