Description
EQUIPEMENT ELECTRIQUE POUR VEHICULES AUTOMOBILESELECTRICAL EQUIPMENT FOR MOTOR VEHICLES
La présente invention concerne le domaine des équipements électriques pour véhicules automobiles. Elle s'applique notamment, mais non exclusivement, aux systèmes de pompage de carburant, par exemple d'essence, dans un réservoir de véhicule automobile.The present invention relates to the field of electrical equipment for motor vehicles. It applies in particular, but not exclusively, to systems for pumping fuel, for example petrol, into a tank of a motor vehicle.
Plus précisément encore, la présente invention concerne un dispositif de filtrage contre les perturbations électriques et/ou électromagnétiques, pour de tels équipements, en particulier contre les perturbations véhiculées sur les fils d'alimentation de tels équipements.More precisely still, the present invention relates to a filtering device against electrical and / or electromagnetic disturbances, for such equipment, in particular against the disturbances conveyed on the supply wires of such equipment.
Les normes actuelles imposent de limiter les perturbations électromagnétiques en dessous de seuils de plus en plus faibles.Current standards impose to limit electromagnetic disturbances below increasingly low thresholds.
On a schématisé sur la figure 1 annexée, la structure d'un équipement classique de pompage de carburant muni d'un dispositif de filtrage connu.The structure of a conventional fuel pumping equipment provided with a known filtering device has been shown diagrammatically in attached FIG. 1.
On aperçoit sur cette figure 1 une pompe 10 actionnée par un moteur électrique à courant continu dont la crépine d'entrée 12 est placée à proximité du fond d'un réservoir de carburant 14. La sortie en carburant de la pompe 10 est référencée 13. La pompe 10 est alimentée électriquement, à partir d'une batterie 20, par deux lignes 22, 24. Et ces lignes 22, 24 sont associées à un filtre 30. Selon la représentation de la figure 1, le filtre 30 comprend deux selfs de choc 32, 34 placées respectivement sur les lignes 22, 24 et un condensateur 36 placé entre les lignes 22, 24, côté batterie 20. Par ailleurs, la ligne de masse 24 est reliée par une ligne électrique auxiliaire 25, au boîtier métallique 11 de la pompe 10. De très nombreux équipements de type illustré sur la figure 1 ont été installés par le passé sur des véhicules automobiles.We can see in this figure 1 a pump 10 actuated by a direct current electric motor whose inlet strainer 12 is placed near the bottom of a fuel tank 14. The fuel outlet of the pump 10 is referenced 13. The pump 10 is supplied electrically, from a battery 20, by two lines 22, 24. And these lines 22, 24 are associated with a filter 30. According to the representation of FIG. 1, the filter 30 comprises two inductors of shock 32, 34 placed respectively on the lines 22, 24 and a capacitor 36 placed between the lines 22, 24, on the battery side 20. Furthermore, the ground line 24 is connected by an auxiliary electrical line 25, to the metal housing 11 of the pump 10. Many types of equipment illustrated in Figure 1 have been installed in the past on motor vehicles.
La réponse en dBμV en fonction de la fréquence est illustrée sur la courbe I sur la figure 2. Sur la même figure 2 le gabarit ou limite imposée par les normes actuelles est référencée IL On voit clairement que pour les fréquences élevées (typiquement supérieures à 60MHz), le filtre connu ne permet pas de respecter les normes puisque le niveau de perturbation dépasse la limite autorisée.The response in dBμV as a function of frequency is illustrated on curve I in FIG. 2. In the same FIG. 2, the template or limit imposed by current standards is referenced IL. It is clearly seen that for high frequencies (typically greater than 60 MHz) ), the known filter does not make it possible to comply with the standards since the level of disturbance exceeds the authorized limit.
Différentes propositions ont été faites pour tenter d'améliorer la situation. Il a été ainsi proposé de supprimer la ligne 25 en considérant que celle-ci pouvait peut être jouer un rôle néfaste d'antenne. Cependant, cette tentative n'a pas donné satisfaction. La réponse alors obtenue est référencée III sur la figure 2.Various proposals have been made to try to improve the situation. It has thus been proposed to delete line 25 by considering that it could perhaps play a harmful role as an antenna. However, this attempt was not successful. The response then obtained is referenced III in FIG. 2.
