- Pins (or crimped screws) 49a extending perpendicularly to the front face 43b of the front portion 47a of the plate 40 make it possible to fix the CPU 1 and the DMTC 8 on the plate 40, which constitutes a contribution of rigidity to the plate 40 after tightening these elements.
- the front portion 47b comprises, in turn, a hole 48a for inserting the CPU 1.

- the plate 40 can be made of steel, for example with a shade
- Its thickness is generally between 1 mm and a few millimeters, for example close to 1.5 mm.
- it may comprise mechanical reinforcements 49b, for example made by stamping, to increase its rigidity.
- the assembly device also comprises at least one indexing pin 41 belonging to the support plate 40, at least one damping pad 42 intended to receive the indexing pin 41 and at least one an eyelet 31 belonging to the body structure 3, intended to receive the assembly formed by the pin 41 and the stud 42.
- the pin 41 is disposed on the rear portion 47a of the plate 40, and more specifically on an upper zone (not referenced) of this rear portion 47a.
- the rear portion 47a is intended to be inserted behind the front fender of the vehicle, in an area of the body structure 3 not very accessible for an operator involved in the assembly.
- the end zone (not referenced) of the rear portion 47a of the plate 40 is the least accessible for this operator.
- the implantation of the pin 41 in this area is therefore particularly advantageous to overcome the difficulties of accessibility and congestion encountered with existing assembly devices.
- the implantation of the pin 41 and the two lugs 44, 45 on the plate 40 is such that it prevents tilting of the assembly device supporting the assembly 10 about the axis X of the vehicle.
- the pin 41 is, moreover, fixed on the rear face 43a of the plate 40, this rear face 43a being the one that is intended to be placed opposite the body structure 3.
- the ears 44, 45 extend in a direction substantially perpendicular to said rear face 43a.
- the fixing of the pin 41 on the rear face 43a of the plate 40 is made by welding.
- the damping pad 42 has the shape of a double ring 42a, 42b, said rings being separated by a circumferential groove 42c, and traversed by an orifice 42d intended to receive the pin 41, as can be seen in FIGS. Figures 7 and 7bis.
- the two rings 42a, 42b have dimensions greater than those of the eyelet 31 so that the stud 42 can provide a blocking function of the assembly formed by the pin 41 and the stud 42 in the through eyelet 31.
- the stud 42 is made of an elastically deformable material.
- the upper ring 42b can return to its initial position.
- the lower ring 42a is, for its part, not brought to pass through the eyelet 31. Its diameter greater than that of the eyelet 31 thus makes it possible to form a stop, when the operator inserts the pin 41 in the stud 42 (the eyelet 31 being put in place before).
- the elastically deformable material forming the damping pad 42 is also capable of absorbing mechanical vibrations.
- damping pad 42 An example of a suitable material for the damping pad 42 is, for example, an elastomer such as rubber.
- the eyelet 31 of the body structure 3 can be made in an ear 32 belonging to the body structure 3. This ear 32 then extends substantially perpendicularly to a main face 33 of said body structure 3.
- the parts 1, 2, 8 of the set 10 "START and STOP" are previously mounted on the plate 40 before they arrive on the assembly line.
- the assembly of the assembly 10 on the body structure 3 in the assembly line comprises two stages, the first consisting of inserting the damping pad 42 into the eyelet 31 of the body structure 3, then the inserting the pin 41 of the support plate 40 then supporting the CPU 1, the DMTC 8 and its cover 2 in the damping pad 42, which is already mounted.
- the operator therefore passes the assembly 10 mounted on the plate 40 under the front left wing 20 of the vehicle.
- the operator only has to fix the two ears 44, 45 of the plate on the body structure 3 by appropriate means, such as screw / nut assemblies. If screws are used, tightening them to the recommended torque is usually done at a next station on the assembly line.
- the operator receives a complete set (plate 40 + parts of the assembly 10) already mounted, which in itself saves time on the assembly line.
- guides arranged on the support plate 40 or on the body structure 3 facilitate this manipulation to the blind, also allowing to guarantee the games of proximity.
- the assembly (the connection) formed by the indexing pin 41 and the damping pad 42 is based on a much faster fixing method than the tightening of a screw / nut assembly, hence additional time saving in editing.
- damping pad 42 deformable material absorbs vibrations from the engine.
- additional mechanical reinforcements may be provided on the plate 40.

