Abstract
A tire with reduced rolling noise includes a tire structure formed of at least one crown extended by two sidewalls and two beads. A base of each of the two beads is configured to be mounted onto a rim seat. The tire also includes a carcass-type reinforcing structure anchored into the two beads and an additional layer bonded to an inner wall of the tire structure. The additional layer is bonded to the tire structure at its edges and the rest of the additional layer is not bonded. The additional layer includes an inflation valve.
Claims23
A tire comprising:
- a tire structure formed of at least one crown extended by two sidewalls and two beads, wherein a base of each of the two beads is configured to be mounted onto a rim seat;
- a carcass-type reinforcing structure anchored into the two beads;
- and
- an additional layer bonded to an inner wall of the tire structure,
- wherein the additional layer is bonded to the tire structure at edges of the additional layer and the additional layer is not bonded to the tire structure elsewhere,
- wherein a length of the additional layer is greater than a length of an opening between the two beads,
- wherein the additional layer in conjunction with the inner wall of the tire structure forms an airtight cavity,
- wherein the additional layer includes an inflation valve,
- wherein, when the airtight cavity is inflated for operation, via the inflation valve, the additional layer is pushed towards a rim wall at the opening between the two beads and away from the inner wall of the tire structure, and folds are formed in the additional layer, and
- wherein the additional layer includes a first layer made of a cellular material and a second layer made of a non-cellular material.
