L'objet de l'invention, c'est l'engin capable d'assurer l'u tilisation d'un grand nombre d'outils utilisant I'hydraulique, 1' engin étant en outre automoteur et disposant en alternance ou simultanément de l'hydraulique pour la translation, la direction et la suspension. The object of the invention is the machine capable of ensuring the use of a large number of tools using hydraulics, the machine being furthermore self-propelled and alternately or simultaneously having the for travel, steering and suspension.

Toutes les application énumérées ci-dessus existent mais font appel à des engin différents les uns des autres, alors que l'engin décrit ci-apres satisfait aux conditions d'utilisation de tous. All the applications listed above exist but use different devices from each other, while the device described below meets the conditions of use of all.

A titre d'exemple il est connu qu'une municipalité ou un service équipement dispose de pelle rétro et de débroussailleuse ou de fraise à neige mais actuellement ces services disposent de trois unités bien distinctes, de trois porteurs différents qui sont utisés de façon saisonnière et sur stock le reste du temps. L'engin qui est présenté est utilise en permanence au fur et à mesure des besoins en adaptant l'outil nécessaire au travail demandé. De plus cet engin est utilisable sur chantier mobile comme source d'énergie pour plusieurs machines, ou comme à l'atelier. For example, it is known that a municipality or an equipment service has a backhoe and a brush cutter or a snow blower, but currently these services have three very distinct units, three different carriers which are used seasonally and on stock the rest of the time. The machine that is presented is used continuously as and when required by adapting the tool necessary for the work requested. In addition, this machine can be used on mobile sites as an energy source for several machines, or as in the workshop.

De plus la diversité des outils que l'on désire monter sur cet engin a conduit à une recherche en hydraulique qui confère à la centrale des caractéristiques très variées. Ce fait permet de disposer sur l'engin d'une motricité à très fort couple à basse vitesse et à assurer également une grande vitesse de translation ce qui rend ce 4 x 4 très performant sur les terrains accidentés. In addition, the diversity of tools that we want to mount on this machine has led to research in hydraulics which gives the plant very varied characteristics. This fact makes it possible to have very high torque on the machine at low speed and also to ensure a high speed of translation which makes this 4 x 4 very efficient on uneven terrain.

L'objet de la présente invention est bien l'engin mais il est évident que les outils adaptables sont associés à sa conception, et pour la simplification de la description nous suppose-ç) rons que les outils existent et nous ne nous étendrons pas sur leur description. The object of the present invention is the machine, but it is obvious that the adaptable tools are associated with its design, and for the simplification of the description we assume that the tools exist and we will not expand on their description.

En se référant à la planche 1, nous voyons que l'engin repose sur 4 roues A et en les roues A sont directrices et motrices elles sont aussin débrayables et peuvent fonctionner en roue libre, on peut considerer que chacune des roues est un outil entrainé en rotation avant ou arrière par moteur hydraulique. Les quatre roues étant interchangeables et on pourrait mme imaginer que la roue de secours de l'engin comporte également lgentrainement hy draulique, ce qui revient à dire que si l'engin était amené en usine il pourrait être procédé comme suit
- pour déplacer une lourde. machine, on démonterait les roues telles que représentées sur la planche 2 On fixerait à la machine le support de roue F et grâce à la liaison par flexible G on motoriserait la machine pour la déplacer.Referring to plate 1, we see that the machine rests on 4 wheels A and in the wheels A are steered and driving they are also disengageable and can operate in free wheel, we can consider that each of the wheels is a driven tool in front or rear rotation by hydraulic motor. The four wheels being interchangeable and one could even imagine that the spare wheel of the machine also includes hydraulic hydraulics, which amounts to saying that if the machine was brought to the factory it could be proceeded as follows
- to move a heavy. machine, the wheels as shown on plate 2 would be dismantled. The wheel support F would be fixed to the machine and, thanks to the hose connection G, the machine would be motorized to move it.

Ceci n'étant qu'un exemple d'utilisation montrant que la liaison roue-engin sera très simple et montrant également que 1' engin que nous décrivons n'est en rien comparable avec les tracteurs existants. This is only an example of use showing that the wheel-machine link will be very simple and also showing that the machine we are describing is in no way comparable with existing tractors.

Revenons à la planche 1 pour voir que l'engin a évidemment un chassis sur lequel repose l'unité de puissance I et le dispositif de commande J. Let's go back to Plate 1 to see that the machine obviously has a chassis on which the power unit I and the control device J. rest.

Etendons nous d'abord sur le chassis représenté sur la planche 2. Let’s first expand on the chassis shown on Plate 2.

