Description

Domaine de l'inventionField of the invention

La présente invention concerne le domaine des fermetures motorisées d'une caisse d'un véhicule, et plus particulièrement celui des portes louvoyantes coulissantes pour des rames ferroviaires.The present invention relates to the field of motorized closures of a body of a vehicle, and more particularly that of sliding doors sliding rail trains.

Etat de la techniqueState of the art

Il est connu d'équiper les rames ferroviaires de trains à grande vitesse de portes louvoyantes coulissantes dont le mouvement présente une phase d'ouverture où le bord arrière commence à s'écarter du logement par un déplacement transversal, vers l'extérieur de la caisse. Ensuite, la partie avant s'écartant à son tour par un déplacement comportant une composante longitudinale et une composante transversale lorsqu'elle est libérée et simultanément la porte se déplace longitudinalement pour libérer l'ouverture pratiquée dans la caisse. Ce mouvement permet d'assurer une parfaite étanchéité lorsque la porte est fermée, et de réduire l'ouverture pratiquée dans la caisse, au droit de la partie arrière, lors de l'ouverture ou la fermeture de la porte.It is known to equip train trains of high speed sliding sliding doors whose movement has an opening phase where the rear edge begins to move away from the housing by a transverse movement towards the outside of the body . Then, the front part deviating in turn by a displacement having a longitudinal component and a transverse component when released and simultaneously the door moves longitudinally to release the opening made in the box. This movement ensures a perfect seal when the door is closed, and reduce the opening made in the box, to the right of the rear part, when opening or closing the door.

A titre d'exemple, le brevet EP1167672 décrit un mécanisme d'actionnement de telles portes louvoyantes-coulissantes. Il est constitué d'un chariot destiné à être fixé sur un des bords de la porte et dont la trajectoire est identique à celle de la porte. Ce chariot coulisse à l'aide de poulies sur un profil de support qui comporte, dûment solidarisés avec ses extrémités, les extrémités d'une courroie dentée qui passe à travers un jeu de rouleaux montés sur un support solidarisé avec le profil de support. L'un des rouleaux reçoit le mouvement d'un moteur électrique monté sur le support, de manière que la rotation du rotor du moteur dans un sens entraîne le déplacement du chariot dans un sens et, par voie de conséquence, de la porte qui lui est associée, et vice versa. Un bras mobile, également monté sur le support, entraîne le blocage de la porte lors d'une situation limite de fermeture, en s'engageant dans un logement du chariot, position d'engagement à partir de laquelle ledit chariot peut être automatiquement libéré, par la rotation du stator du moteur.For example, the patent EP1167672 discloses a mechanism for actuating such tilting-sliding doors. It consists of a carriage intended to be fixed on one of the edges of the door and whose path is identical to that of the door. This carriage slides with the aid of pulleys on a support profile which includes, duly secured to its ends, the ends of a toothed belt which passes through a set of rollers mounted on a support secured to the profile of support. One of the rollers receives the movement of an electric motor mounted on the support, so that the rotation of the motor rotor in one direction causes the carriage to move in one direction and, consequently, the door which is associated, and vice versa. A movable arm, also mounted on the support, causes the locking of the door during a closing limit situation, by engaging in a housing of the carriage, the engagement position from which said carriage can be automatically released, by the rotation of the motor stator.

On connaît également, des documents FR-2133309 et FR-2053406 , des mécanismes de porte louvoyante-coulissante encombrants.Also known, documents FR-2133309 and FR-2053406 cumbersome sliding door mechanisms.

Il est également connu du document US-4924625 , une porte louvoyante-coulissante conforme au préambule de la revendication 1.It is also known from the document US 4924625 , a sliding-sliding door according to the preamble of claim 1.

