Adapter for a rolling assembly and rolling assembly comprising same

A flexible adapter for a rolling assembly, the rolling assembly comprising a tire having two beads, a rim and at least one adapter intended to ensure a radially flexible link between one of the beads and the rim, the rim having two rim seats, each rim seat being extended axially outwards by a rim flange, and the rim seat having a diameter D3,

• wherein a shape of the adapter is configured to have symmetry of revolution about an axis of rotation,
• wherein the adapter comprises:
• an axially inner end intended to be mounted on one of the rim seats and intended to be immobilized axially against an adjacent rim flange;
• an axially outer end;
• a body oriented mainly axially and disposed between the axially outer end and the axially inner end, the body having a radially outer face and a radially inner face, and the axially inner end having an axially outer face substantially at right angles to the axis of rotation;
• and
• an adapter seat intended to receive a tire bead, the adapter seat being defined by a base and a shoulder, the shoulder being formed essentially by an axially inner face of said axially outer end, said base being formed on the radially outer face of the body, at the axially outer end thereof, the intersection between the base and the shoulder forming a circle of diameter D1, the diameter D1 being called adapter seat diameter,
• wherein the difference d between the diameters D1 and D3 lies between 25.9 mm and 30.4 mm, and
• wherein the width measured between the shoulder of the axially outer end and the axially outer face of the axially inner end is between 35 and 45 mm.
