FIELD: transportation.
SUBSTANCE: invention relates to off-road vehicles, and can be used as wheelchair propulsor for overcoming stair flights of common use. Auger propulsor comprises cylindrical rotors with helical flanges with individual reversible rotation drives mounted on double-arm levers at the front and rear of the propulsor. Levers at the front and rear of the propulsor are articulated by a hinge mounted on a rod having a drive to move the rod in a vertical plane, increasing or decreasing the distance between the rotor axes at the front and rear of the propulsor.
EFFECT: broader functional capabilities of screw propulsor wheelchairs for movement on solid surfaces with obstacles.
