FIELD: transport engineering.
SUBSTANCE: invention relates to off-road vehicles, and can be used as a propulsion unit and chassis of wheelchairs to overcome the last flights of stairs for general use. An auger propulsion unit contains a hollow cylindrical rotor with a helical ridge, provided with a rotation mechanism, and a swivel head. The multi-threaded helical ridge is made in the form of a system of cylindrical rings made of tubular elastomeric material, mounted and fixed in the transverse grooves of the hollow cylindrical rotor to a depth of not more than half of its diameter.
EFFECT: simplification of manufacturing technology and expansion of the functionality of screw propellers in wheelchairs during movement.
