Description

DISPOSITIF D'ARTICULATIONARTICULATION DEVICE
La présente invention concerne un dispositif d'articulation pour lier un élément mobile, notamment un organe d'un véhicule , à une structure fixe portante.The present invention relates to a hinge device for connecting a mobile element, in particular a member of a vehicle, to a fixed supporting structure.
Les éléments articulés , en particulier ceux d'un véhicule, tels que par exemple les portes , les roues , les éléments de la suspension, sont actuellement tous conçus pour pivoter autour d'un axe. Ce mode de fonctionnement présente un inconvénient majeur qui est de limiter le positionnement du centre de rotation en un point du véhicule, puisqu'il correspond à l'axe de pivotement qui dans ce cas est obligatoirement solidaire de la structure fixe de ce véhicule.The articulated elements, in particular those of a vehicle, such as for example the doors, the wheels, the elements of the suspension, are currently all designed to pivot around an axis. This operating mode has a major drawback which is to limit the positioning of the center of rotation at a point on the vehicle, since it corresponds to the pivot axis which in this case is necessarily integral with the fixed structure of this vehicle.
Pour des portes de véhicules , une telle limitation restreint l'angle d'ouverture et impose des contraintes techniques au créateur d'un modèle de carrosserie. Pour des suspensions , c'est de la position de l'axe d'articulation que dépend la délimitation d'une zone de confort où les mouvements du véhicule sont faibles et acceptables pour les passagers . Pour des raisons techniques , cet axe d'articulation est matérialisé sur le véhicule, ce qui interdit de le placer dans une position optimale.For vehicle doors, such a limitation restricts the opening angle and imposes technical constraints on the creator of a body model. For suspensions, it is on the position of the articulation axis that the delimitation of a comfort zone depends where the vehicle movements are weak and acceptable to the passengers. For technical reasons, this axis of articulation is materialized on the vehicle, which prevents it from being placed in an optimal position.
La présente invention se propose de résoudre ce problème et de pallier ces inconvénients en réalisant un dispositif qui permet de positionner cet axe fictivement en dehors du véhicule.The present invention proposes to solve this problem and to overcome these drawbacks by providing a device which makes it possible to position this axis fictitiously outside the vehicle.
Ce but est atteint par un dispositif tel que défini en préambule et caractérisé en ce qu'il comporte au moins un organe de guidage pour définir une trajectoire de déplacement dudit élément mobile, et au moins un organe suiveur agencé pour suivre la trajectoire définie par ledit organe de guidage , l'un de ces deux organes étant lié rigidement à ladite structure fixe portante.This object is achieved by a device as defined in the preamble and characterized in that it comprises at least one guide member for defining a path of movement of said movable element, and at least one follower member arranged to follow the path defined by said guide member, one of these two members being rigidly connected to said fixed supporting structure.
De façon avantageuse, ledit organe de guidage est solidaire de la structure fixe portante et ledit organe suiveur est solidaire de la structure fixe portante. De préférence ledit organe de guidage comporte un rail ayant un profil de guidage et ledit organe suiveur comporte des organes ayant un profil complémentaire audit profil de guidage pour permettre une liaison coulissante avec ledit rail.Advantageously, said guide member is secured to the fixed supporting structure and said follower member is secured to the fixed supporting structure. Preferably said guide member comprises a rail having a guide profile and said follower member comprises members having a profile complementary to said guide profile to allow a sliding connection with said rail.
Ledit organe suiveur peut être un chariot coulissant ou peut comportre des galets .Said follower member may be a sliding carriage or may include rollers.
Dans la forme de réalisation préférée, l'organe de guidage est couplé à un organe de direction du véhicule.In the preferred embodiment, the guide member is coupled to a vehicle steering member.
Ledit organe de guidage peut comporter une poche souple remplie d'un fluide hydraulique et au moins un cylindre agencé pour prendre appui sur ladite poche qui peut être connectée à des moyens d'alimentation en fluide hydraulique.Said guide member may include a flexible pocket filled with hydraulic fluid and at least one cylinder arranged to bear on said pocket which can be connected to means for supplying hydraulic fluid.
