Description
본 고안은 자동차의 동력전달장치에 관한 것이며, 특히는 유니버설 조인트를 드라이브 샤프트에 결합하기 위한 체결장치에 관한 것이다.The present invention relates to a power transmission device of an automobile, and more particularly to a fastening device for coupling a universal joint to the drive shaft.
자동차의 동력전달장치는 엔진에서 발생한 동력을 구동바퀴에 전달하기 위한 장치로서 엔진에서 발생한 동력을 클러치를 거쳐 변속기로 전달하고, 변속기에 적정회전수로 변속된 회전력을 추진축을 거쳐 액슬어셈블리를 통해 휠로 전달하도록 구성되어 있다.The power transmission device of a vehicle is a device for transmitting power generated from an engine to a driving wheel, and transmits power generated from the engine to a transmission via a clutch, and transmits a rotational force shifted to an appropriate rotational speed to a transmission through an axle assembly through a propulsion shaft. It is configured to deliver.
구동하는 휠에 따라 동력전달장치는 전륜구동형과 후륜구동형 및 4륜구동형등으로 구분되고 있다. 도 1에 전형적인 후륜구동형의 동력전달장치의 동력전달구조가 개략적으로 도시되어 있다.According to the driving wheel, the power transmission device is divided into front wheel drive type, rear wheel drive type and 4 wheel drive type. 1 schematically shows a power transmission structure of a typical rear wheel drive power transmission device.
도시된 바와 같이, 후륜구동형의 동력전달장치는 엔진(도시하지 않음)에서 발생한 동력을 변속기(2)에서 변속하여 추진축(3)을 거쳐 리어 휠(6)의 리어액슬 어셈블리(5)로 전달하여 리어 휠(6)을 구동하게 된다.As shown, the rear wheel drive type power transmission transmits power generated from an engine (not shown) in the transmission 2 and transmits it to the rear axle assembly 5 of the rear wheel 6 via the propulsion shaft 3. To drive the rear wheel 6.
따라서, 추진축(3)은 변속기(2)로부터 리어 액슬 어셈블리(5)로 회전력을 전달하는 축으로 추진축(3)의 설치각에 따른 진동을 수용하기 위해 등속 유니버설 조인트(4)로 연결된 구동축(3a)과 피동축(3b)으로 분할하여 구성된다.Accordingly, the propulsion shaft 3 is a shaft for transmitting rotational force from the transmission 2 to the rear axle assembly 5. The driving shaft 3a connected to the constant velocity universal joint 4 to receive vibrations according to the installation angle of the propulsion shaft 3. ) And the driven shaft 3b.
도 2에 종래의 추진축(3)과 유니버설 조인트(4)와의 결합구조가 되어 있다.In FIG. 2, the coupling structure of the conventional propulsion shaft 3 and the universal joint 4 is shown.
도시된 바와 같이, 종래의 추진축(3)과 유니버설 조인트(4)는 세레이션기어(7,8)를 이용하여 체결하는 방식이 일반적으로 사용되고 있다. 즉, 추진축(3)의 연결종단에 세레이션기어(7)를 형성하고, 유니버설 조인트(4)의 연결종단에는 세레이션홈(8)을 형성하여 유니버설 조인트(4)의 종단을 추진축(3)의 종단에 감합한 후 유니버설 조인트(4)의 길이방향으로 형성된 조임부(9)를 볼트와 너트로 조이므로써 체결이 이루어진다.As shown, the conventional propulsion shaft 3 and the universal joint 4 is generally used to fasten using the serration gear (7, 8). That is, the serration gear 7 is formed at the connection end of the propulsion shaft 3, and the serration groove 8 is formed at the connection end of the universal joint 4 to extend the end of the universal joint 4 to the propulsion shaft 3. After fitting to the end of the tightening by tightening the tightening portion 9 formed in the longitudinal direction of the universal joint (4) with bolts and nuts.
그러나, 이와 같은 종래 추진축(3)과 유니버설 조인트(4)의 결합구조는 추진축(3)과 유니버설 조인트(4)에 고가인 가공인 세레이션가공을 하여야 하며, 또한, 유니버설 죠인트(4)의 종단에는 조임부(9)를 형성하여야 하므로 구조가 복잡하여 제조비용을 상승시키는 원인이 되고 있다.However, such a coupling structure of the conventional propulsion shaft 3 and the universal joint 4 should be subjected to serration processing, which is an expensive process on the propulsion shaft 3 and the universal joint 4, and also ends of the universal joint 4. Since the tightening portion 9 must be formed in the structure, the structure is complicated, which causes the increase in manufacturing cost.
한편, 종래의 추진축(3)과 유니버설 조인트(4)의 체결구조는 세레이션부(7,8)를 감합한 후 볼트와 너트로 조임부(9)를 조여야 하므로 작업성을 나쁘게 하는 요인으로도 지적되고 있다.On the other hand, the conventional coupling structure of the propulsion shaft (3) and the universal joint (4) has to tighten the serration parts (7, 8), and then tighten the tightening part (9) with bolts and nuts as a factor that worsens workability. It is pointed out.
본 고안의 목적은 구조가 간단하여 염가로 제조할 수 있으며, 작업성도 우수한 추진축과 유니버설 조인트의 체결장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a fastening shaft and a universal joint fastening device having a simple structure and can be manufactured at a low cost.
