An arrangement for a rail vehicle has an electric hollow-shaft motor with a hollow rotor and a wheelset shaft that runs through the hollow rotor. The rotor is separated from the wheelset shaft at least in certain sections by a radial air gap which ensures a mechanical clearance between the wheelset shaft and the rotor. A protective material is arranged in the region of the radial air gap between the rotor and the wheelset shaft. The protective material, in the event of failure of a motor fastening of the hollow-shaft motor and subsequent support of the rotor on the wheelset shaft, separates the rotor from the wheelset shaft. The protective material is softer than the material of the wheelset shaft and softer than at least one material of the rotor.

A drive assembly is provided for a rail vehicle, having at least one motor, at least one wheel set shaft or at least one rail vehicle wheel, and at least one elastic coupling that has at least one elastic device, wherein the at least one elastic coupling is embodied to couple the at least one motor directly to the wheel set shaft or directly to the at least one rail vehicle wheel.

A thread-reinforced joint device for a coupling device of a vehicle drive, particularly of a low-platform vehicle, includes a plurality of coupling elements, at least one thread packet coupling two adjacent coupling elements so that a force is transmittable, a support device arranged on at least one of the coupling elements for axially guiding the at least one thread packet and at least one elastic body, into which, the at least one thread packet and the coupling elements are at least partially embedded. The coupling elements are designed and/or can be positioned so that the thread-reinforced joint device is adaptable to different mounting interfaces of a respective coupling device.

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.
