Description

L'invention a trait au domaine de l'automobile.The invention relates to the field of the automobile.

Pour diverses raisons, il peut être nécessaire de manoeuvrer le bloc moteur d'un véhicule automobile, en particulier pour avoir accès à la boîte de vitesses.For various reasons, it may be necessary to operate the engine block of a motor vehicle, in particular to have access to the gearbox.

Dans la chaîne de montage des véhicules, la boîte de vitesses est d'abord montée sur le moteur, puis celui-ci est inséré dans la caisse du véhicule automobile qui définit son environnement final. Le moteur est ensuite connecté aux diverses pièces auxiliaires.In the assembly line of vehicles, the gearbox is first mounted on the engine, then it is inserted into the body of the motor vehicle that defines its final environment. The motor is then connected to the various auxiliary parts.

La boîte de vitesses est l'un des éléments de transmission du groupe motopropulseur (GMP). Il est parfois nécessaire de la remplacer ou de la réparer, l'opérateur mécanicien devant alors déplacer le moteur avec sa boîte de vitesses, afin de libérer l'accès à cette dernière.The gearbox is one of the powertrain transmission elements (GMP). It is sometimes necessary to replace or repair it, the operator must then move the engine with the gearbox, to release access to the latter.

On connaît des supports de levage pour moteur et boîte de vitesses comprenant une traverse pourvue de deux ailes latérales à écartement réglable, montées coulissantes en translation sur la traverse, ces ailes formant pieds supports montés pivotant à 360° suivant un axe perpendiculaire à la traverse, chaque pied comprenant deux patins en caoutchouc venant en appui sur le bord supérieur des ailes du véhicule. La traverse comprend une ou deux tiges portant une chaîne destinée à ceinturer le moteur, le levage de la chaîne étant manuel ou non. On peut se référer, par exemple, au document EP611726 .Lifting supports for engine and gearbox are known comprising a crossbar provided with two lateral wings with adjustable spacing, mounted sliding in translation on the crossmember, these wings forming support legs mounted to pivot 360 ° along an axis perpendicular to the crossmember, each foot comprising two rubber pads bearing on the upper edge of the wings of the vehicle. The crossmember comprises one or two rods carrying a chain intended to surround the motor, the lifting of the chain being manual or not. For example, we can refer to the document EP611726 .

Les modèles de véhicules comportent de plus en plus fréquemment des éléments de carrosserie en matériau polymère, notamment des ailes avant, interdisant l'appui d'une traverse de levage sur le bord de ces ailes.More and more frequently, vehicle models include body elements made of polymeric material, in particular front fenders, which prohibit the support of a lifting beam on the edge of these wings.

En conséquence, les supports de levage pour moteur et boîte de vitesses actuellement commercialisés sont inadaptés. Faute d'équipement de levage adéquat, les opérateurs doivent employer d'une part un cric roulant pour soutenir et descendre le moteur lors de la dépose de la boîte de vitesses, et d'autre part une grue d'atelier pour soutenir la boîte de vitesses. Ces deux opérations nécessitent la présence de deux personnes et ne permettent pas de bonnes conditions de travail, tant du point de vue de l'ergonomie que de la sécurité. Il est connu du document DE 72 40 356 U un système de manutention de moteur comprenant une traverse sur laquelle est monté un bras et deux adaptateurs ayant des montants de longueur réglable dont l'extrémité inférieure est destinée à coopérer avec un élément d'une voiture.As a result, the lifting brackets for engine and gearbox currently marketed are unsuitable. In the absence of adequate lifting equipment, operators must use a rolling jack to support and lower the engine during removal of the gearbox, and secondly a workshop crane to support the gearbox. These two operations require the presence of two people and do not allow good working conditions, both from the point of view of ergonomics and security. It is known from the document DE 72 40 356 U an engine handling system comprising a cross member on which is mounted an arm and two adapters having amounts of adjustable length whose lower end is intended to cooperate with a car element.

L'invention vise à résoudre les problèmes présentés par les dispositifs de l'art antérieur.The invention aims to solve the problems presented by the devices of the prior art.

La sécurité du mécanicien et la simplicité du dispositif de manutention sont également des objectifs poursuivis.The safety of the mechanic and the simplicity of the handling device are also objectives pursued.

