Electronic assembly for installation in a tyre
View Patent ↗An electronic assembly, which is intended for installation in a tire, includes an electronic device and a transition layer. The electronic device includes an electronic member and at least one antenna fixed to a support of the electronic member. Each antenna includes a free part, which is free with respect to the support, joined to a fixing part, which fixes the antenna to the support. The transition layer is formed of a composition that includes 9 to 13 parts of sulfur per hundred parts by weight of elastomer. The transition layer coats at least a junction between the free part and the fixing part of each antenna.
1. An electronic assembly for installation in a tire, the assembly comprising:
an electronic device that includes:
an electronic member including a support, and
at least one antenna fixed to the support, each antenna of the at least one antenna including a free part, which is free with respect to the support, joined to a fixing part, which fixes the antenna to the support; and
a transition layer formed of at least a composition that includes:
an elastomer, and
9 to 13 parts of sulfur per hundred parts by weight of the elastomer,
wherein the transition layer coats at least a junction between the free part and the fixing part of each antenna of the at least one antenna.
2. The electronic assembly according to claim 1 , wherein the composition includes a resin.
3. The assembly according to claim 1 , wherein the composition includes 3 to 14 parts of oil per hundred parts by weight of the elastomer.
4. The assembly according to claim 1 , wherein the transition layer is formed of the composition.
5. The assembly according to claim 1 , wherein the transition layer covers an entirety of each of the at least one antenna.
6. The assembly according to claim 1 , further comprising an adhesion layer interposed between the electronic device and the transition layer.
7. The assembly according to claim 1 , wherein an average thickness of the transition layer is in a range of from 1 mm to 1.5 mm.
8. The assembly according to claim 7 , wherein the average thickness of the transition layer is in a range of from 1 mm to 1.2 mm.
9. The assembly according to claim 1 , wherein the assembly is separate from the tire and separate from a green tire blank.
10. The assembly according to claim 1 , wherein the assembly is incorporated in a green tire blank.
11. A tire comprising:
an electronic device that includes:
an electronic member including a support, and
at least one antenna fixed to the support, each antenna of the at least one antenna including a free part, which is free with respect to the support, joined to a fixing part, which fixes the antenna to the support; and
a transition layer coating at least a junction between the free part and the fixing part of each antenna, the transition layer having a gradient in a sulfur content thereof.
