bISPOSITIE bE PROTECTION DE RAMPE D'ALIMENTATIONbISPOSITIE bE POWER SUPPLY PROTECTION
bE CARBURANT.FUEL.
La présente invention concerne la protection des rampes d'alimentation de carburant de moteur à combustion interne contre les chocs, notamment en cas de déformation frontale du bloc moteur. The present invention relates to the protection of the fuel supply ramps of an internal combustion engine against shocks, especially in the event of frontal deformation of the engine block.
Sur de nombreux moteurs, la bride de liaison du répartiteur d'admission est en matière plastique. Une solution simple pour assurer ta protection des rampes d'alimentation de carburant, consiste à remplacer la bride en plastique par une bride en aluminium, de manière à disposer d'une cale de protection métallique. Toutefois, si la cale est rigide, elle transmet intégralement les chocs, sans possibilité d'amortissement par déformation. On many engines, the connecting flange of the intake manifold is made of plastic. A simple solution for protecting the fuel supply ramps is to replace the plastic flange with an aluminum flange so that a metal shim is available. However, if the shim is rigid, it transmits the shocks in full, without the possibility of depreciation by deformation.
bans les mêmes conditions, tout écran rigide fixé sur le moteur indépendamment de la rampe d'admission, présente le même inconvénient de transmettre à celle-ci l'essentiel du choc reçu. be plus, un tel écran est généralement difficile à implanter dans le compartiment moteur, pour des raisons d'encombrement. under the same conditions, any rigid screen attached to the engine independently of the intake manifold has the same drawback of transmitting to it the bulk of the shock received. be more, such a screen is generally difficult to implement in the engine compartment, for reasons of space.
Dans la mesure où les rampes d'alimentation sont habituellement en matière plastique, et où les risques de déclenchement d'incendie en cas de rupture sont réels, les systèmes de protection qui ne sont pas capables d'amortir les chocs, ne sont pas satisfaisants. As the supply ramps are usually made of plastic, and where the risk of fire triggering in case of breakage is real, protection systems that are not capable of absorbing shocks are unsatisfactory. .
La présente invention vise à assurer dans de meilleures conditions, la protection d'une rampe d'alimentation de carburant en cas de choc frontal du véhicule. The present invention aims to provide in better conditions, the protection of a fuel supply ramp in the event of a frontal impact of the vehicle.
bans ce but, elle propose un dispositif de protection composé d'un ensemble déformable par écrasement fixé sur la culasse, et d'une béquille de renforcement fixée d'une part sur cet ensemble, et d'autre part sur le carter cylindre. for this purpose, it proposes a protection device consisting of a crushable deformable assembly fixed on the cylinder head, and a reinforcement stand fixed on the one hand on this assembly, and on the other hand on the cylinder block.
De préférence, ce dispositif comprend au moins une colonnette s'écrasant progressivement en cas de choc et orientée dans la direction des vis de fixation du répartiteur d'admission sur la culasse. Preferably, this device comprises at least one small column crashing in the event of impact and oriented in the direction of the fixing screws of the intake manifold on the cylinder head.
D'autres caractéristiques et avantages de l'invention ressortiront clairement à la lecture de la description suivante d'un mode de réalisation non limitatif de celle-ci, en se reportant aux dessins annexés, sur lesquels - la figure 1 est une vue d'ensemble du moteur équipé du protecteur, - la figure 2 est une vue du côté du dispositif proposé, et - la figure 3 est une vue de dessus du même dispositif Sur les figures, on voit le corps du dispositif de protection proposé, constitué d'une tôle de protection 1, de colonnettes 2 et d'une béquille 4. La tôle 1 est reliée aux colonnettes par des renforts 3, apparaissant sur les figures 1 et 2, qui montrent également la béquille 4 et l'emplacement de ces différents éléments par rapport à la culasse 7, au carter-cylindre 8, au répartiteur d'admission 9, et ä la rampe d'alimentation en carburant 11. Other features and advantages of the invention will become clear from reading the following description of a non-limiting embodiment thereof, with reference to the accompanying drawings, in which - Figure 1 is a view of assembly of the motor equipped with the protector, - figure 2 is a view of the side of the proposed device, and - figure 3 is a top view of the same device. In the figures, we see the body of the proposed protection device, consisting of a protective sheet 1, columns 2 and a stand 4. The sheet 1 is connected to the posts by reinforcements 3, shown in Figures 1 and 2, which also show the stand 4 and the location of these different elements relative to the cylinder head 7, the cylinder block 8, the intake manifold 9, and the fuel supply ramp 11.
