Description

분리된 외력 전달 경로를 갖는 차량용 현가장치{Suspension having separated transmitting forces paths in vehicle}Suspension having separated transmitting forces paths in vehicle

본 발명은 차량용 현가장치에 관한 것으로, 보다 상세하게는 외부로부터 차체로 전달되는 외력의 전달 경로를 분산시켜 줄 수 있도록 된 분리된 외력 전달 경로를 갖는 차량용 현가장치에 관한 것이다.The present invention relates to a vehicle suspension, and more particularly, to a vehicle suspension having a separate external force transmission path that can distribute the transmission path of the external force transmitted from the outside to the vehicle body.

일반적으로 자동차에는 노면으로의 충격 외에도 구동력, 제동력, 원심력 등 다양한 힘이 동시에 작용하여 차량의 상·하방향으로의 진동인 범프·바운싱(bump·bouncing), 차량의 좌우로의 진동인 러칭(lurching), 차량의 전·후로 진동하는 서징(surging), 상·하방향의 축을 중심으로 회전하는 요잉(Yawing), 좌·우방향의 축을 중심으로 회전하는 피칭(Pitching) 및 전·후방향의 축을 중심으로 회전하는 롤링(rolling) 등의 진동을 받게 된다.In general, in addition to the impact on the road surface, various forces such as driving force, braking force, and centrifugal force act simultaneously to bump and bouncing vibrations in the up and down direction of the vehicle, and the vibrations to the left and right sides of the vehicle. ), Vibrating surging before and after the vehicle, yawing rotating around the upper and lower axes, pitching rotating around the left and right axes, and the front and rear axes Vibration such as rolling, which rotates around the center, is received.

이에 따라, 이러한 다양한 진동을 흡수하기 위해 자동차의 현가장치에는 승차감과 주행안정성 및 선회특성을 고려하여 다양한 현가장치와 스프링시스템이 사용되는데, 이중 승용차의 경우 맥퍼슨 타입의 독립 현가 장치는 캠버 방향의 위치결정을 위해 설치 공간의 희생이 있는 어퍼아암이 필요없이 쇽업소버가 그 역할을 수행하므로 차실내공간을 크게 할 수 있는 잇점 때문에 주로 사용하게 되고 이는, 차륜의 허브와 결합된 너클과, 상기한 너클에 직립 결합됨과 더불어 차체에 결합된 스트러트어셈블리로 구성되되, 상기 스트러트 어셈블리는 차륜의 너클과 연결된 쇽업서버와, 이 쇽업서버의 상·하 스프링시트에 지지된 코일스프링 및 이 코일스프링의 내부에 삽입됨과 아울러 쇽업서버를 감싸도록 설치된 인슐레이터유니트로 구성되어 있다.Accordingly, in order to absorb such various vibrations, various suspension systems and spring systems are used in the suspension system of the vehicle in consideration of riding comfort, driving stability, and turning characteristics.In the case of dual passenger cars, the McPherson type independent suspension system is located in the camber direction. The shock absorber plays the role without the need of an upper arm at the expense of the installation space for the decision, so it is mainly used because of the advantage that the interior space can be enlarged, which is the knuckle combined with the hub of the wheel and the knuckle described above. The strut assembly is composed of a strut assembly coupled to the vehicle body and coupled to the vehicle body. The strut assembly includes a pull up server connected to a knuckle of a wheel, a coil spring supported by upper and lower spring seats of the pull up server, and an insert into the coil spring. In addition, it consists of an insulator unit that is installed to surround the setup server.

이에 따라, 차량이 주행하게 되면 타이어가 노면의 굴곡에 따라 승강함에 따라 현가장치의 스트러트어셈블리가 압축 및 이완되면서 노면으로부터의 충격을 흡수하는 작용을 하게 된다.Accordingly, when the vehicle travels, as the tire is lifted according to the curvature of the road surface, the strut assembly of the suspension device is compressed and relaxed to absorb the impact from the road surface.

이때, 이와 같은 맥퍼슨 타입 현가장치는 노면으로부터 발생하는 외력에 대한 상·하 하중을 거의 대부분 스트러트어셈블리의 인슐레이터유니트를 매개체로 해 차체로 전달되는데, 이는 상기 인슐레이터유니트가 가해지는 하중을 집중시켜 완충·흡수하도록 즉, 노면에 의한 외력인 스프링하중과 쇽업서버 댐퍼 하중 및 범퍼스토퍼 하중(쇽업서버의 로드를 우레탄 재질로 감싼 부위로서 이는, 쇽업서버의 로드가 승강할 때 쇽업서버의 충격을 완충시킬 때 발생됨)들이 각각 다른 방향으로부터 전달된 후 차체와 결합되는 인슐레이터유니트에 의해 집중되어 차체로 전달되는 특성이 있게 된다.At this time, the McPherson type suspension device transfers the upper and lower loads on the external force generated from the road surface almost to the vehicle body through the insulator unit of the strut assembly, which concentrates the load applied to the insulator unit and cushions and Spring loads and shock absorber loads and bumper stopper loads, which are the external forces caused by the road surface, are absorbed by the urethane material. Generated) are transmitted from different directions and then concentrated and insulated by an insulator unit coupled to the vehicle body.

