본 발명은 차량의 유니버셜 조인트에 관한 것으로, 특히 유격을 방지하여 진동 및 소음의 발생을 최소로 줄이도록 한 유격방지용 유니버셜 조인트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a universal joint of a vehicle, and more particularly, to a clearance preventing universal joint, which minimizes the occurrence of vibration and noise by preventing clearance.

종래의 유니버셜 조인트(10)는 제1도와 제2도에 나타낸 바와같이, 요크공(18)이 형성된 결합편(19)이 한쌍의 요크(11)와: 상기 요크(11)의 결합편(19)에 결합되는 십자축과: 상기 십자축(12) 각각의 축에 결합되는 니들베어링(13a, 13b) 및 스냅링(14)으로 구성하였다.In the conventional universal joint 10, as shown in FIG. 1 and FIG. 2, a coupling piece 19 having a yoke hole 18 is provided with a pair of yokes 11: a coupling piece 19 of the yoke 11. Cross-shaft coupled to :) and the needle bearing (13a, 13b) and the snap ring 14 coupled to each axis of the cross-shaft (12).

그러나 이러한 종래의 유니버셜 조인트(10)는 각도를 가진 두축 사이로 동력을 전달할 때, 십자축(12)과 니들베어링(13a)의 접촉면에 갭이 발생하여 동력전달시 진동 및 소음이 발생하는 문제점이 있었다.However, when the conventional universal joint 10 transmits power between two axes having an angle, a gap occurs in the contact surface between the cross shaft 12 and the needle bearing 13a, which causes vibration and noise during power transmission. .

따라서 본 발명은 상기한 문제점을 해소하기 위하여 창안한 것으로, 그 목적은 유니버셜 조인트의 갭의 발생을 방지하여 진동 및 소음발생을 억제시킬 수 있도록 하는 유격방지용 유니버셜 조인트를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide a clearance preventing universal joint that can suppress the occurrence of gaps in the universal joint and suppress vibration and noise.

위와 같은 목적을 달성하기 위하여 본 발명는 요크공의 내주면 외측과 내측에 걸림흠과 걸림턱을 형성한 요크와: 상기 요크의 걸림흠에 삽입하는 접시스프링과: 상기 요크 걸림턱에 삽입하는 톱니붙이와셔와: 상기 요크공에 삽입되고, 내주면에 테이퍼부를 형성한 한쌍의 니들베어링과: 상기 니들에어링의 테이퍼부와 대응되는 테이퍼부를 축 외주면에 형성한 십자축으로 구성함을 기본 특징으로 한다.In order to achieve the above object, the present invention is a yoke and the locking groove and the locking jaw formed on the inner and outer circumferential surface of the yoke hole: a plate spring inserted into the locking groove of the yoke: a toothed washer inserted into the yoke locking jaw And a pair of needle bearings inserted into the yoke hole and having a tapered portion on the inner circumferential surface, and a cross axis formed on the outer circumferential surface of the tapered portion corresponding to the tapered portion of the needle air ring.

위와같이 구성된 본 발명의 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

제3도와 제4도에 나타낸 바와같이, 요크(11)는 결합편(19)에 요크공(18)을 형성하되, 상기 요크공(18)에 걸림흠(18a), 걸림턱(18b)을 형성한다. 또한 상기 걸림흠(18a)에 접시스프링(16)을 삽입한다. 상기걸림흠(18a)에 삽입된 접시스프링에 다시 니들베어링(13a)을 삽입하고, 니들베어링(13a)의 후단에 톱니붙이와셔(17)를 삽입한 다음 또다른 니들베어링(13b)을 삽입한다. 상기 니들베어링(13a, 13b)의 삽입부 내주면에 테이퍼부(18a)를 각각 형성시키고, 상기 테이퍼부(15a)에 십자축(12)의 축을 삽입하여 결합시키되, 상기 십자축의 축 외주면에 테이퍼부(15b)를 형성한다.As shown in FIG. 3 and FIG. 4, the yoke 11 forms a yoke hole 18 in the engaging piece 19, and the yoke hole 18 has a catch 18a and a catching jaw 18b. Form. In addition, the dish spring 16 is inserted into the catch 18a. The needle bearing 13a is again inserted into the dish spring inserted into the jamming portion 18a, the toothed washer 17 is inserted into the rear end of the needle bearing 13a, and then another needle bearing 13b is inserted. . Tapered portions 18a are formed on the inner circumferential surfaces of the insertion portions of the needle bearings 13a and 13b, respectively, and the shafts of the cross shafts 12 are inserted into the tapered portions 15a, and the tapered portions are coupled to the outer circumferential surfaces of the cross shafts. It forms 15b.

이러한 본 발명의 작용 및 효과를 설명하면, 제3도에 나타낸 바와 같이 니들베어링(13a, 13b)의 마모발생으로 십자축(12)의 갭 발생시 접시스프링(16)이 탄성에 의하여 요크(11)의 마운팅면에 활주하여 니들베어링(13a)을 압압하여 갭을 제거하게됨과 동시에 니들베어링(13a)과 니들베어링(13b) 사이에 설치된 톱니붙이와셔(17)의 탄성에 의하여 니들베어링(13a) 상측으로 압입하므로 갭 발생을 억제한다. 따라서 유니버셜 조인트(10)의 수명을 최대로 연장하며, 갭의 발생으로 인한 진동 및 소음을 억제시킨다.Referring to the operation and effects of the present invention, as shown in FIG. 3, the yoke 11 is caused by the elasticity of the disc spring 16 when the gap of the cross shaft 12 occurs due to abrasion of the needle bearings 13a and 13b. The needle bearing 13a is slid to the mounting surface to remove the gap, and at the same time, the upper side of the needle bearing 13a is caused by the elasticity of the toothed washer 17 installed between the needle bearing 13a and the needle bearing 13b. Since press-fitting is performed, the gap is suppressed. Therefore, it extends the life of the universal joint 10 to the maximum, and suppresses the vibration and noise caused by the generation of the gap.

이상에서 살펴본 바와같이 본 발명은 유니버셜 조인트에 마모가 발생하더라고 갭의 발생을 제거하므로 유니버셜 조인트의 수명을 연장시킨뿐 아니라, 동력전달시 진동 및 소음 발생을 억제시킬 수 있는 것이다.As described above, the present invention eliminates the occurrence of gaps even though abrasion occurs in the universal joint, thereby extending the life of the universal joint as well as suppressing vibration and noise generation during power transmission.
