Abstract

Tire with gas distribution under pressure in several sealed volumes and single valve. The tire incorporates two or more sealed volumes (1 and 2), separated by insulating and flexible walls (3 and 4), and intended to contain one or more gases under pressure; in addition, it has independent ducts that communicate each sealed volume with a single valve (5) of gas inlet and outlet of the tire, the valve being common to all the sealed volumes, so that, in case of closing of the valve, all the ducts are plugged, and in case of opening of the valve, all the ducts communicate simultaneously with the external opening of the valve. This tire allows that in case of breakage of the surface surrounding one of the volumes, the loss of pressure to the affected volume is limited.

Description

Neumático con distribución de gases a presión en varios volúmenes estancos y válvula única. Tire with pressurized gas distribution in various sealed volumes and single valve.

Ámbito de la técnica Scope of the technique

La invención se encuadra dentro del sector de neumáticos destinados a cualquier tipo de vehículo. The invention falls within the sector of tires intended for any type of vehicle.

Estado de la técnica State of the art

Los sucesivos avances relativos a la seguridad en los neumáticos y ruedas utilizadas por todo tipo de vehículos han derivado en la existencia de dos sistemas diferenciados en función de la incorporación, o no, en su interior, de una cámara de aire independiente de la cubierta externa del neumático. De este modo, en automóviles, camiones y furgonetas, es habitual la utilización de neumáticos sin cámaras de aire, mientras en bicicletas o similares, es usual utilizar cubiertas que incorporan una cámara de aire independiente en su interior. En ambos casos, la elasticidad y flexibilidad de la rueda se consigue mediante la introducción de aire a presión en el interior de una cubierta o de una cámara estanca. Successive advances in tire and wheel safety used by all types of vehicles have led to the existence of two different systems depending on whether or not they incorporate an air chamber independent of the external cover. of the tire. Thus, in automobiles, trucks and vans, it is common to use tires without inner tubes, while in bicycles or the like, it is usual to use tires that incorporate a separate inner tube. In both cases, the elasticity and flexibility of the wheel is achieved by introducing pressurized air inside a cover or a sealed chamber.

En todos estos neumáticos, cuando, por algún motivo, se produce la ruptura o pinchazo de la superficie de la cubierta exterior, se suele producir una pérdida inmediata de la presión en el interior de la rueda. En el caso de cubiertas que no cuentan con cámaras de aire en su interior, al producirse una desgarradura en su superficie, el volumen interior de aire deja de ser estanco y se suele producir una fuga inmediata de aire hacia el exterior que se encuentra a una presión inferior. En el caso de cubiertas que cuentan con una cámara de aire en su interior, es frecuente que al producirse una desgarradura en la superficie exterior de la cubierta también se desgarre la superficie de la cámara de aire que se encuentra en contacto con la cubierta externa, en especial si ésta se produce por la acción de un objeto punzante. In all these tires, when, for some reason, the surface of the outer casing breaks or punctures, there is usually an immediate loss of pressure inside the wheel. In the case of roofs that do not have air chambers inside, when a tear occurs on its surface, the interior air volume is no longer watertight and there is usually an immediate air leak to the outside, which is at a lower pressure. In the case of covers that have an air chamber inside, it is frequent that when a tear occurs in the outer surface of the cover, the surface of the air chamber that is in contact with the external cover also tears. especially if it is produced by the action of a sharp object.

Es habitual que esta rotura accidental de la superficie que mantiene confinado el aire a presión se produzca durante la marcha del vehículo, produciéndose una pérdida It is usual that this accidental breakage of the surface that keeps the pressurized air confined occurs during the vehicle's running, causing a loss
