Description
본 고안은 자동차 전륜구동축의 트라이포드 스파이더의 리테이너 구조에 관한 것으로서 더욱 상세하게는 스파이더에 조립되는 로울러와 니이들의 이탈을 방지하기위한 리테이너의 형상을 개선한 것에 관한 것이다.The present invention relates to a retainer structure of a tripod spider of an automobile front wheel drive shaft, and more particularly, to an improved shape of a retainer for preventing detachment of rollers and needles assembled to a spider.
자동차는 엔진의 폭발력을 구동바퀴에 전달하여 자동차를 옴직이게되는데, 이에 필요한 것이 변속기, 클러치, 각종의 동력전달축, 조인트등과 같은 동력전달장치이다.The car transmits the explosive power of the engine to the driving wheels, and the car is omnipresent. What is required is a power transmission device such as a transmission, a clutch, various power transmission shafts, a joint, and the like.
상기 동력전달장치의 하나인 트라이포드조인트는 변속기와 연결된 주동축과 구동바퀴에 연결되는 종동축사이에 개제되어 동력을 전달하는 것이다.The tripod joint, which is one of the power transmission devices, is interposed between a main shaft connected to a transmission and a driven shaft connected to a driving wheel to transmit power.
상기 트라이포드조인트는 제 1 도에서와 같이 주동축(10)과 연결된 조인트 하우징(11)내에 종동축(12)과 연결고정된 스파이더어셈블리(13)를 마련한다.The tripod joint is provided with a spider assembly 13 fixed to the driven shaft 12 in a joint housing 11 connected to the main shaft 10 as shown in FIG.
상기 조인트하우징(11)의 단부와 종동축(12)이 겹쳐지는 부위에는 부트(14)를 구비하여 조인트하우징(11)내에 이물질등이 침투하는 것을 방지한다.A boot 14 is provided at a portion where the end portion of the joint housing 11 and the driven shaft 12 overlap each other to prevent foreign matter or the like from penetrating into the joint housing 11.
상기 스파이더어셈블리(13)는 제 2 도에서와 같이 중심에 종동축고정홀(15)을 가지며, 이에 120°등간격으로 트러니언(16)를 가지고, 상기 트러니언(16)에는 조인트하우징(11)내면과 마찰시 원할한 회전을 위한 트라이포드로울러(17)가 구비된다.The spider assembly 13 has a driven shaft fixing hole 15 at the center as shown in FIG. 2, which has trunnions 16 at equal intervals of 120 ° and a joint housing 11 in the trunnions 16. FIG. Tripod roller 17 is provided for smooth rotation with the inner surface.
상기 트러니언(16)와 트라이포드로울러(17)사이에는 비교적 레디얼하중에 강한 니이들(18)을 설치하여, 과다한 회전과 진동에도 적절히 대처할 수 있도록한다.Between the trunnion 16 and the tripod roller 17, a needle 18, which is relatively strong against a radial load, is installed to properly cope with excessive rotation and vibration.
상기와 같이 구성된 스파이더어셈블리(13)는 엔진의 고회전을 구동바퀴로 전달하는 역할을 함으로 트라이포드로울러(17)와 니이들(18)에는 원심력과 진동에 의해서 트리니언(16)외측으로 이탈할 수 있는 위험성을 내포하고 있다.The spider assembly 13 configured as described above serves to transfer the high rotation of the engine to the driving wheel, so that the tripod roller 17 and the needle 18 can be separated out of the triion 16 by centrifugal force and vibration. Poses a risk.
상기와 같이 트러니언(16)에 구성된 부품의 이탈을 방지하기위해서 트러니언 (16)의 끝단에 리테이너링(20)과 리테이너(21)를 구비한다.The retainer ring 20 and the retainer 21 are provided at the end of the trunnion 16 in order to prevent the detachment of the components constituted in the trunnion 16 as described above.
