STEERING CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a steering control device for a vehicle with a new mechanism using a ball screw mechanism that can attain further miniaturization. SOLUTION: This steering control device for the vehicle is provided with a first input shaft 1 connected to a steering wheel; a second input shaft 2 connected to a motor 8; an output shaft 3 connected to a steered wheel; a first transmission means 6 for rotating a nut 5 by the rotation of the first input shaft 1 so that the rotation of the first input shaft 1 is transmitted to the rotation of the output shaft 3; and a second transmission means 7 for putting the nut 5 in linear motion in an axial direction to the output shaft 3 by the rotation of the second input shaft 2 so that the rotation of the second input shaft 2 is transmitted to the rotation of the output shaft 3. The center line of the second input shaft and the center line of the output shaft 3 are arranged almost on the same straight line. COPYRIGHT: (C)2004,JPO
