Description

트리포드 타입 등속조인트{Tripod type constant velocity joint}Tripod type constant velocity joint < RTI ID = 0.0 >

본 발명은 트리포드 타입 등속조인트에 관한 것으로서, 좀더 세부적으로 말하자면 샤프트와 스파이더를 볼 결합시킴으로써 축력저감 및 접촉부 마찰 마모량을 축소하고, 축력을 분산시켜 소음과 진동을 감소하는, 트리포드 타입 등속조인트에 관한 것이다.[0001] The present invention relates to a tripod-type constant velocity joint, and more particularly to a tripod-type constant velocity joint in which shaft and spider are ball-coupled to reduce axial force and abrasion wear of contact portion and reduce noise and vibration by dispersing axial force .

일반적으로 조인트는 회전축의 각도가 서로 다른 회전축에 회전동력(토크)을 전달하기 위한 것으로서, 동력전달 각도가 작은 추진축의 경우에는 후크 조인트, 플렉시블 조인트 등이 사용되고, 동력전달 각도가 큰 전륜 구동차의 구동축의 경우에는 등속 조인트가 사용된다. Generally, a joint is for transmitting rotational power (torque) to a rotation shaft having different angles of rotation axis. In the case of a propulsion shaft having a small power transmission angle, a hook joint, a flexible joint, or the like is used. A constant velocity joint is used.

상기 등속조인트는 구동축과 피동축의 교차 각이 큰 경우에도 등속으로 원활하게 동력을 전달할 수 있기 때문에 독립 현가 방식의 전륜 구동차의 액슬축에 주로 사용되며, 샤프트를 중심으로 엔진측(인보드측)은 트리포드 타입 조인트로 이루어지고, 샤프트를 중심으로 타이어측(아웃보드측)은 볼 타입 조인트로 이루어진다. Since the constant velocity joint can transmit power smoothly at a constant speed even when the angle of intersection between the drive shaft and the driven shaft is large, it is mainly used for the axle shaft of the independent suspension type front wheel drive vehicle, and the engine side (inboard side) Type joint, and the tire side (outboard side) around the shaft is made of a ball type joint.

도 1은 일반적인 트리포드 타입 등속조인트의 단면 구성도이고, 도 2는 종래의 트리포드 타입 등속조인트의 샤프트와 스파이더의 조립 사시도이고, 도 3은 도 2의 A-A선 단면도이다.FIG. 1 is a sectional view of a general tripod type constant velocity joint, FIG. 2 is an assembled perspective view of a conventional tripod type constant velocity joint shaft and a spider, and FIG. 3 is a sectional view taken along line A-A of FIG.

도 1 내지 도 3에 도시되어 있는 바와 같이 일반적인 등속조인트의 구성은, 샤프트(1)를 중심으로 엔진측(인보드측)은 트리포드 타입 조인트로 이루어지고, 샤프트(1)를 중심으로 바퀴측(아웃보드측)은 볼 타입 조인트로 이루어진다.As shown in Figs. 1 to 3, the construction of a constant-velocity joint in general is composed of a tripod-type joint around the shaft 1, an engine side (inboard side), a shaft- Outboard side) is made of a ball type joint.

