Description

댐퍼를 장착한 리어 현가장치Rear suspension with damper

본 고안은 댐퍼를 장착한 리어 현가장치에 관한 것으로서 특히 자동차의 차체 프레임 일측에 댐퍼를 구성하여 판 스프링과 연결하여 구성함으로서 차체에 전달되는 충격을 감소시키는 댐퍼를 장착한 리어 현가장치에 관한 것이다.The present invention relates to a rear suspension equipped with a damper, and more particularly to a rear suspension equipped with a damper to reduce the shock transmitted to the vehicle body by forming a damper on one side of the vehicle body frame connected to the leaf spring.

일반적으로 자동차의 현가장치는 자동차의 주행중에 바퀴를 통하여 노면으로부터의 진동이나 충격을 끊임없이 받는다.In general, the suspension of a vehicle is constantly subjected to vibration or shock from the road surface through the wheel while the vehicle is driving.

이 때문에 프레임과 차축 사이에 완충 장치를 설치하여 충격이나 진동이 직접 프레임에 전달되는 것을 방지하여 승차감을 향상시키고, 적재물을 보호하고, 무리한 충격으로 인한 차체 각부의 파손을 방지하고 있다.For this reason, a shock absorber is installed between the frame and the axle to prevent shock or vibration from being transmitted directly to the frame, thereby improving ride comfort, protecting loads, and preventing damage to the body parts due to excessive impact.

또 바퀴의 불규칙한 진동을 억제시켜 주행 안전을 향상시키고 있다.It also improves driving safety by suppressing irregular vibrations of the wheels.

이러한 완충 장치를 포함하여 프레임과 차축 사이를 연결하고 있는 기구를 현가장치(Suspension System)라 한다.The mechanism that connects the frame and the axle, including such a shock absorber, is called a suspension system.

상기 현가장치는 구동 바퀴의 구동력, 제동시의 제동력 등을 프레임에 전달하고, 또 선회시 원심력을 이겨 차체의 균형을 이루는 역할도 하는바, 다음과 같은 현가장치의 구비 조건을 같고 있다.The suspension device transmits the driving force of the driving wheel, the braking force at the time of braking to the frame, and also serves to balance the vehicle body by defeating the centrifugal force at the time of turning, and the following suspension conditions are the same.

첫째, 노면으로부터의 충격을 완화하기 위해 상,하 방향의 움직임은 적당한 유연성이 있어야 한다.First, in order to alleviate the impact from the road surface, the up and down movements must have adequate flexibility.

둘째, 구동력, 제동력, 원심력 등에 견디기 위해서는 전후, 좌우 방향으로 적당한 강성이 있어야 한다.Second, in order to withstand the driving force, braking force, centrifugal force, etc., there must be adequate rigidity in the front, rear, left and right directions.

그러나 이 두가지의 조건, 즉 유연성과 강성은 서로 상반되므로 적절한 조화가 필요하다.However, these two conditions, flexibility and stiffness, are in opposition to each other, so proper harmonization is necessary.

상기와 같은 목적을 갖는 현가장치중 리어 현가장치(rear Suspension)는 앞 현가장치와 같이 노면으로부터의 충격을 완화시키는 장치이며, 종류에는 차축 현가식과, 독립 현가식이 있다.Among the suspension devices having the above-mentioned purpose, rear suspension is a device that mitigates the impact from the road surface, like the front suspension, and includes axle suspension and independent suspension.

상기 차축 현가식은 뒷바퀴 구동의 중, 대형 차량에 주로 사용되며, 리어 액슬 하우징과 리어 액슬 샤프트로 구성되어 있고, 하우징이 중량을 지지하는 전부등식의 판 스프링이 구성되는 것이다.The axle suspension type is mainly used for medium and large vehicles of the rear wheel drive, and is composed of a rear axle housing and a rear axle shaft, and an all-equal leaf spring in which the housing supports weight is configured.

