Abstract
Description
Système ensemble moto-directeur Motorcycle steering system
La présente invention concerne un ensemble moto-directeur destiné essentiellement à être adapté à un véhicule routier. The present invention relates to a motor-steering assembly intended essentially to be adapted to a road vehicle.
La fonction motrice étant assurée par un moteur électrique dont la vitesse est contrôlée électroniquement. Dans les véhicules classiques la fonction moteur est généralement assurée par un bloc moteur thermique suivi d'une chaîne d'organes complexes (embrayage, boîte de vitesse, cardans...) avant d'aboutir aux roues. The motor function is provided by an electric motor whose speed is controlled electronically. In conventional vehicles the engine function is usually provided by a thermal engine block followed by a complex chain of organs (clutch, gearbox, gimbals ...) before reaching the wheels.
Quant à la fonction de direction elle est assurée indépendamment, de façon mécanique ou électrique. Les deux fonctions se rejoignent au niveau des roues. La particularité du système classique décrit est que le système directionnel s'opère par rotation de chaque roue directrice autour d'un axe vertical, ce qui engendre de grands frottements sollpneu (d'où le besoin de direction assistée). Quant aux moteurs thermiques, ils émettent, même au ralenti, de grandes quantités de polluants chimiques (C, Co, Co2, Nox...) et sonores. L'invention concerne un ensemble moto-directeur dont la caractéristique principale est de regrouper ou supprimer les organes classiques liés au couple moteur/direction, afin de former un ensemble monolithique solidarisé au véhicule par un système d'amortisseurs. Il est conçu pour limiter les consommations d'énergie tant dans sa fabrication que dans son utilisation. Cet ensemble assure simultanément les fonctions de direction d'entraînement marche avant / marche arrière et de freinage. As for the steering function it is provided independently, mechanically or electrically. Both functions meet at the wheels. The peculiarity of the conventional system described is that the directional system operates by rotation of each steering wheel about a vertical axis, which generates great friction sollpneu (hence the need for power steering). As for thermal engines, they emit, even at idle, large amounts of chemical pollutants (C, Co, Co2, Nox ...) and sound. The invention relates to a motor-steering unit whose main feature is to group or remove conventional members related to the engine / steering torque, to form a monolithic assembly secured to the vehicle by a damping system. It is designed to limit energy consumption both in its manufacture and its use. This assembly simultaneously provides forward / reverse drive direction and braking functions.
L'assemblage (figure 1) et la chaîne cinématique qui en découle permettent une rotation de +1- 30° par rapport à l'axe vertical. La disposition des suspensions permet d'absorber des dénivellations d'un rapport de 1 sur 2. L'ensemble moto-directeur se présente sous la forme d'un cylindre contenant la partie motrice à deux axes de sortie sur lesquels sont fixées des platines supportant directement les freins à disques et les jantes (figure 1). Dans le cas de deux moteurs identiques montés dos à dos l'effet directionnel peut être obtenu par un déphasage temporaire de l'excitation du stator, cette solution élimine tout système directionnel à commande mécanique. The assembly (Figure 1) and the kinematic chain that results allow a rotation of + 1- 30 ° with respect to the vertical axis. The arrangement of the suspensions makes it possible to absorb unevenness of a ratio of 1 in 2. The motor-steering unit is in the form of a cylinder containing the driving part with two output shafts on which are fixed plates supporting directly the disc brakes and rims (Figure 1). In the case of two identical motors mounted back to back the directional effect can be obtained by a temporary phase shift of the excitation of the stator, this solution eliminates any directional system with mechanical control.
Le moteur électrique peut être de tous types connus à ce jour ou de future conception et son électronique de commande adaptée à celui-ci. Il doit néanmoins posséder un couple suffisant pour entraîner directement les roues. The electric motor can be of any type known to date or future design and its control electronics adapted to it. It must nevertheless have enough torque to drive the wheels directly.
