Description

La présente invention concerne un dispositif d'entraínement de porte coulissante d'un véhicule automobile, du type comportant un organe mécanique de transmission d'un couple fourni par un moteur asservi, ledit organe et ledit moteur étant disposés au moins en partie intérieurement au véhicule, et un élément de traction souple situé extérieurement au véhicule et auquel est relié la porte par l'intermédiaire d'un chariot déplaçable dans un rail d'entraínement, ledit rail délimitant un contour extérieur de maintien sur une partie de carrosserie du véhicule.The present invention relates to a drive device for sliding door of a motor vehicle, of the type comprising a member mechanical transmission of a torque supplied by a servo motor, said motor member and said motor being arranged at least partially internally at vehicle, and a flexible traction element located outside the vehicle and to which the door is connected by means of a trolley movable in a drive rail, said rail delimiting an external holding contour on a part of the vehicle body.

De tels dispositifs équipent les véhicules à une ou plusieurs portes coulissantes, souvent disposées latéralement au véhicule. L'ouverture et la fermeture automatisées de portes équipées d'un de ces dispositifs constituent un avantage en terme de confort et de sécurité.Such devices equip vehicles with one or more doors sliding, often arranged laterally to the vehicle. The opening and the automatic closing of doors fitted with one of these devices constitutes an advantage in terms of comfort and safety.

Cependant, la plupart de ces dispositifs occupe des volumes très importants, tant à l'intérieur qu'à l'extérieur de la carrosserie du véhicule. Ainsi, il est fréquent que les organes moteurs et de transmission du couple s'étendent largement à l'intérieur de l'habitacle, tandis que le stockage des longueurs inactives du ou des éléments de traction, comme des câbles, nécessite des systèmes encombrants montés plus ou moins totalement en saillie sur l'extérieur du véhicule, lui conférant un aspect extérieur en rupture avec le style général de la carrosserie.However, most of these devices occupy very large volumes. important, both inside and outside the vehicle body. Thus, it is frequent that the motor and transmission organs of the torque extend widely inside the passenger compartment, while the storage of inactive lengths of the traction element (s), such as cables, requires bulky systems mounted more or less completely projecting on the outside of the vehicle, giving it a broken exterior appearance with the general style of the body.

Par ailleurs, ces dispositifs nécessitent un montage complexe en raison de la fixation d'un grand nombre d'éléments d'entraínement et de guidage de l'élément de traction et/ou de la porte, au niveau d'emplacements souvent difficiles d'accès tant à l'intérieur qu'à l'extérieur de la carrosserie. Le réglage de tels dispositifs s'en trouve compromis et il convient par conséquent de prendre en compte toutes les contraintes de montage dès la conception de la carrosserie du véhicule. Les problèmes d'étanchéité et d'usure restent également très prononcés.Furthermore, these devices require complex assembly in reason for fixing a large number of drive elements and guiding the traction element and / or the door, at the level often difficult to access, both inside and outside the body. The adjustment of such devices is compromised and it should therefore take into account all the constraints of mounting from the design of the vehicle body. The problems sealing and wear also remain very pronounced.

Un des objectifs de la présente invention est de proposer un dispositif compact, adaptable sur tous les types de véhicules déjà existants équipés d'au moins une porte latérale coulissante, et dont le montage soit simple et sans réglage. One of the objectives of the present invention is to propose a device compact, adaptable to all types of existing vehicles fitted with at least one sliding side door, the mounting of which is simple and without adjustment.

A cet effet, l'invention a pour objet un dispositif du type précité, et qui comporte, à une extrémité du rail, un organe d'entraínement réversible de l'élément de traction, relié à l'organe de transmission, et, à l'autre extrémité du rail, un organe de renvoi de l'élément de traction.To this end, the invention relates to a device of the aforementioned type, and which comprises, at one end of the rail, a reversible drive member of the traction element, connected to the transmission member, and, at the other end of the rail, a member for returning the traction element.

Sur la figure 1 est représenté un véhicule 1 disposant d'une porte latérale coulissante 2, cette porte étant dans une position partiellement ouverte.In Figure 1 is shown a vehicle 1 having a door sliding side 2, this door being in a partially open position.

Le véhicule 1 représenté est grandement schématisé et ne constitue qu'un exemple illustratif. L'invention s'applique à tout véhicule roulant disposant d'au moins une porte coulissante, que ce véhicule soit à caractère utilitaire ou d'agrément. De même, dans tout ce qui suit, l'exemple développé s'appuiera sur une disposition de la porte coulissante au niveau du flanc droit du véhicule, mais l'invention s'applique évidemment à une porte coulissante disposée sur le flanc opposé du véhicule. Enfin, les coulissements envisagés s'effectuent dans une direction orientée de l'avant vers l'arrière du véhicule (c'est-à-dire de droite à gauche sur la figure 1) en ce qui concerne l'ouverture de la porte, et de l'arrière vers l'avant en ce qui concerne la fermeture de la porte. Bien entendu, l'orientation de ces mouvements de coulissement peut être inversée pour des véhicules de conception différente. The vehicle 1 shown is greatly diagrammed and does not constitute than an illustrative example. The invention applies to any rolling vehicle having at least one sliding door, whether this vehicle is of character utility or amenity. Likewise, in all that follows, the example developed will rely on a sliding door arrangement at the side vehicle right but the invention obviously applies to a sliding door arranged on the opposite side of the vehicle. Finally, the slides envisaged take place in a direction oriented from front to rear of the vehicle (i.e. from right to left in Figure 1) with regard to opening the door, and from the back to the front for closing Door. Of course, the orientation of these sliding movements can be reversed for vehicles of different design.

