FIELD: transportation.
SUBSTANCE: invention relates to off-road vehicles and can be used as wheelchair propulsor for overcoming stair flights of common use. Screw-type propulsor comprises a hollow cylindrical rotor with a screw crest, on which a system of solids of revolution equipped with a drive is installed, and a rotary head. Multistage resilient screw crest support is made in the rotor body. Rotary bodies of the carp spar type are put on the screw crests and fixed on their substrates in the body of the rotor.
EFFECT: broader functional capabilities of screw propulsor wheelchairs for movement on solid surfaces with obstacles.
