Description

공기배출이 가능한 차량 조향축의 유니버셜조인트 구조{UNIVERSAL JOINT STRUCTURE OF AUTOMOTIVE VEHICLE STEERING SHAFT TO BE POSSIBLE DEFLATION OF AIR}Universal joint structure of vehicle steering shaft that can discharge air {UNIVERSAL JOINT STRUCTURE OF AUTOMOTIVE VEHICLE STEERING SHAFT TO BE POSSIBLE DEFLATION OF AIR}

본 발명은 공기배출이 가능한 차량 조향축의 유니버셜조인트 구조에 대한 것으로서, 특히 슬립이동시 발생되는 압축공기를 배출하여 지속적으로 기밀을 유지할 수 있도록 된 공기배출이 가능한 차량 조향축의 유니버셜조인트 구조에 관한 것이다.The present invention relates to a universal joint structure of a vehicle steering shaft capable of discharging air, and more particularly, to a universal joint structure of a vehicle steering shaft capable of discharging air to keep airtight by discharging compressed air generated during slip movement.

일반적으로 유니버셜 조인트라 하면 자동차등에서 볼 수 있는 바와 같이 동력을 발생시키는 원동기구로부터 일정거리를 두고 떨어져 있는 종동기구로 동력을 전달하되, 상기 원동축과 상기 종동축이 상호 수직으로 교차하지도 않고, 서로 나란하지도 않은 상태일 때 사용하는 동력 전달 기구로써, 이 경우 원동축 또는 종동축 중 어느 한쪽의 축에는 차체에 작용하는 충격을 흡수하는 한편, 조립성을 향상시키기 위하여 그 길이가 수시로 보상될 수 있도록 중앙부위에 주행시 노면의 충격에서 들어오는 킥-백(Kick-Back) 하중을 흡수할 수 있도록 하고, 또한 칼럼과 조향 기어박스를 조립할 때, 축방향으로 습동될 수 있도록 하므로서 조립이 편리하도록 슬립구조로 결합되어지게 된다.Generally, the universal joint transmits power to a driven mechanism that is spaced apart from a driving mechanism that generates power, as seen in automobiles, but the driving shaft and the driven shaft do not vertically cross each other, It is a power transmission mechanism used when it is not in a side-by-side state, in which case one of the shaft or the driven shaft absorbs the shock acting on the vehicle body, and its length can be compensated from time to time in order to improve assemblability. The slip structure is designed to absorb the kick-back load from the impact of the road surface when driving in the center area, and to slide in the axial direction when assembling the column and the steering gearbox. To be combined.

그리고, 도1에 도시된 바와같이 상기와 같은 슬립구조의 양끝부위에는 조향핸들쪽으로 연결되는 인너샤프트를 삽입할 수 있는 파이프(1)와, 이 파이프(1)를 통해 조향력이 전달되는 샤프트(2)가 조인트를 매개로 결합되되, 이 조인트는 상기 파이프(1)의 끝단에 결합된 아웃조인트(1a)와, 샤프트(2)의 끝단에 결합된 인너조인트(2a)로 이루어져 서로 결합되어진다.And, as shown in Figure 1, both ends of the slip structure as described above pipe (1) that can be inserted into the inner shaft connected to the steering wheel, and the shaft 2 through which the steering force is transmitted through the pipe (1) ) Is coupled via a joint, which is composed of an out joint (1a) coupled to the end of the pipe (1), and an inner joint (2a) coupled to the end of the shaft (2).

여기서, 상기 샤프트(2)의 접촉단(2b)과 근접되는 파이프(1)의 끝단에는 그 내부로 빗물과 같은 유체의 유입을 방지하기 위해 고무와 같은 패킹부재(3)가 끼워지게 된다.Here, the packing member 3, such as rubber, is fitted at the end of the pipe 1 close to the contact end 2b of the shaft 2 to prevent the inflow of fluid such as rainwater.

그러나, 이와같이 조향정도에 따라 파이프(1)내에 삽입된 인너샤프트가 이동되는 슬립구조에 따라 파이프(1)내의 공기가 압축되어지고, 이로인해 패킹부재(3)가 밀려져 이탈되는 현상이 있게된다.However, the air in the pipe 1 is compressed according to the slip structure in which the inner shaft inserted in the pipe 1 is moved according to the degree of steering, thereby causing the packing member 3 to be pushed out and separated. .

