Description
본 발명은 자동차용 맥퍼어슨식 독립현가현가장치에 관한 것으로, 특히 코일스프링의 장착위치가 변경되어 차체하중에 의한 노면의 반력 또는 노면으로 부터 전달되는 충격하증의 상태가 임의적으로 조절가능해짐으로 인해 쇽업소버에 발생되는 굽힘모멘트가 제거됨은 물론, 쇽업소버의 실린더내벽과 쇽업소버피스톤과의 마찰이 저감되도록 된 자동차용 맥퍼어슨식 독립현가현가장치에 관한 것이다.The present invention relates to a McPherson independent suspension system for automobiles, in particular, because the mounting position of the coil spring is changed, so that the reaction force of the road surface due to the vehicle load or the state of impact loading transmitted from the road surface can be arbitrarily adjusted. The present invention relates to a McPherson independent suspension system for automobiles, in which the bending moment generated in the shock absorber is eliminated and friction between the cylinder inner wall of the shock absorber and the shock absorber piston is reduced.
일반적으로 현가장치는 차측과 차체를 연결하여 주행할 때 노면에서 받는 진동이나 충격을 차체에 직접 전달되지 않도록 하여 차체나 하물의 손상을 방지하고 승차감을 좋게 하는 장치로써, 전방현가장치는 제1도에 도시된 바와 같이, 노면에서 받는 충격을 완화하도록 된 코일스프링(100)과, 이 코일스프링(100)의 자유진동을 억제하여 승차감을 좋게 하도록 된 쇽업소버(200)와, 언더바디의 강도 및 강성을 증진시키도록 된 크로스멤버(300)와, 휠의 움직임을 조절하도록 된 위암과 아래암(400 ; 이하 로어암이라 함) 및, 자동차가 옆으로 흔들리는 것을 방지하도록 된 스테빌 라이저 (500)등으로 구성되어 있다.In general, the suspension system is a device that prevents damage to the vehicle body or the load and improves the riding comfort by preventing the vibration or shock received from the road surface from being directly transmitted to the vehicle body when driving by connecting the vehicle side and the vehicle body. As shown in FIG. 6, the coil spring 100 is configured to mitigate the impact received from the road surface, the shock absorber 200 is configured to suppress the free vibration of the coil spring 100 to improve ride comfort, and the strength of the underbody and Crossmember 300 to increase rigidity, upper and lower arms (hereinafter referred to as 400 lower arm) to adjust the movement of the wheel, stabilizer 500 to prevent the vehicle from shaking sideways, etc. It consists of.
이러한 전방현가장치는 앞차축의 형식에 따라 차축현가식과 독립현가식으로분류되고, 상기 독립현가식은 전방현가장치에서 가장 널리 쓰이는 위시본형과, 리이프 스프링을 가로로 설치하여 어퍼암 또는 로어서스펜션암의 작용을 스프링이 겸하도록 된 가로놓인 리이프 스프링 형과, 후방으로 향한 1개 또는 2개의 압에 의해 바퀴를 지지하도록 된 트레일링 링크형 및, 코일스프링이 설치된 스트럿을 이용하는 맥퍼어슨형으로 분류된다.These front suspensions are classified into axle suspension and independent suspension type according to the type of front axle. The independent suspension type is the most widely used wishbone type in the front suspension system and the relief spring is installed horizontally for the upper arm or the lower suspension arm. It is classified into a cross-type leaf spring type for acting as a spring, a trailing link type for supporting the wheel by one or two pressures facing backwards, and a McPherson type using a strut with a coil spring. .
