摘要:
A tire comprising at least one carcass-type reinforcing structure and comprising a crown reinforcing structure having at least one working layer. At least one working layer is radially on the inside of at least one carcass layer, in the sidewalls, the tire comprises at least two carcass reinforcing layer portions extending over a radial distance at least equal to 50% of the radial distance between an end of a shoulder and the radially inner end of the radially innermost circumferential reinforcing element, at least in the equatorial plane, the reinforcing elements of the carcass reinforcement make an angle less than 80°, and the reinforcing elements of the working layer cross with the reinforcing elements of the carcass-type reinforcing structure by an angle greater than 40°, when the tire comprises at least two working layers radially on the inside of at least one carcass layer, the reinforcing elements of the at least two working layers being crossed by an angle of at most 5° and when the tire comprises at least one working layer radially on the outside of the carcass-type reinforcing structure, the reinforcing elements of the at least one working layer crossing with the reinforcing elements of at least one working layer radially on the inside of at least one carcass layer by an angle of at least 30°.
摘要:
A tire comprising at least one carcass-type reinforcing structure formed of at least one layer of mutually parallel reinforcing elements making an angle, with the circumferential direction, of strictly less than 75° at least in the region of maximum axial width of the tire and of strictly less than 65° at least in the equatorial plane anchored on each side of the tire to a bead, each bead extending radially outwards in the form of a sidewall, the sidewalls radially towards the outside meeting a tread, and comprising, under the tread, a crown reinforcing structure consisting of at least one layer of reinforcing elements making angles of between 10° and 60° with the circumferential direction and known as a working layer, radially on the outside of the carcass-type reinforcing structure. In sidewalls, the tire comprises at least two axially adjacent carcass reinforcing layer portions, the reinforcing elements of the said carcass reinforcing layer portions being directed on each side of a meridian plane, at least in part of the sidewalls, and the reinforcing elements of at least one working layer crossing the reinforcing elements of the carcass-type reinforcing structure at an angle greater than 40°.

摘要:
A method for simplifying the conventional pressure monitoring and/or adjustment method for a mounted assembly for a vehicle, in particular for a two-wheeled vehicle, and, more precisely, reducing the number of steps in the method, and a pressure monitoring and/or adjustment device for the use of this method. A mounted assembly (31) is composed of a tire (32), preferably tubeless, mounted on a rim (33) and inflated to an initial pressure, the tire comprising an inner surface forming the wall (34) of the tire cavity, in contact with the internal air, the wall of the tire cavity being at least partially covered with a self-sealing material (35). An inflation interface (36) is introduced into the tire cavity by piercing a hole in the wall of the tire cavity in an area covered by the self-sealing material, the inflation interface is extracted from the tire cavity after inflation, and the pierced hole in the wall of the tire cavity is sealed spontaneously by the self-sealing material, after the extraction of the inflation interface.
摘要:
A tire for a motorized two wheeled vehicle comprising a reinforcing structure of the carcass type, made up of reinforcing elements, anchored on each side of the tire to a bead the base of which is intended to be mounted on a rim seat, each bead being extended radially outwards by a sidewall, the sidewalls radially towards the outside joining to a tread. The tread comprises at least one incision and in a circumferential plane, at least part of one wall of the at least one incision forms with the radial direction an angle of between 5 and 45°, and the angle formed between at least one part of one wall of the at least one incision and the radial direction in a first circumferential plane is different from the angle formed between at least one part of one wall of the at least one incision and the radial direction in at least one second circumferential plane.
摘要:
A tire with reduced rolling noise includes a tire structure formed of at least one crown extended by two sidewalls and two beads. A base of each of the two beads is configured to be mounted onto a rim seat. The tire also includes a carcass-type reinforcing structure anchored into the two beads and an additional layer bonded to an inner wall of the tire structure. The additional layer is bonded to the tire structure at its edges and the rest of the additional layer is not bonded. The additional layer includes an inflation valve.
