본 발명은 전자석을 이용한 멀티링크 현가장치 가변 토우시스템에 관한 것으로서, 더욱 상세하게는 전자석들 사이의 발생하는 인력과 척력을 이용하여 토우 변화량을 조절할 수 있는 전자석을 이용한 멀티링크 현가장치 가변 토우시스템에 관 한 것이다.The present invention relates to a multi-link suspension variable tow system using an electromagnet, and more particularly, to a multi-link suspension variable tow system using an electromagnet capable of adjusting the amount of tow variation using manpower and repulsive force generated between electromagnets. It is a tube.

차량에 있어서의 현가장치(Suspension)는, 차체와 휠 사이에 존재하며, 이 두 강체를 하나 혹은 다수의 링크를 이용하여 연결하여 주는 장치로서, 트레일링 암과 너클, 컨트롤 암 등으로 구성되어 있다.Suspension in a vehicle exists between a vehicle body and a wheel, and connects these two rigid bodies using one or more links. The suspension is composed of a trailing arm, a knuckle and a control arm. .

이러한 현가장치는 첫째, 차량의 주행중에 발생하는 노면의 불규칙한 입력을 효과적으로 차단하여 탑승자의 안락한 승차감을 제공하고, 둘째, 운전자의 운전 행위 및 노면의 굴곡에 의해 발생된 차체의 흔들림을 적절히 제어하여 운전 편의성을 제공하여야 하며, 셋째, 불규칙한 노면의 주행시 타이어 접지면에서의 수직 하중을 적절한 수준으로 유지하여 선회, 제동구동시 차량의 안정성을 확보하여야 하다는 기본 조건을 만족시켜야만 한다.Such a suspension device firstly effectively blocks the irregular input of the road surface generated while driving the vehicle to provide a comfortable riding comfort of the occupant, and secondly, appropriately controls the shaking of the vehicle body caused by the driver's driving behavior and the curvature of the road surface. Convenience should be provided, and third, the basic condition that the vertical load on the tire ground plane should be maintained at an appropriate level when driving on irregular roads should be satisfied to ensure the stability of the vehicle when turning and braking.

그러나 종래의 멀티링크 서스펜션의 토우변화 특성 제어는 주로 부시의 강성배분과 서스펜션 지오메트리에 의해 결정된다. 즉, 부시의 강성 배분에 의해 토우 제어량을 크게 하면 부시의 변화량이 커지게 되고 이에 부시의 내구성이 저하되는 문제점이 생긴다. However, the control of the toe change characteristic of the conventional multilink suspension is mainly determined by the stiffness distribution of the bush and the suspension geometry. In other words, when the toe control amount is increased by the rigid distribution of the bush, the change amount of the bush increases, and thus the durability of the bush is lowered.

또한, 토우변화가 미세한 범위 내에서 발생하기 때문에 정밀한 제어가 어려울 뿐만 아니라 서스펜션 지오메트리를 이용하여 토우변화를 제어할 경우는 토우변화 특성에 맞게 각각의 링크를 배치해야 하기 때문에 레이아웃 상에 문제가 생길 수 있는 문제점 있었다. In addition, because the toe change occurs within a minute range, it is difficult to control precisely, and when the toe change is controlled by the suspension geometry, each link must be arranged according to the toe change characteristic, which may cause problems in layout. There was a problem.