Il a également été proposé de surdimensionner (en valeur et volume) les selfs 32, 34 par rapport aux dispositifs antérieurs connus. Cependant, cette tentative n'a pas non plus donnée satisfaction car elle n'a pas permis de respecter l'encombrement imposé par l'environnement mécanique interne et externe des équipements concernes, en particulier dans le cas d'un système de pompage de carburant'. La présente invention a pour but de proposer de nouveaux moyens permettant de réduire le niveau de perturbation électriques et/ou électromagnétiques, par rapport aux dispositifs de filtrage connus.It has also been proposed to oversize (in value and volume) the inductors 32, 34 compared to the known prior devices. However, this attempt was not satisfactory either because it did not allow the space imposed by the internal and external mechanical environment of the equipment concerned to be respected, in particular in the case of a fuel pumping system ' . The object of the present invention is to propose new means making it possible to reduce the level of electrical and / or electromagnetic disturbance, compared with known filtering devices.
Ce but est atteint dans le cadre de la présente invention grâce à un équipement comprenant un organe électrique comportant un carter au moins partiellement électriquement conducteur, un filtre électrique disposé sur les lignes d'alimentation de l'organe électrique, et des moyens de liaison électrique entre le carter et la ligne de masse du filtre, caractérisé par le fait que les moyens de liaison entre le carter de l'organe électrique et la ligne de masse du filtre comprennent au moins un composant série de nature selfique. Selon une autre caractéristique avantageuse de la présente invention, le composant série de liaison de nature selfique est formé d'un barreau ou anneau de ferrite.This object is achieved in the context of the present invention by means of equipment comprising an electrical member comprising an at least partially electrically conductive casing, an electrical filter disposed on the supply lines of the electrical member, and electrical connection means. between the casing and the earth line of the filter, characterized in that the connecting means between the casing of the electrical component and the earth line of the filter comprise at least one series component of selfic nature. According to another advantageous characteristic of the present invention, the series connection component of selfic nature is formed of a bar or ferrite ring.
D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre, et en regard des dessins annexés, donnés à titre exemple non limitatif et sur lesquels :Other characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings, given by way of nonlimiting example and in which:
- la figure 1 précédemment décrite représente schématiquement un système connu conforme à l'état de la technique,FIG. 1 previously described diagrammatically represents a known system conforming to the state of the art,
- la figure 2 précédemment partiellement décrite représente en I et III les courbes de réponse de différents filtres conformes à l'état de la technique, en II un gabarit limite imposé par les normes et en IV la réponse d'un filtre conforme à la présente invention,- Figure 2 previously partially described in I and III the response curves of different filters according to the state of the art, in II a limit template imposed by standards and in IV the response of a filter in accordance with this invention,
- la figure 3 représente un système conforme à la présente invention, et - la figure 4 représente une vue plus en détail d'un dispositif de pompage conforme à une variante préférentielle de la présente invention.FIG. 3 represents a system in accordance with the present invention, and - Figure 4 shows a more detailed view of a pumping device according to a preferred embodiment of the present invention.
On retrouve sur la figure 3, un équipement comprenant dans un réservoir de carburant 14 une pompe 10 à carter 11 au moins partiellement conducteur comportant une crépine d'entrée 12 située à proximité du fond du réservoir 14 et une sortie de carburant 13. La pompe 10 est actionnée par un moteur électrique à courant continu, par deux lignes 22, 24, à partir d'une batterie 20.We find in Figure 3, an equipment comprising in a fuel tank 14 a pump 10 with casing 11 at least partially conductive comprising an inlet strainer 12 located near the bottom of the tank 14 and a fuel outlet 13. The pump 10 is actuated by a direct current electric motor, by two lines 22, 24, from a battery 20.
