The present invention discloses an underneath type railway freight car bogie wheelset radial device. The underneath type railway freight car bogie wheelset radial device consists of 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 consists of 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. The radial device of the present invention can better adapt to the traditional lever brakes and integrated brakes, effectively improving the versatility of the bogie and facilitating technical transformation and upgrade of the bogie; the radial device can be assembled independently, and the assembly process of the bogie is simple and convenient; the wheelset radial device and other parts of the bogie can be directly separated by removing the retaining key, without affecting the structure of other parts, effectively reducing the difficulty of maintenance.
