Description
본 발명은 자동차용 리어 서스펜션부의 고정구조에 관한 것으로서, 보다 상세하게는 리어 서스펜션이 2중으로 지지되도록 그 고정구조를 개선함으로써 차체의 비틀림을 방지하고 코너링 후에도 차체가 안정되도록 하며 리어 서스펜션으로부터 전달되는 진동을 최대한 억제시킨 자동차용 리어 서스펜션부의 고정구조에 관한 것이다.The present invention relates to a fixed structure of a vehicle rear suspension portion, and more particularly, by improving the fixing structure so that the rear suspension is double supported, to prevent the torsion of the vehicle body, to stabilize the vehicle body even after cornering and vibration transmitted from the rear suspension. It relates to a fixed structure of the rear suspension unit for cars to suppress the maximum.
일반적으로 자동차에 적용되는 서스펜션(Suspension: 현가장치)은 차축과 프레임을 연결하고, 주행 중 노면으로부터 받는 진동과 충격을 흡수하여 자동차의 승차감과 안정성을 향상시키는 장치이다.Suspensions (suspensions), which are generally applied to automobiles, are devices that connect the axles and the frame and absorb vibrations and shocks received from the road surface while driving to improve ride comfort and stability of the vehicle.
서스펜션은 크게 쇽업쇼버 파트와 스프링 파트로 구성되는데, 쇽업쇼버(Shock absorber)는 노면으로부터의 충격을 완화하기 위하여 상하 방향의 연결이 유연하여야 하고, 휠에 발생되는 구동력, 제동력, 선회시의 원심력 등을 극복할 수 있는 수평 방향의 연결이 견고하여야 한다.The suspension consists of a shock absorber part and a spring part. The shock absorber must be flexible in the vertical direction to alleviate the impact from the road surface, and the driving force, the braking force, and the centrifugal force during the turning The horizontal connection should be robust to overcome this problem.
이러한 쇽업쇼버는 그 구조적인 특성에 따라 여러 종류로 구분되어지며, 가장 이상적인 기하학적 특성을 갖는 쇽업쇼버가 차량에 선별적으로 적용되고 있는 바, 승용차의 경우에는 통상적으로 프론트샤프트에 차축을 분할하여 두 개의 휠이 서로 독립적으로 동작하게 되어 승차감과 안전성이 좋은 독립 현가방식이 적용된다.These shock absorbers are classified into various types according to their structural characteristics. A shock absorber having the most ideal geometric characteristics is selectively applied to a vehicle. In the case of a passenger car, the axle is generally divided into two parts on the front shaft. The two wheels operate independently of each other, and the independent suspension system with good ride comfort and safety is applied.
또한, 프론트샤프트와는 별도로 리어휠이 장착되는 리어샤프트에는 차체의 뒷부분을 지지하는 리어 서스펜션 방식이 적용된다. 이하, 리어 서스펜션 방식에 대하여 설명하기로 한다.In addition, a rear suspension system for supporting the rear portion of the vehicle body is applied to the rear shaft in which the rear wheel is mounted separately from the front shaft. Hereinafter, the rear suspension system will be described.
도1은 일반적인 리어 서스펜션부를 보인 도면이고, 도2는 종래 리어 서스펜션부를 고정하는 쿼터인너패널과 휠하우징패널 및 쇽업쇼버커버를 보인 분해 사시도이며, 도3은 종래 리어 서스펜션부의 고정구조를 보인 단면도이다.1 is a view showing a general rear suspension portion, Figure 2 is an exploded perspective view showing a quarter inner panel, a wheel housing panel and a shock absorber cover for fixing the conventional rear suspension portion, Figure 3 is a cross-sectional view showing a fixed structure of the conventional rear suspension portion. .
도1에 도시된 바와 같이, 리어 서스펜션(10)은, 브레이크 드럼(미도시)에 고정 장착된 너클(11)에 리어 쇽업쇼버(12)가 고정되어 차체 브래킷(1)의 하단을 지지하고, 이 리어 쇽업쇼버(12)가 장착되는 너클(11)의 하측에는 리어 서스펜션 아암(13)이 차폭 방향으로 제공되는 센터 멤버(미도시)의 일측에 상하로 회전 가능하게 장착되어 리어휠(14)을 지지하도록 구성된다.As shown in FIG. 1, the rear suspension 10 has a rear shock absorber 12 fixed to a knuckle 11 fixed to a brake drum (not shown) to support the lower end of the vehicle body bracket 1, On the lower side of the knuckle 11 to which the rear shock absorber 12 is mounted, a rear suspension arm 13 is rotatably mounted up and down on one side of a center member (not shown) provided in the vehicle width direction, and the rear wheel 14 It is configured to support.
