Abstract

본 발명은 자동차의 후륜현가에 장착되어 4륜 조향차량의 이루고 있는 후륜조향 장치에 관한 것으로, 특히 차량속도, 전륜조향각 및 요우각속도 등의 함수로서 결정된 후륜조향각에 따라 구동되는 직류모터(10)와, 상기 직류모터(10)의 구동력에 의하여 구동되는 구동기어(20)및 리드 스크류 너트(21)와, 좌,우측에 형성된 유니버설 조인트(31)에 타이로드(31)가 각각 결합되고 상기 리드 쓰크류 너트(21)와 일정한 피치를 가지고 돌아가는 리드 스크류볼트(30)와, 상기 리드 스크류 볼트(30)의 일측에 결합된 커넥터(50)의 상부에 위치하여 리드 스크류 볼트(30)의 병진운동을 따라 움직이는 테이퍼빔(51)과, 상기 테이퍼빔(51)의 상부에 위치하여 상,하로 움직이면서 후륜조타각을 측정하는 위치센서와, 목표조타각과의 오타에 따라 직류모터의 작동을 재 조절하는 전자 제어장치(41)로 구성하여, 신속한 엑츄에이터의 반응을 도모함은 물론 소형화 시켜 차체및 샤시와의 간섭을 방지한 자동차의 후륜조향장치이다.The present invention relates to a rear wheel steering device mounted on a rear wheel suspension of a vehicle and constitutes a four-wheel steering vehicle. In particular, the present invention relates to a DC motor 10 driven according to a rear wheel steering angle determined as a function of vehicle speed, front wheel steering angle, and yaw angle speed. The tie rod 31 is coupled to the drive gear 20 and the lead screw nut 21 driven by the driving force of the DC motor 10, and the universal joint 31 formed on the left and right sides, respectively. The lead screw bolt 30 which has a fixed pitch with the crew nut 21 and the lead screw bolt 30 are located on the upper side of the connector 50 coupled to one side of the lead screw bolt 30 to perform the translational movement of the lead screw bolt 30. The taper beam 51 moving along with it, the position sensor which is located on the taper beam 51 and moves up and down, and measures the rear wheel steering angle, and the front which re-adjusts the operation of the DC motor according to a typo with the target steering angle. It is a rear wheel steering device for automobiles, which is composed of a magnetic control device 41, which facilitates rapid actuator reaction and miniaturizes and prevents interference with the vehicle body and the chassis.
