Description

La présente invention a pour objet un dispositif tendeur de câble unidirectionnel pour lève-vitre de véhicule automobile.The present invention relates to a unidirectional cable tensioning device for a window regulator in a motor vehicle.

Ce dispositif est du type comprenant un carter dans lequel sont logés un treuil d'entraînement du câble susceptible d'être entraîné par un moteur, ou manuellement, ainsi que deux embouts recevant chacun une extrémité d'une gaine contenant le câble, ces embouts étant chacun soumis à la sollicitation élastique d'un ressort de compression monté dans le, carter coaxialement au câble.This device is of the type comprising a casing in which are housed a cable drive winch capable of being driven by a motor, or manually, as well as two end pieces each receiving one end of a sheath containing the cable, these end pieces being each subject to the elastic stress of a compression spring mounted in the casing coaxially with the cable.

Pour qu'un tel. dispositif fonctionne correctement, il faut que le câble (câble Bowden) soit tendu en permanence, afin d'éviter des risques de déraillement ainsi que l'apparition d'un jeu à la manivelle et à la vitre. Or, on observe en pratique, en cours de fonctionnement de ces lève-vitres, un allongement sensible du câble, qui peut atteindre jusqu'à 35 mm pour les lève-vitres électriques.So that such. device is working correctly, the cable (Bowden cable) must be permanently tensioned, in order to avoid the risk of derailment as well as the appearance of a play in the crank and the window. However, in practice, during operation of these window regulators, a substantial elongation of the cable is observed, which can reach up to 35 mm for electric window regulators.

Pour compenser cet allongement, on utilise en général des ressorts de compression montés entre un embout de gaine et son support, un ressort assurant la tension dans un sens et le second assurant la tension du câble dans l'autre sens. Ce montage règle le problème de la tension du câble, mais non celui du jeu, qui devient alors élastique. Ceci peut être aisément constaté en appuyant sur la vitre, qu'on peut en effet faire ainsi descendre de la valeur dont on peut comprimer le ressort (15 à 20 mm par exemple).To compensate for this elongation, compression springs are generally used mounted between a sheath end piece and its support, one spring ensuring tension in one direction and the second ensuring tension in the cable in the other direction. This assembly solves the problem of the tension of the cable, but not that of the play, which then becomes elastic. This can be easily seen by pressing the window, which can in fact lower the value by which the spring can be compressed (15 to 20 mm for example).

L'invention a pour but d'éliminer cet inconvénient en réalisant une liaison rigide dans le sens de la compression de la gaine, entre l'embout et son support, et qui permette d'assurer la tension du câble.The invention aims to eliminate this drawback by providing a rigid connection in the direction of compression of the sheath, between the end piece and its support, and which makes it possible to ensure the tension of the cable.

Suivant l'invention, chaque embout de gaine est pourvu sur une de ses faces, d'une denture s'étendant parallèlement au câble et qui engrène avec une denture complémentaire d'un sabot logé dans le carter de manière à pouvoir coulisser légèrement dans le sens transversal lorsque l'embout de gaine se déplace parallèlement au câble, des moyens étant prévus pour maintenir les sabots en appui élastique contre les faces dentées des embouts associés.According to the invention, each sheath end piece is provided on one of its faces with a toothing extending parallel to the cable and which meshes with a complementary toothing of a shoe housed in the casing so as to be able to slide slightly in the transverse direction when the sheath end piece moves parallel to the cable, means being provided to keep the shoes in elastic support against the toothed faces of the associated end pieces.

Ainsi, lorsqu'un faible jeu apparait et que l'un des brins du câble est "mou", le ressort de compression en cause repousse légèrement l'embout correspondant dont la denture glisse sur les dents du sabot qui s'écarte légèrement, ce qui assure la tension du câble par progression d'un pas de la denture de l'embout sur celle du sabot.Thus, when a slight clearance appears and one of the strands of the cable is "soft", the compression spring in question slightly pushes the corresponding end piece whose teeth slide on the teeth of the shoe which deviates slightly, this which ensures the tension of the cable by progression of a step of the teeth of the end piece on that of the shoe.

