The present invention relates to an automotive rear wheel steering apparatus. The present invention relates to a technique for securing constant centering restoration force while improving driving stability through a rear wheel centering function. The present invention comprises: a torsion bar spring fixed to a rear axle; a variable gear ratio structure provided so as to be connected to the torsion bar spring, wherein torque generated through twisting of the torsion bar spring varies in accordance with a change in a gear ratio and is constantly output; and an idler arm coupled to a portion of one end outputting the torque through the variable gear ratio structure and the other end connected to the rear wheel via a tie rod and rotated in correspondence to the steering direction of the rear wheel around one end.

    본 발명은 후륜 센터링 기능을 통한 주행 안정성 향상과 함께 일정한 센터링 복원력을 확보하는 기술에 관한 것으로, 본 발명에서는 리어액슬에 고정된 토션바스프링; 상기 토션바스프링과 이어지도록 마련되어, 토션바스프링의 비틀림을 통해 생성되는 토크가 기어비의 변화에 따라 가변되어 일정하게 출력되는 가변기어비구조; 및 일단이 상기 가변기어비구조를 통해 토크가 출력되는 부분과 결합되고, 타단이 타이로드를 매개로 후륜에 연결되어 일단을 중심으로 후륜의 조향방향에 대응하여 회전되는 아이들러암;을 포함하여 구성되는 차량용 후륜 조향장치가 소개된다.
