일반적으로 차량용 엔진 마운트는 차체에 고정되어 엔진을 지지하는 부품으로 엔진의 진동이 차체측으로 전달되는 것을 방지하는 방진기능을 하며, 그 종류로는 통고무로 이루어진 러버 엔진 마운트와, 고무내에 액체를 봉입하여 진동의 감쇠력을 크게 한 액체봉입 엔진 마운트 등이 있다.In general, an engine mount for a vehicle is a component that is fixed to a vehicle body to support the engine, and has a dustproof function to prevent the vibration of the engine from being transmitted to the vehicle body. The type includes a rubber engine mount made of solid rubber and a liquid in rubber. Such as liquid-sealed engine mounts that increase vibration damping force.

상기한 액체봉입 엔진 마운트가 도 3에 도시되어 있다.The above liquid enclosed engine mount is shown in FIG. 3.

상기한 액체봉입 엔진 마운트가 방진 작용을 하는 방진고무(102)와, 이 방진고무(102)의 일측으로 간막이 판(104)에 의해 이격된 제1 챔버(106) 및 제2 챔버(108)를 포함한다.The above-mentioned liquid-sealed engine mount has a dustproof rubber 102 having a dust-proof action, and a first chamber 106 and a second chamber 108 spaced apart by a partition plate 104 on one side of the dustproof rubber 102. Include.

상기한 간막이 판(104)의 일측에 오리피스관(110)이 설치되어 상기 제1 챔버(106)와 제2 챔버(108) 사이를 서로 연결시키는 유로를 형성하고, 제 2챔버(108)의 하단으로 다이어프램 스프링(112)이 위치한다.An orifice tube 110 is installed at one side of the partition plate 104 to form a flow path connecting the first chamber 106 and the second chamber 108 to each other, and the lower end of the second chamber 108. The diaphragm spring 112 is located.

상기한 오리피스관은 상측으로 제1 챔버(106)와 연결되어 유체가 유입 또는 배출되는 유로(114)가 형성되고, 하측으로 제2챔버(108)와 연결되어 유체가 배출되는 유로(116)가 형성되어 있다.The orifice tube is connected to the first chamber 106 upwards to form a flow path 114 through which fluid is introduced or discharged, and a flow path 116 connected to the second chamber 108 downward to discharge the fluid.

이러한 방진부재(2)의 하측에 일정 밀도를 갖는 유체가 채움되는 제1 챔버(4)가 형성되며, 이 제1쳄버(4)의 하측으로 역시 일정 밀도를 갖는 유체가 채움되는 제2 쳄버(6)가 위치한다.A first chamber 4 in which a fluid having a certain density is filled is formed below the dustproof member 2, and a second chamber in which fluid having a certain density is also filled in the lower side of the first chamber 4 ( 6) is located.

상기한 제1 챔버(4)와 제2 쳄버(6) 사이에는 제1 챔버(4)의 유체가 제 2챔버(6)측으로 유입되거나 또는 제2 챔버(6)측의 유체가 제1 챔버(4)측으로 배출되는 오리피스관(8)이 장착된다.Between the first chamber 4 and the second chamber 6, the fluid in the first chamber 4 flows into the second chamber 6 side, or the fluid in the second chamber 6 side flows in the first chamber ( 4) The orifice tube 8 discharged to the side is mounted.

상기한 오리피스관(8)은 도우넛 형상의 부재로서, 원주방향을 형성된 공간의 상측으로 상기 제1 챔버(4)와 연통되는 제1유로(12)가 형성되고, 하측으로 제2 챔버(6)와 연통되는 제2 유로(14)가 형성된다.The orifice tube 8 is a donut-shaped member, in which a first flow passage 12 communicating with the first chamber 4 is formed above the space in which the circumferential direction is formed, and the second chamber 6 is downward. The second flow path 14 in communication with the second is formed.

