Description

차량 조향장치용 유니버셜 조인트의 충격에너지 흡수구조 {SHOCK ENERGY ABSORBING STRUCTURE OF UNIVERSAL JOINT FOR STEERING SYSTEM OF VEHICLE}Shock energy absorption structure of universal joint for vehicle steering system {SHOCK ENERGY ABSORBING STRUCTURE OF UNIVERSAL JOINT FOR STEERING SYSTEM OF VEHICLE}

본 발명은 차량 조향장치용 유니버셜 조인트의 충격에너지 흡수구조에 대한 것으로서, 특히 탄성력을 매개로 외부로부터 유입되는 진동을 흡수 할 수 있도록된 차량 조향장치용 유니버셜 조인트의 충격에너지 흡수구조에 관한 것이다.The present invention relates to an impact energy absorbing structure of a universal joint for a vehicle steering apparatus, and more particularly to an impact energy absorbing structure of a universal joint for a vehicle steering apparatus capable of absorbing vibrations introduced from the outside through an elastic force.

일반적으로 자동차의 조향장치에서는 조향축의 하단을 랙/피니언에 연결하되, 임의의 각도로 기울어진 채 연결하도록 되어 있기 때문에 유니버셜 조인트를 사용하게 된다.In general, a steering device of a vehicle uses a universal joint because the lower end of the steering shaft is connected to the rack / pinion, but is inclined at an arbitrary angle.

이때의 유니버셜 조인트는 그 길이 방향으로 충격이 발생하였을 경우, 그 충격이 운전자의 가슴에 위치하는 조향핸들에까지 전달되지 않도록 하기 위해 대부분 충격에너지 흡수장치를 설치하게 되는바, 이는 도 1에 도시된 바와같이 피니언 기어쪽에 연결되는 제1샤프트(1)와, 이 제1샤프트(1)에 결합되는 제2샤프트(2)로 구성되되, 이 샤프트(1,2)에는 브로우칭 가공방법으로 세레이션을 형성하여 길이 방향으로 슬라이딩되어 진다.In this case, when the impact occurs in the longitudinal direction of the universal joint, most of the impact energy absorbing device is installed so that the impact is not transmitted to the steering wheel located on the driver's chest, which is shown in FIG. The first shaft 1 is connected to the pinion gear and the second shaft 2 is coupled to the first shaft 1. The shafts 1 and 2 are serrated by a broaching method. It is formed to slide in the longitudinal direction.

그러나, 이와 같은 종래의 충격흡수장치는 제1샤프트(1)와 제2샤프트(2)의 내, 외경에 각각 형성된 세레이션부위를 매개로 외부에서 가해지는 충격이나 진동을 흡수하게 되므로 그 효과가 약할 뿐만 아니라 세레이션이 형성된 완충구간도 비교적 짧은 등 여러 가지 단점이 있게된다.However, such a conventional shock absorbing device absorbs the shock or vibration applied from the outside through the serrations formed in the inner and outer diameters of the first shaft 1 and the second shaft 2, respectively, so that the effect is effective. Not only is it weak, but the serration buffer section is relatively short, and there are various disadvantages.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 발명한 것으로서, 차량의 운행에 따라 외부로부터 가해지는 충격이나 진동을 완전하게 흡수하여 운전자에게 전달되지 않도록 된 것이다.Therefore, the present invention has been invented to solve the above-mentioned problems in view of the above-described conventional problems, and completely absorbs the shock or vibration applied from the outside according to the driving of the vehicle so as not to be transmitted to the driver.

이를 위한 특징적인 실시 수단은 제1·2샤프트사이에 흡수장치를 구비하되, 이 흡수장치는 제1·2샤프트에 결합된 스프링과 이들을 감싼 벨로우즈튜브로 구성된다.A characteristic implementation means for this is provided with an absorber between the first and second shafts, the absorber comprising a spring coupled to the first and second shafts and a bellows tube surrounding them.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 차량 조향장치용 유니버셜 조인트의 충격에너지 흡수구조의 부분도를 도시한 것인바, 피니언 기어쪽에 연결되는 제1샤프트(1)와 제2샤프트(2)가 탄성력을 매개로 충격과 진동을 흡수하는 흡수장치(3)로 결합되되, 이 흡수장치(3)는 제1·2샤프트(1,2)의 끝단에 고정된 스프링(3a)과, 이 스프링(3a)이 고정된 제1·2샤프트(1,2)의 끝부위에 고정되어 이들을 감싼 벨로우즈튜브(4)로 구성된다.Figure 2 shows a partial view of the impact energy absorbing structure of the universal joint for vehicle steering apparatus of the present invention, the first shaft 1 and the second shaft 2 connected to the pinion gear side impacts the elastic force through the medium Coupled to an absorber (3) which absorbs vibrations, and the absorber (3) has a spring (3a) fixed to the ends of the first and second shafts (1,2) and the spring (3a) It consists of a bellows tube 4 which is fixed to the ends of the first and second shafts 1 and 2 and wrapped them.

따라서, 외부에서 충격이 가해져 그 길이 방향으로 충격이 발생하게 되면 즉, 제1샤프트(1)의 길이 방향으로 가해진 힘이 스프링(3a)을 압축하게 되고, 이에따라 이 스프링(3a)에 고정된 제2샤프트(2)로 충격이 전달되지 않게됨은 물론, 상기 제1샤프트(1)로부터 진동이 가해지더라도 상기 스프링(3a)을 매개로 진동이 흡수되어 제2샤프트(2)로 전달되지 않게됨은 물론이다.Therefore, when the impact is applied from the outside and the impact occurs in the longitudinal direction, that is, the force applied in the longitudinal direction of the first shaft 1 compresses the spring 3a, and accordingly the first fixed to the spring 3a The shock is not transmitted to the second shaft 2, of course, even if vibration is applied from the first shaft 1, the vibration is absorbed through the spring 3a and is not transmitted to the second shaft 2. to be.

여기서, 상기 제1·2샤프트(1,2)의 끝부위에 고정되어 이들을 감싼 벨로우즈튜브(4)는 이물질의 침투를 방지함과 더불어, 제1·2샤프트(1,2)의 이동에 따라 압축되거나 인장되어져 제1샤프트(1)로부터 전달되는 진동을 어느정도 흡수하게 됨은 물론이다.Here, the bellows tube 4 fixed to the ends of the first and second shafts 1 and 2 to prevent them from infiltrating foreign matters and move in accordance with the movement of the first and second shafts 1 and 2. Of course, it is compressed or tensioned to absorb some vibration transmitted from the first shaft (1).

이상 상세히 설명한 바와 같은 본 발명은 제1·2샤프트사이에 탄성력을 갖춘 흡수장치를 구비하여 차량의 운행에 따라 외부로부터 가해지는 충격이나 진동을 완전하게 흡수하여 운전자에게 전달되지 않게 되는 효과가 있게 된다.The present invention as described in detail above is provided with an absorbing device having an elastic force between the first and second shafts to completely absorb the shock or vibration applied from the outside in accordance with the driving of the vehicle, thereby not being transmitted to the driver. .