A cet effet, il est proposé, en premier lieu, un système de manutention d'un bloc moteur, ce système de manutention comprenant une traverse, un bras de maintien monté sur la traverse, et au moins deux patins montés sur la traverse et positionnés de part et d'autre du bras de maintien, ce système comprenant :

  • une paire d'adaptateurs, chaque adaptateur comprenant au moins un montant dont la longueur est réglable, une extrémité inférieure du montant étant propre à venir coopérer avec un longeron de la caisse de véhicule automobile, ce longeron étant situé sur la caisse en contrebas de la traverse,
  • une platine fixée à une extrémité supérieure du montant, sur laquelle peuvent venir s'appuyer les patins, la platine comprenant au moins une rainure oblongue,
  • chaque adaptateur comprenant deux galets comprenant un perçage, le perçage étant situé en regard de la rainure oblongue pratiquée dans la platine.
For this purpose, it is proposed, first, a handling system of an engine block, the handling system comprising a cross member, a support arm mounted on the cross member, and at least two pads mounted on the cross and positioned on both sides of the holding arm, this system comprising:
  • a pair of adapters, each adapter comprising at least one amount whose length is adjustable, a lower end of the upright being adapted to cooperate with a spar of the motor vehicle body, this spar being located on the body below the crosses,
  • a plate fixed to an upper end of the upright, on which the pads can come to rest, the plate comprising at least one oblong groove,
  • each adapter comprising two rollers comprising a bore, the bore being located opposite the oblong groove made in the plate.

Diverses caractéristiques supplémentaires peuvent, dans le cadre des revendications dépendantes, être prévues, seules ou en combinaison :

  • the lower tube of the left adapter comprises a threaded lower end and the lower tube of the right adapter comprises at an inferior end an indexing hole.

Il est proposé, en second lieu, un procédé de montage d'un système de manutention tel que précédemment décrit dans lequel celui-ci comprend les étapes :

  • de montage des adaptateurs sur une caisse de véhicule automobile,
  • de pose de la traverse de manutention sur les adaptateurs, les patins étant en appui sur la platine,
  • d'accroche du moteur, par exemple à l'aide de chaînes,
  • de retrait des fixations du moteur sur la caisse du véhicule.
It is proposed, secondly, a method of mounting a handling system as described above in which it comprises the steps:
  • mounting adapters on a motor vehicle body,
  • laying the handling crossbar on the adapters, the pads being supported on the plate,
  • attachment of the engine, for example using chains,
  • removal of engine fasteners on the vehicle body.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement et de manière concrète à la lecture de la description ci-après de modes de réalisation, laquelle est faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un véhicule automobile sur lequel est monté un système de manutention d'un bloc moteur ;
  • la figure 2 est une vue en perspective du système de manutention et du bloc moteur ;
  • la figure 3 est une vue éclatée en perspective de l'adaptateur droit ;
  • la figure 4 est une vue éclatée en perspective de l'adaptateur gauche ;
  • la figure 5 est une vue en perspective des tubes inférieurs des montants selon un deuxième mode de réalisation.
Other characteristics and advantages of the invention will appear more clearly and concretely on reading the following description of embodiments, which is made with reference to the appended drawings in which:
  • the figure 1 is a perspective view of a motor vehicle on which is mounted a handling system of an engine block;
  • the figure 2 is a perspective view of the handling system and the engine block;
  • the figure 3 is an exploded perspective view of the right adapter;
  • the figure 4 is an exploded perspective view of the left adapter;
  • the figure 5 is a perspective view of the lower tubes of the uprights according to a second embodiment.

Sur la figure 1, est représentée une caisse 1 d'un véhicule 2 automobile munie d'un système 3 de manutention d'un moteur 4, ce moteur 4 étant situé à l'avant du véhicule 2. On the figure 1 , there is shown a box 1 of a vehicle 2 having a motor vehicle handling system 3 4, the engine 4 being located at the front of the vehicle 2.

Le moteur 4 comprend une boîte de vitesses (non représentée), montée sur celui-ci. En pratique, et comme il l'a déjà été évoqué, la boîte de vitesses est difficilement accessible lorsque le moteur 4 est monté dans la caisse 1 du véhicule 2 automobile.The engine 4 comprises a gearbox (not shown) mounted thereon. In practice, and as has already been mentioned, the gearbox is difficult to access when the engine 4 is mounted in the body 1 of the vehicle 2 automobile.

