Abstract
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.
