Pneumatic tire equipped with a transponder
A pneumatic tire includes: a body ply partially collapsed onto itself and therefore having two lateral flaps, in each of which an edge of the body ply rests against an intermediate portion of the body ply itself; two annular beads, each of which is surrounded by the body ply and comprises a bead core and a bead filler; an annular tread; a pair of sidewalls arranged axially externally to the body ply and extending radially inward from the tread; a pair of abrasion gum strips arranged at the beads axially externally to the body ply, and extending radially inward from the sidewalls; and a transponder axially arranged in an interior of one of the two flaps and located radially more to the inside of the edge of the body ply, wherein a radial distance greater than 7 mm is provided between the transponder and the edge of the body ply.
1 . A pneumatic tire comprising:
a toroidal carcass, which comprises a body ply partially collapsed onto itself and therefore having two lateral flaps, in each of which an edge of the body ply rests against an exterior intermediate portion of the body ply itself;
two annular beads, one on each axial side of the tire, each of which occupies the respective space that is surrounded by the body ply and comprises a bead core and a bead filler;
an annular tread;
a pair of sidewalls, one on each axial side of the tire, arranged axially externally to the body ply and extending radially inward from the tread;
a pair of abrasion gum strips, one on each axial side of the tire, arranged at the beads axially externally to the body ply, and extending radially inward from the sidewalls; and
a transponder which is axially arranged in an interior of one of the two flaps of the body ply and is located radially more to the inside of the edge of the body ply in the one of the two flaps of the body ply;
wherein the transponder is arranged in contact with the body ply at the one of the two flaps of the body ply and the transponder is arranged radially between the edge of the body ply in the one of the two flaps of the body ply and the bead surrounded by the part of the body ply including the edge of the body ply;
wherein a radial distance greater than 7 mm is provided between the transponder and the edge of the body ply in the one of the two flaps of the body ply.
2 . The pneumatic tire of claim 1 , wherein a radial distance of at least 10 mm at the point of minimum distance is provided between the transponder and the edge of the body ply in the one of the two flaps of the body ply.
3 . The pneumatic tire of claim 1 , wherein the transponder is arranged radially more to the outside of the bead surrounded by the part of the body ply including the edge of the body ply in the one of the two flaps of the body ply.
4 . The pneumatic tire of claim 1 , wherein the transponder is axially in contact on both sides with the body ply.
5 . The pneumatic tire of claim 1 , wherein the transponder is arranged axially more to the inside of the sidewall arranged axially externally to the one of the two flaps of the body ply and of the abrasion gum strip extending radially inward from the sidewall.
6 . The pneumatic tire of claim 5 , wherein the transponder is arranged in a zone wherein both the sidewall and the abrasion gum strip are present.
7 . The pneumatic tire of claim 1 , wherein the transponder is inserted within a sleeve made of two strips of rubber superimposed one onto the other.
8 . The pneumatic tire of claim 7 , wherein the two strips of rubber of the sleeve are 1-2 mm longer and wider than the transponder.
9 . The pneumatic tire of claim 7 , wherein the two strips of rubber conform to the shape of the components of the transponder.
10 . The pneumatic tire of claim 1 , wherein the transponder has a rectilinear form whose long sides are in the length direction and whose short sides are in the width direction and wherein the width direction extends outwardly in the tire radial direction.
