Description

La présente invention concerne un circuit de refroidissement par liquide d'un moteur thermique, notamment sur un véhicule automobile. De façon plus précise, elle concerne l'agencement de la boîte de dégazage dont est muni un tel circuit.The present invention relates to a liquid cooling circuit of a heat engine, in particular on a motor vehicle. More specifically, it relates to the arrangement of the degassing box with which such a circuit is provided.

Il est en effet nécessaire, sur un circuit de refroidissement par liquide d'un moteur thermique, de prévoir une boîte de dégazage destinée à recueillir les gaz qui peuvent apparaître en un point quelconque du circuit. Cette boîte doit être placée en partie haute, par rapport au reste du circuit, et elle comporte habituellement un bouchon fermant un orifice par lequel se fait le remplissage en liquide.It is indeed necessary, on a liquid cooling circuit of a heat engine, to provide a degassing box intended to collect the gases which may appear at any point of the circuit. This box must be placed in the upper part, in relation to the rest of the circuit, and it usually has a plug closing an orifice through which the liquid is filled.

Or, il peut arriver que, par manque de place, ledit orifice soit d'accès particulièrement difficile. Le brevet AT-A-340 206 décrit un agencement dans lequel un radiateur est porté par le châssis du véhicule, alors que la boîte de dégazage est montée sur la cabine, elle-même articulée sur le châssis. Pour permettre le déplacement relatif de la boîte par rapport au radiateur lors du basculement de la cabine, il est prévu un conduit souple ou articulé entre cette boîte et le radiateur. Cependant, dans cet agencement la boîte de dégazage est fixe par rapport à la partie adjacente du véhicule, en l'occurrence la cabine,' et son accessibilité n'est pas modifiée par le basculement de cette dernière.However, it may happen that, for lack of space, said orifice is particularly difficult to access. The patent AT-A-340 206 describes an arrangement in which a radiator is carried by the chassis of the vehicle, while the degassing box is mounted on the cabin, itself articulated on the chassis. To allow the relative movement of the box relative to the radiator during the tilting of the cabin, there is provided a flexible or articulated conduit between this box and the radiator. However, in this arrangement the degassing box is fixed relative to the adjacent part of the vehicle, in this case the cabin, and its accessibility is not modified by the tilting of the latter.

Le but de l'invention est de fournir un agencement simple procurant un bon accès à l'orifice de remplissage, même lorsque la boîte de dégazage est disposée en dessous et à une très faible distance d'une partie adjacente fixe.The object of the invention is to provide a simple arrangement providing good access to the filling orifice, even when the degassing box is placed below and at a very short distance from an adjacent fixed part.

Suivant l'invention, le circuit de refroidissement par liquide d'un moteur thermique d'un véhicule avec une cabine, comportant une boîte de dégazage munie d'un bouchon de remplissage et reliée audit circuit par au moins un conduit souple, est caractérisé en ce que la boîte de dégazage est montée sur un support articulé par rapport à la cabine du véhicule autour d'un axe fixe en vue d'autoriser un basculement limité de la boîte de dégazage pour faciliter l'accessibilité au bouchon de remplissage.According to the invention, the liquid cooling circuit of a heat engine of a vehicle with a cabin, comprising a degassing box provided with a filling plug and connected to said circuit by at least one flexible conduit, is characterized in that the degassing box is mounted on a support articulated with respect to the vehicle cabin around a fixed axis in order to allow a limited tilting of the degassing box to facilitate accessibility to the filling plug.

Un exemple de réalisation de l'invention fait l'objet de la description qui suit, en référence aux dessins joints dans lesquels :

  • la Figure 1 est une vue de face partielle d'un véhicule montrant un circuit de refroidissement agencé suivant l'invention ;
  • la Figure 2 est une coupe suivant la ligne 2-2 de la Fig. 1.
An exemplary embodiment of the invention is the subject of the description which follows, with reference to the accompanying drawings in which:
  • Figure 1 is a partial front view of a vehicle showing a cooling circuit arranged according to the invention;
  • Figure 2 is a section along line 2-2 of FIG. 1.

Dans l'exemple décrit, l'invention est appliquée à un véhicule utilitaire 1, à cabine avancée, dont on a notamment représenté le pare-brise 2, le tableau de bord 3, le volant de direction 4 et le capot 5 enveloppant le moteur.In the example described, the invention is applied to a utility vehicle 1, with an advanced cabin, of which the windshield 2, the dashboard 3, the steering wheel 4 and the hood 5 enveloping the engine have been shown. .

Ce moteur comporte, de façon classique, un circuit de refroidissement par liquide comportant, en particulier, un radiateur 6, une pompe de circulation 7 et une boîte de dégazage 8. Cette dernière est reliée, par deux conduits souples 9 et 10, d'une part au radiateur 6, d'autre part à la pompe 7, et elle comporte un bouchon de remplissage 11.This engine comprises, in a conventional manner, a liquid cooling circuit comprising, in particular, a radiator 6, a circulation pump 7 and a degassing box 8. The latter is connected, by two flexible conduits 9 and 10, of on the one hand to the radiator 6, on the other hand to the pump 7, and it includes a filling plug 11.

Comme il apparaît sur la Fig. 2, la boîte de dégazage est disposée entre un tablier 12 et une calandre 13, de telle sorte que le bouchon 11 se trouve au-dessous et à une courte distance d'une tôle de structure 14, sensiblement horizontale.As it appears in FIG. 2, the degassing box is arranged between an apron 12 and a grille 13, so that the plug 11 is located below and at a short distance from a sheet metal structure 14, substantially horizontal.

Suivant l'invention, la boîte de dégazage 8 est portée par un support basculant constitué par deux bras 15, 16 articulés sur deux chevilles 17, 18 portées par des tôles 19, 20 sensiblement verticales.According to the invention, the degassing box 8 is carried by a tilting support constituted by two arms 15, 16 articulated on two pegs 17, 18 carried by sheets 19, 20 substantially vertical.

Comme il est classique sur ce genre de véhicule, la calandre 13 est amovible et, lorsqu'elle est en place, la boîte de dégazage 8 est immobilisée par deux plots 21, 22 en matière élastique fixés respectivement sur le tablier 12 et sur la calandre 13.As is conventional on this type of vehicle, the grille 13 is removable and, when it is in place, the degassing box 8 is immobilized by two studs 21, 22 of elastic material fixed respectively on the apron 12 and on the grille 13.

Lorsque cette dernière est déposée, la boîte de dégazage 8 peut être basculée vers l'avant, ce mouvement de basculement étant limité par appui du bras 15 contre un bord plié 23 de la tôle 19. Dans la position basculée vers l'avant, comme représenté en trait mixte sur la Fig. 2, le bouchon 11 se trouve dégagé de la tôle horizontale 14 ce qui permet très facilement de faire le remplissage du circuit de refroidissement ou, simplement, de contrôler le niveau du liquide.When the latter is deposited, the degassing box 8 can be tilted forward, this tilting movement being limited by pressing the arm 15 against a folded edge 23 of the sheet 19. In the tilted forward position, as shown in phantom in FIG. 2, the plug 11 is released from the horizontal sheet 14 which makes it very easy to fill the cooling circuit or, simply, to control the level of the liquid.
