본 고안은 차량용중간조향샤프트의 방진구조에 관한 것이다.The present invention relates to a dustproof structure of an intermediate steering shaft for a vehicle.

자동차등의 차량의 조향축구조에는 중간조향축(Intermediate Steering Shaft)이 개재되어 연결구조를 구성하게 된다.The steering shaft structure of a vehicle such as an automobile is interposed with an intermediate steering shaft to form a connection structure.

상기와 같은 중간조향축은 그 연결선상에서 방진 및 빵음구조를 구비하는 것이 통상적인 기술로서 이러한 구성의 종래의 차량용 중간조향샤프트의 방진구조가 제 1 도 내지 2 도에 개시되어 있다.The intermediate steering shaft as described above has a dustproof and a banging structure on its connection line, and a dustproof structure of a conventional vehicle intermediate steering shaft of such a configuration is disclosed in FIGS. 1 to 2.

제 1 도에서 노면으로부터의 진동이 토오션요우크(1)로까지 전달되므로, 대소경의 한쌍의 스틸튜브(2) 사이에 고무부싱(3)을 압입하고 이 고무부싱(3)의 내측스틸튜브(2-1)에 중간조향축(4)을 끼움으로써 고무부싱(3)에 의하여 이러한 진동의 전달이 감쇄되게 하거나 제 2 도에서와 같이 각각 분리된 토오션요우크(1)의 단턱(11)에 끼움되는 스틸튜브(5)내에 고무부싱(3)을 압입하는 구조를 가진다.In FIG. 1, since the vibration from the road surface is transmitted to the torsion yoke 1, the rubber bushing 3 is press-fitted between the pair of steel tubes 2 of a small diameter, and the inner steel tube of the rubber bushing 3 is pressed. By inserting the intermediate steering shaft 4 in (2-1), the transmission of these vibrations is attenuated by the rubber bushing 3, or the step 11 of the torsion yoke 1 separately separated as shown in FIG. ), The rubber bushing 3 is press-fitted into the steel tube 5 to be fitted.

이러한 스틸튜브(2)를 사용하는 근본적인 이유는 전체적으로 강성을 주고 고르게 진동이 감쇄되게 하는 것이 목적이다.The basic reason for using this steel tube 2 is to give rigidity as a whole and to evenly damp vibrations.

상기와 같은 종래의 구성은 스틸튜브의 가공과 압입에 다대한 노력이 들고 스틸튜브에 의하여 감소가 효과적으로 이루어지지 아니한다는 문제점이 발생되며 제 2 도의 구성은 결합부의 강성이 보장되지 아니한다는 결점을 가진다.The conventional configuration as described above has a problem in that it takes a lot of effort to process and press-fit the steel tube and the reduction is not effectively made by the steel tube, and the configuration of FIG. 2 has the drawback that the rigidity of the joint is not guaranteed. .

이상과 같은 종래의 문제점을 일소하는 것을 본 고안의 차량용중간조향샤프트의 방진구조의 목적으로 한다.The purpose of the dust-proof structure of the vehicle intermediate steering shaft of the present invention is to eliminate the above conventional problems.

이하의 부수된 제 3 도와 함께 본 고안의 차량용중간조향샤프트의 방진구조를 더욱 상세하게 설명한다.The dustproof structure of the vehicle intermediate steering shaft of the present invention together with the accompanying third degree will be described in more detail.

통상적인 토우션요우크(20)는 내부로 함입되어 중공체를 만드는 고무부싱파지공(21)을 가지고 이 중간부싱파지공(21)내에는 소정의 강성을 가지는 고무부싱(23)이 삽입되고 고무부싱(23)의 내경부(24)에 중간조향축(25)이 삽입되어 조립이 완성된다.The conventional torsion yoke 20 has a rubber bushing gripping hole 21 which is embedded into the hollow bushing hole 21 and a rubber bushing 23 having a predetermined rigidity is inserted into the intermediate bushing gripping hole 21. The intermediate steering shaft 25 is inserted into the inner diameter portion 24 of the rubber bushing 23 to complete the assembly.

상기 고무부싱(23)은 개략 링형상의 중공 내경부를 가지는 실린더체이다.The said rubber bushing 23 is a cylinder body which has a rough ring-shaped hollow inner diameter part.

이때에 바람직하기로는 고무부싱(23)의 내경부(24)는 가황처리등의 방법으로 경화시킨다. 이 경화되는 내경부(24)의 경화면은 제 1 도의 스틸튜브(2)와 같이 진동이나 측방모멘트를 고루 분산시키는 역할을 수행한다.At this time, preferably, the inner diameter part 24 of the rubber bushing 23 is hardened by methods, such as a vulcanization process. The hardened surface of the inner diameter portion 24 to be hardened serves to evenly distribute vibration or lateral moment like the steel tube 2 of FIG.

이상과 같은 본 고안의 차량용중간조향샤프트의 방진구조는 별도의 부재없이 단일의 구성으로서 중간조향축을 용이하게 토오션요우크에 연결시킬 수 있고 방진, 방음이 양호하고 원가의 절감에 유용한 고안인 것이다.As described above, the anti-vibration structure of the vehicle intermediate steering shaft of the present invention can be easily connected to the torsion yoke as a single configuration without a separate member, and is a useful design for reducing vibration and sound insulation and reducing cost. .
