In the design of cross-country vehicles, the designers decided to achieve outstanding results, as a rule, are forced to use unconventional solutions and schemes. Sometimes, when it is possible to create a totally unique all-terrain vehicles, which are capable to impress anyone.

ATV, the movement of which is carried out by means of auger-rotary propeller. The design of the propulsion unit consists of two Archimedes screws of highly durable material. ATV has a unique cross in mud, snow and ice, but is usually not suitable for driving on asphalt or concrete. Screw Rotary movers rover cause great damage to nature. © Wiki

Screw-propelled vehicle DAF Amphirol, built in 1966. On land developed up to 35 km / h, and could swim. This was equipped with a V-belt shnekohod variator

This machine is part of the search-and-rescue complex terrain "Blue Bird", issued between 1980 and 1991 in a limited edition of 20 pieces in all. The complex was designed and built by the Special Design Bureau (SKB) ZIL commissioned by the Chief Designer of rocket and space programs SP Queen, and was intended for search and evacuation of astronauts, lander that landed in an inaccessible for any other vehicle location.

The design of the amphibian is widely used aluminum alloys, which are produced from the carrier system and rotary snow movers and fiberglass - to design 3-seater cockpit, cargo and engine compartments. In the back of the ZIL-4904 established two engine ZIL-375 with a capacity of 180 liters. c., each packaged with hydromechanical 3-speed transmission. Developing their efforts summed reversing transfer box, which by means of drive shafts transmit torque to the final drive, and from it - to the friction and the 2-stage final drives. Turning control driver performed by cutting friction clutches and decelerating (by a band brake) one or the other side. Propelling formed as hollow cylinders with diameter of 1200 mm and welded to the outer surface of the lug with the helical rib helix angle 34 °.

Impressive weight and size SUV sizes: length - 8, 3 m, width - 3, 6 m, height - 3, 44 m, the curb mass of about 8 tons.

Lifting machines was 2, 5 tons, the crew of the machine consisted of four people, the cabin housed four beds. Shnekohod tested for water, swamps, splavninah overgrown with high reeds and bushes, on hard surfaces. On the highway terrain vehicle transported on a specially designed three-axle trailer. However, because of the large size and weight of the use of ZIL-4904 as a search-and-recovery vehicle considered unwise.

To the place of all-terrain vehicle is delivered to the ZIL-4906. With the improvement of the index was 29061.
