Abstract

An assembly including a connecting device, connecting first and second parts, including first and second links positioned on respective opposite sides of the first and second parts and an interleaved stiffener, positioned between the first and second links, having a first contact face oriented toward the first link and a second contact face oriented toward the second link, parallel to the first face, the first and second contact faces being separated by a distance equal to that separating the first and second links. This interleaved stiffener makes it possible to limit the risks of bending of the links when they are loaded in compression.

First claim

The invention claimed is:

1. An aircraft engine attachment including at least one assembly comprising:
a first part,
a second part, and
a connecting device connecting the first and second parts,
the connecting device including:
first and second articulation elements accommodated in first and second holes through the first and second parts, and
first and second links, connecting the first and second articulation elements, positioned on respective opposite sides of the first and second parts,
the first link having a planar internal face oriented toward the second link, the second link having a planar internal face oriented toward the first link,

wherein the connecting device comprises:
an interleaved stiffener positioned between the first and second links, having a first contact face oriented toward the first link and a second contact face oriented toward the second link, parallel to the first face, the first and second contact faces being planar and separated by a distance equal to that separating the first and second links, the planar internal faces of the first and second links being held against the first and second planar contact faces of the interleaved stiffener,
the interleaved stiffener including:
a body of parallelepiped shape,
a first yoke, connected to the body, cooperating with the first part, and
a second yoke, connected to the body at an end opposite the first yoke, cooperating with the second part,
 the body, the first yoke and the second yoke forming a single part,

wherein the interleaved stiffener limits bending of the first and second links when the first and second links are loaded in compression,
wherein the interleaved stiffener enables a distance between the first and second links to remain constant in the presence of compression forces and limits transverse bending of the first and second links.

2. The assembly as claimed in claim 1 ,
wherein the first yoke comprises:
a first flange, positioned between the first link and the first part, including an orifice accommodating the first articulation element,
a second flange, positioned between the second link and the first part, including an orifice, accommodating the first articulation element, and

wherein the second yoke comprises:
a first flange, positioned between the first link and the second part, including an orifice accommodating the second articulation element,
a second flange, positioned between the second link and the second part, including an orifice accommodating the second articulation element.

3. The assembly as claimed in claim 2 ,
wherein the first and second flanges of the first and second yokes have external faces coplanar with a first face of the body oriented toward the first link, the external faces of the first flanges and the first face of the body forming the first contact face of the interleaved stiffener, and
wherein the second flanges of the first and second yokes have external faces coplanar with a second face of the body oriented toward the second link, the external faces of the second flanges and the second face of the body forming the second contact face of the interleaved stiffener.

4. The assembly as claimed in claim 1 , wherein the connecting device includes a system connecting the first and second links and the interleaved stiffener.

5. The assembly as claimed in claim 4 , wherein the connecting system includes at least one transverse connecting element passing through the first and second links and the interleaved stiffener configured to maintain the first and second links pressed against the interleaved stiffener.

6. The assembly as claimed in claim 5 , wherein the connecting system includes a plurality of transverse connecting elements divided between the first and second articulation elements.

7. The assembly as claimed in claim 4 , wherein the connecting system includes, at a level of each articulation element, a ring surrounding the articulation element onto which are force-fitted the first and second links and the interleaved stiffener.

8. The assembly as claimed in claim 1 , wherein the body of the interleaved stiffener includes at least one opening.

9. The assembly as claimed in claim 1 , wherein at least one of the first and second links includes at least one longitudinal rib on an external face of at least one of the first or second link projecting relative to that external face.