But de l'inventionPurpose of the invention

Le but de la présente invention est d'améliorer le mécanisme d'entraînement de portes louvoyantes coulissantes en réduisant l'encombrement de la partie inférieure de la porte et en supprimant les pièces, notamment les crémaillères implantées sur la face intérieure du vantail, qui restaient souvent apparentes dans les solutions de l'art antérieur.The object of the present invention is to improve the drive mechanism sliding sliding doors by reducing the size of the lower part of the door and removing the parts, including the racks located on the inside of the leaf, which remained often apparent in the solutions of the prior art.

Ce mécanisme est en particulier destiné à des trains à grande vitesse, où les phénomènes de surpression lors du passage dans un tunnel ou d'un croisement d'un autre train exercent des efforts importants sur les portes. Dans ce cas, il est nécessaire par ailleurs que la porte comporte des moyens d'étanchéité performants, et que les mécanismes d'ouverture et de fermeture soient compatibles avec ces moyens d'étanchéité.This mechanism is particularly intended for high-speed trains, where the phenomena of overpressure during passage through a tunnel or crossing another train exert significant efforts on the doors. In this case, it is also necessary that the door comprises effective sealing means, and that the opening and closing mechanisms are compatible with these sealing means.

L'invention concerne plus particulièrement un mécanisme destiné aux portes louvoyantes-coulissantes, type de porte pour lesquelles le vantail en position fermé vient s'encastrer dans le plan de l'ouverture de la caisse et qui coulisse à l'extérieur de ce plan pendant le mouvement d'ouverture.The invention relates more particularly to a mechanism for sliding-sliding doors, type of door for which the leaf in the closed position is embedded in the plane of the opening of the body and which slides outside this plane during the opening movement.

Présentation synthétique de l'inventionSynthetic presentation of the invention

L'invention concerne une porte louvoyante coulissante motorisée comportant un vantail suspendu à un mécanisme de suspension et d'entraînement et guidé par un rail de guidage solidaire de la caisse, le mécanisme d'entraînement comportant un tube de suspension articulé agencé pour supporter le poids du vantail. L'une des extrémités dudit tube est articulé par rapport à un premier chariot mobile transversalement, notamment le chariot arrière, par une articulation présentant au moins un degré de liberté en rotation dans un plan horizontal et un degré de liberté en translation axiale.The invention relates to a motorized sliding sliding door comprising a leaf suspended from a suspension and driving mechanism and guided by a guide rail integral with the body, the driving mechanism comprising an articulated suspension tube arranged to support the weight leaf. One end of said tube is articulated relative to a first transversely movable carriage, in particular the rear carriage, by a hinge having at least one degree of freedom in rotation in a horizontal plane and a degree of freedom in axial translation.

L'autre extrémité dudit tube est articulé par rapport à un deuxième chariot mobile transversalement, généralement le chariot avant, par une articulation présentant au moins un degré de liberté en rotation dans un plan horizontal. Le vantail comprend un bras présentant une douille de coulissement coopérant avec le tube de suspension.The other end of said tube is hinged relative to a second transversely movable carriage, generally the front carriage, by a hinge having at least one degree of freedom in rotation in a horizontal plane. The leaf comprises an arm having a sliding sleeve cooperating with the suspension tube.

Selon une variante avantageuse, les deux chariots sont mobiles selon une direction transversale, avec un écartement fixe. Cela permet une cinématique de sortie de porte où la porte reste parallèle à la caisse.According to an advantageous variant, the two carriages are movable in a transverse direction, with a fixed spacing. This allows a door release kinematics where the door remains parallel to the body.

Selon une variante, les deux chariots étant mobiles selon des directions transversales parallèles, à écartement fixe.According to a variant, the two carriages being movable in parallel transverse directions, with fixed spacing.

Avantageusement, le mécanisme d'entraînement comporte une barre de conjugaison disposée longitudinalement et maintenue par deux paliers fixes par rapport à la caisse, l'une des extrémité entraînant le déplacement transversal du premier chariot et l'autre extrémité assurant le blocage du second chariot pendant le déplacement transversal du premier chariot, en combinaison avec le blocage en translation longitudinale du vantail.Advantageously, the drive mechanism comprises a conjugation bar arranged longitudinally and held by two fixed bearings by relative to the body, one end causing the transverse displacement of the first carriage and the other end ensuring the locking of the second carriage during the transverse displacement of the first carriage, in combination with the locking in longitudinal translation of the leaf.