또한, 기존의 시스템에 유압을 이용하여 링크를 조절하는 경우는 정밀한 제어는 가능하나 비용과 중량, 레이아웃의 문제가 발생하게 된다. In addition, in the case of adjusting the link using hydraulic pressure in the existing system, precise control is possible, but problems of cost, weight, and layout occur.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 후륜과, 상기 후륜에 결합되고 상부로는 상부결합부가 측면에는 상, 하결합부가 형성된 너클과, 상기 너클의 상부결합부와 결합하고 전후의 힘을 받는 회전로드와, 상기 너클의 상, 하결합부와 대응하는 위치에 상, 하 결합부가 측면에 형성되는 서브프레임과, 상기 너클의 상, 하결합부와 서브프레임의 상, 하결합부 사이에 개재되는 로우링크로 구성되는 토우시스템에 있어서, 상기 서브프레임의 상, 하결합부로 각각의 전자석이 장착되고 상기 로우링크의 길이방향으로는 코일이 마련되는 것을 특징으로 한다. The present invention has been made in order to solve the above problems, the rear wheel, and the upper wheel is coupled to the rear wheel and the upper coupling portion on the side, the upper and lower knuckles formed on the side, and the upper coupling portion of the knuckle and the front and rear Rotating rod subjected to the force of the, the sub-frame in which the upper and lower coupling portion is formed on the side at the position corresponding to the upper and lower coupling portion of the knuckle, the upper and lower coupling of the upper, lower coupling portion and the subframe In the tow system composed of a low link interposed between the portions, each electromagnet is mounted to the upper and lower coupling portions of the subframe, characterized in that the coil is provided in the longitudinal direction of the low link.

멀티링크 서스펜션의 토우장치(1)는 도시된 도 1과 같이 후륜(100)과, 상기 후륜(100)에 결합하고 상부로는 상부결합부(220)가 측면에는 상, 하결합부(240, 260)가 형성되는 너클(200)과, 상기 너클(200)의 상, 하결합부(240, 260)와 대응되게 상, 하결합부(320, 340)가 측면에 형성되는 서브프레임(300)과, 상기 너클(200)의 상, 하결합부(240, 260)와 서브프레임(300)의 상, 하결합부(320, 340) 사이에 개재되는 로우링크(420, 440)와, 상기 너클(20)의 상부결합부(220)에 결합하는 회전로드(500)로 구성된다. Tow device 1 of the multi-link suspension is coupled to the rear wheel 100 and the rear wheel 100, as shown in Figure 1 and the upper coupling portion 220 to the upper side, the upper coupling portion 240, 260 is formed knuckle 200, and the sub-frame 300, the upper and lower coupling portions 320, 340 are formed on the side to correspond to the upper, lower coupling portions 240, 260 of the knuckle 200 And low links 420 and 440 interposed between the upper and lower coupling parts 240 and 260 of the knuckle 200 and the upper and lower coupling parts 320 and 340 of the subframe 300, and the knuckles. It consists of a rotating rod 500 coupled to the upper coupling portion 220 of the (20).

본 발명은 상기와 같이 구성되는 서스펜션의 토우장치(1)에 있어서, 상기 서브프레임(300)의 상, 하결합부(320, 340)에 각각의 전자석(600)이 장착되고 상기 로우링크(420, 440)의 길이방향으로는 코일(700)이 감기는 구성을 통해서 토우 변화량을 조절하는데 특징이 있다. According to the present invention, in the suspension tow device 1 configured as described above, the electromagnets 600 are mounted on the upper and lower coupling parts 320 and 340 of the subframe 300 and the low link 420 is provided. , 440 is characterized by adjusting the amount of tow change through the configuration in which the coil 700 is wound.

상기 서브프레임(300)의 상, 하결합부(320, 340)에 각각 장착되는 전자석(600)은 도체 주위에 전류가 흐를 때 자기장이 유도되어 전류가 흐르는 동안 강한 자성이 발생되어 도체를 자석으로 만들게 된다. 즉, 로우링크(420, 440)가 가변전자석이 되는 것이다. The electromagnet 600 mounted on the upper and lower coupling parts 320 and 340 of the subframe 300, respectively, induces a magnetic field when current flows around the conductor, and generates strong magnetism while the current flows. Will be made. That is, the low links 420 and 440 become variable electromagnets.

상기와 같이 형성된 로우링크(420, 440)는 서브프레임(300)의 상, 하결합부(320, 340)에 고정된 전자석(600)들의 극성에 따라 인력과 척력이 작용하게 되는 것이며 이때, 전류의 방향을 바꾸어 흘려 주면 N, S의 극도 바뀌게 되고 전류의 양에 따라 유도되는 자기장의 크기도 달라진다. The low links 420 and 440 formed as described above have the attraction force and the repulsive force depending on the polarities of the electromagnets 600 fixed to the upper and lower coupling parts 320 and 340 of the subframe 300. If you change the direction of, the poles of N and S will also change, and the magnitude of the induced magnetic field will change according to the amount of current.

