Description

La présente invention se rapporte à un dispositif d'équilibrage de hayon, destiné à équiper un véhicule automobile.The present invention relates to a tailgate balancing device, intended to equip a motor vehicle.

Dans les véhicules pourvus de hayons, l'équilibrage de ces hayons est habituellement réalisé à l'aide de vérins pneumatiques ou équilibreurs placés, le plus généralement, dans les gouttières latérales du véhicule, ces équilibreurs étant destinés à compenser le poids de ce hayon et à faciliter son ouverture et sa fermeture.In vehicles provided with tailgates, the balancing of these tailgates is usually carried out using pneumatic cylinders or balancers placed, most generally, in the side gutters of the vehicle, these balancers being intended to compensate for the weight of this tailgate and to facilitate its opening and closing.

Malheureusement, ces dispositions ne correspondent pas toujours aux impératifs techniques, ni au fonctionnement cinématique souhaité et l'équilibrage du hayon et en conséquence son maniement ne sont pas toujours satisfaisants.Unfortunately, these provisions do not always correspond to technical requirements, nor to the desired kinematic operation and the balancing of the tailgate and consequently its handling are not always satisfactory.

Le brevet d'invention BE-A-643 216 décrit et représente un dispositif manuel pour l'actionnement d'un lanterneau comportant un mécanisme de rappel dont une extrémité est liée au lanterneau et dont l'autre extrémité est articulée sur le bâti par l'intermédiaire d'un levier de renvoi coudé comportant deux bras inégaux et articulé à son coude sur ledit bâti autour d'un axe sensiblement parallèle à l'axe d'articulation du lanterneau, l'extrémité d'un desdits bras étant en contact avec un chemin de roulement plan fixé sur le lanterneau. Le brevet d'invention US-A-2 544 500 décrit et représente un dispositif semblable pour l'actionnement d'un volet. Le brevet d'invention GB-A-1 167 150 décrit et représente un autre dispositif semblable pour l'actionnement d'un capot.Patent BE-A-643,216 describes and represents a manual device for actuating a skylight comprising a return mechanism, one end of which is linked to the skylight and the other end of which is articulated on the frame by the 'via a bent return lever comprising two unequal arms and articulated at its elbow on said frame around an axis substantially parallel to the axis of articulation of the skylight, the end of one of said arms being in contact with a flat raceway fixed on the skylight. The patent US-A-2 544 500 describes and represents a similar device for actuating a shutter. GB-A-1 167 150 describes and represents another similar device for actuating a cover.

Le dispositif qui vient d'être décrit permet, grâce à la présence du levier coudé, d'obtenir une ouverture automatique du lanterneau dès que la serrure qui le maintient fermé est libérée.The device which has just been described makes it possible, thanks to the presence of the bent lever, to obtain an automatic opening of the skylight as soon as the lock which keeps it closed is released.

La présente invention a pour objet une amélioration au dispositif décrit dans les brevets BE-A-643 216, US-A-2 544 500, GB-A-1 167 150, et qui vise notamment, dans son application à un hayon de véhicule automobile, à l'obtention d'une courbe spécifique de l'effort d'équilibrage en fonction de l'angle d'ouverture qui ne soit pas fonction de la seule caractéristique propre à l'équilibreur.The present invention relates to an improvement to the device described in patents BE-A-643,216, US-A-2,544,500, GB-A-1,167,150, and which aims in particular, in its application to a vehicle tailgate automotive, to obtain a specific curve of the balancing force as a function of the opening angle which is not a function of the sole characteristic of the balancer.

Dans ce but, l'invention propose un dispositif d'équilibrage de hayon de véhicule automobile, ledit hayon étant articulé à la structure du véhicule autour d'un axe horizontal, ce dispositif comprenant au moins un équilibreur, dont une extrémité est liée au hayon par une articulation à rotule éloignée dudit axe, et dont l'autre extrémité est articulée à la structure du véhicule par l'intermédiaire d'un levier de renvoi coudé comportant deux bras inégaux et articulé par son coude à la structure du véhicule autour d'un axe sensiblement parallèle à l'axe d'articulation du hayon, l'extrémité du bras, dirigée vers l'axe, formant articulation pour ladite autre extrémité de l'équilibreur, caractérisé en ce que l'extrémité de l'autre bras de ce levier est un contact avec la surface de came concave d'une came fixée au hayon.To this end, the invention provides a tailgate balancing device for a motor vehicle, said tailgate being articulated to the structure of the vehicle about a horizontal axis, this device comprising at least one balancer, one end of which is linked to the tailgate by a ball joint remote from said axis, and the other end of which is articulated to the structure of the vehicle by means of a bent return lever comprising two unequal arms and articulated by its elbow to the structure of the vehicle around an axis substantially parallel to the axis of articulation of the tailgate, the end of the arm, directed towards the axis, forming an articulation for said other end of the balancer, characterized in that the end of the other arm of this lever is in contact with the concave cam surface of a cam attached to the tailgate.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs mieux de la description donnée ci-après, à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels:

