Description

Vanne de gonflage et de dégonflage pour roue de véhicule Inflation and deflation valve for vehicle wheel
Le secteur technique de la présente invention est celui des vannes de gonflage des pneumatiques de véhicule et des systèmes de gonflage et de dégonflage intégrant une telle vanne .The technical sector of the present invention is that of inflation valves for vehicle tires and inflation and deflation systems incorporating such a valve.
De nombreux documents décrivent des vannes de gonflage et de dégonflage de pneumatiques. On citera à titre d'exemple les brevets EP-296017, EP-0246953 et le brevet FR-2731655. Ce dernier brevet décrit plus particulièrement un système de contrôle à distance du gonflage et du dégonflage d'un pneumatique adapté à des véhicules légers dont les pneumatiques ont une pression de l'ordre de 2 bar. Toutefois, il n'est pas prévu de dégonflage lent du pneumatique, ce qui peut s'avérer nécessaire dans certaines configurations de circulation du véhicule.Numerous documents describe inflation and deflation valves for tires. By way of example, mention will be made of patents EP-296017, EP-0246953 and patent FR-2731655. This latter patent more particularly describes a remote control system for inflating and deflating a tire suitable for light vehicles whose tires have a pressure of the order of 2 bar. However, there is no provision for slow deflation of the tire, which may prove to be necessary in certain vehicle circulation configurations.
Le but de la présente invention est de fournir une vanne permettant d'assurer un dégonflage lent du pneumatique . L'invention a donc pour objet une vanne de roue pour pneumatique de véhicule du type comportant un clapet anti- retour, deux demi-corps délimitant entre eux une cavité et assemblés avec interposition d'une membrane assurant entre lesdits demi-corps une fonction de joint d' étanchéité, le clapet anti-retour étant constitué par un élément tubulaire solidaire de la membrane à l'intérieur duquel l'élément de fermeture est mobile entre un siège et une base, l'élément de fermeture étant appliqué contre le siège par la pression régnant dans le pneumatique, caractérisé en ce que l'élément de fermeture est soumis à l'action d'un champ magnétique assurant son maintien au niveau de la base pour maintenir ledit clapet ouvert et assurer un dégonflage lent du pneumatique.The object of the present invention is to provide a valve making it possible to ensure slow deflation of the tire. The subject of the invention is therefore a wheel valve for a vehicle tire of the type comprising a non-return valve, two half-bodies delimiting between them a cavity and assembled with the interposition of a membrane ensuring between said half-bodies a function of seal, the non-return valve being constituted by a tubular element integral with the membrane inside which the closing element is movable between a seat and a base, the closing element being applied against the seat by the pressure prevailing in the tire, characterized in that the closing element is subjected to the action of a magnetic field ensuring its maintenance at the base to keep said valve open and ensuring slow deflation of the tire.
Selon une caractéristique de l'invention, l'élément de fermeture est une bille en acier coopérant avec le siège délimité par une bague insérée dans l'élément tubulaire.According to a characteristic of the invention, the closing element is a steel ball cooperating with the seat delimited by a ring inserted in the tubular element.
Selon une autre caractéristique de l'invention, le champ magnétique est produit à l'aide d'un élément aimanté disposé au voisinage de la membrane.According to another characteristic of the invention, the magnetic field is produced using a magnetic element arranged in the vicinity of the membrane.
Selon une autre caractéristique de l'invention, l'élément aimanté se présente sous la forme d'une bague disposée dans une échancrure de la bague. Selon une autre caractéristique de l'invention, une grille est disposée entre la bague et l'embase de l'élément tubulaire pour limiter le déplacement de la bille.According to another characteristic of the invention, the magnetic element is in the form of a ring arranged in a notch of the ring. According to another characteristic of the invention, a grid is arranged between the ring and the base of the tubular element to limit the movement of the ball.
L'invention concerne également une installation de commande à distance du dégonflage lent d'une roue de pneumatique incluant une vanne, caractérisée en ce qu'elle comprend une première électrovanne disposée sur le circuit d'alimentation de ladite vanne et trois électrovannes disposées en aval de la première.The invention also relates to an installation for remote control of the slow deflation of a tire wheel including a valve, characterized in that it comprises a first solenoid valve disposed on the supply circuit of said valve and three solenoid valves arranged downstream of the first.
