Abstract

The speed monitor is coupled to a generator driven by a fan belt, in order that the kinetic energy of the vehicle is only used for charging the battery (6) during deceleration. The monitor comprises an inertia switch with a mercury capsule associated with a relay for opening or closing the generator excitation or power circuit. Pref. the mercury capsule is fixed to a support to extend along the vehicle axis with the support mounted at a variable position to the horizontal. The movement of the mercury to the front of the capsule allows an internal contact to open and the relay excitation circuit is broken so that its contact closes to couple the alternator to the battery. The sensitivity to deceleration is dependent on the inclination angle. The monitor is designed for allowing max. engine performance and economy.

Description

Ze disperitif objeb de l'invention concerne les automatiemes liés aux les t@ars par inertie utilisés duns les systémes éconcmisenrs d'énergie. Ze disperitif objeb of the invention relates to the automiemes related to t @ ars by inertia used duns energy-saving systems.

Fen de dispsitifs sont astuellesent ocmmercialisés dans l'application pré @@entislle décrite - dispositif antematique de charge d'accmulateur électrique utilimant anigement l'émergie einétique du véhicule en décélération corne source de puissance et éliminant tout effet de charge sur le moteur durant une vitesse constante ou accélérée du sobile - et présentent souvent l'inconvénient d'une sdaptation diffisile ou d'une fabrication spécifique. Windows of devices are actualized in the pre @ @ entislle application described - antematic device for charging an electric accumulator using the einetic emulsion of the vehicle in deceleration as a source of power and eliminating any load effect on the engine during a speed constant or accelerated of the mobile - and often have the disadvantage of a difficult adaptation or of a specific manufacturing.

L'invention déorite pem@et d'adapter, sans ansune modification ni fahriontion spéciale, à tous véhioules metorisés ou tractés, un dispositif utilisant @omme moyen de lecture de variation de vitesse, la masse de meroure contenu dans une ampeule cylindrique, de type courant, controlant par un simple contact, à une de ses crtrémités, l'alimentation d'un relais classique fermant en ouvrant le fil du circuit de charge (+ ou - ) reliant le générateur à l'acoumulateur. The invention deorites pem @ and of adapting, without any modification or special operation, to all metorized or towed vehicles, a device using, as a means of reading the variation in speed, the mass of meroure contained in a cylindrical bulb, of the type current, controlling by a simple contact, at one of its crémémités, the supply of a classic relay closing by opening the wire of the load circuit (+ or -) connecting the generator to the accumulator.

L'empenle, réglahle horizontalement sur son support, est fixée dans l'axe de déplement du mobile.The empenle, horizontally adjustable on its support, is fixed in the axis of deployment of the mobile.

Dens une premiere vari@nte, la contact de l'ampoule est vers l'avant, et, sous l'action d'une décélération, le mercure se déplace à l'extrémité de l'ampoule - vars l'avant - assurent la fermeture de sen contact intérieur, done, l' alimentation de la bobine du relais - de type ouvert au repes - qui, en fermant sun contact, ferme le circuit de puissance du générateur, autorisant la charge de la battoire. L'entreinement energétique du reter du générateur électriqus est alors assaré par la masse da véhiolule décélérant, à travers, roues, hoie de vitesse, moteur et liaison mécanique de son rotor. Tonte decélération provoquere le monvement inverse du mercure - vers l'arriere - qui dégagera son contact, coupant l'alimentation du releis et arrétant la charge, libérant sinsi le moteur du vébicule de l'effet de charge électromeagnétique. In a first variation, the contact of the bulb is towards the front, and, under the action of a deceleration, the mercury moves at the end of the bulb - towards the front - ensuring the closing of its internal contact, done, the power supply of the relay coil - of the open-to-repes type - which, by closing its contact, closes the generator power circuit, authorizing the charging of the battery. The energetic drive of the reter of the electric generator is then offset by the mass of decelerating vehicle, through, wheels, speed hoe, motor and mechanical connection of its rotor. Mowing of deceleration will cause the reverse rise of the mercury - towards the rear - which will release its contact, cutting the power supply of the relay and stopping the charge, thus releasing the motor of the vehicle from the effect of electromagnetic charge.

