Description

Actionneur électromagnétique. Electromagnetic actuator.
L'invention concerne un actionneur électromagnétique. Dans les moteurs alternatifs étudiés actuellement, on envisage d'actionner les soupapes d'admission et d'échappement par des actionneurs électromagnétiques. Un actionneur électromagnétique comprend en général au moins deux bobines associées à des noyaux ferromagnétiques et disposées en regard l'une de l'autre, et un élément mobile s'étendant entre les bobines et associé à une tige d'actionnement. La tige d'actionnement coopère avec l'extrémité de la queue d'une soupape pour actionner celle-ci. Lors de l'assemblage de ces actionneurs, les bobines ne sont pas solidaires entre elles. Elles doivent donc être placées une par une dans le châssis de l'actionneur, ce qui augmente le temps d'assemblage. Des câbles flexibles sont ensuite fixés aux bobines pour les relier à un connecteur d'alimentation. Cette connexion est rendue difficile par le fait que \es bobines sont déjà dans le châssis de l'actionneur, et donc que les extrémités des conducteurs constituant les bobines sont d'accès difficile.The invention relates to an electromagnetic actuator. In the alternative engines currently studied, it is envisaged to actuate the intake and exhaust valves by electromagnetic actuators. An electromagnetic actuator generally comprises at least two coils associated with ferromagnetic cores and arranged opposite one another, and a movable element extending between the coils and associated with an actuating rod. The actuating rod cooperates with the end of the stem of a valve to actuate the latter. During the assembly of these actuators, the coils are not integral with each other. They must therefore be placed one by one in the actuator frame, which increases the assembly time. Flexible cables are then attached to the coils to connect them to a power connector. This connection is made difficult by the fact that the coils are already in the chassis of the actuator, and therefore that the ends of the conductors constituting the coils are difficult to access.
Alternativement, si on commence l'assemblage par la liaison des bobines au connecteur, le transport d'ensemble des bobines pour les placer dans le châssis de l'actionneur est malaisé. Selon l'invention, les bobines comportent des conducteurs ayant des extrémités s'étendant transversalement à un axe des bobines et directement fixées à des broches portées par une plaque fixée sur un côté des bobines et comportant un circuit de liaison avec un connecteur également porté par la plaque. Ainsi, la plaque assure tout à la fois la connexion électrique des bobines au connecteur et une solidarisation mécanique des bobines entre elles. Cette disposition permet d'effectuer l'assemblage de la carte sur les bobines hors du châssis de l'actionneur, puis de transporter l'ensemble ainsi solidarisé dans le châssis. L'assemblage de l'actionneur est ainsi considérablement sim- plifié.Alternatively, if one starts the assembly by connecting the coils to the connector, the overall transport of the coils to place them in the actuator chassis is difficult. According to the invention, the coils comprise conductors having ends extending transversely to an axis of the coils and directly fixed to pins carried by a plate fixed on one side of the coils and comprising a connection circuit with a connector also carried by the plaque. Thus, the plate ensures both the electrical connection of the coils to the connector and a mechanical connection of the coils to each other. This arrangement makes it possible to assemble the card on the coils outside the chassis of the actuator, then to transport the assembly thus secured in the chassis. The assembly of the actuator is thus considerably simplified.
Avantageusement, chaque extrémité d'un conducteur s'étend dans un perçage de la plaque et débouche de façon adjacente à une broche sur une face de la plaque opposée aux bobines.Advantageously, each end of a conductor extends in a hole in the plate and opens adjacent to a pin on a face of the plate opposite the coils.
Ainsi, l'extrémité du conducteur est automatiquement positionnée en regard d'une broche lors de son introduction dans le perçage correspondant et peut être soudée à la broche par une pince chauffante dont les mouvements ne sont pas gênés par les bobines.Thus, the end of the conductor is automatically positioned opposite a spindle when it is inserted into the corresponding hole and can be soldered to the spindle by a heating pliers whose movements are not hampered by the coils.
Avantageusement, les bobines sont recouvertes de matière isolante comportant des bossages extérieurs auxquels la plaque de liaison est fixée. Les bobines comportent également des cales d'entretoisement prenant appui les unes sur les autres pour maintenir un espacement entre les bobines. De préférence, les cales d'entretoisement sont intégrées à la matière isolante, et sont formées par les bossages extérieurs.Advantageously, the coils are covered with insulating material comprising external bosses to which the connection plate is fixed. The coils also include spacer blocks bearing on each other to maintain a spacing between the coils. Preferably, the spacer blocks are integrated into the insulating material, and are formed by the external bosses.