DISPOSITIF D'ASSEMBLAGE D'UN ENSEMBLE D'ARRET ET DE REDEMARRAGE AUTOMATIQUE D'UN MOTEUR DE VEHICULE SUR LA STRUCTURE DE CAISSE DEVICE FOR ASSEMBLING A STOP ASSEMBLY AND AUTOMATIC RESTART OF A VEHICLE ENGINE ON THE BODY STRUCTURE
DU VEHICULE ET PROCEDE D'ASSEMBLAGE ASSOCIE L'invention se rapporte à un dispositif d'assemblage d'un ensemble mettant en œuvre une fonction d'arrêt et de redémarrage automatique d'un moteur du véhicule sur la structure de caisse de ce véhicule. The invention relates to a device for assembling an assembly implementing a function of stopping and automatically restarting a vehicle engine on the body structure of this vehicle.
Elle se rapporte également à un procédé d'assemblage dudit ensemble sur la structure de caisse du véhicule. It also relates to a method of assembling said assembly on the body structure of the vehicle.
Un tel ensemble mettant en œuvre une fonction d'arrêt et de redémarrage automatique d'un moteur du véhicule est connu sous le nom de système « STOP and START », en terminologie anglo-saxonne. Such an assembly implementing a shutdown and automatic restart function of a vehicle engine is known as the system "STOP and START" in English terminology.
Les constructeurs automobiles ayant pour préoccupation la réduction des émissions de gaz à effet de serre en usage urbain ont développé cette fonction « STOP and START » qui consiste, dès l'arrêt du véhicule et/ou le passage au point mort, à provoquer automatiquement l'arrêt complet du moteur thermique lorsque le véhicule est lui-même à l'arrêt, puis à redémarrer automatiquement le moteur thermique à la suite, par exemple, d'une action du conducteur interprétée comme une demande de redémarrage. Car manufacturers concerned about the reduction of greenhouse gas emissions in urban use have developed this "STOP and START" function, which consists of automatically turning off the vehicle when the vehicle is stopped and / or stalled. complete shutdown of the engine when the vehicle itself is stopped, then restart automatically the engine after, for example, a driver action interpreted as a restart request.
Une situation typique de mise en œuvre de la fonction « STOP and A typical situation of implementation of the function "STOP and
START » est celle de l'arrêt du véhicule à un feu rouge. START "is that of stopping the vehicle at a red light.
Lorsque le conducteur arrête le véhicule au feu, le mode STOP provoque l'arrêt automatique du moteur thermique. When the driver stops the vehicle in fire, the STOP mode causes the automatic shutdown of the engine.
Puis, lorsque le conducteur souhaite repartir, le véhicule entre alors dans un mode de redémarrage automatique, ou mode START, dans lequel un redémarrage automatique du moteur thermique est effectué, sans qu'il soit nécessaire d'utiliser le moyen de démarrage initial du moteur, comme une clé de contact par exemple. Then, when the driver wishes to restart, the vehicle then enters an automatic restart mode, or START mode, in which an automatic restart of the engine is performed, without the need to use the initial engine starting means , like a contact key for example.
Le mode START permet de redémarrer automatiquement le moteur, notamment au moyen d'un alterno-démarreur, à la suite de la détection par le système de pilotage au démarrage du véhicule de l'enfoncement par le conducteur de la pédale d'embrayage, de la pédale d'accélérateur, ou encore de toute autre action pouvant être interprétée comme la volonté du conducteur de redémarrer son véhicule. The START mode is used to restart the engine automatically, in particular by means of an alternator-starter, following the detection by the control system when the vehicle is started of the depression by the driver of the clutch pedal, the accelerator pedal, or any other action that may be interpreted as the driver's desire to restart the vehicle.
Lors des phases d'arrêt du moteur, la consommation de carburant est stoppée, ce qui permet une économie de carburant substantielle. De plus, le véhicule n'émet alors aucun bruit, ce qui participe, en particulier en ville, à limiter la pollution sonore. Un dispositif d'assemblage connu d'un ensemble pour mettre en œuvre la fonction « STOP and START » sur une structure de caisse de véhicule est décrit à l'appui des figures 1 et 2. During engine shutdown phases, fuel consumption is halted, resulting in substantial fuel economy. In addition, the vehicle emits no noise, which helps, especially in the city, to limit noise pollution. A known assembly device of an assembly for implementing the "STOP and START" function on a vehicle body structure is described in support of FIGS. 1 and 2.
