Amphibienfahrzeug

[0001] From the conditions of the technology various amphibious vehicles are well-known in the different versions. Likewise there are while stationary the technology such amphibious vehicles in the most diverse sizes and for most diverse applications.

Fundamentally always one tries to correspond ashore in the best possible way to a land vehicle and the water in the best possible way a boat.

With the subject of the available invention at the basis lying development this was reached easily and way, whereby there are depending upon kind of the remarks hardly restrictions of the land fitness and in the water practically the advantages of a Katamaranbootes, which is not laterally tiltable, are reached.

The subject of the invention is in accordance with requirement 1 a new amphibious vehicle for progressive movement to water and to country with a waterproof, drip-tray type vehicle trunk with usual KFZ equipment with power supply unit, at least three wheels and a usual with the necessary controls equipped marine engine as well as with at least a flotation chamber, which are characterized by it, - that the vehicle trunk reciprocally toward downward open, essentially longitudinal recessing parallel to the vehicle longitudinal axis and/or - exhibits recesses, into which by means of at the vehicle trunk in particular outside arranged Einziehund driving out mechanisms two flowtechnically favorably formed, and prefer-proves with the lower surface of the trunk agreeing lower surface in the drawn in condition exhibiting, flotation chambers for land trips on the wheels upward retractably or swingable and - from which for water trips by means of the mechanics mentioned the two flotation chambers mentioned under rise of the vehicle trunk with the wheels essentially over the Wasserlinie on and/or into the water after downward lowerable or turnable are.

The special at this development is the way, how the transformation of the vehicle in the water and at the country is realized, whereby the drives themselves do not represent a new development.

For the water a usual ship's propeller screw and for the country the usual propelled and running along wheels are preferably used.

The transformation of the country into a vessel is made possible by the two lowerable flotation chambers. The new amphibious vehicle consists of a main trunk, which corresponds for instance to the body of a KFZ. This main trunk is only additionally tub-shaped implemented. In the main trunk are all components necessary for the drive ashore and water.

A usual outboard motor serves for the drive in the water. This has the advantage that are anyhow tiltable stored this kind of drives and can thus the respective depth of the vehicle adapt. However all well-known water drive systems can be used to adapt with the possibility indicated above, the different depth.

For the land drive wheels are installed at the main trunk of the new vehicle. These are installed as at a vehicle body. Accordingly the same are also equipped with usual Antriebsund control elements. Only the drive components must be technically so arranged to the wheels and the steering element that these lead in the best possible way waterproof from the tub-shaped main trunk. The kind of the drive and/or the number of driven wheels is free depending upon intended purpose to select. Crucially with the fact it is only that the wheels can be arranged in such a way that a sufficient Bodenfrei1/lO sterreichisches patent office is given to RK 12,761 U1 2012-11-15 heit to the floor space of the main trunk.

Thus a trip turned around even in the more difficult area, like for example with the transition of water to the country and/or, given. It can find the usual technology use in this way.

The control elements are as usual on a control stand. From this the individual drives can be regulated einund switched off as well as.

The steering of the front wheels during trips at the country and/or steering the Außenborders is realised with for example a plunger pump at the timing gear, whereby the two hydraulic circles with a single solenoid valve are changed over, with which it is possible to operate the tax cylinders of both systems separately.

With the main trunk are also both the flotation chamber tiltable into the lateral longitudinal recessing arranged.

Preferably these are attached in such a way that they integrate themselves as it were into the main trunk. By the fact one reaches that the new vehicle does not exhibit Uberbreite.

The flotation chambers prefer-proves lifted lowered by means of parallelogram impulse and.

Accordingly it is in accordance with requirement 2 planned that on each side of the vehicle trunk at the same at least in each case two, preferentially, to each other swivel arms tiltable from each other arranged in the distance operatable by means of the power supply unit in parallel position to the vehicle longitudinal axis are linked, - for drawing in and lowering the flotation chambers - under training of a parallelogram impulse, at their free ends over in the same distance linking at the flotation chambers, in particular there interiorlateral, from each other arranged, articulated connected are.

For the handling characteristics in the water those work themselves, prefer-prove to the rear swivelled, flotation chamber positively out. The hydraulic cylinder for example applicable for lowering by an electrohydraulical pump are propelled. The change-over takes place by means of single solenoid valves, whose controls are at the instrument panel and/or control stand of the new vehicle.

In the same way pneumatic, mechanical or electromechanical drives can be used for moving the flotation chambers.

In accordance with an execution variant, see requirement 3, can be intended that on each side of the vehicle trunk at the same at least in each case two are arranged in the distance from each other, preferentially by means of the power supply unit operatable, to each other parallel arranged, if necessary with appropriate linking at the vehicle trunk and at the flotation chambers equipped, if necessary tiltable, hydraulic arms, which - for drawing in and lowering the flotation chambers - are connected with the flotation chambers at their free ends.

