Abstract
Description
본 발명은 차량의 능동형 롤 제어 장치에 관한 것으로서, 더욱 상세하게는 차량의 주행중 일어나는 롤을 제어하는 스테빌라이저 바의 기능을 효과적으로 제어할 수 있도록 한 능동형 롤 제어 장치에 관한 것이다.The present invention relates to an active roll control device for a vehicle, and more particularly, to an active roll control device for effectively controlling the function of a stabilizer bar for controlling a roll that occurs while the vehicle is running.
일반적으로 차량에는 차량의 주행시 차체가 한쪽으로 쏠리는 롤(roll) 현상을 방지하기 위하여 능동형 롤 제어 시스템이 장착되어 사용되었다.In general, the vehicle is equipped with an active roll control system in order to prevent a roll phenomenon in which the vehicle body is pulled to one side when the vehicle is driven.
종래의 능동형 롤 제어 시스템은 차량의 주행시 롤 발생에 따른 스테빌라이저 바의 강성을 유지시켜서 조종 안정성을 확보하고, 롤이 발생하지 않으면 주행시 스테빌라이저 바의 강성을 해제시켜서 승차감을 확보하였다.The conventional active roll control system secures steering stability by maintaining the rigidity of the stabilizer bar according to the roll generation when the vehicle is running, and releases the rigidity of the stabilizer bar during driving when the roll is not generated to secure the riding comfort.
그러나 이러한 종래의 능동형 롤 제어 시스템은, 차량의 롤 거동에 대하여 스테빌라이저 바의 고유 강성에 따라 차량의 자세를 유지시키는 기능을 할 뿐, 롤 거동에 대하여 실제적으로 보상을 실시하는 구성이 아니므로 차량의 롤 보상에 한계가 있는 문제점이 있다.However, such a conventional active roll control system functions to maintain the attitude of the vehicle according to the inherent stiffness of the stabilizer bar with respect to the roll behavior of the vehicle, and is not configured to actually compensate for the roll behavior. There is a problem in that there is a limit in roll compensation.
따라서, 본 발명은, 이러한 종래기술의 문제점을 해결하기 위한 것으로서, 스테빌라이저 바의 강성을 임의로 조절하는 것을 그 목적으로 한다.Accordingly, the present invention is to solve such a problem of the prior art, and its object is to arbitrarily adjust the rigidity of the stabilizer bar.
전술한 목적을 달성하기 위해, 본 발명은, 중간 부분이 차체의 크로스 멤버에 회전 가능하게 설치되고 상기 중간 부분에 대하여 구부러진 양단부들이 차륜 지지용 허브들에 각각 회전 가능하게 연결되는 스테빌라이저 바와, 상기 스테빌라이저 바의 양단부들과 상기 차륜 지지용 허브들 사이에 각각 설치되는 액추에이터를 포함하는 구성으로 되어 있다.In order to achieve the above object, the present invention provides a stabilizer bar having a middle portion rotatably installed at a cross member of a vehicle body, and both ends bent relative to the middle portion rotatably connected to wheel support hubs, respectively, An actuator is provided between both ends of the stabilizer bar and the wheel support hubs, respectively.
전술한 바와 같이, 본 발명의 차량의 능동형 롤 제어 장치에 의하면, 액추에이터의 변위에 따라 스테빌라이저 바의 강성이 임의로 적절히 조절되므로 차량의 주행시 발생하는 롤 거동에 대하여 실제적으로 보상할 수 있는 효과가 있다.As described above, according to the active roll control apparatus of the vehicle of the present invention, since the rigidity of the stabilizer bar is arbitrarily appropriately adjusted according to the displacement of the actuator, there is an effect that can actually compensate for the roll behavior generated when the vehicle is running. .
도 1은 본 발명의 실시예에 따른 차량의 능동형 롤 제어 장치의 개략도이다. 1 is a schematic diagram of an active roll control apparatus for a vehicle according to an embodiment of the present invention.

도 1은 본 발명의 실시예에 따른 차량의 능동형 롤 제어 장치의 개략도이다. 도시된 바와 같이, 본 실시예에 따른 차량의 능동형 롤 제어 장치는 스테빌라이저 바(10)와 액추에이터(20)와 회전방향 및 측방향 중력 센서(31)와 차속 센서(33)와 전자제어유닛(35)을 포함한다.1 is a schematic diagram of an active roll control apparatus for a vehicle according to an embodiment of the present invention. As shown, the active roll control apparatus for a vehicle according to the present embodiment includes a stabilizer bar 10 and an actuator 20, rotational and lateral gravity sensors 31, a vehicle speed sensor 33, and an electronic control unit ( 35).
스테빌라이저 바(10)는 중간 부분이 대략 직선이며, 이 중간 부분은 차체의 크로스 멤버(1)에 회전 가능하게 설치되어 있다. 크로스 멤버(1) 상에는 스테빌라이저 바 하우징(3)이 설치되어 있으며, 스테빌라이저 바 하우징(3)의 내부에는 베어링(4)이 장착되어 있다. 스테빌라이저 바(10)는 스테빌라이저 바 하우징(3)의 베어링(4)에 삽입되어 스테빌라이저 바 하우징(3)에 회전 가능하게 설치된다.The stabilizer bar 10 has an intermediate portion of a substantially straight line, and the intermediate portion is rotatably provided at the cross member 1 of the vehicle body. The stabilizer bar housing 3 is provided on the cross member 1, and the bearing 4 is attached to the inside of the stabilizer bar housing 3. The stabilizer bar 10 is inserted into the bearing 4 of the stabilizer bar housing 3 and rotatably installed in the stabilizer bar housing 3.