종래 리어 서스펜션부의 고정구조는 도2 및 도3에 도시된 바와 같이, 리어플로워패널(20)과 쿼터인너패널(21a) 사이에 휠하우징패널(22)이 위치되어 상기 리어플로워패널(20)의 일단과 휠하우징패널(22)이 결합되고, 상기 휠하우징패널(22)의 결합홈(22a)에는 쇽업쇼버커버(23)가 끼워 결합된다.As shown in FIG. 2 and FIG. 3, the wheel housing panel 22 is positioned between the rear follower panel 20 and the quarter inner panel 21a, so that the rear structure of the rear follower 20 is fixed. One end and the wheel housing panel 22 are coupled to each other, and the shock absorber cover 23 is fitted to the coupling groove 22a of the wheel housing panel 22.
여기서, 리어 서스펜션(10)의 일측단은 쇽업쇼버커버(23)의 결합공(23a)에 끼워져 관통된 상태로 볼트 체결됨으로써 고정 설치된다.Here, one side end of the rear suspension 10 is fixedly installed by being bolted in a penetrating state through the coupling hole 23a of the shock absorber cover 23.
한편, 상기 쇽업쇼버커버(23)는 상기 쿼터인너패널(21a)의 일측과 결합되고, 상기 쿼터인너패널(21a)은 쿼터아웃터패널(21b)과 다시 결합되어 폐단면을 이루게 됨으로써 쇽업쇼버커버(23)의 결합강도를 높이게 된다.On the other hand, the shock absorber cover 23 is coupled to one side of the quarter inner panel 21a, and the quarter inner panel 21a is combined with the quarter outer panel 21b again to form a closed cross section so as to form a shock absorber cover ( 23) increase the bonding strength.
따라서, 상기 리어 서스펜션(10)을 통해 입력되는 충격하중은 쇽업쇼버커버(23)에서 휠하우징패널(22)을 거쳐 리어플로워패널(20)측으로도 전달되고, 상기 쿼터인너패널(21a)을 거쳐 상기 쿼터아웃터패널(21b)측으로도 전달되어 충돌에너지를 분산시키게 된다.Accordingly, the impact load input through the rear suspension 10 is also transmitted from the shock absorber cover 23 to the rear follower panel 20 through the wheel housing panel 22 and through the quarter inner panel 21a. It is also delivered to the quarter outer panel 21b to disperse the collision energy.
그러나, 이와 같이 구성된 종래의 자동차용 리어 서스펜션 고정구조에서는, 리어 서스펜션(10)이 쇽업쇼버커버(23)를 매개로 1점 지지되어 리어플로워패널(20) 및 쿼터인너패널(21a)과 연결되므로 상기 리어 서스펜션(10)을 통해 큰 충격하중이 입력되면 쇽업쇼버커버(23)가 매우 크게 진동되어, 그로 인한 차체 비틀림이 증가하며 자동차의 내구력과 승차감이 떨어지고 진동 노이즈가 발생하는 문제점이 있다.However, in the conventional vehicle rear suspension fixing structure configured as described above, since the rear suspension 10 is supported by one point through the shock absorber cover 23 and connected to the rear follower panel 20 and the quarter inner panel 21a, When a large impact load is input through the rear suspension 10, the shock absorber cover 23 is vibrated very much, resulting in increased body torsion, resulting in a decrease in durability and ride comfort of the vehicle and vibration noise.
또한, 종래 자동차용 리어 서스펜션 고정구조에서는, 리어 서스펜션(10)에서 전달되는 힘이 쇽업쇼버커버(23)와 휠하우징(22)을 따라 리어플로워패널(20) 및 쿼터인너패널(21a)로 이동되어 그 결합부위에 응력집중이 생기므로 리어플로워패널(20)과 쿼터인너패널(21a)의 결합면에 크랙이 발생되는 문제점이 발생된다.In addition, in the conventional vehicle rear suspension fixing structure, the force transmitted from the rear suspension 10 moves along the shock absorber cover 23 and the wheel housing 22 to the rear follower panel 20 and the quarter inner panel 21a. As a result of stress concentration at the coupling portion, cracks are generated at the coupling surface of the rear follower panel 20 and the quarter inner panel 21a.
