Abstract

PURPOSE: A rear suspension of a vehicle is provided to efficiently use the interior space of a vehicle by placing a rear seat freely, and to improve the traveling experience by continuously absorbing shocks. CONSTITUTION: A rear suspension of a vehicle includes an upper arm(20) installed on the upper portion of a wheel center(11) and a lower arm(30) installed on the lower portion of the wheel center. Two installation points(21,22,31,32) are formed on both ends of respective arms. The arms are fixed on the wheel via the installation points. The upper arm is horizontal to the lower arm. Both arms are upward inclined. The pitching center is limitless, and is placed in the wheel center. When a tire rides over a protrusion, the movement trajectory of the wheel center is moved backward. The wheel center is changed continuously. Therefore, the suspension absorbs shocks.

Description

후륜 현가 장치{Rear suspension apparatus}Rear suspension apparatus

본 발명은 후륜 현가 장치에 관한 것으로서, 특히 돌출물 통과시 충격 완화가 가능한 구조의 후륜 현가 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear wheel suspension device, and more particularly, to a rear wheel suspension device having a structure capable of mitigating shock when passing through a protrusion.

차량의 후륜 현가 장치(rear suspension apparatus)는 도 1에 도시된 바와 같이 이중 위시본(double wishbone) 또는 다중 링크(multi link) 형태로 구성되어있다. 후륜 현가 장치는 휠 중심(1)을 기준으로 상부에 장착되어 있는 상부 암(2) 및 하부에 장착되어 있는 하부 암(3)을 포함한다. 각 암(2 및 3)에는 양단에 2개의 장착점(2-1, 2-1 및 3-1, 3-2)이 형성되어 있어 각 암(2 및 3)은 휠에 고정된다.The rear suspension apparatus of the vehicle is configured in the form of a double wishbone or multi link as shown in FIG. 1. The rear wheel suspension comprises an upper arm 2 mounted on the upper side and a lower arm 3 mounted on the lower side with respect to the wheel center 1. Each arm 2 and 3 has two mounting points 2-1, 2-1 and 3-1, 3-2 at both ends, so that each arm 2 and 3 is fixed to the wheel.

각 암(2 및 3)은 전방을 향하여 일정각도 경사진 상태이며, 따라서 각 암(2 및 3)의 연장선은 축 중심으로부터 일정 거리(L) 떨어진 점에서 만나게 되며, 이를 피칭 중심(PC; pitching center)이라 한다. 이 피칭 중심(PC)은 휠 중심(1)과 거의 수평 상태를 유지한다.Each of the arms 2 and 3 is inclined at an angle toward the front, so that the extension lines of the arms 2 and 3 meet at a distance L from the center of the axis, which is the pitching center PC. center). This pitching center PC is kept substantially horizontal with the wheel center 1.

이러한 현가 장치가 장착된 후륜(R)이 도 2에 도시된 바와 같이 돌기물(P)을 통과할 때, 타이어에 가해지는 충격에 의하여 휠은 상하운동을 하게 된다. 이때, 도 1에 도시된 휠 중심(1)의 궤적은 초기에 충격을 흡수할 수 있는 후방을 향하며, 그 후에는 전방을 향하게 된다. 휠 중심의(1) 궤적이 전방으로 이동하는 경우에 충격을 흡수하는 것보다는 그 반대로 휠에 충격을 가하게 된다. 결국, 타이어가 돌기물을 통과할 때 휠에 충격이 가해짐으로서 승차감이 나빠지는 문제가 발생하게 된다.When the rear wheel (R) equipped with such a suspension device passes through the projection (P) as shown in Figure 2, the wheel is moved up and down by the impact applied to the tire. At this time, the trajectory of the wheel center 1 shown in FIG. 1 is directed toward the rear to initially absorb the shock, and then to the front. When the trajectory of the wheel center 1 moves forward, the wheel is impacted instead of absorbing the shock. As a result, when the tire passes through the projection, the wheel is subjected to an impact, thereby causing a problem of deterioration of ride comfort.

본 발명은 차량의 후륜에 장착된 현가 장치에서 발생하는 상술한 문제점을 해결하기 위한 것으로서, 상부 암과 하부 암의 장착 위치를 변경함으로서 휠 중심의 이동 궤적을 항상 후방으로 유지할 수 있는 현가 장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems occurring in the suspension device mounted on the rear wheel of the vehicle, providing a suspension device that can always maintain the movement trajectory of the wheel center to the rear by changing the mounting position of the upper arm and the lower arm. Its purpose is to.

