Known aquatic amphibian vehicles on pneumococus with waterfowl chassis-cab and CP propeller.

The disadvantages of this vehicle amphibious following:

- pretty deep planting amphibians provides great water resistance is, therefore, extremely low speed through the water;

- to increase the speed of the vehicle is amphibious with access to gliding requires excessive increase in engine power, making it more difficult and immersed in water.

Known vehicles, hovercraft, floating through the air screws installed on the roof.

The disadvantage of vehicle:

- the inability to move on the ground with uneven rough surface, except gentle with a small angle of Bank;

- on earth, especially in dry weather, airbag, blowing powdered materials and sand, creates in the circumference of the dust storm;

Known amphibious vehicles hydrofoil and retractable propeller screw (See. A. S. No. 168999 and # 169000, issued on one application No. 648072).

Disadvantages of these vehicles the following:

- increase in vehicle weight due to the presence of underwater wings, retractable propeller, retractable into the body of wheels, transmissions, drives;

- weight transport cf is DSTV due to these funds.

The closest vehicle prototype is a plain machine (car) on wheels.

Disadvantages car on wheels:

- due to the lack of wadatakatoshi protetora and lack of height-adjustable ski car cannot move on the water surface.

The aim of the invention is the provision of movement of the vehicle on the water surface, the speed increase without a substantial increase in engine power.

Semanatoarea motor vehicle contains a waterproof body with high sides, pneumatic wheels with thickened Volosovsky protectors for maximum capture of water availability along with pnevmokolesnymi adjustable height hydraulics water skiing width not less than the thickness of the wheels. With the front of the ski curves so up to provide maximum lifting force of the water drop on a tangent protectors wheels. The number of discarded water per second is the motive power of the vehicle speed and retention on the surface of the water. The main lifting force is achieved by dropping down the lapping of the water layer of the anterior part of the treads of the wheels to the vertical axis, and the other half from the axis vertical. Protectors are vulnerable to negative pressure, consuming part of the rise of the second force. The speed will be characterized and glide vehicle.

What's new is that the tires of the wheels is equipped with Volosovsky and at the same time easily cast tangentially water recessed protectors and a rear wheel, height-adjustable by the amount of clearance skis with pointed toes upward, resulting in a very high speed of the vehicle and hold it on the surface of the water.

Figure 1 shows semanatoarea the vehicle, side view;

figure 2 - tire wheels, in the end;

figure 3 - wheel and water skiing with plots of the proposed water pressure on the protector.

Semanatoarea motor vehicle contains a waterproof cabin with high Board 1, with a flat, smooth, mostly stamped, bottom 2, pneumocytes 3 with reinforced and high vodozabornyjj protectors 4. Behind the wheels are made water-skiing 5 with the hydraulic actuator 6, which should increase the skis on the magnitude of the clearance h. Figure 3 shows a plot of the pressures of 7, which is provided by the main lifting force, plot 8 takes part of the lifting force due to the fact that the force is directed downward and constrains progress.

The linear velocity of the rim protector should be much higher than the speed of the machine to ensure the e driving force by dropping water back. With increasing rotation of the wheels will increase the linear velocity of the rim protector and the less the resistance of the water lapping wheels, but it will increase the air resistance. Therefore, a vehicle with high aerodynamic quality will have a higher velocity.

Technical appraisal and economic benefits are as follows:

- the small and cheap upgrade is to get a new positive quality - the ability of car travel on the water surface on the pneumatic wheels with high speed;

- when the water resistance of a cab-car interior, smooth bottom step of a random stop on the water is not terrible, because the car can go forward on glycerous speed, and then climb on the wheels;

such cars can be widely used to overcome the water frontiers in military Affairs;

you will find a wide use in Oporto, will not refuse motorists, especially the lovers of fishing;

- will be unloaded from the traffic of the road on weekends, public holidays;

- will be reduced operation and loading bridges.

Amphibian vehicle, containing a waterproof case with a smooth bottom, pneumocytes with drive and protectors, characterized in that the tire pneumocolon supply the s Volosovsky protectors, and skis mounted with adjustable angle of attack under a smooth bottom for the wheels and at a distance from them, are adjustable in height to a height clearance of skis and a width of not less than the thickness of the wheels, and the ends of the skis are bent upward, and the front axles of the drive wheels completed the steps.