Par exemple un moteur alternatif multipôle 600t/mm permet d'obtenir une vitesse de 45Km/h. L'accélération et le freinage du moteur sont assurés par une électronique qui gère aussi la récupération d'énergie lors des freinages et des descentes. Le mode de commande peut être 5 au niveau des mains ou des pieds du conducteur. Pour palier le différentiel de vitesse des roues lors des changements de direction, le système moto-directeur intègre l'un des composants suivants : différentiel à engrenage entre le moteur et les roues. moteur à stator unique et deux rotors indépendants 10 La particularité de ce système libère les roues à l'arrêt et permet une rotation sans contrainte mécanique donc sans direction assistée ni usure des pneumatiques. La fonction direction de ce système est commandée par un ensemble roue et vis tangente afin de prévenir toute déviation de l'ensemble moto directeur par un obstacle ou un trou rencontré par l'une ou les deux roues. La position des amortisseurs accompagne ce 15 dispositif de sûreté. La partie moteur peut être aussi utilisée seule dans le cas de véhicule à 3 ou 4 roues, la direction étant assurée alors par un système classique. La figure 1 représente l'ensemble moto-directeur associé au véhicule, l'ensemble des pièces mécaniques représentées, en dehors des roues (14) et des jantes (15), fait partie 20 intégrante et est lié au brevet. Les figures 2 et 3 représentent les deux dispositifs différentiels. Le montage de deux moteurs dos à dos ne nécessite pas de représentation. La chaîne cinématique, ensemble moto-directeur/ véhicule, est assurée par le bloc moteur (8), la pllatine (9), le tube coulissant (5), la tige (3), commander par la roue et vis 25 tangente (1). Les éléments de suspension sont assurés par les amortisseurs (6), le ressort (2), les butées progressives (10). Ces dernières limitent l'amplitude du mouvement par rapport à l'axe D. Les liaisons électriques ne sont pas représentées afin de faciliter la lecture des plans, 30 elles se font au niveau de l'axe A. Les marches avant et arrière se font par inversion de sens de rotation du moteur et défini par la chaîne cinématique suivante: axes B et C schémas (10)-(11)-(12)-(13)-(16)-(15)-(14). La figure 2 représente la particularité du rotor (21) serti dans le tube (24) lié par des 35 pignons de différentiels (23) solidarisés par l'axe (22) aux arbres des sorties (28). La figure 3 représente deux rotors (33 et 35) indépendants l'un de l'autre et solidaires de leurs axes de transmission respectivement (36 et 40). L'axe (38) se trouve libre de rotation via un palier (34) de type rondelle ou roulement à billes. For example, a 600t / mm multi-pole reciprocating motor makes it possible to obtain a speed of 45Km / h. Acceleration and braking of the engine are provided by electronics that also manages energy recovery during braking and descents. The control mode may be at the driver's hands or feet. To compensate for the differential speed of the wheels when changing direction, the motor-steering system incorporates one of the following components: gear differential between the engine and the wheels. single stator motor and two independent rotors 10 The particularity of this system frees the wheels at a standstill and allows a rotation without mechanical stress, thus without power steering or tire wear. The steering function of this system is controlled by a wheel and tangent screw assembly to prevent any deviation of the steering motor assembly by an obstacle or a hole encountered by one or both wheels. The position of the dampers accompanies this safety device. The motor part can also be used alone in the case of vehicle with 3 or 4 wheels, the direction being ensured then by a conventional system. Figure 1 shows the motorcycle-associated assembly associated with the vehicle, all the mechanical parts shown, apart from the wheels (14) and rims (15), is an integral part and is related to the patent. Figures 2 and 3 show the two differential devices. Mounting two motors back to back does not require representation. The drivetrain, together motor-steering / vehicle, is provided by the engine block (8), the pllatin (9), the sliding tube (5), the rod (3), control by the wheel and screw tangent (1). ). The suspension elements are provided by the dampers (6), the spring (2), the progressive stops (10). These limit the amplitude of the movement relative to the axis D. The electrical connections are not shown to facilitate the reading of the plans, 30 they are at the axis A. The front and back steps are done by reversing the direction of rotation of the motor and defined by the following kinematic chain: axes B and C diagrams (10) - (11) - (12) - (13) - (16) - (15) - (14). FIG. 2 shows the particularity of the rotor (21) crimped into the tube (24) linked by differential gears (23) secured by the axis (22) to the output shafts (28). Figure 3 shows two rotors (33 and 35) independent of each other and integral with their transmission axes respectively (36 and 40). The shaft (38) is free to rotate via a bearing (34) of the washer or ball bearing type.