Un ensemble mettant en œuvre une fonction « STOP AND START » comprend une unité capacitaire 1 (ci-après nommé UC - voir figure 2) destinée à stocker de l'énergie électrique et un dispositif de maintien de tension et de commutation (ci-après nommé DMTC) dont le rôle est d'assurer la répartition de la puissance électrique logé sous un capot protecteur 2. Cet ensemble est associé à une machine électrique (non représentée) susceptible d'être configurée comme un moteur électrique pour lancer le démarrage du moteur thermique. An assembly implementing a "STOP AND START" function comprises a capacitor unit 1 (hereinafter named UC - see FIG. 2) intended to store electrical energy and a device for maintaining voltage and switching (hereinafter referred to as FIG. called DMTC) whose role is to ensure the distribution of the electrical power housed under a protective cover 2. This set is associated with an electric machine (not shown) that can be configured as an electric motor to start the engine start thermal.
Le compartiment moteur n'offre pas la place suffisante et l'accessibilité nécessaire pour y implanter l'ensemble des pièces de l'ensemble. Ainsi, les solutions connues implantent l'UC 1 , le DMTC et le capot protecteur 2 associé sous une aile avant du véhicule, de préférence sous l'aile avant gauche. Cet ensemble est alors fixé sur la structure de caisse 3 du véhicule au moyen d'une platine de support 4 sur laquelle tous les éléments de cet ensemble sont fixés. The engine compartment does not offer sufficient space and accessibility to install all parts of the set. Thus, the known solutions implant UC 1, the DMTC and the associated protective cover 2 under a front wing of the vehicle, preferably under the left front fender. This assembly is then fixed on the body structure 3 of the vehicle by means of a support plate 4 on which all the elements of this set are fixed.
La fixation de la platine de support 4 sur la structure de caisse 3 s'effectue grâce à une ou plusieurs oreilles 5 de fixation, appartenant à ladite platine de support 4, destinées à coopérer avec des éléments de vissage 6 de type vis/écrou. The mounting of the support plate 4 on the body structure 3 is effected by means of one or more attachment lugs 5 belonging to said support plate 4, intended to cooperate with screw / nut type screwing elements 6.
Cette solution présente plusieurs inconvénients. This solution has several disadvantages.
Un inconvénient est qu'elle est longue à mettre en œuvre sur une ligne de montage. A disadvantage is that it takes a long time to implement on an assembly line.
En effet, le montage est long du fait de la multiplicité des pièces à fixer ensemble, compte tenu du temps dédié à installer chacune de ces pièces sur la ligne de montage. Indeed, the assembly is long because of the multiplicity of parts to fix together, given the time dedicated to install each of these parts on the assembly line.
La productivité de la ligne de montage s'en trouve affectée. The productivity of the assembly line is affected.
Incidemment, cette solution accroît les difficultés pour une personne intervenant dans la maintenance du véhicule, au cours de la vie de ce dernier. Incidentally, this solution increases the difficulties for a person involved in the maintenance of the vehicle, during the life of the latter.
Un autre inconvénient réside dans le fait que, pour certaines catégories de véhicule, les ailes avant des véhicules sont assemblées sur la structure de caisse en atelier de ferrage pour diverses raisons, telles que la maîtrise des jeux et affleurements des différentes pièces à assembler ou la mise en peinture de la carosserie du véhicule. Another disadvantage lies in the fact that, for certain categories of vehicle, the front fenders of the vehicles are assembled on the body structure in the workshop for various reasons, such as the control of the games and outcrops of the various parts to be assembled or the painting the bodywork of the vehicle.
Dans ce cas, le montage de l'ensemble « STOP and START » sur la structure de caisse 3 avec la platine de support 4 devient impossible pour des raisons d'accessibilité, le vissage des éléments de vissage 6 sur les oreilles 5 de la platine de support 4 étant irréalisable. In this case, the assembly of the set "STOP and START" on the body structure 3 with the support plate 4 becomes impossible for reasons accessibility, the screwing of the screwing elements 6 on the ears 5 of the support plate 4 being unfeasible.
En effet, les oreilles 5 de la platine de support 4 sont disposées derrière le capot 2, lui-même disposé derrière l'aile. Indeed, the ears 5 of the support plate 4 are arranged behind the cover 2, itself arranged behind the wing.
Cette solution ne peut donc pas être envisagée pour ces catégories de véhicule. This solution can not be considered for these categories of vehicles.
La fixation de la platine de support 4 est cependant indispensable pour monter l'UC 1 , le DMTC et son capot 2 sur la structure de caisse 3. Fixing the support plate 4 is however essential to mount the CPU 1, the DMTC and its cover 2 on the body structure 3.
De plus, la fixation de la platine de support 4 en plusieurs points opposés de celle-ci sur la structure de caisse 3 présente plusieurs avantages. In addition, the fixing of the support plate 4 at several opposite points thereof on the body structure 3 has several advantages.
