도 1은 본 발명에 따른 반능동형 스테빌라이져의 구성을 도시한 도면.1 is a view showing the configuration of a semi-active stabilizer according to the present invention.

도 2는 도 1에 도시된 MR 댐퍼의 상세 구성을 도시한 단면도.FIG. 2 is a sectional view showing a detailed configuration of the MR damper shown in FIG. 1. FIG.

본 발명은 반능동형 스테빌라이져에 관한 것이다.The present invention relates to a semi-active stabilizer.

일반적으로 자동차의 현가장치에 구비되는 스테빌라이져는 차체의 횡방향으로 배치되도록 장착되어, 주행중 좌/우측 현가장치의 상대적인 거동자세의 변화에 따라 발생되는 차체의 롤링을 자체적으로 갖고 있는 롤 강성을 매개로 완화시킴으로써, 차체의 거동자세를 보다 더 안정화시키도록 하는 것이다.In general, the stabilizer provided in the suspension of the vehicle is mounted so as to be arranged in the transverse direction of the vehicle, through the roll stiffness that itself has the rolling of the vehicle generated by the change in the relative attitude of the left and right suspension while driving By mitigating, the body posture is further stabilized.

그런데, 종래 통상적인 구조의 스테빌라이져는 봉형상의 단일의 부재로서 차체에 횡방향으로 배치되고, 양측의 선단 부위는 각각 차체측 현가아암에 고정되는 구조로 이루어진다.By the way, the stabilizer of the conventional structure is a rod-shaped single member, arrange | positioned laterally to a vehicle body, and the front end part of both sides is comprised by the structure fixed to the vehicle body side suspension arm, respectively.

따라서, 주행중 차체의 롤 발생시 봉형상의 부재가 가지는 자체 롤 강성에 전적으로 의존하여 차체의 거동자세를 안정화시킬 수 밖에 없으므로, 선회시 주행의 안정성을 최적으로 확보하는 데 그 한계가 있었다.Therefore, since the rolling attitude of the vehicle body can only be stabilized depending on the roll rigidity of the rod-shaped member when the roll of the vehicle body is generated during driving, there is a limit to ensuring the stability of the driving at the time of turning.

이에 본 발명은 상기와 같은 제반 사안들을 해소하기 위해 안출된 것으로, 좌/우측 현가아암 사이에 설치되는 롤바아를 분할하며 이들 사이에 자기유변유체를 이용한 MR 댐퍼를 장착하고, 롤 발생시 롤의 정도에 상응하는 작동전류를 MR 댐퍼에 제공하여 MR 댐퍼로부터 구현되는 감쇠특성의 정도를 가변화시킴으로써, 차체의 거동자세를 최적의 상태로 안정화시킬 수 있도록 하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, and divided the roll bar installed between the left and right suspension arms, and equipped with an MR damper using a magnetorheological fluid therebetween, The purpose of the present invention is to provide an operating current corresponding to the MR damper so as to vary the degree of attenuation characteristic realized from the MR damper, thereby to stabilize the behavior of the vehicle body in an optimal state.

상기 MR 댐퍼와, 상기 MR 댐퍼에 지지된 상기 롤바아 사이를 각각 연결하는 좌/우측 한 쌍의 토션 스프링 및; A pair of left and right torsion springs respectively connecting the MR damper and the roll bar supported by the MR damper;

차량의 주행상태에 따라 상기 MR 댐퍼로부터 구현되어야 하는 최적의 감쇠력을 산출하고, 산출된 감쇠력이 상기 MR 댐퍼로부터 발생될 수 있도록 상기 코일에 적정의 작동전류를 인가하는 제어부를 포함하는 것을 특징으로 한다.And a controller configured to calculate an optimal damping force to be implemented from the MR damper according to the driving state of the vehicle, and apply an appropriate operating current to the coil so that the calculated damping force can be generated from the MR damper. .

도면에 도시된 바와 같이, MR 댐퍼(1)는 내부에 코일(50)과 자기유변유체(magnetorheological fluid; 52)를 구비하고서 차체에 고정된다.As shown in the figure, the MR damper 1 is fixed to the vehicle body with a coil 50 and a magnetorheological fluid 52 therein.

롤바아(3)는 좌/우로 한 쌍으로 분할되고, 상기 MR 댐퍼(1)의 내부에서 분할된 일단이 각각 회전가능하게 지지되며, 타단이 좌/우측 현가아암에 각각 고정된다.The roll bar 3 is divided into left and right pairs, one end divided inside the MR damper 1 is rotatably supported, and the other end is fixed to the left and right suspension arms, respectively.

