The invention relates to a vehicle is amphibious with a single drive motor, which may lead to selection independently of each other or simultaneously land and men drives.

Vehicles of all sorts are increasingly used in the field of leisure for entertainment purposes. Examples of this are snowmobiles, jet skis or blazemobile, which are made with three or four low-pressure tires and therefore can also move on the sand. A disadvantage of the known vehicles is that each of them can only be used in one environment or they are unsuitable for entertainment purposes. Examples of this are tracked snowmobiles or amphibious vehicles. Known amphibious vehicles for military or civilian purposes are relatively large and shapeless. The reason for this lies mainly in the fact that the lower side of the vehicle simulates the boat hull to provide buoyancy. In other forms of execution attempts are being made to improve conventional cars by modifications such as floating console, and achieved speeds on the water remain unsatisfactory.

From DE 3522041 A1 famous four-wheel drive amphibious with high speed on the water, which due to the position of vane-deflector with the system at all four wheels during movement on the water are high lifting force, which raise the vehicle body from the water. In contact with water leaving only the wheel with blades. Because it is not a particularly high resistance to water, is usually a form of cars amphibious forces, also created a blade system, can give the car a desired high speed on the water. Blade system with their holders Rethimno installed on the wheels when driving on land must be dismantled or prior to operation in a floating regime mounted. Alternatively, the proposed permanent connection between the wheels and blade system. The disadvantages of the known cars amphibians are depending on the form of execution or complex Assembly and disassembly, or the high cost of the device for the automatic pull-out and lower blade system.

From DE 3832559 C1-known car amphibious motor, which leads men drive directly, and overland drive through the transmission, and the transmission ground drive installed clutch, the force which during berthing and movement of water can be changed in accordance with the difference between the actual and predetermined rotation speed of the ground drive with adjustable speed drive up to set. Due to this being the Noah car engine amphibian can work at full speed when landing, so men actuator, which may be in the form of a jet or rocket engine gives maximum traction for facilitating the landing and exit the water.

From DE 3916200 A1 is known a drive unit for a vehicle amphibious, which requires only one drive motor, and, nevertheless, land men and actuators can be used to select independently from each other or simultaneously. Due to this, it is possible that simultaneous operation of the land and men drives only the motor and preferably at a constant engine speed and land-men transmissions can be controlled or adjusted with respect to speed and power independently from each other. This has the great advantage, in particular, when berthing (transition from water to land) and leaving (the transition from land to water), so that, for example, car wheel amphibious not buried in soft coastal soil. For ground drive can be enough only land transmission, and for men actuator - single-men transmissions. If the vehicle is amphibious contains several men of traction devices, such as a few screws or several hydro jet engines, then it is preferable if each of these water is adnych traction device contains its own-men transmission, which you can control or regulate her choice together or independently of each other.

The basis of the invention lies therefore the technical problem of creating a car-amphibious all-terrain, particularly in the realm of leisure, which could, with minimal costs to switch from land mode to floating mode and which in both modes would provide a high enough speed and open the driver's seat.

The technical problem is solved by the characteristics of claim 1 of the claims. Other preferred variants of the invention are given in the dependent clauses.

Due to the Central location of a drive motor center of gravity of the vehicle amphibian may be shifted toward the center of the lifting force so that the center of gravity of the vehicle in a known state is above the center of the lifting force so, basically, not having a torque. Due to this, the vehicle is amphibious, despite an open seat becomes stable position in the water, which generally only now provides an efficient floating mode. Thanks to all-wheel drive car amphibian has a high permeability, and men drive made in the form of a jet drive, provides, on the one hand, sufficient speed through the water, and, the other hand, in contrast to the screw cannot be easily damaged in ground mode, and does not create a risk of injury to third persons.

In another preferred form of execution of the tires of the vehicle amphibious made in the form of low-pressure tires, which, on the one hand, contribute to driving on the sand, and, on the other hand, in a floating mode act simultaneously as creating a lifting force of bodies, and for land mode, the rear low-pressure tires are made mostly little more than the front.

To increase the lifting force in the front and/or rear-amphibians may provide additional discrete, creating a lifting force of the body, performed mostly in the form of air tanks. Using these discrete, creating a lifting force of bodies that can be made with the possibility of dismantling, can, in addition, it is better to set the center of the lifting force.

The invention is explained in more detail using a preferred example of execution.

In the drawing represent:

- figure 1 is a schematic side view of the vehicle amphibious;

- figure 2 is a schematic bottom view of the vehicle is amphibious.

1 shows a vehicle amphibious 1 open seat for two people. The vehicle is amphibious 1 includes a drive motor 2, a gear box 3, the first with whom Alenia 4 for jet actuator 5 and the other two clutch for independent drive of the front 6 and rear 7 wheels. In addition, in the rear of the car amphibian 1 installed air tank 8, and in front of the air tank 9. The drive motor 2 is installed in the center between the front and rear axles under the driver. Due to this, the center 10 of the gravity of its own weight of the car shifts to the front of the driver's seat. A lifting force is created mainly made with low-pressure tires front 6 and rear 7 wheels, and both air tanks 8, 9, can be adjusted by calculation so that the center 11 of the lifting force, the own weight of the vehicle will be located under the driver's seat. Due to the additional weight of the driver and the passenger sitting relatively high, the center 12 of gravity with the full vehicle weight is shifted from one side, up, and, on the other hand, under the driver's seat. Because the center 13 of the lifting force with the full weight of the car moves only upward, the center 12 of gravity and the center 13 of the lifting forces lie on the same line of action, so that there is no resultant torque and the vehicle is amphibious 1 is stable floating position. To improve the hydrodynamics of the air tank 9 is made with a bevel, the top of which concludes with the surface of the water angle α mainly 40°.

Another possibility of increasing the lifting force is, h is usually used to increase the width of the axles of the vehicle amphibious 1 compared to a conventional SUV, for example plausability.

Design and principle of operation of the transmission is illustrated below using the schematic view from below figure 2. Transmissions include installed on the center of the drive motor 2 and box 3 gears that are designed for both the land and for jet actuator 5. Box 3 gear connected to drive shaft 14 with the transfer of 15 front axle, through which are front wheels 6. In addition, the gear box 3 are connected to driven shaft 16 of the transmission 17 of the rear axle, through which by means of a rigid rear axle 18 are both rear wheels 7. For the Department of terrestrial transmission is provided, at least two clutch installed either on the box 3 transmission, or transfer 15 front and the transmission 16 of the rear axle. Both clutch have the ability to control independently from each other. By coupling 4 transmission can be put into engagement with the bevel gear 19 jet actuator 5, and the clutch 4 has the possibility of independent control.

In land mode, the clutch is turned off, and the front 6 and/or 7 rear wheels are driving the engine 2 and the transmission 3 transmission. In floating mode, the clutch 4 include, and the gearing with a bevel gear 19 in rotation is the screw through the hole in Nam who sucks the water and pumps it in the direction of the jet nozzle 20. Popped a jet of water then gives the car amphibian 1 pulse forward movement, on the basis of which the vehicle is amphibious vehicle 1 is driven. Overland transmission may be in a floating mode off or used to support the lifting force. To do this, engage reverse gear, so that the front 6 and rear 7 wheels rotate against the direction of movement. Through independent from each clutch can be provided, for example, only the rear wheels 7. Steering in a floating mode is carried out primarily through the rotary jet nozzle 20, and to support, if necessary, may be involved in steering the front wheels 6. When berthing terrestrial transmission switch back for movement in forward motion, and a driving torque control or regulate it in such a way that the wheels are not buried in the ground. Here you can find application, for example, the device according to DE 3916200 A1.
