Description

능동 감쇠제어 마운트{active damping control mount}Active damping control mount

본 발명은 능동 감쇠제어 마운트에 관한 것으로서, 보다 상세하게는 외부로부터의 전원을 공급 받지 않고 자가 발전하여 작동되는 간단한 구성의 능동 감쇠제어 마운트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active attenuation control mount, and more particularly, to an active attenuation control mount having a simple configuration that is operated by self-generation without being supplied with power from the outside.

도 1에는 종래 기술에 의한 능동 감쇠제어 마운트의 구조가 도시되어 있는바, 고전압발생장치(100)는 배터리(102)로부터 전력을 공급 받아 고전압을 발생시키며, 차체(104)와 마운트하우징(106)의 사이에 설치된 변위센서(108)의 신호를 받은 컨트롤러(110)는 상기 고전압발생장치(100)에서 발생된 고전압을 상기 변위센서(108)의 신호에 따라 마운트 내부의 전극판(112)에 가하도록 되어 있으며, 상기 전극판(112)에서는 가해진 고전압에 의해 전기장을 형성하게 되고, 상기 마운트 내부에 충진된 ER유체(Electro-rheological Fluid; 114)는 상기 전극판(112)에 의해 형성된 전기장을 통과하는 유동저항의 변화로 마운트의 감쇠력이 가변되도록 하고 있다.1 shows a structure of an active attenuation control mount according to the prior art, the high voltage generator 100 receives power from the battery 102 to generate a high voltage, and the vehicle body 104 and the mount housing 106. The controller 110 receiving the signal of the displacement sensor 108 installed in between applies the high voltage generated by the high voltage generator 100 to the electrode plate 112 inside the mount according to the signal of the displacement sensor 108. The electrode plate 112 forms an electric field by the high voltage applied thereto, and the ER fluid (Electro-rheological Fluid) 114 filled in the mount passes through the electric field formed by the electrode plate 112. The damping force of the mount is varied by changing the flow resistance.

상기 ER유체(114)의 기본적인 특성은 전기장이 가해지면 유체 내의 입자들이 클러스터를 형성하며 결합하고, 이로 인해 항복 전단응력이 증가하면서 유동저항이 증가하는 특성이 있는바, 상기 변위센서(108)에서 감지되는 신호에 따라 전극판(112)에 제공되는 고전압이 변화되고, 상기 전극판(112)에 제공되는 전압의 변화에 따라 변화되는 전기장의 세기에 따라 상기 ER유체(114)의 유동저항이 변화됨에 의해 마운트의 전체적인 감쇠력이 가변되도록 한 것이다.The basic characteristic of the ER fluid 114 is that the particles in the fluid are combined to form a cluster when an electric field is applied, thereby increasing the flow resistance as yield shear stress increases, bar displacement in the displacement sensor 108 The high voltage provided to the electrode plate 112 is changed according to the detected signal, and the flow resistance of the ER fluid 114 is changed according to the intensity of the electric field that is changed according to the change of the voltage provided to the electrode plate 112. This allows the overall damping force of the mount to be varied.

그런데, 상기한 바와 같은 능동 감쇠제어 마운트는 상기한 바와 같이 변위센서(108)와 컨트롤러(110) 및 고전압발생장치(100) 등 필요로 하는 부수적이 부품이 많아 비용이 많이 들고 부피가 커져서 차량에 적용하기에 어려움이 있고, 배터리(102)로부터 전원을 공급 받아야 하므로 배터리의 전원의 소모시키는 문제점이 있으며, 장치의 복잡성으로 인해 내구 신뢰성이 저하되는 문제점이 있다.However, the active damping control mount as described above has many additional parts, such as the displacement sensor 108, the controller 110, and the high voltage generator 100, which are expensive and bulky. There is a difficulty in applying, and since the power must be supplied from the battery 102, there is a problem of consuming the power of the battery, there is a problem that the durability reliability is lowered due to the complexity of the device.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 보다 간단한 구성을 가지면서도 외부로부터의 전원공급 없이 능동적으로 그 감쇠력이 제어되도록 함으로써, 차량 탑재성이 용이하고 내구성이 향상되며 원가를 절감시킬 수 있도록 한 능동 감쇠제어 마운트를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, by having a simpler configuration, the damping force is actively controlled without supplying power from the outside, the vehicle is easy to mount, durability is improved and cost is reduced The purpose is to provide an active damping control mount that can be saved.

