Abstract
Description
Véhicule industriel comportant un moteur insonorisé et deux radiateurs placés de chaque côté du moteur.Industrial vehicle with a soundproof engine and two radiators placed on each side of the engine.
La présente invention concerne un véhicule industriel lourd tel qu'un camion par exemple. The present invention relates to a heavy industrial vehicle such as a truck for example.
Ces véhicules comportent généralement deux longerons, un moteur installé entre ces deux longerons, et un radiateur de refroidissement placé devant le moteur, entre les deux longerons. These vehicles generally comprise two beams, an engine installed between these two beams, and a cooling radiator placed in front of the engine, between the two beams.
Comme le radiateur est situé dans l'axe du moteur, le débit d'air sortant du radiateur traverse le compartiment moteur, et il est donc impossible de placer autour de ce moteur un caisson d'insonorisation. As the radiator is located in the axis of the engine, the air flow leaving the radiator crosses the engine compartment, and it is therefore impossible to place around this engine a soundproofing box.
En effet le compartiment moteur doit être laissé libre afin de permettre l'évacuation de l'air chaud sortant du radiateur.Indeed the engine compartment must be left free to allow the evacuation of the hot air leaving the radiator.
Si l'on veut néanmoins insonoriser le moteur à l'aide d'un caisson il faut que l'air sortant du radiateur soit dévié sur le côté du moteur, mais ceci diminue les performances du dispositif de refroidissement du moteur. If, however, the engine is to be soundproofed using a box, the air leaving the radiator must be diverted to the side of the engine, but this reduces the performance of the engine cooling device.
La présente invention a pour but d'améliorer les performances du dispositif de refroidissement du moteur tout en utilisant un caisson d'insonorisation. The present invention aims to improve the performance of the engine cooling device while using a soundproofing box.
Ce but est atteint en utilisant deux radiateurs placés chacun à l'extérieur d'un longeron. This object is achieved by using two radiators, each placed outside a beam.
La présente invention a pour objet un véhicule industriel comportant, en partie avant, deux longerons réunis par des traverses, un groupe moto-propulseur disposé entre les longerons, et un dispositif de refroidissement du groupe moto-propulseur comportant au moins un échangeur air-eau. The subject of the present invention is an industrial vehicle comprising, in the front part, two longitudinal members joined by crosspieces, a propulsion unit arranged between the longitudinal members, and a device for cooling the propellant unit comprising at least one air-water exchanger .
Selon la présente invention, ce véhicule comporte un caisson d'insonorisation enveloppant le groupe moto-propulseur, le dispositif de refroidissement comportant, à l'extérieur de chaque longeron, un échangeur air-eau. According to the present invention, this vehicle comprises a soundproofing box enveloping the power train, the cooling device comprising, outside each beam, an air-water exchanger.
Selon une caractéristique particulière de l'invention, chaque échangeur air-eau est installé approximativement verticalement et perpendiculairement au plan de symétrie du véhicule. According to a particular characteristic of the invention, each air-water exchanger is installed approximately vertically and perpendicular to the plane of symmetry of the vehicle.
Ce véhicule comporte en outre, dans le prolongement de chaque échangeur air-eau une paroi enveloppant la partie supérieure de la roue du véhicule et permettant, à l'air rejeté par l'échangeur, de s'échapper dans l'atmosphère principalement en arrière de la roue. This vehicle further comprises, in the extension of each air-water exchanger, a wall enveloping the upper part of the wheel of the vehicle and allowing, to the air discharged by the exchanger, to escape into the atmosphere mainly behind of the wheel.
De manière préférentielle chaque échangeur air-eau est muni d'un ventilateur entraîné par un moteur, et chaque échangeur peut recevoir en amont un autre échangeur. Preferably, each air-water exchanger is provided with a fan driven by a motor, and each exchanger can receive another exchanger upstream.
Selon une autre caractéristique de l'invention, ce véhicule comporte une structure secondaire qui participe à la raideur de la structure porteuse principale constituée des longerons et des traverses, le caisson d'insonorisation étant alors constitué de parois fixées sur la structure secondaire. According to another characteristic of the invention, this vehicle comprises a secondary structure which participates in the stiffness of the main supporting structure consisting of the side members and crosspieces, the soundproofing box then being made up of walls fixed to the secondary structure.
I1 est décrit ci-après à titre d'exemple et en référence aux dessins annexés, un véhicule selon l'invention. I1 is described below by way of example and with reference to the accompanying drawings, a vehicle according to the invention.
