Abstract

An adapter, for a rolling assembly having an axis of rotation and comprising a tyre (P) having two beads (B), and a rim (J), provides the connection between one of the beads (B) and the rim (J), the said rim having two rim seats (7), the said adapter having an axially inner end (10) intended to be mounted on the rim seat (7) and comprising an inner reinforcing element (16), the said reinforcing element (16) having a centre C2, an axially outer end (9) comprising an outer reinforcing element (15), the said reinforcing element (15) having a centre C1, a body (11) that connects the said outer end (9) to the said inner end (10) so as to form a single piece and comprises at least one main reinforcement that provides the connection between the said outer reinforcer and the said inner reinforcer, and comprises a first end (17A) and a second end (17B), a substantially cylindrical adapter seat (18) intended to receive one of the said beads (B), the said seat (18) being situated at the axially outer end (9) of the said body (11), an adapter bearing face (21) substantially contained in a plane perpendicular to the axis of rotation, the said bearing face being situated on the axially inner face of the axially outer end (9), and an overall length L and a length LT measured between the centres C1 and C2. The first end (17A) and the second end (17B) of the reinforcement are arranged one upon the other so as to form an overlap.

First claim

The invention claimed is:

1. An adapter for a rolling assembly having an axis of rotation and comprising a tire having two beads and a rim, the adapter providing the connection between one of the beads and the rim, the rim having two rim seats, and the adapter having:
an axially inner end intended to be mounted on a rim seat and comprising an inner reinforcing element, the inner reinforcing element having a center C 2 ;
an axially outer end comprising an outer reinforcing element, the outer reinforcing element having a center C 1 ;
a body that connects the axially outer end to the axially inner end so as to form a single piece and comprises at least one main reinforcement that provides the connection between the outer reinforcing element and the inner reinforcing element, and comprises a first end and a second end, wherein the at least one main reinforcement is attached axially on an inside and radially on an outside to a wall of the outer reinforcing element, and anchored to the inner reinforcing element, so as to form an upturn at both the axially inner end and the axially outer end of the adapter;
a substantially cylindrical adapter seat intended to receive one of the beads, the seat being situated at the axially outer end of the body;
an adapter bearing face substantially contained in a plane perpendicular to the axis of rotation, the adapter bearing face being situated on an axially inner face of the axially outer end; and
an overall length L and a length LT measured between the centers C 1 and C 2 ,
wherein the first end and the second end of the at least one main reinforcement are arranged one upon the other so as to form an overlap to ensure coupling between superposed ply portions of the at least one main reinforcement.

2. The adapter according to claim 1 , wherein the overlap has a length l greater than or equal to 0.2L and less than or equal to 0.5L.

3. The adapter according to claim 1 , wherein the overlap has a length l less than or equal to 0.6LT.

4. The adapter according to claim 1 , wherein the at least one main reinforcement comprises a ply comprising reinforcers coated in an elastomer composition, the reinforcers being mutually parallel and making an angle comprised between 0° and 90° with the circumferential direction.

5. A rolling assembly having an axis of rotation and comprising a tire having two beads, a rim, and an adapter providing the connection between one of the beads and the rim, the rim having two rim seats, and the adapter having:
an axially inner end intended to be mounted on a rim seat and comprising an inner reinforcing element, the inner reinforcing element having a center C 2 ;
an axially outer end comprising an outer reinforcing element, the outer reinforcing element having a center C 1 ;
a body that connects the axially outer end to the axially inner end so as to form a single piece and comprises at least one main reinforcement that provides the connection between the outer reinforcing element and the inner reinforcing element, and comprises a first end and a second end, wherein the at least one main reinforcement is attached axially on an inside and radially on an outside to a wall of the outer reinforcing element, and anchored to the inner reinforcing element, so as to form an upturn at both the axially inner end and the axially outer end of the adapter;
a substantially cylindrical adapter seat intended to receive one of the beads, the seat being situated at the axially outer end of the body;
an adapter bearing face substantially contained in a plane perpendicular to the axis of rotation, the adapter bearing face being situated on an axially inner face of the axially outer end; and
an overall length L and a length LT measured between the centers C 1 and C 2 ,
wherein the first end and the second end of the at least one main reinforcement are arranged one upon the other so as to form an overlap to ensure coupling between superposed ply portions of the at least one main reinforcement.

6. The rolling assembly according to claim 5 , wherein the overlap has a length l greater than or equal to 0.2L and less than or equal to 0.5L.

7. The rolling assembly according to claim 5 , wherein the overlap has a length l less than or equal to 0.6LT.

8. The rolling assembly according to claim 5 , wherein the at least one main reinforcement comprises a ply comprising reinforcers coated in an elastomer composition, the reinforcers being mutually parallel and making an angle comprised between 0° and 90° with the circumferential direction.
