Abstract

A tire for a handling vehicle, designed to transport heavy loads, over short distances and at low speeds, and a mounted assembly consisting of a tire mounted on a rim. Also, a method for producing such a mounted assembly. A mounted assembly includes a tire mounted on a rim, having a tread designed to come into contact with a ground, two sidewalls extending radially inwards from the ends of the tread, and two beads extending the sidewalls radially inwards and in contact with the rim, an internal cavity containing a filling component consisting of at least one incompressible solid element, and which is a granular filling component consisting of granules at least partly separated from one another by interstices containing at least gas, and the fill rate, which is the ratio between the total volume of the granules, the total of the elementary volumes of the granules, and the volume of the internal cavity, is at least equal to 0.8.

Claims

1. A method for producing a mounted assembly, the mounted assembly comprising:

a tire mounted on a rim, the tire comprising a tread designed to come into contact with a ground, two sidewalls extending radially inwards from the ends of the tread, and two beads extending the sidewalls radially inwards and in contact with the rim,

the tread, the two sidewalls, the two beads and the rim delimiting an internal cavity, the internal cavity containing a filling component comprising at least one incompressible solid element,

wherein the filling component is a granular filling component consisting of granules at least partly separated from one another by interstices containing at least one gas,

the fill rate, which is the ratio between the total volume of the granules, the total of the elementary volumes of the granules, and the volume of the internal cavity, is at least equal to 0.8, and the method comprises the following steps;

a) installing a cylindrical shroud with a diameter equal to the diameter of the rim, so as to close off the internal cavity of the tire, filling the internal cavity of the tire with the granular filling component with the aid of a filling means, and compacting the granules, so as to obtain the intended fill rate and to form an intermediate assembly comprising the tire, filled with the granular filling component, and the shroud;

b) installing the intermediate assembly on a transfer frame comprising a transfer means and the rim onto which the tire, filled with the granular filling component, is to be mounted; and

c) transferring the tire, filled with the granular filling component, from the shroud onto the rim, by application of a force parallel to the axis of revolution of the tire by the transfer means, so as to form the mounted assembly.