본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 차량후방의 리어플로워패널과 쿼터인너패널 사이에 고정설치되는 리어 서스펜션의 고정구조를 개선하여 리어 서스펜션의 지지력 및 결합강도를 높임으로써 차체 비틀림과 진동노이즈를 억제하고 승차감을 향상시키는데 있다.The present invention has been proposed to solve the above problems, the object of which is to improve the fixing structure of the rear suspension fixed between the rear floor panel and the quarter inner panel of the rear of the vehicle to improve the bearing capacity and coupling strength of the rear suspension Increasing to suppress body torsion and vibration noise and improve ride comfort.
또한, 리어 서스펜션의 지지력 및 결합강도를 높임으로써 리어플로워패널 및 쿼터인너패널의 결합부위에 크랙이 발생되는 종래의 문제점을 해소하는데 있다.In addition, by improving the bearing capacity and the coupling strength of the rear suspension to solve the conventional problem that the crack is generated in the coupling portion of the rear floor panel and the quarter inner panel.
상기의 목적을 달성하기 위한 본 발명은, 차량후방의 리어플로워패널과 쿼터인너패널 사이의 공간에 리어 서스펜션이 고정 결합되고, 상기 쿼터인너패널은 쿼터아웃터패널과 결합되어 폐단면이 형성되는 자동차용 리어 서스펜션부의 고정구조에 있어서, 상기 리어플로워패널의 일측단과 상기 쿼터인너패널의 일측 사이에는 휠하우징패널이 결합되고, 상기 휠하우징패널의 하부에는 그 휠하우징패널의 일측과 쿼터인너패널의 타측을 연결하는 휠하우징보강패널이 결합되며, 상기 리어 서스펜션의 일측 끝단부는 상기 휠하우징패널과 휠하우징보강패널을 관통하여 2점 지지되도록 고정 설치된 자동차용 리어 서스펜션부의 고정구조이다.The present invention for achieving the above object, the rear suspension is fixedly coupled to the space between the rear floor panel and the quarter inner panel in the rear of the vehicle, the quarter inner panel is coupled to the quarter outer panel for automobiles are closed In the fixed structure of the rear suspension portion, a wheel housing panel is coupled between one side end of the rear follower panel and one side of the quarter inner panel, and one side of the wheel housing panel and the other side of the quarter inner panel is disposed below the wheel housing panel. The wheel housing reinforcement panel is coupled to each other, and one end of the rear suspension is fixed to the rear suspension unit for the vehicle, which is fixed to be supported by two points through the wheel housing panel and the wheel housing reinforcement panel.
이하, 본 발명의 구성을 첨부된 도면에 의거하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on attached drawing.
도4는 리어 서스펜션부를 고정하는 본 발명의 쿼터인너패널과 휠하우징패널 및 휠하우징보강패널을 보인 분해 사시도이며, 도5는 본 발명의 리어 서스펜션부 고정구조를 보인 단면도이다.Figure 4 is an exploded perspective view showing a quarter inner panel, a wheel housing panel and a wheel housing reinforcement panel of the present invention for fixing the rear suspension portion, Figure 5 is a cross-sectional view showing a rear suspension portion fixing structure of the present invention.
도4 및 도5에서 살펴보면, 차량의 후방에는 차체 바닥면을 이루는 리어플로워패널(30)이 마련되고, 자동차의 뒷바퀴(w) 상부에는 차체의 쿼터부(31)를 이루는 쿼터인너패널(31a)과 쿼터아웃터패널(31b)이 서로 결합되어 있다.4 and 5, the rear follower panel 30 forming the bottom surface of the vehicle is provided at the rear of the vehicle, and the quarter inner panel 31a forming the quarter portion 31 of the vehicle body is disposed on the rear wheel w of the vehicle. And the quarter outer panel 31b are coupled to each other.