La porte coulissante 2 est fixée sur le véhicule 1 au niveau de trois emplacements d'appui, chacun d'eux coulissant dans un rail correspondant. Ainsi, un rail supérieur 4 est monté sur la zone supérieure de la carrosserie au niveau du toit du véhicule, par exemple au-dessus des vitres latérales. De même, un rail inférieur 6 est monté sur la zone inférieure de la carrosserie au niveau du plancher du véhicule. Enfin, un rail intermédiaire 8 est disposé entre les rails 4 et 6. La porte 2 est guidée dans chacun de ces rails respectivement au moyen d'un chariot comportant chacun au moins un galet porteur qui roule à l'intérieur du rail. Les chariots des rails supérieur et inférieur sont passifs, subissant l'entraínement de la porte ; ils relèvent de l'art connu. En revanche, le rail intermédiaire 8 forme une zone longitudinale où est entraínée la porte 2 lors de son coulissement, la porte étant supportée par un chariot 10 aménagé suivant l'invention.The sliding door 2 is fixed to the vehicle 1 at three support locations, each of which slides in a corresponding rail. Thus, an upper rail 4 is mounted on the upper zone of the bodywork at vehicle roof level, for example above the windows side. Likewise, a lower rail 6 is mounted on the lower zone of the bodywork at vehicle floor level. Finally, an intermediate rail 8 is arranged between the rails 4 and 6. The door 2 is guided in each of these rails respectively by means of a carriage each comprising at least one carrier roller which rolls inside the rail. The carriages of the upper rails and lower are passive, undergoing the drive of the door; they come under known art. On the other hand, the intermediate rail 8 forms a longitudinal zone where door 2 is driven when it slides, the door being supported by a carriage 10 arranged according to the invention.

Les trois chariots reliant la porte 2 au reste du véhicule 1 sont disposés suivant une forme sensiblement triangulaire, chaque sommet du triangle étant constitué d'un chariot et schématiquement indiqué par les points A, B et C sur la figure 1. Les chariots supérieur (point A) et inférieur (point B) sont fixés intérieurement à la porte, sur sa partie droite, les rails supérieur et inférieur s'étendant alors longitudinalement à l'ouverture délimitée par la porte coulissée en position ouverte. Le chariot intermédiaire 10, schématisé par le point C sur la figure 1, est fixé sur la partie gauche de la porte, le rail associé 8 s'étendant alors sur une partie fixe de carrosserie 12 située dans le prolongement arrière de l'ouverture précitée.The three carriages connecting door 2 to the rest of vehicle 1 are arranged in a substantially triangular shape, each vertex of the triangle consisting of a carriage and schematically indicated by points A, B and C in figure 1. The upper (point A) and lower carriages (point B) are fixed internally to the door, on its right side, the rails upper and lower then extending longitudinally to the defined opening through the sliding door in the open position. The intermediate carriage 10, shown schematically by point C in Figure 1, is attached to the left side of the door, the associated rail 8 then extending over a fixed body part 12 located in the rear extension of the aforementioned opening.

Le dispositif d'entraínement de la porte 2 suivant l'invention est disposé à la fois intérieurement et extérieurement à la carrosserie 12 du véhicule 1. Sur la figure 2 est représentée une partie 14 du dispositif disposée extérieurement, tandis que sur la figure 10 est représentée une autre partie 16 du dispositif disposée intérieurement par rapport à la carrosserie 12 du véhicule.The device for driving the door 2 according to the invention is disposed both internally and externally to the body 12 of the vehicle 1. In Figure 2 is shown a part 14 of the device arranged externally, while in Figure 10 is shown another part 16 of the device arranged internally relative to the body 12 of the vehicle.

Sur la figure 2 sont représentés le rail 8 et le chariot 10 associé. Pour ne pas surcharger le dessin, la porte 2 et la carrosserie 12 du véhicule 1 ne sont pas reproduites. Le rail 8 comporte, dans l'exemple représenté, une première partie d'extrémité 15, sensiblement rectiligne et une seconde partie d'extrémité 17, sensiblement rectiligne et orientée avec un certain angle par rapport à la première partie 14. Les parties 15 et 17 sont reliées par une partie courbe 18 de rail. La partie 15, dans le même plan sensiblement horizontal que les parties de rail 17 et 18, est adaptée pour permettre d'aligner, sensiblement dans le même plan la porte coulissante 2 en position fermée avec l'ensemble des éléments de carrosserie du flanc droit du véhicule 1. Lors de l'ouverture de la porte, la partie de rail 15 permet de dégager la porte 2 du plan précité en l'amenant dans un plan sensiblement parallèle au plan précité, mais à distance vers l'extérieur du véhicule.In Figure 2 are shown the rail 8 and the associated carriage 10. To avoid overloading the design, door 2 and body 12 of the vehicle 1 are not reproduced. The rail 8 comprises, in the example shown, a first end portion 15, substantially rectilinear and a second end part 17, substantially straight and oriented at a certain angle with respect to the first part 14. Parts 15 and 17 are connected by a curved portion 18 of rail. Part 15, in the same plane substantially horizontal as the rail parts 17 and 18, is adapted to allow align the sliding door 2 in substantially the same plane in position closed with all bodywork components on the right side of the vehicle 1. When the door is opened, the rail part 15 makes it possible to release door 2 of the above-mentioned plane by bringing it into a substantially parallel plane on the above plan, but at a distance to the outside of the vehicle.