De préférence, le déplacement transversal du premier chariot est assuré par un système bielle-manivelle.Preferably, the transverse displacement of the first carriage is provided by a crank-crank system.

Selon un mode de réalisation préféré, la droite passant par l'axe d'articulation de la bielle sur le chariot et par l'axe du maneton de la barre de conjugaison est décalée de l'axe de la barre de conjugaison, en position fermée. Cette disposition à arc-boutement réalise le verrouillage de la porte, en position fermée, et conduit à une amplification du blocage en cas de contrainte vers l'ouverture.According to a preferred embodiment, the straight line passing through the axis of articulation of the connecting rod on the carriage and the axis of the crank pin of the conjugation bar is offset from the axis of the conjugation bar, in the closed position. . This arching arrangement makes the locking of the door, in the closed position, and leads to amplification of the blocking in the event of stress towards the opening.

Avantageusement, la barre de conjugaison présente un maneton muni d'un galet, coopérant avec un chemin de guidage solidaire du second chariot, ce chemin de guidage présentant un segment courbe empêchant le déplacement transversal du second chariot pendant la phase de déboîtement du premier chariot. Ce segment courbe est prolongé par un segment transversal autorisant le déplacement transversal du second chariot.Advantageously, the conjugation bar has a crankpin provided with a roller cooperating with a guide path secured to the second carriage, this guide path having a curved segment preventing transverse displacement of the second carriage during the disengagement phase of the first carriage. This curved segment is extended by a transverse segment allowing the transverse displacement of the second carriage.

Le mouvement se décompose ainsi :The movement breaks down as follows:

D'abord, le premier chariot se déplace vers l'extérieur, alors que le vantail reste bloqué longitudinalement. Le blocage peut être assuré par un doigt coopérant avec une rampe à l'arrière du vantail. Pendant cette phase, le vantail ne peut que déboîter de l'arrière.First, the first carriage moves outward, while the leaf remains locked longitudinally. Blocking can be ensured by a finger cooperating with a ramp at the back of the leaf. During this phase, the leaf can only move from behind.

Cette situation empêche le déplacement transversal du second chariot pendant le déplacement du premier.This situation prevents the transverse displacement of the second carriage during the movement of the first carriage.

La barre de conjugaison entraîne le maneton muni du galet dans un mouvement de rotation dans lequel il suit la section courbe du chemin de guidage, jusqu'à ce que ce galet rejoigne un segment rectiligne orienté transversalement. Le déplacement du second chariot est alors débloqué.The conjugation bar drives the crankpin provided with the roller in a rotational movement in which it follows the curved section of the guide path, until the roller joins a rectilinear segment oriented transversely. The displacement of the second carriage is then unlocked.

Selon une variante ladite barre de conjugaison est entraînée en rotation par la sortie d'un moto-réducteur.According to one variant, said conjugation bar is rotated by the output of a geared motor.

Selon un mode de mise en oeuvre particulier, le mécanisme d'entraînement comporte un système de vis-écrou entraînant le vantail par l'intermédiaire d'un bras muni d'une fourche coopérant avec l'écrou, l'écrou étant immobilisé en rotation et libre en déplacement transversal par rapport à la fourche. Les paliers de la vis sont fixes par rapport à la caisse.According to a particular embodiment, the drive mechanism comprises a screw-nut system driving the leaf through an arm provided with a fork cooperating with the nut, the nut being immobilized in rotation and free in transverse displacement relative to the fork. The bearings of the screw are fixed relative to the body.

Avantageusement, le mécanisme d'entraînement comporte un moteur à double sortie d'entraînement, l'une entraînant la barre de conjugaison, l'autre entraînant la vis-écrou.Advantageously, the drive mechanism comprises a motor with a double drive output, one driving the conjugation bar, the other driving the screw-nut.

