STEERING CONTROLLER OF VEHICLE

摘要

A steering controller of vehicle having a novel mechanism employing a ball screw mechanism in which the size can be reduced furthermore. The steering controller of vehicle comprises a first input shaft (1) being coupled with a handle, a second input shaft (2) being coupled with a motor, an output shaft (3) being coupled with a steering wheel, a first transmitting means (6) for rotating a nut (5) through rotary motion of the first input shaft (1) so that rotary motion of the first input shaft (1) is transmitted to the output shaft (3), and a second transmitting means (7) for moving the nut (5) linearly in the axial direction with respect to the output shaft (3) through rotary motion of the second input shaft (2) so that rotary motion of the second input shaft (2) is transmitted to that of the output shaft (3). Center lines of the second input shaft and the output shaft (3) are substantially aligned.
