Abstract

The assembly consists of a roller (30) connected by a support (22) to the sliding door (8) and moving in a guide rail (18) fixed to the vehicle body (4). The roller has two rolling surfaces (40, 46) on either side of a plane of symmetry (M) lying perpendicular to its axis (X-X), and lines (N1, N2) perpendicular to the working surfaces have axial components (C1, C2) that are parallel to the roller's axis and act in opposite directions.

Description

La présente invention concerne un ensemble de support et de guidage tel que décrit par le préambule de la revendication 1.The present invention relates to a support and guide assembly as described by the preamble of claim 1.

Un tel ensemble est connu de US-A-6,286,261.Such an assembly is known from US-A-6,286,261.

Elle s'applique notamment aux portes latérales coulissantes des véhicules de loisir ou utilitaires.It applies in particular to the sliding side doors of leisure or utility vehicles.

On connaît des portes coulissantes des véhicules automobiles comprenant un ensemble de support et de guidage formé par un galet porteur et par deux galets de guidage. Le galet porteur est monté mobile en rotation autour d'un axe horizontal, tandis que les deux galets de guidage sont mobiles en rotation autour de deux axes parallèles verticaux.Motor vehicle sliding doors are known comprising a support and guide assembly formed by a carrier roller and by two guide rollers. The carrier roller is rotatably mounted about a horizontal axis, while the two guide rollers are rotatable about two vertical parallel axes.

A l'état monté, l'ensemble est disposé dans un rail, qui est constitué d'un profilé creux de section rectangulaire, de façon à pouvoir coulisser le long de ce rail.In the assembled state, the assembly is arranged in a rail, which consists of a hollow section of rectangular section, so as to slide along the rail.

Afin de permettre un déplacement de l'ensemble de support et de guidage, la distance entre les deux parois du profilé associées à un galet de guidage est légèrement supérieure au diamètre de ce galet.In order to allow movement of the support and guide assembly, the distance between the two walls of the profile associated with a guide roller is slightly greater than the diameter of this roller.

En conséquence, pendant le coulissement de la porte entre ses positions ouverte et fermée, les galets de guidage ne sont pas toujours en contact avec la paroi du profilé et s'appliquent de façon alternée contre les deux parois, ce qui génère des bruits désagréables pour les occupants du véhicule.Consequently, during the sliding of the door between its open and closed positions, the guide rollers are not always in contact with the wall of the profile and are applied alternately against the two walls, which generates unpleasant noises for the occupants of the vehicle.

Par ailleurs, les galets de support sont habituellement fabriqués par forgeage. Le plan de séparation du moule coupe la surface de roulement. En conséquence, le galet forgé doit être soigneusement ébarbé afin d'éviter des endommagements de la surface de roulement du rail de guidage. Cette étape d'ébarbement est coûteux.In addition, the support rollers are usually made by forging. The separation plane of the mold cuts the running surface. As a result, the forged roller must be carefully deburred to avoid damage to the running surface of the guide rail. This debarking step is expensive.

En outre, de tels ensembles de support et de guidage comprennent de nombreuses pièces, ce qui rend leur fabrication et leur assemblage onéreux.In addition, such support and guide assemblies include many parts, which makes their manufacture and assembly expensive.

La présente invention a pour but de pallier ces inconvénients et de proposer un ensemble de support et de guidage qui génère peu de bruits pendant le fonctionnement, et qui soit facile et économique à fabriquer, tout en assurant un guidage efficace de la porte latérale lors de son coulissement.The present invention aims to overcome these disadvantages and to provide a support and guide assembly that generates little noise during operation, and is easy and economical to manufacture, while ensuring effective guidance of the side door when its sliding.

A cet effet, l'invention a pour objet un ensemble du type précité, caractérisé par la partie caractérisante de la revendication 1.For this purpose, the subject of the invention is an assembly of the aforementioned type, characterized by the characterizing part of claim 1.

Selon d'autres modes de réalisation, l'invention peut comporter l'une ou plusieurs des caractéristiques décrites dans les sous-revendications 2 à 21.According to other embodiments, the invention may include one or more of the features described in subclaims 2 to 21.

