Description

Domaine de l'inventionField of the invention

L'invention se rapporte à un banc de redressage pour le châssis et la carrosserie d'un véhicule.The invention relates to a straightening bench for the frame and the body of a vehicle.

L'invention se rapporte aussi à des moyens de fixation pour fixer le véhicule à un banc de redressage.The invention also relates to fastening means for fixing the vehicle to a straightening bench.

État de la techniqueState of the art

On connaît le document US 7,076,988 qui dévoile un banc de redressage pour le châssis et la carrosserie d'un véhicule comprenant une table de redressage et une poutre de redressage. La table de redressage est montée sur un croisillon élévateur. Une fois le véhicule positionné sur la table de redressage et fixé à celle-ci, le croisillon permet de le surélever en vue du travail de redressage à effectuer. Dans un tel appareil, le véhicule une fois surélevé ne repose plus sur ses roues, ce qui limite l'utilisation de l'appareil aux seules tâches de redressage. Le mesurage du châssis du véhicule pour évaluer l'avancement du travail de redressage nécessite en effet le déplacement du véhicule sur un autre appareil dans lequel le véhicule est posé sur ses roues.We know the document US 7,076,988 which unveils a straightening bench for the chassis and the body of a vehicle comprising a straightening table and a straightening beam. The straightening table is mounted on a lifting spider. Once the vehicle is positioned on the straightening table and fixed thereto, the spider makes it possible to raise it for the straightening work to be performed. In such an apparatus, the vehicle once raised is no longer based on its wheels, which limits the use of the device to straightening tasks. The measurement of the vehicle chassis to evaluate the progress of the straightening work indeed requires the movement of the vehicle on another device in which the vehicle is placed on its wheels.

On connaît également le document WO2009/095533 décrivant un banc de redressage comprenant également un croisillon élévateur mais aussi des plans destinés à accueillir les roues du véhicule une fois celui-ci surélevé. Dans un tel appareil, le véhicule peut donc reposer sur ses roues une fois surélevé et des travaux autres que ceux du redressage du châssis et de la carrosserie peuvent être effectués sur le véhicule. La présence du croisillon élévateur sous la table de redressage limite cependant les possibilités de travailler sur le véhicule et génère un encombrement empêchant l'utilisation de certains appareils tels que des mesureurs de châssis à ultrasons qui nécessite la présence d'une règle sous le véhicule.The document is also known WO2009 / 095533 describing a straightening bench also comprising a lifting spider but also plans for accommodating the wheels of the vehicle once it raised. In such an apparatus, the vehicle can therefore rest on its wheels once raised and work other than straightening the chassis and bodywork may be performed on the vehicle. The presence of the lift brace under the straightening table, however, limits the possibilities of working on the vehicle and generates a footprint that prevents the use of certain devices such as ultrasonic chassis meters that requires the presence of a ruler under the vehicle.

Résumé de l'inventionSummary of the invention

Un but de l'invention est de fournir un banc de redressage permettant d'effectuer à la fois les opérations de redressage en elles-mêmes et également de mesurer l'effet desdites opérations de redressage sur le châssis de véhicule sans devoir déplacer le véhicule.An object of the invention is to provide a straightening bench for performing both the straightening operations in themselves and also to measure the effect of said straightening operations on the vehicle chassis without having to move the vehicle.

Un autre but de l'invention est de fournir un appareil permettant d'effectuer tout type de travaux sur un véhicule : redressage du véhicule, travaux mécaniques, réglage des phares, mesure du châssis et géométrie du véhicule.Another object of the invention is to provide an apparatus for carrying out any type of work on a vehicle: straightening of the vehicle, mechanical work, adjustment of the headlights, measurement of the chassis and geometry of the vehicle.

A cette fin, le banc de redressage pour le châssis et la carrosserie d'un véhicule selon l'invention comprend au moins une équerre de redressage et comprend également :

  • Un pont élévateur comprenant quatre poutres, lesdites quatre poutres comprenant deux poutres longitudinales et deux poutres transversales reliées deux à deux, chacune des deux poutres transversales étant reliée à deux colonnes de levage,
  • Des moyens de fixation du véhicule aux poutres longitudinales du banc de redressage,
ladite au moins une équerre de redressage étant attachée à une desdites quatre poutres.To this end, the straightening bench for the frame and the body of a vehicle according to the invention comprises at least one straightening square and also comprises:
  • A lift comprising four beams, said four beams comprising two longitudinal beams and two transverse beams connected in pairs, each of the two transverse beams being connected to two lifting columns,
  • Means for fixing the vehicle to the longitudinal beams of the straightening bench,
said at least one straightening square being attached to one of said four beams.