Préférentiellement, l'entraînement de la vis-écrou est activé par l'augmentation du couple sur la sortie d'entraînement de la barre de conjugaison.Preferably, driving the screw-nut is activated by increasing the torque on the drive output of the conjugation bar.

Selon une variante, le mécanisme d'entraînement assure en outre le déplacement vertical d'une tringle de liaison commandant le mécanisme de guidage et de verrouillage inférieur du vantail.Alternatively, the drive mechanism further ensures the vertical movement of a connecting rod controlling the guiding mechanism and lower locking of the leaf.

Avantageusement, le mécanisme de guidage inférieur comporte un chariot mobile transversalement comportant à son extrémité extérieure un galet coopérant avec un chemin de guidage prévu sur le vantail, ledit chariot mobile étant commandé par un système de bielle-manivelle actionné par ladite tringle de liaison.Advantageously, the lower guide mechanism comprises a transversely movable carriage having at its outer end a roller cooperating with a guide path provided on the leaf, said movable carriage being controlled by a connecting rod-crank system actuated by said connecting rod.

De préférence, système de bielle-manivelle comporte une bielle présentant à une extrémité une articulation coopérant avec le chariot, et à l'autre extrémité une articulation coopérant avec un maneton pivotant par rapport à un axe longitudinal solidaire de la caisse, le maneton comportant en outre une articulation avec la tringle de liaison.Preferably, a connecting rod-crank system comprises a connecting rod having at one end a hinge cooperating with the carriage, and at the other end a hinge cooperating with a pin crank pivotally relative to a longitudinal axis integral with the body, the crank pin comprising in addition to an articulation with the connecting rod.

Selon un mode de réalisation préféré, la droite passant par l'articulation bielle-chariot d'une part et l'articulation bielle-maneton est décalée par rapport audit axe solidaire de la caisse, en position de fermeture.According to a preferred embodiment, the straight line passing through the link-trolley articulation on the one hand and the connecting rod-crank joint is offset with respect to said integral axis of the body, in the closed position.

Selon une réalisation particulière, la tringle de liaison entraîne en outre la serrure centrale.According to a particular embodiment, the connecting rod also causes the central lock.

Selon une autre variante, la partie avant du vantail présente une encoche d'encastrement dans une partie protubérante liée à la caisse.According to another variant, the front part of the leaf has a recess notch in a protruding part connected to the body.

Structure générale de la porteGeneral structure of the door

La porte coulissante selon l'exemple de réalisation de l'invention décrite dans ce qui suit comporte un vantail mobile par rapport à un cadre (100) fixé sur la caisse rentrant dans la lumière de la caisse d'une rame ferroviaire.The sliding door according to the embodiment of the invention described in the following comprises a leaf movable relative to a frame (100) fixed on the body entering the light of the box of a train train.

La liaison entre les montants de la caisse et le cadre est réalisée de manière connue par des potences (101 à 104). Le cadre sert à positionner les serrures (300, 400).The connection between the amounts of the box and the frame is made in a known manner by brackets (101 to 104). The frame serves to position the locks (300, 400).

Le cadre comporte en partie basse le guidage bas selon une cinématique « coulissante louvoyante » prévoyant le déboîtement du vantail par un pivotement du vantail assurant le déplacement vers l'extérieur de la partie arrière du vantail dans un premier temps, puis le déplacement vers l'extérieur de la partie avant du vantail.The frame comprises in the lower part the low guide according to a kinematic "slidable sliding" providing the disengagement of the leaf by a pivoting of the leaf ensuring the outward movement of the rear part of the leaf in a first step, then the movement to the outside the front part of the leaf.

