Problems solved by technology

[0007] Although the location of the communication module is generally favorable for radio frequency communication, it is limited in terms of UHF radio frequency performance (which is sensitive to metal), especially when the carcass ply is made of metal wires
However, even when the wire is non-metallic, embedding the communication module in the bead, while good for the durability of the tire and the physical integrity of the communication module, is detrimental to good RF communication performance

Embodiment Construction

[0039] Hereinafter, the terms "rubber compound", "rubber" and "compound" are used interchangeably to denote the rubber component of the tyre.

[0040] exist figure 1 The axial direction X, the circumferential direction C and the radial direction Z of the bead 34 of the tire according to the invention are shown in .

[0041] With respect to the axial direction, "axially outward" means the axial direction towards the outside of the tire, and "axially inward" means the axial direction towards the inner cavity of the tire.

[0042] A tire typically includes a crown, two sidewalls and two beads. exist figure 1 Only the radially inner portions of the sidewalls 32 and beads 34 are shown. figure 1 The bead 34 shown in includes a bead wire 35 exhibiting rotational symmetry and a first carcass ply 37 having a first portion 371 directed from the sidewall 32 toward The bead wire 35 extends and extends to form a bead 372 that wraps around the bead wire 35 and extends radially on the outs...

Abstract

The invention relates to a tyre provided with a radio frequency communication module (2), said tyre having a carcass reinforcement comprising two carcass plies (37, 38), such that the communication module (2) is arranged in the bead (34) axially on the outside and against the second carcass ply (38).

Description

technical field [0001] The present invention relates to tyres, and more particularly to tires equipped with radio frequency communication modules. Background technique [0002] More particularly, but not exclusively, the invention applies to a tire intended for a motor vehicle of the passenger vehicle type being a high-power high-speed vehicle. Such tires generally comprise a carcass reinforcement having more than one (for example two) carcass plies with threads made of non-metallic material, such as rayon, nylon or polyester silk. [0003] The axial, radial and circumferential directions of the tire are defined with respect to the axis of rotation of the tire. [0004] In the prior art (for example EP 2186658A1 ), tires comprising radio frequency communication modules are known. In this document, the radio frequency communication module comprises a passive radio frequency identification transponder equipped with two antennas forming a dipole. Transponders of this type a...
