According to the definition wikipedia propeller or skeletal-way element is a device that converts the energy of the engine, or external source into useful work to move the vehicle from which the most common: the wheel and gusinitsy (trucks), then the exotic: airbag and screws, the latter is the main focus of my creative transformation. 

 

 

Shnekohod first invented in 1868 by Jakob Morato, 

 

in Russia, shnekohod referred to as 1900, when the Russian inventor F. Dergintu was awarded a patent on a similar technical solution and that's after more than a century, the author of this article tries to prove that the screw-rotor propeller did not reveal its full potential and, based on designs new loco-way element Tesch drive that will be needed to build amphibious platforms and special vehicles naznacheniya.Vidimo the main driving force for innovative ideas towards the development of various off-road systems in our country began its vast and poor roads, and places them full absence. 

, So the screw, as shown in the figure represents a cylinder with a welded spirals Archimedes vintov.Takih shnekohoda cylinders in two, and Witów wrapped blade-sided, ie one clockwise, the other protiv.K main advantages of the screw-propeller rotor may include a combination of properties of the float and propeller, allowing it to fine coping with aquifer soils and boost water obstacles come ashore anywhere, easily coping, due to their high groundwater zatsepnyh properties with steep slopes Coast linii.No and the rate of movement of these ATVs low-up to 20 km / h and energy costs are enormous, and the energy expended just for loosening the soil and it makes it impossible to move the screw-rotor technology on public roads. 

 

Perhaps the most well-known machine of this type ZIL-2906, part of the search and rescue complex "Blue Bird", intended for the evacuation of astronauts from remote areas of planting. By job ZIL-2906 brought on board six-wheel all-terrain vehicle. Tandem wheels and screw worked by the following scheme, when road conditions deteriorate so much that does not allow further peremeschatsya core, wheeled platform, then landed on the ground shnekohod and he is sent to the destination on the soft ground, and after the task is returned to the main wheel machine. The concept of transformable worms Tesch Drive is the union of the wheel and the screw propeller on one rame.Dlya in this space interturn screw-rotor placed element with variable geometry, rubber hose, which in the expanded state takes the weight of the vehicle, allows him to engines in the mode of rolling and is the primary operating mode Tesch Drive until the road conditions allow. When on the road all-terrain obstacle appears in the form of water-bearing, loose soil Tesch Drive is transferred to the screw mode, a decrease of interturn element of air (fluid) vypuskaetsya.Transportnoe tool in this mode permeschaetsya "sideways." In the case of a narrow road with poor soils in screw mode, you will peremeschatsya and zig-zag path, until the vehicle vydet into the open, or until the bottoms do not become more dense and can be re-transfer to the regime kacheniya.V percentage while driving in a screw mode takes gorazdno smaller share than kachenie.Rassmatrivaetsya as pneumatic and hydraulic circuits convert interturn elementa.Pri isteranii element is replaced by new, and this procedure is possible and in the field. System management extension-compression sleeves can be placed inside rotorov.Eto important for hydraulic circuits, where as the working medium instead of air advocates fluid and the angular velocity of rotation of the rotors nevelika.Po my idea of hydraulic circuit will reduce the time needed for translation Tesch Drive from one operating mode drugoy.Dlya pneumatic version of the compressor will be placed on a frame vehicle sredstva.Vypusknoy valve inside, everything is controlled electronically. 

 

Prototype aluminum should priznatsya that this is not the most successful material for this kind nagruzok.No for a visual aid that reflects the basic elements of design is quite podhodyasch.Privoda two drills at 1.2 kW, rather weak to work in a screw rezhime.Nu as a whole showed launches important thing is that fundamentally this line-up of the vehicle is possible, but requires a lot of design raboty.V mode wheel model moves without deviation from the straight linii.Byli changes that it will divert water into storonu.Na design showed high plavuchest.I that pumped that with deflated balloons velocity is almost one and the zhe.Da, really, for a transfer Tesh of the wheel in the screw and back there is a question of folding excess length hoses for blowing. This element is the main battle field of design thinking that has vperedi.Sam transformation Tesh mode mode for heavy vehicles, with two pairs of screw-rotors, should be fully avtomatizirovan.Dlya this as a possible variant, the sleeve is divided into two halves and Special drive placed inside the rotor, stretch their ends, in a deflated state, toward each drugu.Takim way empty hoses clamped to the body rotora.V active phase when they are filled with compressed air, extending form the "rollers" on the edges of the screw-rotor . For light vehicles, this operation may be executed and vruchnuyu.Protektor, the entire length of the sleeves, with a certain step is provided with loops and kryuchkami.Operator, with a special lever, connects them with each other, thereby pressing the empty sleeve of the rotor that it mimnimaliziruet iznos.Pri work Tesh in screw mode for passing irregularities frame is equipped with folding wedge-shaped buffers, either on the rotor operator mounts the spiral cone. As the tread can be used Kevlar, titanium screw-rotors. Then you should pay attention to the fact that the vehicle is in screw mode, moving only watered soils, or in crossing the water pregrady.V the first case the water serve as lubricant, which considerably reduces abrasion in the second case the friction minimalno.V end opportunity peremeschatsya Tesch Drive remains even if both cylinders are punched, allowing him to leave the danger zone under its own power, which is not true, for example, gusinichnom drive, in which case the lost maintain the integrity of truck immobilizes mashinu.Opisyvaemomu technical solution could be defined as all-weather, fully amphibious propulsion. Now you have to compare it with the nearest competitor. Truckee and the wheel of this definition is clearly not fit, cut truck and postavte its water-utonet.Hotya he was trying to teach him to swim, but bezuspeshno.Koleso did not sink, but without the extras are not as rabotatet vodomet.Ostaetsya only one unit appropriate under this definition is a platform to air podushke.Oni really go and Serious Drought and water, but can you name them all-weather? No ... If a strong wind, these vehicles remain at home, whether they prikole.Mogut peremeschatsya in the city, just do not have a very weak upravlyaemost.Vyvod one that is completely self-contained, amphibious propulsion, are not susceptible to weather conditions at the propeller segodneshny day is simply not suschestvuet.Kak author believe that Tesch Drive is able to occupy this niche and because of the unique opportunities that it provides a justifiable and costs associated with its development and use of technology izgotovleniem.S "transformable worms," perhaps the creation of transport systems for various applications, both civilian and military.
