Description
E SUPPORT La présente invention concerne un dispositif de support moteur destiné à équipé un moteur à combustion interne de véhicules automobiles. Les dispositifs de supports moteurs sont connus de l'art antérieur ; à titre d'exemple, les documents EP1692385 ET EP0989294 pet) )nt illustrer plusieurs manières de réaliser de tels dispositifs. On retrouv i ment dans ces dispositifs un élément support moteur qui est destiné à titre fixé sur la partie haut moteur du moteur, c'est-à-dire sur au moins la culasse, ou bien sur un ensemble de culasse qui comporte au moins une culasse et sur laquelle peut être rapporté un couvre-culasse. On retrouve également une coiffe moteur qui est fixée sur le moteur selon divers mode : soit intégrée à l'élément de support moteur lors de la fabrication par moulage de ce dernier (EP1692385), soit fixée sur le moteur en prenant en sandwich une partie de l'élément support moteur (EP0989294). The present invention relates to a motor support device for equipped with an internal combustion engine of motor vehicles. Motor support devices are known from the prior art; for example, the documents EP1692385 and EP0989294 pet)) nt illustrate several ways of making such devices. In these devices there is found a motor support element which is intended as a fixed part on the high engine part of the engine, that is to say on at least the cylinder head, or on a cylinder head assembly which comprises at least one breech and on which can be reported a cylinder head cover. There is also an engine cover that is fixed to the engine in various modes: either integrated with the engine support element during the manufacture by molding of the latter (EP1692385), is fixed to the engine by sandwiching a portion of the motor support element (EP0989294).
Un objectif commun aux dispositifs de support moteur est d'offrir une rigidité la plus importante possible. Cependant, il n'est pas toujours possible de réaliser les dispositifs décrits ci-dessus, et il peut être nécessaire d'accroître encore plus leur rigidité. L'invention vise à pallier les inconvénients de l'état de la technique. Pour y parvenir, elle fournit un dispositif de support moteur du type décrit ci-dessus, et dans lequel la coiffe est directement fixée d'une part sur l'élément support moteur, et d'autre part sur la culasse. Mais d'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit. Pour sa compréhension, on se reportera aux figures suivantes : la figure 1 est une représentation schématique de l'élément support moteur et de la culasse la figure 2 est une représentation schématique de l'élément support moteur et de la coiffe moteur. A common goal of the engine support devices is to provide the greatest possible rigidity. However, it is not always possible to achieve the devices described above, and it may be necessary to further increase their rigidity. The invention aims to overcome the disadvantages of the state of the art. To achieve this, it provides a motor support device of the type described above, and wherein the cap is directly fixed on the one hand on the motor support member, and on the other hand on the cylinder head. But other features and advantages of the invention will appear on reading the detailed description which follows. For its understanding, reference will be made to the following figures: FIG. 1 is a schematic representation of the engine support element and the cylinder head FIG. 2 is a schematic representation of the engine support element and the engine hood.
En référence à la figure 2, la coiffe moteur 10 est une pièce, de préférence en matière métallique, qui est destinée à former partie du bras de liaison entre le moteur et le châssis du véhicule. Selon l'invention, la coiffe moteur 10 vient se fixer directement d'une part sur l'élément support moteur 20 et d'autre part sur la culasse 30 du moteur (figure 1). C'est-à-dire qu'aucune pièce intermédiaire n'est disposée entre la coiffe 10 et la culasse 30, ou la coiffe 10 et l'élément support moteur 20. La coiffe moteur 10 est prévue pour être fixée directement à l'aide de vis sur l'élément support moteur 20 et la culasse 30. Selon un aspect complémentaire de l'invention représenté partiellement à la figure 2, la coiffe moteur 10 définit deux surfaces d'appui qui sont sensiblement parallèles, aux intervalles de tolérances près. Parmi ces surfaces, on compte une première surface d'appui 11 qui vient contre l'élément support moteur 20, et une deuxième surface d'appui 12 qui vient contre la culasse 30. L'élément support moteur 20 est une pièce, généralement en matière métallique, qui vient se fixer à une extrémité longitudinale de la culasse 30. Cet élément support moteur 20 est en liaison avec la culasse 30 du moteur (ou plus généralement le haut moteur), la coiffe moteur 10, et dans le cas où celle-ci est présente, une biellette (non représentée). L'élément support moteur 20 