La présente invention et ses avantages apparaîtront mieux dans la description suivante d'exemples de réalisation et en référence aux dessins annexés dans lesquels :The present invention and its advantages will appear more clearly in the following description of exemplary embodiments and with reference to the appended drawings in which:
- la figure 1 est une vue de dessus d'un premier mode de réalisation du dispositif selon la présente invention;- Figure 1 is a top view of a first embodiment of the device according to the present invention;
- la figure 2 est une vue en coupe transversale selon la ligne I-I du dispositif de la figure 1 ;- Figure 2 is a cross-sectional view along line I-I of the device of Figure 1;
- la figure 3 est une vue de face d'un deuxième mode de réalisation d'un dispositif selon la présente invention;- Figure 3 is a front view of a second embodiment of a device according to the present invention;
- la figure 4 est une vue en coupe selon la ligne II— Il de la figure 3; et- Figure 4 is a sectional view along line II— II of Figure 3; and
- les figures 5 et 6 sont des vues partielles en coupe d'un troisième mode de réalisation du dispositif de la présente invention, dans deux positions différentes . Les figures 1 et 2 illustrent le dispositif d'articulation 10 de l'invention utilisé comme articulation de la roue directrice 11 d'un véhicule à deux roues comportant une structure fixe portante 12 partiellement représentée. Cette structure fixe portante peut être le châssis du véhicule, le bloc moteur ou un berceau portant ce bloc moteur. Le dispositif comprend un organe de guidage 13 lié par l'intermédiaire d'une fourche 1-4 et d'un axe 15, à la roue directrice 11 du véhicule et un organe suiveur 16 fixé rigidement à la structure fixe 12. L'organe de guidage 13 est formé d'un rail 17 ayant un profil définissant une gorge 18. Ce rail 17 présente une courbure donnée qui détermine la position de l'axe de pivotement 19 de la roue.- Figures 5 and 6 are partial sectional views of a third embodiment of the device of the present invention, in two different positions. Figures 1 and 2 illustrate the articulation device 10 of the invention used as articulation of the steering wheel 11 of a two-wheeled vehicle having a fixed supporting structure 12 partially shown. This fixed supporting structure can be the vehicle chassis, the engine block or a cradle carrying this engine block. The device comprises a guide member 13 connected via a fork 1-4 and an axle 15, to the steering wheel 11 of the vehicle and a follower member 16 rigidly fixed to the fixed structure 12. The member guide 13 is formed of a rail 17 having a profile defining a groove 18. This rail 17 has a given curvature which determines the position of the pivot axis 19 of the wheel.
L'organe suiveur 16 comporte un bloc en forme de boîtier parallélépipédique 20 qui contient deux paires de galets 21 rotatifs montés sur des axes traversants fixes 22. Le profil des galets 21 est complémentaire de celui du rail 17 de telle manière que le rail puisse coulisser entre les galets tout en étant maintenu par eux . Dans ce cas , c'est l'organe suiveur 16 qui est lié rigidement à la structure fixe 12 du véhicule et c'est le rail 17 constituant l'organe de guidageThe follower member 16 comprises a block in the form of a rectangular housing 20 which contains two pairs of rotating rollers 21 mounted on fixed through axes 22. The profile of the rollers 21 is complementary to that of the rail 17 so that the rail can slide between the rollers while being held by them. In this case, it is the follower member 16 which is rigidly linked to the fixed structure 12 of the vehicle and it is the rail 17 constituting the guide member
13 qui se déplace par rapport à l'organe suiveur 16. Le boîtier parallélépipédique 20 qui contient les galets 21 est monté sur la structure fixe 12 du véhicule au moyen d'un axe de liaison 23. Un amortisseur 24- est par ailleurs lié d'une part à ce boîtier 20 et d'autre part à la structure fixe 12 pour absorber les poussées verticales imposées à la roue.13 which moves relative to the follower member 16. The rectangular housing 20 which contains the rollers 21 is mounted on the fixed structure 12 of the vehicle by means of a connecting pin 23. A damper 24- is also linked to on the one hand to this housing 20 and on the other hand to the fixed structure 12 to absorb the vertical thrusts imposed on the wheel.
On constate que l'axe de pivotement 19 n'est pas directement matérialisé sur le véhicule, mais il est fictif et sa position est déterminée par la courbure du rail 17. De ce fait, il est possible de le déplacer selon les exigences techniques mises en évidence par le constructeur du véhicule. Si l'on désire un véhicule présentant des caractéristiques de stabilité importantes , on placera l'axe de pivotement relativement loin vers l'avant du véhicule. Ceci peut se faire en utilisant un rail 17 ayant un grand rayon de courbure. Si les caractéristiques de maniabilité du véhicule sont primordiales , le rail devra avoir un faible rayon de courbure afin que l'axe de pivotement 19 de la roue soit plus proche du véhicule.It is noted that the pivot axis 19 is not directly materialized on the vehicle, but it is fictitious and its position is determined by the curvature of the rail 17. Therefore, it is possible to move it according to the technical requirements put highlighted by the vehicle manufacturer. If a vehicle with important stability characteristics is desired, the pivot axis will be placed relatively far towards the front of the vehicle. This can be done using a rail 17 having a large radius of curvature. If the handling characteristics of the vehicle are essential, the rail must have a small radius of curvature so that the axis of pivoting 19 of the wheel is closer to the vehicle.
