Abstract

조향륜의 완전 조향시에만 후륜이 조향되도록하여 회전반경을 최소화할 목적으로; 스티어링 휠의 조향방향에 따라 주펌프로부터 송출되는 유압을 선택적으로 제어하는 전륜 방향제어밸브와; 상기 전륜 제어밸브로부터 공급되는 유압에 의하여 동작되면서 전륜의 조향이 이루어지도록 하는 전륜 동력실린더와; 상기 전륜 동력실린더의 양측으로 배치되어 해당 실린더측으로 최대한의 유압이 공급될 때 좌, 우 압력센서로부터 신호를 받는 전자제어유닛과; 릴레이를 개재시켜 상기 전자 제어유닛에 의하여 제어되면서 정, 역회전하는 정, 역회전 모터와; 상기 정, 역회전 모터의 피니언과 치합되어 이의 구동에 따라 동작되면서 후륜의 조향이 이루어지도록 하는 랙을 포함하여 이루어지는 자동차의 회전반경 최소화 시스템을 제공한다.To minimize the radius of rotation by steering the rear wheels only when the steering wheel is fully steered; A front wheel direction control valve for selectively controlling the oil pressure transmitted from the main pump according to the steering direction of the steering wheel; A front wheel power cylinder which operates by hydraulic pressure supplied from the front wheel control valve and enables steering of the front wheels; An electronic control unit arranged at both sides of the front wheel power cylinder and receiving a signal from the left and right pressure sensors when the maximum hydraulic pressure is supplied to the cylinder side; A forward and reverse rotation motor controlled by the electronic control unit via a relay to rotate forward and reverse; Provided with the pinion of the forward, reverse rotation motor is operated in accordance with its driving to provide a system for minimizing the rotation radius of the vehicle comprising a rack for steering of the rear wheels.
