Description
본 고안은 꺽임식 유니버설 조인트의 중간 샤프트에 관한 것으로서, 특히 차량의 충돌시 중간 샤프트가 쉽게 꺽여지면서 스티어링 휠의 밀림을 방지할 수 있도록 한 꺽임식 유니버설 조인트의 중간 샤프트에 관한 것이다.The present invention relates to an intermediate shaft of a folding universal joint, and more particularly to an intermediate shaft of a folding universal joint to prevent the steering wheel from being pushed while the intermediate shaft is easily bent in a vehicle collision.
일반적으로 차량의 조향장치에는 유니버설 조인트가 사용되고 있다.In general, a universal joint is used for a steering device of a vehicle.
유니버설 조인트의 전방 샤프트는 차량의 추진축에 연결되어 있고, 후방 샤프트는 스티어링 휠에 연결되어 있으며, 전후방 샤프트는 중간 샤프트에 의해 연결되어 있다.The front shaft of the universal joint is connected to the propulsion shaft of the vehicle, the rear shaft is connected to the steering wheel, and the front and rear shafts are connected by the intermediate shaft.
첨부한 도 1과 도 2는 종래의 유니버설 조인트에서 중간 샤프트를 나타내는 사시도이다.1 and 2 are perspective views showing an intermediate shaft in a conventional universal joint.
도 1은 종래의 일체식 중간 샤프트(30a)를 보여주고 있다.1 shows a conventional integral intermediate shaft 30a.
일체식 중간 샤프트(30a)는 일체형의 중공관으로 단일품으로 되어 있기 때문에 차량 충돌시 압축하중을 받을 수 없도록 되어 있다.Since the integrated intermediate shaft 30a is a single piece of hollow tube, the integrated intermediate shaft 30a cannot receive a compressive load during a vehicle crash.
즉, 위와 같은 일체식 중간 샤프트(30a)는 차량 충돌시 차량 앞부분의 엔진이나 섀시 등이 후방으로 밀릴 때, 추진축에 연결된 일체식 중간 샤프트(30a)가 이때의 압축하중을 흡수하지 못하고 그대로 밀리게 되고, 이에 따라 스티어링 휠도 밀리면서 운전자에게 심각한 상해를 입히는 문제가 있다.That is, the integrated intermediate shaft 30a as described above is pushed in such a way that the integrated intermediate shaft 30a connected to the propulsion shaft does not absorb the compression load at this time when the engine or the chassis of the front part of the vehicle is pushed backward. As a result, the steering wheel is also pushed, causing serious injury to the driver.
이러한 문제를 해결하기 위하여 중간 샤프트를 조립식으로 만들어 스티어링 휠의 밀림을 방지할 수 있도록 한 조립식 유니버설 조인트의 중간 샤프트가 제안된 바 있다.In order to solve this problem, an intermediate shaft of a prefabricated universal joint has been proposed in which the intermediate shaft is assembled to prevent the steering wheel from being pushed.
첨부한 도 2는 종래의 조립식 중간 샤프트(30b)를 보여주고 있다.The accompanying Figure 2 shows a conventional prefabricated intermediate shaft 30b.
즉, 한쪽은 봉 형태로 구성하고 다른 한쪽은 관 형태로 구성하여 이들을 삽입식으로 끼워져 조립한 조립식 중간 샤프트(30b)가 많이 적용되고 있다.That is, a prefabricated intermediate shaft 30b in which one is configured in the form of a rod and the other is configured in the form of a tube, and is assembled by inserting them into an insert type, has been applied.
이러한 조립식 중간 샤프트(30b)는 차량 충돌시 엔진이나 섀시 등이 후방으로 밀릴 때, 그 충격으로 봉이 관 안쪽으로 삽입되면서 샤프트 전체의 길이변화를 가져오게 함으로써, 압축하중을 어느 정도 흡수할 수 있도록 한 것이다.The prefabricated intermediate shaft 30b is adapted to absorb the compressive load to some extent by causing the rod to be inserted into the tube due to the impact when the engine or the chassis is pushed backward in a vehicle crash. will be.
그러나, 위와 같은 조립식 중간 샤프트(30b)의 경우에는 길이변화를 일으키면서 압축하중을 흡수하기 위해서는 삽입되는 길이에 상응하는 만큼 샤프트의 길이가 길어져야 하기 때문에 공간적인 제약을 많이 받는 단점이 있고, 완충 성능면에서도 큰 실효를 기대할 수 없는 단점이 있다.However, in the case of the prefabricated intermediate shaft 30b as described above, in order to absorb the compressive load while causing a change in length, the length of the shaft has to be increased by the length corresponding to the length to be inserted, which causes a lot of space limitations. In terms of performance, there is a disadvantage that can not expect a large effect.