peut également servir de partie de capotage, et participer à la protection d'éléments tournants du moteur. Referring to Figure 2, the motor cap 10 is a part, preferably of metal material, which is intended to form part of the connecting arm between the engine and the chassis of the vehicle. According to the invention, the motor cap 10 is fixed directly on the one hand on the motor support element 20 and on the other hand on the cylinder head 30 of the engine (Figure 1). That is to say that no intermediate piece is disposed between the cap 10 and the cylinder head 30, or the cap 10 and the motor support member 20. The motor cap 10 is provided to be fixed directly to the With a further aspect of the invention shown partially in FIG. 2, the motor cap 10 defines two bearing surfaces which are substantially parallel, at tolerance intervals close to one another. . Among these surfaces, there is a first bearing surface 11 which comes against the motor support element 20, and a second bearing surface 12 which comes against the cylinder head 30. The engine support element 20 is a part, generally made of metal material, which is attached to a longitudinal end of the cylinder head 30. This engine support element 20 is in connection with the cylinder head 30 of the engine (or more generally the high engine), the engine cap 10, and in the case where that Here is present, a rod (not shown). The motor support element 20 can also serve as a cowling part, and participate in the protection of rotating elements of the engine.
L'élément support moteur 20 se fixe sur la culasse par l'intermédiaire de vis (non représentées). Au moins autour des trous 27 recevant les vis de fixation, se trouvent des portions de surfaces 28 usinées dans un même plan, de manière à former la face d'appui qui vient en contact avec l'extrémité longitudinale de la culasse 30. The motor support element 20 is fixed on the cylinder head by means of screws (not shown). At least around the holes 27 receiving the fixing screws, there are portions of surfaces 28 machined in the same plane, so as to form the bearing face which comes into contact with the longitudinal end of the yoke 30.
L'élément support moteur 20 définit une première surface de réception 21 de la première surface d'appui 11 de la coiffe moteur 10. Pour assurer un bon montage entre l'élément support moteur 20, la coiffe 10 et la culasse 30, l'élément support moteur 20 vient se positionner, se centrer sur la culasse 30. Selon un aspect complémentaire de l'invention, afin d'améliorer considérablement le centrage de l'élément support moteur 20 sur la culasse 30, l'élément support moteur 20 définit au moins une troisième surface d'appui 23 sur la culasse 30, cette surface 23 étant sensiblement orthogonale à la face d'appui contre la culasse 30. Lors du montage, l'élément support moteur 20 est ainsi en butée selon l'axe longitudinale de la culasse et aussi selon un axe dit ertical V. Cette troisième surface 23 peut être sensiblement parallèle à la pre....ere surface d'appui 21 de l'élément support moteur 20. Selon le mode de réalisation représenté à la figure 2, l'élément support moteur 20 définit au moins une troisième 23 et une quatrième 24 surface d'appui sur la culasse 30 qui sont disposées de part et d'autre de l'axe dit vertical V de l'élément support moteur 20. Ces surfaces 23 et 24 sont éloignées l'une de l'autre, et sont également éloignées de l'axe V, de sorte que, lors du montage, l'élément support moteur 20, se tienne de lui-même sur la culasse, par son propre poids. The motor support element 20 defines a first receiving surface 21 of the first bearing surface 11 of the motor cover 10. To ensure a good fit between the motor support element 20, the cap 10 and the cylinder head 30, the motor support element 20 is positioned, center on the cylinder head 30. According to a complementary aspect of the invention, in order to significantly improve the centering of the engine support element 20 on the cylinder head 30, the engine support element 20 defines at least one third bearing surface 23 on the yoke 30, this surface 23 being substantially orthogonal to the bearing face against the yoke 30. During assembly, the motor support member 20 is thus abutted along the longitudinal axis of the yoke and also according to a so-called vertical axis V. This third surface 23 may be substantially parallel to the pre .... bearing surface 21 of the motor support element 20. According to the embodiment shown in FIG. 2, the el motor support 20 defines at least a third 23 and a fourth support surface 24 on the cylinder head 30 which are disposed on either side of the so-called vertical axis V of the motor support element 20. These surfaces 23 and 24 are spaced from each other, and are also remote from the axis V, so that, during assembly, the motor support member 20, is self-standing on the cylinder head, by its own weight .
