Claims (7)
- 운전대(1),조종을 위해 상기 운전대와 완전하게 연결되고 조종가능한 차량휠들,조종가능한 상기 차량휠들 및 운전대와 완전하게 연결되는 복도식 유압서보모터(4),유압을 발생시키는 유압발생장치,상대적으로 유압이 없는 저장용기(12),상기 유압서보모터(4)의 양쪽 측부들에 연결될 수 있고, 두 개의 평행한 3위치식 감압밸브(7,8)들의 배열이 구성되고, 상기 감압밸브(7,8)들이 연결라인(5,6)에 연결되며,조종가능한 차량휠들 및 운전대(1)사이에서 전달되는 토크 또는 하중을 감지하기 위한 토크센서(16),운전대(1)에서 감지될 수 있는 운전자의 적용하중을 감소시키기 위하여, 상기 유압서보모터(4)가 부스팅하중을 발생시키도록, 조종가능한 차량들 및 운전대(1)사이에 전달되는 토크 또는 하중이 함수로서 상기 감압밸브(7,8)를 제어하고, 입력측에서 상기 토크센서(16)와 연결되는 전자제어장치(15)가 구성되는 유압파워스티어링시스템에 있어서,상기 유압발생장치가 축압기(11)를 가지고,상기 감압밸브(7,8)가 제어가능한 목표압력값을 가지며,상기 감압밸브(7,8)들의 목표압력값을 제어하여 상기 감압밸브(7,8)가 제어되는 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 상기 감압밸브(7,8)가 비례제어밸브인 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 축압기(11)로 역류의 발생을 방지하는 역류방지밸브(9,10)가 감압밸브(7,8) 및 축압기(11)사이에 배열되는 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 작동방해장치로서 유압서보모터(4)의 유압작동을 방해하는 상태가 상기 전자제어장치(15)에 의해 설정되는 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 매개변수의 함수로서 변환되는 목표압력값이 상기 전자제어장치(15)에 의해 미리 결정되는 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 전자제어장치(15)에 의해 제어되는 스프링(20)의 하중에 의해 감압밸브(7,8)들이 연결라인(5,6)의 압력에 대해 가압되어, 축압기(11)를 연결라인(5,6)에 연결시키는 위치로 상기 감압밸브들이 가압되는 것을 특징으로 하는 유압파워스티어링시스템.
- 제 1항에 있어서, 전기공급으로 구동되고 상기 전자제어장치(15)에 의해 작동되는 펌프(13)에 의해 상기 축압기(11)가 연결되는 것을 특징으로 하는 유압파워스티어링시스템.