이러한 오리피스관(8)의 일측으로 오리피스관 유로를 가변시킬 수 있는 감쇠력 가변수단이 위치한다.One side of the orifice tube (8) is a damping force variable means for varying the orifice tube flow path is located.

상기한 감쇠력 가변수단은 상기 오리피스관(8)의 일측에 위치하여 상하로 이동하면서 상기 오리피스관(8)의 유로를 가변시킬 수 있도록 개폐작용을 하는 개폐수단과, 이 개폐수단을 차량의 운행 조건에 따라 제어하는 제어수단을 포함한다.The damping force variable means is located on one side of the orifice tube (8), the opening and closing means for opening and closing to change the flow path of the orifice tube (8) while moving up and down, and the opening and closing means is a vehicle driving condition Control means for controlling in accordance with.

상기한 개폐수단은 상기 오리피스관(8)의 상단측에 밀봉 가능하게 얹혀지는 평판상의 간막이부재(16)와, 이 간막이부재(16)의 수직방향 하측으로 원통상의 개폐부재(18)가 일체로 연장 형성된다.The opening and closing means includes a flat partition member 16 mounted on the upper end side of the orifice tube 8 and a cylindrical opening and closing member 18 integrally downward in the vertical direction of the partition member 16. Is formed extending.

상기한 간막이부재(16)는 상측면이 상기 제어수단과 연결되고, 하측면이 상기 오리피스관(8)의 상단측과 밀착되어 상기 오리피스관(8)의 제1유로의 크기를 가변시키는 역할을 한다.The partition member 16 has an upper side connected to the control means, and the lower side is in close contact with the upper end of the orifice tube 8 to change the size of the first flow path of the orifice tube 8. do.

즉 상기 제어수단에 의해 간막이 부재(16)가 상측으로 이동하면 제1유로(12)는 완전히 개방되어 유체의 이동량을 많게 하고, 간막이부재(16)와 제어수단과의 사이에 개재된 탄성부재(20)에 의해 간막이부재(16)가 오리피스관(8)의 상측면이 밀착되면 제1 유로(12)가 반쯤 닫히게 되어 유체의 이동량을 줄인다.That is, when the partition member 16 is moved upward by the control means, the first passage 12 is completely opened to increase the amount of fluid movement, and the elastic member interposed between the partition member 16 and the control means ( 20, when the partition member 16 is in close contact with the upper surface of the orifice tube 8, the first flow path 12 is half-closed to reduce the amount of fluid movement.

상기한 개폐밸브(18)는 오리피스관(8)의 내주연에 밀착되어 상하로 이동하면서 이 오리피스관(8)의 내주연에 일정범위로 형성된 제3 유로(22)의 개폐작용을 한다.The on-off valve 18 is in close contact with the inner circumference of the orifice tube 8 and moves up and down to open and close the third flow passage 22 formed in a predetermined range on the inner circumference of the orifice tube 8.

상기한 오리피스관(8)의 하단 원주방향으로 다이어프램 스프링(24)이 장착되고, 이 다이어프램 스프링(24)과 하우징(26)과의 사이에 공기실(28)이 형성되며, 이 공기실(28) 일측이 외기가 유입되는 통로(30)가 형성된다.The diaphragm spring 24 is mounted in the lower circumferential direction of the orifice tube 8, and the air chamber 28 is formed between the diaphragm spring 24 and the housing 26, and this air chamber 28 ) One side is formed with a passage 30 through which the outside air is introduced.

또한 상기 하우징(26)의 일측에 차체측 또는 엔진측에 장착되는 고정볼트(32)가 결합된다.In addition, a fixing bolt 32 is mounted to one side of the housing 26 to the vehicle body side or the engine side.

상기 다이어프램 스프링(26)은 제2 챔버(6)측으로 유입된 유체가 일정압 이하로 저하되면 제2 챔버(6)측의 유체에 일정압을 부여하여 제1 챔버(4)측으로 돌려보내는 리턴스프링 역할을 한다.The diaphragm spring 26 returns a return spring which gives a constant pressure to the fluid on the second chamber 6 side and returns it to the first chamber 4 side when the fluid flowing into the second chamber 6 side drops below a predetermined pressure. Play a role.