En coupe transversale, et tel que représenté sur la figure 9, le rail 8 délimite intérieurement un espace 20 d'emprise du chariot 10. En outre, le rail comporte, au-dessous de l'espace d'emprise 20, une paroi 21 dirigée sensiblement vers le bas et dont la forme est aménagée par pliure.In cross section, and as shown in Figure 9, the rail 8 internally delimits a space 20 for the carriage 10. In addition, the rail comprises, below the grip space 20, a wall 21 directed substantially downward and whose shape is arranged by folding.

Le rail 8 épouse la surface extérieure de la carrosserie 12 et définit un encombrement de contour extérieur global 22, représenté en traits mixtes sur la figure 9 et dont la forme coopère avec le contour sensiblement complémentaire de la carrosserie 12. Le rail 8 s'intègre ainsi au mieux à la carrosserie du véhicule, en évitant, vu de l'extérieur, toute saillie anguleuse.The rail 8 follows the exterior surface of the body 12 and defines overall external outline dimensions 22, shown in lines mixed in Figure 9 and whose shape cooperates with the outline substantially complementary to the bodywork 12. The rail 8 thus best integrates with the vehicle body, avoiding, seen from the outside, any angular projection.

Le rail 8 comporte de plus sur sa surface en contact avec la carrosserie 12 plusieurs saillies 23, orientées vers l'intérieur du véhicule et adaptées pour coopérer avec des évidements 24 de forme complémentaire ménagés dans la carrosserie 12. Le rail 8 est maintenu, au moins en partie, au moyen de ces saillies 23 de façon qu'il puisse se démonter et se remonter facilement suivant des aménagements relevant de l'art connu.Rail 8 also has on its surface in contact with the body 12 several projections 23, oriented towards the interior of the vehicle and adapted to cooperate with recesses 24 of complementary shape formed in the bodywork 12. The rail 8 is maintained, at least in part, by means of these projections 23 so that it can be disassembled and reassembled easily following arrangements relating to known art.

Ainsi que représenté sur les figures 2 et 9, le chariot 10 solidaire de la porte 2 comporte une structure de support 25 sur laquelle s'articulent un galet porteur 26 et deux galets guideurs 28. Le galet porteur 26 est monté à rotation libre autour d'un axe 30 sensiblement perpendiculaire à la carrosserie 12 et formé par exemple d'une goupille 32. Les galets guideurs 28, disposés de part et d'autre du galet porteur 26, sont montés à rotation libre autour d'un axe 34 sensiblement vertical, et donc sensiblement perpendiculaire à l'axe 30. Le galet porteur 26 s'appuie sur la surface inférieure de l'espace d'emprise 20, tandis que les galets guideurs 28 s'appuient sur les surfaces latérales de cet espace 20.As shown in Figures 2 and 9, the carriage 10 secured of door 2 has a support structure 25 on which hinge a support roller 26 and two guide rollers 28. The support roller 26 is mounted freely rotating about an axis 30 substantially perpendicular to the body 12 and formed for example of a pin 32. The guide rollers 28, arranged on either side of the support roller 26, are mounted to rotate freely around a substantially vertical axis 34, and therefore substantially perpendicular to the axis 30. The carrier roller 26 rests on the lower surface of the space 20, while the guide rollers 28 rest on the lateral surfaces of this space 20.

Le chariot 10 est relié à un élément de traction 36 adapté pour entraíner le chariot 10 dans le rail 8 de façon réversible. Cet élément 36 est représenté sur les figures sous la forme d'un câble à âme métallique et de section sensiblement circulaire, mais cet élément peut également être constitué d'une courroie, d'une bande ajourée ou d'un câble crémaillère par exemple. Les deux extrémités de ce câble 36 sont fixées sur le chariot 10, au niveau d'une barrette de liaison 38. Cette barrette s'étend entre les deux galets guideurs 28 et est fixée au niveau de l'axe 34 de chacun d'eux. Les deux extrémités du câble 36 sont solidairement fixées à la barrette 38, chacune en un emplacement d'accrochage 38A, 38B au moyen d'attaches.The carriage 10 is connected to a traction element 36 adapted for drive the carriage 10 in the rail 8 reversibly. This item 36 is shown in the figures in the form of a cable with a metallic core and substantially circular section, but this element can also be formed a belt, an openwork band or a rack cable by example. The two ends of this cable 36 are fixed to the carriage 10, at a connecting bar 38. This bar extends between the two guide rollers 28 and is fixed at the level of the axis 34 of each of them. The two ends of the cable 36 are securely attached to the bar 38, each in an attachment location 38A, 38B by means of fasteners.

Le câble 36 s'étend donc en partie à l'intérieur de l'espace d'emprise 20 du rail 8, formant ainsi deux parties d'extrémité supérieures 36A et 36B depuis les emplacements d'accrochage respectifs 38A et 38B jusqu'à l'extrémité du rail correspondante où il est agencé suivant des aménagements détaillés ci-après. Le câble 36 s'étend en retour au-dessous et tout le long du rail 8, formant ainsi un brin inférieur 36C. Le brin inférieur 36C est disposé à l'intérieur d'une cavité 39 longitudinale ménagée inférieurement entre la paroi pliée 21 du rail et la surface de la carrosserie 12.The cable 36 therefore partly extends inside the space 20 of rail 8, thus forming two upper end parts 36A and 36B from the respective hanging locations 38A and 38B to the end of the corresponding rail where it is arranged according to arrangements detailed below. The cable 36 extends back below and all along the rail 8, thus forming a lower strand 36C. The lower strand 36C is arranged inside a longitudinal cavity 39 formed at the bottom between the folded wall 21 of the rail and the surface of the body 12.