La figure 1 est une vue shématique qùi montre, en perspective, l'avant d'un véhicule selon l'invention, sans la structure porteuse secondaire et sans la cabine de pilotage. Figure 1 is a schematic view which shows, in perspective, the front of a vehicle according to the invention, without the secondary support structure and without the cockpit.
La figure 2 est une vue de côté d'un véhicule montrant un seul échangeur air-eau, un côté de la structure porteuse secondaire et la cabine de pilotage installée sur cette structure. Figure 2 is a side view of a vehicle showing a single air-water exchanger, one side of the secondary support structure and the cockpit installed on this structure.
Dans la figure 1 sont représentés seulement un caisson d'insonorisation 1 enveloppant le moteur, les deux longerons 2 et les traverses 3 qui constituent la structure porteuse principale du véhicule, ainsi que deux échangeurs air-eau 4,5 assurant le refroidissement du moteur, et enfin les deux roues avant 6. In FIG. 1 are shown only a soundproofing box 1 enveloping the engine, the two side members 2 and the cross members 3 which constitute the main load-bearing structure of the vehicle, as well as two air-water exchangers 4.5 ensuring the cooling of the engine, and finally the two front wheels 6.
Les deux échangeurs air-eau 4,5, appelés communément radiateurs, sont placés chacun d'un côté du caisson 1, à l'extérieur d'un longeron 2. Chaque radiateur est placé verticaIement et perpendiculairement au longeron 2, devant une roue 6. The two air-water exchangers 4,5, commonly called radiators, are each placed on one side of the box 1, outside a spar 2. Each radiator is placed vertically and perpendicularly to the spar 2, in front of a wheel 6 .
La figure 2 montre un véhicule dans lequel les radiateurs sont placés dans la même situation que dans la figure 1, mais ils sont dans ce cas légèrement inclinés. Seul le radiateur 4 est représenté dans cette figure 2. Chaque radiateur est muni d'un ventilateur 7 entraîné par un moteur 8 par exemple électrique. Figure 2 shows a vehicle in which the radiators are placed in the same situation as in Figure 1, but in this case they are slightly inclined. Only the radiator 4 is shown in this figure 2. Each radiator is provided with a fan 7 driven by a motor 8, for example electric.
Chaque radiateur peut recevoir en superposition un ou plusieurs échangeurs tels que par exemple un échangeur air-air de refroidissement d'air de suralimentation, un condenseur de climatisation, un ou des radiateurs air-huile de refroidissement de boites de vitesse ou autres organes. Ces échangeurs supplémentaires sont généralement situés en amont de l'écoulement d'air par rapport au radiateur air-eau, et fixés directement sur celui-ci. Each radiator can receive one or more exchangers in superposition, such as for example an air-air exchanger for supercharging air cooling, an air conditioning condenser, one or more air-oil radiators for cooling gearboxes or other members. These additional exchangers are generally located upstream of the air flow with respect to the air-water radiator, and fixed directly to the latter.
ll est avantageux de disposer les divers échangeurs de la façon suivante : d'un côté superposer un radiateur air-eau et l'échangeur airair de suralimentation, de l'autre superposer au second radiateur le condenseur de climatisation et éventuellement d'autres radiateurs d'huile par exemple. Une commande séparée de chacun des moteurs d'entraînement 8 des ventilateurs 7 permet alors d'avoir deux niveaux possibles de ventilation forcée, en fonction de la température d'eau, ce qui permet d'obtenir des gains de bruit et de rendement, et d'accroître le refroidissement de l'air de suralimentation, en fonction de son niveau de température, sans être obligé de créer une ventilation forcée de l'ensemble des radiateurs air-eau. Ceci permet d'améliorer les conditions de fonctiorinement du moteur, en utilisant un faisceau d'échangeur de suralimentation de plus petite dimension. It is advantageous to arrange the various exchangers as follows: on one side superimpose an air-water radiator and the charge air exchanger, on the other superimpose on the second radiator the air conditioning condenser and possibly other radiators d oil for example. A separate control of each of the drive motors 8 of the fans 7 then makes it possible to have two possible levels of forced ventilation, as a function of the water temperature, which allows noise and efficiency gains to be obtained, and increase the cooling of the charge air, depending on its temperature level, without having to create forced ventilation of all the air-water radiators. This makes it possible to improve the operating conditions of the engine, by using a smaller charge exchanger harness.
