Description

차량용 추진축의 슬립 조인트 구조Slip joint structure of propulsion shaft for vehicle

본 고안은 차량용 추진축의 슬립 조인트 구조에 관한 것으로서, 보다 상세하게는 차량의 앞쪽에 설치되는 엔진의 구조력을 뒷바퀴에 전달하는 추진축의 슬립 조인트 구조를 개선하여 미끄럼 마찰을 저감하여 동력 전달을 용이하게 할 수 있도록 하는 차량용 추진축의 슬립 조인트 구조에 관한 것이다.The present invention relates to a slip joint structure of a propulsion shaft for a vehicle, and more particularly, to improve the slip joint structure of a propulsion shaft that transmits the structural force of an engine installed at the front of a vehicle to a rear wheel, thereby reducing sliding friction to facilitate power transmission. It relates to a slip joint structure of a propulsion shaft for a vehicle to be able to.

예컨대 엔진이 동력은 변속기를 거쳐 추진축에 의해 바퀴에 전달되며, 요철 도로의 주행에서 차축이 상하로 움직이기 때문에 추진축 길이의 신축이 필요하며, 변속기와의 각도 변동에 관계없이 엔진의 동력이 원활하게 차축에 전달하기 위해서 추진축 양단에 자재 이음이 있고, 추진축 중간부에는 슬립 조인트가 설치되어 있다.For example, the power of the engine is transmitted to the wheels by the propulsion shaft via the transmission, and because the axle moves up and down in the driving of uneven roads, it is necessary to expand and contract the length of the propulsion shaft, and the engine power is smoothly regardless of the angle change with the transmission. There are material joints at both ends of the propulsion shaft for transmission to the axle, and slip joints are installed at the middle of the propulsion shaft.

상기한 추진축은 강한 비틀림을 받으면서 고속으로 회전하기 때문에 이에 견디도록 속이 빈 강관이나 환봉으로 되어 있으며, 회전할 경우에 평형을 유지하기 위한 평형추와 길이 변화에 대응하는 슬립 조인트가 설치되어 있다.Since the propulsion shaft rotates at high speed while being subjected to strong torsion, the propulsion shaft is made of hollow steel pipe or round bar to withstand it, and a counterweight and a slip joint corresponding to the change of length are provided to maintain the equilibrium when rotating.

상기한 슬립 조인트는 출력축과 중공축이 스플라인 결합하는 구조로 이루어진다.The slip joint has a structure in which the output shaft and the hollow shaft are splined to each other.

그러나 종래의 슬립 조인트는 스플라인 결합으로 이루어지므로 금속 마찰에 의하여 미끄럼 저항이 크기 때문에 마모가 발생하기 쉬우며, 마모로 인하여 동력 전달에 악영향을 미치게 된다는 문제점이 있다.However, since the conventional slip joint is made of a spline coupling, wear is likely to occur due to the large sliding resistance due to metal friction, and there is a problem in that power transmission adversely affects transmission.

따라서 본 고안은 종래의 이러한 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 차량의 앞쪽에 설치되는 엔진의 구조력을 뒷바퀴에 전달하는 추진축의 슬립 조인트 구조를 개선하여 미끄럼 마찰을 저감하여 동력 전달을 용이하게 할 수 있도록 하는 차량용 추진축의 슬립 조인트 구조를 제공하는 데 있다.Therefore, the present invention is to solve such a conventional problem, the object of the present invention is to improve the slip joint structure of the propulsion shaft for transmitting the structural force of the engine installed in the front of the vehicle to the rear wheel to reduce the sliding friction to reduce power transmission. It is to provide a slip joint structure of a propulsion shaft for a vehicle that can be facilitated.

상기한 바와 같은 목적을 달성하기 위하여, 본 고안은 엔진의 동력을 변속기를 경유하여 뒷바퀴에 전달하는 추진축에 있어서, 이 추진축의 출력축 단면 형상을 다각형으로 하고, 이 출력축에 동일한 다각형으로 형성되는 중공을 보유하는 중공축을 설치하고, 이 중공축의 내부와 출력축의 외부에 롤러를 배치하는 것으로 이루어지는 차량용 추진축의 슬립 조인트 구조를 제공한다.In order to achieve the object as described above, the present invention in the propulsion shaft for transmitting the power of the engine to the rear wheel via the transmission, the output shaft cross-sectional shape of the propulsion shaft to a polygon, the hollow formed in the same polygon on the output shaft A slip joint structure of a propulsion shaft for a vehicle comprising a hollow shaft to be retained and rollers disposed on the inside of the hollow shaft and the outside of the output shaft is provided.