도 2는 상기한 개폐수단을 제어하는 제어수단의 회로도로서, 차량의 아이들상태를 검출하여 그 신호를 전자제어유닛(ECU)(36)에 전달하는 아이들센서(34)와, 상기 전자제어유닛(36)에 의해 작동되어 상기 개폐수단을 작동시키는 솔레노이드(38)를 포함한다.2 is a circuit diagram of the control means for controlling the opening and closing means, an idle sensor 34 for detecting an idle state of a vehicle and transmitting a signal to the electronic control unit (ECU) 36, and the electronic control unit ( And a solenoid 38 operated by 36 to operate the opening and closing means.

이와 같이 이루어진 본 고안의 차량용 엔진 마운트의 작동상태를 살펴보면, 차량 아이들시 아이들센서(34)는 그 신호를 검출하여 전자제어유닛(ECU)(36)에 보내고, 이 전자제어유닛(ECU)(36)은 그 신호에 의해 솔레노이드(38)를 온시켜, 이 솔레노이드(36)의 작동에 의해 개폐수단을 도면에서 보아 상방향으로 이동시킨다.Looking at the operating state of the vehicle engine mount according to the present invention, the idle sensor 34 detects the signal and sends the signal to the electronic control unit (ECU) 36, and the electronic control unit (ECU) 36. The solenoid 38 is turned on by the signal, and the opening and closing means is moved upward by the operation of the solenoid 36 in the drawing.

상기 개폐수단이 상방향으로 이동시키면 제1유로(12)의 크기가 커지고, 제3유로(22)가 개방되어 제1챔버(4)의 유체가 제1유로(12)를 통해 오리피스관(8)으로 유입되어 제2유로(14)는 물론 제3 유로(22)를 통하여 동시에 제2챔버(6)측으로 유입된다.When the opening and closing means moves upward, the size of the first flow passage 12 increases, and the third flow passage 22 opens so that the fluid in the first chamber 4 flows through the first flow passage 12. ) Flows into the second chamber (6) at the same time through the second flow path (14) as well as through the third flow path (22).

그러므로 유체량의 이동시 유동저항이 적어 감쇠력은 적어진다.Therefore, there is less flow resistance when the fluid volume moves, so the damping force is less.

이와 반대로 차량 주행시에는 솔레노이드(38)가 오프되어, 탄성부재(20)의 탄성력에 의해 개폐수단이 오리피스관(8)에 밀착되어 제1유로(12)의 크기를 작게 하고, 제3유로(22)를 폐쇄하게 된다.On the contrary, when the vehicle runs, the solenoid 38 is turned off, and the opening and closing means is brought into close contact with the orifice tube 8 by the elastic force of the elastic member 20 so that the size of the first passage 12 is reduced, and the third passage 22 ) Will be closed.

그러면 제1챔버(4)측의 유체가 제1유로(12)를 통하여 오리피스관(8)으로 유입되어 제2유로(14)를 통하여 제2챔버(6)측으로 배출된다.Then, the fluid at the side of the first chamber 4 flows into the orifice tube 8 through the first flow passage 12 and is discharged to the second chamber 6 side through the second flow passage 14.

즉 유체가 통과하는 유로의 크기가 작아지므로 유동저항이 커져 감쇠력은 증가된다.That is, since the size of the passage through which the fluid passes is small, the flow resistance is increased and the damping force is increased.

상기한 바와 같이 이루어진 본 고안에 의한 차량용 엔진 마운트는 엔진의 상황변화에 따라 감쇠력을 가변시켜 엔진의 진동이 차체측으로 전달되는 것을 최소화함으로써, 승차감을 향상시킬 수 있다.The vehicle engine mount according to the present invention made as described above may improve the riding comfort by minimizing the transmission of vibration of the engine to the vehicle body by varying the damping force according to the change of the engine condition.