Le chassis est constitué principalement de deux largeurs L creux, d'une embase percée N, de poutres M et M' et d'une cavité permettant l'installation du moteur thermique et des pompes. LA conception a ceci de particulier que le chassis à forte inertie mais faible épaisseur constitue le réservoir d'huile, cela a pour intérêt d'avoir un centre de gravité lé plus bas possible et permet également un excellent échange thermique grâce aux surfaces beaucoup plus importantes que sur une bache classique. The chassis mainly consists of two hollow widths L, a pierced base N, beams M and M 'and a cavity allowing the installation of the heat engine and pumps. THE design has the particularity that the chassis with high inertia but small thickness constitutes the oil tank, this has the advantage of having a center of gravity as low as possible and also allows an excellent heat exchange thanks to the much larger surfaces than on a classic tarpaulin.

Les embases N percées permettent de disposer les roues suivant l'empattement et la voie désirée. En effet il est important d'avoir un faible empattement à basse vitesse sur des terrains très difficiles par contre il est souhaitable de l'augmenter pour la translation à vitesse élevée sur la route. Même remarque pour la voie. The drilled N bases allow the wheels to be arranged according to the wheelbase and the desired track. In fact, it is important to have a small wheelbase at low speed on very difficult terrain, however it is desirable to increase it for driving at high speed on the road. Same remark for the track.

Quant aux poutres M et M', elles sont démontables et constituent les embases de fixation des outils, tels que : pelle rétro, charcheuse, tarière et lame de bull. As for the beams M and M ', they are removable and constitute the mounting bases for tools, such as: backhoe, loader, auger and bull blade.

Le logement K permet le montage de moteurs et pompes flaquées de différents modèles. Housing K allows the mounting of motors and puddled pumps of different models.

La cabine 0 constitue l'élément de protection des occupants du véhicule, cette cabine est aisément démontable; elle ne présente pas de particularité si ce n'est le désign qui lui sera donné. Cabin 0 constitutes the element for protecting the occupants of the vehicle, this cabin is easily removable; it does not present any particularity except the designation which will be given to it.

Le groupe de puissance I a ceci de particulier qu'il constitue une ensemble complet moteur thermique et un ensemble de pompes le dispositif de commande J étant également fixé que le dit ensemble. Ceci signifie que l'ont peut imaginer que pour des travaux fixes ne nécessitant pas de déplacement on peut se rendre acquereur uniquement du groupe avec'ou sans chassis selon qu'on désire-ou non conserver le même réservoir hydraulique. Cet ensemble étant comparable à un groupe électrogène. The power group I has the particularity that it constitutes a complete thermal engine assembly and a set of pumps, the control device J also being fixed as the said assembly. This means that we can imagine that for fixed works that do not require displacement, we can only acquire the group with or without chassis depending on whether or not we want to keep the same hydraulic tank. This set being comparable to a generator.

La commande J présente la particularité de constituer l'élément unique de conduite de l'engin en déplacement. Elle est constituée par une sorte de volant qui commande par rotation un distributeur agissant sur les roues directrices pour.les faire braquer dans un sens ou l'autre par un vérin hudraulique. Le volant est également articulé suivant un axe perpendiculaire au premier, cette articulation assurant marche avant et marche arrière suivant qu'on le déplace vers l'avant ou vers l'arrière. Et ce mouvement entraine une accélération lorsqu'on s'en rapproche. Cet engin se conduit d'une seule main. L'arret parking étant donné par un levier qui
agit sur un distributeur isolant les moteurs hydrauliques des
roues et des pompes.The command J has the particularity of constituting the single element for driving the moving vehicle. It is constituted by a kind of flywheel which controls by rotation a distributor acting on the steered wheels to make them turn in one direction or the other by a hydraulic jack. The steering wheel is also articulated along an axis perpendicular to the first, this articulation ensuring forward and reverse direction depending on whether it is moved forward or backward. And this movement leads to an acceleration when one approaches it. This machine is operated with one hand. The parking stop given by a lever which
acts on a distributor isolating the hydraulic motors of
impellers and pumps.

L'hydraulique installée sur cet appareil est représentée
schématiquement et à titre purement Indicatif sur la planche 4
On trouve le moteur thermique S qui actionne les pompes
- R : -débit variable ,c 20 cm3/tour,
- R' : débit variable : 20 cm3/tour,
- Q : débit constant : 20 cm3/tour,
- Ql : débit constant : 15 cm3/tour,
- Q" : débit constant : 10cm3/tour,
- V : débit constant : 5 cm3/tour.The hydraulics installed on this device is shown
schematically and purely for information on Plate 4
We find the heat engine S which drives the pumps
- R: -variable flow, c 20 cm3 / revolution,
- R ': variable flow: 20 cm3 / revolution,
- Q: constant flow: 20 cm3 / revolution,
- Ql: constant flow: 15 cm3 / revolution,
- Q ": constant flow: 10cm3 / revolution,
- V: constant flow: 5 cm3 / revolution.

