Abstract
The invention relates to devices for moving the buffers of articulated cars of railway vehicles travelling on a curve. The devices are disposed between two adjoining cars (6, 6′) articulated by a transversely centered coupling or linkage (12), said cars (6, 6′) including a front-end projecting element (9) which is joined to the coupling or linkage (12) extending from the rear end of the next car. In all embodiments of the invention, as the buffers (3) move sideways under the action of skids (2) or other means towards the center of the curve at the part of the device closest to the wheels (7) on the inner part of the curve, the sideways movement of the car into the curve is limited as the buffers (3) come into contact with the corresponding surface of the wheel set, obstructing the sideways movement of the car.
