Description
본 발명은 무단 변속기의 출력축 윤활홀에 관한 것으로서, 보다 상세하게는 무단 변속기의 제1고정 슬리브에 조립된 출력축의 부싱과 시일링 사이에 윤활홀을 뚫어 유체의 유동을 도모한 무단 변속기의 출력축 윤활홀에 관한 것이다.The present invention relates to an output shaft lubrication hole of a continuously variable transmission. More particularly, the output shaft lubrication of a continuously variable transmission is achieved by drilling a lubrication hole between the bushing and the sealing of the output shaft assembled in the first fixed sleeve of the continuously variable transmission. It's about the hall.
도1은 종래기술에 따른 무단 변속기의 출력축부를 도시한 도면으로, 무단 변속기의 출력축부(2)는 제1고정 슬리브(4)에 부싱(6)과, 시일링(8)을 개재한 후 조립되고 있다.1 is a view showing an output shaft portion of a continuously variable transmission according to the prior art, wherein the output shaft portion 2 of the continuously variable transmission is assembled after the bushing 6 and the sealing ring 8 are fitted to the first fixing sleeve 4. It is becoming.
상기 출력축부(2)는 부싱(6)을 개재하여 제1고정 슬리브(4)와의 상대운동을 가능하게 하고 축을 지지하게 하고 있다.The output shaft portion 2 allows relative movement with the first fixing sleeve 4 via the bushing 6 and supports the shaft.
특히, 부싱(6)은 고속으로 회전하는 출력축부(2)의 하중을 받으면서 마찰에 의한 마찰열을 발생하고 있다.In particular, the bushing 6 generates frictional heat due to friction while receiving the load of the output shaft portion 2 rotating at a high speed.
그래서 부싱(6)은 마찰과 하중에 취약한 부분이 되고 있다.Thus, the bushing 6 becomes a part vulnerable to friction and load.
따라서 유로(10)상에 부싱(6)등 마찰부분이 잠기게 후측 일단에만 시일링(8)을 개재하고 있기 때문에 이 부분은 사구간(12)이 되어 유체의 유동이 이루어지지 않게 되어 있다.Therefore, since the seal ring 8 is interposed only at the rear end portion so that the friction part such as the bushing 6 is locked on the flow path 10, this part becomes the four-segment 12 so that the fluid does not flow.
상기한 출력축부와 제1고정 슬리브 사이에 개재된 부싱의 일측은 시일링을 개재하여 윤활의 유동이 이루어지지 않는 사구간이 되는 문제점이 있다.One side of the bushing interposed between the output shaft portion and the first fixing sleeve has a problem that the lubrication flow is not made through the sealing ring.
따라서 출력축부의 유막 형성이나 부싱의 마찰열의 발열, 즉 냉각 성능에 취약한 문제점이 있다.Therefore, there is a problem in that the formation of the oil film of the output shaft portion or the heat generation of the frictional heat of the bushing, that is, the cooling performance is weak.
그리고 부싱의 작동을 예상할 수 없는 문제점이 있다.And there is a problem that the operation of the bushing can not be expected.
따라서 본 발명은 앞에서 언급한 바와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 무단 변속기의 제1고정 슬리브에 조립된 출력축의 부싱과 시일링 사이에 윤활홀을 뚫어 유체의 유동을 도모한 무단 변속기의 출력축 윤활홀을 제공하는데 있다.Therefore, the present invention has been invented to solve the above-mentioned problems, an object of the present invention is to facilitate the flow of fluid by drilling a lubrication hole between the bushing and the sealing of the output shaft assembled in the first fixed sleeve of the continuously variable transmission. To provide an output shaft lubrication hole for a continuously variable transmission.
도1은 종래기술에 따른 무단 변속기의 출력축부를 도시한 도면.1 is a view showing an output shaft of a continuously variable transmission according to the prior art.
도2는 본 발명에 따른 무단 변속기의 출력축 윤활홀을 도시한 도면.2 is a view showing the output shaft lubrication hole of the continuously variable transmission according to the present invention.
이를 실현하기 위한 본 발명은The present invention for realizing this
무단 변속기의 출력축과 제1고정 슬리브 사이에 개재되는 부싱과, 시일링 사이에 해당하는 출력축에 중공부와 연통하는 윤활홀 형성하여 이루어지는 무단 변속기의 출력축 윤활홀을 제공하는데 있다.The present invention provides a bushing interposed between an output shaft of a continuously variable transmission and a first fixing sleeve, and an output shaft lubricating hole of a continuously variable transmission formed by forming a lubricating hole communicating with a hollow portion in an output shaft corresponding to a sealing ring.
이하, 본 발명의 바람직한 구성 및 작용을 첨부한 도면에 의거하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, the preferred configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
도2는 본 발명에 따른 무단 변속기의 출력축 윤활홀을 도시한 도면으로, 무단 변속기의 출력축 윤활홀(20)은 무단 변속기의 출력축(24)과 제1고정 슬리브(26)사이에 개재되는 부싱(28)과, 시일링(30)사이에 해당하는 출력축(24)에 중공부(32)와 연통하게 뚫어 형성하고 있다.2 is a view showing an output shaft lubrication hole of the continuously variable transmission according to the present invention, wherein the output shaft lubrication hole 20 of the continuously variable transmission includes a bushing interposed between the output shaft 24 and the first fixed sleeve 26 of the continuously variable transmission. 28 and the output shaft 24 corresponding to the sealing ring 30 is formed in communication with the hollow portion 32.
상기한 바와 같이 이루어지는 본 발명의 작용은 출력축(24)의 중공부(32)를 통해 유동하는 오일이 윤활홀(20)을 통해 부싱(28)과 시일링(30)사이의 공간에 공급되어 순환하므로서 부싱(28)부분의 유막 형성이 향상된다.The operation of the present invention made as described above is the oil flowing through the hollow portion 32 of the output shaft 24 is supplied to the space between the bushing 28 and the seal ring 30 through the lubrication hole 20 and circulated This improves the oil film formation at the bushing 28.
따라서 부싱(28)과 출력축(24), 제1고정 슬리브(26)와의 사이에서 발생하는 마찰열의 발산이 용이하게 이루어진다.Therefore, the heat of friction generated between the bushing 28, the output shaft 24, and the first fixing sleeve 26 is easily made.
출력축과 제1고정 슬리브 사이에 개재된 부싱과 시일링의 사구간에 윤활홀을 통해 오일의 공급이 용이해 유막 형성이 증대되어, 부싱부분의 마찰열 발산이 효과적으로 이루어진다.The oil is easily formed through the lubrication hole between the bushing and the sealing ring interposed between the output shaft and the first fixing sleeve to increase the oil film formation, thereby effectively generating frictional heat of the bushing portion.
따라서, 무단 변속기의 내구성이 향상되어 애프터 써비스 비용이 절감된다.Therefore, the durability of the continuously variable transmission is improved, and after-sales service cost is reduced.
그리고, 부싱의 용량을 축소할 수 있어 경량화 가능한 효과가 있다.In addition, since the capacity of the bushing can be reduced, the weight can be reduced.
또한, 윤활홀을 형성하므로서 부싱 작동이 예상 가능하며 최적 설계를 도모하게 된다.In addition, by forming a lubrication hole, the bushing operation is predictable and achieves an optimal design.
