It is about material joints.
Description
본 고안은 자동차 추진축(propeller shaft)에 장착되는 십자형 자재이음(universal joint)에 관한 것으로서, 더욱 상세하게는 요크(yoke)의 축공과 결합되는 니들 베어링의 베어링 부싱 내부에 돌기 및 요홈을 이용한 공간을 확보함으로서, 그리스를 충분히 주유할 수 있도록 개선한 자동차 추진축용 십자형 자재이음에 관한 것이다.The present invention relates to a universal joint mounted on a propeller shaft, and more particularly, a space using protrusions and grooves in a bearing bushing of a needle bearing coupled to a yoke shaft hole. The present invention relates to a cross-shaped joint for an automobile propulsion shaft which is improved to lubricate grease sufficiently by securing.
일반적으로 전기관 후륜 구동방식의 자동차는 변속기의 출력을 종감속 장치에 전달하는 추진축이 장착되어 있다.In general, an electric tube rear wheel drive vehicle is equipped with a propulsion shaft for transmitting the output of a transmission to a longitudinal reduction gear.
이러한 추진축에는 요철이 심한 노면을 주행할 때, 차륜의 진동으로 변속기 출력축과 종감속장치의 입력축이 이루는 각도 변화에 수시로 대응하도록 하는 십자형 자재이음이 설치되어 있다.These propulsion shafts are provided with cross-shaped joints that frequently respond to changes in the angle between the transmission output shaft and the input shaft of the longitudinal reduction gear due to the vibration of the wheels when driving on uneven roads.
이러한 십자형 자재이음은 제1도에 도시되는 바와 같이. 십자형상의 십자축(110)과. 그 십자축(110)에 횡방향 및 종방향으르 결합되도록 2개씩의 축공(121), (131)을 갖는 2개의 요크(121), (131)로 이루어져 있다.Such cross-shaped joints are shown in FIG. Cruciform axis (110) and. It consists of two yoke 121, 131 having two axial holes 121, 131 to be coupled to the cross shaft 110 in the transverse and longitudinal directions.
한편. 상기 십자축(110)은 상기 각 요크(120), (130)의 축공(121), (131)과결합되는 부위에 니들 베어링(l11)이 설치되어 있으며, 그 니들 베어링(111)에는 베어링 부싱(112)에 씌어져 있다.Meanwhile. The cross shaft 110 is provided with a needle bearing (1111) at a portion that is coupled to the shaft hole (121), 131 of the yoke (120), (130), the needle bearing 111, the bearing bushing It is written at (112).
이에 따라, 십자축(110)을 중심으로 이에 결합된 각 요크(120), (130)의 종. 힁방향으로의 유동에 의해 변속기 출력축과 종감속장치의 입력축이 이루는 각도의 변화에 대응할 수 있게 된다.Accordingly, the bell of each yoke 120, 130 coupled to the center around the cross-shaft (110). The flow in the X direction makes it possible to cope with a change in the angle formed by the transmission output shaft and the input shaft of the longitudinal reduction gear.
그러나. 추진축용 십자형 자재이음은 그 유용성에도 불구하고 십자축(110)의 윤활구조에 있어 문제점을 가지게 되었다. 즉, 십자축(110)의 니들베이링(111)에는 추진축의 고속 구동과 동시에 이루어지는 원활한 절곡변위 및 마모 방지를 위해 니들 그리스가 주입되는데,제2도에 도시되는 바와 같이. 니들 베어렁(111)에 씌어진 베어링 부싱(112)의 내부에는 헙소함으로 니들 베어링(111)의 구동에 필요로 하는 충분한 그리스를 주입할 수 없는 문제점이 있었다.But. The cross-shaped material joint for the propulsion shaft has a problem in the lubrication structure of the cross shaft 110 despite its usefulness. That is, needle grease is injected into the needle bearing ring 111 of the cross shaft 110 for smooth bending displacement and abrasion prevention at the same time as the high speed driving of the propulsion shaft, as shown in FIG. There was a problem in that sufficient grease needed for driving the needle bearing 111 could not be injected into the inside of the bearing bushing 112 written on the needle bare rung 111.
따라서. 본 고안은 상기와 같은 종래의 문제점을 감안하여 안출된 것으로서. 베어링 부싱내에 돌기 및 요홈을 통한 공간을 확보하여 그리스를 충분히 주유할 수 있는 자동차 추진축용 십자형 자재이음을 제공하는데 그 목적이 있다.therefore. The present invention is devised in view of the above conventional problems. The purpose of this invention is to provide a cross-shaped joint for automobile propulsion shaft which can fill grease sufficiently by securing space through protrusion and groove in bearing bushing.