차량의 뒷바퀴(w)에서 전달되는 충격은 뒷바퀴(w)와 연결된 리어 서스펜션(10)에서 흡수하여 감쇄되는데, 상기 리어 서스펜션(10)은 상기 리어플로워패널(30)과 쿼터인너패널(31a) 사이의 공간에 고정 결합되어야 한다.The shock transmitted from the rear wheel (w) of the vehicle is absorbed and attenuated by the rear suspension (10) connected to the rear wheel (w), the rear suspension 10 is between the rear follower panel 30 and the quarter inner panel (31a) It must be fixed in space.
이에 따른 본 발명의 리어 서스펜션부 고정구조는 도5에 보다 명확하게 나타나 있는데, 여기서 보면 상기 리어플로워패널(30)의 일측단에 휠하우징패널(32)의 일단이 고정결합되고, 상기 휠하우징패널(32)은 상향으로 연장되면서 절곡되어 그 타단이 상기 쿼터인너패널(31a)의 일측에 고정결합된다.Accordingly, the rear suspension fixing structure of the present invention is shown more clearly in FIG. 5, where one end of the wheel housing panel 32 is fixedly coupled to one side end of the rear follower panel 30, and the wheel housing panel is fixed. 32 is bent while extending upward, the other end is fixedly coupled to one side of the quarter inner panel 31a.
또한, 상기 휠하우징패널(32)의 하부에는 그 휠하우징패널(32)의 내면 일측과 쿼터인너패널(31a)의 타측을 상호 연결하는 휠하우징보강패널(33)이 결합되는데, 상기 휠하우징보강패널(33)은 리어 서스펜션(10)이 고정되는 상기 휠하우징패널(32)의 강도를 보강하기 위하여 별도로 휠하우징패널(32)의 하부에 설치됨으로써 휠하우징패널(32)과의 사이에서 또 다른 밀폐공간을 형성하게 된다.In addition, a wheel housing reinforcement panel 33 is connected to a lower portion of the wheel housing panel 32 to interconnect one side of the inner surface of the wheel housing panel 32 and the other side of the quarter inner panel 31a. The panel 33 is separately installed under the wheel housing panel 32 to reinforce the strength of the wheel housing panel 32 to which the rear suspension 10 is fixed, so that the panel 33 is further separated from the wheel housing panel 32. It creates a sealed space.
이렇게 상, 하 2중으로 휠하우징패널(32) 및 휠하우징보강패널(33)이 설치된 곳에 상기 리어 서스펜션(10)의 일측 끝단부가 상기 휠하우징패널(32)과 휠하우징보강패널(33)을 관통하여 2점 지지되도록 고정 설치된다. 이때 상기 리어 서스펜션(10)이 볼트 체결을 통해 고정되는 것은 공지의 사실이므로 본 발명에서는 볼트 체결에 대한 구체적인 설명 및 도면에서의 표현은 생략하고 리어 서스펜션부의 고정구조에 대해서만 설명하기로 한다.One end of the rear suspension 10 penetrates the wheel housing panel 32 and the wheel housing reinforcement panel 33 where the wheel housing panel 32 and the wheel housing reinforcement panel 33 are installed. 2 points are fixedly installed. In this case, since the rear suspension 10 is fixed through bolt fastening, it is well known. In the present invention, the detailed description of the bolt fastening and the expression in the drawings will be omitted and only the fixing structure of the rear suspension part will be described.
한편, 리어 서스펜션(10)이 고정설치되는 상기 휠하우징패널(32)과 휠하우징보강패널(33) 사이에는 상기 리어 서스펜션(10)의 일측 끝단부를 감싸면서 지지하는 쇽업쇼버파이프(34)가 설치된다.Meanwhile, a shock absorber pipe 34 is provided between the wheel housing panel 32 and the wheel housing reinforcement panel 33 on which the rear suspension 10 is fixed, while wrapping and supporting one end of the rear suspension 10. do.
상기 쇽업쇼버파이프(34)는 속인 빈 중공의 파이프로서, 상기 리어 서스펜션(10)의 일측 끝단부에 관통되어지며 상기 휠하우징패널(32)과 휠하우징보강패널(33) 사이에 고정설치되어 리어 서프펜션(10)을 보다 강하게 지지하여 결합강도를 높이고 리어 서스펜션(10)에서 전달되는 진동을 단절시킨다.The shock absorber pipe 34 is a hollow hollow pipe, which penetrates one end of the rear suspension 10 and is fixed between the wheel housing panel 32 and the wheel housing reinforcement panel 33. By supporting the suspension 10 more strongly, the coupling strength is increased and the vibration transmitted from the rear suspension 10 is cut off.
