摘要： A bogie (6) comprises a bogie frame (7). The bogie frame (7) is mounted on bearings (7b) via a first spring device (7a). A wheelset shaft (8) is mounted in the bearings (7b). A wheelset drive (9) concentrically surrounds the wheelset shaft (8) and acts thereupon. The wheelset drive (9) is spring-mounted on the bearings (7b) by means of a second spring device (16) exclusively associated with the wheelset drive (9). A two-level clutch (15) is arranged between the wheelset drive (9) and the wheelset shaft (8).