Tout jeu élastique est ainsi supprimé, à l-'exception du jeu correspondant à un pas de la denture, c'est-à-dire en pratique d'un à deux millimètres.Any elastic play is thus eliminated, with the exception of play corresponding to a pitch of the toothing, that is to say in practice of one to two millimeters.

Le dispositif illustré aux Figures 1 à 3 est destiné à assurer la tension d'un câble 1 unidirectionnel de lève-vitre de véhicule automobile (câble Bowden) pouvant coulisser sur un rail 2 de manière à faire monter ou descendre une vitre non représentée.The device illustrated in Figures 1 to 3 is intended to ensure the tension of a unidirec cable 1 motor vehicle window regulator (Bowden cable) which can slide on a rail 2 so as to raise or lower a window not shown.

Ce dispositif comprend un carter 3 dans lequel sont logés un treuil 4 d'entrainement du câble 1, susceptible d'être entraîné, soit manuellement, soit par un moteur approprié tel qu'un motoréducteur 5, de façon connue en soi. Le carter 3, traversé de part en part par le câble 1, contient également deux embouts 5a, 5b recevant chacun une extrémité d'une gaine 6 contenant le câble 1, chaque embout 5a, 5b étant disposé dans un logement correspondant 7a, 7b du carter 3. Les embouts 5a, 5b sont positionnés de chaque côté du treuil 4 autour duquel s'enroule le câble 1-. Chaque embout 5a, 5b est soumis à la sollicitation élastique d'un ressort de compression 8a, 8b monté coaxialement au câble 1 dans le logement respectif 7a, 7b en prenant appui contre le fond de celui-ci.This device comprises a casing 3 in which are housed a winch 4 for driving the cable 1, capable of being driven, either manually, or by a suitable motor such as a geared motor 5, in a manner known per se. The casing 3, traversed right through by the cable 1, also contains two end pieces 5a, 5b each receiving one end of a sheath 6 containing the cable 1, each end piece 5a, 5b being disposed in a corresponding housing 7a, 7b of the casing 3. The end pieces 5a, 5b are positioned on each side of the winch 4 around which the cable 1- is wound. Each end piece 5a, 5b is subjected to the elastic stress of a compression spring 8a, 8b mounted coaxially with the cable 1 in the respective housing 7a, 7b while bearing against the bottom of the latter.

Dans la position de compression maximum du ressort 8a, tel que représenté sur la partie gauche de la Figure 1, l'embout associé 5a est complètement rentré à l'intérieur du logement 7a et soumis à une force maximum de la part du ressort 8a, tendant à le pousser vers l'extérieur du logement.In the maximum compression position of the spring 8a, as shown on the left-hand side of FIG. 1, the associated end piece 5a is completely retracted inside the housing 7a and subjected to a maximum force from the spring 8a, tending to push it out of the housing.

Chaque embout 5a, 5b ayant de préférence une forme parallélépipédique, est pourvu selon l'invention, sur une de ses faces, d'une denture respective 9a, 9b s'étendant parallèlement au câble 1 mais dont les dents sont trasnversales à celui-ci. Chaque denture 9a, 9b engrène avec une denture complémentaire 11a, 11b d'un sabot respectif 12a, 12b logé dans le carter 3 de manière à pouvoir coulisser légèrement dans le sens transversal au câble 1, lorsque l'embout correspondant 5a, 5b se déplace parallèlement au câble 1. Des moyens sont en outre prévus pour maintenir les sabots 12a, 12B en appui élastique contre les faces dentées 9a, 9b des embouts associés 5a, 5b.Each end piece 5a, 5b preferably having a parallelepiped shape, is provided according to the invention, on one of its faces, with a respective toothing 9a, 9b extending parallel to the cable 1 but the teeth of which are transverse thereto . Each toothing 9a, 9b meshes with a complementary toothing 11a, 11b of a respective shoe 12a, 12b housed in the casing 3 so as to be able to slide slightly in the transverse direction to the cable 1, when the corresponding endpiece 5a, 5b moves parallel to the cable 1. Means are also provided for maintaining the shoes 12a, 12B in elastic abutment against the toothed faces 9a, 9b of the associated end pieces 5a, 5b.