상기 MR 댐퍼(1)와, 상기 MR 댐퍼(1)에 지지된 상기 롤바아(3) 사이에는 좌/우측 한 쌍의 토션 스프링(5)이 설치되어 있는 바, 보다 상세하게는 상기 토션 스프링(5)의 양단부가 상기 MR 댐퍼(1)의 외측과 상기 롤바아(3)의 선단부 사이에 각각 결합되어 이들 사이를 연결한다.A pair of left and right torsion springs 5 is provided between the MR damper 1 and the roll bar 3 supported by the MR damper 1, and more specifically, the torsion spring ( Both ends of 5) are coupled between the outer side of the MR damper 1 and the front end of the roll bar 3, respectively, to connect them.

상기 MR 댐퍼(1)에 구비된 자기유변유체(52)는 제어부(7)로부터 제어되어 인가되는 작동전류에 의해 그 감쇠특성이 가변적으로 조절되는 바, 이 경우, 상기 제어부(7)는 차량의 주행정보 입력부(11)를 통해 각종 주행상태에 대한 정보(차속과 롤각 등)와 차체의 거동자세 변화에 대한 정보를 검출받은 다음, 검출된 정보로부터 롤거동의 안정성을 부여하는 데 적합한 감쇠력을 산출하고, 산출된 감쇠력이 상기 MR 댐퍼(1)로부터 발생될 수 있도록 상기 코일(50)에 적정의 작동전류를 인가하게 된다.The magnetorheological fluid 52 provided in the MR damper 1 is controlled by the control unit 7 and its attenuation characteristic is variably adjusted by the applied current. In this case, the control unit 7 is a The driving information input unit 11 receives information on various driving conditions (such as vehicle speed and roll angle) and information on changes in the attitude of the vehicle body, and then calculates a damping force suitable for providing stability of the roll behavior from the detected information. In addition, an appropriate operating current is applied to the coil 50 so that the calculated damping force can be generated from the MR damper 1.

이 경우, 상기 제어부(7)는 전원 공급부(9)를 매개로 상기 코일(50)에 인가되는 작동전류의 크기를 조절하도록 구성된다.In this case, the control unit 7 is configured to adjust the magnitude of the operating current applied to the coil 50 via the power supply unit 9.

상기 MR 댐퍼(1)는 상기 코일(50)과 상기 자기유변유체(52) 및 상기 롤바아 (3)의 일단부를 내부에 수용하도록 다수로 분할되어 볼트(B)에 의해 나사결합되는 하우징(54)으로 이루어진다.The MR damper 1 is divided into a plurality of housings 54 and one end portion of the magnetorheological fluid 52 and the roll bar 3 are screwed by a bolt B so as to accommodate therein. )

이 경우, 상기 하우징(54)은 내부에 상기 코일(50)과 상기 자기유변유체(52) 및 상기 롤바아(3)의 일단부를 수용하기 위한 적정의 공간부를 형성함은 물론이다.In this case, the housing 54 forms a proper space portion for accommodating one end of the coil 50, the magnetorheological fluid 52, and the roll bar 3.

상기 하우징(54)은 이의 외주에 마운팅 브라켓(56)이 설치되고, 상기 마운팅 브라켓(56)이 차체의 하부에 고정됨으로써, 상기 MR 댐퍼(1)는 차체에 고정지지될 수 있게 된다.The housing 54 is provided with a mounting bracket 56 on the outer circumference thereof, and the mounting bracket 56 is fixed to the lower portion of the vehicle body, so that the MR damper 1 can be fixed to the vehicle body.

상기 하우징(54)은 상기 좌/우측 한 쌍의 롤바아(3)의 일단부를 각각 회전가능하게 지지하는 한 쌍의 베어링(58)을 구비하고 있어, 상기 롤바아(3)의 일단부는 상기 MR 댐퍼(1)의 내부에서 자유로운 회전이 가능하게 된다.The housing 54 has a pair of bearings 58 rotatably supporting one end of each of the left and right pairs of roll bars 3, and one end of the roll bar 3 has the MR Free rotation inside the damper 1 is enabled.

상기 베어링(58)은 상기 하우징(54)의 양측부에서 볼트(B)에 의해 나사결합되는 보조 마운팅 브라켓(60)을 매개로 고정지지된다.The bearing 58 is fixedly supported via an auxiliary mounting bracket 60 which is screwed by bolts B at both sides of the housing 54.

상기 하우징(54)은 내부에 저장된 상기 자기유변유체(52)의 누설을 방지하기 위해 상기 좌/우측 한 쌍의 롤바아(3)의 외주에 각각 설치된 한 쌍의 리테이너(62)를 구비한다.The housing 54 has a pair of retainers 62 respectively installed on the outer circumference of the left / right pair of roll bars 3 to prevent leakage of the magnetorheological fluid 52 stored therein.