Les troisième 23 et quatrième 24 surfaces d'appui de l'élément support moteur 20 peuvent être définies chacune sous une protubérance 25, 26 en saillie par rapport à la face d'appui de l'élément support moteur 20 contre la culasse 30, c'est-à-dire au plan de contact entre l'élément support moteur 20 et l'extrémité longitudinale de la culasse 30. Elles peuvent être obtenues, de manière préférentielle, par usinage, La culasse 30 doit être comprise, dans le cadre de l'invention, comme étant une culasse seule, ou comme étant un ensemble de culasse qui peut alors comporter une culasse sur laquelle peut être monté un couvre-culasse. IO La culasse 30 possède une forme globalement parallélépipédique. La face de l'une de ses extrémités longitudinale est usinée de manière à recevoir la face correspondante de l'élément support moteur 20, qui est décrite ci-dessus. Conformément à l'invention, la culasse 30 définie une deuxième surface de réception 32 de la deuxième surface d'appui 12 de la coiffe moteur 10.The third 23 and fourth 24 bearing surfaces of the motor support member 20 may each be defined under a protuberance 25, 26 protruding from the bearing face of the motor support member 20 against the yoke 30, c that is to say at the plane of contact between the motor support element 20 and the longitudinal end of the cylinder head 30. They can be obtained, preferably, by machining, the cylinder head 30 must be included, in the context of the invention, as being a breech alone, or as being a breech assembly which can then include a breech on which can be mounted a cylinder head cover. The breech 30 has a generally parallelepipedic shape. The face of one of its longitudinal ends is machined to receive the corresponding face of the motor support member 20, which is described above. According to the invention, the yoke 30 defines a second receiving surface 32 of the second bearing surface 12 of the engine cap 10.
15 Pour se conformer au mode de réalisation de l'élément support moteur 20, la culasse 30 peut également définir des troisième 33 et quatrième 34 surfaces de réception des troisième 23 et quatrième 24 surfaces d'appui de l'élément support moteur 20. Sur la figure 1, la protubérance 26 et sa quatrième surface d'appui 24 ont été volontairement omises pour représenter plus facilement la 20 ième surface de réception 34 de la culasse 30. Ces surfaces sont usinées. ; peuvent être sensiblement parallèles à la deuxième surface de réception 32 'e la culasse 30. L'avantage, dans le cas où toutes les surfaces d'appui et de réception présentées ci-dessus sont parallèles entre elles, est que la maîtrise des tolérances est bien plus importante, ce qui permet de garantir une rigidité 25 maximale de l'assemblagei En effet, grâce aux troisième et quatrième surfaces d'appuis qui viennent se poser sur les troisième et quatrième surfaces de réception de la culasse, la coiffe moteur est reçue parfaitement sur l'élément de support moteur et sur la culasse, Le dispositif de support moteur permet ainsi d'obtenir un assemblage d'une 30 très grande rigidité, tout en ayant un nombre de pièce limité et un nombre de vis réduit. De plus le montage de l'élément support moteur sur la culasse est amélioré, ce qui facilite les opérations d'assemblage en usine. In order to comply with the embodiment of the motor support member 20, the yoke 30 may also define third 33 and fourth 34 receiving surfaces of the third 23 and fourth 24 bearing surfaces of the motor support member 20. 1, the protuberance 26 and its fourth bearing surface 24 have been intentionally omitted to more easily represent the 20 th receiving surface 34 of the cylinder head 30. These surfaces are machined. ; may be substantially parallel to the second receiving surface 32 'e the cylinder head 30. The advantage, in the case where all bearing surfaces and reception presented above are parallel to each other, is that the control of tolerances is much more important, which ensures maximum rigidity of the assemblyi Indeed, thanks to the third and fourth bearing surfaces that come to rest on the third and fourth receiving surfaces of the cylinder head, the motor cap is received The engine support device thus makes it possible to obtain an assembly of very high rigidity, while having a limited number of parts and a reduced number of screws. In addition, the mounting of the engine support element on the cylinder head is improved, which facilitates assembly operations at the factory.
