En revanche, un dispositif de ce genre n'est pas utilisé pour entraîner d'autres organes auxiliaires d'un moteur à combustion interne ou d'un véhicule, tels qu'une dynamo, un alternateur, un ventilateur de refroi¬ dissement du moteur, une pompe de circulation de l'eau de refroidissement,On the other hand, a device of this kind is not used to drive other auxiliary members of an internal combustion engine or of a vehicle, such as a dynamo, an alternator, a fan for cooling the engine. , a cooling water circulation pump,
20 ou tout autre organe dont le fonctionnement est lié à celui du moteur. En effet, la vitesse de rotation des turbines actionnées par les gaz d'échappement, telles qu'elles sont réalisées usuellement, est beaucoup plus grande que la vitesse admissible pour ces organes auxiliaires. A titre d'exemple, une turbine de modèle courant fonctionne avantageusement20 or any other member whose operation is linked to that of the engine. In fact, the speed of rotation of the turbines actuated by the exhaust gases, as they are usually produced, is much greater than the admissible speed for these auxiliary members. For example, a current model turbine works advantageously
25 a des régimes pouvant atteindre jusqu'à 100.000 tours/minute, tandis qu'un alternateur de modèle courant ne doit pas dépasser un régime d'environ 10.000 tours/minute. On a par conséquent assuré jusqu'à maintenant l'entraînement des organes auxiliaires à partir de l'arbre du vilebrequin du moteur, dont le régime de rotation est du même ordre 30 de grandeur que celui des organes auxiliaires.25 has speeds of up to 100,000 revolutions / minute, while a current model alternator should not exceed a speed of around 10,000 revolutions / minute. Consequently, the auxiliary members have therefore been driven until now from the crankshaft of the engine, the rotation speed of which is of the same order of magnitude as that of the auxiliary members.
Toutefois, il serait avantageux de prélever sur les gaz d'échappement, la puissance nécessaire pour ces organes auxiliaires, de manière à récupérer une part de l'énergie résiduelle de ces gaz au lieu de laHowever, it would be advantageous to take from the exhaust gases, the power necessary for these auxiliary members, so as to recover a part of the residual energy of these gases instead of the

The present invention proposes to fill this gap by providing a device for recovering part of the energy not used by the motor, to drive one or more organs.
39 auxiliaires du moteur. Dans ce but, le dispositif selon l' invention est caractérisé en ce qu' il comprend des moyens de transmission pour connecter la turbine à au moins un des organes auxiliaires, et pour entraîner cet organe en rotation avec elle .39 engine auxiliaries. For this purpose, the device according to the invention is characterized in that it comprises transmission means for connecting the turbine to at least one of the auxiliary members, and for driving this member in rotation with it.
Dans une forme de réalisation préférée , les moyens de transmission comportent un réducteur de vitesse . Ainsi , il est possible de réaliser le dispositif avec des turbines usuelles, telles. que celles des turbo¬ compresseurs actuels, et avec des organes auxiliaires courants, dont la vitesse de rotation est nettement plus petite que celle de la turbine . Le réducteur de vitesse peut être constitué par une boîte à engrenages dont le rapport de réduction est compris entre 5 et 20, mais de préfé¬ rence voisin de 10, de manière à permettre l' utilisation de régimes de rotation avantageux autant sur la turbine que sur les organes auxiliaires de modèle courant.In a preferred embodiment, the transmission means comprise a speed reducer. Thus, it is possible to produce the device with conventional turbines, such. than those of current turbo¬ compressors, and with current auxiliary members, the rotational speed of which is significantly lower than that of the turbine. The speed reducer can be constituted by a gearbox whose reduction ratio is between 5 and 20, but preferably close to 10, so as to allow the use of advantageous rotation regimes as much on the turbine as on auxiliary devices of current model.
Dans le but de réduire les dimensions et les masses des engrenages, le rapport de réduction de la boîte à engrenages peut être limité à une valeur comprise entre 2 et 5, et de préférence voisin de 3 , en cûmplé- tant le réducteur de vitesse par une transmission constituée de deux poulies reliées par une courroie , le rapport de réduction de la trans¬ mission par courroie étant compris entre 2 et 6, et de préférence voisin de 4. Il est possible d ' obtenir ainsi un rapport de réduction global compris entre 5 et 20, par exemple voisin de 10 à 12, en fonction des caractéristiques de vitesse des divers organes auxiliaires à utiliser.In order to reduce the dimensions and the masses of the gears, the reduction ratio of the gearbox can be limited to a value between 2 and 5, and preferably close to 3, by adding the speed reducer by a transmission consisting of two pulleys connected by a belt, the reduction ratio of the belt transmission being between 2 and 6, and preferably close to 4. It is thus possible to obtain an overall reduction ratio between 5 and 20, for example close to 10 to 12, depending on the speed characteristics of the various auxiliary members to be used.
