Description

CARTER D'HUILE POUR MOTEUR THERMIQUE  OIL PAN FOR THERMAL ENGINE
L'invention concerne le domaine technique des carters d'huile pour moteurs thermiques de véhicules automobiles notamment. The invention relates to the technical field of oil sump for thermal engines of motor vehicles in particular.
On sait que les carters d'huile hybrides permettent d'alléger le moteur et donc d'améliorer les performances du véhicule ainsi équipé.  It is known that hybrid oil pans can lighten the engine and thus improve the performance of the vehicle thus equipped.
On connaît des carters d'huile hybrides en aluminium et en tôle, c'est-à-dire comportant un bac inférieur en tôle relativement plat et une semelle en aluminium complémentaire supportant le bac et fixée au moteur. Ces carters peuvent permettre de supporter des organes de véhicule, comme la boîte de vitesse ou le compresseur de climatisation.  Aluminum and sheet metal hybrid oil pans are known, that is to say having a lower tray in relatively flat sheet and a complementary aluminum sole supporting the tray and attached to the engine. These housings can support vehicle components, such as the gearbox or the air conditioning compressor.
On connaît également un carter d'huile hybride de moteur thermique de véhicule automobile dont le bac en matière plastique est fixé à une semelle en métal léger, le bac étant destiné à contenir l'huile de moteur dans une configuration relativement plane et la semelle étant configurée de façon complémentaire en liaison au moteur, à savoir sensiblement parallélépipédique rectangle. Ces carters peuvent permettre de supporter des organes de véhicule, comme la boîte de vitesse, et s'avèrent plus légers que les carters en aluminium et en tôle décrits plus haut.  Also known is a hybrid engine oil sump of a motor vehicle whose plastic tank is attached to a lightweight metal soleplate, the tray being intended to contain the engine oil in a relatively flat configuration and the sole being configured in a complementary manner in connection with the motor, namely substantially parallelepiped rectangle. These housings can support vehicle components, such as the gearbox, and are lighter than the aluminum and sheet metal housings described above.
Il existe un besoin pour un carter d'huile de moteur thermique de véhicule qui soit plus léger encore.  There is a need for a vehicle engine oil sump that is lighter still.
Il est proposé un carter d'huile pour moteur thermique comportant une semelle et un bac. Cette semelle est destinée à être fixée au moteur d'une part et au bac du carter d'huile d'autre part, et est conformée pour supporter en outre des organes de véhicule. Cette semelle comporte un bord d'appui inférieur de jonction étanche avec un bord d'appui complémentaire du bac. Le bord d'appui de jonction étanche de la semelle comporte au moins une large échancrure dans au moins une paroi latérale de la semelle.  It is proposed an engine oil sump having a sole and a tray. This soleplate is intended to be attached to the engine on the one hand and to the sump of the oil sump on the other hand, and is shaped to further support vehicle members. This sole has a lower support edge sealing junction with a complementary support edge of the tray. The sealing junction support edge of the sole comprises at least one wide notch in at least one side wall of the sole.
Ainsi, grâce à un tel étagement, la semelle est ajourée par rapport aux semelles de l'art antérieur, lesquelles présentent un bord d'appui inférieur sensiblement plan. Le bord d'appui inférieur de la semelle s'étend dans les trois dimensions, et non pas dans un plan comme dans l'art antérieur. La semelle peut ainsi être ramenée au moins en partie à une simple armature, de poids relativement faible. La semelle peut comporter des parties hautes et des parties basses, les parties basses correspondant à des contraintes particulières liées aux fonctionnalités de la semelle. Par exemple on peut prévoir une partie basse pour supporter un organe du type carter de distribution. Thus, thanks to such a step, the sole is perforated relative to the soles of the prior art, which have a substantially flat bottom support edge. The lower bearing edge of the sole extends in all three dimensions, and not in a plane as in the prior art. The sole can thus be reduced at least in part to a simple frame, of relatively low weight. The sole may have upper and lower parts, the lower parts corresponding to particular constraints related to the features of the sole. For example, a lower part may be provided to support a body of the type of distribution casing.
Une telle semelle est ainsi conformée en ceinture de la partie basse du moteur ou bas du moteur, avec une géométrie qui s'adapte au bas du moteur, comporte moins de matière qu'une semelle de carter classique, sensiblement parallélépipédique rectangle, et donc le carter d'huile est allégé relativement à un carter d'huile classique.  Such a sole is thus shaped as a belt of the lower part of the engine or bottom of the engine, with a geometry that fits the bottom of the engine, has less material than a conventional housing sump, substantially parallelepiped rectangle, and therefore the oil pan is lightened relative to a conventional oil sump.