그러나, 이와 같이 서로 다른 방향에서 전달되는 각 하중(스프링하중과 쇽업서버 댐퍼 하중 및 범퍼스토퍼 하중)들이 차체와 결합된 인슐레이터유니트로 집중되는 경우에는 특히, 상기 쇽업서버를 감싸고 있는 코일스프링에 의한 스프링하중은 차량의 스프렁 매스(Sprung Mass)에 관련된 1~3Hz에 이르는 주파수 특성인 반면, 상기 쇽업서버는 스프링 속도성분인 9Hz에서 서스펜션모드인 15Hz에 이르는 주파수 특성이 있게 되는데, 이와 같이 다양한 영역의 주파수가 모두 인슐레이터유니트로 집중되는 경우 각 하중별로 다른 특성을 모두 고려하여 보다 효과적으로 완충·흡수할 수 있는 인슐레이터유니트의 설계에 한계가 있는 단점이 있게 된다.However, when the loads (spring loads and shock absorber damper loads and bumper stopper loads) transmitted in different directions are concentrated in the insulator unit coupled with the vehicle body, the spring by the coil spring surrounding the shock absorber server is particularly important. The load has a frequency characteristic ranging from 1 to 3 Hz related to the sprung mass of the vehicle, whereas the shock-up server has a frequency characteristic ranging from 9 Hz as a spring velocity component to 15 Hz as a suspension mode. If all frequencies are concentrated in the insulator unit, there are limitations in the design of the insulator unit that can absorb and absorb more effectively considering all the different characteristics for each load.

또한, 이와 같은 인슐레이터유니트의 설계 한계성은 노면으로부터의 로드 노이즈(Noise) 저감과 승차감 향상을 위한 설계 제약 조건으로 작용하게 되고 이로 인해, 차량의 보다 향상된 성능 개발을 저해하는 단점이 있게 됨은 물론이다.In addition, the design limitation of such an insulator unit acts as a design constraint for reducing road noise and improving ride comfort from the road surface, and thus, of course, there is a disadvantage of inhibiting the improved performance of the vehicle.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량 주행중 노면에 의한 외력의 차체 전달시 매개체 역할을 하는 스트러트어셈블리가 하중의 전달 경로를 이원화해 전달 하중의 완충·흡수율을 높여 차체로 전달되어 발생되는 로드 노이즈를 저감하면서 차량 성능을 전체적으로 향상함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above, and the strut assembly, which serves as a medium when the external force is transmitted by the road surface while driving the vehicle, dualizes the transfer path of the load to increase the buffering / absorption rate of the transfer load and deliver it to the vehicle body. The purpose is to improve vehicle performance as a whole while reducing road noise generated.

상기와 같은 목적을 달성하기 위한 본 발명은, 차륜에 결합된 너클을 매개로 일단이 직립 결합되면서 그 타단이 차체에 결합된 스트러트어셈블리가 너클에 결합된 쇽업서버와, 이 쇽업서버를 감싸면서 상·하 스프링시트에 지지된 코일스프링 및 상기 쇽업서버를 차체에 결합하면서 코일스프링을 지지해 전달되는 하중을 완충·흡수하는 인슐레이터유니트로 구성되되, The present invention for achieving the above object, the striking assembly coupled to the vehicle body, one end is coupled upright through the knuckle coupled to the wheel, and the stand-up server coupled to the knuckle, It is composed of a coil spring supported by the lower spring seat and an insulator unit that supports the coil spring while absorbing and absorbing the load transmitted by coupling the shock-up server to the vehicle body.

이 인슐레이터유니트는 코일스프링을 지지해 코일스프링을 통해 전달되는 스프링외력을 차체로 전달하는 로워파트와, 쇽업서버로드부위를 감싼 우레탄 재질인 범퍼스토퍼가 수용된 범퍼지지브라켓에 적층되면서 차체로 결합되어 쇽업서버와 쇽업소버로드를 감싼 범퍼스토퍼를 통해 각각 전달되는 쇽업서버외력과 범퍼스토퍼외력을 차체로 전달하는 어퍼파트 및 상기 로워파트와 어퍼파트사이에 개재되어 차량 조향시 조향 작용을 발생하도록 하는 베어링으로 이루어진 것을 특징으로 한다. This insulator unit supports the coil spring and transfers the spring external force transmitted through the coil spring to the car body, and the bumper stopper, which is a urethane material wrapped around the pull-up server rod, is laminated on the bumper support bracket. It is a bearing that generates steering action when steering the vehicle interposed between the upper part and the lower part and the upper part which transmits the external force and the bumper stopper external force transmitted through the bumper stopper surrounding the server and the shock absorber rod to the vehicle body. Characterized in that made.

