The invention relates to the production of propulsion of wheeled amphibians, intended for transportation of people and goods by land and water surfaces.
Wheeled amphibian waterproof body car, boat or pontoon type equipped with two propellers. For movement on land as amphibious propulsion uses a driving wheel motor of the type which is connected to the body by means of charms. Such a thruster is contained in the labour movement the main engine amphibian with the transmission. To overcome water obstacles on the underside of the vehicle is amphibious, in a special niche, is propeller or water jet, which are contained in the labour movement through additional transmission main or auxiliary engine amphibian.
The combined presence of two different types of propulsion devices with two transmission systems in one wheeled vehicle complicates the manufacturing process the manufacture of amphibians and professional service, poses a risk to the operational viability of the propeller and jet propulsion in operation amphibians on roads with a coating of low quality and contaminated or shallow water bodies with rough or rocky bottom surface of the ground.
The invention excl which includes the above-mentioned disadvantages, inherent in the existing on a technical level, the device is wheeled amphibians.
The invention is aimed at equipping all types of wheeled amphibians universal wheeled vehicles, comprising all the propulsion properties of automotive wheels, propeller and jet propulsion in a single compact, multi-functional unit.
The technical result of the invention improves (makes present) the design, simplifies the design and improves operational survivability wheeled amphibians.
Analogue of the invention for the device, but not on purpose, can serve as a centrifugal impeller pump (fan) to move air or gas, which is used for ventilation of the space, creating a draught in the furnace devices, ventilation and cooling of the heated units (radiators, condensers, motors, and so on). Cm. "A brief Polytechnical dictionary" Professor Y. A. Stepanova, page 136, Gosizdat technical-theoretical literature, Moscow, 1956
Centrifugal impeller pump (fan) includes a rotor with radial blades on it. The rotor rotates in ulitmatebet casing (housing). Air is drawn in through the inlet hole located on the side surface of the casing, keen and discarded due to the centrifugal forces of the rotor blades in the region of idealnoi surface of the housing, where is unwound, and having met in its path outlet, made in the form truncatetable channel, is thrown through it under high pressure in the surrounding space or continues the path for connected the pipeline in a given direction.
The essence of the invention lies in the fact that the rotor of the device similar to the device of the centrifugal impeller pump, located inside the rim of the drive wheel amphibians, rotor blades replaced on the blades of the propeller, and oligopoly casing is installed and fixed on the suspension that connects the drive sprocket amphibians with her body.
The essence of the claimed device wheel mover amphibians is that spokes connecting the hub with the rim of the drive wheel amphibians made in the form of propeller blades, and the shroud mover with oligopotent circuit including input and output holes, installed on the suspension of the drive wheel amphibians and fixed so that its inlet opening, having a diameter close to the size of the diameter of the wheel rim, close to the wheel rim, with a minimum gap, and the hole made in the form of a tubular channel maximized (aims) in feed, Wake side of amphibians.
The drawings depicted the rim 1, the hub 2, the blade 3, the suspension 4, the casing 5, the inlet d1, the output of the slot d2, truncatetable channel 6 and the brake disk 7.
In Fig.1 shows a General side view of amphibians.
In Fig.2 depicts the water-jet node wheeled propulsion amphibians, side view.
In Fig.3 is a perspective bottom view of amphibians with two leading wheels when its wheel thrusters operate amphibians on water. The arrows indicate the direction of movement of the working flow of the water.
In Fig.4 is a perspective bottom view of the amphibious four-wheel drive in the moment of its maneuvering on the water with the front pair of wheel movers. The arrows indicate the direction of movement of the working flow of the water.
In Fig.5 is a perspective bottom view of amphibians with four driving wheels at the time of braking on the water or when maneuvering in the back (aft) direction.
Wheeled mover performs the movement of amphibians on earth in the traditional mode of motor drive wheel. Wheel propeller rotating in the earth, brings amphibian, for example, to the river, plunges its waterproof, has a positive buoyancy of the body in the water and, without stopping, spinning in the water. Rotating in the water, the blades 3 of the propeller located in the opening between the hub 2 and the rim 1 of the wheel propulsion, start raking in the water mass, guiding them through the gap between the rim and brake the claim 7 of the wheel, then through the inlet d1 inside the casing 5, where the water due to centrifugal forces, with the help of blades of the propeller, pressed and raskruchivayas around the radial surface of the housing, gaining speed, meeting on his way truncatetable channel 6, rushes to him and under pressure, in the form of a jet through the opening d2 is thrown in the aft (Wake) direction (see Fig.2). So, using water-jet effect, wheeled mover performs the movement of amphibians, for example, to the opposite shore of the river. Amphibian, breaking the water flow with a rotating wheel propulsion comes ashore and continues its path in a given direction.
Management amphibious propulsion is carried out on the land and on the water traditional automotive way. Speed control using the throttle, adjusting the flow of fuel into the cylinders of the internal combustion engine or other power supply, for example electric, the electric motor of the electric vehicle is amphibious. Management and direction of travel on land and on the water by turning the wheels with the steering device. In the case when the rotary wheel are leading the drive and converted into a universal wheel drives, motion control amphibians on water becomes more efficient (see Fig.4). Back on the water for the implementation of the is, as on earth, by switching the direction of rotation of the wheel movers amphibians in the opposite direction (see Fig.5). In the same way, switch the direction of rotation of the wheel movers on the opposite is the damping rate amphibians up to its full stop on the water.
When sealing and balancing positive buoyancy, most of the models of cars can be turned into amphibians, without breaking the circuit model design (see Fig.1) the body of the device.
Wheel propulsion amphibians, including the rotor blades and the casing with an inlet and outlet, wherein the rotor is constructed inside the drive wheel, which is attached to the body of the amphibian with the suspension, the wheel spins in the role (function) of rotor blades made in the form of propeller blades, the casing is installed and fixed to the suspension of the wheels in the position in which its inlet, is made with a size close to the size of the diameter of the wheel rim, close to the wheel rim, with a minimum gap, and the guide channel of the outlet is turned in the direction of feed, Wake direction amphibians.
