Linking device connecting an aircraft engine and a primary structure of an aircraft pylon comprising a spreader and a system for limiting the out-of-plane deflection of the spreader, aircraft comprising such a linking device

A linking device connecting an aircraft engine and a primary structure of an aircraft pylon, comprising:

• a support connected to the primary structure,
• a spreader, extending between first and second ends, that has a central part connected to the support by a principal link comprising a principal rotation axis,
• a first thrust rod comprising a first end connected to the first end of the spreader by a first secondary link and a second end connected to the engine,
• a second thrust rod comprising a first end connected to the second end of the spreader by a second secondary link and a second end connected to the engine,
• first and second fittings, secured to the support, comprising upper and lower branches, between which the spreader is positioned,
• the linking device generating a deflection of the spreader that is configured to pivot about a deflection rotation axis perpendicular to the principal rotation axis and contained in a plane of symmetry passing via the principal rotation axis,
• wherein the linking device comprises at least one system for limiting the deflection of the spreader comprising an extension secured to the spreader and also upper and lower stops, secured to the first or second fitting, between which the extension is positioned.
