Patent ID: 7458477

Claim:
An automatic central buffer coupling for a multi rail vehicle, comprising: a coupling head for a mechanical and force-fit coupling of a first car body with an adjacent second car body, said coupling head having centering elements designed as a pin/socket arrangement for pre-centering and precision centering; a supporting unit arranged underneath said coupling head having at least one of a hydraulic and compressed air terminal for at least one of a hydraulic and compressed air line; an electrical contact carrier arranged underneath said supporting unit and guided so as to be displaceable in a longitudinal direction of said central buffer coupling, said electrical contact carrier having contact terminals for electrical connections; and an actuating device for a displacement of the electrical contact carrier in the longitudinal direction, said actuating device being one of a hydraulically controllable actuating device and a pneumatically controllable actuating device, and further being controllable by means of at least one of the hydraulic and compressed air line, wherein the electrical contact carrier is in an uncoupled position behind a coupling plane of the central buffer coupling in an uncoupled state; wherein the electrical contact carrier is displaceable from an uncoupled rearward position into a coupled forward position in the coupling plane by means of the actuating device; and wherein the centering elements serve simultaneously as a trigger device for triggering a coupling mechanism for coupling of at least one of the hydraulic and the compressed air line upon mechanical coupling of the adjacent first and second car bodies, wherein an adjusting pin, which is displaceable in the longitudinal direction of said central buffer coupling, is accommodated in the socket of the pin/socket arrangement, which socket, upon coupling to the adjacent car body, receives the pin of the adjacent car body arranged in a correspondingly complementary manner, said adjusting pin being displaced away from the coupling plane upon the mechanical coupling of the adjacent first and second car bodies by a penetrating pin of the adjacent car body and thereby triggering the coupling mechanism.
