일반적으로, 프로펠러 샤프트는 변속기의 출력을 구동축에 전달하는 것으로, 변속기와 구동축 사이에 후륜구동 및 4륜 구동 승용차, 밴, 소형트럭과 같은 후륜구동 자동차의 동력을 전달하기 위해 사용된다.In general, the propeller shaft transmits the output of the transmission to the drive shaft, and is used to transfer the power of the rear wheel drive and rear wheel drive cars such as four-wheel drive passenger cars, vans, and small trucks between the transmission and the drive shaft.

이러한 프로펠러 샤프트는 자동차의 바닥에 장착되기 때문에, 외경이 100mm이하로 제작되며, 코트 전달 능력은 3,400Nm 이상이고, 외방향 최소 고유진동수는 6,500rpm 이상이다.Since the propeller shaft is mounted on the bottom of the vehicle, the outer diameter is made less than 100mm, the coat transmission capacity is more than 3,400Nm, the minimum minimum natural frequency is more than 6,500rpm.

도 1은 종래 자동차 프로펠러 샤프트를 도시한 도면이다.1 is a view showing a conventional vehicle propeller shaft.

도면에서 도시한 바와 같이, 프로펠러 샤프트(10)는 통공된 하이브리드 샤프 트(30) 양측으로 알루미늄 요크(20)를 삽입 연결한 후 상호 간의 연결 부위 외측에 용접(40)을 이용하여 연결하는 방식으로 조립을 이룰 수 있도록 구성되어 있다.As shown in the figure, the propeller shaft 10 is inserted into the aluminum yoke 20 to both sides of the hybrid shaft 30 through the insertion and then connected to each other using a weld 40 to the outside of the connection site It is configured to achieve assembly.

이러한 프로펠러 샤프트(10)는 변동하는 엔진의 회전력(토크)을 후륜축으로 전달하여 자동차가 이동하게 된다.The propeller shaft 10 transmits the rotating force (torque) of the fluctuating engine to the rear wheel shaft so that the vehicle moves.

그러나, 프로펠러 샤프트(10)는 구조가 단순하고, 가벼운 장점이 있지만, 하나의 샤프트로 구성됨에 따라 내구력이 높지 못한 문제점이 있다.However, the propeller shaft 10 has a simple structure and a light advantage, but there is a problem that the durability is not high as it is composed of one shaft.

이와 같이, 내구력이 높지 못할 경우, 전달되는 회전력이나 충격 등에 의해 형상의 변화가 발생됨에 따라 사고 발생 위험이 존재하는 문제점이 있다.As such, when the durability is not high, there is a problem that a risk of an accident occurs as a change in shape occurs due to the rotational force or the impact transmitted.

이에 따라, 엔진의 변동되는 회전력(토크)을 장기간 지속적으로 전달시킬 수 있는 프로펠러 샤프트(10)의 개발이 절실한 상황이다.Accordingly, the development of the propeller shaft 10 capable of continuously transmitting a variable rotational force (torque) of the engine for a long time is urgently needed.

이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로써, 알루미늄 샤프트와 복합재료 샤프트 및 고무층의 3중 구조로 프로펠러 샤프트를 제작하여 강도를 향상시킬 수 있다.Therefore, the present invention has been made to solve the above problems, it is possible to improve the strength by producing a propeller shaft in a triple structure of aluminum shaft, composite shaft and rubber layer.

그리고 복합재료 샤프트를 알루미늄 샤프트에 열융착 시킴에 따라 상호 견고하게 접합시킬 수 있어 강도를 향상시킬 수 있다.In addition, as the composite shaft is thermally fused to the aluminum shaft, the composite shaft can be firmly bonded to each other, thereby improving strength.

또한 고무층이 외부로부터 전달되는 충격을 효과적으로 완화시킬 수 있어 프로펠러 샤프트를 보호하여 수명을 연장시킬 수 있는 자동차 프로펠러 샤프트를 제공하는 것이 목적이다.It is also an object of the present invention to provide an automobile propeller shaft that can effectively mitigate the shock transmitted from the outside to protect the propeller shaft and extend its life.