La semelle et le bac ont ainsi des formes complémentaires, et viennent s'ajuster l'un dans l'autre pour former le carter.  The sole and the tray thus have complementary shapes, and fit one into the other to form the housing.
Le bord d'appui de la semelle et le bord d'appui du bac peuvent s'étendre sur toute la périphérie respectivement de la semelle et du bac.  The support edge of the sole and the bearing edge of the tray may extend over the entire periphery respectively of the sole and the tray.
Chaque large échancrure, dite aussi échancrure dans la présente demande, peut occuper tout ou partie d'un coté de la semelle, ou même plusieurs cotés adjacents de la semelle. La paroi latérale de la semelle correspondant à un côté donné peut avoir une ou plusieurs échancrures.  Each large notch, also called notch in the present application, may occupy all or part of one side of the sole, or even several adjacent sides of the sole. The side wall of the sole corresponding to a given side may have one or more indentations.
On entend par large échancrure dans une paroi de la semelle que la paroi est découpée avec une variation importante du bord d'appui inférieur de la paroi relativement à un bord inférieur qui serait sensiblement plan. La hauteur de la découpe peut représenter de 5% ou plus de la hauteur maximale des parois de la semelle, avantageusement 15% ou plus, avantageusement de 30% ou plus, et avantageusement 50% ou plus.  By broad notch in a wall of the sole is meant that the wall is cut with a large variation of the lower bearing edge of the wall relative to a lower edge which would be substantially plane. The height of the cut may be 5% or more of the maximum height of the walls of the sole, preferably 15% or more, preferably 30% or more, and preferably 50% or more.
Par « organe de véhicule », on entend les organes susceptibles d'être supportés au moins en partie par le carter, comme par exemple la boîte de vitesse, le carter de distribution ou le compresseur de climatisation.  By "vehicle member" means the members that can be supported at least in part by the housing, such as the gearbox, the timing case or the air conditioning compressor.
Les termes inférieur et supérieur, bas et haut, vertical et horizontal, sont à prendre au sens commun du terme lorsque la semelle est orientée telle qu'elle devrait l'être lorsque montée dans un véhicule. Ainsi, le vecteur gravité est un vecteur vertical, perpendiculaire aux plans horizontaux, et allant du haut vers le bas.  The terms lower and upper, low and high, vertical and horizontal, are to be taken in the common sense of the term when the sole is oriented as it should be when mounted in a vehicle. Thus, the gravity vector is a vertical vector, perpendicular to the horizontal planes, and going from top to bottom.
Cette semelle peut avantageusement comporter les parties de fixation du carter d'huile au moteur, en particulier au bas du moteur.  This soleplate may advantageously comprise the attachment parts of the oil sump to the engine, in particular at the bottom of the engine.
Cette semelle peut ainsi avantageusement comporter au moins une plaque de renfort support de partie lourde du véhicule, par exemple une plaque avant ou une plaque arrière, apte à supporter un carter de distribution du moteur, un compresseur ou une boîte de vitesses du véhicule. This soleplate may thus advantageously comprise at least one reinforcing plate for supporting the heavy part of the vehicle, for example a front plate or a rear plate, adapted to support an engine timing case, a compressor or a vehicle gearbox.
Il est aussi proposé une semelle telle que décrite ci-dessus.  It is also proposed a sole as described above.
II est en outre proposé un bac pour un carter d'huile pour moteur thermique, ce bac étant destiné à contenir de l'huile et à être fixé à une semelle agencée pour être elle-même fixée au moteur et pour supporter en outre au moins un organe de véhicule. Le bac est caractérisé en ce que son bord d'appui supérieur, destiné à former une jonction étanche avec un bord d'appui inférieur de la semelle, comporte au moins une large échancrure dans au moins une paroi latérale du bac.  It is further proposed a tray for an engine oil sump, this tray being intended to contain oil and to be attached to a soleplate arranged to be itself attached to the engine and to support moreover at least a vehicle member. The tray is characterized in that its upper bearing edge, intended to form a sealed junction with a lower bearing edge of the sole, comprises at least one wide notch in at least one side wall of the tray.