Le système 3 de manutention comprend une traverse 5 longiligne munie de deux poutres 6 à section rectangulaire. Les poutres 6 sont rendues solidaires l'une de l'autre par une série de ponts 7 de fixation. Dans le mode de réalisation représenté sur les figures, les ponts 7 de fixation sont au nombre de quatre et présentent une forme cylindrique. Chaque extrémité 8 des ponts 7 de fixation loge dans une ouverture 9 circulaire pratiquée dans chaque poutre 6. Les poutres 6 sont espacées et positionnées l'une en regard de l'autre de sorte à définir un rail 10. The handling system 3 comprises an elongated cross member 5 provided with two beams 6 of rectangular section. The beams 6 are secured to one another by a series of bridges 7 fixing. In the embodiment shown in the figures, the fixing bridges 7 are four in number and have a cylindrical shape. Each end 8 of the fixing bridges 7 is housed in a circular opening 9 made in each beam 6. The beams 6 are spaced apart and positioned facing each other so as to define a rail 10.

Le système 3 de manutention comprend un bras 11 de maintien muni d'une manivelle 12 de réglage. Le bras 11 de maintien comprend à une extrémité 13 un embout 14 sur lequel sont montées deux portions de chaîne 15 métallique. Chaque chaîne 15 comprend une attache 16 destinée à accrocher une zone du moteur 4 prévue à cet effet.The handling system 3 comprises a holding arm 11 provided with a crank 12 for adjusting. The arm 11 holding one end 13 includes a tip 14 on which are mounted two chain portions 15 metal. Each chain 15 comprises a fastener 16 intended to hang an area of the engine 4 provided for this purpose.

La traverse 5 est équipée d'un patin 17, de part et d'autre du bras 11 de maintien. Chaque patin 17 comprend un support 18, une tige 19 et une manivelle 20 de blocage. La manivelle 20 de blocage permet de bloquer la translation du patin 17 sur le rail 10. La tige 19 est montée en liaison pivot sur le support 18. Ainsi, la tige 19 (et par conséquent la traverse 5) peut être inclinée par rapport au support 18. Autrement dit, il est possible d'incliner à souhait la tige 19 par rapport à la verticale. Un pion 21 de blocage permet de figer l'inclinaison.The crossbar 5 is equipped with a pad 17, on either side of the arm 11 holding. Each pad 17 comprises a support 18, a rod 19 and a blocking crank 20 . The blocking crank 20 makes it possible to block the translation of the pad 17 on the rail 10. The rod 19 is pivotally mounted on the support 18. Thus, the rod 19 (and consequently the crossbar 5 ) can be inclined with respect to 18. In other words, it is possible to incline at will the rod 19 relative to the vertical. A blocking pin 21 makes it possible to freeze the inclination.

Les patins 17 doivent être posés sur une surface sensiblement plane afin de conférer un maximum de sécurité. Cependant, les véhicules ne disposent pas forcément de zones planes au niveau de leur compartiment moteur.The pads 17 must be placed on a substantially flat surface in order to provide maximum safety. However, vehicles do not necessarily have flat areas in their engine compartment.

Le système 3 de manutention comprend un adaptateur 22 droit et un adaptateur 23 gauche respectivement représentés sur les figures 3 et 4. Les adaptateurs 22, 23 permettent aux patins 17 de prendre appui sur des zones planes. Les adaptateurs 22, 23 sont montés de façon à ce qu'ils soient solidaires de la caisse 1 du véhicule 2 automobile.The handling system 3 comprises a right adapter 22 and a left adapter 23 respectively shown on the figures 3 and 4 . The adapters 22, 23 allow the pads 17 to bear on flat areas. The adapters 22, 23 are mounted so that they are integral with the body 1 of the vehicle 2 automobile.

En l'espèce, la caisse 1 comprend de part et d'autre un longeron 24 droit et un longeron 25 gauche. Le longeron 25 gauche comprend deux orifices 26 dont une paroi interne est taraudée (taraudage non représenté). L'adaptateur 23 gauche comprend une platine 27 dont la section est en forme de U, une paire de galets 28 et deux montants 29 télescopiques.In this case, the body 1 comprises on each side a spar 24 right and a spar 25 left. The left spar 25 comprises two orifices 26 , an internal wall is threaded (tapping not shown). The adapter 23 left comprises a plate 27 whose section is U-shaped, a pair of rollers 28 and two uprights 29 telescopic.

