Description

ENSEMBLE DE MECANIQUE ADAPTATION.
Domaine Technique L'invention se rapporte à un élément de transmission d'un véhicule motorisé, notamment d'un véhicule comportant plusieurs essieux motorisés tel qu'un camion ou un véhicule de chantier. La ligne de transmission de tels véhicules comporte ainsi un ensemble de mécanique adaptation permettant de guider en rotation plusieurs arbres de transmission, mais également de répartir entre ces essieux le couple moteur aux roues.
L'invention vise plus particulièrement un ensemble de mécanique adaptation dont la maintenance de la pompe à huile notamment est facilitée par une architecture particulière.
Art antérieur De façon générale, les ensembles de mécanique adaptation équipant une ligne de transmission d'un véhicule motorisé, comportent un carter principal, également appelé support différentiel. A l'intérieur de ce carter, la lubrification des différents éléments s'effectue par un bain d'huile.
Autrement dit, c'est le mouvement des différents éléments tournant qui permet de déplacer l'huile se trouvant dans le fond du carter et de parvenir à lubrifier les différents paliers ou accouplements. Cependant, cette technique peut se révéler aléatoire, puisque rien ne garantit la présence en quantité suffisante de lubrifiant au niveau des différents paliers ou accouplements.
C'est pourquoi, on a déjà proposé d'intégrer une pompe à l'intérieur d'un ensemble de mécanique adaptation. Dans ce cas, la pompe est alors rapportée sur la face interne d'une plaque avant refermant l'ouverture d'accès du support différentiel. Cette architecture n'est pas très pratique car la mise en place de la pompe et son positionnement par rapport à son dispositif d'entraînement se fait "en aveugle", ce qui nécessite un ajustement très précis des différentes pièces, et peut fausser l'axe de l'arbre de la pompe.
Ainsi, le but de l'invention est de permettre une lubrification efficace et sûre des différents éléments à l'intérieur de l'ensemble de mécanique adaptation, d'une part, et de faciliter les opérations d'assemblage et de maintenance de cet ensemble, d'autre part.
Exposé de l'invention L'invention concerne donc un ensemble de mécanique adaptation équipant une ligne de transmission d'un véhicule motorisé, comportant des arbres guidés en rotation par différents paliers, des accouplements pour permettre l'entraînement des différents arbres, un support différentiel faisant office de carter, dans lequel circule de l'huile pour lubrifier les différents éléments roulants et accouplements. Le support différentiel comporte une ouverture avant, et une plaque avant permet de refermer cette ouverture avant du support différentiel.
Cet ensemble de mécanique adaptation se caractérise en ce que la plaque avant comporte un orifice débouchant sur la face externe de ladite plaque avant, et en ce qu'il comporte également une pompe rapportée au niveau de la face externe de ladite plaque avant et pénétrant au travers de l'orifice à l'intérieur de l'ensemble mécanique adaptation.
Autrement dit, l'ensemble de mécanique adaptation comporte un carter ouvert sur au moins une de ses faces. Cette configuration permet de rapporter, au niveau d'une plaque avant démontable du support différentiel, une pompe permettant de garantir une lubrification optimale des différents éléments, à l'intérieur de l'ensemble de mécanique adaptation.
En effet, la plaque avant comporte un orifice apte à recevoir une pompe en liaison avec l'intérieur de l'ensemble de mécanique adaptation. La solidarisation de la pompe avec la plaque avant se fait par l'extérieur, alors que la plaque avant est déjà mise en place sur le carter, au niveau de la face externe orientée vers l'extérieur de l'ensemble de mécanique adaptation.
Cette configuration permet ainsi le démontage simple et rapide de la pompe lorsqu'il est nécessaire de la changer, ou plus simplement de l'entretenir. Il n'est pas nécessaire de démonter la plaque avant pour accéder à la pompe à huile puisque qu'elle est insérée au niveau de l'orifice débouchant sur la face externe de la plaque avant.