Dès que l'arrière du vantail est déboîté, le chariot avant se déplace transversalement vers l'extérieur pendant que le vantail se déplace obliquement. Lorsque le vantail est à nouveau dans un plan parallèle à la position occupée lors de la fermeture le vantail continu à se déplacer vers l'arrière par un mouvement de translation longitudinal.As soon as the back of the leaf is dislodged, the front carriage moves transversely outwards while the leaf moves obliquely. When the leaf is again in a plane parallel to the position occupied during closing the leaf continues to move backwards by a longitudinal translational movement.

Le guidage du vantail est assuré par un rail solidaire de la caisse assurant le guidage d'un galet solidaire du vantail.The guiding of the leaf is ensured by a rail integral with the box ensuring the guiding of a roller secured to the leaf.

En position de fermeture, le vantail est encastré à l'avant sur la caisse par une encoche avec jeu pour permettre la pénétration d'un doigt solidaire du cadre.In the closed position, the leaf is recessed at the front on the body by a notch with clearance to allow the penetration of a finger secured to the frame.

Alternativement, cet encastrement peut être assuré par une butée avec une rampe montée sur la caisse, coopérant avec un galet prévu sur la partie avant de la porte.Alternatively, this recess can be provided by a stop with a ramp mounted on the body, cooperating with a roller provided on the front part of the door.

Le mécanisme d'entraînement du vantail comprend un moteur (201) entraînant une vis filetée (17) ainsi que la barre de conjugaison (9). La vis filetée (17) commande le déplacement des deux chariots (3, 3bis). Le fonctionnement de la barre de conjugaison (9) sera décrit ci-après.The drive mechanism of the leaf comprises a motor (201) driving a threaded screw (17) and the conjugation bar (9). The threaded screw (17) controls the movement of the two carriages (3, 3bis). The operation of the conjugation bar (9) will be described below.

Mécanisme en partie hauteMechanism at the top

Ce mécanisme (200) est constitué par une plaque de base sur laquelle les principaux sous-ensembles suivants sont montés :

  • un système de suspension
  • Un système de guidage et de conjugaison
  • Un système d'entraînement et de motorisation
  • Un système de verrouillage.
This mechanism (200) is constituted by a base plate on which the following main subassemblies are mounted:
  • a suspension system
  • A guidance and conjugation system
  • A drive system and motorization
  • A locking system.

Le système de suspension est composé d'un élément robuste et fiable qui a pour fonction de supporter le poids du vantail ainsi que les efforts de fermeture nécessaires pour commander et bloquer le mécanisme.The suspension system is composed of a robust and reliable element whose function is to support the weight of the leaf as well as the closing forces necessary to control and lock the mechanism.

Il comprend un tube (2) disposé longitudinalement, le long du bord supérieur de l'ouverture de la caisse. Le vantail est équipé d'un bras de suspension (1). Le bras de suspension (1) est équipé d'un galet (7) qui se déplace à l'intérieur d'un rail de guidage (8) fixé à la plaque de base (elle-même liée à la caisse). Ce dispositif, associé à la barre de conjugaison horizontale (9), permet d'assurer la cinématique du bras d'entraînement (1). La barre de conjugaison horizontale (9) est elle aussi fixée à la plaque de base grâce à des supports (10).It comprises a tube (2) arranged longitudinally along the upper edge of the opening of the box. The leaf is equipped with a suspension arm (1). The suspension arm (1) is equipped with a roller (7) which moves inside a guide rail (8) fixed to the base plate (itself linked to the body). This device, associated with the horizontal conjugation bar (9), ensures the kinematics of the drive arm (1). The horizontal conjugation bar (9) is also fixed to the base plate by means of supports (10).

La barre de conjugaison (9) est une barre de torsion horizontale dont les extrémités sont montées sur des supports (10) fixés à la plaque base. Afin de pouvoir tourner librement la barre (9) est montée sur les supports (10) par l'intermédiaire de roulements.The conjugation bar (9) is a horizontal torsion bar whose ends are mounted on supports (10) fixed to the base plate. In order to freely rotate the bar (9) is mounted on the supports (10) by means of bearings.

