ABSTRACT:
The present invention relates to an automatic central buffer coupling for a multi-membered vehicle having a coupling head and a signal transmission device for transmitting signals between a first and a second car body. The invention integrates a signal transmission device into the central buffer coupling. The invention includes a coupling element and a counter-coupling element integrated into respective contact plates of adjacent coupling heads such that the face side of the coupling element is arranged opposite the face side of the counter-coupling element. The coupling element and the counter-coupling element each have an antenna member that includes a disc monopole antenna configured to transmit data in the GHz frequency range.
