본 발명은 더블 위시본형 프런트서스펜션에 관한 것으로, 특히 휠하우징패널과 휠하우징커버패널 및 어퍼암마운팅브라켓트의 결합강성을 증대시켜 전체적인 프런트서스펜션의 내구성과 조정안정성 및 NVH(Noise Vibration Harshness)성능을 향상시킴은 물론 아이들(idle)소음과 주행소음을 감소시킬 수 있도록 된 자동차의 프런트서스펜션구조에 관한 것이다.The present invention relates to a double wishbone type front suspension, and in particular, to increase the combined rigidity of the wheel housing panel, the wheel housing cover panel and the upper arm mounting bracket to improve the durability and adjustment stability of the overall front suspension and the noise vibration harness (NVH) performance. Sikkim, of course, relates to a front suspension structure of a vehicle that is capable of reducing idle noise and running noise.

일반적으로, 서스펜션(suspension)은 차축과 차체를 연결하여 주행할 때 노면에서 받는 진동이나 충격을 차체에 직접 전달되지 않도록 하여 차체나 하물의 손상을 방지하고 승차감을 좋게 하는 장치로서, 크게 프론트서스펜션과 리어서스펜션으로 분류된다.In general, a suspension is a device that prevents damage to a vehicle or a load and improves ride comfort by not transmitting vibrations or shocks received from the road surface directly when the vehicle is connected by connecting the axle and the vehicle body. It is classified as a suspension.

여기서, 상기 프런트서스펜션중 더블 위시본형 프런트서스펜션구조는 도 1과 도 2에 도시된 바와 같이, 좌우측 전륜(1)의 휠과 결합되는 너클(11)과, 상기 너클(11)의 상하단부에 볼조인트(도시않됨)를 매개로 각각 결합되면서 휠의 움직임을 조절하도록 된 어퍼암(12) 및 로어암(13)과, 양단이 상기 로어암(13)과 연결되도록 설치되어 차체가 옆으로 흔들리는 것을 방지하도록 된 스테빌라이저와, 노면에서 받는 충격을 완화하는 코일스프링(14a) 및 이 코일스프링(14a)의 자유진동을 억제하여 승차감을 좋게 하는 쇽업소버(14b)가 구비되면서 상기 로어암(14)의 상부에 종축방향으로 설치되도록 된 스트럿어셈블리(14)등으로 구성되어 있다.Here, the double wishbone front suspension structure of the front suspension, as shown in Figures 1 and 2, the knuckle 11 is coupled to the wheels of the left and right front wheels 1, and the upper and lower ends of the knuckle (11) The upper arm 12 and the lower arm 13 which are coupled to each other via a joint (not shown) to adjust the movement of the wheel, and both ends thereof are installed to be connected to the lower arm 13 to shake the vehicle body sideways. The lower arm 14 is provided with a stabilizer designed to prevent the shock, a coil spring 14a for mitigating an impact on the road surface, and a shock absorber 14b for suppressing free vibration of the coil spring 14a to improve ride comfort. Strut assembly 14, which is to be installed in the longitudinal axis of the upper portion is composed of.

또한, 상기 스트럿어셈블리(14)의 상부측에는 스트럿어셈블리(14)의 상단이 관통되는 휠하우징패널(15) 및 휠하우징커버패널(16)이 서로 중첩되어 설치되고,상기 휠하우징패널(15)과 휠하우징커버패널(16)의 일단은 각각 박스폐단면의 구조를 갖는 휀더에이프런어퍼멤버(17)와 접합되어 설치되며, 상기 휠하우징패널(15)의 타단은 프런트사이드멤버(23)와 접합되어 설치되는 구조로 되어 있다.In addition, the upper side of the strut assembly 14, the wheel housing panel 15 and the wheel housing cover panel 16 through which the upper end of the strut assembly 14 is installed to overlap each other, the wheel housing panel 15 and One end of the wheel housing cover panel 16 is installed to be bonded to the fender apron upper member 17 having a structure of a box closed end, respectively, and the other end of the wheel housing panel 15 is joined to the front side member 23. The structure is installed.