La barre de conjugaison (9) peut réaliser avec la même rotation des mouvements différenciés de ses deux extrémités. Une des extrémités sera équipée de l'axe (11) et de la bielle articulée (12) sur le chariot de suspension (3). L'autre extrémité sera munie d'une bielle équipée (12 bis), d'un galet (13) qui se déplace sur un chemin de guidage (14) fixée à l'autre chariot de suspension (3 bis). Lorsque le mouvement de translation du bras de suspension (1) ou du vantail est bloqué, la rotation de la barre de conjugaison (9) fait déplacer (grâce à la bielle articulée) le chariot (3) de l'extrémité bloquée pendant qu'à l'autre extrémité, grâce à la géométrie du chemin de guidage (14) et grâce au blocage longitudinal du bras de suspension du vantail ou de son bras de suspension, le galet (13) peut tourner sans que le chariot (3 bis) se déplace.The conjugation bar (9) can perform with the same rotation differentiated movements of its two ends. One of the ends will be equipped with the axis (11) and the articulated link (12) on the suspension carriage (3). The other end will be provided with a fitted rod (12a), a roller (13) which moves on a guide path (14) attached to the other suspension carriage (3a). When the translation movement of the suspension arm (1) or the leaf is blocked, the rotation of the conjugation bar (9) causes the carriage (3) of the blocked end to move (thanks to the articulated link) while at the other end, thanks to the geometry of the guide path (14) and thanks to the longitudinal locking of the leaf suspension arm or its suspension arm, the roller (13) can rotate without the carriage (3a) moves.

Quand la rotation de la barre de conjugaison (9) est arrivée à la fin de son parcours, un des chariots de suspension (3) s'est totalement déplacé et l'autre (3 bis) n'a pas encore commencé son mouvement. Dans cette position, une des deux extrémités s'est totalement déplacée et le bras (1) lié au vantail peut alors se déplacer longitudinalement suivant le guidage (8) fixé à caisse et permettre que le chariot de suspension (3 bis) qui était fixe, puisse se déplacer. En effet, le galet (13) de la bielle (12 bis) de la barre de conjugaison (9) est alors en vis-à-vis de la rainure horizontale du chemin de guidage (14) ce qui permet son mouvement.When the rotation of the conjugation bar (9) has reached the end of its course, one of the suspension carriages (3) has moved completely and the other (3a) has not yet begun its movement. In this position, one of the two ends has moved completely and the arm (1) connected to the leaf can then move longitudinally along the guide (8) fixed to cash and allow the suspension carriage (3 bis) which was fixed , can move. Indeed, the roller (13) of the rod (12a) of the conjugation bar (9) is then vis-à-vis the horizontal groove of the guide path (14) which allows its movement.

Entraînement et motorisationTraining and motorization

L'entraînement du bras de suspension (1) se réalise à travers un système de fourche, articulée (15) sur ce bras et qui est lié à l'écrou (18) du système "vis de commande" (17). La vis de commande (17) est un axe fileté avec un pas déterminé sur lequel s'engraine un écrou (18) avec le même pas. Cet écrou (18) est équipé de deux plans qui, montés sur la fourche (15), empêchent la rotation de l'écrou (18), ainsi la rotation de la vis (17) est transformée en un déplacement de l'écrou (18) et en même temps du bras (1) et du vantail. Cet effort de translation est transmis à la fourche (15) à travers un galet (16) fixé à l'écrou (18) et c'est la fourche articulée qui absorbe grâce à sa forme le déplacement du bras d'entraînement (1). Le système de vis de commande (17) est monté grâce à deux supports d'extrémité (10) fixés à la plaque base du mécanisme. Ces supports (10) sont les mêmes que ceux qui servent de fixation à la barre de conjugaison horizontale (9). Sur une des extrémités de la vis de commande (17) une roue dentée est montée (19). Le pignon d'entraînement de l'ensemble moteur électrique (20) engrène sur cette roue dentée (19).The drive of the suspension arm (1) is carried out through an articulated fork system (15) on this arm and which is connected to the nut (18) of the "control screw" system (17). The control screw (17) is a threaded shaft with a determined pitch on which a nut (18) engages with the same pitch. This nut (18) is equipped with two planes which, mounted on the fork (15), prevent the rotation of the nut (18), thus the rotation of the screw (17) is transformed into a displacement of the nut ( 18) and at the same time the arm (1) and the leaf. This translational force is transmitted to the fork (15) through a roller (16) fixed to the nut (18) and it is the articulated fork which absorbs, thanks to its shape, the displacement of the drive arm (1). . The control screw system (17) is mounted by means of two end supports (10) fixed to the base plate of the mechanism. These supports (10) are the same as those which serve to fix the horizontal conjugation bar (9). On one end of the control screw (17) a toothed wheel is mounted (19). The drive gear of the electric motor assembly (20) meshes with this toothed wheel (19).