Selon un mode de réalisation dans lequel l'actionneur comprend quatre bobines associées selon deux paires adjacentes, les bobines de position correspondante de chaque paire ont des noyaux ferromagnétiques portés par un support ferromagnétique commun. La mise en place des bobines sur le support commun réalise ainsi un début de solidification des deux paires de bobines. Selon un autre aspect de l'invention, les noyaux ferromagnétiques s'étendent en saillie des bobines du côté de l'élément mobile. Ces noyaux ferromagnétiques forment ainsi une butée de l'élément mobile, ce qui évite une détérioration des bobines.According to an embodiment in which the actuator comprises four coils associated in two adjacent pairs, the coils of corresponding position of each pair have ferromagnetic cores carried by a common ferromagnetic support. The positioning of the coils on the common support thus achieves the start of solidification of the two pairs of coils. According to another aspect of the invention, the ferromagnetic cores project from the coils on the side of the movable element. These ferromagnetic cores thus form a stop for the movable element, which prevents damage to the coils.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lumière de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention en relation aux figures parmi lesquelles :Other characteristics and advantages of the invention will appear more clearly in the light of the following description of a particular non-limiting embodiment of the invention in relation to the figures among which:
- la figure 1 est une vue en perspective éclatée d'une partie d'un actionneur selon l'invention;- Figure 1 is an exploded perspective view of part of an actuator according to the invention;
- la figure 2 est une vue en coupe selon II-II de la figure 1 de l'actionneur ;- Figure 2 is a sectional view along II-II of Figure 1 of the actuator;
- la figure 3 est une vue de face de l'actionneur des figures 1 et 2 après montage ;- Figure 3 is a front view of the actuator of Figures 1 and 2 after assembly;
- la figure 4 est une vue en perspective agrandie d'une broche de connexion à l'extrémité d'un conducteur. L'actionneur décrit ici est adapté pour commander l'ouverture et la fermeture de deux soupapes (non représentées) d'axes parallèles. L'actionneur est sensiblement symétrique selon un plan P définissant une séparation entre les éléments de l'actionneur destinés chacun à la commande d'une soupape différente. L'actionneur comporte deux éléments mobiles 1 montés à coulisse- ment sur l'actionneur chacun selon un axe 100. Ces éléments mobiles 1 comportent chacun une tige d'actionnement ou poussoir 2, dont une extrémité 3 est saillante de l'actionneur pour coopérer avec l'extrémité de la queue d'une soupape. L'autre extrémité du poussoir 2 est solidaire d'une palette 4 s'étendant perpendiculairement à l'axe 100, et astreinte à se déplacer entre deux bobines 5 et 6 fixes disposées en regard l'une de l'autre selon l'axe 100.- Figure 4 is an enlarged perspective view of a connection pin at the end of a conductor. The actuator described here is suitable for controlling the opening and closing of two valves (not shown) with parallel axes. The actuator is substantially symmetrical along a plane P defining a separation between the elements of the actuator each intended for the control of a different valve. The actuator comprises two movable elements 1 mounted to slide- ment on the actuator each along an axis 100. These movable elements 1 each comprise an actuating rod or pusher 2, one end 3 of which protrudes from the actuator to cooperate with the end of the stem of a valve. The other end of the pusher 2 is secured to a pallet 4 extending perpendicularly to the axis 100, and forced to move between two fixed coils 5 and 6 arranged opposite one another along the axis 100.
Chaque bobine comporte un conducteur 7 noyé par moulage dans une matière isolante 8 de forme sensiblement parallélépipédique, le conducteur 7 étant enroulé de façon à ménager un creux central 9 de la bobine.Each coil has a conductor 7 embedded by molding in an insulating material 8 of substantially parallelepiped shape, the conductor 7 being wound so as to provide a central hollow 9 of the coil.
Les deux bobines 5 sont enchâssées à force sur un support 10 commun réalisé en tôles de matériau ferromagnétique découpées et empilées les unes sur les autres. Le support 10 comporte des noyaux 11 s'étendant dans les creux centraux 9 des bobines 5. Les noyaux 11 sont percés pour permettre le passage des poussoirs 2. Le support 10 comprend par ailleurs une aile centrale 12 et deux ailes d'extrémité 13 encadrant les bobines 5.The two coils 5 are force-fitted on a common support 10 made of sheets of ferromagnetic material cut and stacked on top of each other. The support 10 comprises cores 11 extending in the central recesses 9 of the coils 5. The cores 11 are drilled to allow the passage of the pushers 2. The support 10 also comprises a central wing 12 and two end wings 13 framing the coils 5.
