Abstract

A rail vehicle unit, having a running gear and a wagon body unit. The wagon body unit is supported on the running gear via a suspension device, a first rotational buffer device and a second rotational buffer device being associated to the running gear and the wagon body unit. The first rotational buffer device and the second rotational buffer device are adapted to damp a rotational motion between the running gear and the wagon body unit about a rotational axis parallel to the height direction. The first rotational buffer device and the second rotational buffer device are configured to form a traction link between the running gear and the wagon body unit.