Ce bac présente donc des parois plus hautes que d'autres, et peut former avec la semelle décrite ci-dessus un carter d'huile hybride relativement léger.  This tray therefore has walls higher than others, and can form with the sole described above a relatively lightweight hybrid oil sump.
Chaque échancrure peut occuper tout ou partie d'un coté du bac, ou même plusieurs cotés adjacents du bac. La paroi latérale du bac correspondant à un côté donné peut avoir une ou plusieurs échancrures. Les parois peuvent donc en certains endroits avoir des hauteurs inférieures au niveau nominal de l'huile, une fois le carter d'huile assemblé sous le bloc moteur et rempli. Par « niveau nominal », on entend que le niveau d'huile se situe entre un minimum et un maximum prescrits par le constructeur. Le carter est ainsi conformé pour recevoir une quantité d'huile telle que au moins une partie du bord d'appui complémentaire de jonction étanche du bac soit située en dessous du niveau d'huile contenue dans le carter.  Each recess can occupy all or part of one side of the tray, or even several adjacent sides of the tray. The side wall of the tray corresponding to a given side may have one or more indentations. The walls can therefore in some places have heights below the nominal level of the oil, once the oil sump assembled under the engine block and filled. By "nominal level" is meant that the oil level is between a minimum and a maximum prescribed by the manufacturer. The housing is thus shaped to receive a quantity of oil such that at least a portion of the complementary sealing edge sealing junction of the tray is located below the oil level contained in the housing.
Le bac peut être avantageusement conformé avec une coque en matière plastique, ce qui allège encore le bac relativement à un bac en tôle.  The tray may be advantageously shaped with a plastic shell, which further lightens the tray relative to a sheet metal tray.
La matière plastique constitutive de la coque peut être une polyamide classique mais elle peut être chargée de fibres de verre, de fibres de carbone ou autre pour accroître sa résistance mécanique.  The plastic material constituting the shell may be a conventional polyamide but may be loaded with glass fibers, carbon fibers or the like to increase its mechanical strength.
La coque est avantageusement issue de moulage.  The shell is advantageously molded.
La coque peut avantageusement comporter au moins une partie des composants associés au traitement de l'huile formée en une seule pièce avec la coque, tels que des conduits de circuit d'huile et organes de traitement pour la circulation, la décantation, la filtration ou le refroidissement de l'huile, par exemple des conduits du circuit d'alimentation d'huile avec la pompe à huile intégrée, des conduits du circuit de filtre à huile avec l'élément de support du filtre à huile , des conduits du circuit de décantation de l'huile avec les chambres de décantation, des circuits d'échangeur thermique etc. The shell may advantageously comprise at least part of the components associated with the treatment of the oil formed in one piece with the shell, such as oil circuit conduits and treatment members for circulation, decantation, filtration or the cooling of the oil, for example ducts of the circuit oil supply with integrated oil pump, oil filter circuit conduits with oil filter support element, oil settling circuit conduits with settling chambers, circuit heat exchanger etc.
Ainsi, il n'est pas nécessaire de réaliser des usinages pour ces parties des composants comme pour les bacs de carter d'huile connus précités.  Thus, it is not necessary to perform machining for these parts of the components as for the above known oil sump tanks.
En outre, il est facile de réaliser par moulage au moins certaines des parties des composants associés, par exemple les pièces supports de clapet d 'échangeur d 'huile, de sonde de niveau d'huile , de connecteur de commande de pompe à huile, etc.  In addition, it is easy to mold at least some of the parts of the associated components, for example the oil exchanger check valve, oil level sensor, oil pump control connector parts, etc.
La coque en matière plastique peut donc ainsi comporter, outre une partie de bac à huile proprement dite, des parties d'extension en une seule pièce avec la coque, aptes à recevoir ou constituer au moins en partie des composants associés au traitement de l'huile, par exemple, les conduits de circuit d'huile à la pompe d'alimentation d'huile, les conduits de circuit de décantation de l'huile, les conduits de filtration de l'huile, les conduits de circuit d'huile à l'échangeur etc., mais aussi certaines des parties des composants associés, par exemple la pompe à huile, les chambres de décantation de l'huile et des pièces supports de composant, tout en assurant également les étanchéités des différentes interfaces, telles que par exemple l'élément de support du filtre à huile.  The plastic shell may thus comprise, in addition to a part of the oil tank itself, extension parts in one piece with the shell, adapted to receive or at least partly constitute components associated with the treatment of the oil, for example, the oil circuit lines to the oil feed pump, the oil decantation circuit lines, the oil filter lines, the oil circuit lines to the exchanger etc., but also some of the parts of the associated components, for example the oil pump, the oil settling chambers and component support parts, while also ensuring the sealing of the various interfaces, such as by example the support element of the oil filter.
