Abstract

The present invention relates to a tripod type constant velocity joint allowing a strike outer to be coupled to a central part of a perpendicular surface of a spider trunnion through a bolt, thereby preventing a needle roller, an inner roller, and an outer roller from escaping from the spider trunnion. The tripod type constant velocity joint comprises a housing, a shaft, a spider, a needle roller, an inner roller, an outer roller, and a strike outer. The housing transfers rotational power of an engine and has three track grooves formed on the interior thereof. The shaft receives the transferred rotational power of the housing to be rotated. The spider is connected to one end of the shaft to connect the housing with the shaft, is installed on the interior of the housing, and has a tripod type-trunnion formed thereon. The needle roller is installed on an outer circumferential surface of the spider trunnion. The inner roller is installed on an outer circumferential surface of the needle roller. The outer roller is installed on an outer circumferential surface of the inner roller to be in contact with the inner surface of the housing and slides in an axial direction of the housing. The strike outer is installed on the central part of the perpendicular surface of the spider trunnion to prevent deviation of the needle roller and the inner roller.

Description

트라이포드 타입 등속조인트{Tripod type constant velocity joint}[0001] The present invention relates to a tripod type constant velocity joint,

본 발명은 트라이포드 타입 등속조인트에 관한 것으로서, 좀더 세부적으로 말하자면 리테이너링을 제거하고 스트라이커 아우터의 결합방식을 변경 함므로써 내구성 증가 및 NVH(소음,진동) 성능을 향상시키고, 부품수를 절감함으로써 중량절감 및 원가절감을 하는 트라이포드 타입 등속조인트에 관한 것이다.The present invention relates to a tripod-type constant-velocity joint. More specifically, the present invention improves the durability and NVH (noise and vibration) performance by removing the retainer ring and changing the striker outer attachment method, The present invention relates to a tripod-type constant velocity joint for reducing the cost and cost.

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 등속 조인트는 구동축과 피동축의 교차각이 큰 경우에도 등속으로 원활하게 동력을 전달할 수 있기 때문에 독립 현가 방식의 전륜 구동차의 액슬축에 주로 사용되며, 샤프트를 중심으로 엔진측은 트라이포드 타입 조인트로 이루어지고, 샤프트를 중심으로 타이어측은 볼 타입 조인트로 이루어진다. Since the constant velocity joint can transmit power smoothly at a constant speed even when the intersection angle of 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 tire side is made of a ball type joint around the shaft.

도 1은 일반적인 등속 조인트의 단면 구성도이고, 도 2는 도 1의 A-A선 단면 구성도이다. Fig. 1 is a sectional view of a constant velocity joint; Fig. 2 is a sectional view taken along the line A-A in Fig. 1;

도 1에 도시되어 있는 바와 같이 일반적인 등속 조인트의 구성은, 엔진(도시되지 않음)의 회전동력을 전달하며 내부에 3개의 트랙홈이 형성되어 있는 하우징(2)과, 상기 하우징(2)의 회전동력을 전달받아서 회전되는 샤프트(1)와, 상기 하우징(2)과 샤프트(1)를 연결하기 위하여 상기 샤프트(1)의 일단에 연결되어 상기 하우징(2)의 내부에 설치되며 트라이포드 타입의 트러니언이 형성되어 있는 스파이더(3)와, 상기 스파이더(3) 트러니언의 외주면에 설치되는 니들롤러(6)와, 상기 니들롤러(6)의 외주면에 설치되는 인너롤러(5)와, 상기 인너롤러(5)의 외주면에 설치되어 상기 하우징(2)내면을 접촉하며 하우징 축방향으로 슬라이딩 하게 되는 아웃터롤러(4)와, 상기 니들롤러(6) 및 인너롤러(5)의 상단에 설치되는 스트라이크 아우터(7)와, 상기한 스트라이크 아우터(7)의 이탈을 방지하기 위한 리테이너링(8)과, 상기 하우징(2)에 일단이 연결되고 상기 샤프트(1)에 일단이 연결되는 부트(9)와, 상기 부트(9)를 각각 고정시키기 위한 고정 밴드(9a,9b)를 포함하여 이루어진다.As shown in Fig. 1, the configuration of a constant velocity joint is composed of a housing 2 having three track grooves formed therein for transmitting rotational power of an engine (not shown) A shaft 1 connected to one end of the shaft 1 for connecting the housing 2 and the shaft 1 and being installed inside the housing 2, A needle roller 6 provided on an outer circumferential surface of the trunnion 3; an inner roller 5 provided on an outer circumferential surface of the needle roller 6; An outer roller 4 installed on the outer circumferential surface of the inner roller 5 and contacting the inner surface of the housing 2 and sliding in the axial direction of the housing; A strike outer 7, A retainer ring 8 for preventing disengagement of the boot 7, a boot 9 whose one end is connected to the housing 2 and whose one end is connected to the shaft 1, And fixing bands 9a and 9b.

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 아웃터롤러(4), 인너롤러(5), 니들롤러(6)를 통해 스파이더(3) 트러니언으로 전달됨으로써 스파이더(3) 배럴에 연결되어 있는 샤프트(1)를 회전시킨다.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, The inner roller 5 and the needle rollers 6 to rotate the shaft 1 connected to the spider 3 barrel by being transmitted as a trunnion.

한편, 트라이포드 타입 조인트측의 부트(9)는 각각 트라이포드 타입 조인트를 감싸 밀봉시킴으로써 트라이포드 타입 조인트가 외부 오염물질에 의해 손상되는 것을 방지한다.On the other hand, the boots 9 on the side of the tripod type joint each enclose and seal the tripod type joint to prevent the tripod type joint from being damaged by external contaminants.
