Description
본 발명은 능동 제어 부시 시스템에 관한 것으로, 보다 상세하게는 가해지는 외력을 능동적으로 제어할 수 있도록 된 능동 제어 부시 시스템 에 관한 것이다.The present invention relates to an active control bushing system, and more particularly, to an active control bushing system capable of actively controlling an external force applied thereto.
일반적으로 차량은 주행 중 노면으로부터 지속적인 충격을 받게 되고 이러한 충격을 보다 효과적으로 흡수·완충하여 승차감을 향상하도록 통상적으로 연결이나 결합부위에서는 부시(Bush)를 사용하게 되는데, 이러한 부시는 도 1에 도시된 바와 같이 중심에 타부분과 결합되는 코어축(2)을 감싸면서 그 외부로 스틸재의 외통(도시되어 있지 않음)에 의해 감싸인 고무재질의 바디부(1)로 이루어지되, 이 바디부(1)에는 그 충격 흡수율을 높이도록 빈 공간인 개구홀(3)을 형성하게 된다.In general, a vehicle receives a continuous shock from the road surface while driving, and generally uses a bush at a connection or coupling part to more effectively absorb and buffer such an impact to improve riding comfort. As it wraps around the core shaft (2) coupled to the other part in the center and made of a rubber body body portion (1) wrapped by an outer cylinder (not shown) of the steel material, the body portion (1) ), An opening hole 3, which is an empty space, is formed to increase the shock absorption rate.
여기서, 상기 바디부(1)의 재질은 사용되는 목적과 방법에 따라서 다양한 것이 사용될 수 있으나 주로 고무재질의 것이 사용됨은 물론 상기 바디부(1)에 형성되는 개구홀(3)은 사용되는 목적과 방법에 따라서 가장 적합한 형상을 이루게 되지만, 일단 그 형상이 정해진 후에는 항상 동일한 물성치를 제공하게 된다.Here, the material of the body portion 1 may be used in various ways depending on the purpose and method used, but mainly of rubber material is used as well as the opening hole (3) formed in the body portion 1 is used and According to the method, the most suitable shape is achieved, but once the shape is defined, the same physical properties are always provided.
그러나, 이와 같이 고무재질의 바디부(1)로 이루어진 마운팅 부시는 그 형상이 특정한 방향에 대해서 미리 설정된 결과에 의해 형성되는 것이므로, 실질적인 차량운행에 있어서 발생되는 다양한 외력에 대해서는 효과적인 진동절연 및 충격흡수가 이루어지지 못하는 문제점이 있는 것이다.However, since the mounting bush made of the rubber body 1 is formed by a predetermined result in a specific direction, it is effective for the various external forces generated in the actual vehicle driving, and thus is effective for vibration insulation and shock absorption. There is a problem that can not be achieved.
즉, 도 2에 도시된 바와 같이 상기 바디부(1)에 개구홀(3)이 Y축 방향을 따라 수직하게 형성되면 Y축 방향으로 가해지는 외력(Fy)에 대해서 충분한 완충효과를 나타내지만 X축 방향으로 가해지는 외력(Fx)에 대해선 완충효과를 나타내지 못하는 단점이 있고 이와 같이, 특정 방향의 외력에 대한 불충분한 완충효과는 그 크기와 작용방향이 차량의 운행상태에 따라 끊임없이 변화하는 외력에 대해 항상 최적의 승차감을 제공할 수 없는 단점이 있게 된다.That is, as shown in FIG. 2, when the opening hole 3 is vertically formed along the Y-axis direction in the body part 1, sufficient buffering effect is exerted on the external force Fy applied in the Y-axis direction. There is a disadvantage in that it does not exhibit a buffering effect on the external force (Fx) applied in the axial direction. Thus, an insufficient buffering effect on the external force in a specific direction is due to the external force constantly changing in size and direction of operation depending on the driving condition of the vehicle. There is a disadvantage that can not always provide the optimum ride comfort.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량의 운행중에 변화하는 하중의 작용상태에 따라서 능동적으로 그 충격흡수 및 진동절연 작용을 이루어 계속적으로 변화하는 차량의 하중상태에 대해 항상 최적의 댐핑 기능을 수행함은 물론 안정된 승차감을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above, and is optimally suited to a constantly changing load state by actively performing its shock absorbing and vibration isolating action according to the action state of a load that changes during operation of the vehicle. The purpose of the damping function as well as to provide a stable ride.

