The hydraulic jack is fixed to a gear box by a cleat acting with a clutch mechanism (4).

Description

La présente invention caverne un dispositif réduisant la con-sommation deThe present invention caverns a device reducing the con-summation of

carburant d'un véhicule automobile lorsque le moteur n'est pas sollicité.  fuel from a motor vehicle when the engine is not in use.

Dans la conduite sur route,le pied est gardé sur la pédale d'accélération pour maintenir une vitesse moyenne,mais aussi pa-5 rce que cette pédale est disposée en manière de cale pied.  In driving on the road, the foot is kept on the accelerator pedal to maintain an average speed, but also pa-5 that pedal is arranged in a foot-hold way.

Le conducteur donne plus de gaz dans les montées,puis lève le pied, lorsque arrivé en haut il a besoin de moins de puissance.Dans les descentes il se laisse entrainer,réduit et accélère à nouveau lorsque la vitesse diminue. 10 En ville,généralement sur le plat,il cherche à maintenir une certaine vitesse qui le rapproche du véhicule précédent et l'oblige à lever le pied,freiner,puis relancerla voiture.  The driver gives more gas in the climbs, then raises the foot, when he arrives at the top he needs less power. In the descents he lets himself train, reduces and accelerates again when the speed decreases. 10 In the city, usually on the flat, he tries to maintain a certain speed that brings him closer to the previous vehicle and forces him to lift his foot, brake, then restart the car.

En dehors des courts instants de changements de rapports 15 le moteur, toujours embrayé,tourne à une vitesse peu éloignée de la vitesse de croisière,générant une consommation élevée pendant toute la conduite.  Apart from the brief moments of shifting the engine, still engaged, is running at a speed not far from the cruising speed, generating a high consumption during the entire driving.

Une partie importante de l'énergie produite est ainsi gaspillée dans le frein moteur et le freinage. 20 L'objet du présent brevet est de limiter la production d'énergie aux besoins stricts.  A large part of the energy produced is thus wasted in engine braking and braking. The object of this patent is to limit the production of energy to strict requirements.

A part les progrés réalisés dans le rendement des moteurs à combustion pour l'économie de carburant,dans le meilleur état actuel de la technique, c'est un ordinateur de bord qui 25 réduit l'injection de carburant lorsque les divers capteurs indiquent que le moteur est moins sollicité: Mais cette réduction est faible Le dispositif selon l'invention permet de réaliser notre objectif,en isolant le moteur de la masse roulante, lorsque 30 le conducteur lève le pied.Le moteur passe alors à la vitesse de ralenti avec une consommation réduite au tiers.  Apart from the progress made in the efficiency of combustion engines for fuel economy, in the best state of the art, it is an on-board computer which reduces fuel injection when the various sensors indicate that the This reduction is low. The device according to the invention makes it possible to achieve our objective by isolating the motor from the rolling mass when the driver lifts his foot. The motor then switches to idle speed with a reduced consumption to one-third.

800 tours au lieu de 2.400 sur le véhicule d'essai soit 66% d'économie.  800 laps instead of 2,400 on the test vehicle or 66% savings.

Cette actionest automatisée et s'effectue à l'insu du con- 35 ducteur,de façon que celui-ci puisse conduire d'emblée une voiture équipée, facilitant l'application du procédé dans un délai court à une partie importante du parc automobile.  This action is automated and is carried out without the knowledge of the driver, so that it can lead from the outset an equipped car, facilitating the application of the process in a short time to a significant portion of the car fleet.

La solution choisie pour s'adapter directement à la voiture standard actuelle,consiste à placer dans la pédale d'accélération un contacteur(1) pilotant électriquement un distributeur hydraulique 3 voies et 2 positions,qui actionne un vérin (2) agissant sur la fourchette d'embrayage. 5 Ce vérin est fixé au carter d'embrayage ou de boite de vitesse par des pattes ou équerres venues de fonderie,suivant que le vérin sera placé en amont ou en aval de la fourchette. Les pattes ou équerres servant au mécanisme de débrayage à pied pouvant également être mises à contribution. 10 Le vérin sera à simple ou double effet,suivant la disposition choisie et si les ressorts de l'embrayage suffisent au retour de la tige dans le laps de temps nécéssaire.  The solution chosen to adapt directly to the current standard car is to place in the accelerator pedal a contactor (1) electrically controlling a hydraulic distributor 3-way and 2 positions, which actuates a jack (2) acting on the fork clutch. This jack is attached to the clutch housing or gear box by brackets or brackets come from foundry, depending on whether the cylinder will be placed upstream or downstream of the fork. The brackets or brackets used for the foot release mechanism can also be used. The jack will be single or double acting, depending on the arrangement chosen and if the springs of the clutch suffice for the return of the rod in the necessary period of time.