즉, 상기 휠하우징패널(15)의 안쪽 상부면에는 도 3과 도 4에 도시된 바와 같이 외주면을 따라 부분적으로 플랜지(16a)가 구비된 휠하우징커버패널(16)이 면접합되어 결합되고, 상기 휠하우징패널(15)의 안쪽 양측면에는 한쌍의 어퍼암마운팅브라켓트(18,19)가 각각 면접합되어 결합되는 구조로 되어 있다.That is, the wheel housing cover panel 16 having the flange 16a is partially bonded to the inner upper surface of the wheel housing panel 15 along the outer circumferential surface thereof, and is bonded to the inner upper surface of the wheel housing panel 15. A pair of upper arm mounting brackets 18 and 19 are bonded to each other on both inner side surfaces of the wheel housing panel 15.

여기서, 상기 휠하우징커버패널(16)과 한쌍의 어퍼암마운팅브라켓트(18,19)는 각각 휠하우징패널(15)하고만 용접결합될 뿐 서로 간에는 직접 연결되지 않는 구조로 되어 있다.Here, the wheel housing cover panel 16 and the pair of upper arm mounting brackets 18 and 19 are respectively welded only to the wheel housing panel 15 and are not directly connected to each other.

그리고, 상기 어퍼암마운팅브라켓트(18,19)의 내부공간으로는 어퍼암(12)의 양단이 각각의 부시(21,22)를 매개로 삽입되면서 휠하우징패널(15)과 볼트체결되어 결합되는 구조로 되어 있다.In addition, both ends of the upper arm 12 are inserted into each of the bushes 21 and 22 into the inner space of the upper arm mounting brackets 18 and 19 and bolted to the wheel housing panel 15. It is structured.

이와 같이 구성되는 프런트서스펜션은 자동차가 주행할 때 노면으로부터 전달되는 충격이나 상하진동을 억제하면서 차체가 좌우로 흔들리거나 비틀어지는 것을 방지하여 주행의 안정성을 향상시키고 탑승자의 승차감을 향상시키게 된다.The front suspension configured as described above prevents the vehicle body from swaying or twisting from side to side while suppressing the shock or vertical vibration transmitted from the road surface when the vehicle is running, thereby improving the stability of the driving and improving the riding comfort of the occupant.

그러나, 상기와 같은 종래의 프런트서스펜션구조에 의하면, 휠하우징커버패널(16)에 구비되는 플랜지(16a)가 스트럿어셈블리(14)가 관통되는 원형부의 외주면에만 형성되어 있음으로 인해 스트럿어셈블리(14)의 입력하중에 대해서는 충분한 강성을 지니게 되지만, 차체의 길이방향으로 입력되는 하중에 대해서는 이를 지탱할 수 있는 플랜지가 구비되어 있지 않아 전체적인 프런트서스펜션의 내구성을 약화시키는 문제점이 있었다.However, according to the conventional front suspension structure as described above, the strut assembly 14 because the flange (16a) provided in the wheel housing cover panel 16 is formed only on the outer peripheral surface of the circular portion through which the strut assembly 14 is penetrated. Although it has sufficient rigidity with respect to the input load of, there is a problem of weakening the durability of the overall front suspension because it is not provided with a flange to support the load input in the longitudinal direction of the vehicle body.

또한, 상기 휠하우징커버패널(16)과 한쌍의 어퍼암마운팅브라켓트(18,19)가 직접적으로 연결되어 있지 않고 휠하우징패널(15)을 통해 연결되는 구조로 되어 있어, 상기 휠하우징패널(15)과 휠하우징커버패널(16) 및 어퍼암마운팅브라켓트(18,19)의 조립체는 주행중 노면으로부터 스트럿어셈블리(14)를 통하여 입력되는 하중을 충분히 분산시키지 못하고 각각 잔류하중을 지니고 있게 되는데, 이와 같은 하중이 점차적으로 쌓이게 되면 전체적인 프런트서스펜션의 내구성을 약화되면서 아이들(idle)소음 및 주행소음이 심하게 발생되고 이로 인해 차량의 NVH(Noise Vibration Harshness)성능이 나빠짐은 물론 조정안정성도 나빠지게 되는 문제점도 있었다.In addition, the wheel housing cover panel 16 and the pair of upper arm mounting brackets 18 and 19 are not directly connected to each other and are connected through the wheel housing panel 15, so that the wheel housing panel 15 ) And the assembly of the wheel housing cover panel 16 and the upper arm mounting brackets 18 and 19 do not sufficiently distribute the load input through the strut assembly 14 from the road surface while driving, and have residual loads. As the load gradually builds up, the durability of the overall front suspension is weakened, and the idle noise and driving noise are severely generated. As a result, the vehicle's NVH (Noise Vibration Harshness) performance is deteriorated and the stability of adjustment is also deteriorated. .