Le banc de redressage selon l'invention peut donc être utilisé comme un pont élévateur à quatre colonnes classique une fois les roues du véhicule placées sur les poutres longitudinales. Cela permet de réaliser tout type de travaux mécaniques, étant donné que le mécanicien dispose d'un espace de travail optimal sous le véhicule, une fois ce dernier surélevé grâce aux colonnes de levage de l'appareil.The straightening bench according to the invention can therefore be used as a conventional four-post lift once the wheels of the vehicle placed on the longitudinal beams. This makes it possible to carry out any type of mechanical work, since the mechanic has an optimal working space under the vehicle, once the latter is raised thanks to the lifting columns of the apparatus.

La présence de l'équerre de redressage et des moyens de fixation du véhicule au banc de redressage permet par ailleurs de réaliser les travaux de redressage de châssis et de carrosserie attendus pour un banc de redressage classique, grâce à des chaines ou des cordes attachées à l'équerre de redressage. Dans le banc de redressage selon l'invention, le véhicule restera cependant tout le temps posé sur ses roues, à la différence des bancs de redressage dévoilés dans l'art antérieur. Cette dernière caractéristique permet d'intégrer au banc de redressage selon l'invention des appareils de géométrie des roues du véhicule et de réglage des phares. Ces appareils, pour pouvoir être utilisés, nécessitent en effet que le véhicule soit posé sur ses roues.The presence of the straightening bracket and the means of fixing the vehicle to the straightening bench also makes it possible to carry out the straightening work on the chassis and the bodywork expected for a conventional straightening bench, thanks to chains or strings attached to the straightening square. In the straightening bench according to the invention, however, the vehicle will remain all the time on its wheels, unlike the straightening benches disclosed in the prior art. This last feature makes it possible to integrate vehicle wheel alignment and headlight adjustment devices in the straightening bench according to the invention. These devices, to be used, indeed require that the vehicle is placed on its wheels.

Par ailleurs, l'espace de travail dégagé sous le véhicule, une fois ce dernier surélevé, permet de mettre en place un appareil de mesure de châssis à ultrasons. De cette manière, les travaux de redressage et de mesurage du châssis du véhicule peuvent être effectués de manière concomitante sans devoir déplacer le véhicule sur un autre appareil.In addition, the work space underneath the vehicle, once raised, allows to set up an ultrasonic chassis measuring device. Of In this way, straightening and measuring work on the vehicle chassis can be carried out concomitantly without having to move the vehicle to another device.

En conséquence, le banc de redressage selon l'invention permet de réaliser de multiples tâches en un seul et même lieu, sans changer de place le véhicule.Consequently, the straightening bench according to the invention makes it possible to perform multiple tasks in one and the same place, without changing the vehicle's position.

Selon un mode de réalisation avantageux, le banc de redressage selon l'invention comprend des moyens pour faire varier la distance entre les poutres longitudinales. De tels moyens comprennent avantageusement des rails sur les poutres transversales sur lesquels les poutres longitudinales peuvent coulisser.According to an advantageous embodiment, the straightening bench according to the invention comprises means for varying the distance between the longitudinal beams. Such means advantageously comprise rails on the transverse beams on which the longitudinal beams can slide.

Ce mode de réalisation permet avantageusement d'adapter l'espacement entre les poutres longitudinales aux dimensions du véhicule à réparer. Ainsi, des véhicules de largeur variable peuvent être réparés sur un même banc de redressage.This embodiment advantageously makes it possible to adapt the spacing between the longitudinal beams to the dimensions of the vehicle to be repaired. Thus, vehicles of variable width can be repaired on the same straightening bench.

Selon un mode de réalisation avantageux, ladite équerre de redressage est attachée à ladite poutre à l'aide de moyens de fixation amovibles.According to an advantageous embodiment, said straightening bracket is attached to said beam by means of removable fastening means.

