Description
본 발명은 차량용 롤각 조절장치에 관한 것으로, 보다 상세하게는 차량의 현가장치에 구비되어 롤링을 감소시키는 차량용 롤각 조절장치에 관한 것이다.The present invention relates to a roll angle adjusting device for a vehicle, and more particularly, to a roll angle adjusting device for a vehicle provided in the suspension of the vehicle to reduce rolling.
일반적으로 차량에서 스테빌라이져 바는 차량의 앞 또는 뒤의 현가장치에 장착되어 차체의 기울어짐을 줄이기 위한 것이다. 이러한 스테빌라이져 바는 일정한 충격에 비틀어질 수 있는 탄성체로 이루어지며, 좌,우바퀴의 움직임에 차이가 있을 때만 작용한다.In general, a stabilizer bar in a vehicle is mounted on a suspension device in front of or behind a vehicle to reduce the inclination of the vehicle body. The stabilizer bar is made of an elastic body that can be twisted to a certain impact, and works only when there is a difference in the movement of the left and right wheels.
도 1은 종래기술에 따른 차량용 스테빌라이져를 도시한 사시도로써, 프론트(front) 현가장치 중 위시본 타입(wishbone type)을 도시하고 있다.1 is a perspective view showing a vehicle stabilizer according to the prior art, showing a wishbone type of a front suspension.
우선, 프론트 현가장치의 구성은 어퍼암 및 로어암(upper arm & lower arm), 프론트 쇼크 압쇼버(front shock absorber)와 스프링(spring), 피봇링크, 스테빌라이져 바(stabilizer bar, 또는 스테빌라이져 축(Stabilizer Shaft)) 및 스트럿어셈블리 등으로 이루어진다.First, the configuration of the front suspension consists of upper and lower arms, front shock absorbers and springs, pivot links, stabilizer bars, or stabilizer shafts. Shaft)) and strut assembly.
도면에 도시되어 있지 않지만 상기 어퍼암과 로우암은 조향너클(8)과 차체(9)를 연결한다.Although not shown in the figure, the upper arm and the lower arm connect the steering knuckle 8 and the vehicle body 9.
그리고, 코일스프링(5)과 쇽업쇼버(4)는 스트럿어셈블리(3)에 연결되어 도로주행 조건상 적은 하중의 힘이 휠(wheel)로 전달될 경우에 하중과 진동을 흡수시킨다. 여기서 쇽업쇼버(4)는 유압식 텔레스코픽 쇽업쇼버(Telescopic shock-absorber)가 사용된다.In addition, the coil spring 5 and the shock absorber 4 are connected to the strut assembly 3 to absorb the load and the vibration when a small load force is transmitted to the wheel under the road driving conditions. Here, the shock absorber 4 is a hydraulic telescopic shock absorber (Telescopic shock-absorber) is used.
또한 스테빌라이져 바(6)는 피봇링크(7)로 중간부분이 고정되고 양측 스트럿어셈블리(3)에 링크부재를 개재한 상태로 연결된다.In addition, the stabilizer bar 6 is connected to the intermediate portion is fixed to the pivot link (7) with the link member through the strut assembly (3) on both sides.
특히, 스테빌라이져 바(6)는 비틀림 가능한 탄성재질로 이루어지며, 좌우바퀴의 움직임 차이가 있을 때만 작용한다. In particular, the stabilizer bar 6 is made of a twistable elastic material, and works only when there is a difference in movement of the left and right wheels.
구체적으로, 스테빌라이져 바(6)는 차량이 선회할 때 원심력 때문에 기울어지거나 옆으로 흔들리는 현상을 방지하기 위하여 앞바퀴 양축에 설치하여 좌우 어느 한쪽의 바퀴가 상하로 움직였을 경우, 자체 탄성력에 의하여 반대쪽의 바퀴를 같은 방향으로 유도하므로서 좌,우 바퀴의 움직임을 같게 하는 작용을 하여 차체의 기울기, 즉 롤각(roll angle)을 최소로 하고 차체의 롤(Roll)현상을 억제하여 승차감 및 차체를 안정되게 한다.Specifically, the stabilizer bar 6 is installed on both front wheels to prevent the tilting or sideways shaking due to the centrifugal force when the vehicle is turning. By guiding in the same direction, the left and right wheels have the same motion, thereby minimizing the inclination of the vehicle body, that is, the roll angle, and suppressing the roll phenomenon of the vehicle body to stabilize the ride and the vehicle body.
또한, 좌우 바퀴가 동시에 충격 또는 리바운드 할 때에는 스테빌라이져 바(6)는 작용하지 않는다.In addition, the stabilizer bar 6 does not work when the left and right wheels simultaneously impact or rebound.