Dans la forme de réalisation représentée, ces moyens de maintien élastique des sabots 12a, 12b contre les dentures 9a, 9b sont constitués par un ressort à lame 13 solidarisé avec le carter 3 par tout moyen approprié connu en soi tel qu'une pièce 14, et qui comprend deux extrémités opposées 13a, 13b en appui élastique respectivement contre les sabots 12a, 12b.In the embodiment shown, these elastic retaining means of the shoes 12a, 12b against the teeth 9a, 9b consist of a leaf spring 13 secured to the casing 3 by any suitable means known per se such as a part 14, and which comprises two opposite ends 13a, 13b in elastic support respectively against the shoes 12a, 12b.

Le fonctionnement de ce dispositif est le suivant.The operation of this device is as follows.

Les ressorts 8a, 8b assurant la tension du câble 1 dans les deux sens de la manoeuvre de celui-ci, lorsque l'un des brins du câble 1 est moteur, la gaine 6 exerce sur l'embout 5a ou 5b correspondant un effort de compression. Cet effort est transmis par la denture 9a ou 9b au sabot 12a ou 12b qui le transmet à son tour au carter 3. Au départ, les embouts 5a, 5b sont enfoncés au maximum dans leur logement 7a, 7b, en butée contre le fond de celui-ci avec leur ressort respectif 8a, 8b comprimé au maximum, à spires jointives comme illustré sur la partie gauche de la Figure 1.The springs 8a, 8b ensuring the tension of the cable 1 in both directions of the operation thereof, when one of the strands of the cable 1 is motor, the sheath 6 exerts on the end piece 5a or 5b corresponding an effort of compression. This force is transmitted by the toothing 9a or 9b to the shoe 12a or 12b which in turn transmits it to the casing 3. At the start, the end pieces 5a, 5b are driven as far as possible into their housing 7a, 7b, abutting against the bottom of this one with their respective spring 8a, 8b compressed at the maximum, with contiguous turns as illustrated on the left part of Figure 1.

Lorsque le brin 1a de gauche sur la Figure 1 du câble 1 est moteur, la partie correspondante de la gaine 6 exerce sur l'embout 5a un effort de compression F qui tend à le maintenir dans sa position à l'intérieur du logement 7a. Les dentures 9a, 11a sont inclinées dans le sens qui s'oppose à cette force F, qui a donc pour effet de maintenir en prise les dentures correspondantes 9a et 11a. Les dentures 9b, 11b sont inclinées dans le sens opposé à celui des deux autres dentures 9a, 11a. Les parties terminales 13a, 13b du ressort 13 n'assurent aucune fonction de rétention, mais seulement le maintien en contact des sabots 12a, 12b avec les embouts 5a, 5B.When the strand 1a on the left in FIG. 1 of the cable 1 is motor, the corresponding part of the sheath 6 exerts on the endpiece 5a a compressive force F which tends to maintain it in its position inside the housing 7a. The teeth 9a, 11a are inclined in the direction which opposes this force F, which therefore has the effect of keeping the corresponding teeth 9a and 11a in engagement. The teeth 9b, 11b are inclined in the opposite direction to that of the other two teeth 9a, 11a. The end portions 13a, 13b of the spring 13 do not perform any function of retention, but only the maintenance in contact of the shoes 12a, 12b with the tips 5a, 5B.