여기서, 차체에 장착되는 쇽업소버의 장착점이 높아 얼라이먼트(Alignment)가 정확히 설정되며, 또한 그의 변화도 적어 노면으로 부터의 충격을 광법위하게 분산시킬 수 있도록 된 상기 맥퍼어슨식 독립현가장치의 종래 구조는 제2도에 도시된 바와 같이, 자동차의 전체적인 골격을 이루도록 된 서브프레임(1)과, 이 서브프레임(1)과 결합됨과 더불어 서스펜션암중 하부에 설치되도록 된 로어컨트롤링크(7)와, 이 로어컨트롤링크(2)와 결합됨과 더불어 너클을 지지하도록 된 너클지지부재(3)와, 이 너클지지부재(3)와 결합됨과 더불어 노면으로 부터 전달되는 충격하중을 흡수하기 위해 쇽업소버실린더(4a) 및 쇽업소버피스톤로드(4b)로 이루어진 쇽업소버(4)의 하단을 지지하도록 된 쇽업소버지지부재(5)와, 상기 쇽업소버실린더(4a)에 부착된 하단시이트(6)와 쇽업소버피스톤로드(4b)에 부착된 상단시이트(7)사이에 설치되어 충격력을 흡수하도록 된 코일스프링(8)과, 상기 상단시이트(7)의 하부인 쇽어보버피스톤로드(4b)에 부착되어 충격력에 의해 현가장치의 파손을 방지하도록 된 충격흡수부재(9)와, 차체(17)에 결합되어 현가장치의 상단부를 지지하도록 된 현가 서포오트(11)로 이루어져 있다.Here, the conventional structure of the McPherson's independent suspension device that the alignment point of the shock absorber to be mounted on the vehicle body is high, and the alignment is set accurately, and the change thereof is also small so that the impact from the road surface can be widely distributed. As shown in FIG. 2, the subframe 1 is configured to form the overall skeleton of the vehicle, the lower control link 7 coupled to the subframe 1 and installed at the lower part of the suspension arm, and A knuckle support member 3 coupled to the lower control link 2 and supporting the knuckle, and a shock absorber cylinder 4a coupled to the knuckle support member 3 to absorb shock loads transmitted from the road surface. And a shock absorber support member (5) adapted to support the lower end of the shock absorber (4) consisting of the shock absorber rod (4b), and the lower sheet (6) attached to the shock absorber cylinder (4a). It is attached between the upper spring (7) attached to the sober piston rod (4b) and the coil spring (8) to absorb the impact force, and attached to the shock absorber piston rod (4b) that is the lower portion of the upper sheet (7) The shock absorbing member 9 is configured to prevent the suspension from being damaged by the impact force, and the suspension support 11 is coupled to the vehicle body 17 to support the upper end of the suspension.
따라서 차체(10)의 하중에 의한 노면의 반력 또는 노면으로 부터 전달된 충격하중이 바퀴를 통해 쇽업소버(4)에 전달되면, 이 충격하중은 쇽업소버실린더(4a)와 쇽업소버피스톤로드(4b)와의 상호작동과 코일스프링(8)의 탄성력 및 충격흡수부재(9)에 의해 감쇄되어 상기 차체(10)로 전달되는 충격하중은 극히 미약하게 된다.Therefore, when the reaction force of the road surface due to the load of the vehicle body 10 or the impact load transmitted from the road surface is transmitted to the shock absorber 4 through the wheel, the shock load is the shock absorber cylinder 4a and the shock absorber rod 4b. ) And the impact load attenuated by the elastic force of the coil spring 8 and the shock absorbing member 9 and transmitted to the vehicle body 10 is extremely weak.
그러나 이와 같은 구조로 된 종래의 맥퍼어슨식 독립현가장치에 의하면, 코일스프링(8)의 상단부가 상단시이트(7)를 매개로 차체(10)와 밀접된 현가서포오트(11)에 설치됨과 더불어 하단부는 하단시이트(6)를 매개로 쇽업소버실린더(4a)의 소정부위에 설치됨으로 인해 현가서포오트(11)가 결합된 차체(10)의 높이가 노면으로 부터 높게 위치되어 주행시 안정성이 저하되는 문제점이 있었다.However, according to the conventional McPherson type independent suspension device having such a structure, the upper end of the coil spring 8 is installed on the suspension support 11 which is in close contact with the vehicle body 10 via the upper sheet 7. Since the lower end is installed at a predetermined portion of the shock absorber cylinder 4a via the lower seat 6, the height of the vehicle body 10 to which the suspension support 11 is coupled is positioned high from the road surface, thereby deteriorating stability during driving. There was a problem.
