Description

La présente invention concerne un dispositif de moto ricat ion de la roue avant d'une motocyclette et autres véhicules à deux roues. The present invention relates to a motorcycle ricat ion device of the front wheel of a motorcycle and other two-wheeled vehicles.

I1 est bien connu que l'absence de motorisation de la roue avant d'une motocyclette pénalise lourdement celle-ci lors des parcours en terrain boueux, sableux ou enneigé, par rapport aux automobiles et notamment celles équipées de quatre roues motrices et d'un dispositif de blocage du différentiel. I1 is well known that the lack of motorization of the front wheel of a motorcycle severely penalizes it during journeys in muddy, sandy or snowy terrain, compared to cars and in particular those equipped with four-wheel drive and a differential lock.

Des exemples récents, tels que le rallye PARIS-DAKAR, ont mon tr8 que les concurrents qui participaient à la compétition en moto- cyclette avaient à surmonter de grendes diffioultés pour maintenir leur engin en ligne, en terrain glissant,et sortir des ornières, du fait de l'absence de motorisation de la roue avant. Recent examples, such as the PARIS-DAKAR rally, have told me that the competitors who participated in the motorcycle competition had to overcome diffioult grends to keep their gear in line, in slippery terrain, and get out of ruts, due to the lack of motorization of the front wheel.

Le dispositif selon l'invention vise à remédier à cet incon vénient, car avec celui-ci, en effet, les motocyclettes peuvent être équipées de deux roues motrices, ce qui augmente considérablement leur adhérence et leur tenue de route. The device according to the invention aims to remedy this inconvenience, because with it, in fact, motorcycles can be equipped with two driving wheels, which considerably increases their grip and handling.

Ce dispositif se caractérise principalement en oe que la motorisation de la roue avant s'effectue par l'intermédiaire d'une transmission mécanique hydraulique ou éleotrique.  This device is mainly characterized in that the motorization of the front wheel is effected by means of a mechanical hydraulic or eléctric transmission.

La transmission mécanique est constituée d'un différentiel, d'un embrayage, d'un arbre de transmission à joints de cardans et fourreau coulissant relié par l'intermédiaire d'engrenages à axes courants, à un arbre de transmission à fourreau coulissant qui trans- met le mouvement à la roue par l'intermédiaire de deux engrenages à axes concourants ou d'une roue et d'une vis sans fin. The mechanical transmission consists of a differential, a clutch, a transmission shaft with cardan joints and a sliding sleeve connected by means of common axis gears, to a sliding sleeve transmission shaft which transmits - sets the movement to the wheel by means of two gears with concurrent axes or a wheel and a worm.

Selon un second mode de réalisatibn de l'invention, le dispositif est constitué d'un différentiel, d'un embrayage, d'un arbre flexible et de deux engrenages à axes concourants ou d d'une roue et d'une vis sans fin. According to a second embodiment of the invention, the device consists of a differential, a clutch, a flexible shaft and two gears with concurrent axes or d a wheel and a worm .

Selon un troisième mode de réalisation de l'invention, le dispositif est constitué d'un différentiel, d'une pompe, d'un distributeur, d'une tuyauterie d'alimentation, d'un moteur d'entranement de la roue avant et d'une tuyauterie de retour. According to a third embodiment of the invention, the device consists of a differential, a pump, a distributor, a supply pipe, a drive motor for the front wheel and return piping.

Selon un quatrième mode de réalisation de l'invention, le dispositif est constitué d'un différentiel, d'une génératrice, d'un contacteur-disjoncteur, d'un câble d'alimentation et d'un-moteur électrique. According to a fourth embodiment of the invention, the device consists of a differential, a generator, a contactor-circuit breaker, a power cable and an electric motor.

