Abstract
The invention relates to a wheel pressure indicator for motor vehicles. The inventive indicator comprises a frame (1) which can be connected to the valve (4) of the vehicle wheel, instead of the standard cap, in a stable, impervious manner. A support (5) is disposed inside the aforementioned frame (1) for a battery (7) which is used to power a transmitter (8) that co-operates with a receiver (12) which is positioned at any suitable location inside the vehicle. The body of the transmitter (8) acts as a piston which can move inside the frame (1) against the power battery (7) under the effect of a spring (10). However, the piston movement is limited, such that the circuit remains open while there is sufficient pressure inside the tyre, said pressure reaching the front of the transmitter (10) body through holes (6) in the battery support (5). When the tyre pressure decreases normally, the spring (10) causes the closure of the circuit along with the transmission of the corresponding signal which can be seen inside the vehicle by means of one of the indicator lights (13) corresponding to the respective wheels.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo que ha sido previsto para controlar el nivel de presión en las ruedas de un vehículo automóvil, generando una señal cuando el nivel de dicha presión se sitúa por debajo de un limite preestablecido.The present invention relates to a device that has been provided to control the level of pressure in the wheels of a motor vehicle, generating a signal when the level of said pressure is below a preset limit.
El objeto de la invención es que desde el puesto de conducción del vehículo pueda controlarse en todo momento la presión de sus diferentes ruedas, por un lado para evitar desgastes prematuros y anormales de las mismas, por una presión de aire baja, y por otro para evitar posibles accidentes por las mismas circunstancias.The object of the invention is that from the driving position of the vehicle the pressure of its different wheels can be controlled at all times, on the one hand to avoid premature and abnormal wear of the same, by a low air pressure, and on the other to avoid possible accidents due to the same circumstances.
ANTECEDENTESDELAINVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido el tiempo de vida útil de los neumáticos es función de la presión de trabajo a que dichos neumáticos han sido sometidos, de manera que el kilometraje normal para un neumático a presión adecuada puede reducirse a la mitad si el neumático rueda en condiciones de presión inadecuada. Como también es sabido la seguridad del vehículo depende también con carácter fundamental de que la presión de los neumáticos sea la correcta.
Si bien en todas o la mayor parte de las estaciones de servicio se dispone de equipos de control y suministro de aire a presión, y si bien es cierto que los conductores son conscientes de que deben controlar periódicamente la presión de sus neumáticos, en ocasiones por olvido, en otras por dejadez y a veces por otras causas, dicho control no se realiza debidamente.As is known, the lifetime of the tires is a function of the working pressure to which said tires have been subjected, so that the normal mileage for a tire at adequate pressure can be reduced by half if the tire rolls in conditions of inadequate pressure As it is also known, the safety of the vehicle also depends fundamentally on the correct tire pressure. While all or most of the service stations are equipped with control equipment and supply of pressurized air, and while it is true that drivers are aware that they must periodically check the pressure of their tires, sometimes due to forgetfulness, sometimes because of neglect and sometimes for other reasons, such control is not carried out properly.
La solución óptima, como es evidente, sería disponer en el salpicadero del vehículo de pilotos señalizadores del nivel de presión en cada uno de los neumáticos, de manera que, por ejemplo con una señalización de color verde para una presión aceptable, pasen a una señalización de color rojo cuando la presión no sea la correcta.The optimal solution, as is evident, would be to provide the level of pressure indicators in each of the tires on the dashboard of the vehicle, so that, for example, with a green signaling for an acceptable pressure, they pass to a signaling red when the pressure is not correct.
En la actualidad ya existen dispositivos que cumplen esta función, dispositivos que se establecen en la llanta del vehículo, que resultan de complejo montaje, que consecuentemente resultan caros y de complicado mantenimiento, y que además se pierden si por cualquier circunstancia es necesario cambiar la llanta, ya que acompañan ineludiblemente a esta última.Nowadays there are already devices that fulfill this function, devices that are established in the vehicle's tire, that result from complex assembly, that consequently are expensive and of complicated maintenance, and that are also lost if for any circumstance it is necessary to change the tire , as they inevitably accompany the latter.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El señalizador que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, constituyendo una solución sencilla, eficaz y de fácil montaje.The signaling device that the invention proposes solves in a fully satisfactory manner the above-mentioned problem, constituting a simple, efficient and easy assembly solution.
Para ello y de forma más concreta dicho señalizador está constituido mediante la combinación funcional de un presiómetro y un trasmisor de onda corta, por un lado, y un receptor con sus
correspondientes señalizadores propiamente dichos por otro, estando presiómetro y transmisor establecidos eñ el seno de una carcasa acoplable mediante rosca a la válvula estándar de que disponen las ruedas de los vehículos, de manera que el dispositivo resulta fácilmente implantable sobre cada rueda del vehículo, sin más que sustituir el clásico tapón de la válvula estándar por la carcasa roscada que alberga presiómetro y transmisor.For this purpose and more specifically, said signaling device is constituted by the functional combination of a pressure gauge and a shortwave transmitter, on the one hand, and a receiver with its corresponding signaling devices, on the other hand, with a pressure gauge and transmitter being established within a housing that can be attached by means of a thread to the standard valve available to the wheels of the vehicles, so that the device is easily implantable on each wheel of the vehicle, without further than replace the classic plug of the standard valve with the threaded housing that houses pressure gauge and transmitter.