L'ensemble moteur électrique (20) est installé à une des extrémités et est fixé à la caisse grâce au même support (10) de la vis de commande (17) et de la barre de conjugaison horizontale (9).The electric motor assembly (20) is installed at one end and is fixed to the body by the same support (10) of the control screw (17) and the horizontal bar (9).

L'ensemble moteur électrique (20) est constitué par un moto-réducteur équipé d'un moteur électrique de courant continu à aimants permanents et d'un réducteur à planétaires.The electric motor assembly (20) is constituted by a geared motor equipped with an electric motor of direct current with permanent magnets and a planetary gearbox.

Le réducteur est fixé au corps du moteur électrique grâce à des roulements qui lui donnent un degré de liberté supplémentaire par rapport au moteur électrique (20) et ceci permet d'avoir deux sorties d'entraînement différentes. Ainsi d'une part, le corps du réducteur est équipé d'une roue dentée qui engrène avec la couronne dentée (19) de la vis de commande (17) et d'autre part l'axe de sortie du réducteur est équipé d'un pignon denté (21) qui engrène avec la roue dentée (11) de la barre de conjugaison horizontale (9). Cette roue dentée (11) sert en même temps de bielle latérale ; c'est sur elle qu'est fixé l'axe sur lequel s'articule la bielle d'entraînement (12) du support de suspension (3).The gearbox is attached to the body of the electric motor through bearings that give it an additional degree of freedom from the electric motor (20) and this allows to have two different drive outputs. Thus, on the one hand, the body of the gearbox is equipped with a gear which meshes with the ring gear (19) of the control screw (17) and on the other hand the output shaft of the gearbox is equipped with a toothed gear (21) which meshes with the toothed wheel (11) of the horizontal conjugation bar (9). This toothed wheel (11) serves at the same time as a lateral rod; it is on it that is fixed the axis on which articulates the drive rod (12) of the suspension support (3).

La porte étant fermée, le vantail de la porte est bloqué en translation grâce à un système associant un galet et une rampe empêchant la translation.The door being closed, the leaf of the door is blocked in translation by a system associating a roller and a ramp preventing translation.

Quand le moteur électrique (20) est alimenté, l'extérieur du réducteur qui engendre la traction de la vis de commande (17) ne peut pas tourner puisque la porte est bloquée en sens longitudinal et c'est l'axe de sortie du réducteur qui tourne, provoquant la rotation de la barre de conjugaison (9) et donc le déplacement du chariot de suspension associé (3). Lorsque le vantail devient libre et que la rotation de la barre de conjugaison (9) arrive en butée alors l'extérieur du réducteur peut tourner provoquant l'action de la vis (17) sur l'écrou (18) qui à son tour va motoriser le bras d'entraînement (1) et son vantail associé, faisant sortir l'autre extrême du tube de suspension (2).When the electric motor (20) is energized, the outside of the gearbox which causes the traction of the control screw (17) can not turn since the door is locked in the longitudinal direction and it is the output axis of the gearbox which rotates, causing the rotation of the conjugation bar (9) and thus the displacement of the associated suspension carriage (3). When the leaf becomes free and the rotation of the conjugation bar (9) abuts then the outside of the gear can rotate causing the action of the screw (17) on the nut (18) which in turn goes motorize the drive arm (1) and its associated leaf, bringing out the other end of the suspension tube (2).