  • - la figure 1 est une vue schématique d'une forme de réalisation du dispositif d'équilibrage selon l'invention;
  • - les figures 2 et 3 sont deux vues plus détaillées d'une partie du dispositif de la figure 1;
  • - la figure 4 est une vue similaire à celle de la figure 1, montrant la géométrie du dispositif dans plusieurs positions d'ouverture;
  • - la figure 5 est un diagramme illustrant le gain d'équilibrage obtenu avec le dispositif selon l'invention, comparé à un dispositif habituel à équilibreurs.
The characteristics and advantages of the invention will emerge more clearly from the description given below, by way of nonlimiting example, with reference to the appended drawings in which:
  • - Figure 1 is a schematic view of an embodiment of the balancing device according to the invention;
  • - Figures 2 and 3 are two more detailed views of a part of the device of Figure 1;
  • - Figure 4 is a view similar to that of Figure 1, showing the geometry of the device in several open positions;
  • - Figure 5 is a diagram illustrating the balancing gain obtained with the device according to the invention, compared to a usual device with balancers.

Dans la forme de réalisation choisie et représentée aux figures 1 à 4, le dispositif d'équilibrage selon l'invention, destiné à équiper le hayon 1 d'un véhicule, articulé à la structure de ce véhicule autour d'un axe 2 horizontal, comprend, de manière connue: un équilibreur 3, qui peut être un vérin pneumatique, lié par une de ses extrémités 4 au hayon 1 par une rotule ou articulation analogue 5, à l'opposé de l'axe 2, et un levier de renvoi 6 de forme coudée comportant deux bras 7 et 8 de longueurs inégales, sensiblement perpendiculaires l'un à l'autre. L'autre extrémité 9 de l'équilibreur 3 est liée par une articulation à rotule 10 à l'extrémité du bras 8 dudit levier 6 qui lui est articulé par son coude autour d'un axe 11, sensiblement parallèle à l'axe 2, lié également à la structure du véhicule en 12.In the embodiment chosen and shown in FIGS. 1 to 4, the balancing device according to the invention, intended to equip the tailgate 1 of a vehicle, articulated to the structure of this vehicle around a horizontal axis 2, comprises, in known manner: a balancer 3, which can be a pneumatic cylinder, connected by one of its ends 4 to the tailgate 1 by a ball joint or similar articulation 5, opposite the axis 2, and a return lever 6 of angled shape comprising two arms 7 and 8 of unequal lengths, substantially perpendicular to each other. The other end 9 of the balancer 3 is linked by a ball joint 10 to the end of the arm 8 of said lever 6 which is articulated to it by its elbow around an axis 11, substantially parallel to axis 2, also linked to the structure of the vehicle at 12.

L'extrémité du bras 7 du levier 6 porte un galet de roulement 14 qui est au contact de la surface concave 15 d'une came 16 fixée au hayon 1, la concavité de cette came étant dirigée vers l'intérieur du hayon et le bras 8 du levier 6 étant sensiblement dirigé vers l'axe 2. On a schématisé par la flèche P, le poids du hayon.The end of the arm 7 of the lever 6 carries a roller 14 which is in contact with the concave surface 15 of a cam 16 fixed to the tailgate 1, the concavity of this cam being directed towards the interior of the tailgate and the arm 8 of the lever 6 being substantially directed towards the axis 2. The weight of the tailgate is shown diagrammatically by the arrow P.

L'équilibreur 3, lié au hayon 1 par le point d'articulation 5, développe sur l'extrémité 10 du levier de renvoi coudé 6 une force Fi dirigée suivant la droite qui joint les axes 5 et 10 des articulations supportant l'équilibreur 3.The balancer 3, linked to the tailgate 1 by the articulation point 5, develops on the end 10 of the bent return lever 6 a force F i directed along the straight line which joins the axes 5 and 10 of the articulations supporting the balancer 3.

La force Fi multipliée par le bras de levier di du bras 8 du levier 6 (d1 étant la distance séparant l'axe 12 de la droite passant par les axes 5 et 10) applique au levier coudé 6 un couple C1 = F1 × d1.The force F i multiplied by the lever arm di of the arm 8 of the lever 6 (d 1 being the distance separating the axis 12 from the straight line passing through the axes 5 and 10) applies to the bent lever 6 a torque C 1 = F 1 × d 1 .