Dans ce mode de réalisation, l'équerre de redressage pourra en effet être déplacée à différents endroits sur les poutres du banc de redressage, ce qui permettra de la déplacer en fonction des zones du châssis ou de la carrosserie à redresser.In this embodiment, the straightening bracket can indeed be moved to different places on the straightening bench beams, which will move it depending on the areas of the chassis or the body to straighten.

Selon un mode de réalisation avantageux, les poutres du banc de redressage selon l'invention sont des poutres en I, la partie centrale desdites poutres ayant une largeur suffisante pour permettre le roulement d'un pneu dudit véhicule et les parties latérales étant percées de trous à intervalles réguliers.According to an advantageous embodiment, the beams of the straightening bench according to the invention are I-beams, the central part of said beams having a width sufficient to allow the rolling of a tire of said vehicle and the side parts being pierced with holes. at regular intervals.

Dans ce mode de réalisation, les trous constituent des moyens de fixation pratiques pour les équerres de redressage et pour d'éventuels autres outils ou instruments à utiliser en combinaison avec le banc de redressage.In this embodiment, the holes constitute practical fastening means for the straightening brackets and for any other tools or instruments to be used in combination with the straightening bench.

Selon un mode de réalisation avantageux, les moyens de fixation amovibles de l'équerre de redressage comprennent des tiges insérées dans les trous d'une desdites poutres en I.According to an advantageous embodiment, the removable fastening means of the straightening bracket comprise rods inserted into the holes of one of said I-beams.

Selon un mode de réalisation avantageux, des rails sont fixés sur lesdites poutres en I, les équerres de redressage étant aptes à coulisser sur lesdits rails.According to an advantageous embodiment, rails are fixed on said I-beams, the straightening brackets being able to slide on said rails.

Dans ce mode de réalisation, les équerres de redressage peuvent être déplacées le long des poutres du banc de redressage et donc être positionnées de manière optimale en fonction de la spécificité des travaux de redressage à effectuer.In this embodiment, the straightening brackets can be moved along the beams of the straightening bench and therefore be positioned optimally according to the specificity of the straightening work to be performed.

Selon un mode de réalisation avantageux, le banc de redressage selon l'invention comprend un vérin hydraulique fixé sur une desdites quatre poutres, ledit vérin étant apte à exercer un effort vertical sur un point de véhicule compris dans le périmètre défini par lesdites quatre poutres.According to an advantageous embodiment, the straightening bench according to the invention comprises a hydraulic jack fixed on one of said four beams, said jack being able to exert a vertical force on a vehicle point included in the perimeter defined by said four beams.

Dans ce mode de réalisation, ledit vérin permet, en outre de pouvoir être utilisé comme moyen de redressage, de soulever le châssis du véhicule à proximité d'une roue dans le but de changer ladite roue. Selon un mode de réalisation avantageux, le banc de redressage selon l'invention comprend une règle pour le calibrage d'un système de mesure du châssis du véhicule par ultrasons fixée entre lesdites poutres longitudinales au moyen de poutres transversales reliant les poutres longitudinales deux à deux.In this embodiment, said jack makes it possible, in addition to being used as a straightening means, to lift the chassis of the vehicle close to a wheel in order to change said wheel. According to an advantageous embodiment, the straightening bench according to the invention comprises a rule for the calibration of an ultrasonic vehicle chassis measurement system fixed between said longitudinal beams by means of transverse beams connecting the longitudinal beams two by two. .

Ce mode de réalisation réunit donc en un seul appareil les fonctions de redressage et de mesure du châssis, ce qui offre des conditions de travail optimales car le véhicule ne doit pas être déplacé sur un autre appareil pour évaluer l'effet des travaux de redressage. Il en résulte une facilité d'utilisation et un gain de temps considérable pour le carrossier.This embodiment therefore combines the straightening and measuring functions of the chassis in a single device, which offers optimal working conditions because the vehicle must not be moved to another device to evaluate the effect of the straightening work. This results in ease of use and considerable time savings for the bodybuilder.

Selon un mode de réalisation avantageux, le banc de redressage selon l'invention comprend un système pour mesurer la géométrie des roues du véhicule intégré sur lesdites poutres longitudinales du banc de redressage. Un tel système peut donc être directement intégré au banc de redressage selon l'invention car le véhicule est posé sur ses roues sur les poutres longitudinales.According to an advantageous embodiment, the straightening bench according to the invention comprises a system for measuring the geometry of the wheels of the integrated vehicle on said longitudinal beams of the straightening bench. Such a system can be directly integrated into the straightening bench according to the invention because the vehicle is placed on its wheels on the longitudinal beams.

