  • Publication number: 20200231187
    Abstract: A bogie wheelset radial mechanism with a structure of adjustable rigidity, composing two secondary frames (21) which are pin-connected via two connecting rods (22) arranged in a crosswise manner. The connecting rods (22) are pin-connected to the secondary frames (21) with round pins (24). Joints between the round pins (24) and the connecting rods (22) and/or joints between the round pins and the secondary frames (21) are provided with replaceable elastic materials. The materials can be made into rings. End portions of the connecting rods (22) are embedded into mounting grooves (25) located in the secondary frames (21) and are connected to the same with the round pins (24).

  • Patent number: 9802626
    Abstract: A sub-frame radial bogie comprises wheelsets, a side frame, a swing bolster, a wheelset radial device and a brake gear. Bearing adapters (41) forming the wheelset radial device are fixedly connected with the sub-frame (42) via pulling rivets (11), and each group of the bearing adapters (41) is bilaterally symmetrical in structure with a symmetry plane (A). The sub-frame (42) comprises an arm (51) and an end (52); a sub-frame connection hole (61) is arranged on the end (52); transverse positioning bosses (73) are arranged on the bearing adapters (41); and an arc groove (75) and symmetrical sub-frame connection holes (71) are arranged on a connection base (72). 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.