즉, 상기 코일스프링(S)이 쇽업소버(4)의 전체길이중 2/3이상에 걸쳐 설치됨으로 인해 상기 쇽업소버(4)를 설치됨으로 인해 상기 쇽업소버(4)를 설치하기 위해 서는 많은 공간이 필요할 뿐만 아니라 이로 인해 노면과 차체(10)와의 높이(H)가 높아짐으로써 실내공간이 줄어드는 문제점이 있었다.That is, since the coil spring S is installed over 2/3 of the total length of the shock absorber 4, the shock absorber 4 is installed, so that the shock absorber 4 is installed. Not only this is necessary, but due to this, the height H between the road surface and the vehicle body 10 is increased, thereby reducing the indoor space.
또한, 상기 코일스프링(8)과 쇽업소버(4)가 같이 설치되면, 상기 쇽업소버(4)의 작동시 코일스프링(8)이 휘어지려는 성질에 의해 쇽업소버(4)에는 굽힘모멘트가 발생되는 바, 이때 쇽업소버실린더(4a)의 내벽과 쇽업소버피스톤(도시되어있지 않음)에는 마찰력이 발생되어 현가장치로서의 기능이 저하됨으로 인해 탑승자의 승차감이 저하되는 문제점이 있었다.In addition, when the coil spring 8 and the shock absorber 4 are installed together, a bending moment is generated in the shock absorber 4 due to the property of the coil spring 8 to bend during operation of the shock absorber 4. At this time, the inner wall of the shock absorber cylinder (4a) and the shock absorber piston (not shown) has a problem that the riding comfort of the occupant is reduced due to the deterioration of the function as a suspension device.
이에 본 발명은 상기와 같은 모든 문제점들을 해소하기 위해 안출된 것으로, 상단지지점이 서브프레임과 결합된 사이드멤버 또는 서브프레임에 위치됨과 더불어 하단지지점이 쇽업소버지지부재에 위치되도록 코일스프링을 설치하여, 노면과 차체와의 높이를 줄임으로써 주행중 안정성이 향상될 뿐만 아니라 노면으로 부터 전달되는 충격하중의 하중분포상태가 쇽업소버의 하단이나 서브프레임 또는 차체의 하단으로 변경됨으로 인해 쇽업소버의 굽힘모멘트가 제거됨과 더불어 쇽업소버실린더와 쇽업소버피스톤과의 마찰혁이 제거되어 원활한 현가기능이 수행됨으로써 숭차감이 향상되도록 더된 자동차용 맥퍼어슨식 독립현가현가장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve all the above problems, by installing a coil spring so that the upper support point is located in the side member or subframe combined with the subframe, and the lower support point is located in the shock absorber support member, By reducing the height between the road surface and the body, the stability during driving is improved, and the bending moment of the shock absorber is eliminated because the load distribution state of the impact load transmitted from the road surface is changed to the bottom of the shock absorber, the subframe or the bottom of the body. In addition, the purpose of the present invention is to provide a McPherson-independent suspension suspension for automobiles, which has been improved to improve the sense of worship by removing frictional friction between shock absorber cylinder and shock absorber piston.

And the shock absorber supporting member (5) adapted to support the lower end of the shock absorber (4), which is composed of a shock absorber cylinder (4a) and a shock absorber rod (4b) to absorb the shock load transmitted from the road surface. A coil spring 8 installed between the lower sheet 6 attached to the shock absorber cylinder 4a and the upper sheet 7 attached to the shock absorber rod 4b to absorb the layer force; The lower part of the upper sheet 7 The shock absorbing member 9 attached to the buffy stone rod 4b to prevent the suspension from being damaged by the impact force, and the suspension support 11 coupled to the vehicle body 10 to support the upper end of the suspension device. In the McPherson independent suspension system for automobiles, the load distribution of the impact load that the lower sheet 6 supported by the lower part of the coil spring 8 and the upper sheet 7 supported by the upper part are transmitted from the road surface. In order to change the state, the lower sheet 6 is attached to the shock absorber supporting member 5 and the upper sheet 7 is attached to the side member 12 coupled to the upper portion of the subframe 1.
