Description

차량의 전륜 현가장치Vehicle front wheel suspension

본 고안은 차량의 전륜 현가장치에 관한 것으로, 더욱 상세하게는 로워아암의 프론트 아암 장착 포인트를 차량 앞쪽으로 배치한 변형 맥퍼슨 타입에서 서브 프레임에 마운팅되는 프론트 아암 일단에 보조링크를 연결 설치하여 토인을 억제하기 위한 차량의 전륜 현가장치에 관한 것이다.The present invention relates to a front wheel suspension of a vehicle. More specifically, in a modified McPherson type in which the front arm mounting point of the lower arm is disposed toward the front of the vehicle, the auxiliary link is connected to one end of the front arm that is mounted on the subframe. A front wheel suspension of a vehicle for suppressing.

자동차에 있어서의 현가장치는 차체와 차륜사이에 존재하면서 이 2개의 강체를 하나 혹은 다수의 컨트롤 아암으로 연결하여 상하방향으로는 스프링과 쇽 업소오버에 의하여 지지되고, 기타 방향으로 높은 강성과 유연성을 적절히 조화시킴으로써, 차체와 차륜사이의 상대운동을 기계적으로 적절히 조화시켜 주행중 노면으로부터 받는 진동과 충격을 흡수하여 승차감과 선회 안정성을 향상시키는 장치이다.Suspensions in automobiles exist between the body and the wheels and are connected by one or more control arms, supported by springs and shock absorbers in the vertical direction, and high rigidity and flexibility in the other directions. By appropriately harmonizing, the relative motion between the vehicle body and the wheels is mechanically harmonized to absorb vibrations and shocks received from the road surface while driving, thereby improving ride comfort and turning stability.

이러한 현가장치는 노면으로부터의 입력에 대한 여러 부문의 성능을 만족시키기 위하여 다음의 3가지 조건이 요구되고 있다.In order to satisfy the performance of various sectors for the input from the road surface, the following three conditions are required.

첫째, 조정 안정성을 위하여 타이어는 노면에 대하여 이상적인 자세를 유지케 하여 노면에 대한 그립(grip)력을 극대화하고, 차체는 나름대로 최상의 자세를 유지하여 목적하는 차량 운동상태를 가능케 하여야 하며, 특히 어떠한 상태에서도 항상 다음 동작을 얻을 수 있는 순간력을 지님과 동시에 운전자의 의도하는 방향 및 순간 외에는 외부 입력에 의한 어떠한 거동도 허용하면 안된다.First, for the stability of adjustment, the tire should maintain the ideal posture on the road surface to maximize the grip force on the road, and the body should maintain the best posture in its own way to enable the desired vehicle movement state. In addition, it must not have any momentary force to get the next motion at all times and at the same time allow any action by external input except the driver's intended direction and moment.

둘째, 안락감을 위하여 어떠한 충격도 민첩하게 흡수할 수 있도록 하여 차내에 있는 탑승자들로 하여금 불쾌감을 느끼지 못하도록 하여야 한다.Secondly, for comfort, it should be possible to absorb any shock quickly so that passengers in the car may not feel uncomfortable.

셋째, 충돌시 이의 충돌에너지의 흡수에 기여토록 하여 충돌 안정성을 증대시킬 수 있도록 하여야 한다.Third, the collision stability should be contributed to the absorption of the collision energy of the collision.

상기와 같은 현가장치의 요구조건에 있어서, 이제까지는 첫째와 둘째 조건을 충족시키기 위한 개발이 중점적으로 이루어지고 이에 설계된 현가장치가 양산차량에 적용되고 있으나, 최근에는 안전도에 대한 규제가 점차적으로 까다로워짐으로써, 기존 현가장치의 설계 개념만으로는 이를 충족시키기에는 역부족이었다.In the above requirements of the suspension system, until now, development to meet the first and second conditions has been intensively and the suspension system designed for this has been applied to mass production vehicles, but in recent years, the safety regulations have become increasingly difficult. As a result, the design concept of the existing suspension system was not sufficient to satisfy this.

이에 따라 최근에는 차체 구조에 악영향을 미치지 않는 조건에서 전면 및 오프셋 충돌시 이의 충돌 에너지를 효과적으로 흡수하여 충돌 안정성을 향상시킬 수 있는 현가장치가 초보단계로서 개발되고 있는 실정이다.Accordingly, in recent years, a suspension system that can effectively absorb collision energy in front and offset collisions and improve collision stability under conditions that do not adversely affect the vehicle body structure has been developed as an initial stage.

이러한 점을 고려하여 전륜에 적용되고 있는 종래의 로워아암에서 프론트 아암의 장착 포인트를 차량 전방측으로 배치한 변형 맥퍼슨 타입을 도3에 의하여 설명하면 로워아암(2)의 프론트 아암(4)을 서브 프레임(6)의 일측에 형성한 브라켓트(8)에 너트(10)로 체결하여 이루어지고 있다.In view of the above, the modified McPherson type in which a mounting point of the front arm is disposed toward the front side of the vehicle in the conventional lower arm applied to the front wheel will be described with reference to FIG. 3. The front arm 4 of the lower arm 2 is subframed. It is made by fastening with the nut 10 to the bracket 8 formed in one side of (6).