Avantageusement, la plaque avant peut comporter un filtre à huile. Ainsi, lorsque la plaque avant est démontée du support différentiel, un filtre à huile reste solidaire de celle-ci et peut être changé si nécessaire.
En pratique, ce filtre à huile peut être démontable au niveau de la face externe de la plaque avant. Autrement dit, dans ce cas, il n'est pas nécessaire de démonter la plaque avant pour changer le filtre à huile. Cette configuration est en outre la plus intéressante, car elle permet de réduire considérablement les coûts générés par les opérations de maintenance.
Avantageusement, la pompe peut comporter un rotor et un stator intégrés au sein d'un logement. Dans ce cas, la pompe est formée par des éléments spécialement conçus pour cette application et n'est donc pas un élément du commerce rapporté dans l'ensemble de mécanique adaptation.
En pratique, la plaque peut comporter une zone d'aspiration dont le canal d'aspiration est orienté vers le bas et débouche à proximité du fond du support différentiel.
En d'autres termes, une canalisation permet d'aspirer l'huile tombant par gravité dans le fond du support différentiel. Cette canalisation débouche vers le bas et possède ainsi des orifices dont les axes de révolution sont sensiblement verticaux. De cette manière, l'aspiration se fait au plus près du fond du support différentiel de façon à ne pas aspirer de l'air lorsque, notamment, la vitesse de rotation des différents éléments est élevée.
En effet, lorsque la vitesse de rotation des différents éléments à l'intérieur de l'ensemble de mécanique adaptation est élevée, ces éléments brassent alors constamment l'huile, et par conséquent, seulement une faible quantité d'huile reste constamment au fond de l'ensemble de mécanique adaptation.
Description des figures La manière de réaliser l'invention ainsi que les avantages qui en découlent, ressortiront bien de la description du mode de réalisation qui suit, donné à titre indicatif et non limitatif, à l'appui des figures annexées dans lesquelles : - la figure 1 est une vue de dessous d'un véhicule motorisé comportant un ensemble de mécanique adaptation, conforme à l'invention ; - les figures 2 et 3 sont des vues en coupe partielle longitudinale de l'ensemble de mécanique adaptation, conforment à deux variantes de réalisation de l'invention ; Manière de décrire l'invention Comme déjà évoqué, l'invention concerne un ensemble de mécanique adaptation équipant une ligne de transmission d'un véhicule motorisé et comportant des arbres guidés en rotation par différents paliers, et des accouplements pour permettre l'entraînement des différents arbres.
Tel que représenté en figure 1, un véhicule motorisé (2) comporte un ensemble moteur (25) qui entraîne un arbre (5). Cet arbre (5) pénètre dans l'ensemble de mécanique adaptation (1) et entraîne notamment en sortie l'arbre (3) relié à l'essieu arrière. Selon les conditions de chargement et/ou de la route, il peut être nécessaire d'entraîner de façon synchrone ou non les arbres (3) et (4), et par conséquent de transmettre le même couple moteur aux deux essieux.
Tel que représenté à la figure 2, la plaque avant (8) est rapportée sur le support différentiel faisant office de carter, non représenté. Cette plaque avant présente un orifice (16) dans lequel une pompe (9) est rapportée. Cet orifice (16) débouche au niveau de la face externe (14) de la plaque avant (8), de façon à permettre la mise en place de la pompe (9) par l'orifice intérieur de l'ensemble de mécanique adaptation (1), et sans démonter la plaque avant (8).
Dans la forme illustrée, la pompe (9) utilisée est de type spécifique, puisqu'elle est dédiée à cette application et comporte un rotor (17) tournant vers l'intérieur d'un stator (18).
Un couvercle (23) sert à assurer la fermeture de la plaque avant et l'étanchéité au niveau de cette face externe (14).
