Description

자동차의 후륜 현가장치Rear suspension of car

본 발명은 자동차의 현가장치에 관한 것으로, 특히 자동차의 후륜 현가장치에 관한 것이다.The present invention relates to a suspension of an automobile, and more particularly to a rear wheel suspension of an automobile.

예컨대, 자동차에 있어서의 서스펜션 시스템은 차체와 차륜사이에 위치되어 차체와 차륜사이의 상대운동을 기계적으로 적절히 조화시켜 주행중 노면으로부터 받는 진동과 충격을 흡수하여 승차감과 선회 안정성을 향상시키는 장치이다.For example, a suspension system in an automobile is a device positioned between the vehicle body and the wheels to mechanically balance the relative movement between the vehicle body and the wheels to absorb vibrations and shocks received from the road surface while driving to improve ride comfort and turning stability.

도 7은 종래의 세미 트레일링 아암 후륜 현가장치를 도시한 도면으로, 차체에 수직부시(2)로 설치되는 크로스 맴버(4)에 차륜(6)을 장착한 트레일링 아암(8)이 수평부시(10)로 연결 설치되어 후륜 현가장치(12)는 이루어지고 있다.7 is a view illustrating a conventional semi trailing arm rear wheel suspension in which a trailing arm 8 having a wheel 6 mounted on a cross member 4 installed as a vertical bush 2 on a vehicle body is a horizontal bush. The rear wheel suspension device 12 is provided by being connected by 10.

상기한 후륜 현가장치(12)는 선회시 차륜을 통해 횡강력(C.F)이 가해지는데, 이때 트레일링 아암(8)을 연결하고 있는 수평부시(10)의 변형에 의해 차륜(6)은 토 -아웃트(O) 상태에 이르게 되어 선회 주행하게 된다.The rear wheel suspension 12 is applied with a lateral force CF through the wheel when it turns, wherein the wheel 6 is deformed by a deformation of the horizontal bush 10 connecting the trailing arm 8. It reaches the out (O) state, and it turns and travels.

상기한 트레일링 아암(8)을 크로스멤버(4)에 연결하고 있는 수평부시(10)의 변형이 발생과, 크로스멤버(4)를 차체에 연결 설치하고 있는 수직부시(2)의 변형에 의해 차륜의 휠 센터가 접지점 a에서 a'로 후퇴하게 되면서 토-아웃트 상태가 된다.Deformation of the horizontal bush 10 connecting the trailing arm 8 to the cross member 4 occurs and deformation of the vertical bush 2 connecting the cross member 4 to the vehicle body. The wheel center of the wheel retracts from the ground point a to a 'and becomes toe-out.

이에 따라 트레일링 아암(8)과 크로스 멤버(4)는 우측으로 회전한 L위치로 자세 변위를 일으킨다.As a result, the trailing arm 8 and the cross member 4 cause posture displacement to the L position rotated to the right.

이는 핸들의 조향 정도에 비해 뒤쪽이 외측으로 과도하게 벗어나 주행하는 오버 스티어(over steer) 현상이 발생하게 된다.This results in an over steer phenomenon in which the rear side is excessively outwardly driven compared to the steering degree of the steering wheel.

이러한 종래기술은 차량의 선회시 토-아웃트에 따른 오버 스티어 현상이 발생하여 주행 안정성을 저해하며, 이로서 승차감을 떨어뜨리는 문제점이 있었다.Such a prior art has a problem of oversteering due to the toe-out when the vehicle is turning, which hinders driving stability, thereby lowering the riding comfort.

본 발명의 목적은 후륜 현가장치의 구성 및 장착위치를 개선하여 공간확보, 선회안정성 및 중량감소를 도모한 자동차의 후륜 현가장치를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a rear wheel suspension device for an automobile, which has improved space configuration, mounting position, and secures space, turning stability, and weight reduction.

The left mounting bush 34 and the right mounting bush are inserted into the fastening part 48 of the left holder part 32 and the right holder part to be fastened by bolts 46, and bush mountings formed on the vehicle body by forming the insert part. It is made of a portion 52.

도 6을 참조하여 본 발명의 실시예에 따른 후륜 현가장치(36)의 동작을 설명한다.6, the operation of the rear wheel suspension 36 according to the embodiment of the present invention will be described.

먼저, 자동차의 주행중 횡력(C.F)이 좌측 아암(22)으로 전달되는 상태로 가정하면, 스테빌라이저 바아(30)를 설치하고 있는 좌측 장착부시(34)와 좌측 홀더부 (32)는 부시 마운팅부(52)와 고무부시(26, 40)의 변형으로 포인트 a에서 a'로 이동하게 되고 반대측도 동일하게 변위된다.First, assuming that the lateral force CF is transmitted to the left arm 22 while driving the vehicle, the left mounting bush 34 and the left holder 32, which are provided with the stabilizer bar 30, are bush mounted parts. The deformation of the 52 and the rubber bushes 26, 40 moves from point a to a 'and displaces the opposite side equally.

즉, 자동차의 주행중인 상태에서 좌측 아암(22)의 위치는 도 6에 도시된 바와 같이 실선으로 도시된다. 이러한 상태에서 횡력(C.F)이 좌측 아암(22)으로 전달되는 상태이면, 좌측 아암(22)의 위치는 차륜(20)과 연결되는 포인트 b가 b'로 위치 이동되고, 좌측 아암(22)에 연결되는 스테빌라이저 바아(30)는 도 6에 도시된 바와 같이 일점 쇄선의 위치로 이동된다.That is, the position of the left arm 22 in the running state of the vehicle is shown by the solid line as shown in FIG. In this state, when the lateral force CF is transmitted to the left arm 22, the position of the left arm 22 is moved to the point b ', which is connected to the wheel 20, to b', and to the left arm 22. The stabilizer bar 30 to be connected is moved to the position of the dashed-dotted line as shown in FIG.

결국, 차륜(20)은 도 6에 도시된 바와 같이 토-인(Ⅰ) 상태가 되어 자동차의 주행 안정성을 유지하게 된다As a result, the wheel 20 is in a to-in (I) state as shown in FIG. 6 to maintain driving stability of the vehicle.

한편, 차체의 롤링시 좌측 아암(22)은 스테빌라이저 바아(30)에 고무부시 (26)를 개재하여 연결되고 있는 연결부(28)에 의해 변위가 이루어지면서 발생하는 스테빌라이저 바아(30)의 비틀림에 의해 롤링이 감쇄되어 차체의 평형 유지를 도모하게 된다.On the other hand, when the vehicle body is rolled, the left arm 22 is twisted by the stabilizer bar 30 generated when the displacement is made by the connecting portion 28 connected to the stabilizer bar 30 via the rubber bush 26. Rolling is attenuated by this, and it aims at maintaining the equilibrium of a vehicle body.

상기한 바와 같이 본 발명의 실시예에 따른 자동차의 후륜 현가장치는 차체에 부시로 장착되는 스테빌라이저 바아에 차륜을 지자하는 아암을 설치하여 공간확보와 선회시 안정성 증대 및 중량감소를 도모하는 효과가 있다.As described above, the rear suspension of the vehicle according to the embodiment of the present invention has an effect of securing the space, increasing stability and reducing weight by installing an arm supporting the wheel on the stabilizer bar mounted to the vehicle body as a bush. have.