스테빌라이저 바(10)의 양단부들은 중간 부분에 대하여 대략 45°로 구부러져 있으며, 이 스테빌라이저 바(10)의 양단부들은 차륜 지지용 허브(5)들에 각각 회전 가능하게 연결되어 있다.Both ends of the stabilizer bar 10 are bent at approximately 45 ° with respect to the middle part, and both ends of the stabilizer bar 10 are rotatably connected to the wheel supporting hubs 5, respectively.
액추에이터(20)는 스테빌라이저 바(10)의 양단부들과 차륜 지지용 허브(5)들 사이에 각각 설치된다. 액추에이터(20)는 본체(21) 내에서 로드(23)가 직선 운동하도록 구성되어 있다. 액추에이터(20)의 본체(21)는 차륜 지지용 허브(5)에 회전 가능하게 설치되고, 액추에이터(20)의 로드(23)는 스테빌라이저 바(10)의 단부에 회전 가능하게 설치된다.The actuator 20 is installed between both ends of the stabilizer bar 10 and the wheel supporting hubs 5, respectively. The actuator 20 is comprised so that the rod 23 may linearly move in the main body 21. The main body 21 of the actuator 20 is rotatably installed at the wheel support hub 5, and the rod 23 of the actuator 20 is rotatably installed at the end of the stabilizer bar 10.
차륜 지지용 허브(5)에는 회전체(6)가 설치되고, 이 차륜 지지용 허브(5)의 회전체(6)에 액추에이터(20)의 본체(21)가 회전 가능하게 연결된다. 스테빌라이저 바(10)의 단부에는 회전체(11)가 설치되고, 이 스테빌라이저 바(10)의 회전체(11)에 액추에이터(20)의 로드(23)가 회전 가능하게 연결된다. 차륜 지지용 허브(5)의 회전체(6)의 기술 구성, 스테빌라이저 바(10)의 회전체(11)의 기술 구성, 및 차륜 지지용 허브(5)의 회전체(6)에 액추에이터(20)의 본체(21)가 회전 가능하게 연결되고 스테빌라이저 바(10)의 회전체(11)에 액추에이터(20)의 로드(23)가 회전 가능하게 연결되는 기술 구성은 당업자에게 공지의 기술이므로 도면에서는 이에 대하여 간략하게 도시하기로 한다.The wheel supporting hub 5 is provided with a rotating body 6, and the main body 21 of the actuator 20 is rotatably connected to the rotating body 6 of the wheel supporting hub 5. A rotating body 11 is provided at the end of the stabilizer bar 10, and the rod 23 of the actuator 20 is rotatably connected to the rotating body 11 of the stabilizer bar 10. The technical configuration of the rotating body 6 of the wheel supporting hub 5, the technical configuration of the rotating body 11 of the stabilizer bar 10, and the rotating body 6 of the wheel supporting hub 5 are provided with an actuator ( The technical configuration in which the main body 21 of the 20 is rotatably connected and the rod 23 of the actuator 20 is rotatably connected to the rotating body 11 of the stabilizer bar 10 is known to those skilled in the art. In the drawings it will be briefly shown.
회전방향 및 측방향 중력 센서(31)는 회전방향 및 측방향 움직임을 감지하며, 차속 센서(33)는 차량의 속도를 감지한다. 액추에이터(20)의 로드(23)의 변위는 회전방향 및 측방향 중력 센서(31)와 차속 센서(33)로부터의 신호에 따라 전자제어유닛(ECU, 35)에 의해 제어된다.The rotation direction and the lateral gravity sensor 31 detects the rotation direction and the lateral movement, and the vehicle speed sensor 33 detects the speed of the vehicle. The displacement of the rod 23 of the actuator 20 is controlled by the electronic control unit ECU 35 in accordance with the signals from the rotational and lateral gravity sensors 31 and the vehicle speed sensor 33.
회전방향 및 측방향 중력 센서(31)와 차속 센서(33)로부터의 신호에 따라 전자제어유닛(35)에서 롤 발생량을 계산하여 롤 발생량 만큼 액추에이터(20)의 로드(23)를 변위시키면 스테빌라이저 바(10)의 양단부가 스테빌라이저 바 하우징(3)을 중심으로 회전하게 되므로 스테빌라이저 바의 강성이 임의로 적절히 조절된다. 이렇게 스테빌라이저 바의 강성이 임의로 적절히 조절됨에 따라 차량의 주행시 발생하는 롤 거동에 대하여 실제적으로 보상할 수 있다.The electronic control unit 35 calculates the roll generation amount in accordance with the signals from the rotational and lateral gravity sensors 31 and the vehicle speed sensor 33, and displaces the rod 23 of the actuator 20 by the roll generation amount. Since both ends of the bar 10 rotate about the stabilizer bar housing 3, the rigidity of the stabilizer bar is arbitrarily appropriately adjusted. Thus, as the rigidity of the stabilizer bar is arbitrarily appropriately adjusted, it is possible to actually compensate for the roll behavior generated when the vehicle is driven.
