Abstract: An electrical machine has a braking element and a release device. A rotor of the electrical machine includes the braking element and release device. The electrical machine is located, for example, in a rail vehicle. In order to brake the rotor of the electrical machine in the event of an error in the drive train, an overload torque is generated by the electrical machine. An overload clutch is triggered by the overload torque.

Abstract: 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).