Le dispositif de protection proposé se compose en effet d'un ensemble déformable par écrasement fixé sur la culasse 7, et de la béquille de renforcement 4, fixée d'une part sur cet ensemble, et d'autre part sur le carter cylindre 8. The proposed protection device consists in fact of a crushable deformable assembly fixed on the yoke 7, and of the reinforcement stand 4, fixed on the one hand on this assembly, and on the other hand on the cylinder block 8.
L'ensemble déformabte est constitué par la tôle 1 et par des colonnettes 2. La tôle 1 est vissée de préférence sur la culasse 7 par les vis 5, et la béquille 4 est vissée de préférence sur le carter cylindre 8 et sur la tôle 1, par les vis 6. Les colonnettes 2, ici au nombre de quatre, sont rapportées sur la tôle 1, de préférence par soudage. Leur fonction est de s'écraser progressivement en cas de choc. Elles sont orientées dans la direction des vis de fixation 10 du répartiteur d'admission 9 sur la culasse 7. La tôle 1 est disposée en avant de la rampe d'alimentation 11, de manière à étre protégée par l'ensemble du dispositif en cas de choc frontal. The deformable assembly is constituted by the sheet 1 and by columns 2. The sheet 1 is screwed preferably on the yoke 7 by the screws 5, and the stand 4 is screwed preferably on the cylinder block 8 and on the sheet 1 by the screws 6. The columns 2, here four in number, are attached to the sheet 1, preferably by welding. Their function is to crash gradually in case of shock. They are oriented in the direction of the fastening screws 10 of the intake distributor 9 on the cylinder head 7. The plate 1 is disposed in front of the feed ramp 11, so as to be protected by the entire device in case frontal shock.
La rigidité des colonnettes 2 est renforcée par les renforts 4, vissés â la fois sur chaque colonnette 2, et sur la tôle 1. Sur les figures, on compte trois vis de fixation 5 de la tôle 1 sur la culasse 7, mais ce nombre n'est pas limitatif. The rigidity of the columns 2 is reinforced by the reinforcements 4, screwed both on each small column 2, and on the sheet 1. In the figures, there are three fixing screws 5 of the sheet 1 on the cylinder head 7, but this number is not limiting.
Enfin, un léger jeu doit être prévu au montage, entre l'extrémité des colonnettes 2 et les têtes de vis de fixation 10 du répartiteur 9, pour éviter que le dispositif soit hyperstatique. Finally, a slight clearance must be provided for mounting, between the end of the columns 2 and the fixing screw heads 10 of the distributor 9, to prevent the device is hyperstatic.
En conclusion, le dispositif de protection proposé par l'invention, qui encapsule la rampe d'alimentation de carburant sur la face d'admission du moteur, permet la protection de cette rampe lors d'une déformation frontale du compartiment moteur, par écrasement progressif des colonnettes. Cet écrasement est maîtrisé par le choix de dimensions optimales pour les colonnettes, qui peut être effectué grâce â des calculs de préconisation. In conclusion, the protection device proposed by the invention, which encapsulates the fuel supply ramp on the intake face of the engine, allows the protection of this ramp during a frontal deformation of the engine compartment, by progressive crushing. Columns. This crushing is controlled by the choice of optimal dimensions for the balusters, which can be carried out by means of recommendation calculations.