이에 본 발명은 상기와 같은 모든 문제점들을 해소하기 위해 안출된 것으로, 휠하우징커버패널에 구비되는 플랜지를 전체의 외주면에 걸쳐 연장형성시키면서 상기 플랜지를 이용해 한쌍의 어퍼암마운팅브라켓트와 각각 결합시키고, 상기 어퍼암마운팅브라켓트의 하단부를 연장형성시켜 프런트사이드멤버에 결합시키며, 일체로 형성된 휠하우징패널을 서로 다른 두께를 갖는 어퍼하우징패널 및 로우하우징패널로 이원화시키면서 상기 로우하우징패널을 이용해 프런트사이드멤버와 결합시킴으로써, 전체적인 프런트서스펜션의 내구성을 강화시키면서 차량의 NVH(Noise Vibration Harshness)성능 및 조정안정성을 향상시키고 아울러 아이들(idle)소음및 주행소음을 감소시킬 수 있도록 된 자동차의 프런트서스펜션구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve all the problems described above, by coupling the pair of upper arm mounting brackets using the flange while forming the flange provided on the wheel housing cover panel over the entire outer circumferential surface, respectively, The lower portion of the upper arm mounting bracket is extended to be coupled to the front side member, and the wheel housing panel integrally formed with the upper housing panel and the lower housing panel having different thicknesses is combined with the front side member using the low housing panel. By providing the front suspension structure of the vehicle, it is possible to improve the vehicle's Noise Vibration Harshness (NVH) performance and control stability while reducing the overall noise of the front suspension and to reduce idle noise and running noise. There is this.

By the thickness of the upper housing panel (31a) it is possible to sufficiently maintain the rigidity of the overall wheel housing panel 31 it is possible to reduce the manufacturing cost of the wheel housing panel (31).

또한, 본 발명은 휠하우징커버패널(32)에 제1,2플랜지(32a,32b)를 형성시켜 휠하우징커버패널(32)이 가지는 자체적인 강성을 향상시키면서, 상기 플랜지(32b)를 이용해 어퍼암마운팅브라켓트(33,34)와 결합시키고, 아울러 상기 어퍼암마운팅브라켓트(33,34)를 프런트사이드멤버(23)에 결합시킴으로써, 전체적인 프런트서스펜션의 내구성을 강화시킬 수 있게 된다.In addition, the present invention forms the first and second flanges (32a, 32b) on the wheel housing cover panel 32 to improve the rigidity of the wheel housing cover panel 32, while using the upper flange (32b) By combining with the arm mounting bracket (33,34), and by combining the upper arm mounting bracket (33,34) to the front side member 23, it is possible to enhance the durability of the overall front suspension.

이러한 결합구조에 의해 전체적인 프런트서스펜션의 내구성이 종래의 구조보다 증대되면, 차량의 NVH(Noise Vibration Harshness)성능과 주행중 차량의 조정안정성이 그만큼 향상되게 되고, 아울러 아이들(idle)소음 및 주행소음도 대폭적으로 감소시킬 수 있게 된다.When the durability of the overall front suspension is increased by such a coupling structure than the conventional structure, the performance of the vehicle's NVH (Noise Vibration Harshness) and the stability of the vehicle's adjustment while driving are greatly improved, and the idle noise and the running noise are also greatly increased. Can be reduced.

이상 설명한 바와 같이 본 발명에 의하면, 휠하우징패널과 휠하우징커버패널 및 어퍼암마운팅브라켓트의 결합강성이 증대됨으로써 전체적인 프런트서스펜션의내구성이 강화되고, 이로 인해 차량의 NVH(Noise Vibration Harshness)성능과 조정안정성이 그만큼 향상되게 되며, 아울러 아이들(idle)소음 및 주행소음도 대폭적으로 감소되는 효과가 있게 된다.As described above, according to the present invention, by increasing the coupling rigidity of the wheel housing panel, the wheel housing cover panel and the upper arm mounting bracket, the durability of the overall front suspension is strengthened, and thus the vehicle's NVH (Noise Vibration Harshness) performance and adjustment Stability is improved by that, and the idle noise and running noise are also greatly reduced.
