Problems solved by technology

[0014] However, the above-mentioned positioning of the transponder within the pneumatic tire is not ideal, because they do not minimize the stress and deformation to which the transponder is subjected (both during the construction of the pneumatic tire and during the use of the pneumatic tire), and at the same time do not allow the transponder to minimize RF communication interference and interference

Embodiment Construction

[0025] exist figure 1 , a pneumatic tire is generally indicated by the numeral 1 and comprises an annular carcass 2 comprising a single carcass ply 3 partially folded onto itself, thus having two lateral flaps (i.e. The two layers are stacked on top of each other and are collectively referred to as a "foldback"). In each flap of the carcass ply 3 , the edges (ie ends) of the carcass ply 3 bear against the middle portion of the carcass ply itself. In other words, the endless carcass 2 includes only and uniquely a single and unique carcass ply 3, and thus does not include any other carcass ply (whether forming folds or not) superimposed on the carcass ply 3. wing).

[0026] On opposite sides of the carcass 2, two annular beads 4 are arranged, each bead surrounded by the carcass ply 3 (ie by the flaps of the carcass ply 3) and having a bead core 5 And the bead filler 6, the bead core 5 is reinforced with a number of windings of metal wires.

[0027] A carcass 2 supports an an...

Abstract

A pneumatic tire (1) having: a toroidal carcass (2), which is comprised of a body ply (3) partially collapsed onto itself and therefore having two lateral flaps; two annular beads (4), each of which is surrounded by the body ply (3) and has a bead core (5) and a bead filler (6); an annular tread (7); a pair of sidewalls (11) arranged externally to the body ply (3) between the tread (7) and the beads (4); a pair of abrasion gum strips (12) arranged externally to the body ply (3) under the sidewalls (13) and at the beads (4); and a transponder (13) which is arranged in contact with the body ply(3) at a flap of the body ply (3) and is located below an edge (19) of the body ply (3) between the edge (19) of the body ply (3) and the bead (4).

Description

technical field [0001] The present invention relates to a pneumatic tire equipped with a transponder. Background technique [0002] In recent years, so-called "smart" pneumatic tires have emerged, capable of forming an important part of modern vehicles, providing information about the type of pneumatic tire installed, information about the state of the pneumatic tire and information about environmental conditions. [0003] "Smart" pneumatic tires are often equipped with transponders (i.e., electronics adapted to communicate via radio frequency) that allow remote communication of the tire's identity, characteristics, and communication, but also with the operator who must perform the inspection or replacement of the pneumatic tire). [0004] Recently, based on the presence of transponders, the unification of RFID ("Radio Frequency Identification") technology and TPMS ("Tire Pressure Monitoring System") technology has been proposed, which measures the effective inflation press...
