摘要： Tyre comprising a hooping reinforcement (100), which reduces the tire noise emission, wherein the axial distance between neighbouring portions of the hooping reinforcement is greater than or equal to 0.7 mm and smaller than or equal to 2mm, with the exception of one first axial region Ll and two second axial regions L2. The axial distance of each of the axial ends of the first axial region Ll from the median plane is greater than or equal to 0.05-S and smaller than or equal to 0.15-S, S being the maximum axial width of the tyre. The two regions L2 are provided on both sides of the median plane, each second axial region being centred at an axial distance D2 from the median plane, D2 being greater than or equal to 0.25-S and smaller than or equal to 0.4-S. Each second axial region L2 has an axial width W2 that is greater than or equal to 0.1 -S. The sum of the axial widths of the first and second axial regions is smaller than or equal to 0.5-S. The difference between the average axial distance between neighbouring portions of the hooping reinforcement in the first and second axial regions Ll and L2, and the distance outside the first and second axial regions Ll and L2 is at least 0.2 mm. tyre having a belt ply with cords disposed along the circumference of the tire to reduce the tire noise

摘要： A tire (10) for driving on ice, comprising: a tread (20) having a rolling surface configured to come into contact with the ground when the tire is rolling along, and two lateral faces (27), this tread comprising at least one groove (25, 26) in the rolling surface; at least one stud (30) having a longitudinal axis (33), a part (31) of the stud projecting from the rolling surface, the intersection between the stud and the plane tangential to the portion of the rolling surface around the stud forming a contour C, that part of the stud that projects from the rolling surface having a minimum cross section Sm, Sm corresponding to the smallest cross section of the said part in any plane containing the radial direction that passes through the point of intersection between the longitudinal axis of the stud and the plane tangential to the portion of the rolling surface around the stud; at least one conduit (200-205) that forms, on the rolling surface of the tire, at least two opposing edges (211, 221; 212, 222; 213, 223), the minimum distance D between the conduit and the contour C being less than or equal to 1 cm, the conduit opening into the groove and/or onto a lateral face of the tread; wherein, for each stud, the sum of the mean cross sections Sn of the conduits, each mean cross section Sn being measured at right angles to one of the opposing edges formed by the conduit, is greater than or equal to half the minimum cross section Sm of that part of the stud that projects from the tread.

摘要： A vehicle wheel comprising a tyre which can be inflated to a pressure for supporting a load which is applied to it by the vehicle once said tyre is bearing on a running surface, on a rim ring (14) on which said tyre (12) can be mounted, said rim ring being able to bend elastically under forces having a radial component and being attached to a support ring (16) by connecting elements (20) which have a greater tensile strength than compressive strength and are able to deform by bending under the effect of loads corresponding substantially to forces encountered when the vehicle is running under standard conditions, the support ring (16) having a greater rigidity than the rim ring (14).

摘要： A calibration method for a differential resonator-type SAW sensor integrated in a set, the sensor having two resonating frequencies which evolve differently depending on the value of a physical unit of the set, the method comprising the following steps: A) Establishing a mean calibration function linking the differential frequency and the physical magnitude, wherein the mean calibration function is obtained by averaging on a plurality of sensors of the same type; B) Determining the differential frequency of the sensor when the physical magnitude corresponds to a predetermined value; C) Determining the deviation of the sensor relative to the mean calibration function; D) Determine the value of the physical magnitude corresponding to the measured differential frequency while taking the deviation into account.
