Abstract
Description
La présente invention consiste en l'utilisation de l'effet de poussée et de réaction de un ou plusieurs,engins ici dénommés réacteurs installés sur les véhicules automobiles pour aider et assister le freinage en cas de danger ou d'urgence et provoquer l'arrêt du véhicule avant l'accident.The present invention consists in the use of the thrust and reaction effect of one or more, machines here called reactors installed on motor vehicles to assist and assist braking in the event of danger or emergency and cause stopping of the vehicle before the accident.
Actuellement, tous les engins sur route ont comme seul moyen de freinage conduisant éventuellement à l'arrêt,l'action des freins à disques ou à patins,agissant sur les roues. Currently, all vehicles on the road have as their only means of braking possibly leading to a standstill, the action of disc or pad brakes, acting on the wheels.
Pour les poids lourds, il existe aussi les ralentisseurs électriques soulageant l'action des freins en descente mais ne pouvant arrêter complètement le véhicule.For heavy goods vehicles, there are also electric retarders which relieve the action of the brakes when going downhill but cannot stop the vehicle completely.
Le véhicule automobile ne peut donc s'arrêter que si l'adhérence au sol est satisfaisante.Même dans les conditions optimales,sol sec et propre avec surface dure,on admet que les distances d'arrêt sont importantes.On les estime généralement par le carré de la vitesse divisée par 10,la distance de freinage étant exprimée en mètre si la vitesse l'est KM/H. The motor vehicle can therefore only stop if the grip on the ground is satisfactory.Even under optimal conditions, dry and clean ground with hard surface, it is accepted that stopping distances are significant. They are generally estimated by the square of the speed divided by 10, the braking distance being expressed in meters if the speed is KM / H.
Par temps de pluie,feuilles mortes,verglas,neige,etc., l'adhérence devient faible, voire nulle et donc il devient difficile de s'arrêter, peut être impossible dans la distance voulue
Les systèmes existants évitant le blocage des roues s'ils optimalisent les conditions de freinage n'augmentent pas pour autant l'adhérence.au sol et la possibilité de freinage par conditions difficiles.In rainy weather, dead leaves, ice, snow, etc., grip becomes weak or even zero and therefore it becomes difficult to stop, may be impossible in the desired distance
Existing systems which avoid locking the wheels if they optimize the braking conditions do not increase grip on the ground and the possibility of braking in difficult conditions.
Le dispositif selon l'invention permet de palier à cette difficulté d'adhérence. I1 prévoit d'équiper les engins automobiles sur route de réacteurs placés sous la voiture ou dans la carrosserie qui, lors de leur mise en fonctionnement exerceraient un effet de poussée ou créeraient une force s'opposant à l'avancement du véhicule,effet apparenté au système de contrepoussée utilisé par les avions pour réduire leur vites après atterrissage.Un autre exemple de réalisation est le siège éjectable des avions de chasse
Ces réacteurs peuvent être de toutes natures,soit par exemple non limitatif: au gaz,liqrnjie ,poudre , soit à combustion ou explosion,etc;, choisis en fonction de leur efficacité et les modalités d'utilisation.The device according to the invention overcomes this difficulty of adhesion. I1 plans to equip motor vehicles on the road with reactors placed under the car or in the bodywork which, when put into operation would exert a thrust effect or create a force opposing the advancement of the vehicle, an effect similar to another push-up system used by airplanes to reduce their speed after landing. Another embodiment is the ejection seat of fighter planes
These reactors can be of all kinds, or for example not limiting: gas, liquid, powder, either combustion or explosion, etc ;, chosen according to their efficiency and the methods of use.
Ils pourraient être à effet progressif contrAlable ou a action définitive mis en oeuvre en cas de péril pour éviter un accident. La nature des dispositifs d'asservissement n'est pas définie ici et ne fait pas partie du présent brevet.Ils pourraient par exemple être actionnés par un bouton poussoir de sécurité, comme sur certaines machines outils, mû par le conducteur en cas de danger ou par un système électronique assurant une mise en marche dès qu'il y a blocage des roues, ou tout autre système. They could have a progressive, controllable effect or a definitive action implemented in the event of danger to avoid an accident. The nature of the servo devices is not defined here and does not form part of this patent. They could for example be actuated by a safety push button, as on certain machine tools, moved by the driver in the event of danger or by an electronic system ensuring start-up as soon as the wheels are locked, or any other system.
La force de poussée ou la puissance de réaction pourrait être telle qu'elle ralentisse fortement le véhicule ou qu'elle l'arrête en quelques mètres. The pushing force or the reaction power could be such that it greatly slows the vehicle down or stops it within a few meters.
Différentes sécurités seront a prévoir.Un cache pour protéger des intempéries pourra s'éjecter automatiquement; en cas d'incendie du véhicule, un dispositif a rejet latéral pourra être prévu,les berceaux de fixation comportant par exemple des fixations fusibles dès que la température atteint une certaine valeur, des ressorts rejetant les réacteurs. Different security will be expected. A cover to protect from the weather may eject automatically; in the event of a vehicle fire, a lateral discharge device may be provided, the fixing cradles comprising, for example, fusible attachments as soon as the temperature reaches a certain value, springs rejecting the reactors.
I1 devra être prévu que le dispositif ne puisse se mettre en route inopinément a l'arrêt,ou quand le moteur est en puissance,ou spontanément,après un accident,etc.. I1 must be provided that the device cannot start unexpectedly when stopped, or when the engine is running, or spontaneously, after an accident, etc.
La résistance mécanique des réacteurs sera facilement supérieure à la tôlerie légère des automobiles.Le danger sera très inférieur au transport dwdizaines de litres d'essence dans un réservoir en tôle mince. The mechanical strength of the reactors will be easily higher than that of light sheet metal in automobiles. The danger will be much lower when transporting dozens of liters of petrol in a thin sheet tank.
Le dispositif constitué par l'utilisation de réacteurs pour freiner l'automobile viendra rejoindre la panoplie des sécurités actuellement utilisées pour protéger les passagers: airbag-coussin d'air,ceinture de sécurité,ABS antiblocage des roues,etc.. The device constituted by the use of reactors to brake the automobile will join the panoply of safeties currently used to protect passengers: airbag-air cushion, seat belt, anti-lock ABS, etc.
I1 contribuera à sauver des milliers de vies humaines. It will help save thousands of human lives.