En effet, sans ces points de fixation, il existe un risque que la platine de support sur laquelle est montée l'ensemble « STOP and START » bascule autour de l'axe longitudinal X du véhicule comme illustré sur la figure 2. Or, un tel mouvement aurait pour conséquence grave la perte de la platine de support ou encore des dommages corporels pour l'homme. Indeed, without these attachment points, there is a risk that the support plate on which is mounted the assembly "STOP and START" tilts around the longitudinal axis X of the vehicle as shown in Figure 2. Now, a such movement would have the serious consequence of the loss of the support plate or the bodily injury to man.
Un autre inconvénient de cette solution est qu'elle transmet des vibrations vers l'ensemble « STOP and START », par l'intermédiaire des points de fixation de la platine de support 4 sur la structure de caisse 3 de véhicule, en l'occurrence formés par les oreilles 5 de la platine et les éléments de vissage 6. Another disadvantage of this solution is that it transmits vibrations towards the "STOP and START" assembly, via the fixing points of the support plate 4 on the vehicle body structure 3, in this case formed by the ears 5 of the plate and the screwing elements 6.
Un but de la présente invention est de proposer un dispositif d'assemblage palliant l'un au moins des inconvénients susmentionnés. An object of the present invention is to provide an assembly device that overcomes at least one of the aforementioned disadvantages.
En particulier, un but de la présente invention est de permettre le montage d'un ensemble « STOP and START » sous l'aile avant de n'importe quelle catégorie de véhicule après assemblage de celle-ci sur la structure de caisse du véhicule. In particular, an object of the present invention is to allow the assembly of a set "STOP and START" under the front wing of any vehicle category after assembly thereof on the body structure of the vehicle.
Un autre but de l'invention est de proposer un dispositif d'assemblage qui améliore la tenue en vibration de la platine de support d'un ensemble « STOP and START » montée sur une structure de caisse de véhicule. Another object of the invention is to provide an assembly device which improves the vibration resistance of the support plate of a set "STOP and START" mounted on a vehicle body structure.
Il est également désirable de proposer un dispositif d'assemblage dont le montage est simple et rapide à mettre en œuvre, diminuant ainsi les coûts de production. It is also desirable to provide an assembly device whose assembly is simple and quick to implement, thus reducing production costs.
A cet effet, on prévoit selon l'invention un dispositif d'assemblage d'un ensemble d'arrêt et de redémarrage automatique d'un moteur de véhicule sur une structure de caisse de véhicule, le dispositif comprenant une platine de support pour ledit ensemble, remarquable en ce que le dispositif comprend : For this purpose, there is provided according to the invention a device for assembling a stop assembly and automatic restart of a vehicle engine on a vehicle body structure, the device comprising a support plate for said assembly , remarkable in that the device comprises:

- au moins un plot d'amortissement destiné à être interposé entre ledit pion et ledit œillet. at least one damping pad intended to be interposed between said pin and said eyelet.

Dans le cadre de la présente invention, les termes « supérieur », « inférieur » et « avant », « arrière » associés au dispositif selon l'invention, s'entendent respectivement par rapport à la verticale et par rapport au sens d'avancement d'un véhicule, une fois que ce dispositif est monté sur la caisse de ce véhicule. In the context of the present invention, the terms "upper", "lower" and "front", "rear" associated with the device according to the invention are respectively relative to the vertical and with respect to the direction of advancement. of a vehicle, once this device is mounted on the body of this vehicle.
On a représenté, sur la figure 3(c), une structure latérale avant gauche d'un véhicule automobile, désignée par la référence générale 10. FIG. 3 (c) shows a front left side structure of a motor vehicle, designated by the general reference 10.
On observe l'aile avant gauche 20, prolongée à partir d'une portion supérieure de cette aile par un capot 21 . Cette aile avant gauche 20 est montée sur un support d'aile appartement à la structure de caisse 3, destiné à être fixé rigidement par une base à une poutre supérieure du châssis du véhicule. Elle est limitée par un passage 22 de roue destiné à recevoir la roue avant gauche. We observe the left front wing 20, extended from an upper portion of this wing by a hood 21. This left front wing 20 is mounted on a flat wing support to the body structure 3, intended to be rigidly fixed by a base to an upper beam of the vehicle chassis. It is limited by a wheel passage 22 for receiving the left front wheel.