The bumper stopper 5, which is a urethane material wrapped around the rod 3a, is stacked on the bumper support bracket 6 in which the upper part 16 is coupled to the vehicle body.

그리고, 상기 로워파트(11)는 범퍼스토퍼(5)가 수용된 범퍼지지브라켓(6)에 결합된 스프링시트브라켓(12)과, 이 스프링시트브라켓(12)의 안쪽으로 덧대어져 코일스프링(4)인 안착되는 우레탄 재질인 로워인슐레이터(13)로 이루어지게 된다.The lower part 11 includes a spring seat bracket 12 coupled to the bumper support bracket 6 in which the bumper stopper 5 is accommodated, and is padded inwardly of the spring seat bracket 12 to form a coil spring 4. It is made of a lower insulator 13 which is a urethane material to be phosphorus seated.

또한, 상기 어퍼파트(16)는 범퍼스토퍼(5)가 수용된 범퍼지지브라켓(6)에 적층되면서 베어링(30)을 매개로 덧대어져 로워파트(11)의 스프링시트브라켓(12)에 서로 분리된 상태를 유지하는 인터지지브라켓(18)과, 쇽업소버(3)의 로드(3a)끝단을 결합한 체결너트(20)를 수용하면서 마운팅볼트(B)를 매개로 인터지지브라켓(18)과 함께 차체에 결합되는 어퍼지지브라켓(17) 및 상기 인터지지브라켓(18)의 내부 공간을 채우면서 쇽업소버(3)의 로드(3a)를 감싼 부쉬에 결합되는 우레탄 재질인 어퍼인슐레이터(19)로 이루어지게 된다.In addition, the upper part 16 is laminated on the bumper support bracket 6 in which the bumper stopper 5 is accommodated and padded through the bearing 30 so as to be separated from each other in the spring seat bracket 12 of the lower part 11. The body together with the inter support bracket 18 via the mounting bolt B while accommodating the inter support bracket 18 maintaining the state and the fastening nut 20 coupled to the end of the rod 3a of the shock absorber 3. An upper insulator (19) of urethane material coupled to a bushing that covers the rod (3a) of the shock absorber (3) while filling the inner space of the upper support bracket (17) and the inter support bracket (18) to be coupled to do.

여기서, 상기 어퍼지지브라켓(17)은 차체 패널 면에 덧대어지는 어퍼지지브라켓(17)의 접촉면과 쇽업서버(3)의 로드(3a)끝단이 체결되는 체결너트(20)를 수용하는 그 중앙 부위간에 소정 갭(G)을 이루면서 단차지도록 돌출보스(17a)를 형성하는데 이는, 차체에 체결되는 인슐레이터유니트가 쇽업서버(3)의 로드(3a)끝단을 함몰시킨 상태 즉, 상기 인슐레이터유니트가 쇽업서버(3)의 로드(3a)끝단을 그 안쪽으로 수용하면서 차체내부로 깊게 위치되는 구조에 비해 인슐레이터유니트가 쇽업서버(3)의 로드(3a)끝단을 그 안쪽으로 수용하지 않는 구조를 이루게 된다.Here, the upper support bracket 17 is a central portion for receiving the fastening nut 20 to which the contact surface of the upper support bracket 17, which is padded on the vehicle body panel surface, and the end of the rod 3a of the pull-up server 3 are fastened.

한편, 미 설명부호 T는 조향장치의 조작에 따라 차륜(W)의 방향을 제어하는 힘을 전달하는 타이로드이다.On the other hand, reference numeral T is a tie rod for transmitting a force for controlling the direction of the wheel (W) in accordance with the operation of the steering device.