L'approche innovante du banc de redressage selon l'invention qui consiste à garder le véhicule posé sur ses roues en toutes circonstances offre donc la possibilité d'effectuer tout type de travaux mécaniques sur le véhicule sans devoir déplacer ce dernier sur d'autres appareils. Le banc de redressage selon l'invention est donc en réalité un appareil multitâche dont le design permet de rassembler en une seule structure un ensemble d'outils et d'instruments qui ne pouvaient pas être utilisés de manière concomitante dans l'art antérieur.The innovative approach of the straightening bench according to the invention which consists in keeping the vehicle on its wheels under all circumstances thus offers the possibility of carrying out any type of mechanical work on the vehicle without having to move the latter on other apparatus. . The straightening bench according to the invention is therefore in reality a multitasking apparatus whose design allows to gather in a single structure a set of tools and instruments that could not be used concomitantly in the prior art.

Un autre but de l'invention est de fournir des moyens d'attache d'un véhicule à un banc de redressage s'adaptant à tout type de carrosserie et de châssis de véhicule et étant par ailleurs facilement et rapidement mis en place tout en offrant une fiabilité importante.Another object of the invention is to provide means for attaching a vehicle to a straightening bench adapted to any type of body and vehicle chassis and is also easily and quickly implemented while offering important reliability.

A cette fin, l'attache pour la fixation d'un véhicule à un banc de redressage selon l'invention comprend une tige, une rainure étant usinée à l'une des extrémités de ladite tige, ladite rainure divisant l'extrémité de ladite tige en deux jambes, chacune des deux jambes comprenant un trou traversant, lesdits deux trous traversants se faisant face, et comprend également une première mâchoire, ladite première mâchoire étant insérée dans ladite rainure, ladite première mâchoire comprenant un trou traversant faisant face aux trous traversants des jambes de ladite tige, et une seconde mâchoire en C comprenant une partie concave, une jambe de ladite tige étant insérée dans la partie concave de la seconde mâchoire, lesdites mâchoires comprenant une pluralité de trous traversants se faisant face deux à deux, des boulons étant insérés dans lesdits trous traversants pour fixer la première mâchoire à ladite tige et pour fixer la seconde mâchoire à la première mâchoire.To this end, the fastener for fixing a vehicle to a straightening bench according to the invention comprises a rod, a groove being machined at one end of said rod, said groove dividing the end of said rod in two legs, each of the two legs including a through-hole, said two through-holes facing each other, and also includes a first jaw, said first jaw being inserted into said groove, said first jaw including a through hole facing the through-holes of legs of said rod, and a second C-jaw including a concave portion, a leg of said rod being inserted into the concave portion of the second jaw, said jaws including a plurality of through holes facing each other in pairs, bolts being inserted into said through holes to secure the first jaw to said rod and to secure the second jaw to the first m jaw.

