摘要： An electric machine has a stator and a rotor. The rotor is arranged on a rotor shaft that can be rotated about an axis of rotation. The stator surrounds the rotor radially on the outside with respect to the axis of rotation. The stator is surrounded radially on the outside by a one-piece housing with respect to the axis of rotation. As viewed around the axis of rotation, the housing extends only over a partial angular range. As viewed around the axis of rotation, a remaining angular range, in which the stator is not surrounded by the housing, thus remains. In end regions located at the ends of the partial angular range, the housing has housing-side form-closure elements, which cause a form closure of the housing with the stator in interaction with stator-side form-closure elements.

摘要： A double axle drive includes at least one driving motor arranged between two drive axles, wherein the axis of rotation thereof extends transversely, in particular perpendicularly to the drive axles, where a wheel set shaft is drivable via a drive shaft of the driving motor via each transmission, and where the entire double axel drive is arranged in a housing unit that includes two housing parts.

摘要： A slip coupling includes two coupling elements and a clamping nut screwed onto one coupling element to press the other coupling element against the one coupling element so that a torque acting on one coupling element is transmitted slip-free to the other coupling element and limited to a sliding torque as the coupling elements slip against one another. Free play disks are disposed between the clamping nut and the other coupling element. Interacting driver elements received by the clamping nut, the free play disks and the other coupling element enable the coupling elements to slip against one another up to a critical angle without rotation of the clamping nut. When clamping nut is caused to rotate, a contact pressure of the other coupling element on the one coupling element and thereby a holding torque transmittable in a slip-free manner is changed.

摘要： A drive of a rail vehicle includes two drive wheels and a wheel set shaft which connects the drive wheels for rotation about an axis. A dynamoelectric machine includes a shaft extending axially parallel to the wheel set shaft and mounted for rotation about a further axis. A transmission connects the shaft of the dynamoelectric machine and the wheel set shaft by a non-positive fit. Placed between the dynamoelectric machine and the transmission is a coupling which is configured for direct attachment of a brake disk of a braking apparatus which is arranged between the transmission and the dynamoelectric machine.

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).
