본 발명은 차량용 SLA 위시본식 현가장치에 관한 것이며, 상세하게는 차량용 SLA(short/long arm) 위시본식 현가장치에 있어서 차량의 선회시의 부(-)의 캠버값과 휠 트레드의 증대구조에 관한 것이다.BACKGROUND OF THE
현가장치는 차축과 프레임을 연결하여 주행중 노면에서 받은 진동이나 충격을 흡수하여 승차감과 안전성을 향상시키는 장치이며, 상기 현가장치는 상ㆍ하방향 이 유연하여 노면에서 받는 충격을 양호하게 완화하고, 수평방향의 연결이 견고하여 바퀴에 생기는 구동력, 제동력 선회시의 원심력을 이겨내야 한다.Suspension system is a device that connects the axle and the frame to absorb vibrations or shocks received from the road surface while driving to improve riding comfort and safety. The connection in the direction is strong so that the driving force and braking force generated on the wheel must be overcome.
현가장치는 일체식 차축 현가장치와, 독립현가장치로 대별되며, 독립현가장치는 스프링 아래 질량이 크기 때문에 승차감이 좋고, 바퀴에 옆방향으로 요동하는 진동(shimmy)이 잘 일어나지 않고, 타이어와 노면의 접지성(接地性, road holding)이 우수하며, 스프링 상수가 작은 스프링을 사용할 수 있는 장점을 가지고 있는 반면에, 연결부분이 많아 구조가 복잡하게 되고, 이들의 마모에 의하여 휠 얼라인먼트(wheel alignment)가 변하기 쉬우며, 주행시 바퀴가 상하로 움직임으로 휠 트레드와 휠 얼라인먼트가 변하기 쉽기 때문에 타이어가 쉽게 마모되는 단점도 있으나 승차감이나 조종성을 중요시하는 승용차에 많이 사용하고 있다.Suspensions are classified into integrated axle suspensions and independent suspensions.Independent suspensions have a high mass under the spring, which provides a comfortable ride. It has excellent road holding and has the advantage of using a spring with a small spring constant, while the connection part is complicated and the structure becomes complicated, and the wheel alignment is caused by their wear. It is easy to change, and the wheel tread and wheel alignment change easily when driving, so the tires are easily worn, but it is used in passenger cars that emphasizes riding comfort or maneuverability.
한편 차량이 선회할 때 일측 바퀴는 리바운드(rebound)를, 타측 바퀴는 범프(bump)를 하게 됨으로 현가장치 설계자들은 안정된 선회(코너링, cornering)을 하기 위하여서 범프를 하는 바퀴는 부(-)의 캠버각을 가지도록 하여 휠 트레드를 증가시킴으로써 선회력을 증가할 수 있게 설계하고 있다.On the other hand, when the vehicle turns, one wheel rebounds and the other wheels bump, so the suspension designers use a negative camber to bump the wheels for stable turning. It is designed to increase turning force by increasing wheel tread with angle.
상기 독립현가장치 중 위시본식 현가장치는 평행사변형과 SLA형(short/long arm type)으로 대별되며, 평행사변형은 캠버값은 변화가 없음으로 커브 주행중에 안전성이 요구되는 경주용 자동차에 국한 사용되고, SLA형은 캠버값과 휠 트레드가 변화함으로 선회성능이 향상됨으로써 일반 승용차에 주로 사용하고 있다.Wishbone suspension system of the independent suspension device is roughly divided into parallelogram and SLA (short / long arm type), the parallelogram is used only in a racing car that requires safety while driving the curve because the camber value does not change, SLA type is mainly used in general passenger cars by improving turning performance by changing camber value and wheel tread.
상기 SLA형 현가장치는 하방부에 스핀들이 설치되는 너클과; 상기 너클의 상ㆍ하단에 일단을 볼 조인트로 결합하고 상부 암이 하부 암보다 그 길이가 짧은 상 ㆍ하 콘트롤 암과; 상기 상ㆍ하 콘트롤 암 사이에 설치하는 쇽업쇼바로 구성한 것이다.The SLA-type suspension includes a knuckle having a spindle installed below; An upper and lower control arm coupled at one end to a ball joint at the upper and lower ends of the knuckle, and having an upper arm shorter in length than a lower arm; The shock absorber is disposed between the upper and lower control arms.
상기한 SLA형 현가장치에 있어서, 설계자들이 채용할 수 있는 설계변수는 너클의 형상, 상ㆍ하 콘트롤 암의 길이 또는 그 경사의 기하학적 배치에 의하여 캠버, 토우, 캐스터 등의 차륜정렬요소를 정하고 있는바, 상기와 같은 설계변수는 단순하고, 또한 상기 차륜정렬요소 중 캠버값과 휠 트레드는 고정값을 가짐으로 통상의 선회상황에서는 안정된 선회를 할 수 있는 부의 캠버값과 휠 트레드의 증대를 달성할 수 있으나, 도로상황, 적재중량 등을 감안한 모든 선회상황조건에서 항상 만족할 수 있는 캠버값과 휠 트레드 증대를 이룩할 수 없게 되어 이경우 선회력이 감소되기 때문에 항상 양호한 선회안정성의 실현이 곤란한 문제점이 있는 것이다.In the above-described SLA type suspension system, the design variables that designers can adopt are the wheel alignment elements such as camber, toe, caster, etc. determined by the shape of the knuckle, the length of the upper and lower control arms, or the geometric arrangement of the inclination thereof. The above design parameters are simple, and the camber value and wheel tread of the wheel alignment elements have a fixed value, so that the negative camber value and wheel tread can be increased to enable stable turning in a normal turning situation. However, it is difficult to achieve the camber value and wheel tread increase that can always be satisfied in all turning conditions considering the road situation, loading weight, etc. In this case, the turning force is reduced, so it is difficult to realize good turning stability at all times.
본 발명은 상기한 문제점을 시정하여, 모든 선회상황조건에서 선회안전성을 유지할 수 있는 차량용 SLA 위시본식 현가장치를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention aims to provide a vehicle SLA wish suspension system for correcting the above problems, which can maintain turning safety in all turning conditions.

상기 액츄에이터(23)는 유압실린더로 구성하여 상기 쇽업쇼바(14)에 도관(24)으로 연결하여 범프시 쇽업쇼바(14)가 수축될 때 그 유압을 공급받거나, 브라켓(22a)(22b) 중의 어느 하나에 모터를 설치하고 상기 모터와 액츄에이터(23)의 일단에 랙피니온기구 또는 나사연결기구 등을 설치하여 조향각 센서의 출력신호를 제어기에 입력하여 제어기의 출력전류에 의하여 모터를 회전하여 범프시에 액츄에이터(23)를 신장시킬 수 있다.The
이상과 같은 본 발명은 선회시에 기존의 방법에 의하여 부의 캠버값과 휠 트레드를 증가함과 동시에 액츄에이터(23)를 신장시켜 제 1 너클(20a)은 반시계방향으로 제 2 너클(20b)은 시계방향으로 회전시킴으로써 도로상황, 적재중량 등을 감 안한 모든 선회상황에서 부의 캠버값과 휠 트레드를 양호하게 증가(변화)시킬 수 있는 것이다.As described above, the present invention increases the negative camber value and the wheel tread by the conventional method during turning, and simultaneously extends the

By installing an actuator, it is possible to increase negative camber value and wheel tread in all turning situations of the vehicle, thereby increasing turning power and turning adhesive force between the tire and the road surface while maintaining turning stability. To reduce wear.