Les deux lignes 22, 24, sont associées à un filtre 30. Celui-ci comprend deux selfs de choc 32, 34 placées respectivement sur les lignes 22, 24, et un condensateur 36 placé entre les lignes 22 et 24 côté batterie 20.The two lines 22, 24 are associated with a filter 30. This comprises two shock inductors 32, 34 placed respectively on the lines 22, 24, and a capacitor 36 placed between the lines 22 and 24 on the battery side 20.
Comme on le voit sur la figure 3, selon une caractéristique essentielle de l'invention, la ligne 24, dans son tronçon situé entre la self de choc 34 et la batterie 20, est reliée au carter électriquement conducteur 11 de la pompe 10, par un composant 40 de nature selfique. Plus précisément encore, de préférence, dans le cadre de la présente invention, ce composant 40 est formé d'un barreau ou d'un noyau de ferrite, voire d'un anneau de ferrite. Cependant, dans le cadre de l'invention le composant 40 peut également être formé d'une bobine.As can be seen in FIG. 3, according to an essential characteristic of the invention, the line 24, in its section located between the shock inductor 34 and the battery 20, is connected to the electrically conductive casing 11 of the pump 10, by a component 40 of selfic nature. More precisely still, preferably, within the framework of the present invention, this component 40 is formed of a bar or a ferrite core, or even a ferrite ring. However, in the context of the invention the component 40 can also be formed from a coil.
La réponse obtenue grâce à l'adjonction d'un tel composant 40 conforme à l'invention est illustrée en IV sur la figure 2. Un examen rapide de cette figure montre que le composant 40 permet de tenir le cahier des charges imposé par les normes actuelles.The response obtained by the addition of such a component 40 according to the invention is illustrated in IV in FIG. 2. A quick examination of this figure shows that the component 40 makes it possible to keep the specifications imposed by the standards current.
Plus précisément, l'on constate que grâce à la présence du composant 40 constitué de préférence d'une ferrite, l'on supprime toute augmentation de la réponse à haute fréquence, alors que c'était le cas en I avec une mise à la masse directe du filtre, et que l'on ne constate pas de pic intermédiaire comme en III sans mise à la masse.More specifically, it can be seen that thanks to the presence of the component 40 preferably made of a ferrite, any increase in the high frequency response is suppressed, whereas this was the case in I with a setting to the direct mass of the filter, and that there is no intermediate peak as in III without grounding.
Ainsi, l'ajout d'une mini self ou noyau de ferrite 40 sur la connexion de mise à la masse, permet d'obtenir une courbe acceptable qui corrige le défaut rencontré selon l'état de la technique pour les hautes fréquences, notamment entreThus, the addition of a mini self or ferrite core 40 on the grounding connection makes it possible to obtain an acceptable curve which corrects the defect encountered according to the state of the art for high frequencies, in particular between
60 et 110MHz. Ainsi, la présente invention permet en particulier de respecter les normes définies en bande FM (88 à 108MHz) et FMX (65 à 88MHz). Le filtre 30 peut être fixé par tout moyen approprié sur le corps de pompe 10 lui-même. Par exemple et de préférence le filtre 30 peut être clipsé sur la pompe 10 en partie supérieure de celle-ci.60 and 110MHz. Thus, the present invention makes it possible in particular to comply with the standards defined in the FM (88 to 108 MHz) and FMX (65 to 88 MHz) band. The filter 30 can be fixed by any suitable means to the pump body 10 itself. For example and preferably the filter 30 can be clipped onto the pump 10 in the upper part thereof.
On a illustré sur la figure 4, une variante préférentielle d'installation du filtre 30 en partie supérieure de la pompe 10.FIG. 4 shows a preferred variant for installing the filter 30 in the upper part of the pump 10.
