Abstract

4륜 조향 시스템에서 엔진 시동오프시 후륜이 항상 직진상태를 유지할 수 있도록 하기 위하여, 조향각 센서(20)로부터 조향유무 상태의 독출 신호를 전달받는 전자제어 유닛(ECU)과, 상기한 전자제어 유닛의 출력단에 전기적으로 연결되어 제어되는 전동 모터(14) 및 전동 클러치(12)와, 상기한 전동 클러치(12)로부터 동력을 선택적으로 전달받는 피니온 기어(8) 및 이 피니온 기어가 치차물림되는 랙기어(6)와, 상기한 랙기어(6)를 보유하고 있으며 각각 좌우후륜으로 조향력을 전달하는 타이로드(4)를 포함하여 이루어지는 차량용 4륜 조향 시스템의 후륜 직진정렬장치.In order to ensure that the rear wheel is always in a straight state at the start-off of the engine in the four-wheel steering system, the electronic control unit (ECU) receiving the read signal in the presence or absence of a steering state from the steering angle sensor 20, The electric motor 14 and the electric clutch 12 electrically connected and controlled to the output end, the pinion gear 8 which selectively receives power from the electric clutch 12, and the pinion gear are toothed. A rear wheel alignment device for a four-wheel steering system for a vehicle, comprising a rack gear (6) and a tie rod (4) having a rack gear (6) and transmitting steering force to the left and right rear wheels, respectively.
