본 발명은 자동차용 쇽업소버의 자세제어장치에 관한 것으로서, 더욱 상세하게는 단순히 러버만으로 구성된 부시로 이루어진 종래의 차체와 쇽업소버를 연결하는 연결구조에 내측 파이프의 변위 이동이 가능한 가변유체 챔버를 갖는 부시를 장착시킨 자동차용 쇽업소버의 자세제어장치에 관한 것이다. The present invention relates to a posture control device for a shock absorber for an automobile, and more particularly, having a variable fluid chamber capable of displacement movement of an inner pipe in a connection structure connecting a conventional vehicle body and a shock absorber composed of a bush made of only a rubber. It relates to an attitude control device for automobile shock absorbers equipped with a bush.

일반적으로, 자동차의 현가장치는 차축과 연결하여, 차량의 주행 중에 노면으로부터 받는 진동이나 충격을 자동차 차체에 직접적으로 전달되지 않도록 제어하여 차체, 승객, 화물, 등에 손상을 주지 않도록 하고 차량의 승차감을 좋게 만드는 장치이다. In general, the suspension of the vehicle is connected to the axle, so that the vibration or shock received from the road surface is not directly transmitted to the vehicle body while driving the vehicle so as not to damage the vehicle body, passengers, cargo, etc., and the ride comfort of the vehicle. It is a device that makes good.

상기 현가장치는 노면으로부터 충격을 완화시키는 섀시 스프링, 섀시 스프링의 자유진동을 제어하여 승차감을 좋게 하는 쇽업소버, 차량의 롤링(rolling)을 방지하는 스태빌라이저 바 등으로 구성된다. The suspension device is composed of a chassis spring for mitigating the impact from the road surface, a shock absorber for controlling the free vibration of the chassis spring to improve the ride comfort, a stabilizer bar for preventing rolling of the vehicle.

이 중에서 쇽업소버는 자동차의 주행중 스프링이 받는 충격에 의해 발생하는 고유진동을 흡수하여 진동을 빨리 감쇠시켜 승차감을 좋게 하기 위하여 차체와 휠 사이에 장착되어 있다.Among them, the shock absorber is installed between the vehicle body and the wheels to absorb natural vibrations generated by the shocks of the springs while the vehicle is running, to attenuate vibrations quickly, and to improve ride comfort.

본 발명에 따른 자동차용 쇽업소버의 자세제어장치에 있어서, 도 1에 도시된 바와 같이, 마운팅 부시(10)는, 도 1 및 도 2에 도시된 바와 같이, 내측 파이프(11) 및 외측 케이스(12)와, 상기 내측 파이프(11) 및 외측 케이스(12)를 일체 결속시켜 주며 차량의 진동 및 충격을 흡수하는 고무체(13)로 이루어져 있다. In the attitude control apparatus of the shock absorber for automobiles according to the present invention, as shown in Figure 1, the mounting bush 10, as shown in Figures 1 and 2, the inner pipe 11 and the outer case ( 12) and a rubber body 13 which integrally couples the inner pipe 11 and the outer case 12 and absorbs vibration and shock of the vehicle.

이때, 이와 같은 구성으로 이루어진 본 발명에 따른 마운팅 부시(10)는 내측 파이프(11)의 변위 이동이 가능한 가변유체 챔버(chamber)(20)를 구비한 바, 상기 가변유체 챔버(20)는 상기 고무체(13)의 상,하측에 각각 분리된 채로 동심원 상으로 상,하부측 챔버부(21,22)가 형성되어 있으며, 상,하부측 챔버부(21,22)에는 유체가 유입 및 배출될 수 있는 유체 주입구(21a,22a)가 형성되어 있다.At this time, the mounting bush 10 according to the present invention having such a configuration is provided with a variable fluid chamber (chamber) 20 capable of displacement movement of the inner pipe 11, the variable fluid chamber 20 is The upper and lower chamber portions 21 and 22 are formed concentrically on the upper and lower sides of the rubber body 13, and fluid is introduced into and discharged from the upper and lower chamber portions 21 and 22, respectively. Fluid inlets 21a and 22a may be formed.

즉, 상기 마운팅 부시(10)의 상,하단부에 형성된 상,하부측 챔버부(21,22)는 후술하는 스티어링 기어박스의 유압회로(120)와 연결되어 있으며, ECU(100)의 제어를 통해 유압회로(120) 내의 오일이 주입되도록 유체 주입구(21a,22a)가 형성되어 있다.That is, the upper and lower chamber portions 21 and 22 formed at the upper and lower ends of the mounting bush 10 are connected to the hydraulic circuit 120 of the steering gear box to be described later, and are controlled by the ECU 100. Fluid injection ports 21a and 22a are formed to inject oil into the hydraulic circuit 120.