Avantageusement, la première électrovanne est à trois voies.Advantageously, the first solenoid valve is three-way.
Avantageusement, on applique une pression d'air comprimé sur la bille à l'aide de l' électrovanne pour assurer son eloignement du siège et mettre ainsi en communication le pneumatique en communication avec le milieu extérieur à travers l' électrovanne .Advantageously, a pressure of compressed air is applied to the ball using the solenoid valve to ensure its distance from the seat and thus to put the tire in communication with the outside environment through the solenoid valve.
Un tout premier avantage de la vanne selon 1 ' invention réside dans le fait que la vanne est retenue au niveau de l'aimant tant que le débit d'air évacué est faible.A very first advantage of the valve according to the invention lies in the fact that the valve is retained at the magnet as long as the exhaust air flow rate is low.
Un autre avantage réside dans la simplicité de réalisation du système de dégonflage lent.Another advantage lies in the simplicity of construction of the slow deflation system.
D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels : - la figure 1 est une coupe diamétrale de la vanne selon l'invention,Other characteristics, details and advantages of the invention will emerge more clearly from the description given below by way of indication in relation to the drawings in which: FIG. 1 is a diametrical section of the valve according to the invention,
- les figures 2 et 3 représente deux autres positions de fonctionnement de la vanne, etFIGS. 2 and 3 represent two other operating positions of the valve, and
- la figure 4 représente un exemple de réalisation de l'installation de commande à distance.- Figure 4 shows an embodiment of the remote control installation.
Sur la figure 1, on a représenté une vanne 1 en coupe constituée d'un corps 2 composé de deux demi-corps 3 et 4 , réalisés en une matière appropriée, assemblés de manière démontable ou non, face contre face, et usinés pour délimiter ensemble une cavité 5. Les demi-corps 3 et 4 pincent entre eux et par leurs bords périphériques une membrane 6 déformable élastiquement qui divise la cavité 5 en deux chambres 7a et 7b. Le demi-corps 3 possède un raccord 8 s 'ouvrant dans la chambre 7a et destiné à être mis en relation avec la ligne 9 du circuit d'asservissement décrit plus complètement en relation avec la figure 4. Le demi-corps 4 présente avantageusement dans sa partie centrale un alésage 10 s' ouvrant dans la chambre 7b et destiné à être raccordé par tout moyen adéquat à un conduit d'alimentation de la roue du véhicule. La membrane 6 est associée à un clapet asservi 11 constitué d'un élément tubulaire 12 relié à une embase 13 dont la couronne périphérique est intégrée dans la membrane 6 qui délimite un bourrelet 14 ou joint annulaire destiné à entourer l'orifice de l'alésage 10 afin d'isoler ce dernier de la chambre 7b. Sur la figure, on voit que le bourrelet 14 est formé directement par la membrane 6. L'élément tubulaire 12 est soumis à l'action d'un ressort hélicoïdal 15 prenant appui sur l'embase 13 et la paroi interne du demi-corps 3. L'élément tubulaire 12 intègre d'autre part une gaine 16 délimitant un siège 17 sur lequel une bille 18 vient en appui afin fermer la chambre 19 délimitée par la gaine 16 en communication avec l'alésage 10. Le déplacement de la bille 18 est limité par une grille 20 pincée entre l'embase 13 et la gaine 16.In Figure 1, there is shown a valve 1 in section consisting of a body 2 composed of two half-bodies 3 and 4 , made of a suitable material, assembled so removable or not, face against face, and machined to delimit together a cavity 5. The half-bodies 3 and 4 pinch between them and by their peripheral edges an elastically deformable membrane 6 which divides the cavity 5 into two chambers 7a and 7b. The half-body 3 has a connector 8 opening into the chamber 7a and intended to be put in relation with the line 9 of the control circuit described more fully in relation to FIG. 4. The half-body 4 advantageously has in its central part a bore 10 opening in the chamber 7b and intended to be connected by any suitable means to a supply duct of the vehicle wheel. The membrane 6 is associated with a controlled valve 11 consisting of a tubular element 12 connected to a base 13 whose peripheral ring is integrated in the membrane 6 which delimits a bead 14 or annular seal intended to surround the orifice of the bore 10 in order to isolate the latter from chamber 7b. In the figure, it can be seen that the bead 14 is formed directly by the membrane 6. The tubular element 12 is subjected to the action of a helical spring 15 bearing on the base 13 and the internal wall of the half-body 3. The tubular element 12 also integrates a sheath 16 delimiting a seat 17 on which a ball 18 comes to bear in order to close the chamber 19 delimited by the sheath 16 in communication with the bore 10. The movement of the ball 18 is limited by a grid 20 pinched between the base 13 and the sheath 16.