Selon une deuxieme variante, et par mesure de sécurité, le circuit de charge se trouvertd femé avec la bobine du relais son alimentée - relaie de type fermé au repos -. Pour cela l'ampoule de mercure sera montée en sens inverse - son coutact ves l'arriere - toute décélération provoquera le déplacement du mercure - vers l'avant - qui n'assurera plus la fermeture de son contact intérieur, La bobine du relais de charge sera désercitée, le circuit de charge sera fermé et le générateur @ébitera dans la batterie. According to a second variant, and as a safety measure, the charging circuit will be closed with the coil of the relay energized - relay of the closed type at rest -. For this, the mercury bulb will be mounted in the opposite direction - its cost towards the rear - any deceleration will cause the mercury to move - towards the front - which will no longer ensure the closing of its internal contact, The coil of the relay charge will be de-energized, the charge circuit will be closed and the generator @ will flow into the battery.

Selon une troisiéme variantc, dans le cas d'intensité de charge importente, l'ampoule de meroure controlera toujours le relais de charge, mais, le contact la ce dernier outrira ou fermera le circuit d'excitation du générateur électrigue, travailant sur de faible courant. Dans ce cas il est , également, possible de faire passer le courant d'éxcitation directement dans l'ampoule de mercure es supprimant le relais de c@arge
Selon une quatrieme varainte et suivant l'importance méoanique du générateur éléctrique, l'ampoule de mercure conrolera, par l'intermédiaire du contact de relais de charge, l'entrainement mécanique du rotor du générateur en ouvrant ou fermant l'alimentation électrique d'un embrayage électromagnétique assurant la liaison du moteur du véhicule au générateur. Les cibles d'excitation et de puissance du générateur restant d'origine @ non controlés par des contacts.According to a third variantc, in the case of a significant charge intensity, the meroure bulb will always control the charge relay, but, the contact the latter will bypass or close the excitation circuit of the electrical generator, working on low current. In this case it is also possible to pass the excitation current directly into the mercury bulb, removing the relay from c @ arge
According to a fourth varainte and according to the mechanical importance of the electric generator, the mercury bulb will control, through the contact of load relay, the mechanical drive of the rotor of the generator by opening or closing the electric supply of an electromagnetic clutch ensuring the connection of the vehicle engine to the generator. The generator excitation and power targets remaining original @ not controlled by contacts.

Des épuipements complétent ces qudtrs (4) variantes. Epuipements complete these qudtrs (4) variants.

Un premier équipement comporte un contact manuel à deux positions, "nor- mal" et "économique", placé sur le tableau de bord et actionné par le conduo- Beur, Dans la position "normal", le contact élimine inaction de l'ampoule de mercure et la charge de la batterie est assurée, normalement, par le moteur du véhicule, suivant le monfage d'origine. Ceci apporte une sécurité an conducteur dans le cas oh le profil du déplacement de mobile ayant apports peu de décélé- ration, le voyant " défaut de charge " s'allume. La position "économique" de ce contact assure la suiveillance de la charge par le dispositif objet de 1' invention. A first equipment comprises a manual contact with two positions, "normal" and "economic", placed on the dashboard and actuated by the driver. In the "normal" position, the contact eliminates inaction of the bulb of mercury and the battery is charged, normally, by the vehicle engine, according to the original installation. This provides safety for the driver in the event that the profile of the movement of the mobile having brought about little deceleration, the "load fault" indicator lights up. The "economic" position of this contact ensures the monitoring of the load by the device which is the subject of the invention.

Un second équipement comprend un contact actionné par le pédale de freimv
Ce contact controle la bobine da relais de charge, autorisant la charge de la batterie, par le moteur en rotation, lorsque le conducteur freine, ou maintient par action sur la pédale, son vébicule à l'arrét. bans ce dernier cas, le mot- eur tourne an ralenti, consommant un minimum de carburant et peut donc êtra utilisé pour la charge de l'accumulateur.A second equipment includes a contact actuated by the freimv pedal
This contact controls the charge relay coil, authorizing the battery to be charged by the rotating motor when the driver brakes, or maintains his action when the pedal is depressed. In the latter case, the engine runs at idle, consuming a minimum of fuel and can therefore be used for charging the accumulator.