L'invention a en outre pour objet une porte coulissante pour véhicule automobile comprenant les caractéristiques des revendications 22 ou 23.The invention further relates to a sliding door for a motor vehicle comprising the features of claims 22 or 23.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • la Figure 1 est une vue schématique de côté d'un véhicule comprenant une porte coulissante selon l'invention ;
  • la Figure 2 est une vue en coupe suivant la ligne II-II de la Figure 1 d'un ensemble de support et de guidage selon un premier mode de réalisation de l'invention ;
  • la Figure 3 est une vue en perspective d'un ensemble de support et de guidage selon un second mode de réalisation de l'invention ; et
  • la Figure 4 est une vue en perspective du module de galet de l'ensemble de la Figure 3.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
  • Figure 1 is a schematic side view of a vehicle comprising a sliding door according to the invention;
  • Figure 2 is a sectional view along line II-II of Figure 1 of a support and guide assembly according to a first embodiment of the invention;
  • Figure 3 is a perspective view of a support and guide assembly according to a second embodiment of the invention; and
  • Figure 4 is a perspective view of the roller module of the assembly of Figure 3.

Sur la Figure 1 est représenté un véhicule automobile par exemple du type « monospace» ou du type utilitaire désigné par la référence générale 2.In Figure 1 is shown a motor vehicle for example of the type "minivan" or utility type designated by the general reference 2.

Dans ce qui suit, les expressions « avant », « arrière » et « latéralement » seront utilisées par rapport à l'orientation habituelle du véhicule.In what follows, the terms "before", "back" and "laterally" will be used in relation to the usual orientation of the vehicle.

Le véhicule 2 comporte une carrosserie 4 délimitant une ouverture latérale 6, qui permet l'accès à l'intérieur de ce véhicule 2, et notamment à la partie arrière de l'habitacle.The vehicle 2 has a body 4 defining a side opening 6, which allows access to the interior of the vehicle 2, and in particular to the rear part of the passenger compartment.

Une porte latérale 8 coulissante est montée sur le côté latéral de la carrosserie 4. Cette porte 8 est mobile en translation entre une position avant de fermeture de l'ouverture latérale 6 (Figure 1) et une position arrière de libération de cette ouverture latérale (non-représentée).A sliding side door 8 is mounted on the lateral side of the bodywork 4. This door 8 is movable in translation between a front position of closure of the lateral opening 6 (FIG. 1) and a rear position of release of this lateral opening (FIG. not shown).

A cet effet, la porte 8 est reliée à la carrosserie au moyen de trois ensembles de coulisse, dont un ensemble de coulisse supérieur 10 qui est constitué d'un galet porteur, connu en soi et deux ensembles de coulisse respectivement médian 12 et inférieur 14 de support et de guidage. Les ensembles de coulisse 10, 12 et 14 sont interposés entre la carrosserie 4 et la porte latérale 8.For this purpose, the door 8 is connected to the body by means of three slide assemblies, including an upper slide assembly 10 which consists of a carrier roller, known per se and two sets of slides respectively median 12 and lower 14 support and guidance. The slide assemblies 10, 12 and 14 are interposed between the bodywork 4 and the side door 8.

Les ensembles 12, 14 de support et de guidage sont adaptés pour, d'une part, supporter le poids de la porte 8 et, d'autre part, guider latéralement la porte lors de son déplacement. Dans la suite l'ensemble médian 12 de support et de guidage sera décrit, l'ensemble inférieur 14 étant identique.The support and guide assemblies 12, 14 are adapted to, on the one hand, support the weight of the door 8 and, on the other hand, laterally guide the door during its movement. In the following the median assembly 12 of support and guidance will be described, the lower assembly 14 being identical.

L'ensemble 12 de support et de guidage comprend un module de galet 16 et un rail 18 de support et de guidage dans lequel le module de galet 16 est reçu, comme ceci ressort de la Figure 2.The support and guide assembly 12 comprises a roller module 16 and a support and guide rail 18 in which the roller module 16 is received, as is apparent from FIG. 2.