상기한 브라켓트(8)의 양측에는 지지판(12)을 설치하고, 이 사이에 고무부시(14)를 개재하여 외력을 흡수하게 하고 있다.Support plates 12 are provided on both sides of the bracket 8, and the external force is absorbed through the rubber bush 14 therebetween.

상기한 전륜 현가장치는 제동시 차륜(T)을 통해 외력을 전달받게 되어 접지점이 P점에서 P'점으로 이동한다.The front wheel suspension receives external force through the wheel (T) during braking to move the ground point from P point to P 'point.

따라서 로워아암(2)은 고무부시(14)의 변형과 부시(16)의 변형에 의해 a점에서 b점으로 이동한다.Therefore, the lower arm 2 moves from point a to point b by the deformation of the rubber bush 14 and the deformation of the bush 16.

이때 타이로드(18)로 후축이 연결되고 있는 차륜(T)은 c점에서 d점으로 변위가 이루어져 급격한 토-인 상태가 된다.At this time, the wheel (T) that is connected to the rear shaft to the tie rod 18 is a displacement from the c point to the d point is a sudden toe-in state.

이러한 전륜 현가장치는 부시의 횡강성 부족 및 전,후력 작용시 과도한 토-인이 발생하여 차체의 안정성을 저해하는 문제점이 있다.Such a front wheel suspension has a problem of inhibiting the stability of the vehicle body due to the lack of lateral stiffness of the bush and excessive toe-in during the front and rear action.

상기한 바와 같이 이루어지는 종래기술의 문제점을 해소하기 위하여 안출한 본 고안의 목적은 로워아암의 프론트 아암 장착 포인트를 차량 앞쪽으로 배치한 변형 맥퍼슨 타입에서 서브 프레임에 마운팅되는 프론트 아암 일단에 보조링크를 연결 설치하여 토인을 억제하기 위한 차량의 전륜 현가장치를 제공하는데 있다.The object of the present invention devised to solve the problems of the prior art made as described above is to connect the auxiliary link to one end of the front arm mounted on the subframe in the modified McPherson type in which the front arm mounting point of the lower arm is disposed toward the front of the vehicle. The present invention provides a front wheel suspension of a vehicle for suppressing toe by installing.

이하, 본 고안의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

도1은 본 고안에 따른 전륜 현가장치를 도시한 도면이고, 도2는 도1의 A를 확대 도시한 도면으로, 서브 프레임(20)의 브라켓트(22)에 고무부시(24)를 개재하면서 연결 설치되는 로워아암(26)의 프론트 아암(28)에 일측 끝단에 보조링크(30)를 너트(32)로 연결하고 있다.1 is a diagram illustrating a front wheel suspension according to the present invention, and FIG. 2 is an enlarged view of FIG. 1A and is connected to a bracket 22 of a subframe 20 with a rubber bush 24 interposed therebetween. The auxiliary link 30 is connected to the front arm 28 of the lower arm 26 to be installed at one end by a nut 32.

상기한 보조링크(30)의 타단에는 부시(34)를 형성하고 있으며, 이 부시(34)를 관통하는 지지링크(36)를 너트(32)로 연결하고 있다.A bush 34 is formed at the other end of the auxiliary link 30, and the support link 36 penetrating the bush 34 is connected by a nut 32.

그리고 지지링크(36)의 다른 끝단은 서브 프레임(20)에 장착된 보조 브라켓트(38)에 연결 설치하고 있다.The other end of the support link 36 is connected to the auxiliary bracket 38 mounted on the subframe 20.

상기한 바와 같이 이루어지는 본 고안의 작용을 도2에 의하여 설명하면 차륜에 횡강성 작용과 전,후력 작용시 고무부시(24)로 지지되고 있는 프론트 아암(28)은 b점이 b'점으로 이동하면서 로워아암(26)의 a점은 a'점으로 이동한다.Referring to FIG. 2, the front arm 28, which is supported by the rubber bush 24 during the lateral stiffness and the front and rear forces, moves the b point to the b 'point. Point a of the lower arm 26 moves to point a '.

이때 타이로드(40)가 c점에서 c'점으로 이동할 때 부시(24)의 변형도 함께 이루어진다.At this time, when the tie rod 40 moves from point c to point c ', deformation of the bush 24 is also made.

따라서 지지링크(36)로 지지되는 보조링크(30)에 의해 로워아암(26)의 프론트 아암(28)을 지지하므로서 로워아암(26)의 a점에서 a'점으로의 변위량을 최소로 억제하여 과도하게 토-인 상태로 변화하는 것을 차단한다.Accordingly, by supporting the front arm 28 of the lower arm 26 by the auxiliary link 30 supported by the support link 36, the amount of displacement from the point a to the point a 'of the lower arm 26 is minimized. Prevents excessive toe-in transitions.

본 고안은 로워아암의 프론트 아암에 지지링크로 연결되는 보조링크를 설치하므로서 로워아암의 변위폭을 억제하여 횡강성을 증대하게 된다.The present invention increases the lateral stiffness by suppressing the displacement width of the lower arm by providing an auxiliary link connected to the support link on the front arm of the lower arm.

이로서 제동시 과도한 토-인 상태로 변화되는 것을 억제하여 주행 안정성을 도모하게 되는 고안이다.As a result, it is designed to suppress the change in the excessive toe-in state during braking and promote driving stability.