In particular regarding the quality of the conditions and driving ashore it is favorably, if it, as in accordance with requirement 4 intended, exhibits altogether four wheels, by which two transverse to the vehicle longitudinal axis in the distance from each other independently rotatable or over a differential gear is propelable and the other two wheels at one, vertical, steering axle arranged, guidable pair of dual wheels prefers forms.

Further it is favourable in accordance with requirement 5, if the new vehicle - for the drive and the steering element during trip on the water with lowered and/or driven out flotation chambers - is equipped with a conventional, the ship's propeller screw or, tiltable outer Benbordantrieb lowering the water output under the Wasserlinie.

The wheels are favorable-prove so arranged that they do not collide when swivelling or driving the flotation chambers out with the same. In the prototype for this purpose a 3-Rad similar arrangement was selected, thus guidable front wheels in dual wheel execution.

sterreichisches patent office RK 12,761 U1 2012-11-15 in the brought in condition are the flotation chambers favourable-proves with the ground of the main trunk almost concisely. This ensures that the clearance is ashore without reservation given. The outboard motor inclusive marine propeller or such a thing tilted up here, so that also as a result of the marine propeller no reduction of the clearance arises. The amphibious vehicle can move thereby in a suitable place of the country in the water, since sufficiently clearance is present.

In the following the practical function of the new amphibious vehicle is more near described:

TRANSITION FROM THE COUNTRY TO THE WATER:

The vehicle drives with still brought in flotation chambers into the water. With the land drive over the wheels it is thus possible to drive far enough in the water around sufficient depth of water for the water drive to reach. On the one hand the wheels propelled still help, which in the water for a certain propulsion to provide.

If sufficient depth of water is given, the water drive is thus activated, Außenborder. The outboard motor is so far lowered that the ship's propeller screw is sufficiently in the water, in order to take over the propulsion.

In order to reduce the water resistance, further the two flotation chambers are driven out. The vehicle trunk begins itself to lift from the water, until only more are in the long run katamaranähnlichen flotation chambers in the water. Now the wheels are practically complete above the Wasserlinie.

The water resistance corresponds now to that of a Katamarans, likewise the good stable handling characteristics. The new amphibious vehicle can move itself now also with a small drive power economically with the help of the marine propeller.

TRANSITION OF THE WATER ON THE COUNTRY:

If one liked to move now the vehicle of the water on the country, one brings the flotation chambers in completely in the low bank water. The outboard motor so far upward swivelled that on the one hand the shank of the outer one has ßenborders a certain safety margin to the wheel lower edge, on the other hand however still the marine propeller in the water is, in order to still ensure the drive in the water straight, in addition, the drive wheels can be in addition-switched with small number of revolutions.

In this arrangement the wheels before the Unterschiff reach the reason, in addition, the ship's propeller screw is in a relatively protected position.

If the propelled wheels have again sufficiently ground contact, the outboard motor can be tilted up and switched off completely and it is again the whole clearance given.

In case of the prototype, which was laid out particularly as bath vehicle, a further advantage of the extendable flotation chambers results: The vehicle can lie in the shallow water calmly and surely, without having to anchor. But the vehicle can lie also on the wheels if it on firm reason stands.

The water may not become so deep however that the lift strength brings the new vehicle to drifts.

In summary it is to be noted that by aufund the abbeweglichen flotation chambers the vehicle can be converted from an almost full land vehicle to an full Katamaran. In the case of trips in the water still further advantages can arise as a result of purposeful lifting and lowering of the flotation chambers, since the handling characteristics of the amphibious vehicle of the speed, to which use and the respective wave course can be adapted.

sterreichisches patent office RK 12,761 U1 2012-11-15 the substantial advantages of the new amphibious vehicle are to be set up as follows:

It is water suited landund, it is for very comfortable space conditions, inclusive of large couch surfaces, anyhow in relation to the boat size, it is designed designed for a calm Dahingleiten on smaller distances, however with high comfort and it offers in particular bath fun at the sea for cosy exits.

The new vehicle is suited also at the country, which is reached by the two hebund lowerable swimming skids or - bodies.

In the water these are lowered, so that arrives, to passenger compartment " with separated the propelled wheels from the water. If the water becomes flat, the flotation chambers are brought in ever more, ", until the wheels and their drive take over the Forbewegung.

The new amphibious vehicle makes itself possible it, in the transient area for water - country to induce, independently of that depth of water to the Schraubenoder possible jet drive can be used additionally the wheel drive.

Thus the vehicle can be except genuine anchoring on the water, also on firm reason surely.

Drive on public traffic routes is possible during traffic-optimized execution.

During this special execution it is favourable, if couches, sun screen and most diverse Badeassessoires are integrated.

The increased couch position protects against danger of injury with dangerous underground, in addition, against reptile infestation.

For progressive movement on the water all can be used hiefür usual drive systems, whereby lighter drives become to be preferred are.

Since the wheel drive is often only cure timely used, a lighter is made possible for electric drive with rechargeable batteries, however all usual wheel drives can be used.

With “ashore” the passengers do not go having in the water to rise, whereby possible injuring doing gene in danger places it is prevented and also dangerous water animals, as is e.g. avoided to sea-hedgehogs or Quallen.

