DISPOSITIF D' ARTICULATION D' UN CAPOT DE VEHICULE AUTOMOBILE
La présente invention se rapporte à un dispositif d' articulation d'un capot de véhicule automobile, constitué par deux charnières comprenant chacune une part un charnon fixé au capot et d' autre part un charnon fixé au châssis du véhicule.ARTICULATION DEVICE FOR A MOTOR VEHICLE HOOD
The present invention relates to a device for articulation of a motor vehicle hood, consisting of two hinges each comprising on the one hand a knuckle fixed to the hood and on the other hand a knuckle fixed to the chassis of the vehicle.
Les capots moteurs équipant les véhicules industriels s" ouvrent fréquemment de l' arrière vers 1' avant au moyen d' une articulation et d1 une fixation au châssis situées à l' avant du capot. Lorsque le capot est fermé, une fixation sur la cabine assure son maintien en utilisation.The engine hoods fitted to industrial vehicles frequently open from rear to front by means of an articulation and a fixing to the chassis located at the front of the hood. When the hood is closed, a fixing on the cabin ensures its continued use.
Lorsqu' un véhicule circule sur un sol accidenté le châssis est soumis à des torsions alternées ce qui génère des déplacements relatifs importants entre la cabine et la fixation avant du capot. Ces déplacements sont d' autant plus importants que les fixations de la cabine sont plus souples.When a vehicle is traveling on uneven ground, the chassis is subjected to alternating twists, which generates significant relative displacements between the cabin and the front hood attachment. These displacements are all the more important as the fixings of the cabin are more flexible.
Par ailleurs des vibrations se produisent à des accélérations et des fréquences variables ce qui entraîne une fatigue rapide des ensembles fixés sur le châssis.In addition, vibrations occur at variable accelerations and frequencies, which causes rapid fatigue of the assemblies fixed to the chassis.
Du fait de l'importance des déplacements et des vibrations, on a cherché à isoler le capot moteur et la cabine du châssis, en utilisant des matériaux amortissants. On utilise des fixations réalisées à l'aide de plots caoutchouc adhésives sur deux plaques et fixés sur le châssis et le capot. Des charnières s' ajoutent à la fixation du capot pour permettre I' ouverture de celui-ci. Les plots caoutchouc permettent d1 absorber une partie des vibrations mais ne favorisent pas de grands déplacements car leur raideur doit être suffisante pour retenir le capot lors de son ouverture. Par ailleurs les charnières sont des organes sensibles aux vibrations et prennent rapidement du jeu.Because of the importance of displacements and vibrations, we tried to isolate the engine cover and the cabin from the chassis, using shock absorbing materials. Fasteners made using adhesive rubber pads on two plates are used and fixed to the chassis and the cover. Hinges are added to the fixing of the hood to allow the opening of the latter. The rubber studs allow part of the vibrations to be absorbed but do not encourage large displacements because their stiffness must be sufficient to retain the cover when it is opened. In addition, the hinges are organs sensitive to vibrations and take up play quickly.
La présente invention a pour but de fournir un dispositif d'articulation et de suspension de capot moteur n' ayant pas les inconvénients - des dispositifs connus. Le capot moteur ne possède aucune liaison mécanique avec le châssis et est donc isolé des vibrations engendrées par celui-ci.The object of the present invention is to provide an articulation and engine hood suspension device which does not have the drawbacks of known devices. The engine cover has no mechanical connection with the chassis and is therefore isolated from the vibrations generated by it.
Lors des torsions du châssis, le bloc élastique permet les déplacements relatifs capot, cabine, châssis, sans introduire de contraintes locales trop élevées.When the chassis is twisted, the elastic block allows the relative movements of the hood, cabin, chassis, without introducing excessively high local constraints.
Le dispositif selon l'invention est caractérisé par le fait que l' un des charnons de chaque charnière est réalisé en matériau élastomère traversé par l' axe d' articulation du capot.The device according to the invention is characterized in that one of the hinges of each hinge is made of elastomeric material crossed by the hinge pin of the cover.
Selon une caractéristique, le charnon en élastomère est traversé par au moins deux axes de fixation servant à le fixer sur le châssis du véhicule.According to one characteristic, the elastomer knuckle is crossed by at least two fixing pins used to fix it to the chassis of the vehicle.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation donné à titre d' exemple et représenté par les dessins annexés.The invention will now be described in more detail with reference to an embodiment given by way of example and represented by the accompanying drawings.
- La figure 1 est une vue de l' avant d'un véhicule dont le capot moteur
est lié au châssis de véhicule par un dispositif d' articulation selon
l'invention.- Figure 1 is a front view of a vehicle with the engine cover
is linked to the vehicle chassis by an articulation device according to
the invention.
