Abstract
The invention is intended specifically for semitrailers formed by a tractor unit (1) and a wheeled container (2) and for use when the pressure inside the air tank of the wheeled container is not sufficient for the nominal inflation pressure of the tyres (4) to be reached. The invention dispenses with the use of the traditional back-up pump, thereby providing the resulting cost-savings, and does not require the use of any other ancillary component in the vehicle. For this purpose, the system uses the air tank (5) of the tractor unit (1) and, in order for the tractor unit to remain physically independent of the wheeled container (2), said air tank (5) is provided with a take-off (6) extended in the form of a resiliently deformable spiral tube (7) terminating in a quick-action connector (8) corresponding to another connector (9) provided on the front wall of the wheeled container. In this way, the connectors (8, 9) allow easy pneumatic connection/disconnection of the tractor unit (1) and the wheeled container (2) whenever these parts are coupled and uncoupled in relation to one another.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un sistema de inflado, especialmente concebido para vehículos con gran capacidad de carga, en particular para semi-remolques, es decir vehículos estructurados mediante una cabeza tractora y un contenedor rodante, cuya finalidad es reponer la presión de aire en cualquiera de los neumáticos del vehículo ante un pinchazo o ante cualquier otro supuesto práctico que haga que la presión de dichos neumáticos se sitúe bajo un determinado nivel pre-establecido.The present invention relates to an inflation system, especially designed for vehicles with high load capacity, in particular for semi-trailers, that is to say vehicles structured by a tractor unit and a rolling container, whose purpose is to replenish the air pressure in any of the tires of the vehicle before a puncture or any other practical assumption that causes the pressure of said tires to be under a certain pre-established level.
El objeto de la invención es conseguir en el contenedor rodante la presión necesaria para que sus neumáticos alcancen a su vez la presión de trabajo pre-establecida para los mismos, y ello de una manera simple, económica y eficaz.The object of the invention is to obtain in the rolling container the necessary pressure so that its tires reach in turn the pre-established working pressure for them, and this in a simple, economical and efficient way.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Son conocidos sistemas de inflado automático para ruedas de
vehículos, tales como camiones y similares, consistentes en establecer una comunicación controlada entre el compresor del camión y las ruedas del vehículo, a través de un circuito en el que se establecen medios reguladores de presión, de manera que cuando la presión baja en uno de los neumáticos, por un pinchazo o por cualquier otra causa, una válvula permite el acceso de aire al sistema neumático de las ruedas, reponiendo en las mismas la presión teórica prevista para ellas.Automatic inflation systems for wheels of vehicles, such as trucks and the like, consisting of establishing a controlled communication between the compressor of the truck and the wheels of the vehicle, through a circuit in which pressure regulating means are established, so that when the pressure drops in one of the tires, by a puncture or for any other cause, a valve allows air access to the pneumatic system of the wheels, replenishing the theoretical pressure provided for them.
En el ámbito específico de la aplicación práctica de la invención, el de los semi-remolques, se plantea un problema técnico consistente en que, en muchas ocasiones, la presión que es capaz de suministrar el compresor del contenedor rodante, es insuficiente para alcanzar el nivel de presión exigido por los neumáticos que calza el vehículo.In the specific field of the practical application of the invention, that of semi-trailers, a technical problem arises in that, in many cases, the pressure that the compressor of the rolling container is able to supply is insufficient to reach the pressure level required by the tires that the vehicle fits.
Esta problemática aparece resuelta en la Patente EuropeaThis problem is resolved in the European Patent
1265761 , y la solución consiste en incorporar al circuito de los neumáticos una bomba de carga de aire, capaz de suministrar una presión netamente superior a la que da el citado compresor, de manera que colaborando con éste último es capaz de aumentar sustancialmente la presión, por ejemplo de una presión de 120 psi a una presión de 135 psi, con la que si que puede alcanzarse sin problema la presión nominal de los neumáticos.1265761, and the solution consists in incorporating an air load pump into the tire circuit, capable of supplying a pressure clearly higher than that given by the compressor, so that in collaboration with the latter it is capable of substantially increasing the pressure, for example, a pressure of 120 psi at a pressure of 135 psi, with which the nominal tire pressure can be reached without problem.