상기 좌/우측 한 쌍의 롤바아(3)는 상호 대향되는 부위에 단면적을 확장시키는 플랜지부(3a)를 일체로 형성하는 바, 이는 상기 코일(50)의 자화시 상기 자기유변유체(52)가 빙햄유체의 거동을 함으로써 부여받게 되는 전단응력을 보다 확장된 부위에 걸쳐 전달받아 상기 롤바아(3)의 회전방향과 반대방향으로 보다 큰 저항 모멘트를 발생시킴으로써, 차체의 거동자세를 보다 효과적으로 안정화시키기 위함인 것이다.The pair of left and right roll bars 3 integrally form a flange portion 3a that extends a cross-sectional area at opposite portions of the roll bar 3, which is the magnetorheological fluid 52 when the coil 50 is magnetized. The shear stress given by the acting of the bingham fluid is transmitted over an extended portion to generate a larger resistance moment in the direction opposite to the rotational direction of the roll bar 3, thereby more effectively stabilizing the behavior of the vehicle body. It is to make it.

이 경우, 상기 자기유변유체(52)는 상기 하우징(54)내에서 상기 플랜지부(3a)의 전 둘레에 걸쳐 고르게 충전됨은 물론이다.In this case, the magnetorheological fluid 52 is, of course, evenly charged over the entire circumference of the flange portion 3a in the housing 54.

따라서, 저속 주행시나 주행중 차체의 롤 발생 정도가 미약하면, 상기 MR 댐퍼(1)의 하우징(54)과 상기 롤바아(3) 사이를 연결하는 상기 토션 스프링(5)이 구현하는 비틀림 복원력만을 이용하여 차체의 거동자세를 안정화시켜 승차감의 저하를 방지한다.Therefore, when the roll generation degree of the vehicle body during low speed driving or driving is weak, only the torsion restoring force implemented by the torsion spring 5 connecting between the housing 54 of the MR damper 1 and the roll bar 3 is used. By stabilizing the behavior posture of the car body to prevent the deterioration of ride comfort.

그리고, 중,고속의 주행시나 주행중 차체의 롤 발생의 정도가 커지게 되면, 상기 토션 스프링(5)이 구현하는 비틀림 복원력에 상기 MR 댐퍼(1)가 구현할 수 있는 감쇠력까지 합산시켜 차체의 거동자세를 안정화시킴으로써 차량의 조종안정성을 향상시킬 수 있게 된다.And, when the degree of roll generation of the vehicle body increases during medium and high speed driving or while driving, the torsion restoring force implemented by the torsion spring 5 is added up to the damping force that the MR damper 1 can implement to move the vehicle body. By stabilizing the control stability of the vehicle can be improved.

이때, 상기 MR 댐퍼(1)가 구현하는 감쇠력은 상기 제어부(7)로부터 전원 공급부(9)를 통해 상기 코일(50)에 인가되는 작동전류의 크기에 의해 결정되는 데, 상기 코일(50)은 작동전류의 인가시 도 2에 화살표로 예시한 바와 같이 주변에 자기장을 형성하게 되고, 이 자기장에 의해 상기 자기유변유체(52)가 빙햄유체의 거동을 하여 상기 롤바아(3)의 플랜지부(3a)에서는 입력되는 운동방향과 반대의 방향으로 전단응력이 발생되어 상기 롤바아(3)의 회전을 억제하려는 방향의 모멘트가 생성되므로, 롤의 정도가 감쇠되고 차체의 거동자세는 안정화될 수 있게 된다.At this time, the damping force implemented by the MR damper 1 is determined by the magnitude of the operating current applied to the coil 50 from the control unit 7 through the power supply unit 9, the coil 50 is When an operating current is applied, as shown by the arrow in FIG. 2, a magnetic field is formed around the magnetic field, and the magnetic rheological fluid 52 behaves as a Bingham fluid, so that the flange portion of the roll bar 3 ( In 3a), the shear stress is generated in a direction opposite to the input direction of motion, thereby generating a moment in a direction to suppress rotation of the roll bar 3, so that the degree of roll is attenuated and the behavior of the vehicle body can be stabilized. do.

이상 설명한 바와 같이 본 발명에 따른 반능동형 스테빌라이져에 의하면, 좌/우측 현가아암 사이에 설치되는 롤바아를 분할하며 이들 사이에 자기유변유체를 이용한 감쇠력을 발생시키는 MR 댐퍼를 장착하고, 롤 발생시 롤의 정도에 상응하는 작동전류를 MR 댐퍼에 제공함으로써, MR 댐퍼로부터 구현되는 감쇠특성의 정도를 가변화시켜 차체의 거동자세를 최적의 상태로 안정화시킬 수 있게 된다.As described above, according to the semi-active stabilizer according to the present invention, an MR damper for dividing the roll bar installed between the left and right suspension arms and generating a damping force using a magnetorheological fluid therebetween, By providing an operating current corresponding to the degree to the MR damper, it is possible to stabilize the behavior posture of the vehicle body by varying the degree of attenuation characteristic realized from the MR damper.