Selon un mode de réalisation particulier, la plaque avant (8) peut également comporter un filtre à huile (13). Dans la représentation de la figure 2, ce filtre à huile (13) est également rapporté au niveau de la face externe (14) de la plaque avant (8). De cette manière, il peut être également changé facilement en déposant le couvercle (23).
La plaque avant (8) comporte de plus une zone d'aspiration (19) de l'huile et présente un certain nombre d'orifices (20) disposés au plus près du fond de l'ensemble de mécanique adaptation (1).
Tel que représenté à la figure 3, il est également possible de rapporter la pompe (9) à l'intérieur d'un chapeau (30). Dans ce cas, c'est le chapeau (30) qui est rapporté au niveau de la face externe (14) de la plaque avant (8).
Dans ce cas, le couvercle (23) garantit encore l'étanchéité au niveau de cette face externe (14).
Dans cet exemple de représentation, la pompe à huile (9) est un ensemble monobloc du commerce et, dans ce cas, un filtre à huile (13) est rapporté au niveau de la face interne (15) de la plaque avant (8).
Il ressort de ce qui précède qu'un ensemble de mécanique adaptation conforme à l'invention présente de multiples avantages, et notamment, il permet de faciliter les opérations de maintenance de la pompe.

ASSEMBLY OF MECHANICAL ADAPTATION.
TECHNICAL FIELD The invention relates to a transmission element of a motorized vehicle, in particular a vehicle comprising several motorized axles such as a truck or a construction site vehicle. The transmission line of such vehicles thus comprises a set of mechanical adaptation to guide multiple transmission shafts, but also to distribute between these axles the engine torque to the wheels.
The invention more particularly relates to a set of mechanical adaptation whose maintenance of the oil pump in particular is facilitated by a particular architecture.
PRIOR ART In general, the mechanical adaptation assemblies fitted to a transmission line of a motorized vehicle comprise a main casing, also called a differential support. Inside this housing, the lubrication of the various elements is carried out by an oil bath.
In other words, it is the movement of the various rotating elements that moves the oil in the bottom of the housing and to lubricate the various bearings or couplings. However, this technique can be random, since nothing guarantees the presence of sufficient lubricant at the different bearings or couplings.
Therefore, it has already been proposed to integrate a pump inside a set of mechanical adaptation. In this case, the pump is then attached to the inner face of a front plate closing the access opening of the differential support. This architecture is not very practical because the installation of the pump and its positioning relative to its drive device is "blind", which requires a very precise adjustment of the different parts, and can distort the shaft of the pump shaft.
Thus, the object of the invention is to allow efficient and safe lubrication of the various elements within the assembly of mechanical adaptation, on the one hand, and to facilitate the assembly and maintenance operations of this assembly , on the other hand.
SUMMARY OF THE INVENTION The invention therefore relates to a set of mechanical adaptation fitted to a transmission line of a motorized vehicle, comprising shafts guided in rotation by different bearings, couplings to enable the driving of different shafts, a differential support acting as a housing, in which oil circulates to lubricate the various rolling elements and couplings. The differential support comprises a front opening, and a front plate allows to close this front opening of the differential support.
This assembly of mechanical adaptation is characterized in that the front plate has an opening opening on the outer face of said front plate, and in that it also comprises a pump attached to the outer face of said front plate and penetrating the through the orifice inside the mechanical assembly adaptation.
In other words, the mechanical adaptation assembly comprises an open housing on at least one of its faces. This configuration allows to report, at a removable front plate of the differential support, a pump to ensure optimum lubrication of the various elements within the assembly of mechanical adaptation.
Indeed, the front plate has an orifice adapted to receive a pump in connection with the interior of the mechanical assembly adaptation. The securing of the pump with the front plate is from the outside, while the front plate is already in place on the housing, at the external face facing outward of the mechanical assembly adaptation.