Un troisiémé équipament comporte un relais temporisé, de type courant - de 1' à 5' - dont la bobine est alimentée par le circuit du voyant " défaut de charge ", équipant, d'origine, tous les véhioules. Lorsque la lampe témoin s'ailume, la bobine de ce relais temporisé s'excite et son contact intervient dans le circuit de la bobine du relais de obarge, autorisant la charge par le moteur du véhicule durant la temporisation pré-établie. Cet équipement assure la fonction du contact manuel du tableau de bord, mais, automatiquement, libérant le conducteur d'une surveillance constante. A third equipment comprises a timed relay, of the current type - from 1 'to 5' - the coil of which is supplied by the circuit of the "load fault" warning light, fitted, as standard, to all vehicles. When the indicator light comes on, the coil of this time relay is energized and its contact intervenes in the circuit of the coil of the obarge relay, authorizing charging by the vehicle engine during the pre-established time delay. This equipment performs the function of manual contact of the dashboard, but, automatically, releasing the driver from constant monitoring.

Le dispositif, objet de l'invention, permet de charger l'accumuleteur d'un véhicule sans demender d'énergie à son moteur. La puissance active, utilisable pour l'entrainement du véhicule, se trouve augmentée, autorisant, pour un même deplacement du mobile, une économie d'énergie donc de carburant et assurant de meilleures accélérations. Ce dispositif présente les avantages de n'utiliser que des composants electrîques de grande diffusion, de type courant, de n'impo- ser aucune modification du véhicule ou d'un de ses éléments constituante, et, d'être adaptables eacilement, à tous les types de véhicules commercialisés actuellement. The device, object of the invention, makes it possible to charge the accumulator of a vehicle without requiring energy from its engine. The active power, which can be used for driving the vehicle, is increased, allowing, for the same displacement of the mobile, energy saving therefore of fuel and ensuring better accelerations. This device has the advantages of using only widely distributed electrical components of the current type, of imposing no modification of the vehicle or of any of its constituent elements, and of being adaptable to all. the types of vehicles currently marketed.

On ne s'éoarte nullement de l'esprit de l'invention en exploitant tout ou
partie des équipements pré-cités.We in no way depart from the spirit of the invention by exploiting all or
part of the aforementioned equipment.

Une légére augmentatin de la puissance éléctrique du générateur, ainsi
que de la capacité de la batterie, permet de libérer le moteur de de tous ses ac
cessoires, amélierant encore sa puissance utile, donc, l'éconcomie de carburant

mique - ventilateur, pompe à eau, pompe à essence, pompe à huile - d'une mani-
re individuelle, ou, de les entrainer à partir d'un moteur électrique commun.A slight increase in the electrical power of the generator, thus
that of the capacity of the battery, makes it possible to release the engine of all its ac
coppers, further improving its useful power, therefore, fuel economy
carried out. Just electrify each component, other than the ther motor

Le dessin annexé est une vue d'un montage réalisé sur un véhicule auto
mobile suivant la deuxiémé variante. Le contact du ralais de charge assure la
fermeture du cable de puissance reliant le générateur électrique à la batterie
lorsque la bobine de ce relais n'est pas alimentée. Ce montage comporte l'en-
semble des trois équipements.The accompanying drawing is a view of an assembly produced on a motor vehicle
mobile according to the second variant. The charge relay contact ensures
closing of the power cable connecting the electric generator to the battery
when the coil of this relay is not supplied. This assembly includes the
seems of the three equipments.

X X' est l'axe du véhicule. X' étant l'avant de l'automobile. Le cable de puissance (i) de l'alternateur (2) est branché sur une des bornes du contact du
relais (3). L'autre borne du contact - fermé au repos - est raccordé par un cable (4) à la borne isolée (5) de la batterie (6). XX 'is the center line of the vehicle. X 'being the front of the automobile. The alternator power cable (i) (2) is connected to one of the contact's terminals.