Esta solución resulta onerosa, debido a los costos de la bomba neumática y su instalación en el vehículo, y a veces crea también problemas de ubicación al no existir un espacio convenientemente acondicionado para ubicar dicha bomba.
DESCRIPCIÓN DE LA INVENCIÓNThis solution is costly, due to the costs of the pneumatic pump and its installation in the vehicle, and sometimes it also creates location problems as there is no conveniently conditioned space to locate said pump. DESCRIPTION OF THE INVENTION
El sistema que la invención propone resuelve de forma definitiva esta problemática con unos costos de instalación mínimos, prácticamente nulos, y con un posterior mantenimiento también nulo.The system proposed by the invention definitively solves this problem with minimal installation costs, practically null, and with subsequent maintenance also null.
Para ello y de forma mas concreta el sistema que se preconiza parte de la utilización como fuente de aire a presión, no del calderín del contenedor rodante, como se hace convencionalmente, sino de la cabeza tractora del vehículo, cuya presión es netamente superior a la de aquel y claramente suficiente para cubrir las exigencias de los neumáticos del contenedor rodante.For this, and more specifically, the system that is recommended as part of the use as a source of pressurized air, not of the boiler of the rolling container, as is done conventionally, but of the tractor unit of the vehicle, whose pressure is clearly higher than the of that and clearly sufficient to meet the demands of the tires of the rolling container.
De forma mas concreta en el calderín de la cabeza tractora se establece una toma convenientemente fijada a la pared posterior de dicha cabina, toma que tras un serpentín elástico se remata en un terminar de conexión rápida, del que es complementario otro existente en el contenedor rodante, y que a través del clásico filtro y unidad electrónica de control, alimenta de aire los neumáticos de dicho contenedor rodante, cuando la presión desciende en alguno de ellos por debajo de los límites preestablecidos.More specifically, a socket conveniently fixed to the rear wall of said cabin is established in the boiler of the tractor unit, taking that after an elastic coil it is finished off in a quick connect termination, of which another existing one in the rolling container is complementary , and that through the classic filter and electronic control unit, feeds the tires of said rolling container, when the pressure drops in any of them below the preset limits.
De acuerdo con esta estructuración el sistema permite las clásicas y frecuentes sustituciones de la cabeza tractora para un mismo contenedor rodante, y viceversa, sin mas que una manipulación de conexión/desconexión de un conector de acoplamiento rápido, cuya
manipulación resulta extraordinariamente rápida y sencilla.According to this structure, the system allows the classic and frequent replacement of the tractor unit for the same rolling container, and vice versa, without more than a manipulation of connection / disconnection of a quick coupling connector, whose handling is extraordinarily quick and easy.
DESCRIPCIÓN DE LOS DIBUJOSDESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego único de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado esquemáticamente y en alzado lateral, un semi-remolque dotado del sistema de inflado automático para sus ruedas, objeto de la presente invención, con detalles ampliados y en perspectiva de alguno de sus componentes.To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, a unique set of drawings is accompanied as an integral part of said description. where, for illustrative and non-limiting purposes, a semi-trailer equipped with an automatic inflation system for its wheels, object of the present invention, with enlarged and perspective details of some of its components, has been schematically represented and in side elevation.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En la figura reseñada se ha referenciado con (1) la cabeza tractora y con (2) el contenedor rodante, con (3) la "quinta rueda" o punto de acoplamiento amovible entre cabina tractora (1) y contenedor rodanteIn the above figure, reference has been made to (1) the tractor unit and (2) the rolling container, with (3) the "fifth wheel" or removable coupling point between tractor unit (1) and rolling container
(2), y con (4) las ruedas de dicho contenedor sobre las que actúa el sistema de inflado automático.(2), and (4) the wheels of said container on which the automatic inflation system acts.
