Abstract

PURPOSE: A bumper device of a vehicle is provided to buffer a shock transferred to a vehicle body and an occupant by absorbing the shock upon a collision of a vehicle. CONSTITUTION: A pair of slots are formed on a front face of a cross frame(22) and a vertical rod(28) of a mobile support body(26) is penetrated through the slots. A roller(32) is arranged on upper and lower faces of the cross frame. When a plate spring(24) is curved by a load, the mobile support body moves from the slot and buffers a shock. A bumper(38) is fixed by a bolt between bumper brackets(36) in the center of the front face of the plate spring. A rubber bundle(40) fixes on the cross frame on a rear lower part. When the spring plate is pushed, the rubber bundle acts as a damper. Thereby, the shock given to the bumper is absorbed while the spring plate is curved and collided on the rubber bundle.

Description

자동차의 완충장치{Shock absorber for automobile}Shock absorber for automobile

본 발명은 자동차의 완충장치에 관한 것으로서, 더욱 상세하게는 자동차의 추돌 또는 충돌시 충격을 2중으로 완화시켜 차체 및 승객의 안전성을 확보할 수 있는 자동차의 완충장치에 관한 것이다.The present invention relates to a shock absorber of a vehicle, and more particularly, to a shock absorber of a vehicle that can ensure the safety of the vehicle body and passengers by mitigating the impact in the event of a collision or collision of the vehicle to double.

자동차는 엔진에서 폭발성이 있는 연료를 연소시킬 때 발생되는 동력을 회전력으로 변화시켜서 휠로 전달하여 지상에서 거리변화를 추구하는 이동수단으로서, 이동시에는 조향장치를 이용하여 진행방향을 조절하게 된다.A vehicle is a moving means that changes the power generated when burning explosive fuel in an engine to a rotational force and transfers it to a wheel to pursue a distance change on the ground, and when moving, the driving direction is controlled by using a steering device.

이와 같은 자동차는 다른 자동차와의 추돌이나 충돌시 차체를 보호하고 승객의 안전성을 확보하기 위해서 자동차의 전면과 후면에 완충수단으로써 범퍼가 설치되어 있다.Such a vehicle is provided with a bumper as a shock absorbing means on the front and rear of the vehicle in order to protect the vehicle body in the event of a collision or collision with another vehicle and to ensure the safety of the passengers.

특히, 도 1에서는 종래 자동차, 특히 트럭 등과 같은 상용차의 완충수단인 범퍼를 보여주고 있다.In particular, Figure 1 shows a bumper as a shock absorbing means of a commercial vehicle, such as a conventional vehicle, in particular trucks.

차체의 골격을 형성하는 복수의 메인 프레임(2) 끝에는 크로스 프레임(4)이 가로 질러 배치되고, 이 크로스 프레임(4)에는 2개의 범퍼 스테이(6)가 세워진다.A cross frame 4 is disposed across the ends of the plurality of main frames 2 forming the skeleton of the vehicle body, and two bumper stays 6 are placed on the cross frame 4.

상기 범퍼 스테이(6)의 끝에 범퍼(8)가 설치되는 구조인데, 이 범퍼(8)에는 범퍼 브라켓(10)이 장착되어서 범퍼 스테이(6)의 끝과 체결되어지는 것이다.A bumper 8 is installed at the end of the bumper stay 6, and the bumper 8 is mounted to the bumper bracket 10 so as to be engaged with the end of the bumper stay 6.

이러한 구조로 이루어진 완충수단은 자동차의 추돌이나 충돌시 완충기능이 미약하여 범퍼가 크게 파손될 뿐만 아니라 그 충격이 차체와 승객에게 그대로 전달되어 2차 손상의 원인이 되고 있다.The shock absorbing means having such a structure has a weak shock absorbing function in the event of a collision or collision of a vehicle, which not only significantly damages the bumper, but also transmits the shock to the vehicle body and the passenger as it causes secondary damage.

상술한 문제점을 해결하기 위해 안출된 본 발명은 자동차의 추돌이나 충돌시 그 충격을 흡수하여 차체와 승객으로 전달되는 충격을 완화시킬 수 있는 자동차의 완충장치를 제공하는 것이 목적이다.The present invention devised to solve the above problems is an object of the present invention to provide a shock absorber of a vehicle that can absorb the impact during the collision or collision of the vehicle to mitigate the shock transmitted to the vehicle body and the passenger.

이러한 목적을 달성하기 위한 본 발명의 완충장치는 자동차의 전후면에 설치되는 크로스 프레임과, 이 크로스 프레임에 양단이 지지되어지는 판 스프링과, 판 스프링에 고정되어지는 범퍼로 구성된다.The shock absorber of the present invention for achieving the above object is composed of a cross frame provided on the front and rear surfaces of the vehicle, a leaf spring supported at both ends of the cross frame, and a bumper fixed to the leaf spring.

그리고, 판 스프링의 중간에 해당하는 크로스 프레임에는 러버 뭉치가 장착되어 판 스프링이 휠 때 충격을 완화시킬 수 있다.In addition, the rubber frame is mounted on the cross frame corresponding to the middle of the leaf spring, thereby alleviating the impact when the leaf spring is bent.

또한, 크로스 프레임에 다수의 슬롯을 형성하고 판 스프링의 양단에 고정됨과 동시에 다수의 슬롯상에서 이동 가능한 이동 지지체가 설치될 수도 있다.In addition, a plurality of slots may be formed in the cross frame and fixed to both ends of the leaf springs, and a movable support movable on the plurality of slots may be provided.

