A lower-mounted railway freight car bogie wheelset radial device, which is formed by pin-connecting front and rear sub-frames (21') and two intersected connecting rods (22'); each sub-frame is a combined structure formed by connecting bearing adapters (31) and a transverse arm (32), and the connecting rods are provided below a bolster (14) to constitute a lower-mounted radial structure; the height of the central plane of the connecting rods is lower than the height of the central plane of a sub-frame bearing adapter face (311); each bearing adapter is composed of an adapter face forming an arc-shaped adapter structure and an adapter connecting arm (312) which is integrated with the adapter face structure and is vertically provided at one end of the adapter face, and each sub-frame is fixedly connected to the adapters by means of a blind rivet assembly (33). The radial device can be well adapted to traditional lever braking and integrated braking devices, effectively improving bogie versatility, and being beneficial to bogie technical modification and product upgrade; the radial device can be assembled independently, and the bogie assembly processability is good; and the wheelset radial device can be directly separated from other bogie parts by disassembling stop keys, without damaging the structure of the other parts, thereby effectively reducing the difficulty in maintenance and inspection.
