L'étape de fixation du groupe motopropulseur sur le châssis via le dispositif de fixation peut comprendre une étape de fixation, notamment de vissage, du dispositif de fixation sur un élément de fixation du groupe motopropulseur ou du châssis, notamment sur un goujon de l'élément de fixation du groupe motopropulseur ou du châssis. L'étape de fixation du dispositif de fixation sur un élément de fixation du groupe motopropulseur peut comprendre une étape de mise en place du dispositif de fixation par déplacement de celui-ci selon une direction parallèle ou sensiblement parallèle à la direction du déplacement du groupe motopropulseur relativement au châssis.

The method may then comprise a step of removing the fixing device and a step of fixing the power unit on the chassis without the fixing device.
Selon l'invention, un véhicule automobile est obtenu par le procédé défini précédemment. According to the invention, a motor vehicle is obtained by the method defined above.
Le dessin annexé représente, à titre d'exemple, un mode de réalisation d'un dispositif de fixation selon l'invention. The attached drawing shows, by way of example, an embodiment of a fixing device according to the invention.
La figure 1 est une vue d'un groupe motopropulseur monté sur un châssis d'un véhicule automobile dans une première configuration. La figure 2 est une vue du groupe motopropulseur monté sur le châssis d'un véhicule automobile dans une deuxième configuration à l'aide d'un mode de réalisation d'un dispositif de fixation selon l'invention. La figure 3 est une vue en perspective du mode de réalisation du dispositif de fixation selon l'invention. Figure 1 is a view of a powertrain mounted on a chassis of a motor vehicle in a first configuration. FIG. 2 is a view of the powertrain mounted on the chassis of a motor vehicle in a second configuration using an embodiment of a fastening device according to the invention. Figure 3 is a perspective view of the embodiment of the fastening device according to the invention.
La figure 4 est une vue de détail, dans la deuxième configuration, du mode de réalisation du dispositif de fixation selon l'invention, mis en place sur un groupe motopropulseur avant fixation au châssis. FIG. 4 is a detail view, in the second configuration, of the embodiment of the fixing device according to the invention, placed on a powertrain before attachment to the chassis.
La figure 5 est une vue de détail, dans la deuxième configuration, du mode de réalisation du dispositif de fixation selon l'invention, mis en place entre un groupe motopropulseur et un châssis, le groupe motopropulseur étant fixé au châssis via le dispositif de fixation. FIG. 5 is a detailed view, in the second configuration, of the embodiment of the fixing device according to the invention, placed between a powertrain and a chassis, the powertrain being fixed to the chassis via the fixing device. .
Sur la figure 1 , une partie de véhicule automobile est représentée. Le véhicule comprend un châssis 2 et un groupe motopropulseur 1 . Le groupe motopropulseur comprend par exemple un moteur à combustion interne. Il pourrait cependant également comprendre un moteur électrique. In Figure 1, a motor vehicle part is shown. The vehicle includes a chassis 2 and a power train 1. The powertrain includes for example an internal combustion engine. It could however also include an electric motor.
Le groupe motopropulseur est fixé au châssis grâce à des éléments de fixation 3 du châssis prévus sur le châssis, comme des bras ou des pattes, coopérant avec des éléments de fixation 4 du groupe motopropulseur, comme des bras ou des pattes. Par exemple, à l'extrémité des éléments de fixation du groupe motopropulseur, des goujons 7 sont mis en place. Une fois le groupe motopropulseur positionné relativement au châssis, ces goujons traversent l'extrémité des éléments de fixation du châssis et des écrous 9 sont mis en place sur les goujons. De préférence, les goujons traversent les éléments de fixation du châssis au niveau d'organes amortisseurs 8, comme des silentblocs, afin d'assurer un découplage vibratoire maximal entre le groupe motopropulseur et le châssis. Bien entendu, la fixation pourrait être inversée. Notamment, les goujons pourraient être mis en place sur les éléments de fixation du châssis pour venir coopérer avec des trous de passage prévus dans les éléments de fixation du groupe motopropulseur. The powertrain is fixed to the chassis by means of fasteners 3 of the frame provided on the chassis, such as arms or lugs, cooperating with fasteners 4 of the powertrain, such as arms or lugs. For example, at the end of the fasteners of the powertrain, studs 7 are put in place. Once the powertrain is positioned relative to the chassis, these studs pass through the end of the frame fasteners and nuts 9 are placed on the studs. Preferably, the studs pass through the fastening elements of the frame at damping members 8, such as silentblocs, to ensure decoupling vibration between the powertrain and the chassis. Of course, the attachment could be reversed. In particular, the studs could be put in place on the fastening elements of the chassis to cooperate with passage holes provided in the fasteners of the powertrain.
