본 발명은 차량의 구조물중에서 동력을 전달하는 구동축에 관한 것으로, 특히, 차량의 충돌시 발생하는 충격이 자체의 구조에 의하여 흡수되도록 하는 복합재료제 구동축의 이음매 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive shaft for transmitting power in a vehicle structure, and more particularly to a joint structure of a drive shaft made of a composite material that allows an impact generated during a collision of a vehicle to be absorbed by its structure.

자동차의 엔진에서 발생하는 구동력을 구름부재측으로 전달하기 위하여 통상적으로 크랭크축과 유니버어셜 죠인트를 사용한다.In order to transfer the driving force generated from the engine of the vehicle to the rolling member side, the crankshaft and universal joint are usually used.

이들의 구성은 금속재이며 상호 조립된 구성을 이루고 있어서, 차량의 충돌시에 발생하는 충격은 차량과 차량에 탑승한 자에게 그대로 전달되는 것이어서 인사사고가 발생하는 문제점이 있었다.Since these structures are made of metal and constitute a mutually assembled configuration, the impact generated when the vehicle collides is transmitted to the vehicle and the person who rides on the vehicle, which causes a problem of personnel accidents.

그러나, 상기의 구동축은 금속재와 상응하는 비금속재로 이루어진 구동부재와 상기 구동부재와 결합되어 동력의 전달과, 충격의 차단을 이루는 요크부재로 구동축의 이음매 구성을 갖추면 충격발생시에 구동축 자체에서 충격을 흡수하여 안전도를 지대하게 향상시키며, 인명보호의 효율이 극대화 될 것이어서 이러한 효과를 달성하고자 함을 본 발명의 목적으로 한다.However, the drive shaft is coupled to the drive member made of a non-metal material and a metal material and the yoke member which is coupled to the drive member to transfer power and block the impact, if the joint structure of the drive shaft is provided, the impact on the drive shaft itself when the impact occurs Absorption to greatly improve the safety, and the efficiency of life protection will be maximized to achieve this effect is an object of the present invention.

본 발명의 목적은 구동축을 요크부재와 비철금속재으로 이루어진 튜브부재를 구비하고 이 튜브부쟁를 말음형으로 하며 이 말음부에 요크를 결합되는 구성제공하는 것에 의하여 충족될 것이다.The object of the present invention will be met by providing a drive shaft having a yoke member and a tube member made of a non-ferrous metal material, making the tube striking convoluted and joining the yoke to the distal end.

이하 본 발명에 대한 실시예를 첨부도면과 함께 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with the accompanying drawings.

탄소섬유, 유리섬유등과 수지의 복합재료로 이루어지는 복합부재 튜브(1)를 마주보는 상태로 겹쳐서 설치하고, 이 튜브(1)의 선단에는 튜브의 선단직경 보다 큰 직경을 가지고, 중앙에 이음재(4)를 가진 요크(2)를 형성하여 상기 요크(2)의 접착단부(3)를 튜브(1)의 선단에 삽입하여 연결하는 구성을 이룬다.The composite member tube (1) made of carbon fiber, glass fiber, etc. and a composite material of resin is overlapped with each other. The tip of the tube (1) has a diameter larger than the tip diameter of the tube, A yoke 2 having 4) is formed to insert the adhesive end 3 of the yoke 2 into the tip of the tube 1 so as to connect the yoke 2.

상기의 튜브(1)와 요크(2)를 연결하는 과정에서 튜브(1)의 접착단부(3)측을 요크에 말아 붙이는 상태를 이룬다.In the process of connecting the tube 1 and the yoke 2, the adhesive end 3 side of the tube 1 is rolled up to the yoke.

상기와 같은 결합상태를 제1도로서 확인하면 튜브(1)와 요크(2)의 연결부분은 단턱진 상태를 이루게 되는데, 이러한 상태는 본 발명에서 매우 중요한 구성이다.When checking the coupling state as shown in FIG. 1, the connecting portion of the tube 1 and the yoke 2 forms a stepped state, which is a very important configuration in the present invention.

이러한 구성으로 이루어진 본 발명은 제1도의 상태로 차량에 설치한 상태에서 차량의 사고가 발생하는 경우 충격하중은 요크(2)가 튜브(1)를 향하여 이동하는 상태로 나타난다.According to the present invention having such a configuration, when the vehicle accident occurs in a state in which the vehicle is installed in the state of FIG. 1, the shock load appears as a state in which the yoke 2 moves toward the tube 1.

이러한 충격이 발생하면 요크(2)는 충격에 의하여 튜브(1)측으로 이동하는 상태가 된다. 요크가 튜브방향으로 이동하면 요크(2)의 단부직경이 튜브의 접착단부(3)보다 큰 직경을 이루고 있으므로 튜브(1)는 이때의 충격을 견디지 못하고 가상선과 같이 쪼개지는 상태를 이루게 된다.When such an impact occurs, the yoke 2 is moved to the tube 1 side by the impact. When the yoke moves in the tube direction, the end diameter of the yoke 2 has a diameter larger than that of the adhesive end 3 of the tube, so that the tube 1 does not withstand the impact at this time and breaks like an imaginary line.

이처럼 요크에 전달된 충격이 튜브로 전달되는 과정에서 요크(2)는 튜브측으로 삽입되면서 마찰이 발생하므로 이때의 마찰저항으로 충격이 튜브측으로 흡수되고, 또 튜브(1)는 요크(2)의 접착단부(3) 직경에 의하여 터지는 상태가 되므로 전달되는 충격은 튜브(1)의 쪼개지는 것에 의하여 흡수되어, 충격은 차체에 전달되지 못하고 소멸된다.As the shock transmitted to the yoke is transmitted to the tube, the yoke 2 is inserted into the tube and friction is generated, so the shock is absorbed to the tube by the frictional resistance at this time, and the tube 1 is bonded to the yoke 2. The impact delivered is absorbed by the splitting of the tube 1 because it is popped by the end 3 diameter, and the impact is not transmitted to the vehicle body and is extinguished.

이처럼 충돌충격이 튜브(1)의 쪼개지는 것에 의하여 소멸되면 차량의 보호는 물론, 탑승자도 상해를 입히지 않게 된다.In this way, when the impact shock is extinguished by the splitting of the tube 1, not only the vehicle but also the occupant are not injured.

이상에서와 같이 본 발명은 구동축의 구성을 비철금속으로 된 튜브를 겹쳐서 하나의 단위소재로 형성하고, 이에 튜브의 직경보다 직경을 갖는 단부를 구비한 요크를 형성하여 이들이 결합에 따라 동력의 전달과 충격의 전달을 이루며 특히 충격의 전달시에는 요크의 큰 직경을 가진 단부에 의하여 쪼개지는 상태로 충격이 소멸되어 차량의 보호는 물론 탑승자의 신체도 보호되는 것이다.As described above, the present invention forms the drive shaft as a unit material by superimposing a non-ferrous metal tube, thereby forming a yoke having an end portion having a diameter rather than the diameter of the tube, and transmitting and impacting power according to the combination thereof. In particular, when the shock is transmitted, the shock is extinguished in the state of being split by the end having the large diameter of the yoke, thereby protecting the vehicle as well as the occupant's body.