여기서, 상기 인너봉(4)은 바디부(1)의 물성치를 변경시키도록 소정간격(A,C)의 위치에서 일체로 돌출 형성됨과 더불어 소정폭(B,D)을 갖도록 제1·2리브(4a,4b)가 형성되되, 이 제1·2리브(4a,4b)는 상·하·좌·우 4방향으로 돌출 형성되어져 상기 코어축(2)의 삽입홀(2a)을 통해 결합되어진다.Here, the inner rod 4 is formed to protrude integrally at the positions of the predetermined intervals A and C so as to change the physical properties of the body portion 1, and the first and second ribs to have the predetermined widths B and D. 4a and 4b are formed, and the first and second ribs 4a and 4b protrude in four directions in the up, down, left, and right directions, and are coupled through the insertion holes 2a of the core shaft 2. Lose.
또한, 상기 제어수단(10)은 도 4에 도시된 바와 같이 바디부(1)에 삽입되어 그 변형을 측정하는 스트레인 게이지로 이루어진 센서(11)와, 이 센서(11)의 측정값에 따라 물성치를 변화시켜야 하는 바디부(1)의 위치를 결정하는 제어기(12), 이 제어기(12)의 신호에 의해 구동되는 모터로 이루어진 구동기(13)에 의해 작동되어 인너봉(4)의 위치를 변경하는 액튜에이터로 이루어진 작동기(14)로 구성되어 진다.In addition, as shown in FIG. 4, the control means 10 includes a sensor 11 made of a strain gauge inserted into the body 1 and measuring deformation thereof, and a physical property value according to the measured value of the sensor 11. It is operated by the controller 12 which determines the position of the body part 1 which should be changed, and the driver 13 which consists of a motor driven by the signal of this controller 12, and changes the position of the inner rod 4. It consists of an actuator (14) consisting of an actuator.
여기서, 상기 센서(10)는 통상 하중이 작용하는 방향 즉, 외력이 전달되는 X축과 Y축 방향으로 구비되어짐은 물론이다.Here, the sensor 10 is usually provided in the X-axis and Y-axis direction in which the load acts, that is, the external force is a matter of course.
이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.
본 발명은 차량의 운행상태에 따라서 실시간으로 다양한 크기와 방향의 외력이 마운팅 부시의 바디부(1)로 전달되거나 또는 큰 변화가 없는 외력이 전달되더라도 이를 충분히 완충하게 되는데 먼저, 가해지는 외력이 크게 변화하지 않는 경우에는 상기 바디부(1)도 그 변형이 거의없고 즉, 서로 어느 쪽으로도 치우치지 않고 연결된 물체의 사이를 일정하게 지지하고 있는 상태이므로 제어수단(10)의 센서(11)의 변형에 따른 측정 신호가 미약하여 제어기(12)가 바디부91)의 물성치 변화의 필요성을 못 느끼게 되면 상기 바디부(1)의 코어축(2)에 결합된 인너봉(4)의 위치도 변화하지 않게 된다.According to the present invention, an external force of various sizes and directions is transmitted to the body portion 1 of the mounting bush in real time according to the driving state of the vehicle, or fully buffered even if an external force without large change is transmitted. If it does not change, the body part 1 is also hardly deformed, i.e., it is in a state of constantly supporting the connected objects without biasing each other, so that deformation of the sensor 11 of the control means 10 When the measurement signal is weak and the controller 12 does not feel the necessity of changing the physical properties of the body 91, the position of the inner rod 4 coupled to the core shaft 2 of the body 1 does not change. Will not.
그러나, 이와 같은 정적인 상태로부터 차량의 운행에 따라 실시간으로 변화하는 바디부(1)에 각각 연결된 물체의 운동상태에 따라서 바디부(1)를 크게 변형시키게 되면, 이와 같은 바디부(1)의 변형상태를 제어수단(10)의 센서(11)에서 측정하게 되고, 이와 같이 측정된 바디부(1)의 변형 값이 제어기(12)의 설정된 임계값을 초과하게 될때에는 상기 제어수단(10)의 작동에 의해 바디부(1)의 물성치가 전달되는 외력을 충분히 완화시킬 수 있도록 변화시켜주게 된다.However, when the body part 1 is greatly deformed according to the motion state of the object connected to the body part 1 which changes in real time according to the driving of the vehicle from such a static state, the body part 1 of the body part 1 The deformation state is measured by the sensor 11 of the control means 10, and when the deformation value of the body part 1 measured in this way exceeds the set threshold value of the controller 12, the control means 10 By the operation of the physical properties of the body (1) is to be changed to sufficiently mitigate the external force transmitted.