Pues bien, como anteriormente se ha dicho, el sistema se basa en la utilización como fuente de aire a presión del calderín (5) de la cabina
tractora (1), que por normativa alcanza una presión considerablemente superior a la del calderín del contenedor rodante (2), concretamente una presión suficiente como para alcanzar el nivel de inflado previsto para las ruedas (4).Well, as previously stated, the system is based on the use as a source of pressurized air from the boiler (5) of the cabin tractor unit (1), which by regulation reaches a considerably higher pressure than the boiler of the rolling container (2), specifically a sufficient pressure to reach the level of inflation provided for the wheels (4).
Dado que el calderín (5) y las ruedas (4) están montadas sobre componentes del vehículo físicamente independientes entre sí, que incluso son frecuentemente intercambiables, como anteriormente se ha dicho, la toma de salida (6) del calderín (5) se fija en posición ascendente en la pared posterior de la cabina (1), se prolonga en un tramo espiral y elásticamente deformable (7), y se remata en un conector de acoplamiento rápido (8), como el mostrado en el detalle ampliado y correspondiente de la figura, finalizando aquí la parte de la instalación perteneciente a la cabeza tractoraSince the boiler (5) and the wheels (4) are mounted on physically independent components of the vehicle, which are even frequently interchangeable, as mentioned above, the outlet socket (6) of the boiler (5) is fixed in an upward position in the rear wall of the cabin (1), it is extended in a spiral and elastically deformable section (7), and is finished off in a quick coupling connector (8), as shown in the enlarged and corresponding detail of the figure, finishing here the part of the installation belonging to the tractor unit
(1).(one).
Por su parte, el contenedor rodante incorpora en su zona frontal un conector de acoplamiento rápido (9), complementario del conector (8) anteriormente citado, y dispuesto al mismo nivel, que remata la extremidad anterior y correspondiente de un conducto (10) que se dirige a las ruedasFor its part, the rolling container incorporates in its front area a quick coupling connector (9), complementary to the connector (8) mentioned above, and arranged at the same level, which ends the corresponding and anterior end of a duct (10) that goes to the wheels
(4) del contenedor (2), obviamente pasando a través de los clásicos filtros (11) para eliminación de impurezas en el aire, contando con una unidad electrónica de control (12) para limitar la presión suministrada por el calderín (5) a la presión nominal necesaria para la alimentación o inflado de las ruedas (4).
Como se desprende de lo anteriormente expuesto y ya se ha apuntado con anterioridad, el sistema se mantiene operativo de forma permanente e indefinida mientras un determinado contenedor rodante (2) se encuentre asociado a una determinada cabina o cabeza tractora (1), y cuando la carga tractora (1) abandona un determinado contenedor rodante(4) of the container (2), obviously passing through the classic filters (11) for removal of impurities in the air, with an electronic control unit (12) to limit the pressure supplied by the boiler (5) to the nominal pressure required for feeding or inflating the wheels (4). As can be seen from the foregoing and already noted above, the system remains permanently and indefinitely operational while a certain rolling container (2) is associated with a certain cab or tractor unit (1), and when the tractor load (1) leaves a certain rolling container
(2), por ejemplo para sustituirlo por otro, basta con desconectar los conectores (8 y 9), maniobra prácticamente instantánea y sumamente sencilla, y proceder a la conexión del conector (8) de la cabeza tractora al conector complementario (9) de que será portador el nuevo contenedor rodante.
(2), for example to replace it with another one, just disconnect the connectors (8 and 9), practically instantaneous and extremely simple maneuver, and proceed to the connection of the connector (8) of the tractor unit to the complementary connector (9) of The new rolling container will be the carrier.