Par exemple, on utilise deux éléments de fixation du châssis coopérant avec deux éléments de fixation du groupe motopropulseur pour fixer ou suspendre le groupe motopropulseur sur le châssis. Cependant, on peut bien sûr utiliser plus de deux éléments de fixation du châssis coopérant avec plus de deux éléments de fixation du groupe motopropulseur. For example, two chassis attachment elements cooperating with two powertrain fastening elements are used to fix or suspend the powertrain on the chassis. However, it is of course possible to use more than two chassis fasteners cooperating with more than two fasteners of the powertrain.
Sur la figure 1 , le groupe motopropulseur se trouve dans une première configuration caractérisée par une première position du groupe motopropulseur relativement au châssis. In Figure 1, the powertrain is in a first configuration characterized by a first position of the powertrain relative to the chassis.
Comme évoqué précédemment, dans cette première position, certaines opérations de maintenance ou de service après-vente sont délicates, voire impossibles. Il est donc nécessaire de démonter le groupe motopropulseur relativement du châssis pour faciliter, voire pour rendre réalisables, certaines opérations. Pour rendre possible le fonctionnement du groupe motopropulseur alors que celui-ci ne se trouve pas dans la première position décrite précédemment, on utilise des dispositifs de fixation objets de l'invention. As mentioned above, in this first position, certain maintenance or after-sales service operations are delicate, if not impossible. It is therefore necessary to disassemble the powertrain relative to the chassis to facilitate, or to make achievable, certain operations. To make possible the operation of the powertrain when it is not in the first position described above, fastening devices object of the invention are used.
En effet, les dispositifs de fixation selon l'invention permettent de réaliser une interface de fixation mécanique entre les éléments de fixation du groupe motopropulseur et les éléments de fixation du châssis, de sorte que le groupe motopropulseur soit fixé au châssis dans une deuxième configuration caractérisée par une deuxième position du groupe motopropulseur relativement au châssis. Pour réaliser cette interface, on fixe une première extrémité de chaque dispositif de fixation aux éléments de fixation du groupe motopropulseur et on fixe une deuxième extrémité de chaque dispositif de fixation aux éléments de fixation du châssis. On se retrouve alors dans la deuxième configuration représentée aux figures 2 et 5. La figure 4 représente la même deuxième configuration avant fixation des dispositifs de fixation aux éléments de fixation du châssis. Ainsi, le dispositif 5 de fixation permet de fixer le groupe motopropulseur 1 sur le châssis 2 du véhicule automobile, dans la deuxième configuration. Le dispositif de fixation comprend un corps dont une première extrémité 57 est destinée à être liée ou fixée à un premier élément 4 de fixation du groupe motopropulseur et dont une deuxième extrémité 58 est destinée à être liée ou fixée à un deuxième élément 3 de fixation du châssis. Néanmoins, hors opérations de service après-vente ou de maintenance, il est clair que le premier élément de fixation du groupe motopropulseur est fixé au deuxième élément de fixation du châssis de manière directe ou tout au moins sans l'utilisation du dispositif 5 de fixation, de sorte que le groupe motopropulseur soit fixé au châssis dans la première configuration. In fact, the fastening devices according to the invention make it possible to provide a mechanical fastening interface between the powertrain fastening elements and the chassis fastening elements, so that the powertrain is fixed to the chassis in a second configuration characterized by a second powertrain position relative to the chassis. To achieve this interface, a first end of each fastening device is fixed to the fastening elements of the powertrain and a second end of each fastening device is attached to the fastening elements of the chassis. We then find ourselves in the second configuration shown in Figures 2 and 5. Figure 4 shows the same second configuration before fixing the fasteners to the frame fasteners. Thus, the fixing device 5 makes it possible to fix the power unit 1 on the chassis 2 of the motor vehicle, in the second configuration. The fixing device comprises a body of which a first end 57 is intended to be linked or fixed to a first element 4 for fixing the powertrain and a second end 58 of which is intended to be connected or fixed to a second fixing element 3 of the frame. Nevertheless, apart from service or maintenance operations, it is clear that the first attachment element of the powertrain is attached to the second frame fastener element directly or at least without the use of the fixing device 5 , so that the powertrain is attached to the chassis in the first configuration.
