Description

DISPOSITIF D'ARTICULATION D'UN HAYON SUR UN
ELEMENT DE CARROSSERIE
L'invention concerne un dispositif d'articulation d'un hayon de véhicule automobile sur un élément de carrosserie de véhicule automobile constitué par un panneau masquant l'évidement d'un cadre de structure délimité par une traverse supérieure, deux montants latéraux et par une traverse inférieure parmi lesquels chaque montant latéral porte l'axe de montage de l'extrémité d'une bielle de manoeuvre du hayon dont l'autre extrémité est articulée sur l'élément de carrosserie.DEVICE FOR ARTICULATING A TAILGATE ON A
BODY ELEMENT
The invention relates to a device for articulation of a motor vehicle tailgate on a motor vehicle body element constituted by a panel masking the recess of a structural frame delimited by an upper cross member, two lateral uprights and by a lower cross member, among which each lateral upright carries the mounting axis of the end of a tailgate operating rod, the other end of which is articulated on the bodywork element.

Un tel hayon est disposé à l'arrière du véhicule et donne accès à un compartiment à bagages.Such a tailgate is arranged at the rear of the vehicle and gives access to a luggage compartment.

Pour faciliter l'accès au compartiment à bagages et pour pouvoir y introduire le volume de chargement, la manipulation du hayon est usuellement assistée par un ressort équilibreur télescopique.To facilitate access to the luggage compartment and to be able to introduce the load volume into it, handling of the tailgate is usually assisted by a telescopic balancing spring.

Ces ressorts équilibreurs ont pour rôle d'exercer sur le hayon un effort qui s'oppose au poids du hayon et facilitent de ce fait son ouverture et le maintien de celui-ci en position ouverte.These balancing springs have the role of exerting on the tailgate an effort which opposes the weight of the tailgate and thereby facilitate its opening and the maintenance thereof in the open position.

En règle générale ces ressorts sont agencés dans des gouttières latérales de la carrosserie ou le long des montants arrière du pavillon si bien que leur ligne d'action passe au voisinage de l'axe d'articulation du hayon. Un tel agencement est décrit dans la publication US-A-3851867. n en résulte que l'utilisateur doit exercer un effort manuel non négligeable en début d'ouverture du hayon.As a general rule, these springs are arranged in lateral gutters of the bodywork or along the rear uprights of the roof so that their line of action passes in the vicinity of the axis of articulation of the tailgate. Such an arrangement is described in publication US-A-3851867. As a result, the user must exert a considerable manual effort at the start of opening the tailgate.

Lorsque le hayon occupe une position extrême d'ouverture, on sait que le niveau du bord inférieur de celui-ci peut-être placé hors de l'atteinte manuelle et/ou entrer en contact avec le plafond d'une aire de rangement ou de garage.When the tailgate occupies an extreme opening position, it is known that the level of the lower edge thereof can be placed outside of the manual reach and / or come into contact with the ceiling of a storage or storage area. garage.

L'invention a pour but de remédier à ces inconvénients en réalisant un hayon vitré dont la manipulation courante ne nécessite qu'un effort peu important pour passer de la position fermée à une position ouverte et qui peut être manipulé sans effort notable à partir de ladite position fermée jusqu'à 11 ouverture totale.The object of the invention is to remedy these drawbacks by producing a glazed tailgate, the current handling of which requires only a small effort to pass from the closed position to an open position and which can be handled without significant effort from said closed position until 11 full opening.

L'invention a aussi pour objet un hayon de véhicule articulé susceptible d'être manoeuvré avec un effort réduit.The invention also relates to an articulated vehicle tailgate capable of being maneuvered with reduced effort.

L'invention s'applique plus particulièrement aux hayons dans lesquels une vitre masque l'évidement d'un cadre de structure délimité par une traverse supérieure, deux montants latéraux et par une traverse inférieure, parmi lesquels chaque montant latéral porte l'axe de montage de l'extrémité d'une bielle de manoeuvre du hayon dont l'autre extrémité est articulée sur un axe de montage porté par ledit élément de carrosserie.The invention applies more particularly to tailgates in which a window masks the recess of a structural frame delimited by an upper cross member, two lateral uprights and by a lower cross member, among which each lateral upright carries the mounting axis. of the end of a tailgate operating rod, the other end of which is articulated on a mounting pin carried by said body element.

