CROWN FOR AEROPLANE TIRE

摘要

An aeroplane tire comprising a tread, a crown reinforcement radially on the inside of the tread and comprising at least one crown layer, the radially interior crown layer having an axial width (L2) at least equal to two-thirds of the maximum axial width (L1) of the tire and comprising a concave portion of which the axial limits (M2, M′2), on either side of the equatorial plane (XZ), are the radially exterior points of the said crown layer, carcass reinforcement radially on the inside of the crown reinforcement and comprising at least one carcass layer, the radially exterior carcass layer comprising a concave portion of which the axial limits (M3, M′3), on either side of the equatorial plane (XZ), are the radially exterior points of the said carcass layer. The radial distance (d) between the respective concave portions of the radially interior crown layer and of the radially exterior carcass layer is at a maximum in the equatorial plane (XZ) and decreases continuously from the equatorial plane (XZ) as far as the axial limits (M2, M′2) of the said concave portions axially closest to the equatorial plane (XZ), where it reaches a minimum value (dM).

1. An aeroplane tire comprising:
a tread, a crown reinforcement radially on the inside of the tread and comprising at least one crown layer, the radially interior crown layer having an axial width (L2) at least equal to two-thirds of the maximum axial width (L1) of the tire and comprising a concave portion of which the axial limits (M2, M′2), on either side of the equatorial plane, are the radially exterior points of the said crown layer, a carcass reinforcement radially on the inside of the crown reinforcement and comprising at least one carcass layer, the radially exterior carcass layer comprising a concave portion of which the axial limits (M3, M′3), on either side of the equatorial plane, are the radially exterior points of the carcass layer, wherein the radial distance (d) between the respective concave portions of the radially interior crown layer and of the radially exterior carcass layer is at a maximum in the equatorial plane and decreases continuously from the equatorial plane as far as the axial limits (M2, M′2) of the said concave portions axially closest to the equatorial plane, where it reaches a minimum value (dM).