Tel que représenté sur la figure 9, à l'intérieur de cette cavité 39, au moins un élément de guidage 40 est fixé sur la paroi inférieure du rail 8 de manière à faciliter le coulissement du brin inférieur 36C. Au niveau de la partie courbée 18 du rail 8, au moins un élément de guidage 40 facilite ce coulissement lors du changement de direction imposé par la courbure du rail. La paroi pliée 21 dissimule ainsi le brin inférieur 36C et les éléments de guidage 40.As shown in FIG. 9, inside this cavity 39, at least one guide element 40 is fixed to the bottom wall of the rail 8 so as to facilitate the sliding of the lower strand 36C. At the level of curved portion 18 of the rail 8, at least one guide element 40 facilitates this sliding during the change of direction imposed by the curvature of the rail. The folded wall 21 thus conceals the lower strand 36C and the elements of guide 40.

A l'extrémité arrière du rail 8 est disposé un organe 41 de renvoi du câble 36 représenté en détail sur la figure 3.At the rear end of the rail 8 is arranged a return member 41 of the cable 36 shown in detail in FIG. 3.

Cet organe 41 comporte une poulie 42 montée à rotation libre autour d'un axe 44, sensiblement confondu sur la figure 3 avec l'axe d'une bague entretoise 46. L'organe 41 comporte également un pontet 48, coaxial à la poulie 42 et s'appuyant contre cette poulie, avantageusement par l'intermédiaire d'un palier 50 disposé entre le pontet et la poulie. Le pontet 48 est monté à translation suivant la direction longitudinale de l'extrémité du rail 17 associée. Le palier 50 assure un guidage en rotation de la poulie 42.This member 41 includes a pulley 42 mounted for free rotation around an axis 44, substantially coincident in FIG. 3 with the axis of a ring spacer 46. The member 41 also includes a bridge 48, coaxial with the pulley 42 and pressing against this pulley, advantageously by via a bearing 50 disposed between the trigger guard and the pulley. Trigger guard 48 is mounted in translation in the longitudinal direction of the end of the associated rail 17. The bearing 50 provides rotational guidance for the pulley 42.

Le câble 36 est enroulé d'un demi-tour sur la poulie 42, le brin inférieur 36C s'étendant depuis le point d'enroulement inférieur du câble sur la poulie et la partie d'extrémité 36B du câble s'étendant depuis le point d'enroulement supérieur.The cable 36 is wound half a turn on the pulley 42, the lower strand 36C extending from the lower cable winding point on the pulley and the end portion 36B of the cable extending from the point upper winding.

L'organe comporte un ressort 51 disposé contre le pontet 48, le ressort 51 étant monté comprimé. Ce ressort 51 et le pontet 48 définissent au moins en partie des moyens de tension du câble 36.The member comprises a spring 51 disposed against the trigger guard 48, the spring 51 being mounted compressed. This spring 51 and the trigger guard 48 define at least in part the cable tensioning means 36.

Les éléments de l'organe 41 précédemment décrits sont agencés à l'intérieur d'un boítier 52 formé de deux parties monobloc juxtaposées. Ce boítier 52 comporte un anneau 53 sur lequel est enfilé en partie le ressort 51. Ce boítier est pourvu de plus de nervures de renfort 54, dont certaines coopèrent avec des nervures associées 56 dont est pourvu le pontet 48 lorsque le boítier 52 est fermé au moyen de la bague 46.The elements of the member 41 previously described are arranged inside a box 52 formed of two juxtaposed one-piece parts. This housing 52 includes a ring 53 on which the spring is partially threaded 51. This housing is provided with more reinforcing ribs 54, some of which cooperate with associated ribs 56 with which the trigger guard 48 is provided when the housing 52 is closed by means of the ring 46.

L'organe 41 comporte de plus une butée 58 en matériau élastique à fort pourvoir d'adsorption de chocs. Cette butée 58 est placée sur la face du boítier 52 orientée vers l'extrémité du rail 17 et est adaptée pour subir un contact de type choc avec le chariot 10.The member 41 further comprises a stop 58 made of elastic material with strong impact adsorption. This stop 58 is placed on the face of the housing 52 oriented towards the end of the rail 17 and is adapted to undergo a shock type contact with the carriage 10.

A l'extrémité avant du rail 8 est disposé un organe 61 d'entraínement du câble 36 représenté en détail sur la figure 5.At the front end of the rail 8 is arranged a member 61 cable drive 36 shown in detail in Figure 5.

Cet organe 61 comporte un carter de protection 62, réalisé en deux parties juxtaposées, solidarisées entre elles et à la carrosserie du véhicule 1 au moyen d'éléments de fixation non représentés empruntant les perforations 64 ménagées dans le carter 62.This member 61 comprises a protective casing 62, produced in two juxtaposed parts, secured to each other and to the vehicle body 1 by means of fasteners not shown borrowing the perforations 64 provided in the housing 62.

A l'intérieur du carter 62, l'organe 61 comporte une poulie 66 solidarisée à un arbre de rotation 68 et guidée par des paliers 70. L'arbre 68 est dimensionné de manière à traverser et à dépasser suffisamment la carrosserie 12 afin d'être entraíné depuis l'intérieur du véhicule 1. Des joints d'étanchéité, comme le joint 72, sont disposés sur l'arbre 68 et en pression sur le boítier 64. Inside the casing 62, the member 61 comprises a pulley 66 secured to a rotation shaft 68 and guided by bearings 70. The shaft 68 is dimensioned so as to pass through and exceed the body sufficiently 12 to be driven from inside the vehicle 1. Seals like the seal 72, are arranged on the shaft 68 and under pressure on the housing 64.

