Filed: 1995-06-30
Abstract: PURPOSE: To downsize a steering shaft by providing an electric motor for the power steering on an electric power steering gear on the power transmission rear side to prevent the excessive torque on the steering shaft of the thickness to the absolute minimum. CONSTITUTION: When a steering wheel is turned, a main worm shaft 24 is turned through an intermediate shaft, and a control device receives the signals from a steering sensor and a vehicle speed sensor, drives an electric motor 26, and turns an assist worm shaft 25 by its power. A ball nut 22 is reciprocated straight on the worm shafts 24, 25, and a pit man arm 23 is oscillated through the engagement of a rack gear 22a and a sector gear 23b.
