The invention relates to an electrical contact coupling (3) for automatic central couplings or central buffer couplings for rail vehicles, especially for claw couplings equipped with a protective arm, a rotatable claw and with a drop latch of the "AAR" or "Janney" design or equipped with two rigid claws and claw latches of the "Willison" design comprising a contact support (8) which is fastened to the coupling head and which is guided in a longitudinally displaceable manner in a longitudinal direction of the central buffer coupling. An economical and flat-structured solution provided for constructing and configuring an electrical contact coupling (3) and an air line coupling (12) provided for a central coupling or central buffer coupling of the aforementioned type is characterized in that the longitudinally displaceable contact support (8) is arranged underneath and on a supporting unit (1) which, underneath the coupling head, is elastically supported by and fastened to the same such that at least one actuating cylinder (6) for longitudinally displacing the contact support (8) is arranged inside the supporting unit (1) and such that an air coupling (12) having an opening (11) is arranged on the supporting unit (1) in the coupling plane.

L'invention concerne un couplage par contact électrique (3) pour attelages centraux ou attelages à tampon central automatiques de véhicules sur rails, notamment pour attelages à griffes, munis d'un bras de protection, d'une griffe rotative et de loquets de type <= AAR >= ou <= Janney >= ou munis de deux griffes et de loquets de griffes fixes de type <= Willison >= comportant un porte-contacts (8) fixé sur la tête d'attelage et guidé de manière à se déplacer longitudinalement dans le sens de la longueur de l'attelage à tampon central. L'invention propose une solution avérée économique et de structure plane pour l'attelage central ou l'attelage à tampon central du type mentionné, pour former et configurer un couplage par contact électrique (3) et un couplage par conduite pneumatique (12). Cette solution se caractérise en ce que le porte-contacts (8) à déplacement longitudinal est monté en dessous et sur une unité support (1) qui s'appuie quant à elle de manière élastique sur la tête d'attelage, en dessous de ladite tête d'attelage. Il est prévu dans l'unité support (1) au moins un vérin d'actionnement (6) pour assurer le déplacement longitudinal du porte-contacts (8) et un attelage pneumatique (12) présentant une ouverture (11) débouchant dans le plan de couplage est prévu sur l'unité support (1).