Le module de galet 16 comporte une broche 20 s'étendant suivant un premier axe X-X qui est disposé perpendiculairement au plan général de la porte latérale 8. La broche 20 a une extrémité filetée 22. Le module de galet 16 est fixé au moyen d'un écrou 24 et d'un contre-écrou 26 au corps de la porte 8. La broche 20 s'étend, à l'état monté de la porte 8, horizontalement.The roller module 16 comprises a spindle 20 extending along a first axis XX which is arranged perpendicular to the general plane of the side door 8. The spindle 20 has a threaded end 22. The roller module 16 is fixed by means of a nut 24 and a locknut 26 to the body of the door 8. The spindle 20 extends, in the mounted state of the door 8, horizontally.

La broche 20 comporte, à sa partie distale de la porte 8, une collerette formant butée centrale 28 solidaire de la broche 20 et définissant un plan de symétrie M-M.The pin 20 has, at its distal portion of the door 8, a flange forming a central abutment 28 secured to the pin 20 and defining a plane of symmetry M-M.

Le module de galet 16 comprend en outre un corps de roulement 30 constitué de deux galets identiques respectivement 32, 34, montés sur la broche 20 de part et d'autre du plan médian M-M, c'est-à-dire de la butée centrale 28. Ces galets 32, 34 sont mobiles en rotation et en translation sur la broche 20.The roller module 16 further comprises a rolling body 30 consisting of two identical rollers 32, 34 respectively, mounted on the spindle 20 on either side of the median plane MM, that is to say of the central abutment 28. These rollers 32, 34 are movable in rotation and in translation on the spindle 20.

Le galet 32 comporte deux parois latérales planes et opposées, respectivement 36 et 38, l'une 36 en regard de la carrosserie 4 et l'autre 38 en regard de la butée centrale 28, reliées entre elles par une portion courbe 40 formant une surface de roulement. Cette surface de roulement 40 présente de préférence une forme bombée convexe d'une portion de sphère. La surface de roulement 40 a une normale N1, qui comprend une composante axiale C1 s'étendant parallèlement à l'axe X-X.The roller 32 comprises two opposite and flat side walls, respectively 36 and 38, one 36 facing the bodywork 4 and the other 38 facing the central stop 28, interconnected by a curved portion 40 forming a surface rolling. This running surface 40 preferably has a convex convex shape of a sphere portion. The running surface 40 has a normal N 1 , which comprises an axial component C 1 extending parallel to the axis XX.

De même, le galet 34 comporte deux parois latérales planes et opposées, respectivement 42 et 44, l'une 42 en regard de la porte latérale 8 et l'autre 44 en regard de la butée centrale 28, reliées entre elles par une portion courbe 46 formant une surface de roulement. Cette surface de roulement 46 présente de préférence une forme bombée convexe d'une portion de sphère. La surface de roulement 46 a une normale N2 qui comprend une composante axiale C2 s'étendant parallèlement à l'axe X-X.Similarly, the roller 34 has two flat and opposite side walls, respectively 42 and 44, one 42 facing the side door 8 and the other 44 opposite the central abutment 28, interconnected by a curved portion 46 forming a running surface. This rolling surface 46 preferably has a convex convex shape of a sphere portion. The rolling surface 46 has a normal N 2 which comprises an axial component C 2 extending parallel to the axis XX.

En d'autres termes, la surface de roulement 40, 46 du galet le plus près de chaque extrémité de la broche 20 comporte une composante axiale C1, C2 qui est dirigée vers cette extrémité de la broche 20.In other words, the rolling surface 40, 46 of the roller closest to each end of the spindle 20 has an axial component C 1 , C 2 which is directed towards this end of the pin 20.

Un organe élastique formant ressort, en l'occurrence une rondelle Belleville respectivement 48, 50, est interposé entre chaque galet 32, 34 et la butée centrale 28. Les deux rondelles Belleville 48, 50 sollicitent chacun des galets 32, 34 dans le sens axial de la surface de roulement 40, 46 du galet 32, 34 respectif.An elastic spring member, in this case a Belleville washer 48, 50 respectively, is interposed between each roller 32, 34 and the central stop 28. The two Belleville washers 48, 50 each urge the rollers 32, 34 in the axial direction of the running surface 40, 46 of the roller 32, 34 respectively.

