Abstract

ATTACHE MOTEUR POUR UN MOTEUR D’UN AERONEF COMPORTANT UNE BIELLE ET UN SYSTEME DE MAINTIEN DE LA BIELLE L’invention concerne une attache moteur (200) fixée entre un mât et un moteur d’un aéronef. L’attache moteur (200) comporte une poutre (152) fixée au mât et comportant une chape (158) en forme de U avec deux parois parallèles et un fond et chaque paroi de la chape (158) est traversée par un alésage, une bielle avec une première articulation disposée au niveau d’une première extrémité de la bielle et logée dans la chape (158) où la bielle présente un premier flanc et un deuxième flanc et où chaque flanc est en regard d’une paroi de la chape (158), et un système de maintien (250) comportant un étrier (251) en U avec deux parois latérales (252a) reliées par une paroi de fond (254), et pour chaque paroi latérale (252a), une languette élastique (258a) solidaire de la paroi latérale (252a) et qui s’étend vers l’autre paroi latérale, où l’étrier (251) est positionné à l’intérieur de la chape (158) où chaque paroi latérale (252a) de l’étrier (251) est contre la face intérieure d’une paroi de la chape (158) et où la paroi de fond (254) de l’étrier (251) est contre le fond de la chape (158), où chaque paroi latérale (252a) est traversée par un alésage coaxial avec l’alésage de la paroi de la chape (158). Ainsi, les languettes disposées de part et d’autre de la bielle maintiennent ladite bielle dans une position normale de fonctionnement. Fig. 3ENGINE ATTACHMENT FOR AN ENGINE OF AN AIRCRAFT CONTAINING A ROD AND A ROD HOLDING SYSTEM The invention relates to an engine attachment (200) fixed between a mast and an engine of an aircraft. The engine attachment (200) comprises a beam (152) fixed to the mast and comprising a U-shaped yoke (158) with two parallel walls and a bottom and each wall of the yoke (158) is traversed by a bore, a connecting rod with a first articulation arranged at a first end of the connecting rod and housed in the yoke (158) where the connecting rod has a first side and a second side and where each side faces a wall of the yoke ( 158), and a holding system (250) comprising a U-shaped yoke (251) with two side walls (252a) connected by a bottom wall (254), and for each side wall (252a), an elastic tongue (258a) ) integral with the side wall (252a) and extending towards the other side wall, where the yoke (251) is positioned inside the yoke (158) where each side wall (252a) of the yoke (251) is against the inside face of a wall of the yoke (158) and where the bottom wall (254) of the yoke (251) is against the bottom of the yoke (158), where each side wall (252a) is traversed by a bore coaxial with the bore in the wall of the yoke (158). Thus, the tabs arranged on either side of the connecting rod keep said connecting rod in a normal operating position. Fig. 3
