Abstract

Die Erfindung betrifft eine automatische Kupplung (1) für Schienenfahrzeuge mit Seitenpuffern (7, 8) zur Aufnahme der Druckkräfte, wobei jede Kupplungshälfte mit einem Kupplungskopf (4) und einer Zugeinrichtung (5) zur Übertragung der Zugkräfte auf den Fahrzeugkasten versehen ist. Zwischen dem Kupplungskopf (4) und der Zugeinrichtung (5) ist eine Freihubvorrichtung (6) mit einem axial verschiebbaren Pneumatikzylinder (14) eingebaut, der stirnseitig am Kupplungskopf (4) befestigt ist und dessen Kolben (15) mit der Zugstange (10) der Zugeinrichtung (5) verbunden ist, wobei der Kuppelvorgang durch Belüften des Zylinders (14) vollzogen wird, während durch Entlüften des Zylinders ein kraftloser Freihub der Kupplung erzeugt wird, der im Betrieb stellt, dass keine Druckkräfte über die Zugkupplung in das Fahrzeug eingeleitet wird, der beim Kuppelvorgang in Kurven den Puffereffekt aufhebt und zudem den Betrieb der Kupplung als reine Zugkupplung sicherstellt.

Figure imgaf001
The invention relates to an automatic coupling (1) for rail vehicles with side buffers (7, 8) for receiving the compressive forces, each coupling half is provided with a coupling head (4) and a pulling device (5) for transmitting the tensile forces on the vehicle body. Between the coupling head (4) and the traction device (5) a free lifting device (6) with an axially displaceable pneumatic cylinder (14) is installed, which is fastened to the front of the coupling head (4) and the piston (15) with the tie rod (10) Pulling device (5) is connected, wherein the dome operation is performed by venting the cylinder (14), while by venting the cylinder, a powerless free lift of the clutch is generated, which is in operation that no pressure forces on the traction coupling is introduced into the vehicle, which eliminates the buffering effect during the dome operation in curves and also ensures the operation of the clutch as a pure traction clutch.
