Claims (4)
- 선택적으로 전환가능한 이중 탄성률 차량 서스펜션 시스템에 있어서, 상기 시스템은:
차량의 한 코너의 언스프렁 매스와 스프렁 매스 사이에 배열된 푸시로드 작동식 인보드 스프링을 포함하되, 상기 푸시로드 작동식 인보드 스프링은 제1 사전결정된 탄성률 K1의 토션 바 스프링과 제2 사전결정된 탄성률 K2의 코일 스프링을 포함하고, 이들은 직렬로 배열되어 총 조합 탄성률 KT을 제공하며;
코일 스프링과 병렬로 배열된 록아웃 액츄에이터를 포함하되, 상기 록아웃 액츄에이터는, 제1 모드에서 코일 스프링이 자유로이 이동될 수 있고 제2 모드에서는 코일 스프링의 움직임을 방지하도록 구성되며,
록아웃 액츄에이터가 제1의 언로킹 모드에 있을 때에는 차량의 총 서스펜션 탄성률은 급수 공식 1/KT = 1/ K1 + 1/K2에 의해 정의되며, 록아웃 액츄에이터가 제2의 로킹 모드에 있을 때에는 차량의 총 서스펜션 탄성률은 KT = K1에 의해 정의된 것과 같이 실질적으로 더 높아서, 낮은 탄성률의 최적의 탑승 안락성 설정과 높은 탄성률의 최적의 조종 설정을 선택적으로 제공하는 것을 특징으로 하는, 선택적으로 전환가능한 이중 탄성률 차량 서스펜션 시스템. - 제1항에 있어서, 록아웃 액츄에이터는 유압 실린더와 유압 회로를 포함하되, 상기 유압 회로는 제1의 언로킹 모드와 제2의 로킹 모드를 제공할 수 있도록 유압 실린더 내의 두 용적 사이의 연결을 선택적으로 개폐하는 것을 특징으로 하는, 선택적으로 전환가능한 이중 탄성률 차량 서스펜션 시스템.
- 제1항에 있어서, 록아웃 액츄에이터는 유압 실린더와 유압 회로를 포함하되, 상기 유압 회로는 제1의 언로킹 모드와 제2의 로킹 모드를 제공할 수 있도록 유압 실린더 내의 두 용적 사이의 연결을 선택적으로 개폐하며, 유압 회로는, 차량의 탑승 높이가 K1 탄성률 모드에서 결정될 수 있도록, 유압 액츄에이터에 전력을 공급하여 코일 스프링을 구동시켜 사전결정된 위치로 이동하도록 구성되는 것을 특징으로 하는, 선택적으로 전환가능한 이중 탄성률 차량 서스펜션 시스템.
- 제1항에 있어서, 록아웃 액츄에이터는 유압 실린더와 유압 회로를 포함하되, 상기 유압 회로는 제1의 언로킹 모드와 제2의 로킹 모드를 제공할 수 있도록 유압 실린더 내의 두 용적 사이의 연결을 선택적으로 개폐하며, 유압 회로는, K1 탄성률 모드의 차량의 탑승 높이가 1/K1 + 1/K2 탄성률 모드보다 상대적으로 낮게 결정될 수 있도록, 유압 액츄에이터에 전력을 공급하여 코일 스프링을 구동시켜 사전결정된 위치로 이동하도록 구성되는 것을 특징으로 하는, 선택적으로 전환가능한 이중 탄성률 차량 서스펜션 시스템.