Le rôle du ressort 15 est de repousser constamment la membrane 6 vers le demi-corps 4 et maintenir le bourrelet 14 contre ce demi-corps et isoler ainsi l'alésage 10 de la chambre 7b qui communique avec le milieu ambiant par des lumières d'échappement 21.The role of the spring 15 is to constantly push the membrane 6 towards the half-body 4 and maintain the bead 14 against this half-body and thus isolate the bore 10 of the chamber 7b which communicates with the ambient medium by lights of exhaust 21.
La gaine 16 est munie au niveau de l'embase 13 d'une échancrure dans laquelle est inséré un élément aimanté 22. La bille 18 constituant un élément de fermeture de la chambre 19 est soumis à l'action d'un champ magnétique lorsqu'elle est au niveau de la grille 20 assurant son maintien au niveau de l'embase 13 pour maintenir ledit clapet ouvert et assurer un dégonflage lent du pneumatique comme il sera expliqué ci-après. La force de l'aimant 22 est calculée de façon à vaincre au moins le poids de la bille 18 et la résultante des forces aérodynamiques exercées par le débit d'air traversant la chambre 19.The sheath 16 is provided at the base 13 with a notch in which a magnetic element 22 is inserted. The ball 18 constituting an element for closing the chamber 19 is subjected to the action of a magnetic field when it is at the grid 20 ensuring its maintenance at the base 13 to maintain said valve open and ensure slow deflation of the tire as will be explained below. The force of the magnet 22 is calculated so as to overcome at least the weight of the ball 18 and the result of the aerodynamic forces exerted by the air flow passing through the chamber 19.
Dans la configuration représentée sur la figure 1 la vanne 1 n'est pas sollicitée par le système de gonflage et de dégonflage. On suppose le pneumatique déjà gonflé et la pression maintient le clapet 11 fermé en appliquant la bille 18 constamment contre le siège 17 pour isoler la chambre 7a. D'autre part, le ressort 15 maintient le bourrelet 14 constamment en appui contre le demi-corps 4 et ferme ainsi la chambre 7b.In the configuration shown in Figure 1 the valve 1 is not stressed by the inflation and deflation system. It is assumed that the tire is already inflated and the pressure keeps the valve 11 closed by applying the ball 18 constantly against the seat 17 to isolate the chamber 7a. On the other hand, the spring 15 maintains the bead 14 constantly in abutment against the half-body 4 and thus closes the chamber 7b.
Le dégonflage du pneumatique en communication avec l'alésage 10 est assuré de deux manières différente. Sur la figure 2, on a représenté la position de la vanne 1 de dégonflage rapide telle que décrite dans le brevet français cité antérieurement. A cette fin, de façon connue, on met en dépression la chambre 7a pour venir agir de façon antagoniste au ressort 15 et ramener la membrane 6 dans la position représentée. Le bourrelet 14 n'est donc plus en appui contre le demi-corps 4 et la communication est établie entre l'alésage 10 et les lumières d'échappement 21 pour évacuer rapidement vers l'extérieur le fluide sous pression du pneumatique.The deflation of the tire in communication with the bore 10 is ensured in two different ways. In Figure 2, there is shown the position of the valve 1 for rapid deflation as described in the French patent cited above. To this end, in known manner, the chamber 7a is placed under vacuum in order to act antagonistically to the spring 15 and bring the membrane 6 back to the position shown. The bead 14 is therefore no longer in abutment against the half-body 4 and the communication is established between the bore 10 and the exhaust ports 21 to rapidly evacuate the fluid under pressure from the tire.
