Abstract
A vehicle steering system comprises: an input shaft rotatable in response to an input for moving vehicle wheels; a motor generating torque to be supplied to an output shaft through a belt assembly; a gear assembly; a rotary-linear conversion mechanism, and a sector gear; and the rotary-linear conversion mechanism combining rotary motion of the input shaft and the torque transferred from the motor. The torque generated by the motor can be transferred to the output shaft through the belt assembly, the gear assembly, the rotary-linear conversion mechanism, and the sector gear, thereby improving mechanical efficiency, reducing back-drive torque, and providing a multi-stage reduction mechanism to generate required pitman torque from the motor. The combined use of the belt assembly, the gear assembly, the rotary-linear conversion mechanism, and the sector gear enables to the motor to generate required steering torque, while meeting system back-drive performance requirements and current draw power requirements.
