Abstract

An adapter for a rolling assembly having an axis of rotation (YY′) includes an axially inner end connected to a rim, an axially outer end including an outer reinforcing element and intended to come into contact, via a substantially radial axially inner face, or bearing face, with a bead, a body connecting the axially outer end to the axially inner end so as to form a single piece, including at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and including a substantially axial adapter seat intended to come into contact with a bead. The outer reinforcing element ( 15 ) is completely axially on the outside of the bearing face ( 21 ), and the outer reinforcing element ( 15 ) is a substantially annular structure, referred to as a bead wire, of substantially polygonal section, including 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 arranged mutually parallel and in alternation with each other and parallel to the axis YY′.

First claim

The invention claimed is:

1. 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.

2. The adapter according to claim 1 , wherein the rubber compound has a secant modulus greater than or equal to 10 MPa and less than or equal to 100 MPa.

3. The adapter according to claim 1 , wherein the rubber compound has an elastic elongation greater than or equal to 50%.

4. The adapter according to claim 1 , wherein the composite and/or metallic material has a Young's modulus greater than or equal to 40 GPa and less than or equal to 200 GPa.

5. The adapter according to claim 1 , wherein the rubber compound is selected from a diene and polyurethane compositions.

6. A rolling assembly comprising the adapter according to claim 1 .