상기 리테이너(21)와 리테이너링(20)의 장착상태를 살펴보면, 트러니언(16)의 끝단에 리테이너(21)를 삽입한 후, 이를 고정하기위해서 다시 리테이너링(20)을 리테이너(21)의 내측평면(22)자 트러니언(16)의 고정홈(19)이 동시에 걸릴 수 있도록 삽입 고정한다.Looking at the mounting state of the retainer 21 and the retainer ring 20, after inserting the retainer 21 at the end of the trunnion 16, the retainer ring 20 again to fix the retainer 21 of the retainer 21 Insertion and fixation so that the fixing groove 19 of the inner plane 22, the trunnion 16 can be caught at the same time.
상기와 같이 트라이포드로울러와 니이들을 고정하기위해서는 리테이너링과 리테이너등 많은 부품이 사용되고, 이로인해 조립공정수가 증가하여 조립성이 저하하고 제작시간과 생산원가가 증가하는 원인이 되었다.As described above, in order to fix the tripod roller and the needle, many parts such as a retainer ring and a retainer are used, and as a result, the number of assembling processes increases, resulting in deterioration of assemblability and increase in production time and production cost.
이에 본 고안에서는 상기한 여러 가지의 문제점들을 해결하기위해서 안출된 것으로서 리테이너의 형상과 리테이너가 조립되는 돌기부의 형상을 개선하여 부품수를 감소하여 조립성과 생산원가를 절감하기위함이다.Therefore, the present invention is designed to solve the above-mentioned problems, to improve the shape of the retainer and the shape of the protrusion to which the retainer is assembled to reduce the number of parts and to reduce the assembly and production cost.

제 3 도는 본 고안이 적용된 스파이더어셈블리의 단면도, 제 4 도는 본 고안의 요부인 스파이더리테이너의 평면도와 일부단면도로서 함께 설명을 한다.3 is a cross-sectional view of a spider assembly to which the present invention is applied, and FIG. 4 is a plan view and a partial cross-sectional view of a spider retainer which is a main part of the present invention.
자동차의 동력전달장치의 하나인 트라이포드조인트에서 조인트하우징내에 결합되는 스파이드어셈블리가운데 스파이드로울러와 니이들의 이탈을 방지하기 위한 리테이너의 형상을 박판의 금속을 프레스에 의해서 성형하여 리테이너만으로도 리테이너링과 리테이너의 역할을 수행할 수 있도록 한 것이다.In the triple assembly, which is one of the power transmission devices of automobiles, the shape of the retainer to prevent the detachment of the spider and needle from the spider assembly, which is incorporated in the joint housing, is formed by pressing a thin sheet of metal to retain the retaining ring and retainer. It is to be able to perform the role of.
상기 리테이너(21)는 제 4 도에서와 같이 박형의 원판을 이용하여 프레스에 의한 엠보스부(23)와 펀칭부(24)를 갖는다.The retainer 21 has an emboss portion 23 and a punching portion 24 by pressing using a thin disc as shown in FIG.
상기 엠보스부(23)는 원판의 하단에 절곡형상을 부여하여 스파이더의 트러니언(16)에 조립한 후 스파이더로울러(17)와 니이들(18)에 의한 이탈저항을 크게하고, 상기 펀칭부(24)는 트리니언(16)에 초기조립시 조립방향과의 반대방향으로 탄성력을 갖게하여 원할한 조립이 가능하게하고, 조립후에는 반발력에 의해 고정홈 (19)에 견고히 고정될 수 있게한다.The embossing part 23 is provided with a bent shape at the lower end of the disc, assembled to the trunnion 16 of the spider, and then the separation resistance by the spider roller 17 and the needle 18 is increased, and the punching part The 24 has an elastic force in the opposite direction to the assembly direction during the initial assembly of the triion 16 to enable smooth assembly, and after assembly, it can be firmly fixed to the fixing groove 19 by the repulsive force. .