따라서, 본 고안의 목적은 차량 충돌시 꺽임변형을 통해 압축하중을 흡수하여 스티어링 휠의 밀림을 방지할 수 있도록 한 꺽임식 유니버설 조인트의 중간 샤프트를 제공하는데 있다.Accordingly, an object of the present invention is to provide an intermediate shaft of a folding universal joint to absorb the compression load through the bending deformation during vehicle collision to prevent the steering wheel from sliding.
상기한 본 고안의 목적을 달성하기 위하여 차량의 추진축에 연결되는 전방 샤프트와, 스티어링 휠에 연결되는 후방 샤프트와, 전후방 샤프트를 연결하는 중간 샤프트를 포함하는 유니버설 조인트에서, 상기 전방 샤프트에 제1지지부재를 형성하고 상기 후방 샤프트에 제2지지부재를 형성하며 상기 제1지지부재와 제2지지부재 사이에 중공관을 연결한 구조로 중간 샤프트를 구성하는 한편, 상기 중공관의 중간 부위에는 잘록한 목 부분을 형성한 것을 특징으로 하는 꺽임식 유니버설 조인트의 중간 샤프트가 제공된다.In order to achieve the above object of the present invention, in the universal joint including a front shaft connected to the propulsion shaft of the vehicle, a rear shaft connected to the steering wheel, and an intermediate shaft connecting the front and rear shafts, the first support to the front shaft The intermediate shaft is formed by forming a member, forming a second support member on the rear shaft, and connecting a hollow tube between the first support member and the second support member, while having a narrow neck on an intermediate portion of the hollow tube. An intermediate shaft of a fold universal joint is characterized in that it forms a part.

이하, 첨부도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 고안에 따른 꺽임식 중간 샤프트를 보여주고 있다.Figure 3 shows a folding intermediate shaft according to the present invention.
본 고안의 중간 샤프트(30)는 전방 샤프트(10)에 결합되는 제1지지부재(31)와, 후방 샤프트(20)에 결합되는 제2지지부재(32)와, 상기 제1지지부재(31)와 제2지지부재(32)의 각 일단에 각각 연결 고정되는 중공관(33)으로 구성되어 있고, 상기 중공관(33)의 중간 부위에는 목 부분(34)이 형성되어 있다.The intermediate shaft 30 of the present invention includes a first support member 31 coupled to the front shaft 10, a second support member 32 coupled to the rear shaft 20, and the first support member 31. ) And a hollow tube 33 connected to and fixed to respective ends of the second support member 32, and a neck portion 34 is formed at an intermediate portion of the hollow tube 33.
상기와 같이 구성되는 본 고안에 따른 꺽임식 유니버설 조인트의 중간 샤프트의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the intermediate shaft of the folding universal joint according to the present invention configured as described above are as follows.
도 4는 차량 충돌 후 중간 샤프트(30)의 변형상태를 보여주고 있다.4 shows a deformed state of the intermediate shaft 30 after the vehicle crash.
차량 충돌시, 차량의 앞부분에 있는 엔진이나 섀시 등이 후방으로 밀리면서 전방 샤프트(10)를 밀게 되면, 이때의 가해지는 압축하중은 중간 샤프트(30)의 중공관(33)에 전해지게 되고, 계속해서 중공관(33)이 목 부분(34)을 이용하여 꺽이면서 대부분의 압축하중을 흡수하게 되므로 후방 샤프트(20)를 포함하는 스티어링 휠의 밀림을 방지할 수 있게 된다.When a vehicle or an engine or a chassis in front of the vehicle pushes the front shaft 10 while pushing backward, the compression load applied at this time is transmitted to the hollow tube 33 of the intermediate shaft 30. Subsequently, the hollow tube 33 is bent using the neck portion 34 to absorb most of the compression load, thereby preventing the steering wheel including the rear shaft 20 from being pushed.
이상에서와 같이 본 고안은 차량 충돌시 목 부분이 꺽여지면서 압축하중을 흡수할 수 있도록 한 중간 샤프트를 제공함으로써, 스티어링 휠의 밀림방지에 따른 운전자의 안전을 최대한 보호할 수 있는 장점이 있는 것이다.As described above, the present invention provides an intermediate shaft that absorbs the compressive load while bending the neck in the event of a vehicle crash, thereby protecting the driver's safety as much as possible by preventing steering of the steering wheel. .
