On connaît du document FR-B1-2 988 025 un dispositif de protection comportant un guide tubulaire permettant l'introduction d'un outil de vissage, de façon à protéger l'environnement de l'outil de vissage lorsqu'on effectue une opération de vissage.We know from the document FR-B1-2 988 025 a protection device comprising a tubular guide allowing the introduction of a screwing tool, so as to protect the environment of the screwing tool when performing a screwing operation.

On connaît aussi un dispositif de protection selon le document US 5,791,213 pour supporter un outil de vissage.A protection device is also known according to the document US 5,791,213 to support a screwdriver.

Un tel dispositif présente notamment comme inconvénient d'être coûteux et encombrant pour l'opérateur effectuant les opérations de vissage.Such a device has the particular drawback of being costly and bulky for the operator performing the screwing operations.

L'invention a pour but de remédier aux inconvénients de l'art antérieur.The object of the invention is to remedy the drawbacks of the prior art.

Dans ce but, la présente invention propose un ensemble comprenant un calculateur d'un groupe motopropulseur de véhicule automobile, un boîtier du calculateur et un capot coopérant avec le boîtier pour fermer hermétiquement le boîtier, remarquable en ce qu'il comprend un dispositif de protection comportant un premier moyen de protection adapté à recevoir un outil de vissage, le premier moyen de protection et le capot étant d'un seul tenant.To this end, the present invention provides an assembly comprising a computer for a motor vehicle powertrain, a computer housing and a cover cooperating with the housing to hermetically close the housing, remarkable in that it comprises a protection device. comprising a first protection means adapted to receive a screwing tool, the first protection means and the cover being in one piece.

Ainsi, l'invention permet d'éviter les contacts entre l'outil de vissage des pièces fragiles du groupe motopropulseur, sans augmenter l'encombrement de l'outil de vissage et avec un coût réduit.Thus, the invention makes it possible to avoid contacts between the screwing tool of fragile parts of the power train, without increasing the size of the screwing tool and at a reduced cost.

L'invention concerne aussi un groupe motopropulseur d'un véhicule comportant au moins un tel ensemble.The invention also relates to a power train of a vehicle comprising at least one such assembly.

L'invention a également pour objet un véhicule automobile comportant un tel groupe motopropulseur.The subject of the invention is also a motor vehicle comprising such a powertrain.

L'invention sera mieux comprise et d'autres aspects et avantages apparaîtront plus clairement à la lecture de la description qui suit de modes particuliers de réalisation, donnés à titre d'exemple nullement limitatifs et en référence aux dessins qui les accompagnent, dans lesquels :

  • la figure 1 est une vue d'un groupe motopropulseur intégrant un dispositif de protection selon un premier mode particulier de réalisation de l'invention, lors d'une opération de vissage ;
  • les figures 2 à 4 sont des zooms sur le dispositif de protection et l'outil de vissage de la figure 1 ;
  • la figure 5 est une vue d'un groupe motopropulseur intégrant un dispositif de protection selon un deuxième mode particulier de réalisation de l'invention, lors d'une opération de vissage ; et
  • la figure 6 est un zoom sur le dispositif de protection de la figure 5.
The invention will be better understood and other aspects and advantages will emerge more clearly on reading the following description of particular embodiments, given by way of non-limiting example and with reference to the drawings which accompany them, in which:
  • the figure 1 is a view of a powertrain incorporating a protection device according to a first particular embodiment of the invention, during a screwing operation;
  • the figures 2 to 4 are zooms on the protection device and the screwing tool of the figure 1 ;
  • the figure 5 is a view of a powertrain incorporating a protection device according to a second particular embodiment of the invention, during a screwing operation; and
  • the figure 6 is a zoom on the protection device of the figure 5 .

Les figures 1 à 4 présentent un groupe motopropulseur d'un véhicule automobile comprenant un moteur thermique 10, une boîte de vitesses 20, un dispositif de protection 30 et un boîtier 40 de calculateur selon un premier mode particulier de réalisation de l'invention.The figures 1 to 4 present a powertrain of a motor vehicle comprising a heat engine 10, a gearbox 20, a protection device 30 and a computer housing 40 according to a first particular embodiment of the invention.

Lors de l'assemblage du groupe motopropulseur, le carter cylindre du moteur thermique 10 et la boîte de vitesses 20 sont assemblés l'un à l'autre par au moins une fixation 21. La fixation 20 est par exemple une vis ou un boulon qui doit être vissé ou dévissé par un outil de vissage 50.During assembly of the power train, the cylinder block of the heat engine 10 and the gearbox 20 are assembled to each other by at least one fixing 21. The fixing 20 is for example a screw or a bolt which must be screwed or unscrewed using a screwing tool 50.

