Junction of a pylon with an aircraft wing

A junction of a pylon with an aircraft wing, the pylon comprising a primary structure that extends from front to rear along a longitudinal axis and that is in a form of a box with a rear face and an upper spar forming an upper face of the box, a longitudinal median plane separating the primary structure into two parts, left and right, the junction comprising a front attachment system for attaching the pylon to the wing, the front attachment system being on the upper face of the box, halfway along the primary structure, a rear attachment system for attaching the pylon to the wing, the rear attachment system being at the rear of the primary structure, and an intermediate attachment system for attaching the pylon to the wing, the intermediate attachment system being on the upper face of the box between the front and rear attachment systems, the rear attachment system comprising a shoe attached beneath the wing and a fitting attached to the rear face of the pylon, the shoe being connected, via at least one articulated connecting rod, to the fitting by an articulation with a horizontal articulation pin perpendicular to the longitudinal median plane, the shoe being connected to the upper spar via a force reacting system, wherein the force reacting system comprises an extension extending the upper spar of the pylon towards the rear and a spreader, the shoe being articulated, through the spreader, to the extension via an articulation with a vertical articulation pin parallel to the longitudinal median plane.