상술한 목적을 실현하기 위한 본 발명은 후륜 타이어가 돌기물을 통과할 때휠 중심이 후방으로만 이동하게 함으로서 계속적으로 충격을 흡수할 수 있게 구성하였다. 본 발명에 따른 후륜 현가 장치는 하부 암과 하부 암은 서로 수평 상태를 유지하며, 전방을 향하여 상향 경사진 상태로 장착되어 상부 암과 하부 암의 연장선은 서로 만나지 않게 되며, 그 연장선은 휠 중심 위에 위치하게 함으로서 이루어진다.The present invention for realizing the above object is configured to continuously absorb the shock by allowing the wheel center to move only rearward when the rear tire passes through the projection. In the rear suspension according to the present invention, the lower arm and the lower arm remain horizontal to each other, and are mounted in an inclined upward direction toward the front so that extension lines of the upper arm and the lower arm do not meet each other, and the extension line is on the wheel center. By positioning it.

이하, 본 발명을 첨부한 도면을 참고하여 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings of the present invention will be described in more detail.

도 3은 본 발명에 따른 후륜 현가 장치의 개략적인 구성도로서, 본 발명에 따른 후륜 현가 장치의 가장 큰 특징은 피칭 센터가 무한대이며, 휠 중심 연장선 위에 형성된다는 점이다.3 is a schematic configuration diagram of a rear wheel suspension according to the present invention, the biggest feature of the rear wheel suspension according to the present invention is that the pitching center is infinite, and is formed on the wheel center extension line.

본 발명에 따른 후륜 현가 장치 역시 휠 중심(11)을 기준으로 상부에 장착되어 있는 상부 암(20) 및 하부에 장착되어 있는 하부 암(30)을 포함한다. 각 암(20 및 30)에는 양단에 2개의 장착점(21, 22 및 31, 32)이 형성되어 있어 각 암(20 및 30)은 휠에 고정된다.The rear wheel suspension according to the present invention also includes an upper arm 20 mounted on the upper portion and a lower arm 30 mounted on the lower portion of the wheel center 11. Each arm 20 and 30 is provided with two mounting points 21, 22, 31 and 32 at both ends so that each arm 20 and 30 is fixed to the wheel.

상부 암(20)과 하부 암(30)은 서로 수평 상태를 유지하며, 동시에 전방을 향하여 상향 경사진 상태로서, 각 암(20 및 30)의 연장선은 서로 만나지 않게 된다. 즉, 피칭 중심은 무한대이며, 휠 중심(11) 위에 위치한다.The upper arm 20 and the lower arm 30 are horizontal to each other and at the same time inclined upward toward the front, the extension lines of the respective arms 20 and 30 do not meet each other. That is, the pitching center is infinity and is located above the wheel center 11.

이와 같은 현가 장치를 장착한 상태에서 타이어가 도 1과 같은 돌기물(P)을 통과할 때, 휠 중심(11)의 이동 궤적은 직선적으로 후방이동이 가능하게 된다. 즉, 상부 암(20)과 하부 암(30)이 전방을 향하여 상향 경사진 상태로 장착되고 또한 서로 평행을 유지하기 때문에 돌기물(P)을 통과할 때 휠 중심(11)의 이동은 계속적으로 후방을 향하여 이루어지게 된다. 따라서 현가 장치는 충격을 흡수할 수 있게 되는 것이다.When the tire passes through the projection P as shown in FIG. 1 in the state in which the suspension device is mounted, the movement trajectory of the wheel center 11 can be linearly moved backward. That is, since the upper arm 20 and the lower arm 30 are mounted in an inclined upward direction and are kept in parallel with each other, the movement of the wheel center 11 continuously continues when passing through the projection P. Towards the rear. Therefore, the suspension device can absorb the shock.

한편, 돌기물을 통과할 때 휠 중심이 후방으로만 이동하기 때문에 도 4에 도시된 바와 같이 후석(점선 부분)을 보다 후방으로 이동(실선 부분)시킬 수 있어 차량 실내 공간의 확대할 수도 있음은 물론이다.On the other hand, since the center of the wheel is moved only backward when passing through the projections, as shown in Figure 4 it is possible to move the rear seats (dotted line portion) more rearward (solid line portion) can be enlarged the interior space of the vehicle Of course.

이상과 같은 본 발명은 후륜 타이어가 돌기물을 통과할 때 휠 중심이 후방으로만 이동하기 때문에 계속적으로 충격을 흡수할 수 있어 차량의 승차감을 향상시킬 수 있으며, 후석의 배치를 보다 여유롭게 함으로서 실내 공간을 넓게 이용할 수 있다.As described above, the present invention can continuously absorb shock because the wheel center moves only rearward when the rear tire passes through the projections, thereby improving the riding comfort of the vehicle and making the rear seat arrangement more comfortable. Can be widely used.