특히, 자동차의 선회시 쇽업소버의 코일 스프링이 압축되는 자동차 외측에 위치한 마운팅 부시(10)의 가변유체 챔버(20)는 자동차의 선회시에 발생하는 롤링량을 최대한 억제하기 위하여 압축 동작과 반대로 작용하는 신장력을 확보할 수 있도록 상기 하부측 챔버부(22)의 유체 주입구(22a)로는 유체인 오일이 주입되고, 반 면에 상부측 챔버부(21)의 유체 주입구(21a)로는 오일이 배출되도록 되어 있다.In particular, the variable fluid chamber 20 of the mounting bush 10 located on the outside of the vehicle in which the coil spring of the shock absorber is compressed during turning of the vehicle acts as opposed to the compression operation in order to minimize the amount of rolling generated during the turning of the vehicle. The fluid is injected into the fluid inlet 22a of the lower chamber 22 to secure the stretching force, and the oil is discharged into the fluid inlet 21a of the upper chamber 21 on the opposite side. It is.

이는 도 3에 도시된 바와 같이, 오일이 주입되는 하부측 챔버부(22)는 팽팽하게 차올라 내측 파이프(11)의 변위 이동이 상측으로 작용하도록 하여 상부측 챔버부(21)에 주입된 오일이 외측 케이스(12)의 한정된 공간 내에서 내측 파이프(11)의 척력에 의해 유체 주입구(21a)를 통해 배출되는 것이다. As shown in FIG. 3, the lower chamber portion 22 into which the oil is injected is filled up so that the displacement movement of the inner pipe 11 acts upward, so that the oil injected into the upper chamber portion 21 is increased. It is discharged through the fluid inlet 21a by the repulsive force of the inner pipe 11 in the limited space of the outer case 12.

이와 같이 과도한 자동차의 선회시에 발생하는 롤링량을 최대한 억제하기 위하여 차체와 쇽업소버의 연결구조에 위치한 마운팅 부시(10) 내에 가변유체 챔버(20)를 구비함으로써, 자동차 선회시 자동차 외측에 위치한 쇽업소버의 압축량을 상쇄되도록 하여 안정적인 선회 성능을 구현할 수 있도록 한다.The variable fluid chamber 20 is provided in the mounting bush 10 located in the connection structure between the vehicle body and the shock absorber in order to minimize the amount of rolling generated during excessive turning of the vehicle. By offsetting the amount of compression of the absorber, it is possible to realize stable turning performance.

이때, 도 4는 본 발명에 따른 자동차용 쇽업소버의 자세제어장치에 공급되는 유체의 제어 구성도를 나타내는 도면으로서, 평상 주행시에는 유압회로(120)의 개폐밸브(110)가 차단되어 마운팅 부시(10)가 중립상태로 완충 기능을 수행하다가 자동차가 고속으로 좌회전으로 선회시 센싱수단인 조향각 센서(130)와 휠속도 센서(140)로 고속 선회 여부 및 선회 방향을 감지하고, 이를 ECU(100)에서 판단하여 상기 마운팅 부시(10)의 가변유체 챔버(20)의 유체 주입량을 제어하게 된다.At this time, Figure 4 is a view showing the control configuration of the fluid supplied to the attitude control device of the shock absorber for automobiles according to the present invention, in the normal driving, the shut-off valve 110 of the hydraulic circuit 120 is blocked mounting mounting ( 10) while performing a shock-absorbing function in the neutral state when the car turns to the left at high speed, the steering angle sensor 130 and the wheel speed sensor 140, which senses the high speed turning and the turning direction is detected, ECU 100 By judging from the to control the fluid injection amount of the variable fluid chamber 20 of the mounting bush (10).

즉, 본 발명의 바람직한 실시예에 있어서, 첨부 도면에 도시된 바와 같이, 좌측 고속 선회시 상기 ECU(100)는 자동차의 선회 외측인 우측 개폐밸브(110)만을 개방하여 스티어링 기어박스의 유압회로(120)와 상기 마운팅 부시(10)의 하부측 챔버부(22)를 연결시키게 될 경우, 상기 하부측 챔버부(22)로 유체가 유입되고, 상부측 챔버부(21)는 유체가 배출되면서 외측의 쇽업소버의 변위가 증대되면서 자동차 의 선회시의 압축 변위를 상쇄시키게 되며 결과적으로 롤링 각도를 상쇄시키게 된다.That is, in the preferred embodiment of the present invention, as shown in the accompanying drawings, during the left high-speed turning, the ECU 100 opens only the right opening / closing valve 110, which is the outer side of the turning of the vehicle, to open the hydraulic circuit of the steering gear box ( When the lower chamber portion 22 of the mounting bush 10 is connected to the fluid 120, the fluid flows into the lower chamber 22, and the upper chamber 21 is discharged from the outside. As the displacement of the shock absorber increases, the compression displacement at the time of turning the vehicle is canceled, and as a result, the rolling angle is offset.

이때, 내측의 유압회로(120)를 차단하는 것은 차체 롤링 시 하부 서스펜션과 휠이 차체 변위에 추종하여 상방으로 들뜨는 현상을 방지하기 위함이다. At this time, the blocking of the inner hydraulic circuit 120 is to prevent the lower suspension and the wheel is lifted upward following the vehicle body displacement when rolling the vehicle body.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 않으며, 특허청구범위에서 청구된 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.Although the above has been shown and described with respect to the preferred embodiments of the present invention, the present invention is not limited to the above-described embodiment, in the technical field to which the present invention pertains without departing from the spirit of the invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such changes will fall within the scope of the claims set forth.