Le réducteur de vitesse peut également être constitué seulement par une transmission à courroie telle que décrite ci -dessus, la plus petite des poulies étant montée sur le même axe que la turbine . Dans ce cas , le support de réduction global est plus faible que ci-dessus , par exemple inférieur à 10, ce qui peut nécessiter d ' installer un dispositif supplé¬ mentaire pour limiter la vitesse de rotation de la turbine , de manière à éviter un régime trop élevé des organes auxiliaires et de la transmis¬ sion par courroie . Par exemple , la tubulure des gaz d' échappement peut être agencée pour ne conduire à la turbine qu' une fraction du débit des gaz, et peut comporter un organe de réglage du débit ou de la pression des gaz admis à traverser la turbine .The speed reducer can also be constituted only by a belt transmission as described above, the smallest of the pulleys being mounted on the same axis as the turbine. In this case, the overall reduction support is weaker than above, for example less than 10, which may require installing an additional device to limit the speed of rotation of the turbine, so as to avoid too high speed of the auxiliary members and of the belt transmission. For example, the exhaust gas pipe can be arranged to lead to the turbine only a fraction of the gas flow rate, and may include a member for adjusting the flow rate or the pressure of the gases admitted to pass through the turbine.
OM Le dispositif tel que décrit est utilisable pour entraîner un ou plusieurs des organes auxiliaires d' un moteur, tels qu' on les ren¬ contre en particulier sur des véhicules automobiles. La réalisation préférée consiste à entraîner une génératrice de courant électrique , par exemple un alternateur, qui peut délivrer l ' énergie électrique nécessaire à d ' autres organes auxiliaires du moteur ou du véhicule .OM The device as described can be used to drive one or more of the auxiliary members of an engine, such as are used in particular on motor vehicles. The preferred embodiment consists in driving an electric current generator, for example an alternator, which can deliver the electrical energy necessary for other auxiliary components of the engine or of the vehicle.
Parmi les autres organes susceptibles d' être actionnés par le disposi¬ tif proposé, il y a lieu de mentionner un ventilateur de refroidissement du moteur, ainsi qu ' une pompe de circulation d 'eau de refroidissement. Entraînés par les gaz d ' échappement, ces organes auront l ' avantage de fonctionner à régime élevé quand le débit des gaz est grand , c' est-à- dire quand le moteur fonctionne à puissance élevée , et assureront par conséquent un refroidissement dont la puissance est à tout moment en relation avec la puissance du moteur.Among the other members capable of being actuated by the proposed device, mention should be made of an engine cooling fan, as well as a cooling water circulation pump. Driven by the exhaust gases, these members will have the advantage of operating at high speed when the gas flow is large, that is to say when the engine is running at high power, and will therefore provide cooling whose power is always related to the power of the engine.
Il importe de relever que les dispositifs tels que proposés peuvent être agencés pour entraîner soit un seul organe auxiliaire , soit plusieurs de ces organes séparés ou combinés entre eux . Par exemple , une trans- mission à courroie peut entraîner plusieurs poulies montées sur des organes séparés.It is important to note that the devices as proposed can be arranged to drive either a single auxiliary member, or several of these members separated or combined with one another. For example, a belt drive can drive multiple pulleys mounted on separate members.
La présente invention sera mieux comprise en référence à un exemple de réalisation et au dessin annexé illustrant sché atiquement une vue partiellement coupée d ' une forme d 'exécution préférée du dispositif .The present invention will be better understood with reference to an exemplary embodiment and to the appended drawing illustrating in a dry view a partially cut view of a preferred embodiment of the device.
