Adapter for a wheeled assembly and a wheeled assembly comprising same

An adapter for a rolling assembly having an axis of rotation and comprising a tire having two beads and a rim having two rim bead seats, the adapter providing, for each bead, the connection between a bead and a rim, and the adapter having:

• an axially inner end comprising an inner reinforcing element connected to the rim;
• an axially outer end comprising an outer reinforcing element and intended to come into contact, via a substantially radially extending axially inner face with the bead, the substantially radially extending axially inner face being a bearing face;
• and
• a body connecting the axially outer end to the axially inner end, comprising at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and comprising a substantially axial adapter seat intended to come into contact with the bead,
• wherein the outer reinforcing element is completely axially on the outside of the bearing face and completely axially on the outside of a rim flange, and
• wherein the outer reinforcing element is a substantially annular structure of substantially polygonal section, comprising an individual metal wire of diameter D1, the individual metal wire being coated in an elastomer composition and wound contiguously at least three times in an axial direction and at least twice in a radial direction.