Un telle attache s'est en effet révélée particulièrement efficace pour se fixer au renfort de longeron d'un véhicule (=feuillure de bas de caisse) puisque ladite tige peut être montée en rotation sur une poutre du banc de redressage selon l'invention, ce qui permet d'orienter les mâchoires suivant l'axe des renforts de longeron du véhicule à fixer au banc de redressage. Ainsi, des voitures ayant un profil fuselé, et donc des renforts de longeron droits et gauches non parallèles peuvent être fixées sans difficulté à un banc de redressage à l'aide des moyens de fixation selon l'invention. Par ailleurs, la possibilité de faire varier l'orientation des mâchoires par rapport à l'axe défini par les trous traversants percés dans les deux jambes de la tige permet de conserver la fixation du véhicule au banc de redressage même lorsque le châssis du véhicule est surélevé en un seul endroit. De plus, en raison du design particulier de l'attache selon l'invention, lesdites première et seconde mâchoires grâce à leurs trous traversants se faisant face peuvent être rapprochées l'une de l'autre tout en restant parallèles grâce au vissage de boulons et d'écrous, ce qui permet de maximiser l'aire de la zone de serrage et la force de serrage entre les deux mâchoires et donc la fiabilité de l'attache selon l'invention. Cet effet n'est pas observé pour les attaches de l'art antérieur dont la zone de serrage résulte d'une rotation et non d'une translation des première et seconde mâchoires.Such a fastener has indeed proved particularly effective for attaching to the reinforcement of a spar of a vehicle (= rebate of sill) since said rod can be rotatably mounted on a beam of the straightening bench according to the invention, which allows to orient the jaws along the axis of the vehicle spar reinforcements to be fixed to the straightening bench. Thus, cars having a tapered profile, and therefore non-parallel right and left spar reinforcements can be fixed without difficulty to a straightening bench using the fastening means according to the invention. Moreover, the possibility of varying the orientation of the jaws relative to the axis defined by the through holes drilled in the two legs of the rod makes it possible to maintain the attachment of the vehicle to the straightening bench even when the chassis of the vehicle is raised in one place. In addition, because of the particular design of the fastener according to the invention, said first and second jaws with their through holes facing each other can be brought closer to each other while remaining parallel thanks to screwing bolts and of nuts, which maximizes the area of the clamping zone and the clamping force between the two jaws and therefore the reliability of the fastener according to the invention. This effect is not observed for the fasteners of the prior art whose clamping zone results from a rotation and not from a translation of the first and second jaws.

Selon un mode de réalisation avantageux, la tige de l'attache selon l'invention est filetée. Un tel filetage permettra en effet une fixation aisée de celle-ci à une poutre d'un banc de redressage.According to an advantageous embodiment, the rod of the fastener according to the invention is threaded. Such threading will indeed allow easy attachment thereof to a beam of a straightening bench.

Selon un mode de réalisation avantageux, de telles attaches sont fixées aux poutres longitudinales en I du banc de redressage selon l'invention par l'intermédiaire de pièces en U comprenant un trouAccording to an advantageous embodiment, such fasteners are fixed to the longitudinal beams I of the straightening bench according to the invention by means of U-shaped pieces comprising a hole

De telles attaches ne peuvent cependant être directement utilisées que si le véhicule dispose de renforts de longeron appropriés, c'est-à-dire aptes à être enserrés fermement par les mâchoires de l'attache. En l'absence de tels renforts de longerons, lesdites attaches ne peuvent pas être utilisées efficacement.Such fasteners can, however, be used directly only if the vehicle has appropriate reinforcements spar, that is to say, able to be firmly gripped by the jaws of the fastener. In the absence of such reinforcements of spars, said fasteners can not be used effectively.

Par conséquent, un autre but de l'invention est de fournir des moyens fixer tout type de véhicules au banc de redressage.Therefore, another object of the invention is to provide means to fix any type of vehicle to the straightening bench.

A cette fin, le kit d'ancrage au châssis d'un véhicule pour une attache de fixation à un banc de redressage selon l'invention comprend :

  • au moins deux tiges, chaque tige comprenant une tête d'ancrage pour un trou de support de cric dudit véhicule ;
  • au moins une poutre comprenant deux trous traversants, la distance (D) entre lesdits deux trous traversants étant égale à la distance entre le trou de support de cric avant et le trou de support de cric arrière dudit véhicule, le diamètre desdits trous traversants étant suffisant pour permettre le passage desdites au moins deux tiges;
  • des moyens de fixation pour fixer ladite au moins une poutre auxdites au moins deux tiges ancrées au châssis du véhicule.
To this end, the chassis anchoring kit of a vehicle for a fastening attachment to a straightening bench according to the invention comprises:
  • at least two rods, each rod comprising an anchor head for a jack support hole of said vehicle;
  • at least one beam comprising two through holes, the distance (D) between said two through holes being equal to the distance between the front jack support hole and the rear jack support hole of said vehicle, the diameter of said through holes being sufficient to allow the passage of said at least two rods;
  • fastening means for fixing said at least one beam to said at least two rods anchored to the chassis of the vehicle.