Les deux bobines 6 sont enchâssées à force sur un support 14 en tous points similaire au support 10, à l'exception des noyaux des bobines 6 qui ne sont pas percés. Les noyaux 11 et les ailes 12,13 des supports 10 et 14 dépassent en saillie des faces en regard des bobines 5 et 6 de façon à former une butée pour les palettes 4 lors de leur déplacement.The two coils 6 are force-fitted on a support 14 at all points similar to the support 10, with the exception of the cores of the coils 6 which are not pierced. The cores 11 and the wings 12, 13 of the supports 10 and 14 protrude from the facing faces of the coils 5 and 6 so as to form a stop for the pallets 4 during their movement.
Des bossages 15 sont réalisés lors du moulage de la matière isolante 8 pour s'étendre en saillie des faces en regard des bobines 5 et 6. Les bossages 15 d'une bobine forment des cales d'entretoisement qui coopèrent avec les bossages 15 de la bobine en regard pour maintenir un espacement déterminé entre les bobines.Bosses 15 are produced during the molding of the insulating material 8 to extend projecting from the facing faces of the coils 5 and 6. The bosses 15 of a coil form spacer blocks which cooperate with the bosses 15 of the opposite coil to maintain a determined spacing between the coils.
Sur chaque bobine, des extrémités 16 du conducteur 7 sont saillantes et s'étendent perpendiculairement à une face latérale 17 de la bobine. Les faces latérales 17 des quatre bobines forment un plan d'appui pour un circuit imprimé 18 fixé sur chaque bobine à l'aide de vis 19 vissées chacune dans un bossage 15 d'une bobine.On each coil, the ends 16 of the conductor 7 are protruding and extend perpendicular to a lateral face 17 of the coil. The lateral faces 17 of the four coils form a support plane for a printed circuit 18 fixed to each coil using screws 19 each screwed into a boss 15 of a coil.
Chaque extrémités 16 s'étend dans un perçage 20 du circuit imprimé 18 et débouche au voisinage d'une broche 21 sur une face du circuit imprimé 18 opposée aux bobines. Chaque broche 21 comporte une partie 22 parallèle à l'extrémité 16 et soudée à cette dernière. Cette partie 22 est reliée de façon stable sur le circuit imprimé 18 par un trépied 23.Each end 16 extends in a bore 20 of the printed circuit 18 and opens in the vicinity of a pin 21 on a face of the printed circuit 18 opposite the coils. Each pin 21 has a part 22 parallel to the end 16 and welded to the latter. This part 22 is stably connected to the printed circuit 18 by a tripod 23.
Les extrémités du trépied 23 traversent le circuit imprimé 18 pour être électriquement reliées avec des pistes conductrices 24 réalisées sur la face du circuit imprimé en regard des bobines. Les pistes conductrices 24 forment un circuit de liaison des extrémités 16 à un connecteur 25 porté par le circuit imprimé 18.The ends of the tripod 23 pass through the printed circuit 18 to be electrically connected with conductive tracks 24 made on the face of the printed circuit opposite the coils. The conductive tracks 24 form a circuit connecting the ends 16 to a connector 25 carried by the printed circuit 18.
La procédure d'assemblage de l'actionneur est la suivante : - on rapporte les bobines 5 sur le support 10, puis on rapporte les bobines 6 sur le support 14 ;The procedure for assembling the actuator is as follows: - the coils 5 are attached to the support 10, then the coils 6 are attached to the support 14;
- on enfile les éléments mobiles 1 dans les perçages du support 10, puis on présente les deux ensembles de bobines ainsi constitués de façon à faire coopérer les bossages 15 de chaque bobine avec ceux de la bobine en regard de l'autre ensemble ;- The movable elements 1 are threaded into the holes of the support 10, then the two sets of coils thus formed are presented so as to make the bosses 15 of each coil cooperate with those of the coil facing the other assembly;
- on présente et on visse le circuit imprimé 18 sur les faces latérales 17 des bobines ainsi disposées ;- We present and screw the printed circuit 18 on the side faces 17 of the coils thus arranged;
- on soude chaque extrémité 16 à la broche 21 adjacente, par exemple au moyen d'Une pince chauffante assurant un apport de soudure. Cette opération est facilitée par le fait que les broches 21 se trouvent sur une face du circuit imprimé 18 facilement accessible, et par le fait que les broches 21 sont suffisamment éloignées l'une de l'autre pour permettre le passage aisé d'une telle pince.- Each end 16 is welded to the adjacent pin 21, for example by means of a heating clamp ensuring a solder supply. This operation is facilitated by the fact that the pins 21 are on one side of the printed circuit 18 easily accessible, and by the fact that the pins 21 are sufficiently distant from each other to allow easy passage of such a clamp.
