Description

DISPOSITIF DE TRAVERSEE ETANTANCHE D'UNE PAROI COUVERTE PAR UN
INSONORISANT T
L'invention concerne un dispositif de traversée étanche d'une paroi couverte par un insonorisant.WATERPROOF CROSSING DEVICE OF A WALL COVERED BY A
SOUNDPROOFING T
The invention relates to a device for sealingly crossing a wall covered by a soundproofing.

L'invention concerne plus particulièrement un dispositif de traversée étanche appliquée à un mécanisme qui possède un arbre qui s'étend au travers d'un manchon fixé aux bords d'une ouverture de la paroi.The invention relates more particularly to a sealed passage device applied to a mechanism which has a shaft which extends through a sleeve fixed to the edges of an opening in the wall.

La publication DE-A-2919953 décrit un dispositif de traversée constitué par un manchon fixé extérieurement à la paroi dont une portion interne assure l'étanchéité au contact d'un carter de direction.The publication DE-A-2919953 describes a crossing device constituted by a sleeve fixed externally to the wall, an internal portion of which seals in contact with a steering casing.

La publication EP-A-0300854 décrit une traversée de paroi dans laquelle l'arbre de direction est entouré par un soufflet solidaire de la paroi dans le but d'isoler l'habitacle des bruits et odeurs en provenance du compartiment moteur.The publication EP-A-0300854 describes a wall crossing in which the steering shaft is surrounded by a bellows secured to the wall in order to isolate the passenger compartment from noise and odors coming from the engine compartment.

Lorsque la paroi est couverte par un revêtement insonorisant et percée d'un orifice de passage d'arbre, les bords de celui ci doivent contenir un joint d'étanchéité de l'arbre et un moyen de serrage du revêtement.When the wall is covered by a sound-absorbing covering and pierced with a shaft passage orifice, the edges of the latter must contain a shaft seal and a means of tightening the covering.

L'invention a pour objet un dispositif de traversée étanche dans lequel le soufflet d'étanchéité est accolé au moyen d'accrochage d'une rondelle de retenue du revêtement.The subject of the invention is a sealed crossing device in which the sealing bellows is attached by means of attachment of a coating retaining washer.

Selon l'invention un organe de serrage du revêtement possède une surface d'appui périphérique de pincement du revêtement et une zone d'encliquetage sur un élément de retenue du soufflet d'étanchéité. According to the invention, a covering clamping member has a peripheral support surface for pinching the covering and a snap zone on a retaining element of the sealing bellows.

Le dispositif ainsi réalisé remplit la fonction de maintien du revêtement au contact de l'orifice de traversée de la paroi et s'oppose à rarrachement dudit revêtement.The device thus produced fulfills the function of keeping the coating in contact with the orifice through which the wall passes and opposes the removal of said coating.

Le dispositif permet en outre la constitution très simple d'une chambre à air qui isole phoniquement le passage d'un arbre de mécanisme.The device also allows the very simple constitution of an air chamber which phonically isolates the passage of a mechanism shaft.

D'autres caractéristiques et avantages de l'invention apparaitront à la lecture de la description d'un mode de réalisation du dispositif en référence au dessin annexé dans lequel:
- la figure 1 est une représentation schématique vue en
coupe axiale d'une partie de la carrosserie d'un
véhicule portant le dispositif de traversée de paroi.Other characteristics and advantages of the invention will appear on reading the description of an embodiment of the device with reference to the appended drawing in which:
- Figure 1 is a schematic representation seen in
axial section of part of the body of a
vehicle carrying the wall crossing device.

- la figure 2 est une représentation à une plus grande
échelle du dispositif de traversée.- Figure 2 is a representation at a larger
scale of the crossing device.

Le dispositif de traversée de paroi tel que représenté est appliqué à titre d'exemple à un mécanisme de direction dans lequel l'effort de commande est communiqué par un volant 1 à un arbre de direction 2 en deux tronçons 2a, 2b accouplés par un joint de transmission 3. Le tronçon inférieur 2b de l'arbre 2 est rendu solidaire de l'arbre d'entrée 4a d'une valve de direction 4 dont la fonction bien connue consiste dans le cas présent à alimenter la chambre de pression d'un vérin d'assistance de l'effort de commande d'une crémaillère d'actionnement d'un embiellage non représenté sous l'effet de l'effort de commande communiqué par l'arbre 2. The wall crossing device as shown is applied by way of example to a steering mechanism in which the control force is communicated by a steering wheel 1 to a steering shaft 2 in two sections 2a, 2b coupled by a joint transmission 3. The lower section 2b of the shaft 2 is made integral with the input shaft 4a of a direction valve 4 whose well-known function consists in the present case of supplying the pressure chamber with a jack for assisting the control force of a rack for actuating a connecting rod assembly not shown under the effect of the control force communicated by the shaft 2.

