Description
L’invention concerne un système d’insonorisation pour moteur de véhicule automobile, un ensemble pour un tel système et un procédé de montage d’un tel système.The invention relates to a soundproofing system for a motor vehicle engine, an assembly for such a system and a method of mounting such a system.
Il est connu de réaliser un système d’insonorisation pour moteur de véhicule automobile, ledit système comprenant : • un capot d’insonorisation à base de fibres liées entre elles par un liant, ledit capot présentant une forme générale de cuvette, de manière à être pourvu de deux parois opposées se faisant face, • des moyens de fixation montée en bordure desdites parois, • une embase, solidaire dudit moteur, de réception desdits moyens.It is known to produce a soundproofing system for a motor vehicle engine, said system comprising: a soundproofing hood based on fibers bonded together by a binder, said cap having a general shape of a bowl, so as to be provided with two opposing walls facing each other, • fastening means mounted on the edge of said walls, • a base, integral with said motor, for receiving said means.
Un moyen de fixation connu comprend notamment des vis « quart de tour » ou des agrafes « sapin » venant s’emboîter dans des moyens de réception spécifiques prévus sur l’embase.A known fastening means comprises in particular "quarter-turn" screws or "fir" staples which fit into specific receiving means provided on the base.
Une telle façon de faire peut présenter divers inconvénients : • les moyens de réception peuvent être d’accès difficile, ce qui complexifie le montage ou démontage du capot, • il peut être nécessaire d’utiliser un outil pour actionner les vis en rotation, • la définition géométrique de l’embase ne permet pas toujours d’y loger de tels moyens de réception. L’invention a pour but de pallier ces inconvénients. A cet effet, et selon un premier aspect, l’invention propose un système d’insonorisation pour moteur de véhicule automobile, ledit système comprenant : • un capot d’insonorisation à base de fibres liées entre elles par un liant, ledit capot présentant une forme générale de cuvette, de manière à être pourvu de deux parois opposées se faisant face, • des moyens de fixation montée en bordure desdites parois, • une embase, solidaire dudit moteur, de réception desdits moyens, chacun desdits moyens de fixation comprenant : • une partie d’ancrage sur la paroi correspondante, ladite partie présentant une première et une deuxième patte entre lesquelles s’insère ladite paroi en contact serrant, ladite première patte étant pourvue d’un ergot saillant vers ladite deuxième patte, ledit ergot s’insérant dans un orifice d’ancrage prévu dans ladite paroi, lesdites pattes pouvant être actionnées de manière à s’écarter élastiquement l’une de l’autre pour permettre le montage dudit moyen sur ladite paroi, • une partie d’emboitement sur ladite embase, ladite partie étant recourbée en son extrémité libre, de manière à s’emboiter sur une butée respective prévue sur ladite embase, sachant que les parties d’emboitement de deux moyens de fixation opposés, disposés sur des parois opposées, sont recourbées l’une vers l’autre ou bien l’une à l’opposé de l’autre, de manière à permettre leur maintien en emboîtement sur les butées correspondantes.Such a method may have various disadvantages: • the receiving means can be difficult to access, which makes it difficult to assemble or disassemble the cover, • it may be necessary to use a tool to actuate the screws in rotation, • the geometric definition of the base does not always allow to accommodate such receiving means. The invention aims to overcome these disadvantages. For this purpose, and according to a first aspect, the invention proposes a soundproofing system for a motor vehicle engine, said system comprising: a soundproofing hood based on fibers bonded together by a binder, said bonnet having a general shape of bowl, so as to be provided with two opposite walls facing each other, • fastening means mounted at the edge of said walls, • a base, integral with said motor, for receiving said means, each of said fixing means comprising: an anchoring part on the corresponding wall, said part having a first and a second tab between which said wall in tight contact is inserted, said first tab being provided with a lug protruding towards said second tab, said pin inserting in an anchoring hole provided in said wall, said tabs being operable to move elastically away from one of the further to allow the mounting of said means on said wall, • a nesting part on said base, said part being bent at its free end, so as to fit on a respective abutment provided on said base, knowing that the parts d interlocking two opposing fixing means, arranged on opposite walls, are bent towards one another or one opposite the other, so as to allow them to be interlocked on the corresponding stops .
Avec l’agencement proposé, le montage ou démontage du capot sur l’embase est simplifié puisque l’on procède à un simple emboîtement, qui ne requiert pas d’outil.With the proposed arrangement, the assembly or disassembly of the cover on the base is simplified since it is a simple interlocking, which requires no tool.
En outre, l’embase doit simplement présenter des butées, ce qui est aisément réalisable pour toutes formes d’embases.In addition, the base must simply have stops, which is easily achievable for all forms of bases.
Par ailleurs, les moyens de fixation se montent très aisément sur le capot, par simple emboîtement, et l’association entre les deux est rendue très robuste de par l’emboitement des ergots dans les orifices d’ancrage.Moreover, the fastening means are mounted very easily on the hood, by simple interlocking, and the association between the two is made very robust by the interlocking lugs in the anchoring holes.
Selon d’autres aspects, l’invention propose un ensemble pour un tel système et un procédé de montage d’un tel système. D’autres particularités et avantages de l’invention apparaîtront dans la description qui suit, faite en référence aux figures jointes, dans lesquelles : • la figure 1 est une vue schématique en perspective d’un ensemble comprenant un capot et des moyens de fixation, pour un système d’insonorisation pour moteur de véhicule automobile selon une réalisation, • les figures 2a et 2b sont des vues en coupe de l’ensemble de la figure 1 monté sur une embase de manière à former un système d’insonorisation, en vue générale (figure 2a) et de détail ( figure 2b), • la figure 3 est une vue en perspective sous deux angles de vue d’un moyen de fixation utilisé dans la réalisation des figures précédentes.In other aspects, the invention provides an assembly for such a system and a method of mounting such a system. Other features and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which: FIG. 1 is a schematic perspective view of an assembly comprising a cover and fixing means, for a soundproofing system for motor vehicle engine according to one embodiment, • Figures 2a and 2b are sectional views of the assembly of Figure 1 mounted on a base so as to form a soundproofing system, for general (figure 2a) and detail (figure 2b), • figure 3 is a perspective view from two angles of view of a fastening means used in the embodiment of the preceding figures.