Ainsi, la rondelle Belleville 48 est interposée entre la paroi latérale 38 du galet 32 et la butée centrale 28 de façon à exercer une poussée sur le galet 32 dans un sens dirigé vers la carrosserie 4 et la rondelle Belleville 50 est interposée entre la paroi latérale 44 du galet 34 et la butée centrale 28 afin d'exercer une poussée sur le galet 34 dans un sens dirigé vers la porte latérale 8. De ce fait, les galets 32, 34 sont sollicités dans deux sens axiaux opposés de façon à les écarter l'un de l'autre.Thus, the Belleville washer 48 is interposed between the side wall 38 of the roller 32 and the central stop 28 so as to exert a thrust on the roller 32 in a direction directed towards the bodywork 4 and the Belleville washer 50 is interposed between the side wall 44 of the roller 34 and the central stop 28 to exert a thrust on the roller 34 in a direction directed towards the side door 8. As a result, the rollers 32, 34 are biased in two opposite axial directions so as to remove them one of the other.

La broche 20 comporte en outre deux rainures 52, 54 annulaires ménagées à distance de part et d'autre de la butée centrale 28.The pin 20 further comprises two annular grooves 52, 54 arranged remotely on either side of the central stop 28.

Un jonc fendu 56, 58 est encliqueté dans chacune des rainures 52, 54 de chaque côté des galets opposé à la butée centrale 28. Les joncs fendus 56, 58 forment des butées latérales et limitent le déplacement axial des galets 32, 34 lorsqu'ils ne sont pas sollicités par le poids de la porte 8.A split ring 56, 58 is snapped into each of the grooves 52, 54 on each side of the rollers opposite the central stop 28. The split rings 56, 58 form lateral stops and limit the axial displacement of the rollers 32, 34 when are not solicited by the weight of the door 8.

La partie du module de galet 16 qui se trouve à l'intérieur du rail 18 est symétrique par rapport au plan M-M.The part of the roller module 16 which is inside the rail 18 is symmetrical with respect to the plane M-M.

Le rail 18 de support et de guidage est constitué d'un profilé 60, par exemple en métal extrudé, fixé sur le côté latéral du châssis 4 du véhicule 2 par des moyens classiques de fixation (non représentés). Ce profilé 60 présente une section transversale sensiblement de forme générale hexagonale. La section transversale est identique sur la longueur du rail 18 et est symétrique par rapport à un plan central C-C qui s'étend horizontalement, donc parallèlement à l'axe X-X, à l'état monté du rail 18.The rail 18 support and guide consists of a profile 60, for example extruded metal, fixed on the lateral side of the frame 4 of the vehicle 2 by conventional means of attachment (not shown). This profile 60 has a cross section substantially of shape general hexagonal. The cross section is identical over the length of the rail 18 and is symmetrical with respect to a central plane CC which extends horizontally, therefore parallel to the axis XX, in the mounted state of the rail 18.

Le profilé 60 comporte une première paire 62 de pistes 64, 66 rectilignes et en forme de V ouvert vers les galets 32, 34. Les pistes 64, 66 sont dirigées l'une vers l'autre. Sur la piste 64, le galet 32 prend appui tandis que le galet 34 prend appui sur la piste 66.The profile 60 comprises a first pair 62 of tracks 64, 66 rectilinear and V-shaped open towards the rollers 32, 34. The tracks 64, 66 are directed towards each other. On the track 64, the roller 32 is supported while the roller 34 is supported on the track 66.

Ainsi, la première paire 62 de pistes a une forme complémentaire aux surfaces de roulement 40, 46 des galets.Thus, the first pair 62 of tracks has a shape complementary to the rolling surfaces 40, 46 of the rollers.

Du côté opposé de la première paire 62 de pistes, le profilé 60 comporte une seconde paire 68 de pistes 70, 72, identique à la première paire 62.On the opposite side of the first pair of tracks 62, the profile 60 includes a second pair 68 of tracks 70, 72, identical to the first pair 62.

Les deux paires 62, 68 de pistes sont reliées par une branche centrale 74 de liaison qui est fixée au châssis 4. Du côté opposé de la branche de liaison 74 le profilé 60 comporte deux rebords 76, 78 qui délimitent un passage 80 pour la broche 20.The two pairs 62, 68 of tracks are connected by a central connecting branch 74 which is fixed to the frame 4. On the opposite side of the connecting branch 74 the profile 60 comprises two flanges 76, 78 which delimit a passage 80 for the spindle 20.

