본 고안은 자동차의 유체제어식 엔진마운팅에 관한 것으로, 특히 엔진룸내 엔진을 지지하는 엔진마운팅브라켓트이 진동의 정도에 따라 유동량이 제어되는 유체에 의해 지지되어 엔진의 공회전시 발생되어 차체로 전달되는 진동이 저감될 수 있도록 된 자동차의 유체제어식 엔진마운팅에 관한 것이다.The present invention relates to a fluid-controlled engine mounting of an automobile, and in particular, an engine mounting bracket for supporting an engine in an engine room is supported by a fluid whose flow rate is controlled according to the degree of vibration, thereby reducing vibration generated when the engine is idle and transmitted to the vehicle body. It relates to a fluid controlled engine mounting of a vehicle that can be.
일반적으로 자동차의 엔진이 가동중일 때에는 피스톤과 컨넥팅로드의 상하운동에 의한 중심위치의 주기적인 변화와, 실린더의 축방향으로 생기는 왕복운동에 따른 관성력 및, 크랭크축에 가해지는 회전력의 주기적인 변화등의 복합적인 요인으로 인해 엔진에서 소음과 진동이 발생되는 실정이다.In general, when the engine of a vehicle is in operation, the periodic change of the center position by the vertical movement of the piston and the connecting rod, the inertia force due to the reciprocating motion occurring in the axial direction of the cylinder, and the periodic change of the rotation force applied to the crankshaft Due to the complex factors such as noise and vibration is generated in the engine.
이와 같이 엔진에서 발생된 소음이나 진동을 차체에 전달되지 않도록 하기 위해서 종래에는 제2도에 도시된 바와 같이 엔진(21)의 하부에 부착된 엔진마운팅브라켓트(22)이 차체의 플로워판넬에 지지된 대략 환형의 엔진마운팅(23)에 고정되어, 이 엔진(21)에서 발생되어 엔진마운팅브라켓트(22)으로 전달된 진동이 엔진마운팅(23)에서 감쇄되어 차체에 전달되지 않도록 되어 있었다.In order to prevent the noise or vibration generated by the engine from being transmitted to the vehicle body, the engine mounting bracket 22 attached to the lower part of the engine 21 is conventionally supported on the floor panel of the vehicle body as shown in FIG. The vibrations generated by the engine 21 and transmitted to the engine mounting bracket 22 are attenuated by the engine mounting 23 and are not attenuated by the engine mounting 23 so as not to be transmitted to the vehicle body.
그러나 상기와 같은 환형의 엔진마운팅(23)은 비교적 비용이 적게 들면서 주로 동력전달기구의 롤(Roll)진동을 절연시키는 것을 목적으로 하는 것인데, 엔진의 공회전시 발생되는 진동과 엔진의 회전수가 약 3000rpm이상으로 진동이 100Hz이상부터는 진동을 완화시키는 감쇄력이 작기 때문에 진동 및 소음을 저감시키는 대책에 기여할 수 없는 단점이 있었다.However, the annular engine mounting 23 as described above is relatively inexpensive, and mainly aims to insulate the roll vibration of the power transmission mechanism. The vibration generated during idling of the engine and the engine speed are about 3000 rpm. Since the damping force for alleviating the vibration is small from the vibration above 100Hz has had a disadvantage that can not contribute to the measures to reduce the vibration and noise.
이에 본 고안은 상기와 같은 단점을 해결하기 위해 안출된 것으로, 엔진룸내 엔진을 지지하는 엔진마운팅브라켓트이 받는 진동의 정도에 따라 유동량이 제어되는 유체에 의해 지지되어 엔진의 공회전시 발생되어 차체로 전달되는 진동과 소음을 감쇄시킬 수 있도록 된 자동차의 유체제어식 엔진마운팅을 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above disadvantages, and is supported by a fluid whose flow rate is controlled according to the degree of vibration received by an engine mounting bracket for supporting an engine in an engine room, which is generated when the engine is idle and transmitted to a vehicle body. The aim is to provide a fluid controlled engine mounting of a vehicle that is capable of damping vibrations and noise.
상기와 같은 목적을 달성하기 위한 본 고안은, 엔진의 하부에서 일측선단에 고무로 된 가동부재를 갖춘 엔진마운팅브라켓트가 부착되고, 이 가동부재는 내부에 고무를 충진하고 있는 상부부재와 하부부재로 이루어진 엔진마운팅의 상부중앙에 형성된 삽입부에 상/하로 습동가능하게 삽입되며, 이 삽입부내에는 유체서브탱크로부터 관로를 매개로 이송된 유체가 저장되는 한편, 이 관로에는 ECU에 의해 제어를 받는 밸브와 모터가 설치되어 이루어져 있다.The present invention for achieving the above object is attached to the engine mounting bracket having a rubber movable member at one end of the lower end of the engine, the movable member is the upper member and the lower member filled with rubber therein; It is inserted into the insert formed in the upper center of the engine mounting made to be slidable up and down, in which the fluid transferred from the fluid sub-tank via the pipeline is stored, while the valve is controlled by the ECU And motor is installed.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 유체제어식 엔진마운팅의 구성도이다.1 is a block diagram of a fluid controlled engine mounting according to the present invention.
