액티브 서스펜션용 유압 액츄에이터의 피스톤 로드 조립구조Piston Rod Assembly of Hydraulic Actuator for Active Suspension

본 고안은 차량의 현가장치(Active Suspension)에 있어 차량이 조향시에도 유압 액츄에이터치 프론트 액츄에이터로 오일을 공급하는 오일공급 호스가 뒤틀리거나 꼬이는 것을 방지하여 오일의 원활하게 공급될 수 있도록 액티브 서스펜션용 유압 액츄에이터 피스톤 로드의 조립구조를 개량한 것이다.The present invention prevents the oil supply hose supplying oil to the hydraulic actuator front actuator even when the vehicle is steered in the vehicle's active suspension to prevent the oil supply hose from being twisted or twisted. The assembly structure of the actuator piston rod is improved.

일반적으로 차량에는 차량이 주행시 차축이 노면에서 받는 진동이나 충격으로 인한 차체와 화물의 손상 방지 및 승차감 향상을 위한 현가장치를 구비하고 있다.In general, the vehicle is provided with a suspension device for preventing the damage to the body and cargo due to the vibration or shock received by the axle on the road when the vehicle is running and to improve the ride comfort.

상기 현가장치는 유압 액츄에이터의 프론트 액츄에이터로 오일을 공급하는 것에 의해 유압 액츄에이터의 감쇠력을 조정하고 있다.The suspension adjusts the damping force of the hydraulic actuator by supplying oil to the front actuator of the hydraulic actuator.

유압 액츄에이터에 오일이 공급되어질 수 있도록 피스톤 로드에 유로를 형성하여 상기 피스톤 로드의 유로를 통해 오일이 공급될 수 있도록 피스톤 로드의 끝단에 오일공급 호스가 접속되는 오일포트 아세이를 조립하고 있다.An oil port assay is formed in which an oil supply hose is connected to an end of the piston rod so that oil is supplied through the oil passage of the piston rod by forming a flow path in the piston rod to supply oil to the hydraulic actuator.

종래에는 피스톤 로드에 오일포트 아세이가 체결 조립되는 일체형으로 구성되고 있어 차량이 조향시에는 오일공급 호스가 뒤틀리거나 꼬이게 되어 오일의 흐름이 원활하게 이루어지지 못하는 등의 문제점이 있었다.Conventionally, since the oil port assay is fastened and assembled to the piston rod, the oil supply hose is twisted or twisted when the vehicle is steered.

따라서 본 고안은 상기와 같은 종래의 문제점을 해소하기 위해서, 액티브 서스펜션용 유압 액츄에이터의 프론트 액츄에이터에 오일을 공급하는 오일공급 호스가 뒤틀리거나 꼬이는 것을 방지함을 그 목적으로 하고 있다.Accordingly, an object of the present invention is to prevent the oil supply hose, which supplies oil to the front actuator of the hydraulic actuator for active suspension, from being twisted or twisted in order to solve the conventional problems as described above.

이하, 첨부된 도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도은 본 고안의 액티브 서스펜션용 유압 액츄에이터의 피스톤 로드에 오일공급 호스가 연결되는 것을 나타낸 일예시도이다.1 is an exemplary view showing that the oil supply hose is connected to the piston rod of the hydraulic actuator for an active suspension of the present invention.

도시된 바와 같이 본 고안은 액티브 서스펜션용 유압 액츄에이터(1)의 피스톤 로드(2) 끝단에 체결구(B)로 체결되는 한 쌍의 후렌지(3:31,32)를 조립하고 상기 후렌지(3)의 내측에 오일공급 호스(5)가 연결되는 회전슬리브(4)가 취부되어 유압 액츄에이터(1)의 피스톤 로드(2)와 오일공급 호스(5)가 연결되는 회전슬리브(4)는 서로 상대되는 회전운동을 하도록 조립되는 구성으로 이루어지고 있다.As shown, the present invention assembles a pair of flanges (3:31, 32) fastened by fasteners (B) to the end of the piston rod (2) of the hydraulic actuator (1) for active suspension and the flange (3) Rotating sleeve 4 to which the oil supply hose 5 is connected is mounted inside the piston rod 2 of the hydraulic actuator 1 and the rotating sleeve 4 to which the oil supply hose 5 is connected to each other. It is made of a configuration that is assembled to rotate.

상기 슬리브(4)와 피스톤 로드(2)에는 오일이 누출되는 것을 방지하는 오링(6)이 개제되고, 상기 슬리브(4)와 후렌지(32) 사이에는 회전을 원활하게 하는 패킹(7)이 삽입되고 있다.An o-ring 6 is provided in the sleeve 4 and the piston rod 2 to prevent oil from leaking, and a packing 7 for smooth rotation is inserted between the sleeve 4 and the flange 32. It is becoming.

상기 오일공급 호스(5)를 통해 회전슬리브(4)의 유로(40)로 공급되는 오일은 피스톤 로드(2)의 유로(20)를 통해 유압 액츄에이터(1)에 공급되고 있다.The oil supplied to the flow path 40 of the rotary sleeve 4 through the oil supply hose 5 is supplied to the hydraulic actuator 1 through the flow path 20 of the piston rod 2.

이러한 구성으로 된 본 고안은 유압 액츄에이터의 피스톤 로드(2)에 한쌍의 후렌지(3)가 조립되고, 상기 후렌지(3)의 내측에 자유로이 회전운동 하도록된 회전슬리브(4)를 개제하여 상기 회전슬리브(4)에 오일공급 호스(5)를 연결하여 피스톤 로드(2)와 회전슬리브(4)가 서로 상대되는 회전운동을 하게 함으로서 차량조향시에도 회전슬리브(4)와 함께 오일공급 호스(5)가 상대되는 쪽으로 회전하게 되어 오일을 공급하는 오일공급 호스(5)가 뒤틀리거나 꼬이는 일이 없게 된다.The present invention having such a configuration has a pair of flanges (3) is assembled to the piston rod (2) of the hydraulic actuator, the rotating sleeve (4) by opening the rotating sleeve (4) to freely rotate the inside of the flange (3). The oil supply hose 5 is connected to the oil supply hose 5 so that the piston rod 2 and the rotary sleeve 4 rotate relative to each other. Is rotated to the opposite side so that the oil supply hose 5 for supplying oil is not twisted or twisted.

따라서 유압 액츄에이터에 오일의 공급 및 흐름이 안정되게 된다.Therefore, the oil supply and flow to the hydraulic actuator is stabilized.

이상에서와 설명한 바와 같이 본 고안은 유압 액츄에이터에 오일을 공급하는 오일공급 호스를 피스톤 로드와 상대 운동하도록 된 회전슬리브에 연결함으로서 조향시에도 유압 액츄에이터의 프론트 액츄에이터에는 오일이 안정되게 공급되는 등의 효과가 있다.As described above, the present invention connects the oil supply hose for supplying the oil to the hydraulic actuator to the rotary sleeve that is relatively moved with the piston rod, so that the oil is stably supplied to the front actuator of the hydraulic actuator even during steering. There is.