Lorsque le conducteur tourne le contact (a) de son véhicule, il ferme un

et, si le mercure est en position - vers l'arriere - son contact intérieur est
Cerné. La bobine du relais (3) est excitée, son contact est ouvert et la laison
entre l'alternateur (2) et la batterie (6) est coupée, pas d'effet de charge el-
ectromagnétique, le conducteur démarre son moteur sans faire travailler l'alter
natuer, donc, plus facilement
Le vehioule étant en mouvement, si une décélératin apparait, le mercure,
par inertie, so déplace vers l'avant de l'ampoule (14), son contact intérieur
est lors ouvert, le circuit unifilaire est coupé et la bobine du relais (3) n'
est plus éxcitée, son contact se ferme assurant la laison entre l'alternateur
(2) et la batterie (6). Il y a effet de charge supporté par l'énérgie cinétique
En augmentant l'angle (@@) il faut une décélération plus importante pour provoquer la charge. Inversement un angle plus petit rend le dispositif plus sensible. When the driver turns the ignition (a) of his vehicle, he closes a
circuit comprising - battery terminal (5), wire (7), closed contact (8) - which
is an original assembly, then, wire (9), contact input closed at rest (10),
brake pedal (11) not actuated, contact output (10), wire (12),
manual contact terminal (13) in "economic" position, therefore closed, contact output k

(2) and the battery (6). There is a load effect supported by kinetic energy
Increasing the angle (@@) requires a greater deceleration to cause the load. Conversely, a smaller angle makes the device more sensitive.

Si le conducteur afticnne le contacteur (13) et le positionne sur "normal", ii ouvre le contact, la bobine du relais (3) n'est plus excitée, autorisant la charge. Si le conducteur enfonce la pédale (11) il dégage le poussoir du contact

Ce contact ouvert coupe l'alimentation du relais (3) et autorise la charge.If the conductor turns on the contactor (13) and positions it on "normal", he opens the contact, the relay coil (3) is no longer energized, authorizing the load. If the driver depresses the pedal (11) he releases the button from the contact

cable (22) - original assembly -, the cable (23), connected to the cable (22), supplies the coil of the time delay relay (18), the output of the coil of this relay being connected to earth by the cable (24). The relay opens its contact which will remain open as long as the lamp is on, and, once the latter is extinguished, throughout the pre-established time delay. This open contact cuts the supply to the relay (3) and authorizes charging.

Toute vitesse constante ou accélérée maintien le mercure à l'arriere de l' ampoule (14) assurant la fermeture du contact intérieur, donc l'excitation du relais (3) et éliminant l'effet de charge électrique sur le moteur du véhicule. Any constant or accelerated speed keeps the mercury at the rear of the bulb (14) ensuring the closing of the internal contact, therefore the excitation of the relay (3) and eliminating the effect of electric charge on the engine of the vehicle.

Lorsque le conducteur coupe le contact (8), le relais (3) n'est plus alimenté et son contact ferme le circuit entre la batterie (6) et l'alternateur (2). When the driver cuts the ignition (8), the relay (3) is no longer supplied and its contact closes the circuit between the battery (6) and the alternator (2).

Ce dernier, à l'arret, est protégé des courants de l'accumulateur par les trois cathodes des branches positives du port triphasé monté d'origine.The latter, at standstill, is protected from the currents of the accumulator by the three cathodes of the positive branches of the three-phase port originally fitted.

L'emploi de composants non spécifiques, uniquement de série, autorise un bas prix de revient et apporte une garantie de fiabilité. Son application peut se réaliser, à la construction des véhicules - automobiles et camions - apportant encore une réduction du coût. A ce niveau, il serait possible d'électrifier tous les accessoires du vehicule de maniere > obtenir une puissance utile maximum du moteur, uniquement, pour la propulsion. L'invention peut s'adapter au remorques Xrao- tées de "camping", de camions ou aux wagons. Les ensembles tractés deviendraient autonome dans leur énergie électrique libérant la source motrice, et l'effet de charge assisterait le freinage mécanique.