상기 가변전자석이 된 로우링크(420, 440) 및 전자석(600)의 성질을 이용하여 서브프레임(300)에 있는 전자석(600)과 가변전자석이 된 로우링크(420, 440)를 차량 자세와 주행 상황에 따라 인력과 척력이 작용하면 링크 구조가 변화되어 토우 변화량을 가변시키게 되는 것이다. Vehicle posture and driving of the electromagnet 600 in the subframe 300 and the low link 420, 440 in the variable electromagnet using the properties of the low link 420, 440 in the variable electromagnet 600. If manpower and repulsive force act according to the situation, the link structure is changed to change the amount of tow change.

그리고 상기 서브프레임(300)의 전자석(600) 및 코일(700)이 감겨있는 로우링크(420, 440)에 공급되는 전류의 방향 및 양은 각종 센서들로부터 주행 상황에 대한 신호를 입력받아 연산하거나 맵핑된 정보에 따라 ECU에 결정하게 되는 것이다. The direction and amount of current supplied to the low links 420 and 440 on which the electromagnet 600 and the coil 700 of the subframe 300 are wound are calculated or mapped by receiving signals of driving conditions from various sensors. The information is then determined by the ECU.

도시된 도 3을 참조로 본 발명의 가변 토우시스템의 작동상태를 설명하면 다음과 같다. Referring to Figure 3 shown in the operating state of the variable tow system of the present invention.

상기 너클(200)의 상부결합부(240)와 상기 서브프레임(300)의 상부결합부(320)에 개재되는 로우링크(420)에 감겨있는 코일(700)의 A방향으로 전류를 흘려보내면 로우링크(420)의 좌측방향은 N극을 우측방향은 S극을 띄게 되며 이렇게 형성된 자장은 서브프레임(300)의 전자석(600)과 인력이 작용하여 로우링크(420)가 오른쪽으로 변위가 일어나게 된다. When the current flows in the A direction of the coil 700 wound on the low link 420 interposed between the upper coupling part 240 of the knuckle 200 and the upper coupling part 320 of the subframe 300, the low The left side of the link 420 has the N pole and the right side has the S pole. The magnetic field formed in this way causes the attraction of the electromagnet 600 of the subframe 300 to cause the low link 420 to be displaced to the right. .

또한, 너클(200)의 하부결합부(260)와 상기 서브프레임(300)의 하부결합부(340)에 개재되는 로우링크(440)에 감겨있는 코일(700)의 C방향으로 전류가 흘러가면 로우링크(440)는 왼쪽으로 변위가 일어나게 된다. In addition, when a current flows in the C direction of the coil 700 wound on the low link 440 interposed between the lower coupling part 260 of the knuckle 200 and the lower coupling part 340 of the subframe 300. The low link 440 is displaced to the left.

상기와 같은 방식으로 타이어는 토우인 특성을 나타내게 되고 반대로 전류를 코일(700)의 B, D방향으로 흘려주면 토우아웃의 특성을 나타내게 되는 것이다. In the same manner as described above, the tire exhibits toe-in characteristics, and on the contrary, when a current flows in the B and D directions of the coil 700, the tire exhibits toe-out characteristics.

또한, 흐르는 전류의 양에 따라 로우링크(420, 440)들의 변위가 달라지므로 토우특성을 차량자세와 주행 상황에 맞게 실시간으로 제어할 수 있게 되는 것이다. In addition, since the displacements of the low links 420 and 440 vary according to the amount of current flowing, the tow characteristic can be controlled in real time according to the vehicle posture and driving conditions.

본 발명에 따르면, 후륜의 토우 변화 특성을 차량 자세와 주행 상황에 맞게 실시간으로 정확하게 제어함으로써 차량의 성능을 높이고, 유압이나 그 밖의 제어시스템에 비해 비용이나 중량 측면에서 유리한 장점이 있다. According to the present invention, it is possible to increase the performance of the vehicle by accurately controlling the tow change characteristic of the rear wheel in real time according to the vehicle posture and driving conditions, and has advantages in terms of cost and weight over hydraulic or other control systems.
