Patent number: 9802626Abstract: 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.Type: GrantFiled: April 4, 2013Date of Patent: October 31, 2017Assignee: CRRC MEISHAN CO., LTD.Inventors: Tao Deng, Shuping Pan, Aimin Wang, Pu Wang, Yungui Wang, Hengli Li, Xianfeng Zhang, Hanjiang Luo, Ji Zhu, Zongquan Zhou, Chengyong Liu
