일반적으로, 차량에는 주행상태에 따라 발생하는 진동을 억제하여 차량이 최대한 수평을 유지하게 하여 승차감 향상을 도모하고, 선회 및 조향시에는 각 액츄에이터를 제어하여 차량자세제어 및 조종·안정성을 개선하기 위해 연속가변형 댐퍼 액츄에이터를 구비하고 있다.In general, in order to improve the riding comfort by suppressing the vibration generated according to the driving state to keep the vehicle as horizontal as possible, and to control each actuator during turning and steering, to improve vehicle posture control and steering and stability. A continuously variable damper actuator is provided.

이러한, 종래의 연속가변형 댐퍼 액츄에이터는 댐퍼 액츄에이터 샤프트에 연결되는 콘트롤로드에 의해 댐퍼의 감쇠력을 제어하는 것으로, 도 1에 도시된 바와 같이, 댐퍼 액츄에이터에 의해 댐퍼의 감쇠력을 제어하는 것으로, 도 1에 도시된 바와 같이, 댐퍼 액츄에이터 하우징(1)에 장착된 엑츄에이터 샤프트(2)의 선단에 중공체로 되는 댐퍼로드(3)의 내측으로 설치되는 콘트롤로드(4)의 선단이 끼워지도록 설치된다.Such a conventional continuously variable damper actuator is to control the damping force of the damper by a control rod connected to the damper actuator shaft. As shown in FIG. 1, the damping force of the damper is controlled by the damper actuator. As shown, the tip of the control rod 4 installed inside the damper rod 3, which is a hollow body, is fitted to the tip of the actuator shaft 2 mounted to the damper actuator housing 1 so as to fit therein.

하지만, 종래에는 콘트롤로드(4)가 수용되는 댐퍼로드(3)의 한쪽 끝단을 하우징(1)의 커버(10)에 관통되게 밀어 넣은 후 커버(10)에 댐퍼로드(3)가 고정되도록 너트(12)를 체결한 다음 콘트롤로드(4)의 선단이 엑츄에이터 샤프트(2)에 끼워지도록 설치함으로써 콘트롤로드(4)와 엑츄에이터 샤프트(2)의 중심이 일치하지 않아 설치에 어려움이 있었다.However, in the related art, one end of the damper rod 3 in which the control rod 4 is accommodated is pushed through the cover 10 of the housing 1, and then the nut is fixed so that the damper rod 3 is fixed to the cover 10. (12) and then the front end of the control rod (4) is installed to be fitted to the actuator shaft (2) by the center of the control rod (4) and the actuator shaft (2) did not coincide, there was a difficulty in installation.

그리고, 이를 개선하기 위해 종래에는 도 2와 같이 너트(12)에 별도의 조립 가이드(12)를 형성하여 이 조립가이드(120)가 엑츄에이터 샤프트(2)가 설치된 부싱(5)의 하부 주연으로 끼워질 수 있게 하여 콘트롤로드(4)와 엑츄에이터 샤프트(3)의 중심이 일치시키는 방법이 이용되기도 하였다.In order to improve this, conventionally, as shown in FIG. 2, a separate assembly guide 12 is formed on the nut 12, and the assembly guide 120 is inserted into the lower periphery of the bushing 5 in which the actuator shaft 2 is installed. In some cases, a method in which the center of the control rod 4 and the actuator shaft 3 coincide with each other has been used.

그러나, 이러한 종래의 엑츄에이터는 부싱과 너트가 각각 분리 형성되어 있고, 이를 하우징 내부의 좁은 공간에 설치해야 하므로 그 설치하는 공정이 복잡하게 된다. 특히 작은 크기로 마련되는 너트는 별도의 고정부재 없이 하우징의 내부에 설치되므로 그 설치위치를 정하는데 많은 불편한 문제점이 있었다.However, in the conventional actuator, the bushing and the nut are separately formed, and they must be installed in a narrow space inside the housing, which makes the installation process complicated. In particular, the nut provided with a small size is installed inside the housing without a separate fixing member has a lot of inconvenience to determine the installation position.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 엑츄에이터의 하우징 내부에 설치된 부싱과 댐퍼로드를 직접 연결하여 하우징에 댐퍼로드가 용이하게 고정되는 연속가변댐퍼의 엑츄에이터를 제공하는 것이다.The present invention is to solve the conventional problems as described above, an object of the present invention is to directly connect the bushing and the damper rod installed in the housing of the actuator to the actuator of the continuous variable damper that the damper rod is easily fixed to the housing To provide.

도 3은 본 발명에 따른 연속가변 댐퍼용 액츄에이터를 도시한 단면도이다. 이에 도시된 바와 같이, 내부가 중공으로 마련된 하우징(1)이 마련되고, 이 하우징(1)의 내부상측에는 다수의 부품과 함께 부싱(5)이 설치된다. 그리고 내부 중심축이 상,하방 관통형성된 부싱(5)의 내부에는 액츄에이터 샤프트(2)가 설치되고, 이 액츄에이터 샤프트(2)의 하측 선단에는 콘트롤로드(4)가 마련된다.3 is a cross-sectional view showing an actuator for a continuously variable damper according to the present invention. As shown in the drawing, a housing 1 having a hollow inside is provided, and a bushing 5 is installed at the upper side of the housing 1 together with a plurality of parts. An actuator shaft 2 is installed inside the bushing 5 through which the inner central axis is penetrated up and down, and a control rod 4 is provided at the lower end of the actuator shaft 2.