L'outil de vissage 50, appelé aussi visseuse, comprend une poignée 51 pour la préhension de l'outil 50 par un opérateur et une rallonge 52 destinée à coopérer avec la fixation 21 lors des opérations de vissage.The screwing tool 50, also called a screwdriver, comprises a handle 51 for gripping the tool 50 by an operator and an extension 52 intended to cooperate with the binding 21 during screwing operations.

La boîte de vitesses 20 est par exemple une boîte de vitesses automatique, mais d'autres types de boîtes de vitesses peuvent être envisagés, dès lors que cette boîte de vitesse est implantée dans un environnement rendant difficile l'accès à la fixation 21.The gearbox 20 is for example an automatic gearbox, but other types of gearboxes can be envisaged, since this gearbox is located in an environment making access to the fixing 21 difficult.

La boîte de vitesses 20 peut également comporter un tube 22, dit reniflard, pour la mise à l'air libre du carter de la boîte de vitesses. Un tel tube 22 est généralement réalisé dans un matériau souple et présente donc un risque d'endommagement en cas de contact avec l'outil de vissage 50.The gearbox 20 can also include a tube 22, called a breather, for venting the gearbox housing. Such a tube 22 is generally made of a flexible material and therefore presents a risk of damage in the event of contact with the screwing tool 50.

Le tube 22 peut également compliquer l'accès à la fixation 21 par l'outil 50. Ainsi, dans la configuration présentée sur la figure 1, une extrémité du tube 22 se trouve à proximité de la fixation 21 et présente donc un risque de contact avec l'outil de vissage 40.The tube 22 can also complicate access to the fastener 21 by the tool 50. Thus, in the configuration shown in figure 1 , one end of the tube 22 is located near the fixing 21 and therefore presents a risk of contact with the screwing tool 40.

Par exemple, le boîtier 40 est fixé sur la boîte de vitesses 20 et contient un calculateur étant destiné au pilotage de la boîte de vitesses 20. Le boîtier 40 comporte en outre un connecteur 45 pour connecter le calculateur à d'autres éléments au moyen d'un câble (non illustré).For example, the box 40 is fixed to the gearbox 20 and contains a computer being intended for controlling the gearbox 20. The box 40 also includes a connector 45 for connecting the computer to other elements by means of 'a cable (not shown).

Le dispositif de protection 30 comporte un capot 31 adapté à coopérer avec le boîtier 40 de façon à fermer hermétiquement le boîtier 40.The protection device 30 comprises a cover 31 adapted to cooperate with the housing 40 so as to hermetically close the housing 40.

Le dispositif de protection 30 est généralement en matière plastique.The protection device 30 is generally made of plastic.

Lors des opérations de vissage, l'embout 42 de l'outil de vissage risque d'entrer en contact avec le connecteur 45 ou avec le tube 22.During screwing operations, the tip 42 of the screwing tool risks coming into contact with the connector 45 or with the tube 22.

Le dispositif de protection 30 comporte en outre un premier élément de protection 32, adapté à recevoir l'outil de vissage 50. Ainsi on évite que l'outil de vissage 40 n'endommage le connecteur 45 et/ou le tube 22 lors de l'assemblage du groupe motopropulseur.The protection device 30 further comprises a first protection element 32, adapted to receive the screwing tool 50. This prevents the screwing tool 40 from damaging the connector 45 and / or the tube 22 during the powertrain assembly.

Conformément à l'invention, le premier élément de protection 32 et le capot 31 sont d'un seul tenant.According to the invention, the first protection element 32 and the cover 31 are made in one piece.

Le capot 31 et le premier élément de protection 32 sont par exemple obtenus par un processus d'injection plastique.The cover 31 and the first protection element 32 are for example obtained by a plastic injection process.

Le premier élément de protection 32 forme un relief par rapport à une surface du capot 31 et a par exemple la forme d'une gouttière, ou encoche.The first protective element 32 forms a relief relative to a surface of the cover 31 and has for example the shape of a gutter, or notch.

La longueur de portée du premier l'élément de protection 32 est définie de façon à assurer le meilleur compromis entre le guidage de l'outil 50 et l'encombrement de cet élément de protection 32. Par exemple, cette longueur de portée peut-être comprise entre 5 et 80 mm.The bearing length of the first protective element 32 is defined so as to ensure the best compromise between the guiding of the tool 50 and the size of this protection element 32. For example, this span length may be between 5 and 80 mm.