Dans le sens inverse du précédent, le brin considéré du câble 1 est "mou", de sorte que la partie correspondante de la gaine 6 n'exerce plus sur l'embout d'effort de compression. Le ressort considéré (8a ou 8B) peut alors repousser l'embout 5à ou 5b de façon à tendre le câble 1. Les dentures 9a, 11a et 9b, 11b sont orientées comme déjà indiqué dans le sens qui permet le glissement de l'embout 5a ou 5b vers l'extérieur du logement 7a ou 7b. Le ressort 8a ou 8b exerce alors sur l'embout 5a ou 5b une poussée qui provoque un léger déplacement transversal du sabot 12a ou 11b à l'encontre de la force de rappel élastique de l'extrémité 13a ou 13b du ressort 13, jusqu'à ce que la denture 9a ou 9b ait avancé d'un cran par rapport à la denture 11a ou 11b, le câble 1 étant à nouveau tendu au terme de cette avance de l'embout 5a ou 5b.In the opposite direction to the previous one, the strand considered of the cable 1 is "soft", so that the corresponding part of the sheath 6 no longer exerts on the end piece of the compression force. The spring considered (8a or 8B) can then push the end piece 5a or 5b so as to tension the cable 1. The teeth 9a, 11a and 9b, 11b are oriented as already indicated in the direction which allows the end piece to slide. 5a or 5b towards the outside of the housing 7a or 7b. The spring 8a or 8b then exerts on the end piece 5a or 5b a push which causes a slight transverse displacement of the shoe 12a or 11b against the elastic return force of the end 13a or 13b of the spring 13, until that the teeth 9a or 9b have advanced one notch with respect to the teeth 11a or 11b, the cable 1 being stretched again after this advance of the end piece 5a or 5b.

On a représenté à la partie droite de la Figure 1 l'embout 5b dans sa position de rattrapage de jeu maximum, le ressort 8b étant partiellement détendu et la gaine 6 tendue étant représentée en traits continus, alors que dans la position d'enfoncement maximum de l'embout 5b la position tendue 6a de la gaine est représentée en traits mixtes. Sur la partie gauche de la Figure 1, la gaine et son câble 1a sont représentés en traits continus; tendus en position initiale, et en traits mixtes tendus après coulissement de l'embout 5a sur le sabot 12a.The right-hand part of FIG. 1 shows the end piece 5b in its position for taking up maximum play, the spring 8b being partially relaxed and the tight sheath 6 being shown in solid lines, while in the maximum insertion position of the nozzle 5b the stretched position 6a of the sheath is shown in phantom. On the left side of Figure 1, the sheath and its cable 1a are shown in solid lines; stretched in the initial position, and in dashed lines stretched after sliding of the end piece 5a on the shoe 12a.

Durant le fonctionnement de ce dispositif, le ressort à lame 13 travaille peu, ce qui peut permettre, en variante, de réaliser l'ensemble des deux sabots 12a, 12b et du ressort 13 en une seule pièce en plastique moulé.During the operation of this device, the leaf spring 13 works little, which may allow, as a variant, to produce all of the two shoes 12a, 12b and the spring 13 in a single piece of molded plastic.

En position initiale, les deux ressorts 8a, 8b sont comprimés à spires jointives au maximum, comme visible à la partie gauche de la Figure 2. Quand un jeu à rattraper apparaît, le ressort concerné pousse l'embout associé d'un cran, ce qui maintient le câble 1 tendu et assure la rigidité de la liaison dans le sens de la compression de la gaine 6 entre l'embout et son carter 3 de support. De ce fait, lorsqu'on appuie sur la vitre, il n'est plus possible de la faire descendre que d'un jeu correspondant à un cran de la denture 9a, 9b, c'est-à-dire en fait de 1 à 2 mm au maximum.In the initial position, the two springs 8a, 8b are compressed with contiguous turns to the maximum, as visible on the left-hand side of FIG. 2. When a play to be made up appears, the spring concerned pushes the associated end piece by a notch, this which keeps the cable 1 taut and ensures the rigidity of the connection in the direction of compression of the sheath 6 between the end piece and its support casing 3. Therefore, when the window is pressed, it is no longer possible to lower it except by a clearance corresponding to a notch of the teeth 9a, 9b, that is to say in fact from 1 to 2 mm maximum.

En variante, le ressort 13 pourrait être remplacé par deux ressorts distincts agissant chacun sur un sabot 12a, 12b. De même, le treuil 4 peut être entraîné manuellement comme déjà indiqué, l'invention n'étant pas limitée aux lève-vitre électriques.Alternatively, the spring 13 could be replaced by two separate springs each acting on a shoe 12a, 12b. Likewise, the winch 4 can be driven manually as already indicated, the invention not being limited to electric windows.