Tous les différentiels sont munis d'un moyen de blocage,et les embrayages des dispositifs de transmission mécanique sont constitués de crabots, et ceux des dispositifs de transmission hydrsulique et électrique sont constitués respectivement d'un distribnteur et d'un contact eur-dis jonot eur0

En se reportant successivement aux figures I à 4, on remarque que s
- Selon la première version, le dispositif mécanique de motori- sation de la roue avant est conetitué d'un différenilel I, relié à l'arbre de sortie de la boîtr de vitesses, d'un embrayage à orabots ou hydraulique 2, d'un arbre primaire 3, à joints de cardans et fourreau coulissant, entraînant, par l'intermédiaire d'engrenages à axes concourants 4 et 5, un arbre secondaire 6, à fourreau coulissant, transmettant le mouvement à la roue avant par l'intermédiaire d'engrenages à axes concourants 7 et 8.Referring successively to Figures I to 4, we note that s
- According to the first version, the mechanical motorization device of the front wheel is made up of a differential I, connected to the output shaft of the gearbox, of a orabot or hydraulic clutch 2, of a primary shaft 3, with cardan joints and sliding sleeve, driving, by means of gears with concurrent axes 4 and 5, a secondary shaft 6, with sliding sleeve, transmitting the movement to the front wheel by means of '' gears with concurrent axes 7 and 8.

- Selon la seconde version, le dispositif mécanique de motorisation de la roue avant est constitué d'un différentiel I reUé à l' arbre de sortie de la boite de vitesses, d'un embrayage à crabots ou hydraulique 2, d'un arbre flexible 9 et d'engrenages a axes concou- rants 10 et II.  - According to the second version, the mechanical device for motorizing the front wheel consists of a differential I reUé to the output shaft of the gearbox, of a dog clutch or hydraulic 2, of a flexible shaft 9 and gears with concurrent axes 10 and II.

- Selon la troisième version, le dispositif hydraulique de motorisation de la roue avant est constitué d'un différentiel I relié à l'arbre de sortie de la boîte de vitesses, d'une pompe 12, d'un distributeur I3, d'une tuyauterie d'alimentation 14, d'un moteurhy- draulique 15 et d'une tuyauterie de retour 16. - According to the third version, the hydraulic device for motorizing the front wheel consists of a differential I connected to the output shaft of the gearbox, a pump 12, a distributor I3, a supply piping 14, a hydraulic motor 15 and a return piping 16.

- Selon la quatrième version, le dispositif 6lectrique de moto- risation de la roue avant est constitué d'un différentiel I, relié à -l'arbre de sortie de la botte de vitesses, d'une génératrice ou alternateur I7, d'un contacteur-disjoncteur I8, d'un cable d'alimentation 19 et d'un moteur électrique d'entratnement 20. - According to the fourth version, the electric motorization device of the front wheel consists of a differential I, connected to the output shaft of the gear boot, of a generator or alternator I7, of a contactor-circuit breaker I8, a power cable 19 and an electric drive motor 20.

Ainsi, quelle que soit la version, la roue motrice pourra être motorisée ou libérée à volonté par l'intermédiaire de l'embrayage constitué, selon la version, d'un embrayage à crabots 2, d'un embrayage hydraulique, d'un distributeur 13 ou d'un contacteur-disjoncteur I8.  Thus, whatever the version, the drive wheel can be motorized or released at will via the clutch consisting, depending on the version, of a dog clutch 2, a hydraulic clutch, a distributor 13 or of a contactor-circuit breaker I8.

Par ailleurs, la présence d'un différentiel, avec possibilité de blocage de celui-ci, facilitera, lorsque la motorisation de la roue avant sera enclenchée les prises de virages courts sans dérapage de la roue arrière. In addition, the presence of a differential, with the possibility of locking it, will facilitate, when the motorization of the front wheel is engaged short cornering without skidding the rear wheel.

L'action de ce différentiel pourra être annulée par blocage pour faciliter la sortie des ornières et des passages boueux ou en neigés. The action of this differential can be canceled by blocking to facilitate the exit of ruts and muddy or snowy passages.

La présence de joints de cardans et d'un fourreau coulissant sur l'arbre primaire, ainsi que d'un fourreau coulissant sur l'arbre secondaire, garantit une totale liberté de débattement de la fourche et des amortisseurs dont celle-ci est généralement équipée. The presence of universal joints and a sliding sleeve on the primary shaft, as well as a sliding sleeve on the secondary shaft, guarantees total freedom of movement of the fork and the shock absorbers with which it is generally equipped. .

Ce dispositif est destiné principalement à transformer les motocyclettes routières en motocyclettes tous terrains. This device is mainly intended to transform road motorcycles into all-terrain motorcycles.

L'invention revêt un intérêt particulier pour les motocyclettes tous terrains ou de compétition mais aussi pour les autres véhicules à deux roues.  The invention is of particular interest for all-terrain or competition motorcycles but also for other two-wheeled vehicles.
