Abstract
The present invention relates to an automatic central buffer coupling, especially of the 'Tlghtlock/AAR' type of construction. The coupling includes a coupling head, with a supporting unit underneath; a hydraulic and/or compressed air terminal for a hydraulic or compressed air line; and an electrical contact carrier arranged underneath the supporting unit and having electrical contact terminals; and an actuating device to longitudinally displace the electrical contact carrier via the air line. The electrical contact carrier is in an uncoupled position rearward of the coupling plane of the central buffer coupling, and is displaceable into a coupling-ready forward position in the coupling plane via the actuating device. In order to ensure that the electrical contact carrier is automatically co-coupled after the mechanical coupling operation, a release mechanism is configured to ensure a coupling mechanism is triggered to co-couple the at least one hydraulic and/or compressed air terminal.