La distance d entre la butée centrale 28 et chacun des joncs fendus 56, 58 est choisie de telle sorte que, lorsque les galets 32, 34 butent contre les joncs 56, 58, un contact simultané des galets 32, 34 avec les deux paires de pistes 62, 68 du rail soit empêché.The distance d between the central stop 28 and each of the split rings 56, 58 is chosen such that, when the rollers 32, 34 abut against the rods 56, 58, simultaneous contact of the rollers 32, 34 with the two pairs of tracks 62, 68 of the rail is prevented.

Grâce au fait que les deux paires 62, 68 de pistes sont symétriques par rapport au plan M-M, le rail 18 et le module de galet 16 peuvent être utilisés pour une porte gauche 8 (telle que représentée) ou pour une porte droite. Dans ce dernier cas, le rail 18 et le module de galet 16 sont tournés de 180° par rapport à la Figure 2, de telle sorte que les galets 32, 34 prennent appui sur la seconde paire 68 de pistes.Due to the fact that the two pairs 62, 68 of tracks are symmetrical with respect to the plane M-M, the rail 18 and the roller module 16 can be used for a left door 8 (as shown) or for a right door. In the latter case, the rail 18 and the roller module 16 are turned 180 ° relative to Figure 2, so that the rollers 32, 34 are supported on the second pair 68 of tracks.

L'ensemble de support et de guidage est assemblé et monté de la façon suivante :The support and guide assembly is assembled and mounted as follows:

Les rondelles Belleville 48, 50 ainsi que les galets 32, 34 sont enfichés sur la broche 20 de part et d'autre de la butée centrale 28.The Belleville washers 48, 50 and the rollers 32, 34 are plugged onto the pin 20 on either side of the central stop 28.

Puis les joncs fendus 56, 58 sont encliquetés dans les rainures 52, 54.Then the snap rings 56, 58 are snapped into the grooves 52, 54.

Enfin, le module de galet 16 est vissé sur la porte 8 et fixé par l'écrou 24 et le contre-écrou 26. Un premier module de galet 16 est fixé à la partie médiane arrière de la porte 8, tandis qu'un second module, identique au premier, est fixé à la partie basse avant de la porte 8. Un module porteur 10 connu en soi est fixé à l'emplacement correspondant haut avant de la porte 8.Finally, the roller module 16 is screwed on the door 8 and fixed by the nut 24 and the locknut 26. A first roller module 16 is fixed to the rear middle part of the door 8, while a second module, identical to the first, is fixed to the lower front part of the door 8. A carrier module 10 known per se is fixed at the corresponding location high front of the door 8.

Les rails 18 de support et de guidage sont fixés sur la carrosserie 4 du véhicule, par exemple par vissage. Ensuite, chaque module de galet 16 est enfilé dans le rail 18 correspondant. Lorsque la porte 8, sous l'action de son poids, sollicite les galets 32, 34 contre les pistes 64, 66 de la première paire 62 de pistes, la force radiale agissant sur les galets 32, 34 est transformée en une composante radiale et une composante axiale qui sollicite chaque galet 32, 34 à l'encontre de l'effort de la rondelle Belleville 48, 50 associée.The rails 18 for support and guidance are fixed to the bodywork 4 of the vehicle, for example by screwing. Then, each roller module 16 is threaded into the corresponding rail 18. When the door 8, under the action of its weight, biases the rollers 32, 34 against the tracks 64, 66 of the first pair 62 of tracks, the radial force acting on the rollers 32, 34 is transformed into a radial component and an axial component that urges each roller 32, 34 against the force of the washer Belleville 48, 50 associated.

En conséquence, chacun des galets 32, 34 s'applique à chaque instant contre la piste 64, 66 correspondante pendant le coulissement, ce qui évite des bruits de contact entre les galets 32, 34 et les pistes 64, 66.Consequently, each of the rollers 32, 34 applies at each instant against the corresponding track 64, 66 during sliding, which avoids contact noises between the rollers 32, 34 and the tracks 64, 66.

Par ailleurs, des tolérances de fabrication concernant l'écart entre les deux ensembles 12, 14 de support et de guidage sont compensées.Moreover, manufacturing tolerances concerning the distance between the two support and guide assemblies 12, 14 are compensated.