Selon l'invention chaque axe de montage de la bielle de manoeuvre est porté par un palier rigidement relié à la bielle et une denture centrée sur un axe de montage est en prise d'engrènement avec un organe de transmission qui s'étend le long de la bielle jusqu'à une denture homologue centrée sur l'autre axe de montage de la bielle.According to the invention each mounting pin of the operating rod is carried by a bearing rigidly connected to the rod and a toothing centered on a mounting pin is engaged with a transmission member which extends along the connecting rod to a homologous toothing centered on the other mounting axis of the connecting rod.

Le hayon ainsi réalisé possède l'avantage de pouvoir être monté plus simplement sur le véhicule et permet de simplifier notablement l'agencement des moyens d'équilibrage.The tailgate thus produced has the advantage of being able to be mounted more simply on the vehicle and makes it possible to considerably simplify the arrangement of the balancing means.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'un exemple de réalisation du hayon en référence au dessin annexé dans lequel: - la figure 1 est une vue en élévation de la partie arrière d'une carrosserie
de véhicule automobile équipée du hayon conforme à l'invention.Other characteristics and advantages of the invention will appear on reading the description of an exemplary embodiment of the tailgate with reference to the attached drawing in which: - Figure 1 is an elevational view of the rear part of a bodywork
motor vehicle equipped with the tailgate according to the invention.

de la bielle de manoeuvre dans les plans IV - V de la figure 3. - Figures 4 and 5 represent; L of the characteristic sections of the assembly
of the operating rod in planes IV - V of figure 3.

En référence à la figure 1 la partie arrière de la carrosserie définie par son pavillon 10 comporte un hayon vitré 1 1 pivotant le long du bord supérieur 12 sur la carrosserie.Referring to Figure 1 the rear part of the body defined by its flag 10 comprises a glass tailgate 1 1 pivoting along the upper edge 12 on the body.

Les côtés latéraux du hayon 11 bordent les éléments de carrosserie constitués par les montants arrière 13 du pavillon porteurs d'un vitrage de custode 14.The lateral sides of the tailgate 11 border the bodywork elements formed by the rear uprights 13 of the roof carrying quarter window glazing 14.

Le hayon comporte essentiellement un panneau vitré 15 qui masque l'évidement d'un cadre de structure 17 délimité par une traverse supérieure 18, deux montants latéraux 19 et par une traverse inférieure. Chaque montant arrière 13 porte un premier axe de montage 21 d'une bielle 22 de manoeuvre creuse (figure 4). Le montant 13 constitue la gouttière d'écoulement d'eau et le logement de la bielle 22 en position fermée du hayon (figure 1).The tailgate essentially comprises a glazed panel 15 which masks the recess of a structural frame 17 delimited by an upper cross member 18, two lateral uprights 19 and by a lower cross member. Each rear post 13 carries a first mounting pin 21 of a connecting rod 22 of hollow operation (Figure 4). The upright 13 constitutes the water flow gutter and the housing of the connecting rod 22 in the closed position of the tailgate (Figure 1).

La bielle 22 est articulée par une extrémité sur un axe de montage 26 porté par un étrier de fixation 27 solidarisé au montant 19 (figure 5).The connecting rod 22 is articulated by one end on a mounting pin 26 carried by a fixing bracket 27 secured to the upright 19 (Figure 5).

Selon l'invention chaque axe de montage 21, 26 d'une même bielle de manoeuvre telle que 22 est porté par un palier 28 rigidement relié à ladite bielle dans le but de faciliter le prémontage de la bielle sur le hayon et pour simplifier le raccordement de ladite bielle avec le hayon à l'élément de la carrosserie. According to the invention each mounting pin 21, 26 of the same operating rod such as 22 is carried by a bearing 28 rigidly connected to said rod in order to facilitate the pre-assembly of the rod on the tailgate and to simplify the connection from said connecting rod with the tailgate to the bodywork element.

Dans le but de communiquer au hayon la trajectoire désirée, le palier 28 porte une denture 30, 30' rigidement reliée audit palier 28 et centrée sur chaque axe de montage 21 où 26. A titre d'exemple, la denture 30 est en prise d'engrènement avec un arbre de transmission 31 qui s'étend axialement dans la bielle 22 jusqu'à une denture 30' homologue centrée sur l'autre axe de montage 26.In order to communicate the desired trajectory to the tailgate, the bearing 28 carries a toothing 30, 30 'rigidly connected to said bearing 28 and centered on each mounting pin 21 or 26. For example, the toothing 30 is in engagement with meshing with a transmission shaft 31 which extends axially in the connecting rod 22 to a homologous toothing 30 ′ centered on the other mounting axis 26.