이에 따라, 상용차의 추돌이나 충돌시 판 스프링에서 1차로 충격을 흡수하고 2차로 러버 뭉치에서 충격을 흡수하는 효과를 얻을 수 있다.Accordingly, it is possible to obtain the effect of absorbing the shock firstly in the leaf spring during the collision or collision of the commercial vehicle and the impact in the rubber bundle secondly.

이하, 본 발명에 따른 바람직한 구현예를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에서는 본 발명에 따른 자동차의 완충장치를 평면도로 나타내고 있다.2 shows a shock absorber of a vehicle according to the present invention in a plan view.

도면 부호 20은 차체의 메인 프레임이다.Reference numeral 20 is a main frame of the vehicle body.

메인 프레임(20)의 끝에는 그 단면이 대략 I자 형상인 크로스 프레임(22)이 가로 질러 설치되고, 이 크로스 프레임(22)의 전면에는 활 모양으로 생긴 판 스프링(24)이 지지되어 진다.At the end of the main frame 20, a cross frame 22 having a substantially I-shaped cross section is provided across it, and a leaf spring 24 shaped like a bow is supported on the front of the cross frame 22.

특히, 판 스프링(24)의 양끝에는 이동 지지체(26)가 결합되어지는데, 이 이동 지지체(26)는 2개의 종렬 로드(28)에 2개의 횡렬 로드(30)가 가로 질러 용접되어지며, 각각의 횡렬 로드(30)에는 롤러(32)가 설치된다.In particular, the moving support 26 is coupled to both ends of the leaf spring 24, which is welded across two row rods 30 to two column rods 28, respectively. The roller 32 is installed in the horizontal rod 30 of the.

그리고, 종렬 로드(28)의 끝에는 샤프트(34)가 설치되는데, 샤프트(34)의 양끝에는 너트가 체결되어지며, 이 샤프트(34)에는 판 스프링(24)의 양단이 일부 감겨진 상태로 일체화된다.A shaft 34 is installed at the end of the column rod 28, and nuts are fastened to both ends of the shaft 34, and both ends of the leaf spring 24 are integrally wound on the shaft 34. do.

한편, 크로스 프레임(22)의 전면에는 다수의 슬롯이 한 쌍을 이루어 형성되어 있고, 이 한 쌍의 슬롯으로 이동 지지체(26)의 종렬 로드(28)가 관통되어서 크로스 프레임(22)의 상하면으로 롤러(32)가 배열되는 구조로 되어서 판 스프링(24)이 하중을 받아서 휠 때 이동 지지체(26)가 슬롯에서 이동하여 충격을 완화시킨다.On the other hand, a plurality of slots are formed in a pair on the front surface of the cross frame 22, and the pair of slots penetrate the column rod 28 of the moving support 26 to the upper and lower surfaces of the cross frame 22. The roller 32 is arranged so that when the leaf spring 24 is subjected to a load, the movable support 26 moves in the slot to mitigate the impact.

판 스프링(24)의 전면 중간에는 범퍼 브라켓(36)을 사이에 두고 볼트에 의해 범퍼(38)가 고정되며, 후면 하방에는 러버 뭉치(40)가 크로스 프레임(22)에 고정되어져서 판 스프링(24)이 밀려 내려질 때 댐퍼로써 작용한다.In the middle of the front of the leaf spring 24, the bumper 38 is fixed by a bolt with a bumper bracket 36 interposed therebetween, and a bundle of rubbers 40 is fixed to the cross frame 22 at the rear and bottom of the leaf spring 24. It acts as a damper when 24) is pushed down.

상술한 바와 같은 구조로 된 완충장치는 자동차가 추돌하거나 충돌하면, 범퍼(38)로 가해지는 충격은 1차로 판 스프링(24)이 휘면서 흡수하고 2차로 판 스프링(24)이 러버 뭉치(40)에 충돌하면서 완화시키게 된다.When the shock absorber having the structure as described above collides or collides with the vehicle, the shock applied to the bumper 38 is primarily absorbed while the leaf spring 24 is bent, and the leaf spring 24 is secondly provided with a rubber bundle 40. To alleviate).

이때, 이동 지지체(26)는 판 스프링(24)이 휠 때 그 하중을 받아 슬롯상에서 이동하게 되는 것이다.At this time, the moving support 26 is to move on the slot under the load when the leaf spring 24 is wheeled.

이상에서 살펴본 바와 같이 본 발명에 따른 구현예는 종래의 문제점을 실질적으로 해소하고 있다.As described above, the embodiment of the present invention substantially solves the conventional problems.

즉, 범퍼와 크로스 프레임의 사이에 활 모양으로 생긴 판 스프링을 설치하고 판 스프링의 하방에는 러버 뭉치가 크로스 프레임에 설치됨으로써, 판 스프링이 하중을 받아 휠 때 댐퍼로 작용한다.That is, by installing a bow-shaped leaf spring between the bumper and the cross frame, and a bundle of rubber is installed in the cross frame below the leaf spring, the leaf spring acts as a damper when the leaf spring is loaded under load.

따라서, 자동차가 추돌이나 충돌하여 범퍼로 충격이 가해지면, 1차로 판 스프링이 그 충격을 흡수하고 이어서 2차로 러버 뭉치에서 충격을 흡수하여 차체의 손상과 승객의 안전성을 확보할 수 있게 된다.Therefore, when the vehicle is collided or collided and the impact is applied to the bumper, the leaf spring primarily absorbs the impact, and then secondarily absorbs the impact from the rubber bundle, thereby ensuring damage to the vehicle body and passenger safety.