본 발명은 트리포드 타입 등속조인트에 해당하는 것으로, 샤프트(1)를 중심으로 엔진측(인보드측)에 설치되어 있는 상기 트리포드 타입 등속조인트의 구성은, 엔진(도시되지 않음)의 회전동력을 전달하며 내부에 트랙홈(2a)이 형성되어 있는 하우징(2)과, 상기 하우징(2)의 회전동력을 전달받아서 회전되며 일단에 세레이션(1a)이 형성되는 샤프트(1)와, 상기 하우징(2)과 샤프트(1)를 연결하기 위하여 상기 샤프트(1)의 일단에 연결되어 상기 하우징(2)의 내부에 설치되며 외주면으로 3개의 트러니언(5)과, 중심원으로 세레이션(3a)이 형성되어 상기 트랙홈(2a)에 삽입되는 스파이더(3)와, 상기 샤프트(1)와 상기 스파이더(3)를 고정하는 써클립(6)과, 상기 트러니언(5)에 결합되어 하우징(2)의 내부에 설치되며 하우징(2)과 샤프트(1)의 마찰을 감소시키는 아우터롤러(4)와, 상기 스파이더(3)를 감싸기 위해 상기 하우징(2)의 일단과 상기 샤프트(1)에 일단에 고정되는 부트(7)와, 상기 부트(7)를 각각 고정시키기 위한 고정밴드(8)를 포함하여 이루어진다.The present invention corresponds to a tripod-type constant velocity joint. The structure of the tripod-type constant velocity joint provided on the engine side (inboard side) with respect to the shaft 1 is such that the rotational power of the engine (2), a shaft (1) rotated by receiving the rotational power of the housing (2) and having serration (1a) formed at one end thereof, and a shaft A trunnion 5 connected to one end of the shaft 1 for connecting the shaft 2 and the shaft 1 and installed inside the housing 2 as an outer circumferential surface, A spider 3 which is formed in the track groove 2a so as to be inserted into the track groove 2a and which is fixed to the shaft 1 and the spider 3; An outer roller 4 installed inside the housing 2 and reducing the friction between the housing 2 and the shaft 1, A boot 7 fixed at one end to the shaft 1 and one end of the housing 2 to cover the spider 3 and a fixing band 8 for fixing the boot 7 respectively .

상기 구성에 의한 일반적인 등속 조인트의 작용은 다음과 같다.The operation of a constant velocity joint according to the above construction is as follows.

엔진(도시되지 않음)으로부터 출력된 회전동력이 트랜스미션(도시되지 않음)을 거쳐 하우징(2)에 전달되면 하우징(2)이 회전되며, 이러한 하우징(2)의 회전동력은 아우터롤러(4)를 통해 스파이더(3)로 전달됨으로써 스파이더(3)에 연결되어 있는 샤프트(1)를 회전시킨다. 또한, 상기 샤프트(1)의 회전동력은 아우터 레이스(도시되지 않음)에 연결되는 바퀴를 회전시키게 된다.When the rotational power output from the engine (not shown) is transmitted to the housing 2 via a transmission (not shown), the housing 2 is rotated, and the rotational power of the housing 2 is transmitted to the outer roller 4 And is transmitted to the spider 3 to rotate the shaft 1 connected to the spider 3. In addition, the rotational power of the shaft 1 rotates a wheel connected to an outer race (not shown).

이 경우에, 샤프트(1)를 중심으로 엔진측(인보드측)에 설치되어 있는 트리포드 타입 등속조인트에서는 아우터롤러(4)가 하우징(2)의 트랙홈(2a)내를 슬라이딩 이동함으로써 아우터롤러(4)와 연관되어 있는 샤프트(1)의 회전 각도가 달라지게 되면서 차량의 변위에 따라 절각이 된다.In this case, in the tripod-type constant velocity joint provided on the engine side (inboard side) around the shaft 1, the outer roller 4 slides in the track groove 2a of the housing 2, The rotation angle of the shaft 1 associated with the wheel 4 is changed, and the rotation angle is changed according to the displacement of the vehicle.

그러나, 상기한 바와 같은 종래의 트리포드 등속 조인트는 상기 샤프트와 스파이더에 형성된 세레이션끼리 결합하여 써클링에 의해 결합 고정하면 상기 하우징에서 회전하면서 발생하는 소음과 진동이 축방향으로만 흡수하면서 등속 조인트의 내구성 성능을 저하하는 문제점이 있다.However, in the conventional tripod constant velocity joint as described above, when the serrations formed on the shaft and the spider are coupled and fixed by the ring ring, noise and vibration generated while rotating in the housing are absorbed only in the axial direction, There is a problem that the durability performance of the battery is deteriorated.

