Abstract
Description
La présente invention concerne un dispositif de transmission hydrauliqueThe present invention relates to a hydraulic transmission device
temporaire supplémentaire pour rendre motrices des roues qui ne le sont pas originellement afin de gagner en performance sur terrains et routes difficiles. additional temporary to drive wheels that are not originally designed to gain performance on difficult terrain and roads.
Cette aide ponctuelle à la motricité n'est utilisable qu'à très basse vitesse (bridé par 05 un limiteur), avec une poussée constante en synchronisation ou non avec l'essieu moteur d'origine. This punctual help to the motricity is usable only at very low speed (clamped by a limiter), with a constant thrust in synchronization or not with the original drive axle.
Le dispositif est destiné aux véhicules routiers légers (VL) et véhicules utilitaires légers (VUL) Habituellement, une adaptation d'un système à 4 roues motrice sur une base automobile à 2 roues motrices est réalisée entre l'essieu moteur (boite/pont) et le nouvel essieu moteur avec un renvoi de couple par un arbre tournant traversant sous la caisse. The device is intended for light road vehicles (VL) and light commercial vehicles (VUL) Usually, an adaptation of a 4 wheel drive system on a 2 wheel drive car base is made between the drive axle (box / bridge) and the new drive axle with a torque return through a rotating shaft passing under the body.
Celui-ci alimente le nouveau pont qui redistribue le mouvement. This feeds the new bridge that redistributes the movement.
Si la voiture est une traction, on ajoute le système aux roues arrières. If the car is traction, we add the system to the rear wheels.
Si la voiture est une propulsion, on ajoute le système aux roues avants. If the car is a propulsion, the system is added to the front wheels.
Si la voiture d'origine n'a pas été prévue par construction pour recevoir un tel système, les modifications nécessaires imposent des transformations majeures comportant généralement une rehausse de la caisse pour passer l'arbre de transmission. If the original car was not planned by construction to receive such a system, the necessary modifications require major transformations generally comprising raising the body to pass the drive shaft.
La boite de vitesse et ses périphériques subissent également des changements importants afin de pouvoir prélever le mouvement. The gearbox and its peripherals also undergo significant changes in order to take the movement.
De plus, ces transformations alourdissent l'automobile de manière conséquente. Le dispositif concerné donne le bénéfice d'une transmission 4x4,sans les inconvénients de la transformation (comme décris ci-dessus) Le croquis annexé (FIG.1) illustre l'invention: La voiture de base a seulement 2 roues motrices que se soit à l'avant ou à l'arrière (rép.1 et 2), les roues non-motrices (rép.3 et 4) du véhicule sont équipées chacune d'un moteur hydraulique (rép.5 et 6) intégré dans leurs moyeux. Moreover, these transformations weigh heavily on the automobile. The device concerned gives the benefit of a 4x4 transmission, without the disadvantages of the transformation (as described above) The attached sketch (FIG. 1) illustrates the invention: The basic car has only 2 driving wheels that have been at the front or at the rear (resp. 1 and 2), the non-driving wheels (resp. 3 and 4) of the vehicle are each equipped with a hydraulic motor (resp. 5 and 6) integrated into their hubs .
Ces moteurs peuvent agir en prise directe ou par le biais d'un renvoi mécanique 30 (réducteur) Le fluide hydraulique (sous pression) nécessaire aux moteurs peut provenir: - Rép.7: d'une pompe entraînée par le moteur (rép.8) de la voiture; - Rép.9: d'une dérivation de la pompe de direction assistée d'origine de la voiture; - Rép.10: d'une centrale electrohydraulique à installer quelque part dans la voiture. These motors can act directly or by means of a mechanical gearbox (reducer). The hydraulic fluid (under pressure) necessary for the motors can come from: - Rep.7: from a pump driven by the motor (rep. ) of the car; - Rep.9: a derivation of the original power steering pump of the car; - Rep.10: an electrohydraulic power plant to install somewhere in the car.