Sur cette figure 4, on a référencé 15 l'entrée du fluide, 16 les aimants du moteur électrique, 17 le collecteur, 18 les balais et 19 le couvercle de sortie classique de la pompe 10. De nos jours, dans la plupart des cas, la partie supérieure de la pompe, notamment le couvercle 19, est réalisée en matière plastique. Elle est donc susceptible de laisser passer des rayonnements électromagnétiques produits par le frottement des balais 18 sur le collecteur 17 du moteur.In this FIG. 4, reference has been made to 15 the fluid inlet, 16 the magnets of the electric motor, 17 the collector, 18 the brushes and 19 the conventional outlet cover of the pump 10. Nowadays, in most cases , the upper part of the pump, in particular the cover 19, is made of plastic. It is therefore likely to let pass electromagnetic radiation produced by the friction of the brushes 18 on the manifold 17 of the motor.
Pour améliorer l'élimination des perturbations électromagnétiques sans modifier fondamentalement la structure des pompes actuelles, il est ainsi proposé dans le cadre de la présente invention d'adjoindre au carter métallique 11 de la pompe 10, un corps métallique 50 recouvrant complètement les balais 18 et le porte balai associé, ainsi que le filtre 30. Ce corps 50 couvre donc le couvercle 19.To improve the elimination of electromagnetic disturbances without fundamentally modifying the structure of current pumps, it is thus proposed in the context of the present invention to add to the metal casing 11 of the pump 10, a metal body 50 completely covering the brushes 18 and the associated brush holder, as well as the filter 30. This body 50 therefore covers the cover 19.
Bien entendu, ce boîtier additionnel 50, réalisé de préférence en métal, et formant cage de Faraday, doit être relié mécaniquement et électriquement au carter métallique 11 de la pompe 10. Il est par ailleurs relié par l'intermédiaire du composant 40 à la ligne de masse 24.Of course, this additional box 50, preferably made of metal, and forming a Faraday cage, must be mechanically and electrically connected to the metal casing 11 of the pump 10. It is also connected via the component 40 to the line. mass 24.
L'ajout d'une telle cage métallique 50 clipsée sur le corps de pompe 11 permet de réduire les perturbations électromagnétiques émises par rayonnement et conduites sur les fils d'alimentation 22, 24. Ce boîtier 50 formant cage de Faraday est composé de préférence d'un manchon cylindrique 52 d'axe vertical coaxial du corps de pompe 10 obturé en partie supérieure par une cloison transversale 54 ajourée seulement pour permettre le passage de la sortie de fluide 13 et le passage des connexions électriques vers le filtre 30 propres à assurer l'alimentation du moteur à courant continu. Il a été constaté que l'adjonction d'un tel boîtier 50 formant cage de Faraday permet de réduire sensiblement les perturbations électromagnétiques rayonnées, en particulier sur la bande de fréquence 30MHz à 1000MHz. Cependant, le boîtier formant cage de Faraday 50 peut faire l'objet de nombreux modes de réalisation. En particulier, on peut concevoir que selon certaines variantes, ce boîtier 50 ne soit pas circulaire de révolution.The addition of such a metal cage 50 clipped to the pump body 11 makes it possible to reduce the electromagnetic disturbances emitted by radiation and conducted on the supply wires 22, 24. This housing 50 forming Faraday cage is preferably composed of: '' a cylindrical sleeve 52 of coaxial vertical axis of the pump body 10 closed at the top by a transverse partition 54 perforated only to allow the passage of the fluid outlet 13 and the passage of the electrical connections to the filter 30 suitable for ensuring the DC motor supply. It has been found that the addition of such a box 50 forming a Faraday cage makes it possible to significantly reduce the radiated electromagnetic disturbances, in particular on the frequency band 30 MHz to 1000 MHz. However, the Faraday 50 cage housing can be the subject of numerous embodiments. In particular, it is conceivable that according to certain variants, this box 50 is not circular in revolution.
De préférence, le boîtier 50 est réalisé en un alliage cuivreux, par exemple un cupro Nickel ou encore un alliage de bronze, par exemple CuSn3Zn9.Preferably, the housing 50 is made of a copper alloy, for example a Cupro Nickel or a bronze alloy, for example CuSn3Zn9.
Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toute variante conforme à son esprit. Of course the present invention is not limited to the particular embodiments which have just been described, but extends to any variant in accordance with its spirit.
