Carcass Reinforcement For An Aircraft Tire

摘要

Aircraft tire comprises carcass reinforcement (5) comprising a first family of carcass layers extending between two beads (3), having at least one carcass layer wrapped, within each bead, from the inside towards the outside of the tire, around a bead wire (6) to form turn-up (511) having free end (E1) radially outside of radially outermost point (E) of the bead wire. The second family comprises at least two carcass layers, adjacent each to the next, extending, within each bead, from outside towards inside of the tire, as far as their respective ends (E2) which are radially inside of axial straight line (DY) through centre (O) of bead wire (6) and axially inside of a radial straight line (DZ) through centre (O) at axial distance (d2) at least equal to 5 mm. The carcass layers of the second family are axially inside of at least one turn-up of a carcass layer of the first family.

主权项

1. An aeroplane tire comprising:
a tread connected by two side walls to two beads, which are configured to provide a mechanical connection between the tire and a rim; a crown reinforcement, radially on the inside of the tread, and a carcass reinforcement radially on the inside of the crown reinforcement; the carcass reinforcement comprising a first and a second family of carcass layers extending between the two beads; the first family comprising at least one carcass layer wrapped, within each said bead, from the inside towards the outside of the tire, around a circumferential reinforcing element known as a bead wire to form a turn-up having a free end radially on the outside of the radially outermost point of the bead wire; and, the second family comprising at least two carcass layers, adjacent each to the next, extending, within each said bead, from the outside towards the inside of the tire, as far as their respective ends which are radially on the inside of an axial straight line passing through the centre of the bead wire and axially on the inside of a radial straight line passing through the centre of the bead wire at an axial distance at least equal to 5 mm, wherein the carcass layers of the second family are axially on the inside of at least one turn-up of a carcass layer of the first family.