The new amphibious vehicle was developed in the special one as kind ship's boat. It is to serve for the easy investigation of nature beautifulnesses lying in the environment, and to make at the same time immediate bath fun possible.

It is naturally primarily conceived for the fair weather employment.

The designs represent a simple version of the new vehicle, which was laid out here in particular as bath vehicle.

In Fig. the side view of the new amphibious vehicle 100 - here trained as Badeund entertainment vehicle - represented 01 with driven out flotation chambers 2 during trip in the water 20 is.

The driven out flotation chambers 2 take over the complete lift of the vehicle 100 including passengers, so that the vehicle trunk 1 inclusive wheels 7,1, 7,2, the passenger compartment and the complete technology above the Wasserlinie 20,1 are. The flotation chambers 2 are downward swivelled in this representation by means of at them and at the vehicle trunk 1 over linking 3,1, 3,2 linked swivel arms 5 of the flotation chamber mechanics 50. The current supply is realized for example with on-board tension.

It would be naturally quite possible, the flotation chambers 2 by means of e.g. linear guidance to drive out for example hydraulically. To consider it is only that the vehicle trunk 1 is to remain in the best possible way waterproof. This is simplest by the swivel arms 5 to ensure. The linking 3,2 at the flotation chamber 2 take over the lagging, so that everyone is the flotation chamber 2 parallel to in each case the different one lowerable and retractable.

The main trunk 1 does not have to be actually completely closed, since the flotation chambers 2 must ensure the entire lift anyhow. Also on damages of the flotation chambers 2 it is favourable to exclude a sinking as their cavity is filled with a sea water-steady foam material.

In this representation the marine propeller 6,1 of the ground connection impulse swung 6 completely into the water 20. In this representation the new amphibious vehicle corresponds for instance a Katamaran, and has in this way the most favorable water resistance.

The Fig. 02 it shows - during otherwise continuous reference symbol meanings - which is vehicle according to invention 100 also here in front view in the water evidently that the main trunk 1 including the wheels 7,1, 7,2 at the vertical steering axle 7,2 completely from the water 20 lifted itself. Further there the katamaranartige, reciprocal lateral arrangement of the two flotation chambers 2 is well evident.

The Fig. - during otherwise continuous reference symbol meanings - a back opinion of the new vehicle 1 O0 shows 03 in the water sterreichisches patent office RK 12,761 U1 2012-11-15 is evident also here that its trunk 1 with longitudinal recessing 13 including the wheels 7,1, 7,2 completely from the water 20 lifted itself. Likewise the marine propeller is 6,1 of the Außenborders (6), which under the Wasserlinie 20,1 are, well evidently.

The Fig. 4, 4,1 and 4,2 shows the new vehicle 100 with the transition of the water 20 to the country 31.

From the Fig. 04 actual with otherwise continuous reference symbol meanings - a side view of the vehicle 100 with ground contact of the pair of front wheels 7,1 with the water reason 30.

There is well the position here the viewer of turned flotation chamber 2 and the Außenborders 6 for the Landgang visible. The flotation chambers 2 brought in completely, Außenborder 6 are so far high-trimmed that the propelling screw 6,1 still in the water 20 is. The cooling of the engine is still ensured. At the same time the marine propeller has 6,1 in addition, sufficiently distance to the water reason.

The Fig. - during otherwise continuous reference symbol meanings - a side view of the vehicle 100 with ground contact Vorderund of rear wheels 7,1, 7,2 shows 04.1 with small depths of water.

The water level is here low enough, so that within this range Vorderund has the rear wheels 7,1, 7,2 ground contact.

Here the flotation chambers 2 do not have to be lowered necessarily, it are thus already safe conditions on the wheels 7,1, 7,2 possible.

The Fig. - during continuous reference symbol meanings - a side view of the vehicle 100 shows 04.2 whereby the flotation chambers 2 with small depths of water ground contact has.

The flotation chambers 2 drove out completely toward downward, and support the vehicle 100 stably at the ground off.

Further maximally up-trimmed Außenborder 6 is recognizable. The water level is however so low that by the lift is however no longer possible for drifts.

The Fig. - during otherwise continuous reference symbol meanings - the new vehicle 100 shows 05 in side view, if it ashore is, whereby the land reason with 31 is characteristic.

A sufficient clearance is given 2 by completely high thus the brought in flotation chambers and by completely Außenborder trimmed still above 6. The clearance sufficient thereby makes possible in this way also trips in the hilly area.

The Fig. - during otherwise continuous reference symbol meanings - the new amphibious vehicle 100 shows 06 in front view on the country, whereby the wheels 7,1, 7,2 have full contact with the land reason of 31 and the Fig.07 shows - likewise with otherwise continuous reference symbol meanings - the new vehicle 100 in Hinteransicht, likewise on the country.

All usual shipbuilding materials, how wood, metal or plastic for the building of the new vehicle are used, can do for the easier production of a prototype mainly aluminum were used.