Les figures 5 et 6 présentent un groupe motopropulseur d'un véhicule automobile comprenant le moteur thermique 10, la boîte de vitesses 20, le boîtier 40 de calculateur et un dispositif de protection 130 selon un second mode particulier de réalisation de l'invention.The figures 5 and 6 present a powertrain of a motor vehicle comprising the heat engine 10, the gearbox 20, the computer housing 40 and a protection device 130 according to a second particular embodiment of the invention.

Le carter cylindre du moteur thermique 10 et la boîte de vitesses 20 sont également assemblés l'un à l'autre par au moins une fixation 21, identique à celle des figures 1 à 4, qui doit être vissée ou dévissée par l'outil de vissage 50.The cylinder block of the heat engine 10 and the gearbox 20 are also assembled to each other by at least one fixing 21, identical to that of the figures 1 to 4 , which must be screwed in or out with the screwdriver 50.

Le dispositif de protection 130 comporte un capot 131, généralement en matière plastique.The protection device 130 comprises a cover 131, generally made of plastic.

Le dispositif de protection 130 comporte en outre un premier élément de protection 132, adapté à recevoir l'outil de vissage 50 et un second élément de protection 133 conçu pour protéger l'extrémité du tube 22. Ainsi on évite que l'outil de vissage 50 n'endommage le connecteur 45 et/ou le tube 22 lors de l'assemblage du groupe motopropulseur.The protection device 130 further comprises a first protection element 132, adapted to receive the screwing tool 50 and a second protection element 133 designed to protect the end of the tube 22. Thus it is avoided that the screwing tool 50 does not damage connector 45 and / or tube 22 when assembling the powertrain.

Le premier élément de protection 132 est représenté ici avec une longueur de portée plus importante que celle de l'élément de protection 32 présenté aux figures 1 à 4. Le premier élément de protection 132 peut cependant avoir une longueur inférieure, cette longueur étant définie de façon à assurer le meilleur compromis entre le guidage de l'outil 50 et l'encombrement de cet élément de protection 132. Par exemple, cette longueur de portée peut-être comprise entre 5 et 80 mm.The first protection element 132 is shown here with a longer span length than that of the protection element 32 presented in figures 1 to 4 . The first protection element 132 may however have a shorter length, this length being defined so as to ensure the best compromise between the guiding of the tool 50 and the bulk of this protection element 132. For example, this span length maybe between 5 and 80 mm.

Le premier élément de protection 132, le second élément de protection 133 et le capot 131 sont d'un seul tenant.The first protection element 132, the second protection element 133 and the cover 131 are in one piece.

Le capot 131, le premier élément de protection 132 et le second élément de protection 133 sont par exemple obtenus par un processus d'injection plastique.The cover 131, the first protection element 132 and the second protection element 133 are for example obtained by a plastic injection process.

Le premier élément de protection 132 constitue un relief par rapport au capot 131 et a par exemple la forme d'une gouttière, ou encoche, et le second élément de protection 133 a la forme d'une cloche apte à recevoir l'extrémité du tube 22.The first protection element 132 constitutes a relief relative to the cover 131 and has for example the shape of a gutter, or notch, and the second protection element 133 has the shape of a bell capable of receiving the end of the tube. 22.

Le second élément de protection 133 permet de créer une butée physique entre l'outil de vissage 50 et l'extrémité du tube 22, ce qui protège le tube d'agressions éventuelles de l'outil 50 lors d'opérations de montage ou de démontage du groupe motopropulseur. Ainsi, le second élément de protection 133 permet que le dispositif de protection 130 assure une meilleure protection du tube 22 que dans le premier mode de radialisation de l'invention décrit aux figures 1 à 4.The second protection element 133 makes it possible to create a physical stop between the screwing tool 50 and the end of the tube 22, which protects the tube from possible attacks on the tool 50 during assembly or disassembly operations. of the powertrain. Thus, the second element of protection 133 allows the protection device 130 to provide better protection of the tube 22 than in the first method of radialization of the invention described in figures 1 to 4 .

La forme en cloche du second élément de protection 133 présente en outre comme avantage de protéger l'extrémité du tube 22 des projections d'eau. De telles projections d'eau peuvent par exemple être occasionnées par le passage d'un gué par le véhicule.The bell shape of the second protective element 133 also has the advantage of protecting the end of the tube 22 from splashing water. Such water splashes can for example be caused by the passage of a ford by the vehicle.

Ainsi, un tel dispositif permet d'éviter les contacts entre un outil de vissage et une pièce fragile du groupe motopropulseur, sans augmenter l'encombrement de l'outil de vissage et avec un coût réduit.Thus, such a device makes it possible to avoid contact between a screwing tool and a fragile part of the power train, without increasing the size of the screwing tool and at a reduced cost.
