Abstract
Linkage device for a couplings of railway vehicles, the coupling head of which is connected to a drawbar linked to a steering pivot of the railway vehicle, which drawbar is provided with spring elements sitting on it in order to dampen compressive and tensile force that arise, e.g., when coupling the railway vehicle. The spring elements are fastened to a plate that can be rotated about an axis of rotation of the steering pivot. In this way, they are also deflected when the coupling is deflected so that the compressive and tensile forces acting on the latter also act upon its entire surface evenly, even when the coupling is deflected. The linkage device is also provided with overload protection.
Claims20
A linkage device for a vehicle coupling, the linkage device comprising:
- a housing having a rotatable plate;
- a drawbar connectable to a coupling head and mounted in the plate of the housing;
- a first spring element mounted on the drawbar and configured to dampen a compressive force of a vehicle that arises during coupling;
- a second spring element mounted on the drawbar and configured to dampen a tensile force of the vehicle that arises during coupling;
- a flange with a housing connectable to the vehicle, wherein the plate in the housing is disposed between the first spring element and the second spring element;
- and
- a plastically deformable tubular body that extends from a gap between the housing and the flange to outside of the housing and the flange, wherein the tubular body is configured to absorb energy when there is overload and cooperates with a hub of the housing that penetrates into the tubular body.
