Description

La présente invention concerne des volets articulés de véhicules automobiles, tels que portes de coffres, hayons ou capots (voir DE-A-1584059).The present invention relates to articulated shutters of motor vehicles, such as trunk doors, tailgates or hoods (see DE-A-1584059).

Ces volets sont le plus souvent reliés à la caisse du véhicule par au moins deux équilibreurs disposés chacun d'un côté du volet et compensant le poids de celui-ci. La tendance actuelle à les réaliser en matière plastique et d'une façon plus générale à les alléger peut conduire à une diminution de leur rigidité en torsion et en flexion. Les équilibreurs, qui jusqu'à présent sont pneumatiques, peuvent encore accentuer cette torsion et cette flexion du fait de leurs déplacements parfois assez brutaux et dissymétriques lors des mouvements de fermeture des volets.These flaps are most often connected to the vehicle body by at least two balancers each arranged on one side of the flap and compensating for the weight of the latter. The current trend to make them out of plastic and more generally to lighten them can lead to a reduction in their torsional and bending stiffness. Balancers, which until now have been pneumatic, can further accentuate this twist and this bending due to their sometimes quite abrupt and asymmetrical movements during the closing movements of the flaps.

La présente invention a pour objet un volet articulé de véhicule automobile, à équilibreurs, qui est perfectionné de manière à remédier à cet inconvénient.The present invention relates to an articulated shutter of a motor vehicle, with balancers, which is improved so as to remedy this drawback.

Le volet selon l'invention est caractérisé en ce que les équilibreurs sont du type hydropneumatique et sont montés de manière inverse, leurs chambres de liquide étant reliées entre elles par un conduit hydraulique.The shutter according to the invention is characterized in that the balancers are of the hydropneumatic type and are mounted in reverse, their liquid chambers being interconnected by a hydraulic conduit.

Dans un mode de réalisation, les deux équilibreurs montés de manière inverse et ayant leurs chambres de liquide reliées entre elles sont disposés l'un d'un côté du volet et l'autre du côté opposé. On assure ainsi un blocage de la torsion du volet.In one embodiment, the two balancers mounted in reverse and having their liquid chambers connected to each other are arranged one on one side of the flap and the other on the opposite side. This ensures locking of the twist of the flap.

Dans un autre mode de réalisation, le volet est relié à la caisse du véhicule par deux paires d'équilibreurs disposées chacune d'un côté du volet et les équilibreurs de chaque paire sont montés de manière inverse en ayant leurs chambres de liquide reliées par un conduit hydraulique.In another embodiment, the flap is connected to the vehicle body by two pairs of balancers each arranged on one side of the flap and the balancers of each pair are mounted in reverse by having their liquid chambers connected by a hydraulic conduit.

Il peut éventuellement être prévu un conduit muni d'un étrangleur et reliant les chambres des équilibreurs contenant le gaz.A conduit may possibly be provided fitted with a throttle and connecting the chambers of the balancers containing the gas.

On a décrit ci-après, à titre d'exemples non limitatifs, deux modes de réalisation du volet articulé selon l'invention avec référence au dessin annexé dans lequel:

  • la figure 1 montre un premier mode de réalisation permettant un blocage de la torsion;
  • la figure 2 montre un second mode de réalisation permettant un blocage de la flexion.
Two embodiments of the articulated shutter according to the invention have been described below, by way of non-limiting examples, with reference to the appended drawing in which:
  • Figure 1 shows a first embodiment for locking the torsion;
  • Figure 2 shows a second embodiment for blocking the flexion.

A la figure 1, on voit en 1 une porte du coffre ou hayon qui est articulée autour d'un axe 2 par rapport à la caisse 3 du véhicule, d'une manière analogue à celle représentée à la figure 2.In FIG. 1, we see at 1 a trunk door or tailgate which is articulated around an axis 2 relative to the body 3 of the vehicle, in a manner similar to that shown in FIG. 2.

De chaque côté du volet sont prévus des équilibreurs hydrauliques 4a et 4b identiques. Chaque équilibreur comprend un cylindre 5 qui est articulé en 6 sur la caisse 3 et dans lequel est monté coulissant un piston 7 solidaire d'une tige 8; celle-ci est articulée en 9 sur le volet 1. Le piston délimite dans le cylindre 5 une chambre 10 contenant un liquide et une chambre 11 contenant un gaz. Les équilibreurs 4a et 4b sont montés de manière inverse, c'est-à-dire que la chambre 10 de l'équilibreur 4a se trouve du côté du volet 1, alors que la chambre 10 de l'équilibreur 4b se trouve du côté de la caisse 3. Un conduit 12 relie les chambres 10. Il peut également être prévu un conduit 13 muni d'un étrangleur 14 et reliant les chambres 11.On each side of the flap are provided hydraulic balancers 4a and 4b identical. Each balancer comprises a cylinder 5 which is articulated at 6 on the body 3 and in which is slidably mounted a piston 7 secured to a rod 8; this is articulated at 9 on the flap 1. The piston delimits in the cylinder 5 a chamber 10 containing a liquid and a chamber 11 containing a gas. The balancers 4a and 4b are mounted in reverse, that is to say that the chamber 10 of the balancer 4a is on the side of the flap 1, while the chamber 10 of the balancer 4b is on the side of the body 3. A conduit 12 connects the chambers 10. There may also be provided a conduit 13 provided with a throttle 14 and connecting the chambers 11.

Si, en fonctionnement, le volet 1 subit une torsion, par exemple si son côté gauche a tendance à se trouver plus bas que son côté droit, le piston 7 de l'équilibreur 4b chasse un peu de liquide de la chambre 10 de cet équilibreur vers la chambre 10 de l'équilibreur 4a, ce qui rétablit l'équilibre en ramenant à des valeurs identiques les courses des équilibreurs.If, in operation, the flap 1 undergoes a twist, for example if its left side tends to be lower than its right side, the piston 7 of the balancer 4b drives out a little liquid from the chamber 10 of this balancer towards the chamber 10 of the balancer 4a, which restores the balance by bringing the strokes of the balancers to identical values.

Dans le mode de réalisation de la figure 2, chacun des côtés du volet 1 est relié à la caisse 3 par deux équilibreurs 4a-4'a et 4b-4'b, seuls les équilibreurs4a et4'a étant visibles au dessin. Ces équilibreurs ne sont pas identiques: leurs sections sont sensiblement inversement proportionnelles à la distance qui les sépare de l'axe de pivotement 2. Comme dans le mode de réalisation précédent, ils sont disposés en sens inverse et un conduit 12 relie les chambres 10 des équilibreurs situés d'un même côté du volet articulé.In the embodiment of Figure 2, each side of the flap 1 is connected to the body 3 by two balancers 4a-4'a and 4b-4'b, only the balancers 4a and 4'a being visible in the drawing. These balancers are not identical: their sections are substantially inversely proportional to the distance which separates them from the pivot axis 2. As in the previous embodiment, they are arranged in opposite directions and a conduit 12 connects the chambers 10 of the balancers located on the same side of the hinged flap.

Si le volet 1 tend à fléchir, la liaison hydraulique des deux équilibreurs 4a et 4'a ou 4b et 4'b par le conduit 12 assure une course de chaque équilibreur proportionnelle à la distance séparant celui-ci de l'axe d'articulation 2 et s'oppose par suite à cette flexion.If the flap 1 tends to bend, the hydraulic connection of the two balancers 4a and 4'a or 4b and 4'b by the conduit 12 ensures a stroke of each balancer proportional to the distance separating the latter from the axis of articulation 2 and therefore opposes this bending.