Le dispositif d'assemblage pour un ensemble « STOP and START » selon l'invention est décrit ci-dessous, à l'appui des figures 3(a), 3(b), 4 à 8. The assembly device for a "STOP and START" assembly according to the invention is described below, in support of FIGS. 3 (a), 3 (b), 4 to 8.
Le dispositif d'assemblage comprend une platine de support 40 pour l'ensemble 10 « STOP and START », ce dernier comportant l'UC 1 , le DMTC 8 et le capot 2 pour protéger le DMTC. The assembly device comprises a support plate 40 for the assembly "STOP and START", the latter comprising the CPU 1, the DMTC 8 and the cover 2 to protect the DMTC.
La platine 40 formée d'une seule pièce comporte deux parties, à savoir une partie arrière 47a et une partie avant 47b. The plate 40 formed in one piece has two parts, namely a rear portion 47a and a front portion 47b.
La partie arrière 47a comprend une patte 48b qui permet le maintien du capot 2 de protection du DMTC 8 sur la platine de support 40, ainsi qu'un embouti 48c permettant la respiration d'une pastille en goretex située au dos du DMTC 8. The rear portion 47a comprises a tab 48b which allows the DMTC 8 protective cap 2 to be held on the support plate 40, as well as a stamp 48c allowing the breathing of a goretex chip located on the back of the DMTC 8.
Des picots (ou vis serties) 49a, s'étendant perpendiculairement à la face avant 43b de la partie avant 47a de la platine 40 permettent de fixer l'UC 1 et le DMTC 8 sur la platine 40, ce qui constitue un apport de rigidité à la platine 40 après serrage de ces éléments. Pins (or crimped screws) 49a, extending perpendicularly to the front face 43b of the front portion 47a of the plate 40 make it possible to fix the CPU 1 and the DMTC 8 on the plate 40, which constitutes a contribution of rigidity to the plate 40 after tightening these elements.
La partie avant 47b comprend, quant à elle, un trou 48a permettant d'insérer l'UC 1 . The front portion 47b comprises, in turn, a hole 48a for inserting the CPU 1.
La platine 40 comprend, également, au moins deux oreilles 44, 45 chacune munie d'un orifice pour des moyens de fixation avec la structure de caisse de véhicule 3. Ces moyens de fixation peuvent être de type vis/écrou. The plate 40 also comprises at least two lugs 44, 45 each provided with an orifice for fastening means with the vehicle body structure 3. These fastening means may be screw / nut type.
Plus précisément, la partie avant 47b de la platine comprend, au niveau d'une extrémité 46, l'une 45 des deux oreilles 44, 45 et la partie arrière 47a de la platine comprend, dans une zone inférieure (non référencée) de cette partie arrière 47a, l'autre 44 des deux oreilles 44, 45. Specifically, the front portion 47b of the plate comprises, at one end 46, one 45 of the two ears 44, 45 and the rear portion 47a of the plate comprises, in a lower zone (not referenced) of this rear portion 47a, the other 44 of the two ears 44, 45.
La platine 40 peut être réalisée en acier, par exemple avec une nuance The plate 40 can be made of steel, for example with a shade
ES. ES.
Son épaisseur est généralement comprise entre 1 mm et quelques millimètres, par exemple voisine de 1 ,5mm. Its thickness is generally between 1 mm and a few millimeters, for example close to 1.5 mm.
De plus, dans une variante de réalisation, elle peut comprendre des renforts mécaniques 49b, par exemple réalisés par emboutissage, pour augmenter sa rigidité. In addition, in an alternative embodiment, it may comprise mechanical reinforcements 49b, for example made by stamping, to increase its rigidity.
Selon l'invention, le dispositif d'assemblage comprend, également, au moins un pion d'indexation 41 appartenant à la platine de support 40, au moins un plot d'amortissement 42 destiné à recevoir le pion d'indexation 41 et au moins un œillet 31 appartenant à la structure de caisse 3, destiné à recevoir l'ensemble formé par le pion 41 et le plot 42. According to the invention, the assembly device also comprises at least one indexing pin 41 belonging to the support plate 40, at least one damping pad 42 intended to receive the indexing pin 41 and at least one an eyelet 31 belonging to the body structure 3, intended to receive the assembly formed by the pin 41 and the stud 42.
Le pion 41 est disposé sur la partie arrière 47a de la platine 40, et plus précisément sur une zone supérieure (non référencée) de cette partie arrière 47a. The pin 41 is disposed on the rear portion 47a of the plate 40, and more specifically on an upper zone (not referenced) of this rear portion 47a.