Il en résulte également que relativement aux bacs de carter connus précités il n'est plus nécessaire de monter sur le bac les diverses parties précitées des composants associés au traitement de l'huile déjà intégrées à la coque ou corps du bac. Le montage du carter d'huile est donc plus facile et plus rapide.  It also results that relative to the known crankcase bins mentioned above it is no longer necessary to mount on the tank the various aforementioned parts of the components associated with the treatment of the oil already integrated into the hull or body of the tank. The assembly of the oil sump is therefore easier and faster.
La coque peut comprendre une surface intérieure et une surface extérieure, la surface intérieure étant celle destinée à entrer au moins en partie en contact avec l'huile.  The shell may comprise an inner surface and an outer surface, the inner surface being the one intended to at least partially come into contact with the oil.
La coque en matière plastique est avantageusement conformée selon une géométrie nervurée ou rainurée, la surface extérieure étant avantageusement alvéolée. Ces géométries peuvent permettre de conférer à la coque de la rigidité et de la solidité, par exemple pour des performances de silence acoustique au fonctionnement du moteur (absence de réponse aux vibrations), et pour la résistance face aux chocs de la route, chocs de pierres, chocs de trottoir etc. The plastic shell is advantageously shaped according to a ribbed or grooved geometry, the outer surface being advantageously honeycombed. These geometries can make it possible to give the shell rigidity and solidity, for example for performances of acoustic silence during engine operation. (lack of response to vibrations), and resistance to road shocks, rock shocks, sidewalks, etc.
Le nervurage décrit ci-dessus peut être avantageusement réalisé sur la surface de périphérie verticale ou proche (relativement au sens de montage sur le moteur) de la paroi de la coque. Ce nervurage ou rainurage peut comporter des ondulations de surface régulières ou non.  The ribbing described above may advantageously be performed on the vertical or near periphery surface (relative to the direction of mounting on the engine) of the wall of the shell. This ribbing or grooving may comprise regular undulating surface ripples.
Le carter peut avantageusement être un carter d'huile hybride, c'est-à-dire que le bac et la semelle sont réalisés en des matériaux différents. Le bac peut être réalisé en un matériau plus léger que celui de la semelle, et la semelle est réalisée dans un matériau plus résistant que celui du bac. Par exemple la semelle peut être en aluminium ou alliage d'aluminium, tandis que le bac peut être en plastique.  The housing may advantageously be a hybrid oil sump, that is to say that the tray and the sole are made of different materials. The tray can be made of a material lighter than that of the sole, and the sole is made of a stronger material than that of the tray. For example the sole may be aluminum or aluminum alloy, while the tray may be plastic.
Le carter peut avantageusement comporter un joint en élastomère disposé entre la semelle et le bac.  The housing may advantageously comprise an elastomer seal disposed between the sole and the tray.
Ce joint s'étend de façon étanche entre le bord d'appui supérieur du bac et le bord d'appui inférieur de la semelle. Ce joint peut permettre d'assurer l'étanchéité de l'assemblage de l'ensemble du bac et de la semelle du carter lorsque ce dernier est fixé au moteur.  This seal extends sealingly between the upper bearing edge of the tray and the lower bearing edge of the sole. This seal can be used to seal the assembly of the entire tank and the sole of the housing when the latter is attached to the engine.
Ce joint permet en outre par sa géométrie de découpe dans l'espace (non plane) d'atténuer les vibrations du dispositif de carter au fonctionnement du moteur. Le joint est disposé au dessus ou au dessous du niveau d'huile dans le bac en sorte de maximiser l'utilisation de matière plastique pour un gain de poids.  This seal also allows its cutting geometry in the space (not flat) to reduce the vibration of the housing device to the operation of the engine. The seal is placed above or below the oil level in the tray to maximize the use of plastic for weight gain.