- La figure 2 est une vue en perspective d'une charnière du dispositif.- Figure 2 is a perspective view of a hinge of the device.
- La figure 3 est une coupe horizontale de la figure 2.- Figure 3 is a horizontal section of Figure 2.
- Les figures 4 et 5 représentent des variantes du charnon élastique
d' une charnière.- Figures 4 and 5 show variants of the elastic knuckle
of a hinge.
En se référant aux dessins, le dispositif d' articulation assure -la fixation, la suspension et l'articulation du capot moteur 10 associé à une cabine de véhicule 14.Referring to the drawings, the articulation device ensures the fixing, the suspension and the articulation of the engine hood 10 associated with a vehicle cabin 14.
La liaison du capot 10 au châssis 12 est assurée par deux charnières 13.The cover 10 is connected to the chassis 12 by two hinges 13.
Chaque charnière se compose d' un support ou charnon 8 solidaire du capot et articulé par l'intermédiaire d' un axe d' articulation 3 au second charnon 1 réalisé en matériau élastique. Le capot pivote autour de cet axe 3 à l' ouverture et à la fermeture. Each hinge consists of a support or knuckle 8 secured to the cover and articulated by means of a hinge pin 3 to the second knuckle 1 made of elastic material. The cover pivots around this axis 3 when opening and closing.
le charnon élastique 1 est fixé à sa partie supérieure sur un support 5 solidaire du châssis 12 du véhicule par l'intermédiaire d'un axe de fixation 2. I1 est fixé à sa partie inférieure à une ferrure 6 solidaire du châssis 12, par l'intermédiaire d'un axe de fixation 4. La ferrure 6 présente des boutonnières 7 qui permettent de régler sa position et ainsi de régler le capot par rapport à la cabine.the elastic knuckle 1 is fixed at its upper part to a support 5 secured to the chassis 12 of the vehicle by means of a fixing pin 2. I1 is fixed at its lower part to a fitting 6 secured to the chassis 12, by l 'through a fixing axis 4. The fitting 6 has buttonholes 7 which make it possible to adjust its position and thus to adjust the hood relative to the cabin.
Le support ou charnon 8 a la forme d' un U dans lequel vient se loger le charnon élastique 1.The support or knuckle 8 has the shape of a U in which is housed the elastic knuckle 1.
Le charnon élastique 1 présente une bague 9 enrobée dans l' élastomère.The elastic knuckle 1 has a ring 9 coated in the elastomer.
Elle est traversée par l'axe d' articulation 3 et fait office de coussinet pour guider cet axe 3 dont les extrémités sont tenues dans le support 8.It is crossed by the articulation axis 3 and acts as a bearing to guide this axis 3, the ends of which are held in the support 8.
De ce fait les déplacements latéraux du support 8 sont limités.Therefore the lateral movements of the support 8 are limited.
Le charnon élastique 1 présente par ailleurs des bagues enrobées dans l' élastomère et servant au passage des axes de fixation 2 et 4.The elastic knuckle 1 also has rings coated in the elastomer and used for the passage of the fixing pins 2 and 4.
La bague 9 servant de coussinet à l' axe 3 est de préférence réalisée en une matière plastique favorisant la rotation (polyamide....). L' axe 3 constitue une barre de torsion servant d' assistance lors de l' ouverture du capot.The ring 9 serving as a bearing for the axis 3 is preferably made of a plastic material promoting rotation (polyamide, etc.). The axis 3 constitutes a torsion bar serving as assistance during the opening of the hood.
Les formes convenables du charnon élastique l sont variées. Le mode de réalisation de la figure 4 montre un charnon élastique 1 attaché au châssis à l'aide de trois axes de fixation 2, 4 et 14 qui est approprié lorsque les contraintes sont importantes. Le mode de réalisation de la figure 5 montre un charnon élastique 1 pourvu d' alvéoles 11 permettant d' adapter la souplesse ou la raideur. La forme, la masse et la raideur du charnon élastique 1 dépendent de la place disponible, du poids du capot et de l' utilisation du véhicule.The suitable shapes of the elastic knuckle 1 are varied. The embodiment of Figure 4 shows an elastic knuckle 1 attached to the frame using three fixing pins 2, 4 and 14 which is suitable when the stresses are high. The embodiment of FIG. 5 shows an elastic knuckle 1 provided with cells 11 making it possible to adapt the flexibility or the stiffness. The shape, mass and stiffness of the elastic knuckle 1 depend on the space available, the weight of the hood and the use of the vehicle.
Il est bien entendu que l' on peut sans sortir du cadre de l'invention imaginer des variantes et des perfectionnements de détails et de même envisager l' emploi de moyens équivalents. It is understood that it is possible without departing from the scope of the invention to imagine variants and improvements of details and even envisage the use of equivalent means.