La partie cylindrique de la poulie 66 possède une surface aménagée sur laquelle sont enroulés 3,5 enroulements du câble 36. Comme il est représenté sur la figure 6, le profil, en coupe longitudinale, de cette partie cylindrique de la poulie 66 est concave, ce qui ménage une surface 74 creusée sur laquelle les enroulements du câble 36 se répartissent de manière jointive et sans chevauchement. La poulie 66 reçoit à son point d'enroulement supérieur la partie d'extrémité 36A du câble et à son point d'enroulement inférieur le brin retour 36C, ces points d'enroulement supérieur et inférieur étant situés du même côté dirigé vers l'extrémité du rail 15.The cylindrical part of the pulley 66 has a fitted surface on which are wound 3.5 windings of the cable 36. As it is shown in Figure 6, the profile, in longitudinal section, of this part cylindrical pulley 66 is concave, which saves a hollow 74 surface on which the cable windings 36 are distributed so contiguous and without overlap. Pulley 66 receives at its point upper winding end portion 36A of the cable and at its point of lower winding the return strand 36C, these upper winding points and lower being located on the same side directed towards the end of the rail 15.

Sur la figure 10 est représentée la partie 16 du dispositif suivant l'invention disposée intérieurement à la carrosserie 12 du véhicule 1.In Figure 10 is shown part 16 of the following device the invention arranged inside the body 12 of the vehicle 1.

Cette partie 16 est d'architecture variable selon le véhicule sur lequel elle est agencée de façon qu'elle occupe des volumes rendus inutilisables et/ou dans les épaisseurs creuses de la caisse du véhicule.This part 16 is of variable architecture depending on the vehicle on which it is arranged so that it occupies unusable volumes and / or in the hollow thicknesses of the vehicle body.

Dans l'exemple représenté sur la figure 10, la partie 16 comporte une platine 80 formant la structure de support des autres pièces de la partie 16 et délimitant les points (non représentés) de fixation à la caisse du véhicule 1.In the example shown in Figure 10, part 16 includes a plate 80 forming the support structure of the other parts of the part 16 and delimiting the points (not shown) for attachment to the vehicle body 1.

Cette platine 80 est pourvue d'une bague de frottement 82 sur laquelle est agencée une poulie 84. La poulie 84 est montée sur l'arbre 68 de l'organe 61 d'entraínement du câble 36 ; seul l'axe de l'arbre 68 a été reporté sur la figure 10.This plate 80 is provided with a friction ring 82 on which a pulley 84 is arranged. The pulley 84 is mounted on the shaft 68 of the cable drive member 61; only the axis of the shaft 68 has been carried over in figure 10.

La platine 80 supporte à la fois un moto-réducteur 86 et un boítier électronique 88 de commande de ce moteur 86 et d'interface avec l'électronique du véhicule 1. Ces éléments 86 et 88 ne sont représentés que très schématiquement puisqu'ils ne relèvent pas de l'invention, mais de l'art connu. L'axe de l'arbre de sortie du moto-réducteur 86 est noté 90, étant entendu que la disposition et les aménagements relatifs à cet arbre optimisent l'utilisation d'espaces inutilisables.The plate 80 supports both a geared motor 86 and a housing electronics 88 for controlling this engine 86 and for interfacing with vehicle electronics 1. These elements 86 and 88 are only shown very schematically since they are not a matter of invention, but of art known. The axis of the output shaft of the gear motor 86 is noted 90, being understood that the arrangement and the arrangements relating to this tree optimize the use of unusable space.

Une poulie 92, montée directement sur l'axe 90, est reliée à la poulie 84 par l'intermédiaire d'un élément de transmission de couple 94, représenté sur la figure 10 sous la forme d'une courroie crantée. A pulley 92, mounted directly on the axis 90, is connected to the pulley 84 via a torque transmission element 94, shown in Figure 10 in the form of a toothed belt.

Il est à noter que, lors du montage, il est avantageux d'utiliser un des points de fixation du moto-réducteur 86 comme point de pivotement par rapport aux autres, notamment pour assurer la tension de la courroie 94. Par légère rotation du corps du moteur 86, un rapprochement ou un éloignement des poulies 84 et 92 s'opère, leur entraxe s'en trouvant modifié. Lorsqu'il est ajusté, il suffit de bloquer tour à tour les différents points de fixation du moteur sur la platine 80.It should be noted that, during assembly, it is advantageous to use a fixing points of the gear motor 86 as a pivot point by compared to others, in particular to ensure the tension of the belt 94. By slight rotation of the body of the motor 86, a move in or out pulleys 84 and 92 operate, their center distance being modified. When he is adjusted, it is sufficient to block in turn the various fixing points of the motor on deck 80.

Le fonctionnement du dispositif selon l'invention et qui vient d'être décrit est le suivant.The operation of the device according to the invention and which has just been described is as follows.

Au repos, c'est-à-dire avec la porte 2 immobile en position ouverte ou en position fermée, l'organe 41 de renvoi du câble 36 assure la tension de ce câble puisque le ressort 51, monté initialement dans un état comprimé, exerce en permanence une force de poussée suivant la direction du câble 36 et orientée vers l'arrière du véhicule. Cette force s'applique sur le pontet 48, déplaçant par translation ce dernier, et par conséquent la poulie 42, à l'intérieur du boítier 52, tant que l'intensité de la force antagoniste de tension du câble 36 n'a pas atteint une valeur permettant un équilibrage des forces.At rest, i.e. with door 2 stationary in the open position or in the closed position, the member 41 for returning the cable 36 ensures the tension of this cable since the spring 51, initially mounted in a compressed state, permanently exerts a pushing force in the direction of the cable 36 and oriented towards the rear of the vehicle. This force applies to the trigger guard 48, moving the latter by translation, and consequently the pulley 42, inside the housing 52, as long as the intensity of the opposing force of cable tension 36 has not reached a value allowing balancing of strengths.

