FIELD: transport engineering. SUBSTANCE: proposed vehicle has screw tracks set into operation by twostroke gasoline engine. Vehicle is provided with common frame on which two aluminum screws with hollow cylindrical part, volume up to 0.15 cu.m are installed on ball bearings. Frame carries adjustable seat of driver, steering column, two-stroke gasoline, engine, fuel tank, friction gearbox with two magnetic friction flywheels, device to control friction flywheels with drive friction clutch, accelerator pedal, magnetic friction flywheels release pedal, flexible drive cables laid from flywheels to screws, engine exhaust system and truck. Drive ferromagnetic friction clutch is secured on engine shaft through speed clutch. Graphine bushings with release turning forks are fitted on shafts of magnetic friction flywheels. Said bushings are coupled with screw shafts by means of flexible drive cables. Accelerator manual control bushing, speed control handle and ignition switch are mounted on steering column which control position of friction flywheels independently. Both screws are covered from by protective aluminum panel. Power output of engine can be 2-3 hp at 3000-3500 rpm. Friction flywheels can serve as attracting permanent magnets, and surfaces of flywheels pointed to side of drive friction clutch can be provided with hard alloy coating. EFFECT: reduced cost of oversnow vehicle, provision of high running speeds and long service life of track. 7 cl, 2 dwg