This configuration thus allows the simple and rapid disassembly of the pump when it is necessary to change it, or simply to maintain it. It is not necessary to remove the front plate to access the oil pump as it is inserted at the opening opening on the outer face of the front plate.
Advantageously, the front plate may comprise an oil filter. Thus, when the front plate is disassembled from the differential support, an oil filter remains integral with it and can be changed if necessary.
In practice, this oil filter can be dismountable at the outer face of the front plate. In other words, in this case, it is not necessary to disassemble the front plate to change the oil filter. This configuration is also the most interesting because it significantly reduces the costs generated by maintenance operations.
Advantageously, the pump may comprise a rotor and a stator integrated within a housing. In this case, the pump is formed by elements specially designed for this application and is therefore not a commercial element reported in the assembly of mechanical adaptation.
In practice, the plate may comprise a suction zone whose suction channel is oriented downwards and opens near the bottom of the differential support.
In other words, a pipe makes it possible to suck the oil falling by gravity into the bottom of the differential support. This pipe opens downwards and thus has orifices whose axes of revolution are substantially vertical. In this way, the suction is closer to the bottom of the differential support so as not to suck air when, in particular, the speed of rotation of the various elements is high.
Indeed, when the rotational speed of the various elements inside the assembly of mechanical adaptation is high, these elements then constantly stir the oil, and therefore, only a small amount of oil remains constantly at the bottom of the set of mechanical adaptation.
DESCRIPTION OF THE FIGURES The manner of carrying out the invention as well as the advantages which result therefrom will emerge from the description of the embodiment which follows, given as an indication and not by way of limitation, in support of the appended figures in which: FIG. 1 is a view from below of a motorized vehicle comprising an adaptation mechanical assembly, according to the invention; - Figures 2 and 3 are longitudinal partial sectional views of the adaptation of the mechanical assembly, according to two embodiments of the invention; DESCRIPTION OF THE INVENTION As already mentioned, the invention relates to a mechanical adaptation assembly equipping a transmission line of a motorized vehicle and comprising shafts guided in rotation by different bearings, and couplings to enable the driving of different trees.
As shown in Figure 1, a motor vehicle (2) comprises a motor assembly (25) which drives a shaft (5). This shaft (5) enters the adaptation mechanical assembly (1) and in particular drives the output shaft (3) connected to the rear axle. Depending on the loading conditions and / or the road, it may be necessary to synchronously drive the shafts (3) and (4) synchronously or not, and therefore to transmit the same engine torque to the two axles.
As shown in Figure 2, the front plate (8) is attached to the differential support acting as a housing, not shown. This front plate has an orifice (16) in which a pump (9) is attached. This orifice (16) opens out at the external face (14) of the front plate (8), so as to allow the introduction of the pump (9) through the internal orifice of the adaptation mechanical assembly ( 1), and without removing the front plate (8).
In the illustrated form, the pump (9) used is of a specific type, since it is dedicated to this application and comprises a rotor (17) rotating inwardly of a stator (18).
A cover (23) serves to ensure the closure of the front plate and the seal at this outer face (14).
According to a particular embodiment, the front plate (8) may also include an oil filter (13). In the representation of Figure 2, the oil filter (13) is also reported at the outer face (14) of the front plate (8). In this way, it can also be easily changed by removing the lid (23).
The front plate (8) further comprises a suction zone (19) of the oil and has a number of orifices (20) disposed closest to the bottom of the adaptation mechanical assembly (1).
As shown in Figure 3, it is also possible to bring the pump (9) inside a cap (30). In this case, it is the cap (30) which is attached to the outer face (14) of the front plate (8).
In this case, the cover (23) still ensures sealing at this outer face (14).
In this example of representation, the oil pump (9) is a one-piece unit of the trade and, in this case, an oil filter (13) is attached at the inner face (15) of the front plate (8) .
It follows from the above that a set of mechanical adaptation according to the invention has multiple advantages, and in particular, it facilitates the maintenance of the pump.