L'arbre d'entrée 4a de la valve s'étend au travers d'une paroi de plancher 10 couverte par un revêtement insonorisant 11. A cet effet la paroi 10 possède un orifice de passage 12 dont le bord est encastré dans une gorge de montage prévue sur la collerette de fixation 13 d'un soufflet d'étanchéité 15 à paroi souple 14.The inlet shaft 4a of the valve extends through a floor wall 10 covered by a sound-absorbing coating 11. For this purpose the wall 10 has a passage orifice 12 whose edge is embedded in a groove of mounting provided on the fixing flange 13 of a sealing bellows 15 with flexible wall 14.

L'autre extrémité du soufflet 15 est munie d'une collerette 16 emboitée sur une nervure 17 porté à titre d'exemple par le corps 18 de la valve de direction 4
Un dispositif de maintien du soufflet 15 sur le corps 18 est constitué par un élément de retenue 20 tubulaire qui est traversé axialement par l'arbre 4a et qui possède une base d'accrochage 21 dont la face circulaire constitue une surface d'étanchéité 22 en appui sur la collerette 16.The other end of the bellows 15 is provided with a collar 16 fitted on a rib 17 carried, for example, by the body 18 of the direction valve 4
A device for holding the bellows 15 on the body 18 is constituted by a tubular retaining element 20 which is traversed axially by the shaft 4a and which has a hooking base 21 whose circular face constitutes a sealing surface 22 in support on the collar 16.

La base d'accrochage 21 de l'élément de retenue porte par ailleurs des griffes 23 engagées dans une gorge 24 du corps 18 qui s'opposent à l'arrachement axial de l'élément 20 tout en prenant appui sur la collerette 16 du joint.The attachment base 21 of the retaining element also carries claws 23 engaged in a groove 24 of the body 18 which oppose the axial tearing of the element 20 while bearing on the flange 16 of the seal .

La partie tubulaire de l'élément 20 porte à titre d'exemple un certain nombre d'ergots 25 répartis à la périphérie de celle-ci et ces ergots assurent la retenue axiale d'une rondelle de serrage 26. A cet effet, la rondelle 26 possède une surface périphérique 27 d'appui sur le revêtement 11 susceptible d'assurer son pincement contre la paroi 10 par suite du montage de ladite rondelle 26 sur l'élément 20.The tubular part of the element 20 carries by way of example a number of lugs 25 distributed around the periphery thereof and these lugs ensure the axial retention of a tightening washer 26. For this purpose, the washer 26 has a peripheral surface 27 bearing on the covering 11 capable of pinching it against the wall 10 as a result of the mounting of said washer 26 on the element 20.

L'immobilisation axiale de la rondelle 26 est assurée par suite de l'engagement des ergots 25 dans des gorges intérieures d'encliquetage 28 de la rondelle 26.The axial immobilization of the washer 26 is ensured as a result of the engagement of the lugs 25 in internal snap grooves 28 of the washer 26.

Dans le but d'isoler phoniquement les deux côtés de la paroi 10 au niveau du dispositif de traversée, l'invention prévoit la confection d'une chambre à air 30 délimitée par la paroi 14 du soufflet et par la rondelle 26. A cet effet on réalise avantageusement une étanchéité améliorée au niveau du contact des ergots 25 et des gorges 28.With the aim of soundproofing the two sides of the wall 10 at the crossing device, the invention provides for the construction of an air chamber 30 delimited by the wall 14 of the bellows and by the washer 26. To this end advantageously, an improved seal is produced at the level of the contact of the pins 25 and of the grooves 28.

Le dispositif ainsi réalisé permet l'assemblage préalable du soufflet 15 et de rélément de retenue 20 sur la valve et l'obtention de la fonction d'isolation phonique par simple montage de la rondelle de serrage 26. The device thus produced allows the prior assembly of the bellows 15 and of the retaining element 20 on the valve and the obtaining of the sound insulation function by simple mounting of the tightening washer 26.
