Abstract

A starter device (1) has an electric starter motor (3) which may be of normal type and battery-fed. The starter motor (3) is provided with a toothed pinion (11), which in a known manner can be brought into meshing engagement with a gear rim (12) by a suitable control element, normally operated by an ignition key. The gear rim (12) was normally arranged on the flywheel (4) in such a way that the internal combustion engine could be started when starting with disengaged connection to the driven wheels. In the present design this gear rim (12) is located on the clutch disc (6) so that with the clutch (5) disengaged, that is with an interrupted connection between transmission shaft (8) and drive shaft end (2), the pinion (11) of the starter motor (3) engages with the gear rim (12). At the same time the starter motor (3) is energised so that it drives the clutch disc (6) and therefore the transmission shaft (8) by way of the pinion (11) and the gear rim (12). When the connecting transmission is now shifted, for example, into first gear, the vehicle can be moved by operating the switch element without having also to turn the combustion engine.

Description

La présente invention se rapporte à un véhicule comportant un moteur thermique de propulsion et un moteur électrique, ces moteurs pouvant être sélectivement accouplés aux roues du véhicule pour la propulsion de celui-ci, le cas échéant, en déconnectant le moteur thermique. The present invention relates to a vehicle comprising a thermal propulsion engine and an electric motor, these motors being able to be selectively coupled to the wheels of the vehicle for the propulsion thereof, if necessary, by disconnecting the thermal engine.

Comme l'on sait, la consommation en carburant des véhicules de tourisme classiques équipés d'un moteur a essence ou d'un moteur diesel est relativement satisfaisante sur les routes nationales et les autoroutes ; par contre, il n'en est pas de même en ville, où cette consommation est excessivement élevée. Ceci est d'autant plus regrettable que, en raison des faibles vitesses moyennes auquelles on roule en ville, les pertes effectives dues aux frottements de l'air et autres sont tres faibles. En effet, cette consommation élevée est due à des périodes prolongées de ralenti, au faible rendement des moteurs a combustion interne dans le domaine des charges partielles, ainsi qu'aux pertes résultant des démarrages et des freinages fréquents. As is known, the fuel consumption of conventional passenger vehicles equipped with a petrol or diesel engine is relatively satisfactory on national roads and motorways; on the other hand, it is not the same in the city, where this consumption is excessively high. This is all the more regrettable since, due to the low average speeds at which we drive in town, the actual losses due to air friction and the like are very low. Indeed, this high consumption is due to prolonged periods of idling, the low efficiency of internal combustion engines in the field of partial loads, as well as losses resulting from frequent starts and braking.

C'est la raison pour laquelle les clubs automobiles attirent continuellement l'attention sur le fait qu'il est possible d'économiser de l'essence en arrêtant le moteur dans les encombrements, aux feux de signalisation, etc. This is the reason why automobile clubs continually draw attention to the fact that it is possible to save fuel by stopping the engine in congestion, at traffic lights, etc.

Toutefois, ceci n'est pas pratique dans la réalité et pour cette raison, peu de conducteurs opèrent ainsi. De plus, chaque fois que la colonne de véhicules en attente avance de quelques mètres, le moteur doit è nouveau être relancé.However, this is not practical in reality and for this reason, few drivers operate this way. In addition, each time the waiting vehicle column advances a few meters, the engine must be restarted again.

Dans ces conditions, pour développer la puissance minimale nécessaire, on met en marche une machine de 50 kW dont la majeure partie de l'énergie est dissipée sous la forme de frottements internes, d'échauffement d'embrayage, etc.Under these conditions, in order to develop the minimum power required, a 50 kW machine is started up, most of the energy of which is dissipated in the form of internal friction, clutch heating, etc.

Il existe également un systeme de propulsion hybride pour véhicules en particulier, pour véhicules automobiles, comprenant un moteur thermique ou combustion et un moteur électrique qui peuvent être accouplés l'un à l'autre, la disposition étant telle que l'arbre du moteur électrique peut être relié directement, ou par l'intermédiaire d'un engrenage, aux organes de propulsion du véhicule, par exemple, aux roues tandis que le moteur thermique est relié par un accouplement débrayable, a l'arbre du moteur électrique. Dans ce système, le moteur électrique a non seulement pour fonction d'entraîner le véhicule, mais il peut également opérer comme une génératrice pour charger les batteries, c'est-à-dire, pour produire l'énergie électrique de démarrage. There is also a hybrid propulsion system for vehicles in particular, for motor vehicles, comprising a heat or combustion engine and an electric motor which can be coupled to each other, the arrangement being such that the shaft of the electric motor can be connected directly, or via a gear, to the vehicle's propulsion units, for example, to the wheels while the heat engine is connected by a disengageable coupling, to the shaft of the electric motor. In this system, the electric motor not only has the function of driving the vehicle, but it can also operate as a generator to charge the batteries, that is to say, to produce electric starting energy.

