Bonjour Nesrine,

Vu le manque de contexte, il s'agit d'une suggestion.


MÉCAN. Tige d'acier forgée ou de fonte, qui, articulée à ses extrémités sur deux pièces mobiles, transmet, en le modifiant ou pas, à l'une le mouvement de l'autre

I want to make two preliminary comments:
- we're totally lacking of context
- I have the strong impression that the writer is not an native speaker of English
Having said so, I worked for 11 years for a company making those products! If I'm guessing right, due to the lack of context, here we are talking about the rod that is connecting the wheels within a steering system. This rod ends, on the wheel side, into ball rod joints. in the link below you can see an example of what I am talking about
The correct English term for this is assembly is Tie (or Track) Rod Assembly which in Italian translate into Assieme Tirante Sterzo.
Your writer has, in my opinion, mixed and matched the terms, including Mount (MNT) which hardly ever used by a native to describe ans assembly (assy, for short).
Let me know if I'm guessing right!

Thank you for the additional info. At this point I’m lost! I’m not familiar with the this technology. Sorry

D'accord avec les collègues : le contexte est trop maigre pour répondre à bon escient.
Ma supposition est qu'il s'agit d'une bielle de type "spherical-head rod", ce qui donnera bielle à rotule. Ma source est un glossaire multilingue assez fourni pour la technologie aéronautique.