Sur la figure 3, on a représenté la position de la vanne 1 de dégonflage lent du pneumatique. Cette possibilité est importante pour le conducteur du véhicule car le dégonflage rapide peut mettre en danger la conduite de ce véhicule. On considère la position de départ représentée sur la figure 1 et on commande une brève entrée d' air comprimé par le raccord 8. Ceci a pour effet de repousser la bille 18 contre la grille 20 qui est alors retenue grâce au champ magnétique engendré par l'aimant 22. Le pneumatique est alors mis en communication par le raccord 8 à travers la chambre 19 avec le conduit 9. Ainsi, on évacue du pneumatique un débit d'air calibré sans provoquer un déplacement de la bille 18 retenu par l'aimant 22.FIG. 3 shows the position of the valve 1 for slow deflation of the tire. This possibility is important for the driver of the vehicle because rapid deflation can endanger the operation of this vehicle. Consider the starting position shown in Figure 1 and control a brief entry of compressed air through the connector 8. This has the effect of pushing the ball 18 against the grid 20 which is then retained by the magnetic field generated by the magnet 22. The tire is then placed in communication by the connector 8 through the chamber 19 with the conduit 9. Thus, a calibrated air flow is removed from the tire without causing the ball 18 retained by the magnet to move. 22.
La vanne 1 ainsi réalisée peut être intégrée dans une installation de commande à distance du ou des pneumatiques d'un véhicule comme représenté sur la figure 4. Sur cette figure, on a représenté une installation 30 constituée d'un ensemble 31 au niveau de chaque roue 33 du véhicule non représenté et un ensemble 32 au niveau de la cabine du conducteur, du châssis du véhicule ou en tout autre endroit approprié. Chaque roue 33 est fixée de manière appropriée à un moyeu 34 par l'intermédiaire d'une jante 35. Le moyeu 34 est relié de manière classique à un axe de roulement 36 du véhicule. La vanne 1 est fixée à la roue 37 de manière appropriée à l'aide d'un joint tournant 41 et est reliée à une valve 38 du pneumatique 33 grâce à une canalisation 39. Comme représenté sur la figure, la vanne 1 est montée proche de l'axe xx' de l'axe 36 de la roue. Cet axe 36 est percé d'une canalisation 40 pour mettre en communication l'ensemble 32 et la vanne 1 à l'aide d'un conduit 42. L'ensemble 32 est constitué de quatre électrovannes 43, 44, 45 et 46.The valve 1 thus produced can be integrated into a remote control installation for the tire or tires of a vehicle as shown in FIG. 4. In this figure, there is shown an installation 30 consisting of an assembly 31 at each wheel 33 of the vehicle not shown and an assembly 32 at the level of the driver's cabin, the chassis of the vehicle or at any other suitable location. Each wheel 33 is suitably fixed to a hub 34 by means of a rim 35. The hub 34 is conventionally connected to a rolling axle 36 of the vehicle. The valve 1 is fixed to the wheel 37 in an appropriate manner using a rotary joint 41 and is connected to a valve 38 of the tire 33 by means of a pipe 39. As shown in the figure, the valve 1 is mounted close from the axis xx 'to the axis 36 of the wheel. This axis 36 is pierced with a pipe 40 for placing the assembly 32 and the valve 1 in communication using a conduit 42. The assembly 32 consists of four solenoid valves 43, 44, 45 and 46.
L' électrovanne 43 est une électrovanne trois voies qui est positionnée en amont des trois autres électrovannes. Elle assure l'ouverture et la fermeture de la canalisation 42 vers la vanne 1. Elle assure également une fonction remise à l'air libre à l'aide de la troisième voie indiquée. Ainsi, il suffit de dupliquer seulement la vanne 4 autant de fois que le véhicule possède de roues.The solenoid valve 43 is a three-way solenoid valve which is positioned upstream of the other three solenoid valves. It ensures the opening and closing of the pipe 42 towards the valve 1. It also provides a function released into the open air using the third channel indicated. Thus, it suffices to duplicate only the valve 4 as many times as the vehicle has wheels.