Chaque montant 29 de l'adaptateur 23 gauche comprend un tube 30 inférieur et un tube 31 supérieur. Les tubes 30, 31 inférieur et supérieur sont munis d'une série de trous 32. Le tube 30 inférieur est monté de manière télescopique dans le tube 31 supérieur. La translation du tube 31 supérieur par rapport au tube 30 inférieur est bloquée grâce à un pion 33. Le blocage se fait en positionnant un trou 32 du tube 31 supérieur en regard d'un trou 32 du tube 30 inférieur puis en y insérant le pion 33. Une extrémité 34 inférieure du tube 30 inférieur est filetée (filetage non représenté sur les figures). Le tube 31 supérieur comprend à une extrémité 35 supérieure, une rondelle 36 de contact coopérant avec une surface 37 inférieure de la platine 27. La platine 27 comprend au moins une rainure 38 oblongue définissant un chemin. Dans le mode de réalisation représenté, la platine 27 comprend deux rainures 38 oblongues. Deux galets 28 dont la section est sensiblement trapézoïdale, sont montés coulissants sur la platine 27. Le mouvement des galets 28 est bloqué par une vis 39 de blocage vissée dans le galet 28 au travers d'un perçage 40 pratiqué dans celui-ci. La vis 39 de blocage passe à travers la rainure 38 et est finalement vissée dans un logement 41 du tube 31 supérieur.Each upright 29 of the left adapter 23 comprises a lower tube 30 and an upper tube 31 . The lower and upper tubes 30, 31 are provided with a series of holes 32. The lower tube 30 is telescopically mounted in the upper tube 31 . The translation of the upper tube 31 relative to the lower tube 30 is blocked by a pin 33. The blocking is done by positioning a hole 32 of the upper tube 31 next to a hole 32 of the lower tube 30 and inserting the pin 33. A lower end 34 of the lower tube 30 is threaded ( threading not shown in the figures). The upper tube 31 includes an upper end 35, a washer 36 cooperating with a contact surface 37 of the lower plate 27. The plate 27 comprises at least one elongated groove 38 defining a path. In the embodiment shown, the plate 27 comprises two oblong grooves 38 . Two rollers 28 whose section is substantially trapezoidal, are slidably mounted on the plate 27. The movement of the rollers 28 is blocked by a locking screw 39 screwed into the roller 28 through a bore 40 formed therein. The locking screw 39 passes through the groove 38 and is finally screwed into a housing 41 of the upper tube 31 .

Le montage de l'adaptateur 23 gauche se fait en fixant tout d'abord l'ensemble tube 30 inférieur et tube 31 supérieur (soit le montant 29) sur le longeron 25 gauche de la caisse 1 du véhicule 2 automobile. La fixation se fait en vissant chaque montant 29 dans un orifice 26. Cette opération terminée, la platine 27 est alors posée sur les rondelles 36 de contact, le perçage 40 des galets 28 et les rainures 38 des platines 27 étant positionnés en regard des logements 41. Les vis 39 de blocage sont alors vissées afin de figer l'adaptateur 23 gauche.The mounting of the adapter 23 left is done by first fixing the lower tube assembly 30 and upper tube 31 (the amount 29 ) on the left spar 25 of the body 1 of the vehicle 2 automobile. Fixing is done by screwing each upright 29 into a hole 26. This operation is completed, the plate 27 is then placed on the washers 36 of contact, the drilling 40 of the rollers 28 and the grooves 38 of the plates 27 being positioned opposite the housing 41. The locking screws 39 are then screwed in order to freeze the adapter 23 left.

L'adaptateur 22 droit, représenté sur la figure 3, est similaire en tout point à l'adaptateur 23 gauche à l'exception du tube 30 inférieur. Le tube 30 inférieur de l'adaptateur 22 droit comprend un trou 42 d'indexage destiné à coopérer avec un goujon 43 de la caisse 1 du véhicule 2 automobile.The adapter 22 right, shown on the figure 3 Is similar in every respect to the left adapter 23 with the exception of tube 30 below. The lower tube 30 of the adapter 22 includes a hole 42 right indexing intended to cooperate with a stud 43 of the body 1 of the vehicle 2 motor.

