차량 휠 조립체들의 서스펜션들을 위한 유공압 시스템(51)에는 각각의 서스펜션을 위해, 서로에 대해 축방향으로 이동하고 피스톤 요소(30)를 통해 서로 축방향으로 분리된 각각의 챔버들(14, 15)을 정의할 수 있는 제1 및 제2 몸체(10,11)를 갖는 각각의 유공압 실린더(1)가 제공되고; 피스톤 요소는 제2 몸체(11)에 유밀 방식으로 결합되고 2개의 챔버들(14, 15) 내의 압력들에 응답하여 2개의 스트로크 단부 위치들 사이에 부유하고; 각각의 유공압 실린더(1)의 2개의 챔버들(14, 15)은 유압 공급 라인(52) 및 공압 공급 라인(57)과 각각 연통하고; 시스템(51)은 공압 공급 라인(57) 내의 압력을 유압 공급 라인(52) 내의 압력과 적어도 동일한 값으로 설정하는 가압 장치를 더 갖는다.

    A hydropneumatic system (51) for suspensions of vehicle wheel assemblies is provided, for each suspension, with a respective hydropneumatic cylinder (1) having a first and a second body (10,11), which can move axially relative to each other and define respective chambers (14,15), axially separated from each other via a piston element (30); the latter is coupled in a fluid-tight manner to the second body (11) and floats between two stroke end positions in response to the pressures in the two chambers (14,15); the two chambers (14,15) of each hydropneumatic cylinder (1) communicate respectively with a hydraulic supply line (52) and with a pneumatic supply line (57); the system (51) further has a pressurization device which sets the pressure in the pneumatic supply line (57) to a value at least equal to the pressure in the hydraulic supply line (52).