즉, 상기 바디부(1)의 물성치 변화는 외력이 가해진 방향에 따라 상응하도록 인너봉(4)의 위치를 변경하게 되는데 즉, 도 5에 도시된 바와 같이 상기 바디부(1)의 변형이 가해진 외력(Fy)에 의해 Y축 방향으로 크게 이루어지게 되면 인너봉(4)의 제1·2리브(4a,4b)의 위치를 각각 바디부(1)의 A구간과 C구간에 위치되도록 상기 제어기(12)가 모터(13)와 액튜에이터(14)를 작동시키게 된다.That is, the change in the physical properties of the body portion 1 changes the position of the inner rod 4 to correspond to the direction in which the external force is applied, that is, as shown in Figure 5 the deformation of the body portion 1 is applied The controller is arranged so that the position of the first and second ribs 4a and 4b of the inner rod 4 is located in the A section and the C section of the body portion, respectively, when the large force is made in the Y axis direction by the external force Fy. 12 causes the motor 13 and actuator 14 to operate.
또한, 상기 바디부(1)의 변형이 가해진 외력(Fx)에 의해 X축 방향으로 크게 이루어지게 되면 인너봉(4)의 제1·2리브(4a,4b)의 위치를 각각 바디부(1)의 B구간과 D구간에 위치되도록 상기 제어기(12)가 구동기(13)와 작동기(14)를 작동시키게된다.In addition, when the deformation of the body portion 1 is made large in the X-axis direction by the external force Fx applied thereto, the positions of the first and second ribs 4a and 4b of the inner rod 4 are respectively determined. The controller 12 operates the actuator 13 and the actuator 14 so as to be located in the section B and the section D).
이와 같이, 상기 제어수단(10)의 센서(11)에서 측정된 바디부(1)의 변형 값을 매개로 제어기(11)에서 계산된 결과에 따라 발생되는 제어신호에 따라 구동기(13)와 작동기(14)를 제어하여 인너봉(4)의 리브(4a,4b)위치를 적절히 변경시켜 바디부(1)의 물성치를 가해진 외력에 상응하도록 변화시키면서 댐핑기능을 수행하게 되는 것이다.즉, 본원의 마운팅 부시는 바디부(1)의 물성 변화 필요시 상기 제어수단(10)으로 이동되는 인너봉(4)의 1·2리브(4a,4b)가 코어축(2)의 내경에서 이동되고, 상기 1·2리브(4a,4b)의 위치가 바디부(1)의 개구홀(3)부위에 위치되는가 또는 위치되지 않느가를 통해 바디부(1)의 물성치를 변화시키도록 된 것으로서, 이는 상기 바디부(1)의 개구홀(3)이 인너봉(4)에서 소정폭(B,D)을 두어 서로 떨어뜨려 형성시키는 소정간격(A,C)에 형성되고 이로 인해, 상기 인너봉(4)의 1·2리브(4a,4b)가 코어축(2)에서 위치 이동될 때 상기 개구홀(3)이 형성된 소정간격(A,C)에 위치될 때에는 바디부(1)의 변형이 크지만 상기 소정간격(A,C)에 위치지 않을 때에는 바디부(1)의 변형이 상대적으로 작아지고 이에 따라, 상기 바디부(1)의 물성치가 인너봉(4)의 1·2리브(4a,4b)위치 이동에 따라 변화되도록 이루어짐을 알 수 있는 것이다.As such, the actuator 13 and the actuator according to the control signal generated according to the result calculated by the controller 11 through the deformation value of the body portion 1 measured by the sensor 11 of the control means 10. (14) is controlled to appropriately change the position of the ribs 4a and 4b of the inner rod 4 to perform a damping function while changing the physical properties of the body 1 to correspond to the applied external force. Mounting bush is a one-two rib (4a, 4b) of the inner rod (4) which is moved to the control means 10 when the physical properties of the body (1) needs to be moved in the inner diameter of the core shaft (2), The physical properties of the body part 1 are changed through whether the position of the 1/2 ribs 4a and 4b is located at the opening hole 3 of the body part 1 or not. The opening hole 3 of the body portion 1 is formed at predetermined intervals A and C to form a predetermined width (B, D) apart from each other in the inner rod (4), thereby When the 1/2 ribs (4a, 4b) of the inner rod (4) is positioned at the predetermined interval (A, C) formed with the opening hole 3 when the position moves on the core shaft (2) When the deformation of 1) is large but is not located at the predetermined intervals A and C, the deformation of the body portion 1 is relatively small, and accordingly, the physical properties of the body portion 1 are increased. It can be seen that the 1/2 rib (4a, 4b) is made to change as the position moves.
이상 설명한 바와 같이 본 발명에 의하면, 차량의 운행중에 변화하는 하중의 작용상태에 따라서 능동적으로 그 충격흡수 및 진동절연의 작용이 이루어질 수 있도록 함으로써, 차량의 계속적으로 변화하는 하중상태에 따라 최적의 댐핑 기능을 수행하는 효과가 있게 된다.As described above, according to the present invention, the shock absorption and the vibration insulation can be actively performed according to the action state of the load that changes during the operation of the vehicle, thereby optimal damping according to the continuously changing load state of the vehicle. The effect is to perform the function.