Les extrémités du rail 17 comportent deux butées 25 de fin de course destinées à limiter le déplacement angulaire de la roue 11. Une extrémité du rail 17 est liée à une biellette 26 reliée à un organe de direction (non représenté) tel qu'un guidon. Ainsi, lorsque l'on pivote le guidon, le rail 17 se déplace à travers le boîtier de l'organe suiveur 16 et fait pivoter la roue directrice 11 autour de l'axe de pivotement 19.The ends of the rail 17 comprise two end-of-travel stops 25 intended to limit the angular displacement of the wheel 11. One end of the rail 17 is linked to a connecting rod 26 connected to a steering member (not shown) such as a handlebar . Thus, when the handlebars are pivoted, the rail 17 moves through the casing of the follower member 16 and makes the steering wheel 11 pivot around the pivot axis 19.
Dans le mode de réalisation illustré , le fait que l'axe de pivotement 19 ne passe pas par le point de contact entre la roue directrice 11 et le sol implique que lorsque le pilote fait pivoter la roue , il génère un déplacement axial de cette roue. Ceci a pour effet de déplacer le plan médian de la roue par rapport à sa position normale et permet, notamment dans des moments critiques , de déplacer le point d'appui de la roue sur le sol par rapport à la projection sur ce dernier du centre de gravité du véhicule. La conséquence en est un agrandissement de la surface de sustentation du véhicule et une augmentation de sa stabilité due à un déplacement de la limite de stabilité.In the illustrated embodiment, the fact that the pivot axis 19 does not pass through the point of contact between the steering wheel 11 and the ground implies that when the driver rotates the wheel, it generates an axial displacement of this wheel . This has the effect of moving the median plane of the wheel with respect to its normal position and makes it possible, in particular at critical moments, to move the fulcrum of the wheel on the ground with respect to the projection onto the latter of the center vehicle gravity. The consequence is an enlargement of the lift surface of the vehicle and an increase in its stability due to a displacement of the stability limit.
Dans le mode de réalisation illustré par les figures 3 et 4 , le dispositif d'articulation 50 représenté permet le déplacement d'une porte 51 d'un véhicule 52 tel qu'une voiture, par rapport à la structure fixe portante 53 qui est la carrosserie de ce véhicule.In the embodiment illustrated in FIGS. 3 and 4, the articulation device 50 shown allows the movement of a door 51 of a vehicle 52 such as a car, relative to the fixed supporting structure 53 which is the bodywork of this vehicle.
Ce dispositif 50 est formé d'un organe de guidage 54 solidaire de la structure portante 53 et d'un organe suiveur 55 solidaire de la porte 51. L'organe de guidage 54 comprend par exemple une glissière 56 comportant un profil 57 en forme de T , fixée à la structure portante 53. L'organe suiveur 55 est formé d'un chariot coulissant 58 muni de quatre paliers à roulement 59 agencés pour être introduits dans le profil 57 de la glissière 56. La porte 51 du véhicule 52 est rendue solidaire du chariot coulissant 58. L'ouverture de cette porte 51 est assistée par un vérin 60 qui supporte la charge lorsqu'elle est en phase d'ouverture ou de fermeture. La forme et la courbure de la glissière 56 déterminent la position d'un axe de pivotement fictif 61 autour duquel pivote la porte. Cet axe peut être placé en dehors du véhicule, ce qui permet au créateur de modèles automobiles de s'affranchir de contraintes techniques limitatives . En outre, si la trajectoire choisie pour l'ouverture et la fermeture est complexe, l'axe de pivotement fictif est remplacé par plusieurs axes fictifs décalés les uns par rapport aux autres . Dans ce cas , le déplacement de la porte est équivalent à celui qui serait obtenu si l'axe d'articulation était mobile pendant ce déplacement.This device 50 is formed by a guide member 54 secured to the supporting structure 53 and a follower member 55 secured to the door 51. The guide member 54 comprises for example a slide 56 having a profile 57 in the form of T, fixed to the supporting structure 53. The follower member 55 is formed by a sliding carriage 58 provided with four rolling bearings 59 arranged to be introduced into the profile 57 of the slide 56. The door 51 of the vehicle 52 is rendered integral with the sliding carriage 58. The opening of this door 51 is assisted by a jack 60 which supports the load when it is in the opening or closing phase. The shape and curvature of the slide 56 determines the position of a fictitious pivot axis 61 around which the door pivots. This axis can be placed outside the vehicle, which allows the creator of automobile models to overcome limiting technical constraints. In addition, if the path chosen for opening and closing is complex, the fictitious pivot axis is replaced by several fictitious axes offset from one another. In this case, the movement of the door is equivalent to that which would be obtained if the hinge pin were mobile during this movement.
