본 발명은 트리포드(Tripod)식 등속조인트에 관한 것으로서, 더욱 상세하게는 외륜 내측에 축방향으로 3개의 트랙이 형성되고, 상기 트랙에 삽입되며 선단에 구면로울러를 갖춘 3개의 이축(Trunion)을 갖는 구동축을 구비하여 구동축의 회전시 상기 구면로울러가 트랙내를 이동하며 각 변화를 보상함과 동시에 동력을 전달하는 트리포드식 등속조인트에 관한 것이다.The present invention relates to a tripod constant velocity joint, and more particularly, three tracks are formed in the outer ring in the axial direction, and inserted into the tracks, the three twin shafts having spherical rollers at the ends thereof. The spherical roller is provided with a drive shaft having a spherical roller is moved in the track and compensates for each change, and a tripod constant velocity joint for transmitting power at the same time.
이러한 등속포인트는 제3도 및 제4도에 도시된 바와 같이 외륜(10)내측에 안내면(22)을 갖는 축방향으로 3개의 트랙(20)이 형성되고, 상기 외륜(10)상에 소정의 조인트각을 갖으며 삽입되는 구동축(30)이 스파이더(40)에 스플라인(42)이 결합되어 있다. 그리고 상기 스파이더(40)의 외주면상에는 제2도에 상세히 도시된 바와 같이 선단에 상기 트랙(20)에 삽입되어 안내면(22)과 구름 접촉하는 구면로울러(34)가 니이들로울러(24)에 의해 회전가능하게 제공된 3개의 이축(32)이 일체로 구성되어 있다. 그러나, 이러한 등속조인트는 임의의 조인트각에서 전달되는 토오크에 의해 회전할때 1회전마다 3회의 축력(軸力)이 축방향으로 발생하게 된다. 이러한 축방향의 힘(축력)은 조인트 각도와 전달토오크 등에 의해 영향을 받으며 인장력 및 압축력으로 구분되어진다. 따라서 상기와 같은 트리포드식 조인트는 차량의 급발진시에 축력이 증대되어 측방향의 진동이 발생되고 있고, 특히 높은 엔진출력을 갖는 차량의 경우에는 축력의 발생주기가 차량의 고유진동수와 일치할 경우 차량의 측면진동이 더욱 심화되는 문제를 갖고 있었다.These constant velocity points are three tracks 20 are formed in the axial direction with a guide surface 22 inside the outer ring 10, as shown in Figures 3 and 4, the predetermined predetermined on the outer ring (10) The spline 42 is coupled to the spider 40 with the driving shaft 30 inserted into the joint angle. On the outer circumferential surface of the spider 40, as shown in detail in FIG. 2, a spherical roller 34 inserted into the track 20 at the tip and rolling contact with the guide surface 22 is formed by the needle roller 24. As shown in FIG. Three biaxially provided 32 rotatably are integrally formed. However, such a constant velocity joint generates three axial forces in one axial direction every revolution when rotated by a torque transmitted at an arbitrary joint angle. This axial force (axial force) is influenced by the joint angle and the transmission torque and is divided into tensile and compressive forces. Therefore, in the tripod joint as described above, the axial force is increased when the vehicle is suddenly started, and lateral vibration is generated. In particular, in the case of a vehicle having a high engine power, the occurrence period of the axial force coincides with the natural frequency of the vehicle. The side vibration of the vehicle was intensified.
이에 본 발명은 상기와 같은 제반 결함을 감안하여 안출된 것으로서, 그 목적은 축력을 감소시켜 차량의 측면진동을 최소화할 수 있는 트리포드식 등속조인트를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned defects, and an object thereof is to provide a tripod type constant velocity joint which can minimize lateral vibration of the vehicle by reducing the axial force.
이러한 본 발명의 목적은 상기 각각의 이축은 스파이더로부터 분리구성하고, 그 분리부가 상기 스파이더에 회전 가능하게 결합 구성하여 달성될 수 있다.The object of the present invention can be achieved by each biaxial configuration separated from the spider, the separation portion rotatably coupled to the spider.
즉, 이축을 스파이더로부터 분리하되 이축을 스파이더에 대해 회전 가능하도록 결합하여 구면로울러에 회전저항 및 슬라이딩저항이 걸릴 경우 이축이 자전을 이루어 저항을 감소시키므로써 축력을 감소시키게 되는 것이다.In other words, the biaxial shaft is separated from the spider, but the biaxial shaft is coupled to be rotatable with the spherical roller when the rotational resistance and sliding resistance is applied to the biaxial rotation to reduce the resistance by reducing the resistance.