Pour décrire le fonctionnement hors-repos du dispositif suivant l'invention, on se place dans le cas où la porte 2 du véhicule 1 s'ouvre, c'est-à-dire est déplacée de la droite vers la gauche sur la figure 1.To describe the out-of-rest operation of the following device the invention, it is placed in the case where the door 2 of the vehicle 1 opens, that is to say is moved from right to left in Figure 1.

L'instruction commandant l'ouverture de la porte est donnée, par exemple par simple pression au niveau d'une poignée 100 de la porte 2. L'électronique du véhicule envoie alors un signal correspondant au boítier de commande 88, qui actionne l'arbre 90 du moto-réducteur 86. Par l'intermédiaire de la courroie crantée 94, la poulie 84 est entraínée et communique le couple moteur à l'arbre 86. Dans l'exemple considéré, l'arbre 86 est entraíné dans le sens indiqué sur la figure 5 par la flèche courbe C.The instruction controlling the opening of the door is given, by example by simply pressing on a handle 100 of door 2. The vehicle electronics then sends a signal corresponding to the box 88, which actuates the shaft 90 of the gear motor 86. By via the toothed belt 94, the pulley 84 is driven and communicates the driving torque at shaft 86. In the example considered, shaft 86 is driven in the direction shown in Figure 5 by the curved arrow C.

L'arbre 68 transmet à la poulie 66 le couple moteur, la poulie 66 entraínant alors par friction le câble tendu 36.The shaft 68 transmits the engine torque to the pulley 66, the pulley 66 entraining then by friction the tensioned cable 36.

Le brin inférieur 36C est en conséquence tiré vers l'avant du véhicule 1, sa progression sous la paroi pliée 21 du rail 8 étant facilitée par les éléments de guidage 40. Etant montée à rotation libre, la poulie 42 de l'organe de renvoi 41 est entraínée en rotation par le câble 36, le brin supérieur 36B étant tiré vers l'arrière du véhicule autour de la poulie 42. Comme l'extrémité 36B du câble est accrochée solidairement à la barrette 38 au niveau de l'emplacement d'accrochage 38B, le chariot 10 est tracté par le câble 36 et se déplace à l'intérieur de l'espace d'emprise 20 du rail 8 vers l'arrière du véhicule 1. Le déplacement du chariot 10 est réalisé par la rotation du galet porteur 26 et le guidage des galets 28. La porte 2 étant solidaire du chariot 10, le mouvement de translation suivant la direction du rail 8 est communiqué à la porte 2, qui coulisse latéralement au véhicule 1, entraínant les chariots supérieur et inférieur qui se déplacent dans les rails respectivement supérieur 4 et inférieur 6.The lower strand 36C is therefore pulled towards the front of the vehicle. 1, its progression under the folded wall 21 of the rail 8 being facilitated by the guide elements 40. Being mounted with free rotation, the pulley 42 of the return member 41 is rotated by the cable 36, the upper strand 36B being pulled towards the rear of the vehicle around the pulley 42. As the end 36B of the cable is fixedly attached to the bar 38 at the level from the hanging location 38B, the carriage 10 is towed by the cable 36 and moves inside the space 20 of the rail 8 towards the rear of the vehicle 1. The movement of the carriage 10 is achieved by rotation of the carrier roller 26 and the guide of the rollers 28. The door 2 being integral of the carriage 10, the translational movement in the direction of the rail 8 is communicated to door 2, which slides laterally to vehicle 1, driving the upper and lower carriages which move in the rails respectively upper 4 and lower 6.

La partie d'extrémité 36A du câble, accrochée solidairement à la barrette 38 au niveau de l'emplacement d'accrochage 38A, est entraíné vers l'arrière du véhicule, en se déroulant de la poulie 66 de l'organe d'entraínement 61.The end portion 36A of the cable, hooked securely to the bar 38 at the hanging location 38A, is driven towards the rear of the vehicle, unwinding from the pulley 66 of the member training 61.

Pendant toute la course d'ouverture de la porte 2, la partie inférieure 36C du câble 36 s'enroule autour de la poulie 66 tandis qu'une autre partie du câble, la partie d'extrémité supérieure 36B, se déroule. La poulie 66 dispose ainsi en permanence de 3,5 enroulements du câble. La surface creusée 74 de la partie cylindrique de la poulie 66 permet d'entraíner par friction le câble, les enroulements successifs disposés le plus à l'extérieur de cette partie, maintenant les autres et évitant les chevauchements.Throughout the opening stroke of door 2, the lower part 36C of cable 36 wraps around pulley 66 while another part of the cable, the upper end part 36B, is unwound. Pulley 66 thus permanently has 3.5 cable windings. The surface hollow 74 of the cylindrical part of the pulley 66 allows to drive by friction the cable, the successive windings arranged outermost of this part, maintaining the others and avoiding overlaps.