Dans un mode de réalisation représenté à la figure 3, le dispositif de fixation a une forme allongée selon un axe 56. Par exemple, il mesure entre 10 cm et 20 cm, notamment environ 15 cm. In one embodiment shown in Figure 3, the fixing device has an elongated shape along an axis 56. For example, it measures between 10 cm and 20 cm, in particular about 15 cm.
Le dispositif de fixation a par exemple une forme globale de révolution. Il est constitué d'une première partie 52 alésée s'étendant depuis sa première extrémité 57 et une deuxième partie 54 taraudée s'étendant depuis sa deuxième extrémité 58. Sa première extrémité 57 comprend une face 51 destinée à venir en appui contre l'élément de fixation du groupe motopropulseur. À sa deuxième extrémité 58, le dispositif de fixation comprend un taraudage 55, par exemple un taraudage M10, suivant l'axe 56. Par ailleurs, la première partie comprend une entaille 53 ou une rainure s'étendant radialement depuis l'axe 56. Comme il sera décrit plus loin, cette entaille permet de faire coïncider l'axe 56 du dispositif de fixation et l'axe 71 d'un goujon 7 en déplaçant le dispositif de fixation essentiellement perpendiculairement à son axe 56. La hauteur de vantail mesuré selon l'axe 56 est néanmoins inférieure à la hauteur du goujon 7 mesuré selon l'axe 71 , de sorte que l'extrémité filetée du goujon puisse être vissée dans le taraudage 55. The fixing device has for example a global form of revolution. It consists of a first bore portion 52 extending from its first end 57 and a second threaded portion 54 extending from its second end 58. Its first end 57 comprises a face 51 intended to bear against the element. powertrain fastening. At its second end 58, the fixing device comprises a tapping 55, for example a tapping M10, along the axis 56. Furthermore, the first part comprises a notch 53 or a groove extending radially from the axis 56. As will be described later, this notch allows to make the axis 56 of the fastening device coincide with the axis 71 of a stud 7 by moving the fixing device substantially perpendicular to its axis 56. The height of the leaf measured along the axis 56 is nevertheless less than the height the stud 7 measured along the axis 71, so that the threaded end of the stud can be screwed into the tapping 55.
Le taraudage permet de recevoir un premier élément fileté de fixation 6, comme une vis coopérant avec le deuxième élément de fixation du châssis. Le premier élément fileté traverse par exemple un trou prévu sur le deuxième élément de fixation du châssis. Il peut également permettre de recevoir un deuxième élément fileté de fixation, comme un goujon 7, solidaire du groupe motopropulseur. Alternativement, deux taraudages peuvent être prévus pour recevoir les premier et deuxième éléments filetés. The tapping makes it possible to receive a first threaded fastener element 6, such as a screw cooperating with the second fastener element of the chassis. The first threaded element passes through, for example, a hole provided on the second element for fixing the frame. It may also allow to receive a second threaded fastener element, such as a stud 7, integral with the powertrain. Alternatively, two threads may be provided to receive the first and second threaded elements.
Le dispositif de fixation 5 constitue avec l'élément fileté 6 un ensemble de fixation. The fastening device 5 constitutes with the threaded element 6 a fixing assembly.
Un mode de réalisation d'un procédé de modification de la fixation d'un groupe motopropulseur sur un châssis d'un véhicule automobile est décrit ci- après. Cette modification permet de faire passer un groupe motopropulseur de la première configuration à la deuxième configuration. Pour ce faire, on agit sur la suspension du groupe motopropulseur relativement au châssis. One embodiment of a method of modifying the attachment of a power unit to a chassis of a motor vehicle is described below. This change allows a powertrain to be passed from the first configuration to the second configuration. To do this, we act on the suspension of the powertrain relative to the chassis.
Ainsi, dans une première étape, on amène une table élévatrice sous le groupe motopropulseur et on désolidarise le groupe motopropulseur du châssis au niveau des fixations évoquées précédemment. Le châssis reposant sur un pont élévateur, on le déplace, par exemple on le remonte, par exemple de 15 cm. Thus, in a first step, a lifting table is brought under the powertrain and the power unit is detached from the chassis at the previously mentioned fixations. The chassis resting on a lift, it is moved, for example it goes up, for example 15 cm.