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 맥퍼슨 타입 현가장치는 현가장치에서 필요로 하는 작용 즉, 차량이 주행하게 되면 타이어가 노면의 굴곡에 따라 승강함에 따라 현가장치의 스트러트어셈블리가 압축 및 이완되면서 노면으로부터의 충격을 흡수하는 작용을 하게 되지만, 주행중 노면으로부터 발생하는 외력에 대한 상·하 하중을 거의 대부분 완충·흡수하는 스트러트어셈블리의 하중 전달 작용이 스프링하중과 쇽업서버 댐퍼 하중 및 범퍼스토퍼 하중을 각각 분산시키면서 그 전달 경로를 달리해 차체로 전달되어진다.The McPherson type suspension device of the present invention absorbs the impact from the road surface as the suspension assembly is compressed and relaxed as the tire moves up and down according to the curvature of the road when the vehicle runs. However, the load transfer action of the strut assembly, which absorbs and absorbs most of the up and down loads from the road surface while driving, disperses the spring load, the damper server damper load, and the bumper stopper load. It is delivered to the car body.

즉, 주행중 노면에 의한 외력들의 스트러트어셈블리의 인슐레이터유니트(10)를 통한 차체로의 전달을 도 2를 참조로 상세히 설명하면, 먼저 상기 인슐레이터유니트(10)쪽으로 스프링(4)을 통한 스프링하중인 스프링외력(Fs)이 전달되면, 상기 인슐레이터유니트(10)의 로워파트(11)를 이루는 로워인슐레이터(13)를 통과해 차제쪽으로 전달되어진다.That is, the transmission of external forces by the road surface to the vehicle body through the insulator unit 10 by the road surface while driving will be described in detail with reference to FIG. 2. First, the spring being loaded through the spring 4 toward the insulator unit 10. When the external force Fs is transmitted, the external force Fs is transmitted to the vehicle body through the lower insulator 13 forming the lower part 11 of the insulator unit 10.

그리고, 상기 인슐레이터유니트(10)쪽으로 쇽업서버(3)를 통한 쇽업서버 댐퍼 하중인 쇽업서버외력(Fa)이 전달되면, 상기 인슐레이터유니트(10)의 어퍼파트(16)를 이루면서 쇽업서버(3)의 로드(3a)부위를 감싼 어퍼인슐레이터(19)를 통과해 차제쪽으로 전달되어진다. Then, when the shock absorber external force Fa of the shock absorber load through the shock absorber server 3 is transferred to the insulator unit 10, the shock absorber unit 10 forms the upper part 16 of the shock absorber unit 10. Passed through the upper insulator 19 wrapped around the rod 3a portion of the rod 3a.

또한, 상기 인슐레이터유니트(10)쪽으로 쇽업서버(3)의 로드(3a) 승강시 전달되는 범퍼스토퍼 하중인 범퍼스토퍼외력(Fb)이 전달되면, 상기 인슐레이터유니트(10)의 어퍼파트(16)를 이루면서 범퍼스토퍼(5)에 적층된 어퍼인슐레이터(19)를 통과해 차제쪽으로 전달되어진다. In addition, when the bumper stopper external force Fb, which is a bumper stopper load transmitted when the rod 3a of the shock-up server 3 moves up and down, is transferred to the insulator unit 10, the upper part 16 of the insulator unit 10 is transferred. It passes through the upper insulator 19 laminated | stacked on the bumper stopper 5, and is transmitted to a vehicle side.

이와 같이, 상기 인슐레이터유니트(10)쪽으로 전달되는 외력중 스프링외력(Fs)이 로워파트(11)를 통해 차체로 전달되고, 쇽업서버외력(Fa)과 범퍼스토퍼외력(Fb)이 어퍼파트(16)를 통해 차체로 전달되면, 상대적으로 저주파영역이면서 큰 하중인 스프링외력(Fs)과 상대적으로 고주파 영역이면서 작은 하중인 쇽업서버외력(Fa)과 범퍼스토퍼외력(Fb)을 보다 효과적으로 지지하면서 완충·흡수할 수 있는 스트러트어셈블리를 구성할 수 있게 됨은 물론이다.As such, the spring external force Fs of the external force transmitted to the insulator unit 10 is transmitted to the vehicle body through the lower part 11, and the shock-up server external force Fa and the bumper stopper external force Fb are upper parts 16. When it is transmitted to the car body, it is more efficient to support the spring external force (Fs), which is a relatively low frequency region and a large load, and the shock up server external force (Fa) and the bumper stopper external force (Fb), which are a relatively high frequency region and a small load. Of course, it is possible to construct an absorbable strut assembly.

한편, 차량이 조향이 이루어지는 경우 전륜 현가장치의 스트러트어셈블리에서도 조향 작용이 가능해야 하는데, 이는 상기 인슐레이터유니트(10)의 어퍼파트(16)와 로워파트(11)사이에 개재된 베어링(30)을 통해 이루어지게 됨은 물론이다. On the other hand, when the vehicle is steered, the steering action should be possible even in the strut assembly of the front wheel suspension device, which is to support the bearing 30 interposed between the upper part 16 and the lower part 11 of the insulator unit 10. Of course, it is through.