Sur cette figure 2, le véhicule comporte en outre une paroi 9 enveloppant la partie supérieure de la roue, et un bouclier avant 10. Ce bouclier avant 10 comporte des entrées d'air 11, et la paroi 9 comporte, à l'arrière de la roue, des sorties d'air 12. Entre le bouclier 10 et la paroi 9 sont également prévues des sorties d'air 13. In this FIG. 2, the vehicle further comprises a wall 9 enveloping the upper part of the wheel, and a front shield 10. This front shield 10 comprises air inlets 11, and the wall 9 comprises, at the rear of the wheel, air outlets 12. Between the shield 10 and the wall 9 are also provided air outlets 13.
L'air participant au refroidissement du radiateur 4, traverse d'abord les entrées d'air 11, le radiateur 4, puis l'espace laissé libre au- dessus de la paroi 9, la majorité de l'air sortant du radiateur étant évacuée dans l'atmosphère par les sorties 12, le reste étant évacué par les sorties 13. Chaque radiateur 4,5 est ainsi traversé par un flux d'air capté sur la face avant du véhicule (récupération optimale de la pression dynamique), puis rejeté vers les passages de roue. The air participating in the cooling of the radiator 4, first passes through the air inlets 11, the radiator 4, then the space left free above the wall 9, the majority of the air leaving the radiator being evacuated in the atmosphere by the outlets 12, the rest being discharged through the outlets 13. Each radiator 4,5 is thus traversed by a flow of air captured on the front face of the vehicle (optimal recovery of dynamic pressure), then rejected to the wheel arches.
La figure 2 montre aussi une structure porteuse secondaire 14 constituée de différentes poutres latérales 15, 16, 17, 18 toutes solidarisées à la structure porteuse principale. Bien entendu la structure secondaire comporte de l'autre coté du moteur les mêmes poutres latérales que les poutres 15, 16, 17 et 18, ainsi que des poutres transversales (non représentées) reliant les deux sous-ensembles de poutres latérales. FIG. 2 also shows a secondary support structure 14 made up of different lateral beams 15, 16, 17, 18 all secured to the main support structure. Of course the secondary structure comprises on the other side of the engine the same lateral beams as the beams 15, 16, 17 and 18, as well as transverse beams (not shown) connecting the two sub-assemblies of lateral beams.
Cette structure porteuse secondaire 14, qui enveloppe le moteur, permet de réaliser un caisson d'insonorisation sous forme de plaques ou parois fixées sur les poutres latérales et transversales. This secondary supporting structure 14, which envelops the motor, makes it possible to produce a soundproofing box in the form of plates or walls fixed to the lateral and transverse beams.
Ces parois peuvent en outre comporter des ouvertures qui correspondent à des flux d'air de ventilation minimale pour certains accessoires du moteur, tel que, par exemple, l'alternateur ou le turbocompresseur. Ces ouvertures de ventilation peuvent d'ailleurs être traitées acoustiquement. Ces ouvertures peuvent être constituées de volets thermostatiques permettant d'ajuster l'écoulement d'air de ventilation, en fonction de la température relevée à l'intérieur du caisson. These walls may also have openings which correspond to minimum ventilation air flows for certain engine accessories, such as, for example, the alternator or the turbocharger. These ventilation openings can also be treated acoustically. These openings can be made up of thermostatic shutters making it possible to adjust the flow of ventilation air, as a function of the temperature recorded inside the box.
La structure porteuse secondaire 4 sert en outre de support à une cabine 9. Cette cabine est reliée à l'avant de la structure porteuse secondaire 4, par l'intermédiaire d'un bras articulé 20 et d'une liaison élastique 2, et à l'arrière de la structure porteuse secondaire, par l'intermédiaire d'une seule liaison élastique 2. The secondary support structure 4 also serves as a support for a cabin 9. This cabin is connected to the front of the secondary support structure 4, by means of an articulated arm 20 and an elastic connection 2, and to the rear of the secondary support structure, via a single elastic link 2.
Ce véhicule selon l'invention permet ainsi un refroidissement optimal du moteur et de ses accessoires, une bonne insonorisation de ce compartiment moteur, et enfin une utilisation optimale d'une structure porteuse secondaire qui porte, non seulement le caisson d'insonorisation, mais aussi la cabine. This vehicle according to the invention thus allows optimal cooling of the engine and its accessories, good soundproofing of this engine compartment, and finally optimal use of a secondary support structure which carries, not only the soundproofing box, but also the cabin.
