Embodiment Construction

[0041] figure 1 Shows a half-sectional view of the crown of a prior art aircraft tire 1 comprising a tread 2 intended to come into contact with the ground and radially Protective reinforcement 3 inside the tread 2 . The protective reinforcement 3 is a cylindrical structure having as its axis of revolution the axis of rotation YY' of the tire, radially extending from the first The axial end E1 extends to a second axial end E2 and extends radially with an average radial thickness T from the radially inner first surface 31 to the radially outer second surface 32 . The protective reinforcement 3 comprises a reinforcement 4 coated with an elastomeric compound, having a diameter D and having a path in the circumferential direction XX' of the tyre. The protective reinforcement 3 is located radially outside the working reinforcement 5, which in this case comprises four working layers overlapping radially and consisting of a reinforcement 6, said The reinforcement 6 has a zigzag pa...

Abstract

The present invention relates to an aeroplane tyre and, in particular, to its protective reinforcement, and has the objective of increasing its resistance to perforation and cutting by foreign objects. According to the invention, the protective reinforcement (3) has a mean radial thickness T at least equal to 2 times the diameter D of a reinforcer (4), the protective reinforcement (3) comprises, on its radially inner face (31) and on its radially outer face (32), respectively, parts made of an elastomer compound (7) having an axial width W at least equal to the diameter D of a reinforcer (4), and the trajectory of any reinforcer (4) of the protective reinforcement (3), in the circumferential direction (XX') of the tyre, varies radially between the first radially inner face (31) and the second radially outer face (32), such that the trajectories of the reinforcers (4) of the protective reinforcement (3) together form a three-dimensional lattice.

Description

technical field [0001] The present invention relates to aircraft tyres, and in particular to protective reinforcements for aircraft tyres. Background technique [0002] Typically, the geometry of a tire is usually described in a meridional or radial plane including the axis of rotation of the tyre, since it exhibits rotational symmetry with respect to the axis of rotation. For a given meridian plane, radial, axial and circumferential directions denote directions perpendicular to the axis of rotation of the tire, parallel to the axis of rotation of the tire and perpendicular to the meridian plane, respectively. [0003] Hereinafter, the expressions "in the radial direction", "in the axial direction" and "in the circumferential direction" respectively mean "in the radial direction of the tire", "in the axial direction of the tire" and "in the circumferential direction of the tire direction". The expression "radially inwardly located and radially externally located" respectiv...