And permanent magnets;

상기 감지코일과 연결되어 감지코일에서 유도된 유도전류를 증폭하는 트랜스포머와;A transformer connected to the sense coil to amplify the induced current induced in the sense coil;

상기 트랜스포머로부터의 전압을 공급 받도록 마운트 액실의 ER유체 상하 유동로에 설치된 두 전극판을 포함하여 구성된 것을 특징으로 한다.It characterized in that it comprises two electrode plates installed in the vertical flow path of the ER fluid of the mount liquid chamber to receive the voltage from the transformer.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 능동 감쇠제어 마운트의 구성을 도시한 도면이고, 도 3은 그 평면도로서, 마운트는 종래와 같이 차체(1)와 같은 피마운팅물체에 밀착되어 고정되는 마운트하우징(3)과, 엔진과 같은 마운팅물체에 밀착되어 일체로 거동하는 마운트상판(5)의 사이에 러버(7)와 ER유체(9)를 저장하고 있는 액실(11)을 구비하고 있다.Figure 2 is a view showing the configuration of the active damping control mount according to the present invention, Figure 3 is a plan view, the mount is mounted to the mounting housing (3) in close contact with the mounting object, such as the vehicle body 1 as in the prior art And a liquid chamber 11 for storing the rubber 7 and the ER fluid 9 between the mounting top plates 5 which are in close contact with a mounting object such as an engine and behave integrally.

여기에 종래와는 달리 상기 마운트하우징(3)과 마운트상판(5)의 사이에 서로 간격을 두고 감지코일(13) 및 영구자석(15)이 설치되어 있으며, 상기 감지코일(13)과 연결되어 감지코일(13)에서 유도된 유도전류를 증폭하는 트랜스포머(17)와, 상기 트랜스포머(17)로부터의 전압을 공급 받도록 마운트 액실(11)의 ER유체 상하 유동로에 두 전극판(19)이 구비되어 있는 구조이다.Unlike the conventional one, the detection coil 13 and the permanent magnet 15 are installed at intervals between the mount housing 3 and the mount top plate 5, and are connected to the detection coil 13. Two electrode plates 19 are provided in the transformer 17 for amplifying the induced current induced in the sensing coil 13 and in the upper and lower flow paths of the ER fluid of the mount liquid chamber 11 to receive the voltage from the transformer 17. It is a structure.

상기 감지코일(13)은 도시된 바와 같이 상기 마운트상판(5)에 형성된 감지구멍(21)에 동심원을 이루는 원형으로 설치되고, 상기 영구자석(15)은 상기 감지코일(13)이 이루는 원의 중심축을 따라 상대적인 이동을 일으킬 수 있는 막대형으로 설치되어 있으며, 물론 서로의 설치위치를 바꾸는 것도 가능하다.The sensing coil 13 is installed in a circular concentric circle in the sensing hole 21 formed in the top plate 5, as shown, the permanent magnet 15 is formed of a circle formed by the sensing coil 13 It is installed in a rod shape that can cause relative movement along the central axis, and of course, it is also possible to change the installation position of each other.

상기 트랜스포머(17)는 도 4에 도시된 바와 같이 상기 두 전극판(19)의 외측에 설치된 원형철심(23)과, 상기 감지코일(13)과 연결되며 상기 원형철심(23)에 권선된 1차코일(25)과, 상기 1차코일(25)보다 많은 권선수로 상기 원형철심(23)에 권선된 2차코일(27)로 구성되어 인접한 전극판(19)으로 증폭된 전력을 제공할 수 있도록 되어 있다.As shown in FIG. 4, the transformer 17 is connected to the circular iron core 23 provided at the outside of the two electrode plates 19 and the sensing coil 13 and wound around the circular iron core 23. The secondary coil 27 wound around the circular iron core 23 with the number of turns of the primary coil 25 and the primary coil 25 may provide amplified power to the adjacent electrode plate 19. It is supposed to be.

