Adapter for a rolling assembly and rolling assembly comprising same

An adapter for a rolling assembly having an axial axis, the rolling assembly comprising a tire having two beads, and a wheel rim having two wheel rim bead seats, where, for each bead, the adapter provides the connection between the bead and the wheel rim, the adapter comprising:

• an axially inner end comprising an inner reinforcing element connected to the wheel rim;
• an axially outer end comprising an outer reinforcing element comprising a substantially radial axially inner face intended to come into contact with the bead;
• 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, the axially outer end and the axially inner end and the body being arranged along the axial axis,
• wherein the outer reinforcing element is completely axially on the outside of the substantially radial axially inner face of the axially outer end,
• wherein the outer reinforcing element is a substantially annular structure having a mean diameter between 8 mm and 16 mm, comprising at least two first layers of composite and/or metallic material, and at least two second layers of rubber compound, the first and second layers being uninterrupted layers arranged mutually parallel and in alternation with each other and parallel to the axial axis, and
• wherein a thickness of each of the at least two first layers is greater than a thickness of each of the at least two second layers, the thickness being measured at a widest portion of each of the first and second layers, respectively.