A cet effet l'arbre de transmission 31 porte des dentures d'extrémité 32, 32' respectivement en prise avec les dentures 30, 30'.To this end, the transmission shaft 31 carries end teeth 32, 32 'respectively engaged with the teeth 30, 30'.

La denture d'extrémité 32 ou 32' est portée par un pignon conique 33 dont une prolongation axiale est réahsée sous la forme d'une jupe cylindrique 34 guidée dans le palier 28 de montage de la bielle. The end teeth 32 or 32 ′ are carried by a conical pinion 33, an axial extension of which is rehased in the form of a cylindrical skirt 34 guided in the bearing 28 for mounting the connecting rod.

Ainsi que cela est représenté à la figure 3, les extrémités de la bielle 22 sont bridées au moyen de vis 35 aux paliers 28.As shown in FIG. 3, the ends of the connecting rod 22 are clamped by means of screws 35 at the bearings 28.

Dans le but de compenser le poids du hayon, deux ressorts d'équilibrage 40, 40' sont montés en torsion à proximité des axes de montage 21, 26 et des dentures 30, 30'. Les ressorts de torsion tels que 40, 40' sont respectivement ancrés au palier 28 par l'intermédiaire des brides de raccordement de la bielle et au pignon 33.In order to compensate for the weight of the tailgate, two balancing springs 40, 40 'are mounted in torsion near the mounting pins 21, 26 and the teeth 30, 30'. The torsion springs such as 40, 40 ′ are respectively anchored to the bearing 28 by means of the connecting flanges of the connecting rod and to the pinion 33.

L'équilibrage du hayon 11 est ainsi obtenu par les ressorts 40, 40'. Selon l'exemple de réalisation décrit à la figure 3 les ressorts sont guidés par l'arbre 31.Balancing the tailgate 11 is thus obtained by the springs 40, 40 '. According to the embodiment described in FIG. 3, the springs are guided by the shaft 31.

L'équilibrage du hayon 11 est obtenu par l'action conjuguée des ressorts 40, 40' qui exercent un couple opposé au moment de la force due au poids du hayon rapporté aux axes 21, 26.The balancing of the tailgate 11 is obtained by the combined action of the springs 40, 40 'which exert an opposite torque at the time of the force due to the weight of the tailgate relative to the axes 21, 26.

Le hayon fonctionne de la manière suivante:
Pour obtenir l'ouverture du hayon, on manoeuvre ainsi que cela est bien connu une serrure non représentée. Le poids du hayon 1 1 est équilibré par l'action des ressorts 40, 40'.The tailgate works as follows:
To obtain the opening of the tailgate, it operates as is well known a lock not shown. The weight of the tailgate 1 1 is balanced by the action of the springs 40, 40 '.

Simultanément les arbres 31 exercent une transmission du mouvement de levée sur la partie inférieure du hayon au niveau de son axe d'articulation 26 et les ressorts 40, 40' se détendent.Simultaneously the shafts 31 exert a transmission of the lifting movement on the lower part of the tailgate at its hinge pin 26 and the springs 40, 40 'relax.

Le hayon occupe alors la position soulevée représentée à la figure 1.The tailgate then occupies the raised position shown in Figure 1.

Si l'on désire augmenter l'ouverture d'accès au compartiment à bagages on exerce une poussée sensiblement horizontale sur le hayon 11 vers l'avant pour basculer les bielles 22 autour des axes 21, 26.If it is desired to increase the access opening to the luggage compartment, a substantially horizontal thrust is exerted on the tailgate 11 forwards in order to tilt the connecting rods 22 around the axes 21, 26.

Si l'on désire fermer le hayon on exerce une traction sur le hayon vers l'arrière pour amener les bielles à ressorts dans la position représentée à la figure 1.If you wish to close the tailgate, pull the tailgate backwards to bring the spring rods to the position shown in Figure 1.

Le verrouillage de la ortie avant du hayon s'effectuera conventionnellement en comprimant une garniture d'étanchéité non représentée et engagement d'un pêne porté par la carrosserie dans une gâche portée par le hayon.The locking of the front nettle of the tailgate will be carried out conventionally by compressing a seal not shown and engagement of a bolt carried by the body in a keeper carried by the tailgate.

Sans sortir du cadre de l'invention on pourra soit remplacer l'arbre de transmission 31 par une chaîne contenue dans un carter constitutif de la bielle 22 en prise d'engrènement avec une denture fixe solidaire de chaque axe de montage de la bielle, soit insérer entre deux tronçons de l'arbre de transmission 31 un moteur d'actionnement du hayon.