Les pompes Q et Q' sont branchées sur un distributeur P qui permet d'envoyer la puissance soit aux outils soit à un ensemble de distributeurs T qui sélectionne les roues à motoriser. The pumps Q and Q 'are connected to a distributor P which allows power to be sent either to the tools or to a set of distributors T which selects the wheels to be motorized.

Cet ensemble de pompes comporte donc d'utilisation de deux débit variable quel que soit la rotation du moteur thermique et sans laminage, ainsi que quatre débit constant d'inégale valeur afin de satisfaire aux exigences de la variété d'outils utilisables. This set of pumps therefore comprises the use of two variable flow rates whatever the rotation of the heat engine and without rolling, as well as four constant flow rates of unequal value in order to meet the requirements of the variety of tools that can be used.

Il faut noter que la pompe V est aussi utilisée pour la direction. Note that pump V is also used for steering.

En ce qui concerne la translation hydrostatique, il faut rappeler que la variation de débit d'une pompe ne permet pas de fonctionner avec un couple satisfaisant au delà d'un rapport de variation de 1 à 25 ce qui impose d'ajouter à l'hydraulique un rapport mécanique aussi il a été conçu le dispositif suivant, dispositif donné à titre indicatif mais pour lequel nous avons chiffré les valeurs afin d'en faciliter la lecture. With regard to the hydrostatic translation, it should be remembered that the variation in flow rate of a pump does not allow it to operate with a satisfactory torque beyond a variation ratio of 1 to 25, which requires adding to the hydraulic a mechanical report also the following device was designed, device given as an indication but for which we have quantified the values in order to facilitate the reading.

Les roues U1 et U2 disposent de moteurs de 125 cm3. The U1 and U2 wheels have 125 cc engines.

Les roues U3 et U4 disposent de moteurs de 315 cm3. The U3 and U4 wheels have 315 cc engines.

Lorsque une seule pompe R est utilisée pour actionner les quatre roues motrices on obtient
pour une circonférence de roulement de 2,5m et un moteur thermique réglé à 3000 tours
- Débit de la pompe : 20 x 3000 = 60 000 cm3
- Capacité des quatre moteurs : (315x2) (125x2) = 880 cm3
- Vitesse de l'engin : 60 000 x 2,5 = 170m/mn soit 10 km/heure 880
avec couple de : 300 mkg par exemple. When only one R pump is used to operate the four-wheel drive we get
for a rolling circumference of 2.5m and a heat engine set to 3000 revolutions
- Pump flow: 20 x 3000 = 60,000 cm3
- Capacity of the four engines: (315x2) (125x2) = 880 cm3
- Machine speed: 60,000 x 2.5 = 170m / min or 10 km / hour 880
with torque of: 300 mkg for example.

Lorsque les pompes R, R' et Q débitent dans les moteurs Ul et
U2 uniquement des débit donnent : 180 000 cm3.When the pumps R, R 'and Q flow in the motors Ul and
U2 only flow rates give: 180,000 cm3.

- capacité des deux moteur : 250 cm3
- vitesse de l'engin 18 25 o x 2,5 = 1 800 M/MN = 108 km/h
avec couple de 25 mkg.- capacity of the two engines: 250 cc
- machine speed 18 25 ox 2,5 = 1,800 M / MN = 108 km / h
with 25 mkg torque.

Bien sûr, cet exemple n'est qu'une figuration des possibilités de ce type de transmission, il parait raisonnable de réaliser sur engin capable de disposer de O à 60 km/h. Of course, this example is only a representation of the possibilities of this type of transmission, it seems reasonable to achieve on a machine capable of having O at 60 km / h.

Il faut aussi ajouter que ce type de transmission permet l'utilisation de l'engin chenillard avec contrôle des vitesses des roues de droite ou de gauche. It should also be added that this type of transmission allows the use of the chasing machine with speed control of the right or left wheels.

L'ensemble hydraulique monté sur cet engin permet également de monter les roues planche 2 avec un dispositif d'élévation. The hydraulic assembly mounted on this machine also makes it possible to mount the board 2 wheels with a lifting device.

Le vérin X agissant sur le coulisseau W permet en effet d'assurer l'assiette de l'engin en terrain dénivelé par le travers.  The actuator X acting on the slide W in fact makes it possible to ensure the attitude of the machine in uneven terrain through the cross.
