Abstract
A power assisted steering system provides a gear reduction between a steering wheel and a steering mechanism and a much larger gear reduction between an electric motor and a steering mechanism. The system is back-driveable from the steering mechanism. The system utilizes a ball-screw, several helical gears, and two bevel gears. A rack fixed to the ball-screw nut drives a sector gear.