Une telle réalisation est impossible à adapter sur un véhicule automobile avec des moyens traditionnels , à savoir une articulation dont une partie est liée à l'organe mobile et l'autre à la structure portante .Such an embodiment is impossible to adapt to a motor vehicle with traditional means, namely a joint, part of which is linked to the movable member and the other to the bearing structure.
Un troisième mode de réalisation de la présente invention est illustré par les figures 5 et 6. Cette réalisation est adaptée à la suspension d'un wagon 100 de train ou de tout autre véhicule sur rail. Le wagon 100 comporte une structure fixe portante 101 dans laquelle est montée une cabine pivotante 102 reliée à cette structure par l'intermédiaire d'un dispositif d'articulation 103 formé d'un organe de guidage 104 solidaire de la structure portante 101 , et d'un organe suiveur 105 solidaire de la cabine 102.A third embodiment of the present invention is illustrated in FIGS. 5 and 6. This embodiment is suitable for the suspension of a train wagon 100 or of any other vehicle on rail. The wagon 100 comprises a fixed carrying structure 101 in which is mounted a pivoting cabin 102 connected to this structure via an articulation device 103 formed by a guide member 104 integral with the carrying structure 101, and d 'A follower member 105 secured to the cabin 102.
L'organe de guidage 104 comporte une rampe 106 arrondie, disposée au bas de la structure portante 101. Cet organe de guidage 104 comporte également une poche 107 remplie d'un fluide et limitée par deux butées longitudinales 108. L'organe suiveur 105 comporte deux cylindres longitudinaux 109 montés de part et d'autre de la poche 107 de manière à se déplacer le long de cette poche.The guide member 104 comprises a rounded ramp 106, disposed at the bottom of the supporting structure 101. This guide member 104 also includes a pocket 107 filled with a fluid and limited by two longitudinal stops 108. The follower member 105 comprises two longitudinal cylinders 109 mounted on either side of the pocket 107 so as to move along this pocket.
Lorsque la structure portante 101 du wagon 100 s'incline, la cabine pivotante 102 glisse sur la rampe 106 et l'organe suiveur 105 se déplace le long de la poche 107 de façon que la cabine 102 compense au moins partiellement l'inclinaison de la structure portante 101. La forme et la courbure de la rampe 106 définit la position d'un axe de pivotement 110 autour duquel pivote cette cabine. Du fait que la courbure peut être modifiée , l'axe de pivotement 110 de la cabine pivotante peut être placé n'importe où aussi bien à l'intérieur qu'à l'extérieur du wagon. Cette liberté permet de positionner l'axe de pivotement en tenant compte uniquement du confort des passagers sans avoir d'impératifs techniques à respecter.When the carrying structure 101 of the wagon 100 tilts, the pivoting cabin 102 slides on the ramp 106 and the follower member 105 moves along the pocket 107 so that the cabin 102 at least partially compensates for the inclination of the bearing structure 101. The shape and curvature of the ramp 106 defines the position of a pivot axis 110 around which this cabin pivots. Because the curvature can be changed, the pivot axis 110 of the pivoting cabin can be placed anywhere both inside and outside the wagon. This freedom makes it possible to position the pivot axis taking into account only the comfort of the passengers without having to meet technical requirements.
La poche 107 peut être associée à des moyens d'alimentation en fluide hydraulique, ce qui permet de gérer l'inclinaison de la cabine. La poche peut être assimilée à un vérin à double effet. Les deux cylindres 109 définissent un étranglement qui délimite deux chambresThe pocket 107 can be associated with means for supplying hydraulic fluid, which makes it possible to manage the inclination of the cabin. The pocket can be compared to a double-acting cylinder. The two cylinders 109 define a constriction which delimits two chambers
111. L'alimentation de l'une des chambres au détriment de l'autre génère un déplacement de la cabine 102. La gestion de ce déplacement peut être faite par une unité centrale de commande des moyens d'alimentation 112 en fluide hydraulique, qui reçoit des informations extérieures de capteurs appropriés .111. The supply of one of the chambers to the detriment of the other generates a displacement of the cabin 102. The management of this displacement can be made by a central control unit for the means 112 for supplying hydraulic fluid, which receives external information from appropriate sensors.
Les trois modes de réalisation décrits montrent que l'utilisation d'un tel dispositif d'articulation offre une grande liberté au concepteur et au constructeur de véhicules . La possibilité de placer l'axe de pivotement à volonté sur et à l'intérieur du véhicule permet d'améliorer la maniabilité, la sécurité et le confort de ces véhicules . Elle permet au créateur de s'affranchir des contraintes techniques et de donner libre cours son imagination. The three embodiments described show that the use of such an articulation device offers great freedom to the designer and the vehicle manufacturer. The possibility of placing the pivot axis at will on and inside the vehicle improves the handling, safety and comfort of these vehicles. It allows the creator to overcome technical constraints and give free rein to his imagination.