La partie arrière 47a est destinée à être insérée derrière l'aile avant du véhicule, dans une zone de la structure de caisse 3 peu accessible pour un opérateur intervenant dans le montage. The rear portion 47a is intended to be inserted behind the front fender of the vehicle, in an area of the body structure 3 not very accessible for an operator involved in the assembly.
En particulier, la zone d'extrémité (non référencée) de la partie arrière 47a de la platine 40 est la moins accessible pour cet opérateur. In particular, the end zone (not referenced) of the rear portion 47a of the plate 40 is the least accessible for this operator.
L'implantation du pion 41 dans cette zone est donc particulièrement avantageuse pour pallier les difficultés d'accessibilité et d'encombrement rencontrés avec les dispositifs d'assemblage existants. The implantation of the pin 41 in this area is therefore particularly advantageous to overcome the difficulties of accessibility and congestion encountered with existing assembly devices.
Par ailleurs, l'implantation du pion 41 et des deux oreilles 44, 45 sur la platine 40 est telle qu'elle évite tout basculement du dispositif d'assemblage supportant l'ensemble 10 autour de l'axe X du véhicule. Furthermore, the implantation of the pin 41 and the two lugs 44, 45 on the plate 40 is such that it prevents tilting of the assembly device supporting the assembly 10 about the axis X of the vehicle.
Le pion 41 est, par ailleurs, fixé sur la face arrière 43a de la platine 40, cette face arrière 43a étant celle qui est destinée à être mise en vis-à-vis de la structure de caisse 3. The pin 41 is, moreover, fixed on the rear face 43a of the plate 40, this rear face 43a being the one that is intended to be placed opposite the body structure 3.
Il faut noter que c'est à partir de cette face arrière 43a de la platine 40 que s'étendent les oreilles 44, 45, selon une direction sensiblement perpendiculaire à ladite face arrière 43a. Avantageusement, la fixation du pion 41 sur la face arrière 43a de la platine 40 est réalisée par soudage. It should be noted that it is from this rear face 43a of the plate 40 that the ears 44, 45 extend in a direction substantially perpendicular to said rear face 43a. Advantageously, the fixing of the pin 41 on the rear face 43a of the plate 40 is made by welding.
Concernant le plot d'amortissement 42, ce dernier présente la forme d'une double couronne 42a, 42b, lesdites couronnes étant séparées par une rainure circonférentielle 42c, et traversées par un orifice 42d destiné à recevoir le pion 41 , comme cela est visible aux figures 7 et 7bis. Concerning the damping pad 42, the latter has the shape of a double ring 42a, 42b, said rings being separated by a circumferential groove 42c, and traversed by an orifice 42d intended to receive the pin 41, as can be seen in FIGS. Figures 7 and 7bis.
Les deux couronnes 42a, 42b présentent des dimensions supérieures à celles de l'oeillet 31 de sorte que le plot 42 puisse assurer une fonction de blocage de l'ensemble formé par le pion 41 et le plot 42 dans l'oeillet traversant 31 . The two rings 42a, 42b have dimensions greater than those of the eyelet 31 so that the stud 42 can provide a blocking function of the assembly formed by the pin 41 and the stud 42 in the through eyelet 31.
Pour s'assurer du passage de la couronne 42b, dite couronne supérieure, dans l'oeillet 31 , le plot 42 est en un matériau déformable élastiquement. To ensure the passage of the crown 42b, said upper ring, in the eyelet 31, the stud 42 is made of an elastically deformable material.
Ainsi, après être passé dans l'oeillet 31 en se déformant (le passage s'effectue en force sous l'action de l'opérateur), la couronne supérieure 42b peut revenir dans sa position initiale. Thus, after having passed through the eyelet 31 by deforming (the passage is made in force under the action of the operator), the upper ring 42b can return to its initial position.
Son diamètre plus grand que celui de l'oeillet 31 empêche tout mouvement inverse en l'absence d'action spécifique. Its diameter greater than that of the eyelet 31 prevents any reverse movement in the absence of specific action.
La couronne inférieure 42a n'est, quant à elle, pas amenée à traverser l'oeillet 31 . Son diamètre plus grand que celui de l'oeillet 31 permet ainsi de former une butée, lorsque l'opérateur insère le pion 41 dans le plot 42 (l'oeillet 31 étant mis en place auparavant). The lower ring 42a is, for its part, not brought to pass through the eyelet 31. Its diameter greater than that of the eyelet 31 thus makes it possible to form a stop, when the operator inserts the pin 41 in the stud 42 (the eyelet 31 being put in place before).