En référence à la figure , le dispositif se compose essentiellement d 'une turbine 10 d' un réducteur à engrenages 11, et d ' un réducteur à pouliesReferring to the figure, the device essentially consists of a turbine 10 of a gear reducer 11, and of a pulley reducer
12 dont l' axe de sortie 13 est connecté à un organe auxiliaire 14, tel qUe par exemple un alternateur, d ' un moteur à combustion interne 15. La turbine 10 est une turbine du type de celle utilisée couramment sur les moteurs à turbo compresseur. Elle est montée sur la tubulure d ' échappe¬ ment 16 du moteur 15, et rejette les gaz d' échappement par une tubulure axiale 17. L' arbre de sortie 18 de la turbine 10, porté par un palier 19 monté dans un boîtier 20, constitue l 'entrée du réducteur à engrenages 11. Dans l'exemple décrit, ce réducteur se compose d ' un petit pignon 21 monté sur l' arbre 18, et d ' un grand pignon 22 dont l' axe 23 porte la petite poulie 24 du réducteur à poulies 12. La poulie 24 est reliée à une poulie 25 montée sur l' axe 13 et couplée à la poulie 24 par une courroie trapézoïdale 26.12 whose output shaft 13 is connected to auxiliary member 14, as Ue q p ar example an alternator, an internal combustion engine 15. The turbine 10 is a turbine of the type commonly used on engines turbo compressor. It is mounted on the exhaust pipe 16 of the engine 15, and rejects the exhaust gases through an axial pipe 17. The output shaft 18 of the turbine 10, carried by a bearing 19 mounted in a housing 20 , constitutes the input of the gear reducer 11. In the example described, this reducer consists of a small pinion 21 mounted on the shaft 18, and of a large pinion 22 whose axis 23 carries the small pulley 24 of the pulley reducer 12. The pulley 24 is connected to a pulley 25 mounted on the axis 13 and coupled to the pulley 24 by a trapezoidal belt 26.
Grâce au double étage réducteur, il est possible de raccorder une turbine du type connu tournant à des vitesse de l' ordre de 100 000 tours par minute, à un alternateur traditionnel pouvant tourner à des vitesses maximales de l' ordre de 10 000 tours/minute . Le double étage réducteur permet d' obtenir une réduction de l' ordre de 10. Toutefois il est bien entendu que cette réduction n'est nécessaire que dans la mesure ob l' on souhaite adapter les vitesses d 'un alternateur connu à celle d'une tur¬ bine traditionnelle. IL serait possible d 'envisager la réalisation de turbines tournant à des vitesses inférieures à 10 000 tours/minute, e t des alternateurs dont la vitesse maximale d' utilisation soit supérieure à 10 000 tours/minute . Ceci permettrait éventuellement d ' interposer un réducteur dont le facteur de réduction est inférieur à 10, voire de supprimer totalement le réducteur.Thanks to the double reduction stage, it is possible to connect a turbine of the known type rotating at speeds of the order of 100,000 revolutions per minute, to a traditional alternator which can rotate at maximum speeds of the order of 10,000 revolutions /. minute. The double reduction stage makes it possible to obtain a reduction of the order of 10. However, it is understood that this reduction is only necessary insofar as one wishes to adapt the speeds of a known alternator to that of a traditional tur¬ bine. It would be possible to envisage the production of turbines rotating at speeds lower than 10 000 revolutions / minute, and alternators whose maximum speed of use is higher than 10 000 revolutions / minute. This would eventually make it possible to interpose a reducer whose reduction factor is less than 10, or even to completely eliminate the reducer.
En outre dans l 'exemple représenté, le réducteur comporte deux étages dont l' un est un réducteur à engrenages et l' autre un réducteur à poulies . II serait envisageable de réaliser un réducteur à engrenages à un ou plusieurs étages de réduction ,ou un réducteur à poulies et courroie à 1 ou plusieurs étages de réduction. Enfin le réducteur pourrait être monté dans un boîtier solidaire de la carcasse de la turbine .Furthermore, in the example shown, the reducer has two stages, one of which is a gear reducer and the other of which is a pulley reducer. It would be conceivable to produce a gear reducer with one or more reduction stages, or a pulley and belt reducer with 1 or more reduction stages. Finally, the reducer could be mounted in a housing secured to the casing of the turbine.
Bien que dans l'exemple représenté, l' organe auxiliaire est constitué par un alternateur, cet organe auxiliaire pourrait être constitué par tout autre élément tel que le ventilateur de refroidissement, la pompe à eau, un compresseur d' asservissement etc. En outre le dispositif selon l' invention pourrait être combiné directement avec un système turbo¬ compresseur de type connu et monté en série sur certains véhicules .Although in the example shown, the auxiliary member is constituted by an alternator, this auxiliary member could be constituted by any other element such as the cooling fan, the water pump, a servo compressor etc. In addition, the device according to the invention could be combined directly with a turbo ¬ compressor system of known type and fitted in series on certain vehicles.
