Embodiment Construction

[0060] Hereinafter, the terms "tyre" and "pneumatic tire" are used in an equivalent manner and refer to any type of pneumatic or non-pneumatic tire.

[0061] figure 1 A section of a pneumatic tire 1 according to the invention comprising a crown S extending through two sidewalls F and ending in two beads B is shown. In this embodiment, the tire 1 is intended to be mounted at the two beads B on a vehicle wheel 8 (not shown in this figure) of the heavy vehicle or construction equipment type. A closed cavity C is thus defined, containing at least one fluid under pressure and delimited by the inner surface 13 of the pneumatic tire 1 and the outer surface of the wheel 8 of the vehicle.

[0062] A reference axis 201 corresponding to the natural axis of rotation of the pneumatic tyre, and a midplane 211 perpendicular to the reference axis 201 and equidistant from the two beads are marked. The intersection of reference axis 201 and midplane 211 defines pneumatic tire center 200 . A ...

Abstract

The invention relates to a tire (1) equipped with a passive transponder (150) comprising at least one radiating antenna (151) embedded in an electrically insulating elastic body mixture to form a patch (100), said passive transponder (150) is able to communicate with a radio frequency reader placed on the outside of the tire (1). The patch (100) extends axially between the axially inner end of the carcass ply (3) and the inner surface (13) of the tire (1) and extends radially a distance between the bead toes ( 7) and the distance between the bead radially outer end (12).

Description

technical field [0001] The present invention relates to a pneumatic tire for heavy vehicles or construction equipment provided with identification and communication means, and to a communication method for such items. Background technique [0002] In the field of identification and communication devices, especially for tires, RFID (acronym for Radio Frequency Identification) passive radio frequency transponders are traditionally used. By simplifying the identification, monitoring and management of items, these devices can make the automated management of items more reliable and faster. Some devices provided with advanced functions are also able to obtain physical quantities of the items (in the case of tyres, such as temperature or inflation pressure) to ensure the correct use of these items during their lifetime. In the following, all these devices will be referred to by the generic term "passive communication electronics" or "passive transponder". [0003] These passive ...
