Abstract

La présente invention concerne un système roulant tirant son énergie d’un volant d’inertie. Cette énergie est transmise aux roues par un mécanisme différentiel dont l’un des planétaires est relié aux roues et l’autre à un frein à disque. Lorsque le frein est activé, l’énergie du volant est transmise aux roues.The present invention relates to a rolling system drawing its energy from a flywheel. This energy is transmitted to the wheels by a differential mechanism, one of the sun gears of which is connected to the wheels and the other to a disc brake. When the brake is activated, energy from the steering wheel is transmitted to the wheels.

Description

Système roulant accélérateurAccelerator Rolling System

Les moteurs, en général thermiques ou électriques, des véhicules terrestres ou aériens, sont dimensionnés pour assurer la propulsion en régime de croisière, mais aussi pour convenir aux accélérations tant de mise en vitesse initiale qu'au cours des parcours. Cette dernière demande conduit à installer des puissances importantes. Ainsi, pour les voitures de tourisme, les puissances des moteurs sont en gros deux fois plus grandes que celles nécessaires à la seule vitesse de croisière, et à des montées de 5 %. Pour les avions, à propulsion partiellement ou totalement électrique, les puissances installées des moteurs sont nécessairement faibles ; de ce fait, les distances de décollage sont très grandes et très pénalisantes. La présente invention a pour but de remédier à ces inconvénients en installant un système dédié aux accélérations, puisant son énergie dans un volant d'inertie, transmettant cette énergie (cinétique) aux roues des véhicules, ou du train d'atterrissage quand il s'agit d'un avion. Le principe du système roulant selon la présente invention est analogue au mécanisme différentiel du brevet 12 01001 déposé le 04/04/2012 concernant la commande mécanique à volant d'inertie, pour disjoncteurs de coupure électrique. Dans ce brevet l'énergie tirée du volant d'inertie est destinée à provoquer en un temps très bref, moins de 2/100 de seconde, un déplacement d'une dizaine de centimètres de la tige de contact, en développant une puissance importante.The motors, generally thermal or electric, of land or air vehicles, are sized to provide propulsion at cruising speed, but also to be suitable for accelerations both for initial speed setting and during journeys. This last request leads to the installation of high powers. Thus, for passenger cars, the engine powers are roughly twice as large as those required at cruising speed alone, and at 5% climbs. For planes, with partially or totally electric propulsion, the installed powers of the engines are necessarily low; as a result, the take-off distances are very long and very penalizing. The object of the present invention is to remedy these drawbacks by installing a system dedicated to accelerations, drawing its energy from a flywheel, transmitting this energy (kinetic) to the wheels of the vehicles, or of the landing gear when it is acts of an airplane. The principle of the rolling system according to the present invention is analogous to the differential mechanism of the patent 12 01001 filed on 04/04/2012 concerning the mechanical flywheel control, for electrical cut-off circuit breakers. In this patent the energy drawn from the flywheel is intended to cause in a very short time, less than 2/100 of a second, a displacement of about ten centimeters of the contact rod, by developing a significant power.

Dans la présente invention, l'énergie tirée du volant d'inertie sert à mettre en mouvement des roues, afin d'accélérer un système roulant. La de la planche unique est un schéma descriptif du système selon l'invention. En référence à cette , il est représenté en 1 la surface, appelée surface de référence, sur laquelle roulent une ou plusieurs roues 2 du système accélérateur selon l'invention, roues reliées, par l'intermédiaire d'un engrenage 3, à un premier planétaire 4 d'un mécanisme différentiel comprenant des pignons satellites 5, entraînés par un porte satellites 6, relié lui-même, par un engrenage 7, à un volant d'inertie 8. Un deuxième pignon planétaire 9 est relié, par l'intermédiaire d'un engrenage 10, à un disque de frein 11. Ce disque 11 coopère avec des mâchoires 12, susceptibles, en le serrant, de le faire ralentir. Lorsque le ralentissement du disque 11 et donc du planétaire 9 est obtenu, il s'en suit un ralentissement léger du volant d'inertie 8, mais surtout une accélération du premier planétaire 4 et donc des roues 2. Une part de l'énergie cinétique du volant d'inertie 8 est donc transmise aux roues 2, provoquant leur accélération. Quand il s'agit de véhicules terrestres, pour assurer la puissance nécessaire à la vitesse de croisière, un moteur 13, en général thermique ou électrique, est relié aux roues 2.In the present invention, the energy drawn from the flywheel is used to set the wheels in motion, in order to accelerate a rolling system. There of the single board is a descriptive diagram of the system according to the invention. With reference to this , there is shown at 1 the surface, called the reference surface, on which one or more wheels 2 of the accelerator system according to the invention roll, wheels connected, via a gear 3, to a first sun gear 4 of a differential mechanism comprising planet pinions 5, driven by a planet carrier 6, itself connected, by a gear 7, to an inertia flywheel 8. A second planetary pinion 9 is connected, via a gear 10, to a brake disc 11. This disc 11 cooperates with jaws 12, capable, by tightening it, of causing it to slow down. When the slowing down of the disc 11 and therefore of the sun gear 9 is obtained, there follows a slight slowing down of the flywheel 8, but above all an acceleration of the first sun gear 4 and therefore of the wheels 2. Part of the kinetic energy of the flywheel 8 is therefore transmitted to the wheels 2, causing their acceleration. When it comes to land vehicles, to provide the power necessary for cruising speed, a motor 13, generally thermal or electric, is connected to the wheels 2.

Ainsi qu'alors que, pour un véhicule de tourisme moyen, avec une vitesse de croisière de 130 km/h sur le plat et de 110 km/h dans une montée de 5 %, 60 kW suffisent, les constructeurs installent les moteurs d’environ 100 kW. Le système selon l'invention, en permettant l'installation de moteurs moins puissants, conduirait à des économies d'énergie et à la réduction des émissions de CO2. Le volant d’inertie 8 est mis en vitesse par un moteur 14 de préférence électrique. Pour les avions à propulsion partiellement ou totalement électrique, l'installation, en guise de train atterrissage, d'un système selon la présente invention, permettrait, au décollage, une accélération importante, raccourcissant ainsi considérablement la distance de décollage. Cette accélération dépend directement de la puissance de freinage de l’ensemble mâchoires 12, disque 11. De fait, c'est la tolérance des passagers à un certain degré d’accélération horizontale, qui limite cette accélération. Le système selon la présente invention, pouvant développer les énergies importantes, peut être utilisé comme catapulte pour un porte-avions.So whereas, for an average passenger vehicle, with a cruising speed of 130 km/h on the flat and 110 km/h uphill by 5%, 60 kW are sufficient, the manufacturers install the engines of about 100kW. The system according to the invention, by allowing the installation of less powerful motors, would lead to energy savings and the reduction of CO2 emissions. The flywheel 8 is set in motion by a motor 14, preferably electric. For aircraft with partially or totally electric propulsion, the installation, by way of landing gear, of a system according to the present invention, would allow, on takeoff, a significant acceleration, thus considerably shortening the takeoff distance. This acceleration depends directly on the braking power of the jaw assembly 12, disk 11. In fact, it is the tolerance of the passengers to a certain degree of horizontal acceleration, which limits this acceleration. The system according to the present invention, which can develop high energies, can be used as a catapult for an aircraft carrier.