La tige du vérin,guidée rigidement,sera reliée par une biélette articulée (3)en un point de la fourchette choisi 15 pour ne pas géner le fonctionnement du mécanisme d'embrayage à pied,de façon que le conducteur continue de se comporter comme à son habitude et effectue les changements de rapports aux moments appropriés.(4) Une centrale hydraulique à moyenne pression sera installée 20 spécialement,si on ne peut utiliser une centrale déjà existante,adaptée en conséquence.  The rod of the cylinder, guided rigidly, will be connected by a hinged link (3) at a point of the fork chosen 15 not to cause the operation of the foot clutch mechanism, so that the driver continues to behave as to it is customary to change gears at appropriate times. (4) A medium-pressure hydraulic power plant will be installed specially, if an already existing power plant can not be used, adapted accordingly.

Dès la mise en marche de la voiture,la pression hydraulique produira le débrayage,l'action du conducteur sur l'accélération opérant ensuite embrayages et.debrayages pendant la 25 conduite.  As soon as the car is started, the hydraulic pressure will produce the clutch, the action of the driver on the acceleration then operating clutches and clutches during driving.

D'autre solutions réalisant l'automatisme souhaité sont comprises dans le brevetjsoit électriques soit pneumatiques pour les véhicules qui en sont équipés;et il faut ajouterla solution mécanique ou le débrayage est obtenu par un ressort 30 antagoniste appliqué sur la fourchette,la pression du pied sur la pédale des gaz relachant la fourchette tout en donnant de la puissance au moteur.  Other solutions carrying out the desired automation are included in the patent, which is either electrical or pneumatic for the vehicles which are equipped with them, and the mechanical solution must be added or the clutch is obtained by an antagonistic spring applied to the fork, the pressure of the foot on the gas pedal releasing the fork while giving power to the engine.

Le système objet du brevet ne s'adresse ni au conducteur émérite ni à la voiture sportive.Son application est adaptée35 au conducteur mesuré et prudent utilisant un véhicule standard pour un usage quotidien, particulièremnt en ville.  The system covered by the patent is not intended for the skilled driver or the sports car. Its application is adapted35 to the measured and prudent driver using a standard vehicle for everyday use, especially in the city.

La conduite dans les moments ou le moteur est débrayé,interdit de l'automobile antique,ne pose pas de problème avec les voitures actuelles dont la directionrla suspension les cardans et les roues n'ont pas de jeu et ou la stabilité de marche très bon-ne sera assistée par ordinateur si nécessaire. 5 Le contacteur installé dans la pédale des gaz aura sa sensibilité reglée pour négliger le poids du pied posé et agir en fonction d'une pression effective,qui entrainera l'embrayage du moteur pour le debrayer à nouveau lorsque le pied se relève,.  Driving in moments when the engine is disengaged, banned from the antique car, does not pose a problem with current cars whose steering and suspension gimbals and wheels have no play and or the stability of walking very good -ne will be assisted by computer if necessary. 5 The switch installed in the throttle pedal will have its sensitivity adjusted to neglect the weight of the foot placed and act according to an effective pressure, which will cause the clutch of the engine to release it again when the foot is raised.

La solution ou le débrayage au repos serait obtenu par un 10 ressort antagoniste,l'embrayage restant assisté comme dans le dispositif décrit ci-dessus est inclue dans le brevet.Mais avec la possibilité de supprimer la pédale d'embrayage,reportée à à une période ultérieure ou les conducteurs seront prets à de nouvelles habitudes de conduite sur de nouveaux véhicules.  The solution or the disengagement at rest would be obtained by an opposing spring, the clutch remaining assisted as in the device described above is included in the patent. But with the possibility of removing the clutch pedal, transferred to a Later period or drivers will be ready for new driving habits on new vehicles.

15 Des essais effectués en manuel sur plusieurs milliers de kilomètres sur un utilitaire léger sorti en 2001,équipé d'un diésel common rail 1,9 60 kw circulant à vide,ont donné sur différents parcours des économies de 10 à 25% par rapport à la consommation prévue par le constructeur.Manual tests over several thousand kilometers on a light utility vehicle released in 2001, equipped with a 1.9 60 kw common rail diesel engine running unladen, have resulted in savings of between 10 and 25% over different routes. the consumption planned by the manufacturer.

20 Un conducteur ignorant,conduisant un véhicule équipé de notre dispositif ne depasserait sans doute pas 10% d'économie, mais un litre économisé chaque jour par un million de gens remplirait vite un tanker pétrolier,générant pour le pays des milliers de tonnes d'économies financières et envi- 25 ronnementales.20 An ignorant driver, driving a vehicle equipped with our device would probably not exceed 10% economy, but a liter saved every day by a million people would quickly fill a tanker tanker, generating for the country thousands of tons of financial and environmental savings.
