프로펠러 샤프트와 변속기의 연결장치{Device for connecting propeller shaft to transmission}Device for connecting propeller shaft to transmission

본 발명은 차량의 프로펠러 샤프트와 변속기의 연결장치에 관한 것으로, 특히 유니버설 조인트와 주름 커버를 사용해서 프로펠러 샤프트와 변속기 출력축을 연결하는 연결장치에 관한 것이다.The present invention relates to a connection device of a propeller shaft and a transmission of a vehicle, and more particularly, to a connection device connecting a propeller shaft and a transmission output shaft using a universal joint and a pleat cover.

종래 차량의 프로펠러 샤프트는 차량의 길이방향을 따라 연장되게 형성되어 엔진의 회전동력을 차동장치를 통해 차륜에 전달하는 역할을 한다.The propeller shaft of a conventional vehicle is formed to extend in the longitudinal direction of the vehicle, and serves to transmit the rotational power of the engine to the wheels through a differential device.

따라서 상기 프로펠러 샤프트는 변속기 출력축과 그 일단부가 일체로 회전되게 연결되는 데, 즉 도 1에 도시한 바와 같이 변속기(1)의 출력축에는 삼각발 형상의 브라켓(2)이 일체로 끼워져 회전되게 결합되고, 프로펠러 샤프트(3)의 대응하는 선단부에도 상기 삼각발 형상의 브라켓(2)이 일체로 끼워져 결합되며, 상기 2개의 브라켓(2,2) 사이에는 고무재로 된 원형의 커플링(4)이 개재되어 상기 브라켓들과 체결되게 된다.Therefore, the propeller shaft is connected to the transmission output shaft and one end thereof integrally rotated, that is, as shown in Figure 1, the output shaft of the transmission 1 is integrally fitted with a triangular-shaped bracket (2) is rotatably coupled The triangular bracket 2 is integrally fitted to the corresponding distal end of the propeller shaft 3, and a circular coupling 4 made of rubber is provided between the two brackets 2 and 2. Is interposed to be fastened to the brackets.

상기 커플링(4)은 변속기 출력축의 회전동력을 프로펠러 샤프트로 전달하는 역할을 하고, 이러한 동력전달 과정에 진동 및 충격을 흡수하는 역할을 한다.The coupling 4 serves to transmit the rotational power of the transmission output shaft to the propeller shaft, and absorbs vibration and shock in this power transmission process.

그런데 상기와 같은 종래의 커플링과 삼발이 형상의 브라켓을 사용한 프로펠러 샤프트와 변속기의 연결구조에서는 고가의 커플링 및 브라켓 등을 사용함에 따라 차량의 원가를 상승시킨다고 하는 결점이 있었다.However, in the connection structure of the propeller shaft and the transmission using the conventional coupling and the tricycle-shaped bracket, there is a drawback that the cost of the vehicle is increased by using the expensive coupling and the bracket.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 변속기 출력축의 회전동력을 프로펠러 샤프트에 원활하게 전달할 수 있고, 구조도 간단하여 차량의 원가를 저감시킬 수 있으며, 차량의 충돌사고 발생시에 충격흡수기능도 우수한 프로펠러 샤프트와 변속기의 연결장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised in view of the above circumstances, and it is possible to smoothly transmit the rotational power of the transmission output shaft to the propeller shaft, and the structure is simple to reduce the cost of the vehicle, and to absorb the shock in the event of a collision of the vehicle. Its purpose is to provide an excellent connection between the propeller shaft and the transmission.

상기와 같은 목적을 달성하기 위한 본 발명은, 변속기 출력축과 프로펠러 샤프트의 각 선단부에는 일체로 끼워져 결합된 요크와, 이 2개의 요크를 서로 일체로 회전되게 연결하는 스파이더를 구비하고 있다.The present invention for achieving the above object is provided with a yoke integrally fitted to each of the front end portions of the transmission output shaft and the propeller shaft, and a spider connecting the two yokes to rotate integrally with each other.

바람직하기로는 상기 프로펠러 샤프트와 변속기 출력축의 연결부위의 외주에는 주름관 형태의 충격흡수커버가 장착된 것을 특징으로 한다.Preferably, the outer periphery of the connection portion between the propeller shaft and the transmission output shaft is characterized in that the corrugated pipe-shaped shock absorbing cover is mounted.

상기 변속기 출력축에 결합된 요크의 외주에는 원형 플레이트가 끼워져 결합되고, 이 플레이트의 외주에 상기 충격흡수커버의 일단이 끼워져 밴드로 조립되고, 상기 충격흡수커버의 타단은 상기 프로펠러 샤프트의 외주에 끼워져서 밴드로 조립된 것을 특징으로 한다.A circular plate is fitted to the outer circumference of the yoke coupled to the transmission output shaft, one end of the shock absorbing cover is fitted to the outer circumference of the plate, and assembled into a band, and the other end of the shock absorbing cover is fitted to the outer circumference of the propeller shaft. It is characterized by being assembled into a band.