이 콘트롤로드(4)의 상측 선단은 액츄에이터 샤프트(20의 하측 선단 내부로 삽입되는 것으로서, 그 외측으로는 댐퍼로드(3)가 구비되고, 이 댐퍼로드(3)의 하우징(1)의 내부에 삽입되는 측 외주면에는 나사부(30)가 형성된다.The upper end of the control rod 4 is inserted into the lower end of the actuator shaft 20, and the damper rod 3 is provided on the outside thereof, and the damper rod 3 is provided inside the housing 1 of the damper rod 3. The thread portion 30 is formed on the side outer circumferential surface to be inserted.

한편 본 발명에서는 댐퍼로드(3)가 하우징(1)에 용이하게 고정되도록 댐퍼로드(30와 부싱(5)이 체결 가능하게 마련된다.Meanwhile, in the present invention, the damper rod 30 and the bushing 5 are provided to be fastened so that the damper rod 3 is easily fixed to the housing 1.

즉, 댐퍼로드(3)와 마주하는 부싱(5)이 일측에는 나사부(30)가 삽입될 수 있도록 댐퍼로드(3) 측으로 연장되며 내부가 중공으로 마련된 연장부(50)가 마련되는데, 그 내부면에는 나사부(30)와 체결 가능하도록 암나사부(52)가 형성되는 것이다.That is, the bushing 5 facing the damper rod 3 extends to the damper rod 3 side so that the threaded portion 30 can be inserted at one side thereof, and an extension part 50 provided with a hollow is provided. The female threaded portion 52 is formed on the surface to be fastened to the threaded portion 30.

이와 같이 구성된 본 발명의 연속가변댐퍼용 액츄에이터는, 부싱(5)의 하부 주연이 햐항되게 길게 연장되는 연장부(50)를 형성하여 상기 연장부(50)에 댐퍼로드(3)의 끝단을 설치하게 된다. 이때 부싱(5)과 댐퍼로드(3)는 각각에 마련된 턱이 하우징(1)의 지지를 받는 상태에서 체결되므로 각각 하우징(1)에 밀착되어 고정되는 것이다.The continuously variable damper actuator of the present invention configured as described above forms an extension part 50 which extends long so that the lower periphery of the bushing 5 rests, and the end of the damper rod 3 is installed on the extension part 50. Done. At this time, the bushing (5) and the damper rod (3) is fastened in a state in which the jaws provided in each of the support of the housing (1) is in close contact with the housing (1) is fixed.

또, 중공체로 되는 댐퍼로드(3)의 내측으로 끼워진 콘트롤로드(4)는 액츄에이터 샤프트(2)와 중심이 일치하게 되고, 이러한 상태에서 댐퍼로드(3)를 연장부(50)에 설치하면 콘트롤로드(4)는 액츄에이터 샤프트(2)에 쉽게 끼워지며 설치되는 것이다.In addition, the control rod 4 fitted inside the damper rod 3, which becomes a hollow body, is centered with the actuator shaft 2, and in this state, when the damper rod 3 is installed in the extension portion 50, the control rod 4 is controlled. The rod 4 is easily fitted and installed on the actuator shaft 2.

따라서, 종래의 액츄에이터에서와 같이 콘트롤로드(4)와 액츄에이터 샤프트(2)의 중심이 일치하지 않는 문제와 이를 개선한 종래의 또 다른 액츄에이터에서와 같이 좁은 공간에 각각의 부싱과 너트를 설치하는데에 따른 복잡한 공정과 소형의 너트를 별도의 고정부재없이 하우징의 내부에 설치위치를 정하는데에 따른 문제점들을 해소할 수 있게 되는 것이다.Therefore, as in the conventional actuator, the center of the control rod 4 and the actuator shaft 2 do not coincide with each other, and each bushing and nut are installed in a narrow space as in another conventional actuator which has improved the problem. According to the complicated process and the small nut can be solved the problems caused by the installation position of the inside of the housing without a separate fixing member.

이처럼 본 발명에서는 부싱(5)의 구조를 개선하여 상기 부싱(5)에 댐퍼로드(3)를 고정되게 조립하는 것만으로 콘트롤로드(4)가 샤프트(2)에 함께 조립되므로써 댐퍼로드(3)의 설치공정이 간편해진다.As described above, in the present invention, the damper rod 3 is improved by only assembling the damper rod 3 to the bushing 5 by improving the structure of the bushing 5. Installation process is simplified.

이상에서 설명한 바와 같이 본 발명에 따른 연속가변댐퍼용 액츄에이터는, 액츄에이터의 하우징에 댐퍼로드가 고정되게 조립함에 있어 하우징에 직접 댐퍼로드가 고정되게 조립하는 것으로, 하우징의 내부에 부싱을 설치하는 것으로서 그 설치위치가 결정된다.As described above, the actuator for continuous variable dampers according to the present invention is to assemble the damper rod directly fixed to the housing in assembling the damper rod fixed to the housing of the actuator, and to install the bushing inside the housing. The installation location is determined.

즉, 하우징의 내부에 삽입하는 공정 및 그 설치위치의 경정이 부싱의 설치로 인해 동시에 이루어지는 것이다. 또 부싱에 댐퍼로드를 고정되게 조립하는 것만으로 콘트롤로드와 액츄에이터 샤프트의 설치 위치가 일치되므로 댐퍼로드의 설치공정이 간편해지는 이점이 있다.That is, the process of inserting the inside of the housing and the fixation of its installation position are simultaneously performed due to the installation of the bushing. In addition, since the mounting positions of the control rod and the actuator shaft coincide simply by assembling the damper rod fixedly to the bushing, the installation process of the damper rod is simplified.
