Abstract

본 발명은 트리포드(Tripod)식 등속조인트에 관한 것으로서, 더욱 상세하게는 외륜내측에 형성되는 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 것으로서, 외륜(10) 내측에 안내면(22)을 갖는 축방향으로 3개의 트랙(20)이 형성되고, 상기 외륜(10)상에 소정의 조인트각을 갖으며 삽입되는 구동축(30)에 결합되는 스파이더(40)의 외주에는 선단에 상기 트랙(20)에 삽입되어안내면(22)과 구름 및 슬라이딩하는 구면로울러(34)가 니이들로울러(24)에 의해 회전가능하게 제공된 3개의 이축(32)이 구성되어 있는 트리포드식 등속조인트에 있어서, 상기 각각의 이축(32)사이에 외륜(10)측으로 볼(50)을 탄지시켜 구동축 일회전시 6회의 축력이 발생토록 함을 특징으로 한다.The present invention relates to a tripod type constant velocity joint, and more particularly, three tracks are formed in the axial direction formed inside the outer ring, and inserted into the tracks and have three spherical rollers with spherical rollers at the tip. The spherical roller is moved in the track when the drive shaft is rotated by a drive shaft having a) and compensates for each change, and a tripod-type constant velocity joint which transmits power, the guide surface (22) inside the outer ring (10) Three tracks 20 are formed in the axial direction with the outer ring 10 having a predetermined joint angle on the outer circumference of the spider 40 coupled to the drive shaft 30 inserted therein at the distal end of the track ( In the tripod constant velocity joint, in which three biaxial shafts 32 are inserted into the guide surface 22 and the rolling and sliding spherical rollers 34 are rotatably provided by the needle rollers 24. remind Tangier the ball 50 toward the outer ring 10 between each of the twin-screw 32, and thereby characterized in that the ever six axial force generated when the drive shaft at the rotational speed.

Claims

Three tracks 20 are formed in the axial direction with the guide surface 22 inside the outer ring 10, and a spider coupled to the driving shaft 30 inserted with a predetermined joint angle on the outer ring 10 ( On the outer circumference of 40) is a tripod constant velocity joint, which is composed of three biaxial shafts 32, which are inserted into the track 20 at the distal end and rotatably provided with a guide surface 22 and a rolling and sliding spherical roller 34. In this case, a portion of the spider 40 between each of the two shafts 32 is held in the radial direction so that a part of the outer ring 10 in the radial direction so as to generate six axial force in one rotation of the drive shaft Tripod type constant velocity joint.

According to claim 1, Bolt rack 52 is formed in the axial direction so that the ball 50 can be inserted between the track 20 and the track 20 of the outer ring 10, the bolt rack 52 The ball 50 is inserted so as to be able to move in the axial direction at the same time as the cloud on the ball groove formed to allow the movement in the radial direction of the ball 50 on the spicer 40 corresponding to the ball 50 ( 54, a ball seat 56 movably inserted into the ball groove 54 to support the ball, and a spring provided in the ball groove 54 to impart a force to push the ball seat 56 to the outer ring side ( 58. A tripod constant velocity joint comprising: 58).
