Abstract
Description
Claims (4)
- 로어암와 차체의 장차부위에 유압부시를 설치하고, 상기 유압부시에 유압을 공급하는 유압원과, 공급되는 유압을 제어하는 제어밸브와, 차량의 주행상황에 따라 전기적인 제어신호를 유압제어밸브에 인가하는 전자 제어장치가 구비되는 것에 있어서, 2개의 비례압력 제어밸브를 이용하여 유압부시의 상·하 유체실의 압력을 제어하여 유압부시의 위치 및 강성(Stiffiness)을 제어하는 것을 특징으로 하는 자동차 서스펜션용 유압부시 제어장치.
- 제1항에 있어서, 상기 유압부시(40)는 부시외통(401), 부시내통(403), 외통과 내통사이의 고무 탄성체(402) 및 탄성체내에 서로 대칭으로 설치된 유체실(404, 405)과, 이 유체실(404, 405)에 외부로부터 유압유를 공급 및 배유시키기 위하여 외통부에 유압용 피팅(406)을 장착한 구조로 되는 것을 특징으로 하는 자동차 서스펜션용 유압부시 제어장치.
- 제2항에 있어서, 유압부시(40)의 각 유체실(404, 405)에 유압을 공급하기 위한 유압시스템의 유압 공급원은 오일탱크(100), 유압펌프(60), 유압펌프를 구동시키기 위한 동력원(70), 시스템 이상시 유압회로를 보호하기 위한 릴리프 시킬 수 있는 릴리프 밸브(64)로 구성됨을 특징으로 하는 자동차 서스펜션용 유압부시 제어장치.
- 제3항에 있어서, 상기 유압부시(40)을 제어하기 위한 제어장치는 차속센서(91), 조향각 센서(92)로부터 차량의 주행상태를 감지한 후 비례압력 제어밸브(60, 61)에 전기적인 명령신호를 내어보내는 전자제어장치(90)를 포함하는 것을 특징으로 하는 자동차 서스펜션용 유압부시 제어장치.