도 1은 본 고안에 의한 차량용 추진축의 슬립 조인트 구조가 적용되는 동력 전달 장치의 측면도.1 is a side view of a power transmission device to which a slip joint structure of a propulsion shaft for a vehicle according to the present invention is applied.

도 2는 도 1의 A - A선 단면도이다.FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1.

이하, 본 고안의 바람직한 구성 및 작용의 실시예를 첨부한 도면에 의거하여 더욱 상세히 설명한다.Hereinafter, on the basis of the accompanying drawings an embodiment of a preferred configuration and operation of the present invention will be described in more detail.

도 1은 본 실시예의 추진축이 적용되는 동력 전달 장치를 도시한 도면으로서, 이 동력 전달 장치는 엔진(1)의 동력을 변속기(3)를 경유하여 바퀴(5)에 전달하는 구조로 이루어진다.1 is a view showing a power transmission device to which the propulsion shaft of the present embodiment is applied, and the power transmission device is configured to transmit power of the engine 1 to the wheels 5 via the transmission 3.

상기한 추진축은 양측에 자재 이음(7)이 설치되며, 중앙에 슬립 조인트(9)가 설치되고, 회전의 균형을 용이하게 하는 평형추(11)가 배치되는 구조를 이루고 있다.The propulsion shaft has a structure in which material joints 7 are installed at both sides, slip joints 9 are installed at the center, and counterweights 11 are arranged to facilitate rotational balance.

상기한 슬립 조인트(9)는 차량의 상하 운동에 의하여 발생되는 추진축의 길이 변화에 대응하는 것으로서, 도 1 및 도 2에 도시한 바와 같이, 단면이 삼각형으로 형성되는 출력축(13)에 삼각형의 중공부를 형성하는 중공축(15)이 길이 방향으로 이동 가능하게 설치되며, 이 출력축(13)의 외주면과 중공축(15)의 내주면 사이에 롤러(17)를 설치하는 구조이다.The slip joint 9 corresponds to a change in the length of the propulsion shaft generated by the vertical movement of the vehicle. As shown in FIGS. 1 and 2, the hollow hollow of the triangle is formed on the output shaft 13 having a triangular cross section. The hollow shaft 15 which forms a part is provided so that a movement is possible in the longitudinal direction, and the roller 17 is provided between the outer peripheral surface of this output shaft 13 and the inner peripheral surface of the hollow shaft 15. As shown in FIG.

상기한 롤러(17)는 삼각형 형상의 각 변에 각각 설치되며, 상기한 출력축(13)과 중공축(15) 사이의 마찰을 구름으로 유도한다.The roller 17 is installed on each side of the triangular shape, and guides the friction between the output shaft 13 and the hollow shaft 15 to the cloud.

그래서 차량의 바퀴(5)가 주행하면서 상하 운동을 하게 되면, 추진축 양단의 자재 이음(7)에 의하여 각도가 조절되며, 이 각도의 변화에 의하여 발생되는 길이의 변화를 슬립 조인트(9)가 보상하게 된다.Thus, when the wheel 5 of the vehicle moves up and down while driving, the angle is adjusted by the material joints 7 at both ends of the propulsion shaft, and the slip joint 9 compensates for the change in length caused by the change of the angle. Done.

이때 상기한 슬립 조인트(9)는 길이 방향으로 구름 마찰을 하며 왕복 이동하게 된다.At this time, the slip joint 9 is reciprocated while rolling friction in the longitudinal direction.

상술한 바와 같이, 본 고안의 구조는 출력축의 내면과 중공축의 외면 사이가 구름 마찰을 하게 되므로 마모를 저감할 수 있으며, 이에 길이 방향으로의 신축이 용이하게 된다는 이점이 있다.As described above, the structure of the present invention has a rolling friction between the inner surface of the output shaft and the outer surface of the hollow shaft can reduce wear, there is an advantage that it is easy to stretch in the longitudinal direction.

본 고안은 기재된 실시예에 한정하는 것이 아니고, 본 고안의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형을 할 수 있음은 이 기술 분야에서 통상의 지식을 가진 자에게는 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 고안의 실용신안등록청구범위에 속한다 해야 할 것이다.The present invention is not limited to the embodiments described, it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention.