Le châssis d'un véhicule est en effet en général muni de trous percés dans ses longerons, en général protégés par des caches, destinés à accueillir un cric lors du changement d'une roue. De manière surprenante, il a pu être constaté que ces trous pouvaient être détournés de leur fonction première et être utilisés pour attacher le véhicule au banc de redressage. Ces trous sont effet percés dans une partie très solide du châssis du véhicule et constituent par conséquent un endroit approprié pour insérer des tiges munies de têtes d'ancrage.The chassis of a vehicle is in fact generally provided with holes drilled in its longitudinal members, generally protected by caches, intended to accommodate a jack when changing a wheel. Surprisingly, it has been found that these holes could be diverted from their primary function and used to attach the vehicle to the straightening bench. These holes are pierced in a very solid part of the chassis of the vehicle and therefore constitute an appropriate place to insert rods with anchor heads.

Les têtes d'ancrage des tiges filetées doivent être conçues de telle manière qu'elles puissent être insérées dans les trous de support de cric tout en restant ancrées à l'intérieur de ceux-ci une fois positionnée à l'intérieur de ceux-ci. La tête d'ancrage et donc la tige doivent par conséquent être adaptées au modèle particulier du véhicule à fixer au banc de redressage.The anchor heads of the threaded rods must be designed so that they can be inserted into the jackhole holes while remaining anchored within them when positioned within them . The anchoring head and therefore the rod must therefore be adapted to the particular model of the vehicle to be fixed to the straightening bench.

La poutre comprend quant à elle avantageusement des moyens pour faire varier la distance entre lesdits deux trous traversants, ce qui lui permet d'être utilisée pour des modèles de véhicules différents qui possèdent donc un espacement différent entre leurs trous de support de cric.The beam advantageously comprises means for varying the distance between said two through holes, which allows it to be used for different vehicle models which therefore have a different spacing between their jack support holes.

Selon un mode de réalisation avantageux, les au moins deux tiges du kit d'ancrage sont filetées et les moyens de fixation desdites tiges à la poutre comprennent des écrous.According to an advantageous embodiment, the at least two rods of the anchoring kit are threaded and the fixing means of said rods to the beam comprise nuts.

Dans ce mode de réalisation, une fois la tête des tiges filetées introduite dans les trous du support de cric du véhicule, la poutre du kit d'ancrage peut être fixée au véhicule en introduisant les tiges filetées dans les trous traversants de la poutre et en les fixant à l'aide d'écrous.In this embodiment, once the head of the threaded rods is inserted into the holes of the vehicle jack support, the beam of the anchoring kit can be fixed to the vehicle by introducing the threaded rods into the through holes of the beam and fixing them with nuts.

Selon un autre mode de réalisation, les tiges d'ancrage sont percées de trous et des goupilles sont utilisées pour fixer lesdites tiges à ladite poutre une fois les têtes d'ancrage introduites dans les trous de support de cric.In another embodiment, the anchor rods are drilled with holes and pins are used to secure said rods to said beam once the anchor heads are introduced into the jack support holes.

Une fois des poutres solidarisées aux flancs droit et gauche du véhicule, ces dernières peuvent être directement fixées au banc de redressage à l'aide des attaches exposées précédemment.Once beams are secured to the left and right sides of the vehicle, the latter can be directly attached to the straightening bench using the previously exposed fasteners.

L'invention porte donc également sur l'utilisation de trous de support de cric d'un véhicule comme moyens de fixation dudit véhicule à un banc de redressage.The invention therefore also relates to the use of vehicle jack support holes as means for fixing said vehicle to a straightening bench.

Description détaillée de modes de réalisation particuliersDetailed description of particular embodiments