본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 상기 샤프트의 세레이션과 상기 하우징의 세레이션을 볼 세레이션으로 교체함으로서 축방향으로만 흡수하던 진동과 소음을 샤프트와 스파이더에서 고르게 분산하는 트리포드 타입 등속조인트를 제공하는데 있다.SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art by replacing the serration of the shaft and the serration of the housing with a ball serration so that the vibrations and noise absorbed only in the axial direction are transmitted to the shaft and the spider And to provide a uniformly distributed tripod-type constant velocity joint.

도 4 또는 도 5에 도시되어 있는 바와 같이, 본 발명의 일 실시예에 따른 트리포드 타입 등속조인트의 구성은, 내부에 트랙홈이 형성되어 있는 하우징의 회전동력을 전달받아서 회전되는 샤프트(10)와, 상기 하우징과 샤프트(10)를 연결하기 위하여 상기 샤프트(10)의 일단에 연결되어 상기 하우징의 내부에 설치되며 3개의 트러니언(50)이 형성되어 상기 트랙홈에 삽입되는 스파이더(30)와, 상기한 샤프트(10)의 일단에 볼(20)이 안착되는 샤프트(10) 볼가이드부(10a)와, 상기한 스파이더(30)의 내부에도 상기 볼(20)과 대응되는 볼가이드부(30a)와, 상기한 샤프트(10) 볼가이드부(10a)와 스파이더(30) 볼가이드부(30a)에 안착하는 볼(20)과, 상기한 볼(20)이 이탈하는 것을 방지하는 써클립(60)으로 형성되는 구조로 이루어진다.4 or 5, the structure of a tripod type constant velocity joint according to an embodiment of the present invention includes a shaft 10 rotated by receiving a rotational power of a housing having a track groove formed therein, A spider 30 connected to one end of the shaft 10 to connect the housing 10 to the shaft 10 and having three trunnions 50 formed in the housing and inserted into the track groove, A ball guide portion 10a having a shaft 10 on which a ball 20 is seated at one end of the shaft 10 and a ball guide portion 10b having a ball guide portion 10a corresponding to the ball 20 in the spider 30, A ball 20 seated on the ball guide portion 10a of the shaft 10 and the ball guide portion 30a of the spider 30, And a clip (60).

상기한 구성에 의한, 본 발명의 제1 실시예에 따른 트리포드 타입 등속조인트의 작용은 다음과 같다.The operation of the tripod type constant velocity joint according to the first embodiment of the present invention with the above construction is as follows.

트리포드 타입 등속조인트를 조립하는 경우에, 샤프트(10)의 볼가이드부(10a)에 볼(20)을 삽입시킨 후 스파이더(30)의 볼가이드부(30a)와 결합시킨다. 이 때, 써클립(60)을 샤프트(10)에 형성된 써클립홈부(60a)에 끼워 스파이더(30)가 샤프트(10)에서 이탈하는 것을 방지한다. The ball 20 is inserted into the ball guide portion 10a of the shaft 10 and then engaged with the ball guide portion 30a of the spider 30 when assembling the tripod type constant velocity joint. At this time, the servo clip 60 is fitted into the cotter groove portion 60a formed in the shaft 10 to prevent the spider 30 from coming off the shaft 10.

또한, 스파이더(30)와 써클립(60)과의 거리 틈새(C)가 형성된다. 그러므로, 아웃터롤러(40)가 하우징(20)내의 트랙홈(20a)에서 슬라이딩 이동하면서 발생하는 소음과 진동을 틈새만큼의 거리운동을 하면서 스파이더(30)로 축력을 분산시킨다. Further, a clearance C between the spider 30 and the paper clip 60 is formed. Therefore, the outer roller 40 disperses the axial force to the spider 30 while performing the distance movement of the noise and vibration generated as the sliding movement of the outer roller 40 in the track groove 20a in the housing 20.