하지만, 종래의 스테빌라이져 바는 비교적 높은 롤강성(roll stiffness)을 요구하는 하중이 무거운 대형 차량의 경우, 통상적인 스테빌라이져 바의 굵기보다 굵기를 더 증가시켜야 하기 때문에 차량의 하중이 동반 상승하며, 제조원가가 증가하는 문제점이 있었다.However, in the case of a large vehicle with a heavy load requiring a relatively high roll stiffness, the conventional stabilizer bar has to increase its thickness more than the thickness of a conventional stabilizer bar, thereby increasing the load of the vehicle and manufacturing cost. There was an increasing problem.
아울러, 노면(路面)에 의해 차량의 좌우바퀴에 위상차가 비교적 클 시에는 스테빌라이져 바가 없는 차량보다 오히려 스테빌라이져 바를 설치한 차량의 고유진동수가 높아지고 전달이득(gain) 또한 높아져서 진동절연성이 나빠지는 문제점이 있었다.In addition, when the phase difference between the left and right wheels of the vehicle is relatively large due to the road surface, the natural frequency of the vehicle having the stabilizer bar is increased rather than the vehicle without the stabilizer bar. .
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 스테빌라이져 바의 하중을 경량화시켜 차체 하중을 감소시키고, 차량의 고유진동수를 현저히 낮추고 전달이득(gain) 또한 하강시켜서 진동절연성을 우수하게 하며, 차량의 선회 가속도에 따라 롤강성(roll stiffness)을 수시로 변화시켜 롤각을 조절하는 차량용 롤각 조절장치를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, the weight of the stabilizer bar to reduce the weight of the vehicle body, significantly lower the natural frequency of the vehicle and also lower the transmission gain (gain) to excellent vibration insulation, It is an object of the present invention to provide a roll angle adjusting device for a vehicle that adjusts the roll angle by changing roll stiffness from time to time according to the turning acceleration of the vehicle.

한편, 노면(路面)에 의해 차량의 좌우바퀴에 위상차가 있다거나 차량이 선회하게 되면 본 발명의 스테빌라이져 바가 비틀림 동작하는데, 본 발명에 따른 스테빌라이져 바의 동작은 도 2 내지 도 4에 도시된 바와 같다.On the other hand, when there is a phase difference in the left and right wheels of the vehicle due to the road surface or the vehicle is turning, the stabilizer bar of the present invention is torsionally operated, the operation of the stabilizer bar according to the present invention is as shown in Figs. .
우선, 노면(路面)에 의해 차량의 좌우바퀴에 위상차가 있다거나 차량이 선회하게 되면, 감지부인 조향각 감지센서(12)와 주행속도 감지센서(13)가 차량의 조향각과 주행속도의 정보를 마이컴(14)으로 인가한다.First, when there is a phase difference between the left and right wheels of the vehicle or the vehicle is turned due to the road surface, the steering angle sensor 12 and the traveling speed sensor 13, which are detection units, input information about the steering angle and the driving speed of the vehicle. (14).
마이컴(14)은 감지부의 정보를 받아서 롤각의 크기를 산출하게 되며, 산출된 롤각으로 액츄에이터(15)를 가동시킨다. 여기서, 차량의 롤각(roll angle)은 이론적으로 롤모멘트(roll moment)/롤강성(roll stiffness)으로 산출할 수 있으며, 마이컴(14)에서 산출된 롤각을 스테빌라이져 바(10,11)에 적용하기 위해서는 액츄에이터(15)를 이용하여 스테빌라이져 바(10,11)의 비틀림량을 변화시켜야 한다.The microcomputer 14 receives the information of the sensing unit, calculates the size of the roll angle, and operates the actuator 15 at the calculated roll angle. Here, the roll angle of the vehicle can theoretically be calculated by roll moment / roll stiffness, and applying the roll angle calculated by the microcomputer 14 to the stabilizer bars 10 and 11. In order to change the amount of torsion of the stabilizer bars 10 and 11 using the actuator 15.
그리고, 마이컴(14)에는 차량의 선회 횡가속도에 따라 목표 롤각을 기저장하고 이 롤각을 얻기 위한 롤강성은 스테빌라이져 바(10,11)의 비틀림각을 변화시킴으로서 얻을 수 있다. 상기 마이컴(14)은 감지부의 정보를 지속적으로 제공받아 액츄에이터(15)를 연속적으로 제어할 수 있으며, 반면 마이컴(14) 내에 미리 정해진 단계에 따라 액츄에이터(15)가 작동되도록 비연속적으로 제어할 수도 있다.The microcomputer 14 stores the target roll angle according to the turning lateral acceleration of the vehicle, and the roll stiffness for obtaining the roll angle can be obtained by changing the twist angles of the stabilizer bars 10 and 11. The microcomputer 14 may continuously receive the information of the sensing unit to continuously control the actuator 15, whereas the microcomputer 14 may control the actuator 15 to be operated continuously according to a predetermined step in the microcomputer 14. have.