Le couple C1 divisé par le bras de levier d' 1 du bras 7 du levier 6 (d'i étant la distance séparant l'axe 12 de la normale N à la surface de la came 15 passant par le point de contact C du galet 14 avec cette dernière) applique à la came 16 et donc au hayon 1 une force

Figure imgb0001
The torque C 1 divided by the lever arm 1 of the arm 7 of the lever 6 (i being the distance separating the axis 12 from the normal N to the surface of the cam 15 passing through the contact point C of the roller 14 with the latter) applies a force to the cam 16 and therefore to the tailgate 1
Figure imgb0001

La force F2 multipliée par le bras de levier d2 (d2 étant la distance séparant l'axe 2 de la normale N à la surface de la came 15, c'est-à-dire du support de la force F2) applique au hayon 1 un couple d'ouverture C2 = F2 x d2.

Figure imgb0002
The force F 2 multiplied by the lever arm d 2 (d 2 being the distance separating the axis 2 from the normal N to the surface of the cam 15, that is to say from the support of the force F 2 ) applies opening torque C 2 = F 2 xd 2 to tailgate 1.
Figure imgb0002

On a également représenté à la figure 4 quatre positions d'ouverture du hayon 1 (ainsi que les positions correspondantes du levier 6 et de la came 16) de 5° en 5° correspondant à des angles d'ouverture du hayon de 5°, 10°, 15° et 20°. Une telle représentation permet de comprendre aisément le principe d'élaboration du profil de la surface de came 15 en fonction de la courbe d'équilibrage finale réelle que l'on désire obtenir. Il suffit en effet pour chaque angle d'ouverture du hayon de déterminer géométriquement la position du point de contact C correspondant de façon à obtenir la valeur correspondante de C2. Cette détermination précise aurait pour effet d'obtenir un profil de la surface de came 15 irrégulier qui ne serait guère compatible avec une manipulation douce et sans chocs du hayon, il est donc nécessaire de relier les points C déterminés théoriquement par une courbe continue et concave, ceci ayant pour conséquence de modifier légèrement la courbe théorique d'équilibrage pour aboutir à la courbe réelle finale d'équilibrage.FIG. 4 also shows four opening positions of the tailgate 1 (as well as the corresponding positions of the lever 6 and of the cam 16) from 5 ° to 5 ° corresponding to opening angles of the tailgate of 5 °, 10 °, 15 ° and 20 °. Such a representation Sentation makes it easy to understand the principle of developing the profile of the cam surface 15 as a function of the actual final balancing curve that it is desired to obtain. It suffices for each opening angle of the tailgate to geometrically determine the position of the corresponding contact point C so as to obtain the corresponding value of C 2 . This precise determination would have the effect of obtaining an irregular profile of the cam surface 15 which would hardly be compatible with a gentle and shock-free handling of the tailgate, it is therefore necessary to connect the points C determined theoretically by a continuous and concave curve , this having the consequence of slightly modifying the theoretical balancing curve to arrive at the final real balancing curve.

On a représenté à la figure 5 un diagramme, sur lequel on a porté en abscisses, l'angle d'ouverture du hayon et en ordonnées:

  • - le couple résistant offert par le hayon du fait de sa masse P (courbe I);
  • - le couple moteur dû à l'équilibreur 3, sans levier de renvoi coudé (courbe 11);
  • - le couple réel d'équilibrage C2 obtenu grâce au dispositif réalisé conformément aux enseignements de la présente invention (courbe III).
FIG. 5 shows a diagram, on which the opening angle of the tailgate is plotted on the abscissa and on the ordinate:
  • - the resistant torque offered by the tailgate due to its mass P (curve I);
  • - the engine torque due to the balancer 3, without an angled return lever (curve 11);
  • - the actual balancing torque C 2 obtained thanks to the device produced in accordance with the teachings of the present invention (curve III).

L'assistance à l'ouverture s'exerce pendant la course du hayon entre = 0 (fermeture du hayon) et 1 qui est de l'ordre de 20°.The opening assistance is exercised during the tailgate stroke between = 0 (tailgate closing) and 1 which is around 20 °.

Le dispositif selon l'invention, simple et fiable, assure une meilleure distribution de l'énergie contenue dans le ou les équilibreurs, et garantit une ouverture automatique du hayon dès que la serrure de celui-ci est libérée.The device according to the invention, simple and reliable, ensures a better distribution of the energy contained in the balancer (s), and guarantees an automatic opening of the tailgate as soon as the lock of the latter is released.

Bien qu'on ait seulement décrit un dispositif consistant en un équilibreur associé à un levier de renvoi et une came, il va de soi qu'un tel ensemble est avantageusement disposé de chaque côté du hayon à équilibrer.Although we have only described a device consisting of a balancer associated with a deflection lever and a cam, it goes without saying that such an assembly is advantageously disposed on each side of the tailgate to be balanced.