또한, 독립 현가식은 앞 현가장치와 같이 차축 현가식은 좌우 양 바퀴가 1개의 액슬에 의해 연결되어 있는 것에 반하여 독립 현가식은 좌우 양 바퀴가 독립하여 작용하며 프런트측과 다른 것은 일반적으로 스티어링(조향) 기구가 없고, 뒷바퀴 구동인 경우 동력 전달 기구가 있는 점이다.In addition, the independent suspension is the same as the front suspension, and the axle suspension is connected to both left and right wheels by one axle, while the independent suspension is independent of the left and right wheels, and the other side is generally the steering mechanism. No rear wheel drive, power transmission mechanism is present.

여기에 사용되는 스프링은 판 스프링과 코일 스프링과 토션바 스프링이며 구조상 차체 바닥을 낮게 할 수 있어 차 실내가 넓기 때문에 주로 승용차에 많이 사용되며, 또 좌우 바퀴가 독립적으로 움직이기 때문에 상호 간섭을 일으키지 않아 승차감이 좋은 장점이 있다.The springs used here are leaf springs, coil springs and torsion bar springs, and because the structure can lower the bottom of the car body, it is mainly used in passenger cars because the interior of the car is wide. Riding comfort is good.

상기와 같은 장점을 갖는 현가장치에 사용되는 스프링중 판 스프링은 도 1에서 도시되는 바와 같이 판 스프링(1)은 스프링강을 적당히 구부린 띠 모양으로 된 것을 몇 장 겹쳐서 그 중심에 센터 볼트(2)로 조인 것이다.The leaf spring of the spring used in the suspension device having the above-described advantages, as shown in Figure 1 the leaf spring (1) is overlapping a few sheets of a band-shaped moderately bent spring steel, the center bolt (2) in the center thereof To join.

여기서 가장 길이가 긴 주 스프링판의 양끝에는 스프링 아이(3)를 두고 섀클 핀(4)과 행거(5)를 통하여 차체 프레임(8)에 설치하고 상기 프레임(8)의 중앙부 하단에는 브라켓트(6)에 의해서 러버 스톱퍼(7)가 취부되어 구성된 것이다.The longest main spring plate has spring eyes 3 at both ends thereof and is installed on the vehicle body frame 8 through shackle pins 4 and hangers 5, and brackets 6 are provided at the lower end of the center of the frame 8; ), The rubber stopper 7 is mounted.

상기와 같은 구조로 이루어진 자동차의 리어 현가의 충격과 흡수를 보면은 지면으로부터 충격인 도 1에서의 가를 섀클 핀(4)이 나방향으로 운동을 하여 차체에 전달되는 충격을 감소시켜 주지만 충격을 흡수하는 힘이 약하여 승차감이 떨어지는 문제점이 있다.In the shock and absorption of the rear suspension of the vehicle having the above structure, the shackle pin 4 moves in the lateral direction from the ground in FIG. 1 to reduce the shock transmitted to the vehicle body, but absorbs the shock. There is a problem that the ride strength is low due to weak power.

본 고안은 상기와 같은 문제점을 해결하기 위해서 안출한 것으로서 프레임의 일측에 위치하여 판 스프링과 연결되는 섀클 핀을 댐퍼로 교체하여 구성함으로서 차체에 전달되는 충격을 감소함은 물론 승차감을 향상시키는 댐퍼를 장착한 리어 현가장치를 제공하는 것이다.The present invention has been devised to solve the above problems, and by replacing the shackle pin connected to the leaf spring on the side of the frame with a damper to reduce the shock transmitted to the vehicle body as well as to improve the ride comfort It is to provide a rear suspension mounted.

도 1은 일반적인 판 스프링이 취부된 현가장치를 개략적으로 나타낸 사시도.1 is a perspective view schematically showing a suspension mounted with a common leaf spring.

도 2는 본 고안의 구성을 나타낸 정면도.Figure 2 is a front view showing the configuration of the present invention.