보 고안은 도면에 도시된 바와 같이, 일선단에 고무로 된 가동부재(1)를 갖춘 엔진마운팅브라켓트(2)가 엔진(3)의 하측부에 부착되어 고정되고, 이 엔진마운팅브라켓트(2)의 선단 가동부재(1)는 금속재의 상부부재(4)와 하부부재(5)사이의 내부에 고무(6)로서 충진된 엔진마운팅(7)의 상부중앙에 형성된 삽입부(8)에 상/하로 습동가능하게 삽입되며, 이 삽입부(8)내에는 유체서브탱크(9)로부터 관로(10)를 통해 이성된 유체(11)가 저장되는 한편, 이 관로(10)에는 ECU(12)에 의해 제어를 받는 밸브(13)와 모터(14)가 설치되어 이루어진다.As shown in the figure, an engine mounting bracket 2 having a rubber movable member 1 at one end thereof is attached and fixed to the lower side of the engine 3, and the engine mounting bracket 2 The front end movable member 1 of the upper / lower portion of the upper portion 4 and the lower member 5 of the metal material in the upper portion of the insertion portion 8 formed in the upper center of the engine mounting (7) filled with rubber (6) It is inserted slidably downward, and in the inserting portion 8, the fluid 11 transferred from the fluid sub tank 9 through the conduit 10 is stored, while the conduit 10 is stored in the ECU 12. The valve 13 and the motor 14 which are controlled by this are provided.
여기서 상기 삽입부(8)에는 가동부재(1)의 하부로 가동판(15)이 설치되어 있다.In this case, the insertion plate 8 is provided with a movable plate 15 under the movable member 1.
그리고 상기 엔진마운팅(7)의 하부부재(5)에는 이 엔진마운팅(7)이 차체의 플로워판넬에 고정결합되기 위한 볼트(16)가 구비되어 있다.The lower member 5 of the engine mounting 7 is provided with a bolt 16 for fixing the engine mounting 7 to the follower panel of the vehicle body.
따라서 상기와 같이 엔진(3)을 지지하는 엔진마운팅브라켓트(2)가 상기 ECU(12)에 의해 제어받아 유체서브탱크(9)로부터 토출되는 가변적인 양의 유체(11)를 저장하고 있는 엔진마운팅(7)내의 삽입부(8)에 의해 지지되면, 즉 엔진(3)의 가동에 있어서 진동이 특히 심한 공회전시 발생되는 진동에 의해 엔진마운팅브라켓트(2)가 엔진마운팅(7)의 삽입부(8)내에서 상/하로 떨리면서 움직일 때 ECU(12)에 의해 제어받은 밸브(13)와 모터(14)는 각각 개방되면서 동작되어 유체서브탱크(9)내부에 저장된 유체(11)를 관로(10)를 통해 삽입부(8)내부로 토출시켜 엔진마운팅브라켓트(2)의 진동을 감쇄시켜 주게 되는데, 이때 ECU(12)에 의해 제어받아 유체서브탱크(9)로부터 토출되는 유체(11)의 양은 엔진(3)의 rpm에 부합되어 적절한 수준임은 물론이다.Accordingly, the engine mounting bracket 2 supporting the engine 3 stores the variable amount of fluid 11 discharged from the fluid sub tank 9 under the control of the ECU 12. The engine mounting bracket (2) is supported by the insert (8) in the engine (7), that is, the engine mounting bracket (2) is inserted into the engine (7) by the vibration generated when the engine (3) is particularly vibrating. 8) The valve 13 and the motor 14 controlled by the ECU 12 are operated while being open and shaken up and down to move the fluid 11 stored in the fluid sub tank 9 into the pipeline 10 The vibration of the engine mounting bracket 2 is attenuated by discharging to the inside of the insertion part 8 through), wherein the amount of fluid 11 controlled by the ECU 12 is discharged from the fluid sub tank 9. Of course, it is at an appropriate level in accordance with the rpm of the engine 3.
또한, 상기 삽입부(8)에 설치된 가동판(15)은 엔진(3)의 가동에 따른 엔진마운팅브라켓트(2)의 상/하진동시 가동부재(1)가 삽입부(8)내의 유체(11)를 가압함으로 인해 유체(11)가 관로(10)를 통해 유체서브탱크(9)내로 유입될 때 이 유체(11)내의 에너지를 일부 흡수시켜 주는 역할을 하게 된다.In addition, the movable plate 15 installed in the inserting portion 8 has the movable member 1 at the up / down vibration of the engine mounting bracket 2 according to the operation of the engine 3. By pressurizing), when the fluid 11 is introduced into the fluid sub tank 9 through the conduit 10, the fluid 11 absorbs some energy in the fluid 11.
이상 설명한 바와 같이 본 고안 자동차의 유체제어식 엔진마운팅에 의하면, 엔진(3)을 지지하는 엔진마운팅브라켓트(2)가 ECU(12)에 의해 토출되는 양이 제어받는 유체(11)를 저장하고 있는 엔진마운팅(7)내의 삽입부(8)에 의해 지지되어 엔진(3)의 공회전시 발생되는 진동이 유체서브탱크(9)내부에 저장된 유체(11)에 의해 감쇄됨에 따라, 차체로 전달되는 진동과 소음을 감쇄시킬 수 있는 효과를 가지게 된다.As described above, according to the fluid-controlled engine mounting of the inventive vehicle, an engine in which the engine mounting bracket 2 supporting the engine 3 stores the fluid 11 whose volume is controlled by the ECU 12 is controlled. As the vibration generated when the engine 3 is idling supported by the insert 8 in the mounting 7 is attenuated by the fluid 11 stored in the fluid sub tank 9, It has the effect of reducing the noise.