Dans une deuxième étape, on fournit et on met en place des dispositifs de fixation 5. Dans l'exemple représenté, on fait coïncider l'axe 56 du dispositif de fixation et l'axe 71 d'un goujon 7 et on amène l'extrémité du taraudage 55 au fond de l'alésage 59 en contact avec l'extrémité du goujon 7 en déplaçant le dispositif de fixation essentiellement perpendiculairement à son axe 56. En effet, du fait de la présence d'un élément de fixation du châssis, il n'est pas possible de mettre en place le dispositif de fixation en déplaçant le dispositif de fixation essentiellement parallèlement à son axe 56 pour amener l'extrémité du taraudage 55 au fond de l'alésage 59 en contact avec l'extrémité du goujon 7. On visse ensuite les dispositifs de fixation sur les goujons jusqu'à ce que les surfaces 51 arrivent en contact contre les éléments de fixation du groupe motopropulseur. In a second step, we provide and set up fasteners 5. In the example shown, is made to coincide the axis 56 of the fixing device and the axis 71 of a stud 7 and brings the end of the tapping 55 at the bottom of the bore 59 in contact with the end of the stud 7 by moving the fixing device substantially perpendicularly to its axis 56. Indeed, due to the presence of a frame fastener element, it is not possible to set up the fixing device by moving the fixing device substantially parallel to its axis 56 to bring the end of the tapping 55 to the bottom of the bore 59 in contact with the end of the stud 7 The fasteners are then screwed onto the studs until the surfaces 51 come into contact with the powertrain fasteners.
Dans une troisième étape, on fixe le groupe motopropulseur sur le châssis via le dispositif de fixation. Pour ce faire, on fournit des vis 6 et on les met en place dans des trous pratiqués dans les éléments de fixation du châssis (dans lesquels pénètrent normalement les goujons 7). Puis, on visse ces vis 6 dans les taraudages 55 comme représenté à la figure 5. Ainsi, les dispositifs de fixation se retrouvent intercalés entre les éléments de fixation du groupe motopropulseur et les éléments de fixation du châssis. Ils permettent de fixer le groupe motopropulseur dans sa deuxième configuration. En effet, les efforts de retenue ou de suspension du groupe motopropulseur passent des goujons 7 aux dispositifs de fixation, puis aux vis 6, puis aux éléments de fixation du châssis. In a third step, the powertrain is fixed on the chassis via the fixing device. To do this, screws 6 are provided and they are put in place in holes made in the frame fastening elements (in which the studs 7 normally penetrate). Then, these screws 6 are screwed into the threads 55 as shown in FIG. 5. Thus, the fasteners are interposed between the fastening elements of the powertrain and the fastening elements of the chassis. They allow to fix the powertrain in its second configuration. Indeed, the forces of restraint or suspension of the powertrain pass studs 7 to the fasteners, then to the screws 6, and then to the fasteners of the chassis.
Le groupe motopropulseur est alors suspendu au châssis grâce au dispositif de fixation jouant le rôle de rallonge. Dès lors, on peut effectuer des opérations de maintenance ou de service après-vente sur le groupe motopropulseur. On peut même si besoin faire fonctionner le groupe motopropulseur alors qu'il se trouve dans sa deuxième configuration pour vérifier que tout fonctionne correctement avant de faire repasser le groupe motopropulseur dans sa première configuration en procédant à l'inverse de ce qui a été décrit plus haut. The powertrain is then suspended from the chassis with the attachment device acting as an extension. Therefore, we can carry out maintenance or after-sales service on the powertrain. If necessary, the powertrain can be operated while it is in its second configuration to check that everything is working properly before returning the power train to its first configuration by doing the opposite of what has been described more. high.
Une fois ces vérifications faites et le groupe motopropulseur reconfiguré dans sa première configuration, le véhicule automobile peut être rendu à son propriétaire. Once these checks are made and the power train reconfigured in its first configuration, the motor vehicle can be returned to its owner.
De préférence, on utilise des dispositifs de fixation ayant une longueur d'environ 15 cm. Comme vu précédemment, l'utilisation d'une entaille 53 permet de limiter les déplacements du châssis par rapport au moteur lors du passage de la première configuration à la deuxième configuration. De plus, elle permet d'éviter de détériorer la partie filetée des goujons des éléments de fixation du groupe motopropulseur. Preferably, fasteners having a length of about 15 cm are used. As seen above, the use of a notch 53 makes it possible to limit the displacements of the chassis with respect to the engine during the passage from the first configuration to the second configuration. In addition, it avoids damaging the threaded portion of the studs of the powertrain fasteners.
