Description
본 발명은 트리포드(Tripod)식 등속조인트에 관한 것으로, 더욱 상세하게는 축력 발생을 저감하여 차량의 횡방향 진동을 감소시킴과 동시에, 외측원통형로울러의 구름방향 제어가 가능하도록 된 트리포드식 등속조인트에 관한 것이다.The present invention relates to a tripod type constant velocity joint, and more particularly, to a tripod type constant velocity joint which is capable of reducing lateral vibration of a vehicle by reducing axial force generation, Lt; / RTI >
종래의 트리포드식 등속조인트에 있어서는 내면에 축방향으로 안내면을 갖는 3개의 트랙홈이 형성된 하우징과, 상기 하우징의 트랙홈에 삽입되는 3개의 트리니언을 갖는 스파이더 조립체와, 상기 스파이더 조립체의 트리니언 선단에 각기 회전가능하게 내주면이 체결되고, 하우징의 트랙홈에 외주면이 회전가능하게 삽입되어 안내면과 구름접촉하는 구면로울러로 구성되어 있다.In a conventional tripod-type constant velocity joint, a spider assembly having a housing formed with three track grooves having a guide surface in the axial direction on the inner surface thereof, three spindle assemblies inserted into the track grooves of the housing, And a spherical roller having an inner circumferential surface rotatably attached to the tip end thereof and having an outer circumferential surface rotatably inserted into the track groove of the housing and in rolling contact with the guide surface.
이러한 종래의 트리포드식 등속조인트는 하우징의 트랙홈을 따라 구면로울러가 전동운동할 때 임의의 조인트각에서 추진축이 회전하여 스파이더 조립체가 하우징의 트랙홈상을 선회운동하게 되면, 구면로울러가 선회운동 및 조심운동을 동시에 흡수함과 동시에, 추진축에 인장 및 압축력이 축방향에 주기적으로 발생하게 되어 급발진의 운전조건에서 차량을 좌·우로 진동시키는 기진력으로 작용하게 되고, 이는 차량에 진동을 발생시켜 운전자의 불안감 및 불쾌감을 유발시키는 것이다.Such a conventional tripod-type constant velocity joint has a problem in that when the spherical roller moves along the track groove of the housing and the propeller shaft rotates at an arbitrary joint angle and the spider assembly rotates on the track groove of the housing, The driving force is absorbed at the same time and the tension and the compression force are periodically generated in the axial direction of the propeller shaft, so that it acts as a propulsion force to vibrate the vehicle to the left and right under the driving conditions of the sudden acceleration. Causing anxiety and discomfort.
또한, 종래의 트리포드식 등속조인트는 구면로울러가 선회운동할 때 구면로울러가 스트라이커아웃트에 압착되어 스트라이커아웃트와 로울러 단면과의 마찰저항이 증가하여 축력발생을 가져올 수 있는 요인이 되었다.In addition, in the conventional tripod type constant velocity joint, when the spherical roller is pivotally moved, the spherical roller is pressed against the striker outward so that the frictional resistance between the striker out and the roller cross section increases, which is a cause of axial force generation.
뿐만 아니라, 제7도의 (a)에 도시된 바와같이 구면로울러를 원통형로울러에 조립하기 위한 조립홈(21)을 키홈(c,h)과 같은 방식으로 형성시킴으로서 노치(Notch) 효과에 의한 응력집중 발생되는 이유로 원통형로울러의 두께를 두껍게 해야하며, 코너부위의 곡률 반경의 대한 특별한 관리가 요구되는 등의 부담을 가져올 수 있는 것이다.7 (a), the assembly groove 21 for assembling the spherical roller to the cylindrical roller is formed in the same manner as the keyways (c, h), so that the stress concentration due to the notch effect It is necessary to increase the thickness of the cylindrical roller and cause a burden such as a special control of the radius of curvature of the corner portion.
본 발명의 목적은 이와같은 문제점을 해결하기 위하여 발명된 것으로서, 외측원통형로울러와 내측구면로울러에서 선회운동 및 조심운동을 분리하여 흡수하도록 함으로서 축력 발생을 저감하여 차량의 횡방향 진동을 감소시키고, 외측원통형로울러의 구름방향 제어가 가능하도록 된 트리포드식 등속조인트를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an internal spherical roller and an internal spherical roller which absorb and separate the swing motion and the caution motion, And a tripod type constant velocity joint capable of controlling the rolling direction of the cylindrical roller.

제15도는 본 발명에 의한 제6실시예를 도시한 단면도로서, (a)는 결합상태의 구성을 나타낸 단면도이고, (b) 내지 (g)는 하우징(1)의 트랙홈(11)의 형상 및 외측원통형로울러(2)의 외부 형상이 각각 돌출된 형상으로서, (b)(c)는 사각형 형상으로 돌출된 것이고, (d)(e)는 반원형 형상으로 돌출된 것이며, (f)(g)는 사다리꼴 형상으로 돌출된 것이다. 이와같이 돌출된 외측원통형로울러(2)에서 오목한 부분은 가이드역할을 하는 것이고, 그외 부분은 하중을 지지할 수 있는 것이다.FIG. 15 is a cross-sectional view showing a sixth embodiment according to the present invention. FIG. 15 (a) is a cross-sectional view showing the structure of the engaged state, (B) and (c) are protruding in a quadrangular shape, (d) (e) are protruding in a semicircular shape, (f) ) Projected in a trapezoidal shape. The concave portion in the protruding outer cylindrical roller 2 serves as a guide, and the other portion can support the load.
이상의 설명에서와 같은 본 발명의 트리포드식 등속조인트에 의하면, 외측원통형로울러가 트랙홈의 축방향으로 움직일 때 구름방향의 제어가 가능하도록 하우징의 트랙홈에 안내홈 형상을 형성하여 선회운동과 조심운동이 분리 작동시키고, 상기 안내홈에 외측원통형로울러가 안내되어 구름방향 제어가 가능하게 되어 끼임 발생에 의한 마찰저항을 방지하며, 외측원통형로울러의 조립홈을 타원형상에 의해서 형성시킴으로서 응력집중을 완화할 수 있고, 내구성을 향상시킬 수 있는 동시에, 두께를 줄임으로서 부품의 공용화를 꾀할 수 있어 원가를 절감할 수 있는 효과가 있다.According to the tripod type constant velocity joint of the present invention as described above, when the outer cylindrical roller is moved in the axial direction of the track groove, a guide groove shape is formed in the track groove of the housing so as to control the rolling direction, And the outer cylindrical roller is guided to the guide groove to control the rolling direction, thereby preventing frictional resistance due to the occurrence of the pinching. By forming the mounting groove of the outer cylindrical roller by the elliptical shape, stress concentration is relieved The durability can be improved and the thickness can be reduced to enable the parts to be shared and the cost can be reduced.