또한, 상기 휠하우징패널(32) 및 휠하우징보강패널(33)이 결합되는 상기 쿼터인너패널(31a)은 쿼터아웃터패널(31b)과 상호 결합되어 폐단면을 형성하는데, 종래에는 이 폐단면이 매우 커서 리어 서스펜션(10)으로부터 전달되는 충격하중을 견디기에 충분하지 않았다.In addition, the quarter inner panel 31a to which the wheel housing panel 32 and the wheel housing reinforcement panel 33 are coupled is mutually coupled to the quarter outer panel 31b to form a closed cross section. It was so large that it was not sufficient to withstand the impact loads transmitted from the rear suspension 10.
따라서, 상기 쿼터인너패널(31a)과 쿼터아웃터패널(31b)이 이루는 폐단면이 분할되도록 하여 그 부위의 결합강성이 증대되도록 상기 쿼터인너패널(31a)과 쿼터아웃터패널(31b) 사이에는 쿼터보강패널(31c)이 추가로 설치된다.Therefore, the quarter reinforcement is formed between the quarter inner panel 31 a and the quarter outer panel 31 b so that the closed end surface formed by the quarter inner panel 31 a and the quarter outer panel 31 b is divided so that the coupling rigidity of the portion is increased. The panel 31c is additionally installed.
이렇게 하면 상기 쿼터보강패널(31c)의 추가 설치로 인하여 쿼터부(31)의 강성이 증대되므로 상기 쿼터인너패널(31a)에 결합되는 휠하우징패널(32) 및 휠하우징보강패널(33)의 결합력 또한 우수해진다.In this case, since the rigidity of the quarter portion 31 is increased due to the additional installation of the quarter reinforcement panel 31c, the coupling force of the wheel housing panel 32 and the wheel housing reinforcement panel 33 coupled to the quarter inner panel 31a is increased. It also becomes excellent.
이상과 같은 본 발명의 리어 서스펜션부 고정구조에 의하면 리어 서스펜션(10)이 휠하우징패널(32) 및 휠하우징보강패널(33)에 의해서 2중으로 지지되므로 결합력이 증대되어 차체의 비틀림이 억제되어 특히 코너링시의 차체가 매우 안정된다.According to the rear suspension fixing structure of the present invention as described above, since the rear suspension 10 is supported by the wheel housing panel 32 and the wheel housing reinforcement panel 33 in duplicate, the coupling force is increased and the torsion of the vehicle body is suppressed. The car body at cornering is very stable.
또한, 상기 휠하우징패널(32)과 휠하우징보강패널(33) 사이에 설치된 쇽업쇼버파이프(34)에 의해 리어 서스펜션(10)에서 전달되는 진동이 저지되므로 승차감이 개선된다.In addition, since the vibration transmitted from the rear suspension 10 is prevented by the shock absorber pipe 34 installed between the wheel housing panel 32 and the wheel housing reinforcement panel 33, the riding comfort is improved.
상술한 바와 같이 본 발명에 따른 자동차용 리어 서스펜션부의 고정구조에 의하면, 차량의 리어 서스펜션이 리어플로워패널과 쿼터인너패널 사이에서 휠하우징패널 및 휠하우징보강패널을 매개로 2중으로 지지되므로 결합력이 매우 우수해지고 그로 인하여 차체의 비틀림강성 및 코너링시의 차체 안정성이 향상되는 특유의 효과가 있다.As described above, according to the fixed structure of the vehicle rear suspension unit according to the present invention, since the rear suspension of the vehicle is supported by the wheel housing panel and the wheel housing reinforcement panel twice between the rear floor panel and the quarter inner panel, the coupling force is very high. There is a distinctive effect that is excellent and thereby the torsional rigidity of the vehicle body and the vehicle body stability during cornering is improved.
또한, 휠하우징패널 및 휠하우징보강패널 사이에 별도의 쇽업쇼버파이프를 설치하여 리어 서스펜션을 지지하도록 함으로써 리어 서스펜션을 통해 전달되는 진동이 억제되는 부수적 효과가 있다.In addition, by installing a separate shock absorber pipe between the wheel housing panel and the wheel housing reinforcement panel to support the rear suspension, there is a side effect of suppressing vibration transmitted through the rear suspension.
