Embodiment Construction

[0089] Tire according to the first embodiment of the present invention

[0090] The figures show a frame of reference X, Y, Z corresponding respectively to the general axial direction (X), radial direction (Y) and circumferential direction (Z) of the tyre.

[0091] figure 1 A tire according to a first embodiment of the invention, in this case a pneumatic tire, is shown indicated generally at 10 . The tire 10 substantially exhibits a rotation about an axis substantially parallel to the axial direction X. The tire 10 here is intended for passenger cars.

[0092] The tire 10 is a radial tire and comprises a crown 12 with a tread 20 and a crown reinforcement 14 extending in the circumferential direction Z in the crown 12 . The crown reinforcement 14 comprises a working reinforcement 15 having a first working ply 16 and a second working ply 18 and a hooping reinforcement 17 having a hooping ply 19 . The crown reinforcement 14 is covered by a tread 20 . In this case, a hooping ...

Abstract

The invention relates to a tire comprising at least a first working ply and a second working ply (16, 18), said first and second working ply (16, 18) respectively comprising a first reinforcement elements and second reinforcing elements (50, 52), wherein at least one of the following relational expressions is satisfied: 4053x E1+4720<(D1 4 x d1x 1000) / E1 (I), 4053x E2+4720<(D2 4 x d2 x 1000) / E2 (II) where: D1, D2 is the diameter of each reinforcing element (50, 52) made of metal monofilaments (66, 68), D1 and / or D2 ranges from 0.34 to 0.38mm , d1, d2 are the densities of reinforcing elements (50, 52), d1, d2 are in units of monofilaments per decimeter, E1, E2 are the average thickness of the working ply (16, 18), E1, E2 are in mm unit.

Description

technical field [0001] The present invention relates to tires comprising an improved crown reinforcement. A tire is understood to mean a substantially annular structure. Preferably, the invention relates to pneumatic tyres. Pneumatic tires are understood to mean tires intended to form, in cooperation with a supporting element such as a rim, a cavity capable of being pressurized to a pressure higher than atmospheric pressure. In contrast, non-pneumatic tires cannot be pressurized. [0002] The invention relates to the field of tires intended to be adapted to rolling vehicles. The tire is preferably designed for passenger cars, but may be used on any other type of vehicle, such as two-wheeled vehicles, heavy vehicles, agricultural vehicles, construction vehicles or aircraft, or more generally, on any rolling gear. Background technique [0003] A first prior art described in WO2013117476 is known. WO2013117476 describes a radial pneumatic tire comprising a crown reinforcem...