또한, 리테이너(21)의 외측으로는 비교적 넓은 걸림턱(25)을 구비하여 니이들(18)과 스파이더로울리(17)를 동시에 리테이닝 할 수 있게하여 리테이닝효과를 배가 시키도록 한다.In addition, the outer side of the retainer 21 is provided with a relatively wide locking jaw 25 to allow the needle 18 and the spider roller 17 to be retained at the same time to double the retaining effect.
상기와 같은 리테이너(21)가 조립되는 스파이드트러니언(16)의 고정홈(19)은 리테이너(21)의 펀칭부(24)가 이루는 각도와 동일한 각도의 경사면(26)을 지니게하여 리테이너(21)가 트러니언(16)의 하단으로 밀리는 현상을 방지하였다.The fixing groove 19 of the spider trunnion 16 to which the retainer 21 as described above has the inclined surface 26 at the same angle as the angle formed by the punching portion 24 of the retainer 21 to retain the retainer 21. ) Is prevented from being pushed to the bottom of the trunnion 16.
상기와 같이 구성된 본 고안의 작용상태를 살펴보면; 박형의 원판에 엠보스부와 펀칭부를 가지는 리테이너를 스파이더에 120°등간격으로 형성된 돌기에 삽입고정한다.Looking at the operating state of the present invention configured as described above; A retainer having an embossed portion and a punching portion on a thin disc is inserted and fixed to a projection formed at equal intervals 120 degrees on the spider.
상기 리테이너(21)를 트러니언(16)에 조립할 경우 리테이너(21)의 내경에 형성된 펀칭부(24)에 탄성력에 의한 휨이 조립방향과의 반대방향으로 발생하게되고, 이에 따라 리테이너(21)는 트러니언(16)의 고정홈(19)에 안착하게된다.When assembling the retainer 21 to the trunnion 16, bending caused by elastic force occurs in the punching portion 24 formed in the inner diameter of the retainer 21 in the direction opposite to the assembly direction, and thus retainer 21. Is seated in the fixing groove 19 of the trunnion (16).
상기와 같이 고정홈(19)에 안착한 리테이너(21)의 펀칭부(24)는 반발력에 의해서 고정홈(19)에 끼이듯이 고정된다.As described above, the punching portion 24 of the retainer 21 seated in the fixing groove 19 is fixed as if being pinched in the fixing groove 19 by the repulsive force.
싱기와 같이 고정홈(19)에 안착된 리테이너(21)는 고정홈(19)의 하단에 형성된 경사면(26)에 의해서 더 이상 트러니언(16)의 하단으로 밀리지않고 단시간에 제자리를 찾게된다.The retainer 21 seated in the fixing groove 19 like the singer is not pushed to the lower end of the trunnion 16 by the inclined surface 26 formed at the lower end of the fixing groove 19 and finds its position in a short time.
상기와 같이 고정된 리테이너(21)는 외측에 형성된 걸림턱(25)을 이용하여 스파이더로울러(17)와 니이들(18)을 동시에 리테이닝 할 수 있게된다.The retainer 21 fixed as described above can retain the spider roller 17 and the needle 18 at the same time by using the locking step 25 formed on the outside.
상기와 같이 리테이너의 형상을 개선함으로서 조립이 원할하고, 생산라인의 조립시간을 단축시키게된다.By improving the shape of the retainer as described above, assembling is desired and the assembly time of the production line is shortened.
이상과 같이 구성된 본 고안인 자동차 전륜구동축의 트라이포드 스파이더의 리테이너 구조는 부품의 단일성을 이룰 수 있어 부품의 수가 감소되고, 이에의한 생산성의 향상과 조립단가의 절감을 이룰 수 있는 유용한 고안이다.The retainer structure of the tripod spider of the vehicle front wheel drive shaft of the present invention configured as described above is a useful design that can achieve a unity of parts, thereby reducing the number of parts, thereby improving productivity and reducing assembly costs.