VerrouillageLocking

Le verrouillage du mécanisme est réalisé par un système d'arc-boutement produit par la disposition de l'axe et de la bielle articulée (12) placés sur la roue dentée (11) de la barre de conjugaison horizontale (9). Ce système empêche que les efforts appliqués vers l'extérieur provoquent le déplacement du tube de suspension (2).The locking mechanism is achieved by a bracing system produced by the arrangement of the axis and the link rod (12) placed on the toothed wheel (11) of the horizontal bar conjugation (9). This system prevents the forces applied to the outside causing the displacement of the suspension tube (2).

Ce système permet de réaliser tout type de cinématiques « parallèles » ou « non parallèles » en assurant toujours la position verrouillée grâce au passage du point d'arc-boutement de la barre de conjugaison horizontale; en même temps on peut utiliser la rotation de cette bielle pour actionner grâce à une barre verticale le guidage inférieur du vantail et d'éventuelles serrures.This system makes it possible to perform any type of "parallel" or "non-parallel" kinematics by always ensuring the locked position by passing the bracing point of the horizontal conjugation bar; at the same time it is possible to use the rotation of this connecting rod to actuate, thanks to a vertical bar, the lower guide of the leaf and any locks.

Il faut souligner que le système de mouvement différentiel, c'est à dire le fait que l'extrémité avant de la porte a un mouvement différent de l'extrémité postérieure (à l'ouverture c'est la partie postérieur qui sort la première puis la partie avant ensuite, et lors de la fermeture c'est la partie avant qui entre la première puis la partie postérieur ensuite), donne plus de facilités lorsqu'il y a à supporter de grandes charges sur la porte puisque la partie avant reste encastrée sur des points d'ancrage implantés sur la caisse (les efforts ne passent pas par le mécanisme) et que la partie postérieure est bloquée par l'arc-boutement du mécanisme, par l'arc-boutement du guidage inférieur et s'il est nécessaire par une serrure centrale qui sera pilotée en même temps par la barre de conjugaison du mécanisme.It should be emphasized that the system of differential movement, ie the fact that the front end of the door has a different movement from the posterior end (at the opening it is the posterior part that leaves the first and then the front part then, and when closing is the front part which enters the first then the posterior part later), gives more facilities when there is to bear large loads on the door since the front part remains embedded on anchoring points located on the body (the forces do not pass through the mechanism) and that the rear part is blocked by the bracing of the mechanism, by the bracing of the lower guide and if it is required by a central lock that will be controlled at the same time by the mechanism of the bar conjugation.

La serrure centrale à l'arrière de la porte est réalisée sous la forme d'un crochet (50) rétractable commandé par une tringle (51) solidaire du guidage bas. Le crochet (50) verrouille la porte transversalement.The central lock at the back of the door is in the form of a retractable hook (50) controlled by a rod (51) secured to the bottom guide. The hook (50) locks the door transversely.

La partie inférieure de la porte est actionnée par un mécanisme représenté en figure 8. Il comprend un chariot (55) mobile transversalement, actionné par des tringles (57, 58) reliant le mécanisme de la partie supérieure (200) à un mécanisme à arc-boutant (59) assurant la sortie et la rentrée de la partie arrière du vantail.The lower part of the door is actuated by a mechanism represented in figure 8 . It comprises a trolley (55) movable transversely, actuated by rods (57, 58) connecting the mechanism of the upper part (200) to a buttress mechanism (59) ensuring the exit and retraction of the rear part of the leaf.

Ce système est adapté pour monter différents types d'étanchéité de vantail, soit des joints statiques, soit des joints gonflables.This system is suitable for mounting different types of leaf seals, either static seals or inflatable seals.
