ABSTRACT:
Coach coupling assembly for coupling together two coaches of a railbound multi-unit set of coaches has a first coupling arm fixed to one of the coaches and a second coupling arm fixed to a second one of the coaches. The first coupling arm has a vertical through-bore that houses the outer race ring of a rolling bearing. The bore in the inner race ring of the bearing receives a depending shaft journal that is fixed to the second coupling arm. An arrangement is provided to damp radial forces acting upon the coupling and to compensate for misalignment between the axes of the through-bore and the shaft journal. In this regard, the through-bore is provided with an elastic lining of resilient material, and the bearing used is an angularly self-aligning rolling bearing that permits a certain degree of misalignment between the through-bore and the shaft journal. The bearing is fitted inside the lining, which is thereby adapted to take up and dampen radial forces acting upon the coupling.