Le tube 30 inférieur peut prendre différentes formes afin de se conformer aux particularités de la caisse 1 du véhicule 2 automobile. Dans un second mode de réalisation représenté sur la figure 5, l'extrémité du tube 30 inférieur permet de se conformer à une paroi de carrosserie. Le tube 30 inférieur comprend des profilés 44 définissant des encoches 45 destinées à coopérer avec une paroi (non représentée) d'un longeron de la caisse 1. The lower tube 30 can take different forms in order to comply with the particularities of the body 1 of the automobile vehicle 2 . In a second embodiment shown on the figure 5 the end of the lower tube 30 makes it possible to conform to a body wall. The lower tube 30 comprises profiles 44 defining notches 45 for cooperating with a wall (not shown) of a spar of the body 1.

Le montage du système de manutention comprend avantageusement la mise en place des adaptateurs, le positionnement de la traverse 5, les patins 28 étant en appui et fixés sur les platines 27, l'élingage du moteur côté boite de vitesses, par exemple à l'aide d'une chaîne 15. Après dépose du support de boîte de vitesses, le moteur peut être descendu à la hauteur souhaitée, par desserrage de la manivelle 12. La dépose de la boîte de vitesses est alors effectuée.The mounting of the handling system advantageously comprises the installation of the adapters, the positioning of the crossbar 5, the pads 28 being supported and fixed on the plates 27, the slinging of the gearbox side motor, for example by means of a chain 15. After removal of the transmission support, the motor can be lowered to the desired height, by loosening the crank 12. The removal of the gearbox is then performed.

Ainsi, une fois le système 3 de manutention monté sur le véhicule 2, les fixations du moteur 4 sont retirées. Le moteur 4 a alors naturellement tendance à basculer vers l'avant ou vers l'arrière. Les chaînes 15 maintiennent le moteur 4, l'empêchant de buter sur la caisse 1 du véhicule 2. Afin de dégager la boîte de vitesses, la longueur des montants 29 de l'adaptateur 22 droit est raccourcie. Le bloc moteur, sous son propre poids, tangue du côté où la longueur des montants 29 est raccourcie, en l'occurrence du côté de l'adaptateur 22 droit. Une fois que l'accès à la boîte de vitesses est dégagé, le mécanicien peut la retirer en passant sous le véhicule et la remplacer.Thus, once the handling system 3 mounted on the vehicle 2, the fasteners of the engine 4 are removed. The engine 4 then naturally tends to tilt forwards or backwards. The chains 15 hold the motor 4, preventing it from abutting the body 1 of the vehicle 2. In order to clear the gearbox, the length of the uprights 29 of the adapter 22 right is shortened. The engine block, under its own weight, pitch on the side where the length of the uprights 29 is shortened, in this case on the side of the adapter 22 right. Once the access to the gearbox is cleared, the mechanic can remove it by going under the vehicle and replace it.

L'opération inverse est effectuée pour remonter le moteur 4. The reverse operation is performed to reassemble the motor 4.

Le système 3 de manutention offre sécurité et rapidité sur des véhicules et s'adapte à une large gamme de véhicules automobiles. Un seul opérateur est nécessaire pour maintenir le moteur.The 3 handling system offers safety and speed on vehicles and fits a wide range of motor vehicles. Only one operator is needed to maintain the engine.

Les points d'appui de la traverse sont placés à l'intérieur du compartiment moteur, au voisinage des points de fixation du groupe motopropulseur. Le système de manutention ne nécessite ainsi aucun appui sur le bord supérieur des ailes du véhicule. Le système de manutention peut être employé pour des véhicules comprenant des ailes en matériau polymère ou autre matériau pouvant présenter un matage lors de l'application d'une contrainte. Le système de manutention peut également être employé pour des véhicules comprenant des ailes dont le bord supérieur est fortement incliné par rapport à l'horizontale.The points of support of the crossbar are placed inside the engine compartment, in the vicinity of the attachment points of the powertrain. The handling system thus requires no support on the upper edge of the wings of the vehicle. The handling system can be used for vehicles comprising wings of polymer material or other material that may be matting during the application of stress. The handling system can also be used for vehicles comprising wings whose upper edge is strongly inclined relative to the horizontal.