상기 액츄에이터(15)는 마이컴(14)의 신호로 그 축(16)이 회전하며, 축(16)은 다시 유성기어트레인(18)을 동작시키게 된다.The actuator 15 is rotated by the signal of the microcomputer 14, the shaft 16 is rotated, the shaft 16 is to operate the planetary gear train 18 again.
유성기어트레인(18)의 동작은 액츄에이터(15)의 축(16), 즉 웜기어와 치합되어 회전력을 전달받는 제 1태양기어(19)와, 제 1태양기어(19)의 회동으로 일측에 위치한 스테빌라이져 바(10)가 일방향으로 회전하면서 비틀어지게 된다. 스테빌라이져 바(10)의 비틀림에 의해 제 2태양기어(20)가 회동하고, 제 2태양기어(20)의 회동과 동시에 그 외주연에 구비된 유성기어들(21,22,23)이 회동한다.The operation of the planetary gear train 18 is located at one side by the rotation of the first sun gear 19 and the first sun gear 19 which are engaged with the shaft 16 of the actuator 15, that is, the worm gear, to receive the rotational force. The stabilizer bar 10 is twisted while rotating in one direction. The second sun gear 20 is rotated by the twisting of the stabilizer bar 10, and the planetary gears 21, 22, 23 provided at the outer periphery of the second sun gear 20 are rotated at the same time. .
다시 유성기어들(21,22,23)은 그 외주연에 구비된 링기어(25)를 회동시키고, 상기 링기어(25)와 일체로 형성된 타측의 스테빌라이져 바(11)도 동시에 회전하면서 비틀어지게 된다.The planetary gears 21, 22, and 23 rotate the ring gear 25 provided at the outer circumference thereof, and the other stabilizer bar 11 formed integrally with the ring gear 25 is also twisted while rotating at the same time. do.
여기서 상기 액츄에이터(15)가 구동하면 유성기어트레인(18)에 구비된 각도센서(17)가 회전각을 피드백(feed back)하여 목표하는 회전각까지 작동하였는지 마이컴(14)에 전기적 신호로 전달하고, 마이컴(14)은 각도센서(17)의 정보를 제공받아 유성기어트레인(18)이 목표하는 회전각까지 작동하지 않았을 시에는 다시 액츄에이터(15)를 가동하여 유성기어트레인(18)을 동작시키도록 한다.In this case, when the actuator 15 is driven, the angle sensor 17 provided in the planetary gear train 18 feeds back the rotation angle and transmits the rotation angle as an electrical signal to the microcomputer 14 as to whether it operates to the target rotation angle. The microcomputer 14 receives the information of the angle sensor 17 to operate the planetary gear train 18 by operating the actuator 15 again when the planetary gear train 18 does not operate until the desired rotation angle. To do that.
본 발명은 스테빌라이져 바에 롤각 조절장치를 설치하기 때문에 높은 롤강성(roll stiffness)을 요구하는 하중이 무거운 대형 차량의 경우에도 통상적인 스테빌라이져 바의 굵기를 사용하거나 그 보다 더 가는 굵기의 스테빌라이져 바를 사용하므로, 차량의 하중을 현저히 하강시킬 수 있으며 제조원가를 감소하는 효과가 있다.In the present invention, since the roll angle adjusting device is installed in the stabilizer bar, even in a heavy vehicle requiring a high roll stiffness, the stabilizer bar of a conventional stabilizer bar or a thinner thickness is used. The load on the vehicle can be significantly lowered and the manufacturing cost is reduced.
아울러, 노면(路面)에서 좌우의 위상차가 비교적 클 시에도 롤각 조절장치를 갖는 스테빌라이져 바에 의해 차량의 고유진동수를 현저히 낮추고 전달이득(gain) 또한 하강시켜서 진동절연성이 우수한 장점이 있다.In addition, even when the phase difference between the left and right on the road surface is relatively large, the stabilizer bar having the roll angle adjusting device significantly lowers the natural frequency of the vehicle and also lowers the transmission gain, thereby providing excellent vibration insulation.
추가적으로, 차량의 선회 횡가속도에 따라 롤강성을 변화시키므로, 운전자의 취향에 따른 롤각을 제공할 수 있어서 차량의 주행을 역동적으로 할 수 있다.In addition, since the roll stiffness is changed according to the turning lateral acceleration of the vehicle, it is possible to provide a roll angle in accordance with the driver's taste, thereby making the driving of the vehicle dynamic.