물론, 상기 원형철심(23)의 외측은 플라스틱이나 알루미늄과 같이 자력과 전력이 모두 절연되는 재료(29)를 통해 마운트에 고정되도록 되어 있다.Of course, the outer side of the circular iron core 23 is fixed to the mount through a material 29 in which both magnetic force and electric power are insulated, such as plastic or aluminum.

상기한 바와 같이 구성된 능동 감쇠제어 마운트는 엔진과 같은 마운팅물체가 차체(1)와 같은 피마운팅물체에 대하여 유동하게 되면 상기 마운트상판(5)과 마운트하우징(3) 사이에 상대적인 움직임이 생기게 되고, 상기와 같은 상대적인 움직임은 상기 감지코일(13)과 영구자석(15)의 상대적인 움직임을 발생시키게 된다.The active damping control mount configured as described above has relative movement between the mount top plate 5 and the mount housing 3 when a mounting object such as an engine flows with respect to a mounted object such as a vehicle body 1, Such relative movement will cause relative movement of the sensing coil 13 and the permanent magnet 15.

상기 감지코일(13)에는 상기 영구자석(15)과의 상대적인 움직임에 의해 유도전류가 발생되고, 상기 유도전류는 상기 트랜스포머(17)의 1차코일(25)로 전달된다.Induced current is generated in the sensing coil 13 by relative movement with the permanent magnet 15, and the induced current is transmitted to the primary coil 25 of the transformer 17.

상기 1차코일(25)에 공급된 유도전류는 상기 2차코일(27)과의 권선수에 비례하는 고전압으로 증폭되는바, 상기와 같이 2차코일(27)에 의해 발생된 고전압은 상기 전극판(19)에 제공된다.The induced current supplied to the primary coil 25 is amplified by a high voltage proportional to the number of turns with the secondary coil 27. As described above, the high voltage generated by the secondary coil 27 is the electrode. It is provided on the plate 19.

상기 전극판(19)은 제공 받은 전압에 의해 전기장을 형성하고, 상기 액실(11) 내에 충전되어 있는 ER유체(9)는 상기 두 전극판(19) 사이에 형성된 전기장이 형성하는 유로를 통과할 때 발생시키는 유동저항에 의해 마운트의 감쇠력을 변화시키게 된다.The electrode plate 19 forms an electric field by the provided voltage, and the ER fluid 9 filled in the liquid chamber 11 passes through a flow path formed by the electric field formed between the two electrode plates 19. The damping force of the mount is changed by the flow resistance generated at the time.

물론, 상기 마운트하우징(3)과 마운트상판(5) 사이의 상대적인 움직임이 크면 클수록 상기 감지코일(13)에서의 유도전류는 커지고, 그에 따라 상기 트랜스포머(17)에서 형성되는 전압도 커져서 상기 전극판(19)들이 형성하는 전기장의 세기도 커지며, 이는 곧 ER유체(9)의 유동저항이 커지는 것을 의미한다.Of course, as the relative movement between the mount housing 3 and the mount top plate 5 increases, the induced current in the sensing coil 13 increases, and accordingly, the voltage formed in the transformer 17 also increases. The intensity of the electric field formed by the (19) also increases, which means that the flow resistance of the ER fluid (9) increases.

따라서, 상기와 같은 구조의 마운트는 차체(1)와 같은 피마운팅물체에 대한 엔진과 같은 마운팅물체의 상대적인 움직임의 정도에 따라서 능동적으로 그 감쇠력이 자동적으로 변화하게 되는 것이다.Therefore, the mount of the structure as described above actively changes its damping force automatically according to the degree of relative movement of the mounting object such as the engine with respect to the mounted object such as the vehicle body (1).

이상과 같이 본 발명에 의하면, 보다 간단하고 컴팩트한 구성을 가지면서도 외부로부터의 전원공급 없이 능동적으로 그 감쇠력이 제어되도록 함으로써, 차량 탑재성이 용이하고 내구성이 향상되며 원가를 절감시킬 수 있도록 한다.As described above, according to the present invention, the damping force is actively controlled without supplying power from the outside while having a simpler and more compact configuration, thereby making it easy to mount the vehicle, improving durability and reducing costs.