Les Fig. 1 et Fig. 2 représentent un mode de réalisation du banc de redressage selon l'invention. Le banc de redressage comprend quatre colonnes de levage 1, deux poutres transversales 2b reliées aux colonnes de levage 1, de même que deux poutres longitudinales 2a reliées aux poutres transversales 2b et destinées à recevoir les roues du véhicule à réparer. Des moyens d'attache 4 du véhicule aux poutres longitudinales 2a du banc de redressage sont présents en vue d'immobiliser le véhicule pour les travaux de redressage. Les équerres de redressage comprennent des vérins hydrauliques pour se déplacer dans les trois dimensions de l'espace et ainsi permettre le redressage du châssis ou de la carrosserie une fois munies de chaines ou de câbles. Les poutres longitudinales 2a et transversales 2b du banc de redressage sont des poutres en I. La largeur de la partie centrale des poutres longitudinales 2a est suffisante pour accueillir le pneu du véhicule à réparer. Les parties latérales des poutres en I sont munies de trous traversants percés à intervalles réguliers. De tels trous sont utilisés pour la fixation de pièces en U 40, auxquelles sont fixées les attaches 4, et également pour la fixation de rails 5 sur lesquels coulissent les équerres de redressage 3. Les colonnes de levage 1 du banc de redressage sont munies de vis sans fin. De plus, les poutres longitudinales 2a peuvent coulisser le long des poutres transversales 2b, de manière à adapter l'espacement entres les poutres longitudinales 2a à la largeur spécifique du véhicule à réparer.The Fig. 1 and Fig. 2 represent an embodiment of the straightening bench according to the invention. The straightening bench comprises four lifting columns 1, two transverse beams 2b connected to the lifting columns 1, as well as two longitudinal beams 2a connected to the transverse beams 2b and intended to receive the wheels of the vehicle to be repaired. Fastening means 4 of the vehicle longitudinal beams 2a of the straightening bench are present to immobilize the vehicle for straightening work. The straightening brackets include hydraulic cylinders to move in three dimensions of the space and thus allow the straightening of the frame or the body once provided with chains or cables. The longitudinal beams 2a and 2b of the transverse straightening bench are I-beams. The width of the central portion of the longitudinal beams 2a is sufficient to accommodate the tire of the vehicle to be repaired. The lateral parts of I-beams are provided with through holes drilled at regular intervals. Such holes are used for fastening U-shaped pieces 40 to which the fasteners 4 are fastened, and also for fixing rails 5 on which the straightening brackets 3 slide. The lifting columns 1 of the straightening bench are provided with worm. In addition, the longitudinal beams 2a can slide along the transverse beams 2b, so as to adapt the spacing between the longitudinal beams 2a to the specific width of the vehicle to be repaired.

La Fig. 3 représente en détails un mode de réalisation de l'attache utilisée pour fixer le véhicule au banc de redressage. L'attache comprend une tige 10 ayant une rainure 11 usinée à l'une de ses extrémités. La rainure 11 divise l'extrémité de la tige 10 en deux jambes 12a et 12b, chacune des deux jambes comprenant un trou traversant 13a et 13b, les deux trous traversants 13a et 13b se faisant face.The Fig. 3 shows in detail an embodiment of the fastener used to secure the vehicle to the straightening bench. The fastener comprises a rod 10 having a groove 11 machined at one of its ends. The groove 11 divides the end of the rod 10 into two legs 12a and 12b, each of the two legs comprising a through hole 13a and 13b, the two through holes 13a and 13b facing each other.

L'attache comprend également une première mâchoire 14, ladite première mâchoire 14 étant insérée dans la rainure 11 de la tige 10. Cette première mâchoire est munie d'un trou traversant 15 qui fait face aux trous trous traversants 13a et 13b des jambes 12a et 12b de ladite tige 10. Les trous traversants 13a et 13b de la tige 10 et le trou 15 de la première mâchoire permettent de fixer la première mâchoire à la tige 10 à l'aide par exemple d'un écrou et d'un boulon aux dimensions adaptées (non représenté).The clip also includes a first jaw 14, said first jaw 14 being inserted into the groove 11 of the rod 10. This first jaw is provided with a through-hole 15 which faces the through-hole holes 13a and 13b of the legs 12a and 12b of said rod 10. The through holes 13a and 13b of the rod 10 and the hole 15 of the first jaw make it possible to fix the first jaw to the rod 10 by means of, for example, a nut and a bolt at adapted dimensions (not shown).

L'attache comprend également une seconde mâchoire 16 en C comprenant une partie concave 17, une jambe de ladite tige 12a étant insérée dans la partie concave 17 de la seconde mâchoire 16. Les mâchoires 14 et 16 comprennent par ailleurs une pluralité de trous traversants 18 et 19 se faisant face deux à deux. Ces trous traversants 18 et 19 permettent de fixer la première mâchoire 14 à la seconde mâchoire 16 à l'aide par exemple d'écrous et de boulons aux dimensions appropriées (non représenté).The fastener also comprises a second jaw 16 of C comprising a concave portion 17, a leg of said rod 12a being inserted in the concave portion 17 of the second jaw 16. The jaws 14 and 16 further comprise a plurality of through holes 18 and 19 facing each other in pairs. These through holes 18 and 19 make it possible to fix the first jaw 14 to the second jaw 16 using, for example, nuts and bolts of appropriate dimensions (not shown).