Des tuyaux flexibles (rép.21) relient les moteurs à un bloc de distribution hydraulique (rép.16) et à la pompe (rép.7, 9 ou10) La mise en route du dispositif peut s'effectuer de 2 manières complémentaires par une commande au tableau de bord (rép.11) : - Mode manuel: le bouton active ou désactive le dispositif, il y a donc une poussée constante pour une durée décidée par l'utilisateur; - Mode automatique: il est géré par le calculateur du boîtier électronique additionnel (rép.12) qui prend en compte des paramètres (vitesse de rotation, patinage, différence de vitesse entre les roues, ... ) donné par des capteurs (ABS par exemple) des roues motrices d'origine (rép.13 et 14) branchés au calculateur d'origine (rép.15), et gère le bloc de distribution hydraulique (rép.16) qui active ou désactive le système en fonction des informations reçues. Flexible hoses (ref.21) connect the motors to a hydraulic distribution block (rep.16) and to the pump (resp. 7, 9 or 10) The device can be started up in 2 complementary ways by a command on the instrument panel (rep.11): - Manual mode: the button activates or deactivates the device, so there is a constant thrust for a duration decided by the user; - Automatic mode: it is managed by the computer of the additional electronic unit (rep.12) which takes into account parameters (speed of rotation, slip, speed difference between the wheels, ...) given by sensors (ABS by example) the original driving wheels (rep.13 and 14) connected to the original computer (resp.15), and manages the hydraulic distribution block (rep.16) which activates or deactivates the system according to the information received .
L'utilisateur, sans action de sa part, à ainsi la garantie d'avoir l'aide à la motricité automatiquement en cas de terrain accidenté, quel que soit le type et le niveau de 10 difficultés rencontré. The user, without any action on his part, thus has the guarantee of having traction assistance automatically in case of rough terrain, whatever the type and level of difficulties encountered.
Le boîtier électronique (rép.12) permet une répartition intelligente du fluide hydraulique par le bloc de distribution (rép.16) de manière optimale sur chacune des roues (indépendamment à droite et/ou à gauche) en terme débit et de durée, suivant une stratégie de gestion programmée au calculateur (plusieurs lois de fonctionnements possibles) grâce aux renseignements provenant des capteurs (ABS par exemple) des roues motrices temporaires (rép.17 et 18) Ceci a pour résultat de garantir la motricité du nouvel essieu moteur en cas de perte d'adhérence d'une roue (effet similaire à un différentiel autobloquant) Les éléments électroniques additionnels sont reliés entre eux et au calculateur d'origine par un faisceau électrique supplémentaire (rép.22) Le système de part sa conception et son utilisation ne peut fonctionner qu'à faible allure, une sécurité agit en liaison avec la vitesse du véhicule (mesure tachymètrique donnée par les capteurs (ABS par exemple) des roues motrices temporaires (rép.17 et rép.18), retransmise au boîtier électronique (rép.12) Si le seuil maximum programmé (limiteur de vitesse) au calculateur du boîtier électronique (rép.12) est dépassé, le dispositif se désactive automatiquement et reste 30 inactivable jusqu'a ce que la vitesse revienne en dessous de ce seuil. The electronic box (12) allows an intelligent distribution of the hydraulic fluid by the distribution block (16) in an optimal way on each of the wheels (independently on the right and / or on the left) in terms of flow and duration, according to a programmed management strategy to the computer (several operating laws possible) thanks to information from the sensors (ABS for example) temporary drive wheels (rep.17 and 18) This has the result of ensuring the motricity of the new driving axle in case loss of adhesion of a wheel (effect similar to a self-locking differential) The additional electronic elements are connected to each other and to the original computer by an additional electrical harness (ref.22) The system by its design and use can only operate at a low speed, safety acts in conjunction with the speed of the vehicle (tachometric measurement given by the sensors (ABS for example ) temporary drive wheels (17 and 18), retransmitted to the control unit (12) If the maximum programmed threshold (speed limiter) at the control unit of the control unit (12) is exceeded, the device automatically deactivates and remains inactivable until the speed returns below this threshold.
