FIELD: machine building; transport.
SUBSTANCE: invention relates to transport engineering, in particular to off-road vehicles. Screw-type propulsor comprises a hollow rotor with a screw flange provided with a rotation mechanism and a rotary head. Multi-threaded screw ridge is made on a flexible spring helical auger in the form of a spring – a stylized star in the cross section of the auger, the side-arc of which is directed with its convexity to the hollow shaft.
EFFECT: it is possible to expand the functionality of the screw propulsion in wheelchairs for movement on hard surfaces with obstacles.