이하, 본 발명을 첨부도면에 의거하여 좀더 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 발명의 바람직한 실시예가 도시되어 있는데, 이는 제2도에 상당하는 부분만을 발췌 도시한 것으로서, (종래와 동일 구성은 그 부호를 동일하게 부여하여 설명한다.) 이에 따르면 본 발명은 외륜(10)내측에 안내면(22)을 갖는 축방향으로 3개의 트랙(20)이 형성되고, 상기 외륜(100)상에 소정의 조인트각을 갖으면 삽입되는 구동축(30)이 스파이더(40)에 스플라인(42)결합되어 있다. 그리고 상기 스파이더(40)의 외주면상에는 선단에 상기 트랙(20)에 삽입되어 안내면(22)과 구름접촉하는 구면로울러(34)가 니이들로울러(24)에 의해 회전가능하게 제공된 3개의 이축(32)이 구성되어 있는 종래와 동일구성에 있어서, 상기 각각의 이축(32)은 스파이더(40)로부터 별개로 분리구성되고, 이축(32)의 일측면 하단부가 상기 스파이더(40)에 니이들로울러(44)를 개재하여 회전 가능하게 결합되어 있다.FIG. 1 shows a preferred embodiment of the present invention, which shows only a portion corresponding to FIG. 2 (the same configuration as in the prior art will be described with the same reference numerals). (10) Three tracks 20 are formed in the axial direction with the guide surface 22 therein, and the drive shaft 30 inserted into the spider 40 when the predetermined joint angle is formed on the outer ring 100 is formed. Spline 42 is coupled. On the outer circumferential surface of the spider 40, three biaxial shafts 32 are rotatably provided by the needle roller 24 with a spherical roller 34 inserted into the track 20 at the tip thereof and rolling contact with the guide surface 22. In the same configuration as that of the conventional configuration, the biaxial shaft 32 is separately configured from the spider 40, and one side lower end of the biaxial shaft 32 is needled to the spider 40 ( It is rotatably coupled via 44).
본 발명의 실시예에서는 상기 이축의 회전을 니이들 로울러지에 의해 가능케 하고 있으나 이는 일반적인 회전을 가능케 하는 볼 베어링 또는 부쉬 등의 다른 수단으로도 대체될 수 있을 것이다.In the embodiment of the present invention, the biaxial rotation is made possible by the needle roller, but this may be replaced by other means such as a ball bearing or a bush that enables general rotation.
상기 이축(32)의 하단은 구동축(30)상에 형성된 요홈(36)내로 연장되어 유동가능토록 삽입되는 것에 이해 회전동력 전달효율을 향상시킬 수 있게 될 것이다. 미설명부호 26은 스토퍼링이다.The lower end of the biaxial shaft 32 is extended to the groove 36 formed on the drive shaft 30 will be inserted to be able to flow will be able to improve the rotational power transmission efficiency. Reference numeral 26 is a stoppering.
이와 같이 구성된 본 발명은 구동축(30)의 회전에 의해 스파이더(40)가 회전하게 되고, 이때 구면로울러(34)가 트랙(200)내를 이동함과 동시에 회전을 이루게 되는데, 이러한 작동에 있어서 구면 로울러(34)는 회전과 동시에 슬라이딩을 이루게 되어 그로인해 이축(32)상에도 상기 회전 및 슬라이딩에 따른 저항이 전달되어 축력이 발생하게 된다. 이때 상기 이축(32)은 니이들로울러(44)에 의해 스파이더(40)와 회전 가능하게 결합되어 있으므로 스스로 저항이 걸리는 방향으로 자전을 이루게 된다. 따라서 상기 이축상에 걸리는 저항은 감소하게 되므로 이축(32)상에 발생되는 축력은 감소되어진다. 또한 이러한 이축(32)의 자전은 차량의 급발진시나 또는 출력이 높은 차량등에서는 상기 이축(32)상에 순간적으로 과부하가 걸리게 되므로 저항에 따른 과부하의 해소에 더욱 효과적으로 작용되어 축력저감효율이 높아질 것이다. 이러한 축력의 감소는 차량의 측방향의 진동을 최소화할 수 있게 될 것이다.In the present invention configured as described above, the spider 40 is rotated by the rotation of the drive shaft 30, and at this time, the spherical roller 34 moves in the track 200 and at the same time rotates. The roller 34 is slid at the same time as the rotation is rotated, thereby causing the resistance due to the rotation and sliding is transmitted on the biaxial 32, thereby generating axial force. At this time, since the biaxial shaft 32 is rotatably coupled to the spider 40 by the needle roller 44, the biaxial shaft 32 rotates in a direction in which resistance is applied. Therefore, the resistance on the biaxial axis is reduced, so that the axial force generated on the biaxial axis 32 is reduced. In addition, since the rotation of the biaxial shaft 32 is instantaneously overloaded on the biaxial shaft 32 when the vehicle is suddenly started or the vehicle has a high output, the biaxial shaft 32 acts more effectively to solve the overload caused by the resistance, thereby increasing the axial force reduction efficiency. . This reduction in axial force will be able to minimize the lateral vibration of the vehicle.
상술한 바와 같이 본 발명에 따른 트리포드식 등속조인트는 이축을 스파이더로부터 분리 구성하고, 이를 다시 스파이더에 회전가능하게 결합하여 회전 및 슬라이딩저항이 발생될 경우 상기 이축이 자전하며 저항을 감소시킬 수 있게 하므로써 축력을 저감하게 되고, 나아가서 차량의 측방향의 진동을 최소화할 수 있는 효과를 갖게 된다.As described above, the tripod constant velocity joint according to the present invention is configured to separate the biaxial from the spider, and to couple the same to the spider to be rotatable again so that the biaxial can rotate and reduce the resistance when rotation and sliding resistance is generated. As a result, the axial force is reduced, and furthermore, the lateral vibration of the vehicle is minimized.