Le dispositif suivant l'invention est adaptable sur tout véhicule déjà existant et disposant d'une porte coulissante dans un rail. Le câble 36 d'entraínement de la porte met à profit l'agencement du rail sur la carrosserie, ainsi que les organes d'entraínement 61 et de renvoi 41 qui se logent dans des espaces restreints, uniquement dans le prolongement du contour extérieur 22 du rail 8. En conséquence, le dispositif suivant l'invention est discret et, extérieurement comme intérieurement, s'intègre totalement au véhicule.The device according to the invention is adaptable to any vehicle already existing and having a sliding door in a rail. Cable 36 door drive leverages the arrangement of the rail on the bodywork, as well as the drive members 61 and reference 41 which are housed in tight spaces, only in line with the contour outside 22 of the rail 8. Consequently, the device according to the invention is discreet and, externally and internally, integrates fully into the vehicle.

Par ailleurs, le montage du dispositif est facile. L'organe de renvoi 41 est suffisamment compact pour remplacer un élément butoir, très couramment implanté en bout de course du rail. La tension du câble 36 est automatiquement effectuée au moyen du ressort 51, sans aucun réglage complémentaire, ce qui offre l'avantage de ne pas tenir compte des dispersions géométriques des composants liés à la tension du câble. Quant à la partie du dispositif agencée à l'intérieur de la carrosserie, son aménagement est très souple, notamment pour s'adapter au mieux aux évidements inutilisés de la caisse du véhicule. A cet effet, l'élément de transmission de couple 94 peut être agencé sous la forme d'une chaíne, d'un cardan ou d'une courroie à profil adapté.Furthermore, the mounting of the device is easy. The referral body 41 is compact enough to replace a stopper element, very commonly installed at the end of the rail travel. Cable tension 36 is automatically performed by means of the spring 51, without any additional adjustment, which has the advantage of not taking dispersions into account components of the cable tension components. As for the part of the device arranged inside the body, its arrangement is very flexible, especially to best adapt to unused recesses from the vehicle body. To this end, the torque transmission element 94 can be arranged in the form of a chain, a gimbal or a belt with adapted profile.

De plus, le dispositif offre une bonne fiabilité, les composants les plus vulnérables et les plus sensibles aux agressions de tous types étant disposés à l'intérieur des boítiers protecteurs 52 et 62, éventuellement étanchéifiés.In addition, the device offers good reliability, the components the most vulnerable and most susceptible to assault of all types being arranged inside the protective boxes 52 and 62, possibly sealed.

En variante non représentée au dispositif suivant l'invention, la partie 16 comporte une pièce monobloc et réalisée en polymère remplaçant la platine 80 et le boítier 88. Cette pièce sert alors à la fois de structure rigide et d'enveloppe adaptée à recevoir l'électronique de commande du dispositif.In a variant not shown in the device according to the invention, the part 16 has a single piece made of replacement polymer the plate 80 and the housing 88. This part then serves both as a rigid structure and of an envelope adapted to receive the control electronics of the device.

Sur la figure 4 est représentée une variante de réalisation de l'organe de renvoi 41. Les éléments communs entre les figures 3 et 4 portent les mêmes références, la variante de la figure 4 se distinguant de l'organe 41 de la figure 3 par ce qui suit.In Figure 4 is shown an alternative embodiment of the reference member 41. The common elements between FIGS. 3 and 4 bear the same references, the variant of Figure 4 differing from the body 41 of Figure 3 with the following.

L'ensemble constitué du palier 50, de la poulie 42 et du pontet 48 est remplacé par une demi-poulie 110 d'axe 44 et pourvue d'un orifice central 112 de forme sensiblement oblongue. La demi-poulie 110 comporte de plus des nervures 56 adaptées pour coopérer avec certaines des saillies 54 du boítier 52. La demi-poulie 110 est ainsi montée à translation suivant la direction longitudinale de la partie de rail 17. Le mouvement de translation est commandé comme précédemment par le ressort 51 monté comprimé sur l'anneau 53 et est permis par le jeu important ménagé par l'orifice oblong 112, le ressort 51 et l'orifice 112 formant au moins en partie les moyens de tension du câble 36. Les nervures 56 guident en translation la demi-poulie 110.The assembly consisting of the bearing 50, the pulley 42 and the trigger guard 48 is replaced by a half-pulley 110 of axis 44 and provided with a central hole 112 of substantially oblong shape. The half-pulley 110 has plus ribs 56 adapted to cooperate with some of the projections 54 of the housing 52. The half-pulley 110 is thus mounted in translation along the longitudinal direction of the rail part 17. The translational movement is controlled as before by the spring 51 mounted compressed on the ring 53 and is enabled by the large clearance provided by the oblong orifice 112, the spring 51 and the orifice 112 forming at least partially the means of cable tension 36. The ribs 56 guide the half-pulley in translation 110.

Le fonctionnement du dispositif est analogue à celui explicité précédemment, à la différence que, la demi-poulie 110 ne disposant pas de liberté de mouvement en rotation, le câble 36 s'articule autour de cette demi-poulie 110 uniquement par glissement.The operation of the device is similar to that explained above, with the difference that, the half-pulley 110 not having freedom of rotational movement, the cable 36 is articulated around this half-pulley 110 only by sliding.

Cette variante de réalisation de l'organe de renvoi 41 présente l'avantage d'être encore plus compacte que la précédente, tout en assurant les mêmes fonctions. Elle est donc particulièrement adaptée au véhicule dont l'architecture n'offre qu'une place très restreinte à l'extrémité arrière du rail d'entraínement 8.This variant embodiment of the return member 41 has the advantage of being even more compact than the previous one, while ensuring the same functions. It is therefore particularly suitable for the vehicle whose architecture offers only a very limited place at the rear end of the drive rail 8.