L'invention n'est en rien limitée par la forme du profil du joint, ni par le ou les matériaux utilisés. Le joint peut par exemple avoir un profil en T, ou autre. Le joint peut être réalisé en élastomère de silicone, par exemple en poly(diméthylsiloxane) linéaire ou PDMS, et/ou en un ou plusieurs autres matériau(x).  The invention is in no way limited by the shape of the joint profile, nor by the material or materials used. The seal may for example have a T-shaped profile, or other. The seal may be made of silicone elastomer, for example linear poly (dimethylsiloxane) or PDMS, and / or one or more other material (x).
De plus, les bords d'appui du bac et/ou de la semelle en contact avec le joint en élastomère peuvent être laissés bruts, brut de moulage pour le bac et brut de coulée pour la semelle. La matière plastique du corps de bac et le joint en élastomère souple absorbent les imperfections des surfaces de bord en contact avec le joint. Par suite, l'usinage de ces surfaces, comme dans les carters d'huile hybrides classiques, peut être facultatif.  In addition, the support edges of the tray and / or the sole in contact with the elastomer seal may be left untreated, gross casting for the tray and raw casting for the sole. The plastic body of the tray body and the flexible elastomer seal absorb imperfections from the edge surfaces in contact with the seal. As a result, the machining of these surfaces, as in conventional hybrid oil sump, may be optional.
Il est également proposé un moteur de véhicule automobile comportant un carter d'huile tel que décrit ci-dessus. Il est en outre proposé un procédé d'utilisation du carter décrit ci- dessus. En particulier, le procédé peut avantageusement comprendre une étape de remplissage partiel du carter avec une quantité d'huile suffisante pour que au moins une partie du bord d'appui complémentaire de jonction étanche du bac soit située en dessous du niveau d'huile contenue dans le carter. It is also proposed a motor vehicle engine comprising an oil pan as described above. In addition, a method of using the housing described above is proposed. In particular, the method may advantageously comprise a step of partial filling of the housing with a sufficient amount of oil so that at least part of the complementary support edge sealing junction of the tray is located below the oil level contained in the housing.
Un mode de réalisation de l'invention est à présent décrit à titre non limitatif et en référence aux dessins annexés sur lesquels:  An embodiment of the invention is now described in a nonlimiting manner and with reference to the appended drawings in which:
- la figure 1 est une vue en perspective en éclaté d'un exemple de carter d'huile hybride selon un mode de réalisation de l'invention et,  FIG. 1 is an exploded perspective view of an example of a hybrid oil sump according to one embodiment of the invention and,
- la figure 2 est une vue en perspective du carter d'huile de la figure 1 monté.  - Figure 2 is a perspective view of the oil sump of Figure 1 mounted.
Avec référence aux figures, le carter d'huile 1 représenté comporte un bac inférieur 2 (relativement au sens de montage) apte à contenir de l'huile pour moteur thermique et une semelle métallique supérieure 5 destinée à être fixée à la partie basse (bas de moteur) non représentée d'un moteur thermique pour véhicule automobile.  With reference to the figures, the oil sump 1 shown has a lower tray 2 (relative to the direction of assembly) adapted to contain engine oil and an upper metal sole 5 to be fixed to the lower part (bottom motor) not shown of a motor vehicle heat engine.
Le bac inférieur 2 comprend une coque 3, issue de moulage en matière plastique, en polyamide par exemple. Cette matière résiste à la température élevée de l'huile au fonctionnement du moteur, de 100 à 140°C environ.  The lower tray 2 comprises a shell 3, resulting from molding plastic, polyamide for example. This material withstands the high temperature of the oil at engine operation, from 100 to 140 ° C.
La coque 3 comporte un bac proprement dit 7 contenant l'huile de moteur et des parties d'extension 9 également issues de moulage, aptes à recevoir ou constituer des composants associés au carter dans le traitement de l'huile, par exemple un circuit de conduit d'huile 1 1 disposé adjacent au bac 7 et comportant des conduits 13 acheminant l'huile à un échangeur thermique eau huile 15.  The shell 3 comprises a container proper 7 containing the engine oil and extension parts 9 also derived from molding, able to receive or constitute components associated with the crankcase in the treatment of the oil, for example a fuel system. oil duct 1 1 disposed adjacent to the tank 7 and having ducts 13 conveying the oil to an oil water heat exchanger 15.