De tels systèmes de propulsion hydrides se composent généralement d'un moteur thermique ou a combustion et d'un moteur électrique qui peuvent être réliés alternativement, selon le mode de propulsion désiré du véhicule, par exemple, par l'intermédiaire d'un accouplement ou d'un embrayage et le cas échéant, d'un engrenage, aux organes de propulsion, par exemple, aux roues de celui-ci.  Such hybrid propulsion systems generally consist of a combustion or combustion engine and an electric motor which can be connected alternately, depending on the desired mode of propulsion of the vehicle, for example, by means of a coupling or a clutch and, if applicable, a gear, to the propulsion members, for example, to the wheels thereof.

I1 est par ailleurs, également connu d'accoupler les arbres des moteurs a combustion à un moteur électrique comportant un démarreur, auquel cas, celuici qui se présente sous la forme d'un moteur électrique pouvant faire fonction de moteur et de génératrice, a pour charge de lancer le moteur thermique et quand celui-ci est en marche, de jouer le rôle d'une génératrice rechargeant la batterie (voir DE-OS 25 01 386). It is furthermore also known to couple the shafts of combustion engines to an electric motor comprising a starter, in which case this which is in the form of an electric motor which can act as engine and generator, has for charge to start the engine and when it is running, to play the role of a generator recharging the battery (see DE-OS 25 01 386).

Le problème d'assurer la propulsion du-véhicule uniquement par un moteur électrique ayant les dimensions d'un démarreur alors que le moteur thermique est déconnecté, est nouveau en soi et un mode de réalisation judicieux, qui tient compte des considérations précédentes et qui les satisfait n'est pas encore connu. The problem of ensuring the propulsion of the vehicle only by an electric motor having the dimensions of a starter while the heat engine is disconnected, is new in itself and a judicious embodiment, which takes account of the preceding considerations and which satisfied is not yet known.

La présente invention apporte une solution a ce problème qui est carac térise en ce que le moteur électrique est conçu, de maniere connue, pour assurer exclusivement les fonctions de démarreur du moteur thermique et de génératrice électrique pour charger une batterie et en ce qlle des moyens d'accouplement connus sont prévus pour permettre, lorsque la liaison cinématique entre les roues et le moteur thermique est interrompue, établir une liaison effective entre le dispositif de démarrage et les roues motrices, en mettant ainsi le véhicule en mouvement. The present invention provides a solution to this problem which is characteristic in that the electric motor is designed, in known manner, to exclusively perform the functions of starter of the heat engine and of electric generator for charging a battery and in that of the means. Known coupling are provided to allow, when the kinematic connection between the wheels and the engine is interrupted, establish an effective connection between the starting device and the drive wheels, thereby setting the vehicle in motion.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée uniquement titre d'exemple non limitatif, en référence a la figure unique du dessin annexé qui est une coupe longitudinale à travers un dispositif d'accouplement de véhicule montrant schematiquement le démarreur et une partie du moteur thermique. Other characteristics and advantages of the invention will emerge from the description which follows, given solely by way of nonlimiting example, with reference to the single figure of the appended drawing which is a longitudinal section through a vehicle coupling device schematically showing the starter and part of the heat engine.

En se référant au dessin, on voit un dispositif de démarrage 1 qui comprend un moteur électrique 3 de construction normale et qui est alimenté par une batterie. Sur cette figura, on a également représenté, mais d'une manière très schématique, le moteur thermique, c'est-è-dire, le moteur combustion interne assurant la propulsion du véhicule dont l'arbre de sortie porte, à son extrémité 2, un volant 4, auquel fait suite un embrayage 5 comportant un disque d'embrayage 6. I1 s'agit, en l'occurrence, d'un dispositif d'embrayage universellement connu dans l'industrie automobile, dont la commande s'effectue au moyen d'une pédale, non représentée. A sa sortie, l'embrayage 5 comporte un arbre 8, auquel fait suite, de manière classique, une bote de vitesses (non représentée). Referring to the drawing, there is seen a starting device 1 which comprises an electric motor 3 of normal construction and which is powered by a battery. In this figure, there is also shown, but very schematically, the heat engine, that is to say, the internal combustion engine ensuring the propulsion of the vehicle whose output shaft carries, at its end 2 , a flywheel 4, followed by a clutch 5 comprising a clutch disc 6. It is, in this case, a clutch device universally known in the automotive industry, the control of which is carried out by means of a pedal, not shown. At its output, the clutch 5 comprises a shaft 8, which is followed, in a conventional manner, by a gearbox (not shown).