따라서, 노면으로 부터 전달되는 충격하중이 바퀴를 통해 쇽업소버(4)로 전달되면, 상기 쇽업소버(4)의 전체에 걸쳐 분포되었던 충격하중의 하중분포가 상기 쇽업소버(4)의 하단이나 서브프레임(1) 또는 차체(le)의 하단으로 변경됨으로 인해 상기 쇽업소버의 작동시 굽힘모멘트가 제거되어 쇽업소버실린더(4a)와 쇽업소버피스톤과의 마찰적이 제거될 뿐만 아니라 이로 인해 현가기능이 원활하게 수행되게된다.Therefore, when the impact load transmitted from the road surface is transmitted to the shock absorber 4 through the wheels, the load distribution of the impact load that has been distributed throughout the shock absorber 4 is lowered or serves as the lower end of the shock absorber 4. Due to the change to the lower end of the frame 1 or the vehicle body (le), the bending moment is removed during operation of the shock absorber, which not only eliminates friction between the shock absorber cylinder 4a and the shock absorber piston, but also suspends the suspension function smoothly. To be done.
또한, 상기 코일스프링(8)의 상단지지점인 상단시이트(7)가 사이드멤버(12)에 부착됨으로 인해 쇽업소버(4)의 전체길이를 짧게 제작할 수 있게 되어 노면과 차체(10)와의 높이(h)가 낮아짐은 물론, 이로 인해 주행안정성이 향상되게 된다.In addition, since the upper sheet 7, which is the upper support point of the coil spring 8, is attached to the side member 12, the entire length of the shock absorber 4 can be made short, so that the height of the road surface and the vehicle body 10 ( h) is lowered, of course, the driving stability is improved.
이상 설명한 바와 같이 본 발명에 의하면, 자동차의 전체적인 골격을 이루도록 된 서브프레임, 서스펜션암중 하부에 설치되도록 된 로어컨트롤링크, 너클을 지지하도록 된 너클지지부재, 노면으로 부터 전달되는 충격하중을 흡수하기 위해 쇽업소버실린더 및 쇽업소버피스톤로드로 이루어진 쇽업소버의 하단을 지지하도록 된 쇽업소버지지부재, 이 쇽업소버지지부재에 부착된 하단시이트와 사이드멤버에 부착된 상단시이트사이에 설치되어 충격력을 흡수하도록 된 코일스프링, 충격력에 의해 현가장치의 파손을 방지하도록 된 충격흡수부재, 차체에 결합되어 현가장치의 상단부를 지지하도록 된 현가서포오트로 이루어져, 노면으로 부터 전달되는 충격하중의 하중분포가 상기 쇽업소버의 하단이나 서브프레임 또는 차체의 하단으로 변경됨으로 인해 상기 쇽업소버의 작동시 굽힘모멘트가 제거되어 쇽업소버실린더와 쇽업소버피스톤과의 마찰력이 제거될 뿐만 아니라 이로 인해 현가기능이 원활하게 수행되고, 상기 코일스프링의 상단지지점인 상단시이트가 사이드멤버에 부착됨으로 인해 쇽업소버의 전체길이를 짧게 제작할 수 있게 되어 노면과 차체와의 높이가 낮아짐은 물론 주행안정성이 향상되는 효과가 있다.As described above, according to the present invention, in order to absorb the impact load transmitted from the subframe that forms the overall skeleton of the vehicle, the lower control link that is to be installed in the lower portion of the suspension arm, the knuckle support member that supports the knuckle, and the road surface. The shock absorber support member is designed to support the lower end of the shock absorber, which consists of the shock absorber cylinder and the shock absorber piston rod, and is installed between the lower sheet attached to the shock absorber support member and the upper sheet attached to the side member to absorb impact force. The coil spring, the shock absorbing member to prevent the suspension from being damaged by the impact force, and the suspension support coupled to the vehicle body to support the upper end of the suspension system, and the load distribution of the impact load transmitted from the road surface is the shock absorber. To the bottom of, or to the bottom of a subframe or bodywork The bending moment is removed during operation of the shock absorber to remove frictional force between the shock absorber cylinder and shock absorber piston, and thus the suspension function is smoothly performed, and the upper sheet, which is the upper support point of the coil spring, is attached to the side member. Due to this, the overall length of the shock absorber can be made short, and the height between the road surface and the body is lowered, and driving stability is also improved.