Le fait que les deux galets 32, 34 soient identiques conduit à un faible coût de fabrication.The fact that the two rollers 32, 34 are identical leads to a low manufacturing cost.

Les deux galets 32, 34 d'un module de galet 16 sont disposés suivant un même axe X-X. En conséquence, les manipulations lors de l'assemblage sont simples.The two rollers 32, 34 of a roller module 16 are arranged along the same axis XX. As a result, the manipulations during assembly are simple.

Sur la Figure 3, est représenté, vu en perspective, un ensemble de support et de guidage selon un second mode de réalisation de l'invention.In Figure 3, is shown, in perspective, a support assembly and guide according to a second embodiment of the invention.

Dans ce qui suit, uniquement les différences par rapport au premier mode de réalisation seront décrites. Les éléments analogues portent les mêmes références.In what follows, only the differences with respect to the first embodiment will be described. Similar elements bear the same references.

L'ensemble de support et de guidage 12 comprend un rail de support et de guidage 18 identique à celui du premier mode de réalisation. En outre, l'ensemble de support et de guidage 12 comporte un module de galet 16.The support and guide assembly 12 comprises a support and guide rail 18 identical to that of the first embodiment. In addition, the support and guide assembly 12 includes a roller module 16.

Le module de galet 16 comprend un support 100, qui comprend un corps de base formé d'une bride 102 sensiblement en forme de C. La bride 102 est formée d'une seule pièce par pliage d'une tôle. Elle comporte deux branches libres parallèles 104, une branche centrale 106 et une branche supplémentaire 108.The roller unit 16 comprises a support 100, which comprises a base body formed of a substantially C-shaped flange 102. The flange 102 is formed in one piece by folding a sheet. It comprises two parallel free branches 104, a central branch 106 and an additional branch 108.

La branche supplémentaire 108 s'étend à partir de la branche centrale 106 parallèlement à l'axe X-X. Elle s'étend également parallèlement aux branches libres 104 et du côté de la branche centrale 106, opposé aux branches libres 104.The additional branch 108 extends from the central branch 106 parallel to the X-X axis. It also extends parallel to the free branches 104 and the side of the central branch 106, opposite to the free branches 104.

Le support 100 comprend en outre une douille d'articulation 110, interposée entre les branches libres 104 de la bride 102. La douille d'articulation 110 s'étend suivant un deuxième axe Y-Y. Cet axe Y-Y s'étend perpendiculairement par rapport à l'axe X-X, et à l'état monté, généralement verticalement. Le support 100 est articulé par l'intermédiaire de la douille 110 à un élément de structure du véhicule automobile, en l'occurrence à la porte 8.The support 100 further comprises a hinge sleeve 110 interposed between the free branches 104 of the flange 102. The hinge sleeve 110 extends along a second axis Y-Y. This Y-Y axis extends perpendicular to the X-X axis, and in the mounted state, generally vertically. The support 100 is articulated via the bushing 110 to a structural element of the motor vehicle, in this case to the door 8.

Le module de galet 16 comprend en outre un ressort hélicoïdal 112 enroulé autour de la douille d'articulation 110. Ce ressort 112 prend appui d'une part sur le support 100, et d'autre part sur la porte 8, et sollicite le support 100 vers une position, dans laquelle le premier axe X-X s'étend sensiblement perpendiculairement au plan de la porte 8.The roller module 16 further comprises a helical spring 112 wound around the hinge sleeve 110. This spring 112 is supported on the one hand on the support 100, and on the other hand on the door 8, and urges the support 100 to a position, in which the first axis XX extends substantially perpendicularly to the plane of the door 8.

La broche 20 du module de galet 16 est solidaire de la branche centrale 106 du support.The spindle 20 of the roller module 16 is integral with the central branch 106 of the support.

Le module de galet 16 comprend en outre un corps de roulement 30 formé d'un seul galet 120 qui est monté en rotation sur la broche 20 du module.The roller module 16 further comprises a rolling body 30 formed of a single roller 120 which is rotatably mounted on the pin 20 of the module.