L'arbre 8 de la botte, qui porte le disque d'embrayage 6, est monté au moyen d'un palier antifriction 9 dans l'extrémité 2 de l'arbre du moteur.The shaft 8 of the boot, which carries the clutch disc 6, is mounted by means of an anti-friction bearing 9 in the end 2 of the engine shaft.

Le véhicule comporte également un moteur de démarrage 3 qui porte un pignon 11 qui, grâce à un organe de commande approprié, normalement actionné par une clé de contact, peut être amené ù engrener sur une couronne dentée 12.  The vehicle also includes a starting motor 3 which carries a pinion 11 which, by means of an appropriate control member, normally actuated by an ignition key, can be brought into gear on a ring gear 12.

Normalement, la couronne dentée 12 est solidaire du volant 4 de sorte que, au moment du démarrage, le moteur thermique peut ainsi etre lancé, étant bien entendu qp l'embrayage n'établit pas la liaison avec les roues motrices.Normally, the ring gear 12 is integral with the flywheel 4 so that, at the time of starting, the heat engine can thus be launched, it being understood that the clutch does not establish the connection with the driving wheels.

Par contre, dans le mode de réalisation selon l'invention, cette couronne dentée 12 est solidaire du disque d'embrayage 6, de sorte que quand l'embrayage 5 est débrayé, ctest-à-dire, quand la liaison cinématique entre l'arbre 8 de la botte et l'extrémité 2 de l'arbre de sortie du moteur thermique, le pignon il du démarreur 3 peut venir engrener sur la couronne dentée 12. Simultanément, le démarreur 3 est alimenté, de sorte que par l'intermédiaire du pignon 11 et de la couronne dentée 12, il entraine le disque d'embrayage 6 et partant, l'arbre 8 de la botte. Si, dans ces conditions, la boîte de vitesses est en première, il devient possible de faire avancer le véhicule sans que le moteur thermique soit obligé de tourner en même temps. By cons, in the embodiment according to the invention, this toothed ring 12 is integral with the clutch disc 6, so that when the clutch 5 is disengaged, that is to say, when the kinematic connection between the shaft 8 of the boot and the end 2 of the output shaft of the heat engine, the pinion il of the starter 3 can come to mesh on the ring gear 12. Simultaneously, the starter 3 is supplied, so that via the pinion 11 and the ring gear 12, it drives the clutch disc 6 and hence the shaft 8 of the boot. If, under these conditions, the gearbox is in first gear, it becomes possible to advance the vehicle without the engine being forced to run at the same time.

On voit donc que le démarreur qui existe dans chaque véhicule de tourisme est utilisé pour entraîner celui-ci directement, sans faire tourner pour autant son moteur thermique. il est ainsi possible de faire avancer un véhicule traditionnel, sans difficulté, à une vitesse de 10 km/h et de grimper des cotes ayant une pente d'environ 2 Z. Ainsi, même avec des batteries de série déchargées à 50 Z, il n'y a pas de problèmes pour propulser le véhicule électriquement pendant 15 à 30 minutes. It can therefore be seen that the starter which exists in each passenger vehicle is used to drive it directly, without however turning its internal combustion engine. it is thus possible to advance a traditional vehicle, without difficulty, at a speed of 10 km / h and to climb sides having a slope of approximately 2 Z. Thus, even with standard batteries discharged at 50 Z, it there is no problem to propel the vehicle electrically for 15 to 30 minutes.

Dans ces conditions, il est beaucoup plus souvent judicieux d'arreter le moteur thermique, de sorte que des demarrages inutiles, pour faire avancer le véhicule de quelques mètres peuvent etre évités. Ainsi, en plus d'une économie d'énergie, le conducteur ménage ses nerfs et l'environnement. Under these conditions, it is much more often advisable to stop the engine, so that unnecessary starts, to move the vehicle a few meters can be avoided. Thus, in addition to saving energy, the driver protects his nerves and the environment.