L' électrovanne 44 est en relation avec une source d'air comprimé 47 permettant d'alimenter la roue 33 en air comprimé.The solenoid valve 44 is in relation to a source of compressed air 47 making it possible to supply the wheel 33 with compressed air.
L' électrovanne 45 est en relation avec une source 48 de mise en dépression pour commander la vanne 1 en dépression.The solenoid valve 45 is in relation to a source 48 of vacuuming for controlling the valve 1 in vacuum.
L' électrovanne 46 est en relation avec un mécanisme 49 d'étranglement de la canalisation commandé par une bobine 50 pour commander un débit d'air variable en fonction du nombre de vannes 43 pilotées vers les roues 33.The solenoid valve 46 is in relation to a mechanism 49 for throttling the pipeline controlled by a coil 50 to control a variable air flow as a function of the number of valves 43 piloted towards the wheels 33.
Le fonctionnement général de ce système est identique à celui du système décrit dans le brevet français cité précédemment en ce qui concerne le gonflage et le dégonflage des roues. Toutefois, la fonction de dégonflage lent est assurée de la manière suivante. On envoie une pulsation d'air comprimé à l'aide de l' électrovanne 44, en l'ouvrant et en la refermant rapidement, vers la vanne 1 qui décolle la bille 18 de son siège. La bille vient alors occuper la position représentée sur la figure 3 c'est-à- dire au voisinage de la grille 20. Le pneu de la roue 33 est mis alors en communication avec la chambre 19, puis le raccord 8, puis la canalisation 40, puis la canalisation 42 et l' électrovanne 46, l' électrovanne 43 étant ouverte et les électrovannes 44 et 45 étant fermées. Lorsque le dégonflage atteint le niveau désiré, on ferme 1' électrovanne 43 et la bille reprend sa position initiale représentée sur la figure 1.The general operation of this system is identical to that of the system described in the French patent cited. previously with regard to inflation and deflation of the wheels. However, the slow deflation function is performed as follows. A pulse of compressed air is sent using the solenoid valve 44, by opening and closing it quickly, towards the valve 1 which takes off the ball 18 from its seat. The ball then comes to occupy the position shown in FIG. 3, that is to say in the vicinity of the grid 20. The tire of the wheel 33 is then placed in communication with the chamber 19, then the connector 8, then the pipe. 40, then the pipe 42 and the solenoid valve 46, the solenoid valve 43 being open and the solenoid valves 44 and 45 being closed. When the deflation reaches the desired level, the solenoid valve 43 is closed and the ball returns to its initial position shown in FIG. 1.
Le dégonflage rapide est assuré en commandant l'ouverture de 1 ' électrovanne 45 qui par la dépression appliquée dans la chambre 7a comprime le ressort 15 et met en communication le pneumatique avec la chambre 7b et les lumières d'échappement 21 avec le milieu extérieur.Rapid deflation is ensured by controlling the opening of the solenoid valve 45 which by the vacuum applied in the chamber 7a compresses the spring 15 and places the tire in communication with the chamber 7b and the exhaust ports 21 with the external environment.
L'installation selon l'invention permet également un contrôle aisé de la pression de gonflage à l'aide d'un manomètre 51 connecté sur la canalisation 52 reliant les électrovannes 43 et 46. On décolle la bille 18 comme expliqué précédemment et on laisse l' électrovanne 43 ouverte et 1 ' électrovanne 46 fermée et après stabilisation de la pression on lit la mesure. Après lecture, on ouvre la 1 ' électrovanne 43 pour fermer la vanne 1 en provoquant le déplacement de la bille et son application contre le siège. The installation according to the invention also allows easy control of the inflation pressure using a pressure gauge 51 connected to the pipe 52 connecting the solenoid valves 43 and 46. The ball 18 is lifted off as explained above and the solenoid valve 43 open and solenoid valve 46 closed and after stabilization of the pressure the measurement is read. After reading, the solenoid valve 43 is opened to close the valve 1 by causing the movement of the ball and its application against the seat.
