Description

차량용 서스펜션에 취부되는 러버부쉬구조Rubber bush structure mounted on vehicle suspension

본 고안은 차량용 서스펜션에 취부되는 러버부쉬구조에 관한 것으로서 특히 진동에 의해서 발생되는 러버부쉬의 이탈을 방지하기 위해서 부쉬의 형상과 상기 부쉬를 감싸고 있는 커버의 형상을 변경함으로서 러버부쉬의 내구성을 향상시키고 제품의 품질을 향상시키는 차량용 서스펜션에 취부되는 러버부쉬구조에 관한 것이다The present invention relates to a rubber bush structure mounted on a vehicle suspension, and in particular, to prevent the rubber bush from being separated by vibration, by changing the shape of the bush and the shape of the cover surrounding the bush, the durability of the rubber bush is improved. It relates to a rubber bush structure mounted on a vehicle suspension for improving the quality of the product.

일반적으로 자동차의 현가장치는 차축과 차체를 연결하여 자동차의 주행중에 차축이 바퀴를 통하여 노면으로부터의 진동이나 충격을 끊임없이 받는다.In general, the suspension of the vehicle connects the axle and the body so that the axle is constantly subjected to vibration or shock from the road surface while the vehicle is running.

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 현가장치(Suspension System)라 한다.It is called a suspension system that connects the frame and the axle, including the shock absorber.

상기 현가장치는 구동 바퀴의 구동력, 제동시의 제동력 등을 프레임에 전달하고, 또 선회시 원심력을 이겨 차체의 균형을 이루는 역할도 하는 바, 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.

첫째, 노면으로부터 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.

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

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

여기서 사용되는 스프링은 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 coil springs and torsion bar springs, which can lower the bottom of the vehicle's structure. Therefore, they are mainly used in passenger cars because the interior of the car is wide, and the left and right wheels move independently. There is this.

상기와 같은 장점을 갖는 현가장치중 차량용 서스펜션구조는 프레임에 압축로드 및 으로어암을 조립한 후 프레임을 차체에 고정하도록 구성한다.Suspension structure for a vehicle of the suspension device having the above advantages is configured to assemble the compression rod and the lower arm to the frame and to fix the frame to the vehicle body.

즉 으로어암측에 연결된 타이어의 회전운동에 의하여 발생되는 진동을 압축로드의 일측에 취부되는 러버부쉬에서 흡수하도록 구성되어 있는 바, 도 1에서 도시되는 바와 같이 압압축로드(1)의 일측의 외면에 부시(2)가 취부되고 상기 부쉬(2)의 외면에는 러버(3)가 취부되며 러버(3)의 외측에는 커버(4)가 취부된 것이며 양측에는 스톱퍼(5)와 플레이트(6)가 취부되어 있다.That is, it is configured to absorb the vibration generated by the rotational movement of the tire connected to the lower arm side in the rubber bush mounted on one side of the compression rod, as shown in Figure 1 the outer surface of one side of the compression rod (1) The bush 2 is mounted on the outer surface of the bush 2, and the rubber 3 is mounted on the outer surface of the bush 2, and the cover 4 is mounted on the outside of the rubber 3, and the stopper 5 and the plate 6 on both sides thereof. It is attached.

상기와 같이 취부되는 종래의 차량용 서스펜션에 취부되는 러버부쉬는 타이어의 회전운동에 의해서 발생되는 진동 때문에 부시(2)와 러버(3)가 반복운동을 함으로서 압축로드(1)에서 이탈되는 문제점이 발생하여 상품성을 저하시키는 원인을 제공한다.The rubber bush mounted on the conventional vehicle suspension mounted as described above has a problem in that the bush 2 and the rubber 3 are separated from the compression rod 1 due to the repeated movement of the bush 2 due to the vibration generated by the rotational movement of the tire. To provide a cause of deterioration of the commerciality.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로 러버를 상호 감싸고 있는 커버의 내경과 부쉬의 외경의 형상을 오목하거나 블록한 형상으로 성형하여 구성함으로서 부쉬와 러버의 이탈을 방지함으로 제품의 내구성을 향상시키고 상품성을 향상시키는 차량용 서스펜션에 취부되는 러버부쉬구조를 제공하는 것이다.The present invention is designed to solve the above problems by forming a shape of the inner diameter of the cover surrounding the rubber and the outer diameter of the bush in a concave or block shape to prevent the departure of the bush and rubber to prevent the durability of the product It is to provide a rubber bush structure that is mounted to the vehicle suspension to improve the quality and improve the productability.

이하, 첨부된 도면에 의거하여 본 고안의 기술적 구성을 상세히 설명하면 다음과같다.Hereinafter, the technical configuration of the present invention in detail based on the accompanying drawings.

먼저 본 고안은 도 2 에 도시되는 바와 같이 차량용 서스펜션에 취부되는 부쉬(10)의 외면(11)과 커버(30)의 내면(31)을 오목블록한 형상으로 형성하고 이에 알맞는 러버(20)를 취부함을 기술적 구성상의 기본 특징으로 한다.First, the present invention forms the outer surface 11 of the bush 10 and the inner surface 31 of the cover 30 which are mounted on the vehicle suspension in a concave block shape as shown in FIG. Mounting is a basic feature of the technical configuration.

상기와 같이 구성된 본 고안의 부시(10)의 내부에 결합되는 압축로드가 좌, 우로 움직임에 따라서 발생되는 운동의 방향에 의해서 부쉬(10)가 같은 방향으로 움직이게 된다.The bushing 10 is moved in the same direction by the direction of movement generated by the compression rod coupled to the inside of the bush 10 of the present invention configured as described above left, right.

이때, 커버(30)의 프레임에 고정되어 있고 상기 부시쉬10)의 외면(11)과 커버(30)의 내면(31)에 형성된 오목블록한 형상으로 형성됨으로서 부시(10)의 움직임에 의해서 러버(20)의 이탈을 방지할 수 있는 효과가 있다.At this time, it is fixed to the frame of the cover 30 and formed in a concave block shape formed on the outer surface 11 and the inner surface 31 of the cover 30, the rubber by the movement of the bush 10. There is an effect that can prevent the departure of (20).

그러므로 부쉬(10)과 취부되는 러버(20)의 이탈을 방지하고 제품의 내구성을 향상시키는 효과가 있다.Therefore, there is an effect of preventing the departure of the bush 10 and the rubber 20 to be mounted and improve the durability of the product.

이상과 같이 본 고안은 차량용 서스펜션의 러버부쉬가 타이어의 회전에 의해서 발생되는 진동을 흡수하도록 취부함으로서 내구성을 향상시켜 상품성이 향상되는 유용한 고안이다.As described above, the present invention is a useful design in which the rubber bush of the vehicle suspension is installed to absorb vibration generated by the rotation of the tire, thereby improving durability and improving the merchandise.
