Abstract

La présente invention porte sur un train d'atterrissage doté d'un logement de train d'atterrissage et d'une tige de connexion ayant un premier et un deuxième levier de commande, le premier levier de commande étant directement ou indirectement relié au logement de train d'atterrissage et le deuxième levier de commande directement ou indirectement relié à la tige de connexion et un amortisseur de vibrations qui a un logement et un élément d'amortissement, l'élément d'amortissement étant déplaçable dans la zone remplie de liquide, préférablement une zone remplie d'huile de l'amortisseur de vibrations, de sorte que le mouvement de l'élément d'amortissement est amorti par le fluide, et le premier ou le deuxième levier de commande étant indirectement ou directement connecté au logement et l'autre levier de commande relié directement ou indirectement à l'élément d'amortissement, et un réservoir de fluide, préférablement un réservoir d'huile, qui est connecté avec la zone remplie de fluide, le réservoir de fluide étant intégré dans le logement de l'amortisseur de vibrations.
