The present invention relates to a cylinder device for a suspension of a vehicle and, more specifically, to a cylinder device which can prevent a vehicle from being overturned using an auxiliary cylinder which is locked without contraction when a hydraulic pressure of a main cylinder supporting a suspension leaks. According to the present invention, when a hydraulic pressure of a working cylinder included in a main cylinder leaks and contracts arbitrarily, a locking cylinder is locked without contraction as the hydraulic fluid circulation in the locking cylinder included in an auxiliary cylinder is blocked by a locking member to provide a support power and prevent a suspension from being tilted and a vehicle from being overturned.

    본 발명은 차량용 서스펜션용 실린더장치에 관한 것으로, 더욱 상세하게는 서스펜션을 지지하는 메인실린더의 유압이 누설될 경우 수축이 방지된 상태로 록킹되는 보조실린더를 통해 차량의 전복을 방지할 수 있는 실린더장치에 관한 것이다. 본 발명에 따르면, 메인실린더를 이루는 워킹실린더의 유압이 누설되어 임의로 수축될 경우, 보조실린더를 이루는 록킹실린더의 작동유 순환이 록킹부재에 의해 차단되면서 록킹실린더가 수축이 방지된 상태로 록킹됨에 따라 지지력이 제공되므로 서스펜션의 기울어짐과 나아가 차량의 전복을 방지할 수 있다.
