Adapter for a wheel assembly and a wheel assembly comprising same

Abstract

The invention relates to an adapter for a wheel assembly having a rotational axis and comprising a tire (P) with two beads (B), a wheel rim (J), where said adapter forms the junction between one of the beads and the wheel rim, where said wheel rim has two wheel-rim seats (20) and two wheel-rim hooks (12), where said adapter has an axially inner end (2) intended to be mounted on the wheel-rim seat and comprising an inner reinforcement element (5), an axially outer end (1) intended to be mounted on the wheel-rim seat and comprising an outer reinforcement element (4), a body (3) connecting said outer end (1) to said inner end (2) such as to form a single part comprising at least one main reinforcement frame that ensures the connection between said outer reinforcement element (4) and said inner reinforcement element (5), a substantially cylindrical adapter seat (7) intended to receive one of said beads, an adapter bearing surface (8) substantially in a plane perpendicular to the axis. This adapter is characterized in that the reinforcement element (4) of the axially outer end is entirely located axially outside the bearing surface (8), and in that the body (3) comprises a ring-shaped seat protuberance (9) opposite the adapter seat (7), where said protuberance (9) comprises at least one rubber composition.

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. The invention relates more particularly to tires for passenger vehicles and heavy vehicles. 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 containing 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] A "rubber composition...

AI Technical Summary

Problems solved by technology

[0010] In various conceived solutions, it is possible to increase the resistance to shedding by bonding the tire to the mounting rim, but this solution has the disadvantage of making it very difficult to remove the tire

[0013] However, this adapter also comprises, as connecting element, a composite constituent part of the reinforcing cord type, comprising an elastic composition and a textile reinforcement, and which does not allow accurate radial deformation of the mounted assembly