En cuanto al otro elemento, el receptor de onda corta, éste se fijará en cualquier lugar adecuado del salpicadero del vehículo y, preferentemente alimentado por la batería de este último, incorporará luces señalizadoras para cada una de las ruedas, por lo que dicho receptor deberá trabajar con al menos cuatro frecuencias distintas, en correspondencia con el mínimo número de ruedas del vehículo, y a su vez cada rueda llevará un transmisor de onda corta de diferente frecuencia que las restantes.As for the other element, the shortwave receiver, this will be fixed at any suitable place on the vehicle dashboard and, preferably powered by the latter's battery, will incorporate signaling lights for each of the wheels, so that receiver should work with at least four different frequencies, in correspondence with the minimum number of wheels of the vehicle, and in turn each wheel will carry a short wave transmitter of different frequency than the rest.
Para la alimentación eléctrica del transmisor se ha previsto la utilización de una pequeña pila de botón que, montada sobre el correspondiente soporte en el seno de la carcasa, normalmente se encuentra independizada del transmisor, por efecto de la propia presión existente en el neumático y que se transmite al dispositivo al acoplarse este último a la válvula estándar y provocar la apertura de la misma, mientras que un muelle recuperador, convenientemente tarado de acuerdo con la presión prevista en dicho neumático, desplaza el transmisor hacia la pila, provocando el cierre del circuito de alimentación del mismo, cuando la presión baja de un nivel preestablecido.For the power supply of the transmitter, it is planned to use a small button cell which, mounted on the corresponding support inside the housing, is normally independent of the transmitter, as a result of the actual pressure in the tire and that it is transmitted to the device when the latter is coupled to the standard valve and causes it to open, while a recovery spring, conveniently tared according to the pressure provided in said tire, moves the transmitter towards the battery, causing the circuit to close of feeding of the same, when the pressure falls of a preset level.
Dado que esta solución requiere de un perfecto ajuste entre el perímetro del transmisor y el cuerpo del dispositivo, se ha previsto una
variante de realización en la que en el seno del cuerpo del dispositivo se establece una membrana, que establece en el mismo dos cámaras superpuestas, una inferior en la que se aloja un presiómetro encargado de actuar sobre el pivote de la válvula, para apertura de la misma, y otra superior en la que se establecen las pilas de alimentación del transmisor, que lo hacen a través de un interruptor también asistido por un muelle, de manera que cuando la presión del neumático accede al interior de la carcasa deformando la citada membrana, ésta se expande en oposición a la válvula de la rueda y actúa sobre el interruptor, manteniendo abierto el circuito de alimentación del transmisor, mientras que cuando la presión decae en el interior del neumático, la curvatura de la membrana decrece y el interruptor cierra el citado circuito alimentando el transmisor para que se produzca la correspondiente señal en el salpicadero del vehículo.Since this solution requires a perfect fit between the perimeter of the transmitter and the body of the device, a variant of embodiment in which a membrane is established within the body of the device, which establishes two superimposed chambers therein, a lower one in which a pressure gauge is housed to act on the valve pivot, to open the same, and a superior one in which the transmitter's power batteries are established, which do so through a switch also assisted by a spring, so that when the tire pressure reaches the inside of the housing deforming the said membrane, it expands in opposition to the wheel valve and acts on the switch, keeping the transmitter supply circuit open, while when the pressure drops inside the tire, the curvature of the membrane decreases and the switch closes the mentioned circuit feeding the transmitter so that the corresponding signal is produced in the vehicle dashboard.

El soporte (5) está debidamente posicionado entre los dos sectores de la carcasa (1), para que a término de la fase de montaje del dispositivo, es decir de la carcasa (1) sobre la válvula estándar (4), dicho soporte (5) incida sobre el pivote (11) de la válvula (4) provocando la apertura de la misma, con lo que la presión existente en el interior del neumático se hace extensiva al interior de la carcasa (1) y a través de los
orificios (6) del soporte (5) actúa sobre el transmisor (8), desplazándolo hacia el fondo de la carcasa en contra" del muelle (10), a cuyo efecto la periferia del transmisor (8) debe ajustarse formal y dimensionalmente a la carcasa (1), estableciendo un cierre estanco con ella.The support (5) is properly positioned between the two sectors of the housing (1), so that at the end of the assembly phase of the device, that is to say the housing (1) on the standard valve (4), said support ( 5) It affects the pivot (11) of the valve (4) causing it to open, so that the pressure inside the tire is extended to the inside of the housing (1) and through the holes (6) of the support (5) act on the transmitter (8), moving it towards the bottom of the housing against "the spring (10), for which purpose the periphery of the transmitter (8) must be formally and dimensionally adjusted to the housing (1), establishing a tight seal with it.
Cuando la presión del neumático decae por debajo del nivel para el que ha sido tarado el resorte (10), éste empuja sobre el transmisor (8) desplazándolo hacia la pila (7) y provocando la activación de dicho transmisor que enviará una señal al complementario receptor (12), establecido por ejemplo en el salpicadero del vehículo, y que dispondrá para cada rueda de una pareja de püotos señalizadores (13), como por ejemplo uno verde y otro rojo, como ya se ha dicho con anterioridad, de manera que normalmente estará iluminado el verde, en situación normal de la rueda correspondiente, apagándose y encendiéndose el rojo cuando recibe la señal del correspondiente transmisor (8), debido a un descenso inaceptable en la presión de la rueda.When the tire pressure drops below the level for which the spring (10) has been tared, it pushes on the transmitter (8) moving it towards the battery (7) and causing the activation of said transmitter that will send a signal to the complementary receiver (12), established for example on the dashboard of the vehicle, and which will have for each wheel a pair of signaling points (13), such as a green one and a red one, as mentioned previously, so that normally the green will be illuminated, in normal situation of the corresponding wheel, the red will turn off and on when it receives the signal from the corresponding transmitter (8), due to an unacceptable decrease in the wheel pressure.
Obviamente los pilotos señalizadores (13) asociados al receptorObviously the signaling pilots (13) associated with the receiver
