Embodiment Construction

[0066] figure 1 (Shows an adapter according to prior art) comprising a tire P (partially shown) and an adapter A and a rim J.

[0067] The tire (without changing the design for its part in the present invention) comprises a tread reinforced by a crown reinforcement connected by two sidewalls 1 to two tires on each side of the equatorial plane XX' Circle B. The carcass reinforcement 2 that mainly reinforces the sidewall 1 is anchored in each bead B at at least one bead wire (in this case of the "braided" type 3) so as to form a bead 4 separated from the main part of the carcass reinforcement by means of element 5 .

[0068] It is important to note that the invention can be implemented with various types of tires (radial or diagonal, or even types with self-supporting sidewalls).

[0069] The rim J comprises a groove 6 (known as a mounting groove) connecting on each side of the equatorial plane two rim wells 7 which extend axially through a rim 8 which The radially outer edg...

Abstract

The invention discloses an adapter for a rolling assembly and the rolling assembly comprising the same. The invention relates to an adapter for a rolling assembly having an axis of rotation and comprising a tyre having two beads and a rim, said adapter providing the connection between one of the rib beads and the rim, said rim having two rim seats (7), said adapter having an axially internal end (10) intended to be mounted on the seat of the rim and comprising an internal reinforcing element (16), an axially external end (9) intended to be mounted on the seat of the rim and comprising an external reinforcing element (15), a body (11) connecting said external end to said internal end in such a way as to form a single unit and comprising at least one main reinforcement providing the connection between said external reinforcement and said internal reinforcement, a substantially cylindrical adapter seat (18) intended to accept one of said beads, an adapter bearing face (21); substantially comprised in a plane perpendicular to the axis of rotation. The adapter is characterized in that the reinforcement of the axially external end is entirely outside the bearing face, and in that the body comprises, facing the adapter seat, a seat annular reinforcement that has a compression modulus of 1 GPa or more.

Description

technical field [0001] The invention relates to an adapter for a rolling assembly consisting essentially of a tire and a rim, and to a rolling assembly comprising said adapter. Background technique [0002] A reminder of the definitions used in the present invention is given below: [0003] - "axial direction" is a direction parallel to the axis of rotation of the tyre, [0004] - "radial direction" is a direction intersecting the axis of rotation of the tire and perpendicular thereto, [0005] - "circumferential direction" is a direction perpendicular to the radius and contained in a plane perpendicular to the axis of rotation of the tyre, [0006] - "radial section" is a section in a plane including the axis of rotation of the tyre, [0007] - "equatorial plane" is the plane perpendicular to the axis of rotation and passing through the middle of the tread. [0008] It is already known from application WO 00 / 78565 to insert elastic adapters between the rim and the beads...