Avantageusement, le matériau déformable élastiquement formant le plot d'amortissement 42 est également capable d'absorber des vibrations mécaniques. Advantageously, the elastically deformable material forming the damping pad 42 is also capable of absorbing mechanical vibrations.
Un tel matériau permet alors d'absorber les vibrations provenant du moteur. On limite ainsi la transmission de vibrations vers l'ensemble 10 « START and STOP » et on améliore la tenue en roulage de l'ensemble 10 monté sur la strcuture de caisse du véhicule Such a material then makes it possible to absorb the vibrations coming from the engine. This limits the transmission of vibrations to the assembly "START and STOP" and improves the rolling behavior of the assembly 10 mounted on the bodywork of the vehicle body
Un exemple de matériau susceptible de convenir pour le plot d'amortissement 42 est, par exemple , un élastomère tel que du caoutchouc. An example of a suitable material for the damping pad 42 is, for example, an elastomer such as rubber.
L'oeillet 31 de la structure de caisse 3 peut être réalisé dans une oreille 32 appartenant à la structure de caisse 3. Cette oreille 32 s'étend alors sensiblement perpendiculairement à une face principale 33 de ladite structure de caisse 3. The eyelet 31 of the body structure 3 can be made in an ear 32 belonging to the body structure 3. This ear 32 then extends substantially perpendicularly to a main face 33 of said body structure 3.
Un procédé de montage de l'ensemble 10 « START and STOP » mis en œuvre avec le dispositif d'assemblage susmentionné est le suivant. One method of mounting the "START and STOP" assembly implemented with the above-mentioned assembly device is as follows.
Les pièces 1 , 2, 8 de l'ensemble 10 « START and STOP » sont montées préalablement sur la platine 40 avant qu'elles n'arrivent sur la chaîne de montage. Ainsi, l'assemblage de l'ensemble 10 sur la structure de caisse 3 en chaîne de montage comprend deux étapes, la première consistant à insérer le plot d'amortissement 42 dans l'œillet 31 de la structure de caisse 3, puis l'insertion du pion 41 de la platine de support 40 supportant alors l'UC 1 , le DMTC 8 et son capot 2 dans le plot d'amortissement 42 alors déjà monté. Lors de cette dernière étape, l'opérateur fait donc passer l'ensemble 10 monté sur la platine 40 sous l'aile 20 avant gauche du véhicule. The parts 1, 2, 8 of the set 10 "START and STOP" are previously mounted on the plate 40 before they arrive on the assembly line. Thus, the assembly of the assembly 10 on the body structure 3 in the assembly line comprises two stages, the first consisting of inserting the damping pad 42 into the eyelet 31 of the body structure 3, then the inserting the pin 41 of the support plate 40 then supporting the CPU 1, the DMTC 8 and its cover 2 in the damping pad 42, which is already mounted. During this last step, the operator therefore passes the assembly 10 mounted on the plate 40 under the front left wing 20 of the vehicle.
A l'issue de cette étape, l'opérateur n'a plus qu'à fixer les deux oreilles 44, 45 de la platine sur la structure de caisse 3 par des moyens appropriés, tels que des ensembles vis/écrou. Si des vis sont utilisées, le serrage de celles-ci au couple préconisé est généralement réalisé à un poste suivant sur la ligne de montage. At the end of this step, the operator only has to fix the two ears 44, 45 of the plate on the body structure 3 by appropriate means, such as screw / nut assemblies. If screws are used, tightening them to the recommended torque is usually done at a next station on the assembly line.
Il faut noter que ce procédé d'assemblage respecte intégralement l'objectif d'ergonomie pour l'opérateur en ligne de montage. It should be noted that this assembly process fully respects the goal of ergonomics for the online assembly operator.
En effet, l'opérateur reçoit un ensemble complet (platine 40 + pièces de l'ensemble 10) déjà monté, ce qui entraîne en soi un gain de temps sur la chaîne de montage. Indeed, the operator receives a complete set (plate 40 + parts of the assembly 10) already mounted, which in itself saves time on the assembly line.
Ce gain de temps est d'autant plus important que l'opérateur peut monter, grâce au dispositif d'assemblage selon l'invention, cet ensemble complet (platine 40 + pièces de l'ensemble 10) sur la structure de caisse 3 du véhicule à l'aveugle, sans difficulté. This time saving is all the more important that the operator can mount, thanks to the assembly device according to the invention, this complete assembly (plate 40 + parts of the assembly 10) on the body structure 3 of the vehicle blind, without difficulty.