D'autres éléments sont fixés à la coque tels une cloche de filtre à huile 17 par un conduit d'alimentation du filtre moulé dans le corps (non représenté), un clapet de filtre à huile 19 par une partie support moulée (non représentée), une sonde 21 de niveau d'huile dans le bac par une partie support moulée 22, un bouchon de vidange d'huile par une partie support moulée (non représentée), un connecteur de commande de pompe à huile 23 par une partie support moulée (24) etc.  Other elements are attached to the shell such as an oil filter bell 17 by a filter feed duct molded into the body (not shown), an oil filter valve 19 by a molded support portion (not shown) , an oil level probe 21 in the tray by a molded support portion 22, an oil drain plug by a molded support portion (not shown), an oil pump control connector 23 by a molded support portion (24) etc.
La coque 3 est nervurée 25 sur sa surface de paroi périphérique verticale et horizontale, ce qui accroît sa rigidité, sa résistance aux chocs de pierres et trottoir par exemple, et permet un silence acoustique au fonctionnement du moteur. La coque 3 comporte une surface intérieure en contact avec l'huile et une surface extérieure. The shell 3 is ribbed on its vertical and horizontal peripheral wall surface, which increases its rigidity, its resistance to shocks of stones and pavement for example, and allows an acoustic silence to the operation of the engine. The shell 3 has an inner surface in contact with the oil and an outer surface.
Selon un mode de réalisation non représenté, la coque 3 peut présenter sur sa surface extérieure un réseau d'alvéoles pour accroître la résistance aux chocs et améliorer également le silence acoustique.  According to an embodiment not shown, the shell 3 may have on its outer surface a network of cells to increase the impact resistance and also improve the acoustic silence.
Comme représenté sur les figures, un bord d'appui supérieur 37 du bac s'étend en étagement haut relativement à un bord d'appui inférieur 40 de façon à former deux découpes dans les deux parois opposées de plus grande longueur, lesquelles sont formées en échancrure 42 relativement aux découpes 40 des parois opposées de plus petite longueur. Les parois du bac sont donc ajourées.  As shown in the figures, an upper bearing edge 37 of the tray extends in high stance relative to a lower bearing edge 40 so as to form two cuts in the two opposite walls of greater length, which are formed in notch 42 relative to the cutouts 40 of the opposite walls of smaller length. The walls of the tray are openwork.
La semelle supérieure 5 est en métal léger, issue de moulage en aluminium par exemple. Cette semelle 5 est conformée de façon complémentaire au bac 2, comme une ceinture de liaison entre la partie basse ou bas du moteur et le bac 2, s 'étendant en périphérie du bas du moteur.  The upper sole 5 is lightweight metal, resulting from aluminum molding for example. This sole 5 is shaped complementary to the tray 2, as a connecting belt between the lower or lower part of the engine and the tray 2, extending at the periphery of the bottom of the engine.
Un bord d'appui inférieur 35 de la semelle a une forme sensiblement identique à celle du bord d'appui supérieur 37, 40 du bac. Ainsi, ce bord d'appui inférieur 35 forme deux découpes dans les parois correspondant aux deux cotés opposés de plus grande longueur de la semelle et comporte une échancrure 36 sur les parois correspondant aux deux cotés opposés de plus petite longueur de la semelle. Le bord complémentaire 37 du bac peut donc être en certains endroits en dessous du niveau d'huile contenue dans le carter, une fois le carter d'huile monté sous le bloc moteur et rempli.  A lower bearing edge 35 of the sole has a shape substantially identical to that of the upper bearing edge 37, 40 of the tray. Thus, this lower bearing edge 35 forms two cuts in the walls corresponding to the two opposite sides of greater length of the sole and comprises a notch 36 on the walls corresponding to the two opposite sides of smaller length of the sole. The additional edge 37 of the tray may therefore be in some places below the oil level contained in the housing, once the oil pan mounted under the engine block and filled.
Un joint d'étanchéité 33 en élastomère est interposé entre la semelle 5 et le bac inférieur 2 lorsque le bac et la semelle sont assemblés l'un à l'autre (au moyen de vis). Le joint 33 est appliqué en pression respectivement entre le bord de périphérie inférieur 35 de la semelle 5 et le bord d'application supérieur 37, 40 correspondant de périphérie du corps de bac 2.  A seal 33 elastomer is interposed between the sole 5 and the lower tray 2 when the tray and the sole are assembled to each other (by means of screws). The seal 33 is applied in pressure respectively between the lower periphery edge 35 of the sole 5 and the upper application edge 37, 40 corresponding to the periphery of the container body 2.
