Abstract

L'invention concerne un dispositif d'accouplement pour un véhicule sur rails destiné à être relié à un dispositif d'accouplement antagoniste d'un autre véhicule sur rails. Le dispositif d'accouplement est caractérisé en ce qu'il s'étend dans la direction longitudinale le long d'un axe longitudinal d'accouplement théorique et peut être fixé ou est articulé, dans la zone d'extrémité côté véhicule opposée à la tête d'accouplement, au moins indirectement sur le cadre de véhicule du véhicule sur rails. Le dispositif est pourvu d'une tête d'accouplement destinée à être accouplée à une tête d'accouplement du dispositif d'accouplement antagoniste, d'un dispositif de recouvrement pour la protection contre des influences ambiantes et environnementales, lequel entoure au moins en partie la tête d'accouplement. L'invention est caractérisée en ce que le dispositif de recouvrement est conçu et disposé de manière à entourer le dispositif d'accouplement au moins en partie sur toute l'étendue du dispositif d'accouplement dans la direction longitudinale et dans la direction périphérique autour de l'axe longitudinal d'accouplement au moins par endroits, ce qui entraîne la formation d'un écart par rapport à la périphérie extérieure du dispositif d'accouplement.