Egalement, dés que la pédale de frein (rép.19) ou que le frein à main (rép.20) sont actionnés, le système se désactive et reste inactivable tant que les dispositifs de freinage sont sollicités. Also, as soon as the brake pedal (resp.19) or the parking brake (rep.20) are actuated, the system switches off and remains inactive as long as the braking devices are stressed.
En mode manuel, si besoin, il faut réactiver le système par la commande au tableau de 35 bord (rép.11) En mode automatique, il y a une réactivation spontanée du système si les conditions d'évolution du véhicule le demandent. In manual mode, if necessary, it is necessary to reactivate the system by the control board (rep.11) In automatic mode, there is spontaneous reactivation of the system if the conditions of evolution of the vehicle require it.
Le montage de ce dispositif ne présente aucune réelle difficulté, cela par le caractère 40 léger et simple de l'installation, et notamment, grâce à l'emploi de tuyaux hydrauliques. The mounting of this device presents no real difficulty, that the character 40 light and simple installation, and in particular, thanks to the use of hydraulic hoses.
Le véhicule ne subit donc aucune modification de structure ou plate-forme, ce qui est garant d'un poids maîtrisé, d'économie (financière et en temps de conception/réalisation) et simplifie grandement les démarches administratives légales (homologation) Le dispositif transforme une classique automobile à 2 roues motrices en véhicule à capacités touschemins de premier ordre. The vehicle thus undergoes no modification of structure or platform, which guarantees a controlled weight, economy (financial and time of conception / realization) and greatly simplifies the legal administrative steps (homologation) The device transforms a classic 2-wheel drive automobile in first-class all-wheel-drive vehicles.
Par la nature même du dispositif, on ne peut pas réellement parler de transmission 4x4, mais plutôt de multiroues-motrices puisque l'entraînement des roues supplémentaires n'intervient qu'à basse vitesse, avec une poussée constante, indépendante de la transmission d'origine, et que dans certains cas de figures, l'électronique enverra le fluide sur une seule roue. By the very nature of the device, it is not really possible to speak of 4x4 transmission, but rather of multiroues-motrices since the drive of the additional wheels intervenes only at low speed, with a constant thrust, independent of the transmission of origin, and that in some cases, the electronics will send the fluid on a single wheel.
Il est à noter que: Par extrapolation, on peut imaginer monter le dispositif sur des voitures à plus de 4 15 roues. It should be noted that: By extrapolation, it is conceivable to mount the device on cars with more than 4 wheels.
Aux vues des caractéristiques sus-mentionnées, le système peut être proposé en 6 variantes: - Système 1: commande manuel seul (boîtier électronique en programmation de base pour la stratégie de sécurité) ; Système 2: système 1 avec en plus le boîtier électronique programmé pour répartition intelligente du fluide entre les roues motrices temporaires; Système 3: commande automatique, avec boîtier électronique programmé pour la détection de mise en route des roues motrices supplémentaires; Système 4: système 3 avec en plus le boîtier électronique programmé pour répartition 25 intelligente du fluide entre les roues motrices temporaires; - Système 5: système 3 plus système 1; - Système 6: système 4 plus système 1. In view of the above-mentioned features, the system can be offered in 6 variants: - System 1: manual control only (electronic control unit in basic programming for the security strategy); System 2: System 1 with the addition of the electronic control unit programmed for intelligent distribution of the fluid between the temporary drive wheels; System 3: automatic control, with electronic box programmed for detection of start-up of additional drive wheels; System 4: System 3 with in addition the programmed electronic box for intelligent distribution of the fluid between the temporary driving wheels; - System 5: system 3 plus system 1; - System 6: system 4 plus system 1.
La simplicité des composants et le fait qu'ils nécessitent que de légères adaptations pour le montage permet d'installer ce système dans n'importe qu'elle automobile. 30 The simplicity of the components and the fact that they require only slight adaptations for the assembly makes it possible to install this system in any automobile. 30