On remplace la couronne dentée du volant par une couronne dentée fixée sur le disque d'embrayage, éventuellement en Nylon. Pour lancer le moteur, il convient de se mettre au point mort. L'embrayage ne doit par être actionné. The toothed crown of the flywheel is replaced by a toothed crown fixed to the clutch disc, possibly made of Nylon. To start the engine, you must put in neutral. The clutch must not be actuated.

Pour pouvoir utiliser le démarreur pour la propulsion, il convient d'engager la première vitesse et d'appuyer sur la pédale d'embrayage. Dans ces conditions, le démarreur peut être actionne non seulement avec la clé d'allumage, mais également à l'aide d'un interrupteur supplémentaire placé à portée de la main.To be able to use the starter motor for propulsion, it is necessary to engage the first gear and to depress the clutch pedal. In these conditions, the starter can be operated not only with the ignition key, but also with the help of an additional switch placed within easy reach.

Pendant que le véhicule est entraîné par voie électrique, il est possible, en relâchant la pédale d'embrayage, de faire démarrer, d'une manière très élégante, le moteur thermique, à condition de ce mode de traction soit à nouveau possible.While the vehicle is being driven electrically, it is possible, by releasing the clutch pedal, to start the engine very elegantly, provided this mode of traction is again possible.

On voit donc que les modifications exigées par l'invention sont réduites à un minimum. Elles peuvent être réalisées soit directement au moment de la fabrication en série des véhicules, soit ultérieurement.  It can therefore be seen that the modifications required by the invention are reduced to a minimum. They can be performed either directly at the time of mass production of the vehicles, or later.

Ce mode de propulsion convient
- pour des convois ;
- pour quitter des aires dangereuses en cas de panne
- pour repartirdes feux de signalisation dont le vert ne dure que quelques instants
- pour quitter des postes d'essence , des parkings, etc
- pour sortir, la nuit, de zones habitées
- pour circuler dans des locaux fermés ; et
- comme remplacement pour de courts trajets tractés ;
- ainsi que dans les rues habitées.This propulsion mode is suitable
- for convoys;
- to leave dangerous areas in case of breakdown
- to start again the traffic lights whose green lasts only a few moments
- to leave petrol stations, parking lots, etc.
- to leave inhabited areas at night
- to circulate in closed premises; and

- as well as in the inhabited streets.

Bien que l'exemple de réalisation qui vient d'erre décrit paraîsse être le mode d'exécution pratique le plus naturel de l'invention, il est en principe, également possible de faire agir le démarreur, par exemple, au moyen d'un engrenage approprié, directement sur une ou plusieurs roues motrices, ou bien sur les roues qui ne sont pas motrices. En principe, il est également possible de prévoir un second démarreur, ayant seulement pour fonction d'assurer la propulsion lorsque le moteur principal est hors d'action. Enfin, il est également possible de faire agir le démarreur sur 'arbre d'entraînement des roues. La seule condition qui doit etre respectée dans un tel véhicule est de pouvoir separer le moteur thermique des roues devant être entraînées par le démarreur, ce qui peut être réalisé, par exemple, dans les véhicules normaux, en débrayant ou en intercalant une roue libre dans la transmission. Although the embodiment which has just been described appears to be the most natural practical embodiment of the invention, it is in principle also also possible to make the starter act, for example, by means of a appropriate gear, directly on one or more driving wheels, or on the wheels which are not driving. In principle, it is also possible to provide a second starter, which has the sole function of ensuring propulsion when the main engine is out of action. Finally, it is also possible to make the starter act on the wheel drive shaft. The only condition that must be met in such a vehicle is to be able to separate the heat engine from the wheels to be driven by the starter, which can be achieved, for example, in normal vehicles, by disengaging or inserting a free wheel in the transmission.

Les considérations qui précèdent sont tout aussi bien valables pour les vehicules comportant des boîtes de vitesses manuelles que pour ceux équipés de boites automatiques, par exemple, de boîtes hydrauliques, ou pour les véhicules ne comportant pas de bottes spéciales.  The above considerations are just as valid for vehicles with manual gearboxes as for those equipped with automatic gearboxes, for example, hydraulic gearboxes, or for vehicles without special boots.