Sur les figures 7 et 8 est représentée une variante de réalisation de l'organe d'entraínement 61. Les éléments communs entre les figures 5 et 6 et respectivement les figures 7 et 8 portent les mêmes références, la variante des figures 7 et 8 se distinguant de l'organe 61 des figures 5 et 6 par ce qui suit. La poulie 66 comporte quatre gorges 120, ménagées suivant une direction sensiblement parallèle à l'axe de la poulie 66 sur la surface 74 de sa partie cylindrique et réparties de manière sensiblement uniforme.In Figures 7 and 8 is shown an alternative embodiment of the drive member 61. The common elements between Figures 5 and 6 and Figures 7 and 8 respectively bear the same references, the variant Figures 7 and 8 differing from the member 61 of Figures 5 and 6 by what follows. The pulley 66 has four grooves 120, arranged in a direction substantially parallel to the axis of the pulley 66 on the surface 74 of its cylindrical part and distributed in a substantially uniform manner.

De plus, le câble 36 est muni, au moins dans sa partie amenée à être enroulée et/ou déroulée autour de la poulie 66, de billes 122 solidarisées au câble et réparties de façon uniforme.In addition, the cable 36 is provided, at least in its part brought to be wound and / or unwound around the pulley 66, balls 122 secured to the cable and evenly distributed.

Dans l'exemple représenté, la poulie 66 comporte quatre gorges 120 et est pourvue de 3,5 enroulements de câble 36, ce dernier comportant une bille 122 tous les ¾ de tour de poulie. Ainsi, au total, cinq billes 122 se trouvent en engrènement sur la poulie 66 et sont toutes indiquées, en trait plein ou en pointillé le cas échéant, sur la figure 7, le câble 36 n'étant pas reproduit pour ne pas surcharger le dessin.In the example shown, the pulley 66 has four grooves 120 and is provided with 3.5 cable windings 36, the latter comprising a ball 122 every ¾ of a pulley turn. Thus, in total, five balls 122 are are meshed with pulley 66 and are all indicated by a line solid or dotted if necessary, in FIG. 7, the cable 36 not being reproduced so as not to overload the drawing.

La répartition des billes sur le câble 36 est réalisée de façon que, tout en conservant le maintien mutuel des enroulements de manière jointive, tout contact entre deux billes est évité. Les frottements et les bruits de fonctionnement sont ainsi minimisés.The distribution of the balls on the cable 36 is carried out so that, while maintaining the mutual maintenance of the windings in a contiguous manner, any contact between two balls is avoided. Frictions and operating noises are thus minimized.

Le fonctionnement du dispositif est analogue à celui expliqué en regard des figures 5 et 6, la variante des figures 7 et 8 présentant l'avantage de développer une plus grande capacité d'entraínement du câble 36.The operation of the device is similar to that explained in look at Figures 5 and 6, the variant of Figures 7 and 8 having the advantage to develop a greater capacity for driving the cable 36.

Une variante non-représentée consiste à munir l'organe de renvoi 41 de la figure 3 d'une poulie à surface creusée 74, comme celle représentée en 66 sur la figure 5 ou la figure 7, avec un nombre d'enroulements de câble variable.A variant not shown consists in providing the return member 41 of FIG. 3 of a hollow surface pulley 74, like that shown at 66 in FIG. 5 or FIG. 7, with a number of windings of variable cable.

Par ailleurs, on comprendra évidemment que le nombre d'enroulements du câble sur la poulie 66 est variable, l'indication de 3, 5 enroulements données plus haut n'ayant qu'une valeur illustrative. Sans sortir du cadre de l'invention, on peut choisir un nombre d'enroulements plus petit ou plus grand.Furthermore, it will obviously be understood that the number of windings of the cable on the pulley 66 is variable, the indication of 3, 5 windings data above having only an illustrative value. Without going out within the scope of the invention, a smaller number of windings can be chosen or larger.

En outre, on comprendra aisément que, si l'architecture du véhicule ne permet pas un montage et une transmission de couple moteur à l'avant du rail 8, l'orientation globale du dispositif suivant l'invention peut être inversée. L'organe d'entraínement est en conséquence transposé au niveau de l'extrémité arrière du rail 8 et l'organe de renvoi du câble est monté au niveau de l'extrémité avant de ce rail.Furthermore, it will be readily understood that, if the architecture of the vehicle does not allow mounting and transmission of engine torque to the front of the rail 8, the overall orientation of the device according to the invention can be reversed. The drive member is therefore transposed to the level from the rear end of the rail 8 and the cable return member is mounted on the level of the front end of this rail.

De plus, le dispositif suivant l'invention peut être monté indifféremment sur n'importe lequel des trois rails, en fonction de l'architecture du véhicule.In addition, the device according to the invention can be mounted indifferently on any of the three rails, depending on the architecture of the vehicle.

Par ailleurs, le profil en coupe du rail d'entraínement 8 est indifférent, dans la mesure où il permet le déplacement d'un chariot adapté à ce rail et le retour d'un brin de l'élément de traction souple 36, notamment dissimulé sous une paroi repliée, comme la paroi pliée 21.Furthermore, the sectional profile of the drive rail 8 is indifferent, insofar as it allows the movement of a trolley adapted to this rail and the return of a strand of the flexible traction element 36, in particular concealed under a folded wall, like the folded wall 21.

Enfin, une même porte coulissante peut être entraínée par plusieurs dispositifs synchronisés selon l'invention, chaque dispositif étant agencé sur un rail différent.Finally, the same sliding door can be driven by several synchronized devices according to the invention, each device being arranged on a different rail.