Ceci est lié à la mise en œuvre d'un pion d'indexation 41 qui peut être aisément logé dans le plot d'amortissement 42 présent dans l'œillet 31 de la structure de caisse 3, sans voir la manipulation. This is related to the implementation of an indexing pin 41 which can be easily housed in the damping pad 42 present in the eyelet 31 of the body structure 3, without seeing the manipulation.
Avantageusement, des guides disposés sur la platine de support 40 ou sur la structure de caisse 3 (au niveau de l'oreille 32) facilitent cette manipulation à l'aveugle, en permettant également de garantir les jeux de proximité. Advantageously, guides arranged on the support plate 40 or on the body structure 3 (at the level of the ear 32) facilitate this manipulation to the blind, also allowing to guarantee the games of proximity.
Par ailleurs, l'ensemble (la liaison) formé par le pion d'indexation 41 et le plot d'amortissement 42 s'appuie sur un mode de fixation beaucoup plus rapide que le serrage d'un ensemble vis/écrou, d'où un gain de temps supplémentaire dans le montage. Moreover, the assembly (the connection) formed by the indexing pin 41 and the damping pad 42 is based on a much faster fixing method than the tightening of a screw / nut assembly, hence additional time saving in editing.
De plus, l'existence d'une aile avant sur la structure de caisse du véhicule ne pose ainsi aucune difficulté au montage de l'ensemble 10 « START and STOP ». In addition, the existence of a front wing on the body structure of the vehicle does not pose any difficulty in assembling the assembly 10 "START and STOP".
Il est donc tout à fait envisageable de mettre en œuvre le dispositif d'assemblage selon l'invention sur des catégories de véhicules pour lesquelles cela n'était pas envisageable avec les dispositifs d'assemblage existants. Le coût lié à ce mode de fixation (pion 41 + plot 42 dans un œillet 31 de la structure de caisse 3) reste faible et tout à fait acceptable par rapport au coût d'un mode de fixation de type vis/écrou. It is therefore quite possible to implement the assembly device according to the invention on categories of vehicles for which this could not be envisaged with the existing assembly devices. The cost related to this method of attachment (pin 41 + stud 42 in a grommet 31 of the body structure 3) remains low and quite acceptable compared to the cost of a type of fastening type screw / nut.
En outre, le plot d'amortissement 42 en matériau déformable permet d'absorber les vibrations provenant du moteur. In addition, the damping pad 42 deformable material absorbs vibrations from the engine.
L'implantation du pion d'indexation 41 et des oreilles 44, 45 au sein de la platine 40 permettent d'obtenir une bonne robustesse de cette platine, en évitant des endommagements de type ER4 (il s'agit d'un événement redouté de gravité 4 qui est susceptible d'entraîner des dommages corporels pour l'homme, comme par exemple la perte de l'ensemble 10 entraînant une perte de contrôle du véhicule ou alors un impact sur le véhicule suivant). The implantation of the indexing pin 41 and the lugs 44, 45 within the plate 40 make it possible to obtain a good robustness of this plate, avoiding damage of the ER4 type (this is a dreaded event of severity 4 which is likely to cause bodily injury to the man, such as the loss of the assembly 10 resulting in a loss of control of the vehicle or an impact on the next vehicle).
Un calcul numérique a d'ailleurs été effectué pour vérifier le comportement du dispositif d'assemblage selon l'invention, une fois monté sur la structure de caisse : la tenue en fatigue vibratoire répons à la norme B21 7120 et la tenue en endurance atteint 1 million de cycles de contraintes de 1 g ± 1 ,5g, g étant l'accélération de la pesanteur. A numerical calculation has also been performed to verify the behavior of the assembly device according to the invention, once mounted on the body structure: the vibration fatigue resistance responsive to the B21 7120 standard and endurance resistance reaches 1 million stress cycles of 1 g ± 1, 5g, g being the acceleration of gravity.
L'homme de l'art appréciera donc, par rapport aux dispositifs d'assemblage existants de l'art antérieur, les avantages procurés par un dispositif conforme à l'invention. Those skilled in the art will therefore appreciate, compared to the existing assembly devices of the prior art, the advantages provided by a device according to the invention.
Bien évidemment, l'invention ne se limite pas aux formes de réalisation du dispositif d'assemblage décrit précédemment qui est fourni à titre d'exemple mais elle embrasse au contraire toutes les variantes possibles. Of course, the invention is not limited to the embodiments of the assembly device described above which is provided by way of example but it embraces on the contrary all possible variants.
Par exemple, dans une variante de réalisation, on peut prévoir des renforts mécaniques additionnels sur la platine 40. For example, in an alternative embodiment, additional mechanical reinforcements may be provided on the plate 40.