L'ensemble des extrémités 16 est ainsi directement câblé au con- necteur 25 sans qu'il y ait lieu de les prolonger chacune par un câble flexible. En outre, les quatre bobines sont rendues mécaniquement solidaires l'une de l'autre par le circuit imprimé 18, et peuvent donc être transportées en bloc pour être disposées dans un châssis non représenté de l'actionneur.The assembly of the ends 16 is thus directly wired to the connector 25 without there being any need to extend them each with a flexible cable. In addition, the four coils are made mechanically integral with one another by the printed circuit 18, and can therefore be transported as a whole to be placed in a chassis (not shown) of the actuator.
De plus, tous les composants (broches, connecteur) du circuit impri- mé 18 sont situés sur une même face de celui-ci, et peuvent donc être soudés à la vague sur le circuit imprimé 18 préalablement à son assemblage aux bobines.In addition, all the components (pins, connector) of the printed circuit 18 are located on the same face of the latter, and can therefore be wave soldered on the printed circuit 18 before it is assembled with the coils.
L'invention n'est pas limitée au mode particulier de réalisation qui vient d'être décrit, mais bien au contraire entend couvrir toute variante qui entre dans le cadre de l'invention tel que défini par les revendications. En particulier, bien que l'actionneur ait été décrit avec un circuit imprimé 18, on pourra prévoir l'utilisation d'une plaque en matériau synthétique dans laquelle sont noyés des conducteurs réalisés par emboutissage d'une tôle métallique pour former le circuit de liaison. Bien que l'actionneur ait été décrit avec un support commun à deux bobines, on peut remplacer ce support par deux noyaux ferromagnétiques indépendants, et solidariser les deux bobines munies de ces noyaux par des moyens de liaison sur leurs faces en regard.The invention is not limited to the particular embodiment which has just been described, but on the contrary intends to cover any variant which falls within the scope of the invention as defined by the claims. In particular, although the actuator has been described with a printed circuit 18, provision may be made for the use of a plate of synthetic material in which are embedded conductors produced by stamping a metal sheet to form the connection circuit . Although the actuator has been described with a support common to two coils, this support can be replaced by two independent ferromagnetic cores, and the two coils provided with these cores are joined together by means of connection on their opposite faces.
Bien que les bossages extérieurs des bobines servent ici de cales d'entretoisement des bobines, on peut prévoir l'utilisation de cales d'entretoisement rapportées séparément des bossages extérieurs.Although the external bosses of the coils serve here as spacer blocks for the coils, provision may be made for the use of spacer blocks added separately from the external bosses.
Bien que le circuit imprimé soit ici vissé aux bobines, on peut prévoir tout autre type de fixation, comme un clipsage ou un collage.Although the printed circuit is here screwed to the coils, one can provide any other type of fixing, such as clipping or bonding.
On peut également prévoir un organe de solidarisation supplémen- taire des bobines entre elles, par exemple des cavaliers fixés aux bobines sur une face latérale opposée au circuit de liaison.It is also possible to provide an additional securing member for the coils with one another, for example jumpers fixed to the coils on a lateral face opposite the connection circuit.
Bien que le circuit imprimé 18 ait été décrit comme ne portant que le connecteur 25 et les broches 21 , on peut y rapporter des composants électroni- ques de gestion de l'alimentation des conducteurs des bobines. On peut aussi y rapporter des connexions à un capteur associé aux éléments mobiles 1. Although the printed circuit 18 has been described as bearing only the connector 25 and the pins 21, it is possible to relate to it electronic components for managing the power supply of the conductors of the coils. It is also possible to relate to it connections to a sensor associated with the mobile elements 1.