La tige 10 est avantageusement filetée (non représenté). De cette manière elle peut être aisément fixée à une poutre en I du banc de redressage selon l'invention. En effet, la pièce en U 40 représentée à la Fig. 4 peut être facilement fixée aux poutres en I du banc de redressage selon l'invention grâce à ses parties latérales 41 munies de trous traversants 42. La partie centrale 43 étant quant à elle percée d'une fente, elle peut accueillir la tige 10 qui y est fixée par un écrou.The rod 10 is advantageously threaded (not shown). In this way it can be easily attached to an I-beam of the straightening bench according to the invention. Indeed, the U-shaped piece 40 shown in FIG. Fig. 4 can be easily attached to the I-beams of the straightening bench according to the invention with its side portions 41 provided with through holes 42. The central portion 43 is in turn pierced by a slot, it can accommodate the rod 10 which there is fixed by a nut.

La Fig. 5 représente quant à elle la poutre 50 du kit d'ancrage selon l'invention destinée à coopérer avec les tiges d'ancrage 60 et 70 représentées aux Fig. 6 et 7. Cette poutre dispose donc de deux trous 51 et 52 aptes à recevoir les tiges d'ancrage 60 et 70 après que ces dernières aient été introduites dans les trous de support de cric d'un véhicule. L'espacement D entre les trous 51 et 52 doit donc correspondre à la distance entre les trous de support de cric du véhicule. Etant donné que cette distance varie d'un modèle de véhicule à l'autre, la poutre 50 du kit d'ancrage selon l'invention comprend avantageusement des moyens pour faire varier la distance entre les trous traversants 51 et 52. Dans le mode de réalisation représenté à la Fig. 5, la poutre 50 est constituée de deux poutres 53 et 54 solidarisées entre elles par des moyens de fixations 55 et 56, permettant de régler la longueur de la poutre 50 en faisant varier la portion des poutres 53 et 54 se chevauchant. D'autres moyens pourraient cependant être utilisés pour rendre une même poutre 50 adaptable à différents modèles de véhicules, tels que par exemple une poutre 50 en une seule pièce percée de trous traversants à différents intervalles correspondants aux dimensions standards des véhicules à fixer au banc de redressage.The Fig. 5 represents for its part the beam 50 of the anchoring kit according to the invention intended to cooperate with the anchor rods 60 and 70 shown in FIGS. Fig. 6 and 7 . This beam thus has two holes 51 and 52 adapted to receive the anchor rods 60 and 70 after they have been introduced into the jack support holes of a vehicle. The spacing D between the holes 51 and 52 must therefore correspond to the distance between the jack support holes of the vehicle. Since this distance varies from one vehicle model to another, the beam 50 of the anchoring kit according to the invention advantageously comprises means for varying the distance between the through holes 51 and 52. realization represented at Fig. 5 , the beam 50 consists of two beams 53 and 54 secured to each other by means of fasteners 55 and 56, for adjusting the length of the beam 50 by varying the portion of the beams 53 and 54 overlapping. Other means could, however, be used to make the same beam 50 adaptable to different vehicle models, such as for example a beam 50 in one piece pierced with through holes at different intervals corresponding to the standard dimensions of the vehicles to be fixed to the test bench. straightening.

Les Fig. 6 et Fig. 7 représentent donc deux modes de réalisation des tiges 60 et 70 utilisées dans le kit d'ancrage au châssis d'un véhicule selon l'invention. Les tiges 60 et 70 ont des têtes d'ancrage 61 et 71 différentes qui correspondent à des modes de réalisation différents destinés à des modèles de véhicule différent. En effet, tous les modèles de véhicule n'ont pas des trous de support de cric identiques et il est donc nécessaire de réaliser des tiges avec tête d'ancrage adaptées.The Fig. 6 and Fig. 7 therefore represent two embodiments of the rods 60 and 70 used in the chassis anchoring kit of a vehicle according to the invention. The rods 60 and 70 have different anchor heads 61 and 71 which correspond to different embodiments for different vehicle models. Indeed, all vehicle models do not have identical jack support holes and it is therefore necessary to produce rods with suitable anchor head.