상기 목적을 이루기 위한 본 발명은, 자동차의 동력을 전달하기 위해 트랜스미션과 뒷바퀴의 회전축을 연결시키는 알루미늄 샤프트, 상기 알루미늄 샤프트의 외측을 감싸도록 구비되고, 탄소섬유를 강화한 섬유강화 복합재료 샤프트, 및 상기 복합재료 샤프트의 외측을 감싸며, 복합재료 샤프트를 보호하는 고무층을 포함하여 이루어지고, 상기 복합재료 샤프트는 상기 알루미늄 샤프트의 외주면에 열융착 된다.The present invention for achieving the above object, the aluminum shaft for connecting the rotation axis of the transmission and the rear wheel for transmitting the power of the vehicle, provided to surround the outer side of the aluminum shaft, the fiber reinforced composite shaft reinforced carbon fiber, and the It includes a rubber layer surrounding the outer side of the composite shaft, and protects the composite shaft, the composite shaft is heat-sealed to the outer peripheral surface of the aluminum shaft.

또한, 상기 고무층의 두께는 상기 복합재료 샤프트의 두께와 동일하게 형성된다.In addition, the thickness of the rubber layer is formed to be the same as the thickness of the composite shaft.

상기한 바와 같이, 본 발명에 의한 자동차 프로펠러 샤프트에 의하면, 알루미늄 샤프트와 복합재료 샤프트 및 고무층에 의해 강도가 강화되어 전달 또는 가해지는 충격에 견딜 수 있어 형상을 유지할 수 있고, 특히, 고무층에 의해 외부 충격을 더욱 완화시킬 수 있어 장기 사용에도 엔진의 변동되는 회전력을 지속적으로 전달할 수 있어 자동차의 성능을 향상시킬 수 있게 하는 매우 유용하고 효과적인 발명이다.As described above, according to the automobile propeller shaft according to the present invention, the strength is enhanced by the aluminum shaft, the composite material shaft, and the rubber layer, so that it can withstand the shock transmitted or applied to maintain the shape, and in particular, the rubber layer It is a very useful and effective invention that can further alleviate the impact, and thus can continuously transmit the variable rotational force of the engine even in long-term use, thereby improving the performance of the car.

도면에서 도시한 바와 같이, 자동차 프로펠러 샤프트(100)는 알루미늄 샤프트(110)와 복합재료 샤프트(120) 및 고무층(130)으로 구성되며, 알루미늄 샤프트(110)는 내부가 통공된다.As shown in the figure, the vehicle propeller shaft 100 is composed of an aluminum shaft 110, a composite shaft 120 and a rubber layer 130, the aluminum shaft 110 is through the inside.

이 알루미늄 샤프트(110)는 자동차의 동력을 전달하기 위해 트랜스미션과 뒷 바퀴의 회전축을 연결시키게 된다.The aluminum shaft 110 connects the rotation shaft of the rear wheel with the transmission to transmit power of the vehicle.

그리고 복합재료 샤프트(120)는 알루미늄 샤프트(110)의 외측을 감싸도록 구비되는 것으로, 탄소섬유를 강화한 섬유강화 복합재료로 이루어진다.And the composite shaft 120 is provided to surround the outside of the aluminum shaft 110, made of a fiber reinforced composite material reinforced carbon fiber.

이러한 복합재료 샤프트(120)는 알루미늄 샤프트(110)에 열융착되는 것으로, 별도로 제작되어 알루미늄 샤프트(110)가 내측에 끼워진 후, 열에 의해 융착됨에 따라 견고하게 접합된다.The composite shaft 120 is thermally fused to the aluminum shaft 110, and is separately manufactured and then firmly bonded as the aluminum shaft 110 is fitted inside and then fused by heat.

고무층(130)은 복합재료 샤프트(120)의 외측을 감싸며, 복합재료 샤프트(120)를 보호하는 것으로, 외부로부터 전달되는 충격을 완화시켜 알루미늄 샤프트(110)와 복합재료 샤프트(120)의 형상이 변화되는 것을 방지하게 된다.The rubber layer 130 surrounds the outer side of the composite shaft 120 and protects the composite shaft 120. The rubber layer 130 mitigates the shock transmitted from the outside to form the aluminum shaft 110 and the composite shaft 120. To prevent changes.

이는, 엔진의 회전을 안정되고 지속적으로 전달함을 뜻하는 것으로, 프로펠러 샤프트(100)의 수명을 증가시킬 수 있게 된다.This means that the rotation of the engine is stably and continuously transmitted, and the life of the propeller shaft 100 can be increased.

이러한 고무층(130)의 두께는 복합재료 샤프트(120)의 두께와 동일하게 형성되는 것으로, 비포장 등의 오프로드(offroad)에서는 충돌되는 물체가 많기 때문에 그 두께를 더 두껍게 형성함이 바람직하다.The thickness of the rubber layer 130 is formed to be the same as the thickness of the composite shaft 120, the off-road (offroad), such as unpacking because there are many objects to collide, it is preferable to form a thicker thickness.