Le galet 120 comprend deux parties 122, 124 solidaires en rotation autour de l'axe X-X, dont chacune porte l'une des surfaces de roulement 40, 46. Les surfaces de roulement 40, 46 ont une forme tronconique, et s'étendent de part et d'autre du plan de symétrie M-M, à l'écart de ce plan M-M. Les surfaces de roulement 40, 46 du galet 120 ont donc également des normales N1, N2 dont les composantes axiales C1, C2 s'étendent dans des sens opposés.The roller 120 comprises two parts 122, 124 integral in rotation about the axis XX, each bearing one of the rolling surfaces 40, 46. The rolling surfaces 40, 46 have a frustoconical shape, and extend from on both sides of the plane of symmetry MM, away from this plane MM. The rolling surfaces 40, 46 of the roller 120 therefore also have normals N 1 , N 2 whose axial components C 1 , C 2 extend in opposite directions.

Les surfaces de roulement 40, 46 sont reliées par une surface cylindrique 126.The running surfaces 40, 46 are connected by a cylindrical surface 126.

Le galet 120 est fabriqué d'un seul tenant, et de préférence d'une seule pièce. En l'occurrence, le galet est fabriqué par forgeage.The roller 120 is made in one piece, and preferably in one piece. In this case, the roller is manufactured by forging.

Sur la Figure 4 est indiquée la ligne de séparation L du moule de forgeage. Cette ligne L s'étend dans le plan de symétrie M-M, et en conséquence, complètement en dehors des surfaces de roulement 40, 46 de sorte que le galet 120 n'a besoin d'être ébarbé que grossièrement.In Figure 4 is indicated the separation line L of the forging mold. This line L extends in the plane of symmetry MM, and accordingly, completely outside the running surfaces 40, 46 so that the roller 120 needs to be trimmed only roughly.

Le module de galet 46 comprend en outre un seul galet de guidage latéral 130. Le galet de guidage latéral 130 est monté sur un ergot 132 disposé sur la branche supplémentaire 108 du support 100. Le galet de guidage latéral 130 est mobile en rotation autour d'un axe Z-Z qui s'étend perpendiculairement à l'axe X-X, et parallèlement à l'axe Y-Y.The roller module 46 further comprises a single lateral guide roller 130. The lateral guide roller 130 is mounted on a lug 132 disposed on the additional branch 108 of the support 100. The lateral guide roller 130 is rotatable around the edge an axis ZZ extending perpendicularly to the axis XX, and parallel to the axis YY.

En variante encore, le module de galet comporte un support de broches qui est articulé par rapport à la porte autour d'un axe s'étendant verticalement à l'état monté. Deux broches 20 parallèles, comportant chacune une paire de galets 32, 34 et une paire de rondelles Belleville 48, 50 tels que décrits ci-dessus, sont reliés à ce support, l'un derrière l'autre dans la direction du rail 18.In another variant, the roller module comprises a pin holder which is articulated with respect to the door around an axis extending vertically in the mounted state. Two parallel pins 20, each having a pair of rollers 32, 34 and a pair of Belleville washers 48, 50 as described above, are connected to this support, one behind the other in the direction of the rail 18.

De manière générale, les surfaces de roulement 40, 46 sont inclinées au premier axe X-X en tout point d'un angle supérieur à 5°, de préférence d'un angle supérieur à 10°.In general, the running surfaces 40, 46 are inclined at the first axis X-X at any point by an angle greater than 5 °, preferably by an angle greater than 10 °.

En variante encore, les pistes 64, 66 ou 70, 72, des paires de pistes 62, 68 sont reliées l'une à l'autre par une partie plane s'étendant perpendiculairement au plan M-M et parallèlement au plan C-C.In another variant, the tracks 64, 66 or 70, 72 pairs of tracks 62, 68 are connected to each other by a flat portion extending perpendicular to the plane M-M and parallel to the plane C-C.

Le rail 18 a en conséquence une section transversale octogonale.The rail 18 therefore has an octagonal cross section.

Ainsi, les deux galets 32, 34 peuvent être écartés l'un de l'autre d'une distance importante, tandis que le rail 18 garde un encombrement faible dans une direction perpendiculaire au plan médian C-C.Thus, the two rollers 32, 34 can be spaced from each other by a significant distance, while the rail 18 keeps a small footprint in a direction perpendicular to the median plane C-C.