이러한 패킹부재(3)의 이탈현상이 조인트(1a,2a)를 매개로 결합된 샤프트(2)의 접촉단(2b)부위에 의해 어느정도 방지되지만, 상기 샤프트(2)의 접촉단(2b)이 계속적으로 움직이게 되는 작동 특성상 시간 경과에 따라 지속적으로 가해지는 공기의 압축력에 의해 패킹부재(3)가 이탈되어 파이프(1)의 내부로 빗물등과 같은 유체가 유입되는 문제가 발생되어지는 문제가 있게 된다.This separation of the packing member 3 is somewhat prevented by the contact end 2b of the shaft 2 coupled via the joints 1a and 2a, but the contact end 2b of the shaft 2 is prevented. Due to the characteristics of the operation continuously moving, the packing member 3 is separated by the compressive force of air continuously applied over time, causing a problem that a fluid such as rainwater flows into the inside of the pipe 1. do.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 발명한 것으로서, 파이프내의 공기의 압축 압력이 어느정도 이상 상승되면 즉시 외부로 배출시켜 공기의 압축력이 패킹부재를 가압하지 않도록 된 것이다.Therefore, the present invention has been invented to solve the above-mentioned problems in view of the conventional problems, and when the compression pressure of air in the pipe is raised to a certain degree or more, it is immediately discharged to the outside so that the compression force of the air does not pressurize the packing member.

이를 위한 특징적인 실시 수단은 파이프의 끝단에 끼워진 패킹부재가 에어홀을 형성함과 더불어 이 에어홀부위를 샤프트의 접촉단이 지지하도록 된 것이다.A characteristic means for this is that the packing member fitted to the end of the pipe forms an air hole and the air hole is supported by the contact end of the shaft.

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 공기배출이 가능한 차량 조향축의 유니버셜조인트 부분 구조도를 도시한 것인바, 본 발명은 종래와 같이 인너·아웃조인트(1a,2a)를 매개로 조향핸들쪽으로 연결되는 인너샤프트를 삽입할 수 있는 파이프(1)와 샤프트(2)가 결합됨과 더불어, 상기 샤프트(2)의 접촉단(2b)과 근접되는 파이프(1)의 끝단에 고무와 같은 패킹부재(3)가 끼워지게 된다.Figure 2 shows a structural diagram of the universal joint of the vehicle steering shaft capable of discharging the air of the present invention, the present invention inserts the inner shaft connected to the steering wheel via the inner and outer joints (1a, 2a) as in the prior art The pipe 1 and the shaft 2 may be coupled together, and the packing member 3, such as rubber, may be fitted to the end of the pipe 1 adjacent to the contact end 2b of the shaft 2. .

여기서, 상기 패킹부재(3)는 한쪽 측면의 중앙부위에 돌출되게 형성된 돌출부(3a)와 , 이 돌출부(3a)부위를 통해 관통된 에어홀(3b)이 형성되는 한편, 상기 패킹부재(3)의 돌출부(3a)를 수용하여 안착될 수 있도록 샤프트(2)의 접촉단(2b)에 함몰된 안착홈(2b')이 형성되어 진다.Here, the packing member 3 is formed with a protrusion 3a protruding from a central portion of one side, and an air hole 3b penetrated through the protrusion 3a, while the packing member 3 is formed. A recess 2b 'recessed in the contact end 2b of the shaft 2 is formed so as to receive the protrusion 3a of the shaft 2.

이에따라, 조향정도에 의해 파이프(1)내에 삽입된 인너샤프트가 파이프(1)의 패킹부재(3)쪽으로 이동되고, 이에따라 인너샤프트가 파이프(1)내의 공기를 압축하게 되지만, 압축되는 공기의 압력이 어느정도 이상이 되면 즉, 패킹부재(3)의 에어홀(3b)을 통해 빠져나가는 정도의 압력이상이 되면 파이프(1)내의 공기가 자연적으로 외부로 배출되어져 패킹부재(3)를 가압하지 않게 된다.Accordingly, the inner shaft inserted into the pipe 1 is moved toward the packing member 3 of the pipe 1 by the degree of steering, so that the inner shaft compresses the air in the pipe 1, but the pressure of the compressed air If this is more than a certain degree, that is, if the pressure is greater than the pressure to escape through the air hole (3b) of the packing member 3, the air in the pipe (1) is naturally discharged to the outside so as not to pressurize the packing member (3) do.

또한, 상기 패킹부재(3)의 돌출단(3a)을 수용한 샤프트(2)의 안착홈(2b')에 의해 샤프트(2)의 접촉단(2b)이 계속적으로 움직이더라도 패킹부재(3)의 이탈현상이 방지되어짐은 물론이다.Further, even if the contact end 2b of the shaft 2 is continuously moved by the seating groove 2b 'of the shaft 2 accommodating the protruding end 3a of the packing member 3, the packing member 3 Of course, this phenomenon is prevented.

이상 상세히 설명한 바와 같은 본 발명은 파이프의 끝단에 끼워진 패킹부재가 에어홀을 형성함과 더불어 이 에어홀부위를 샤프트의 접촉단이 지지하여, 파이프내의 공기의 압축 압력이 어느정도 이상 상승되면 즉시 외부로 배출시켜 공기의 압축력이 패킹부재를 가압하지 않게 되므로 패킹부재의 이탈현상을 방지하게 되는 효과가 있게 된다.According to the present invention as described in detail above, the packing member fitted to the end of the pipe forms an air hole, and the air hole is supported by the contact end of the shaft, and when the compression pressure of the air in the pipe is raised to a certain degree, Since the compression force of the air does not pressurize the packing member by discharging, there is an effect of preventing the separation of the packing member.