본 발명에 따른 프로펠러 샤프트와 변속기의 연결장치에 의하면, 변속기 출력축에 장착된 요크와 프로펠러 샤프트에 장착된 요크가 스파이더를 매개로 일체로 회전되게 연결되어, 연결구조가 간단해서 차량의 원가를 절감할 수 있고, 상기 요크와 스파이더로 연결된 외주에는 주름관 형상의 충격흡수커버가 설치되어 차량의 정면 충돌시에 충격에너지를 흡수해서 충돌 대응이 효과적이며, 또한 변속기 출력축의 요크의 외주에 장착된 원형 플레이트는 연결부위의 비틀림 방지와 강성을 증대시키는 효과가 있다. According to the connection device of the propeller shaft and the transmission according to the present invention, the yoke mounted on the transmission output shaft and the yoke mounted on the propeller shaft are connected to be integrally rotated through the spider, so that the connection structure is simple to reduce the cost of the vehicle. The outer circumference connected to the yoke and the spider is provided with a corrugated pipe-shaped shock absorbing cover to absorb the impact energy during the frontal collision of the vehicle, so that the collision response is effective, and the circular plate mounted on the outer circumference of the yoke of the transmission output shaft It is effective in preventing twisting of the connecting part and increasing rigidity.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings.

도 2에는 본 발명에 따른 연결장치의 분해 사시도가 도시되어 있고, 도 3에는 본 발명에 따른 연결장치로 변속기의 출력축과 프로펠러 샤프트가 연결된 상태의 단면도가 도시되어는 바, 즉 변속기(11)의 출력축에는 대체로 좌우 U자 형상을 이루는 요크(12a)가 일체로 끼워져 결합되고, 튜브 형상의 프로펠러 샤프트(13)의 선단부에도 상하 U자 형상의 요크(12b)가 일체로 회전되게 끼워져 결합되며, 상기 각 요크(12a,12b)는 십자형상을 이루는 알루미늄 재질의 스파이더(12c)를 매개로 서로 연결되어, 변속기 출력축의 회전동력이 요크와 스파이더를 통해 프로펠러 샤프트에 전달되게 된다.2 is an exploded perspective view of the connecting device according to the present invention, Figure 3 is a cross-sectional view of the output shaft and the propeller shaft of the transmission is connected to the connecting device according to the present invention, that is, of the transmission 11 The yoke 12a, which generally forms the left and right U-shapes, is integrally fitted to the output shaft, and the upper and lower U-shaped yokes 12b are integrally rotated and coupled to the distal end of the tubular propeller shaft 13, Each yoke 12a, 12b is connected to each other via a spider 12c made of cross-shaped aluminum, the rotational power of the transmission output shaft is transmitted to the propeller shaft through the yoke and the spider.

상기와 같이 변속기 출력축과 프로펠러 샤프트가 유니버설 조인트로 연결됨에 따라 구조가 간단해져 차량의 원가를 절감시킬 수 있다.As described above, the transmission output shaft and the propeller shaft are connected to the universal joint, thereby simplifying the structure, thereby reducing the cost of the vehicle.

또한 상기 변속기 출력축의 요크(12a)의 외주에는 확장된 플랜지를 가진 원 형 플레이트(14)가 끼워져 조립되어, 연결부에서의 강성을 증대시키는 역할을 하게 된다.In addition, a circular plate 14 having an extended flange is fitted to the outer circumference of the yoke 12a of the transmission output shaft to serve to increase rigidity at the connection portion.

그리고 도 3에서 단면도로 자세히 도시한 바와 같이 고강도 플라스틱 소재로 제작되는 주름관 형태의 충격흡수커버(15)는 상기 원형 플레이트(14)의 외주에 그 일단이 끼워져 스틸재질의 밴드(16)로 조립됨과 더불어 상기 충격흡수커버의 타단은 상기 프로펠러 샤프트의 외주에 끼워져서 상기 밴드(16)로 조립되게 된다.And the shock absorbing cover 15 of the corrugated pipe shape is made of a high-strength plastic material as shown in detail in the cross-sectional view in Figure 3 is fitted to the outer periphery of the circular plate 14 is assembled into a band 16 of steel material and In addition, the other end of the shock absorbing cover is fitted to the outer circumference of the propeller shaft is assembled to the band (16).

상기와 같이 프로펠러 샤프트와 변속기가 연결되는 부위에 고강도 플라스틱 재질의 커버가 설치됨에 따라 차량의 충돌사고 발생시에 충격이 전달되면, 상기 충격흡수커버가 충격을 적절히 흡수해서 저감시켜 충돌 대응 성능이 향상되며, 연결부위에서의 진동 및 충격을 적절히 흡수해서 저감시켜 차량의 NVH 성능을 향상시키게 된다.As the cover is made of a high-strength plastic material is installed in the area where the propeller shaft and the transmission are connected as described above, if a shock is transmitted during a crash of the vehicle, the shock absorbing cover is appropriately absorbed and reduced to reduce the impact response performance. In addition, the NVH performance of the vehicle is improved by appropriately absorbing and reducing vibration and shocks at the connection portion.
