FIELD: transport machine building.
SUBSTANCE: invention relates to off-road vehicles and can be used as wheelchair chassis for overcoming by public stair flights of stalls. Screw propulsion unit comprises a hollow cylindrical rotor with a helical ridge, equipped with a rotation mechanism, and a swivel head. Hollow cylindrical rotor for multiturn screw crests is made with holes-slots along helical lines. Kevlar tape is passed through holes-grooves of each helical line. Grousers having holes for belt made of cord-reinforced rubber are mounted on outer part of belt relative to hollow rotor.
EFFECT: use of auger propulsor-chassis of wheelchairs for movement on solid surfaces with obstacles in the form of thresholds, curbs, escarps, including stair flights of common use.