Ce joint 33 s'étend dans l'espace (n'est pas plat) en sorte d'épouser la géométrie de découpe du bac 2 et de la semelle 5, en particulier, le joint 33 comporte deux parties opposées, une partie avant 39 et une partie arrière 41 , en décrochement vers le bas relativement aux parties longitudinales plus étendues 43 de ce joint 33. Le joint 33 peut être monté sur les bords d'application 35, 37, 40 et 42 de la semelle 5 et du bac 2 laissés bruts de moulage, la matière plastique du corps du bac pouvant absorber en combinaison avec le joint élastomère les imperfections du bord de semelle. This seal 33 extends in space (is not flat) so as to match the cutting geometry of the tray 2 and the sole 5, in particular, the seal 33 has two opposite parts, a front portion 39 and a rear portion 41, recessed downward relative to the longer longitudinal portions 43 of this seal 33. The seal 33 can be mounted on the application edges 35, 37, 40 and 42 of the sole 5 and the tray 2 left raw molding, the plastic body of the tray can absorb in combination with the elastomer seal imperfections of the sole edge.
Selon un mode de réalisation, ce joint 33 peut être en élastomère avec un profil en T, et le bord d'appui du bac 2 peut être conformé de façon à définir une gorge apte à recevoir le pied du T du joint 33.  According to one embodiment, this seal 33 may be of elastomer with a T-shaped profile, and the bearing edge of the tray 2 may be shaped so as to define a groove adapted to receive the foot of the T of the seal 33.
Une partie arrière à forme de plaque 27 (à droite sur le dessin) de cette semelle est plus étendue et plus rigide. Cette partie 27 peut recevoir en fixation la boîte de vitesses du véhicule (non représentée). D'autres éléments non représentés peuvent être fixés à cette semelle. Par exemple un carter de distribution du moteur peut être fixé sur une partie de plaque avant 29, et un compresseur de climatisation du véhicule peut être fixé sur une des parois correspondant aux cotés de plus grande longueur.  A rear plate-shaped portion 27 (right in the drawing) of this sole is wider and more rigid. This part 27 can receive the gearbox of the vehicle (not shown). Other elements not shown can be attached to this sole. For example, an engine timing case may be attached to a front plate portion 29, and a vehicle air conditioning compressor may be attached to one of the walls corresponding to the longer sides.
A la partie supérieure de la semelle sont formées les parties de fixation 31 au bas du moteur, notamment des alésages recevant des vis de fixation au moteur.  At the upper part of the sole are formed the fastening portions 31 at the bottom of the engine, in particular bores receiving fastening screws to the engine.
L'invention ne se limite pas aux modes de réalisation décrits précédemment. Par exemple, le joint 33 peut être du silicone déposé sur le bord d'appui du bac 2 sans nécessité de gorge dans ce bord, ou le joint 33 peut comporter plusieurs pièces en élastomère ou silicone.  The invention is not limited to the embodiments described above. For example, the seal 33 may be silicone deposited on the support edge of the tray 2 without the need for a groove in this edge, or the seal 33 may comprise several pieces of elastomer or silicone.
Ce qui précède montre les avantages d'un carter d'huile de moteur thermique de véhicule selon un mode de réalisation de l'invention, avec une semelle allégée, un bac issu de moulage en matière plastique à configuration intégrée des composants associés au carter d'huile, en particulier du circuit d'huile à l'échangeur thermique, circuit d'alimentation d'huile, circuit de filtre à huile etc. Il est ainsi possible de configurer librement la semelle support relativement à des éléments de fixation annexe, en particulier la boîte de vitesse du véhicule, le compresseur de climatisation du véhicule, le carter de distribution du moteur etc.. Parmi ces avantages, on peut en outre citer le gain de masse du carter d'huile et la facilité de réalisation et de montage de l'ensemble relativement à un carter d'huile hybride classique.  The foregoing shows the advantages of a vehicle engine oil sump according to one embodiment of the invention, with a lightened soleplate, a tray resulting from plastic molding with an integrated configuration of the components associated with the oil sump. oil, especially from the oil circuit to the heat exchanger, oil supply circuit, oil filter circuit, and so on. It is thus possible to freely configure the support base relative to attachment elements, in particular the vehicle gearbox, the air conditioning compressor of the vehicle, the engine timing case, etc. Among these advantages, it is possible to besides mention the weight gain of the oil sump and the ease of production and assembly of the assembly relative to a conventional hybrid oil sump.
