Abstract

본 발명은 차체와 서스펜션아암 사이에 설치되어 압축공기의 유입 및 배출에 의해 차체 높이를 조절하는 에어스프링을 구비한 공기식 현가시스템의 차체높이 다중 조절장치에 관한 것으로서, 정역회동 또는 상,하 이동 또는 좌,우 이동에 의해 상기 압축공기의 유입 및 배출을 단속하는 기계식 레벨링밸브와; 상기 레벨링밸브를 상기 압축공기의 유입 및 배출방향으로 구동시키는 밸브구동기와; 상기 밸브구동기의 구동을 제어하는 제어기를 포함하는 것을 특징으로 한다. 이에 의해, 간단한 구조로 차체의 높이를 사용자가 필요에 따라서 원하는 대로 조절할 수 있고, 장치의 가격이 저렴한 공기식 현가시스템의 차체 높이 다중 조절 장치가 제공된다.
