Description

수동변속기의 윤활구조{Structure for Lubricating of manual Transmission}Lubrication structure of manual transmission {Structure for Lubricating of manual Transmission}

본 발명은 수동변속기 내부의 윤활을 위한 윤활구조에 관한 것으로, 특히 자동차의 수동변속기의 입력 및 출력 샤프트로 오일을 공급하는 오일 가이드와 입,출력샤프트의 중공홀 사이의 틈새로 오일이 누출되는 것을 방지할 수 있도록 한 수동변속기의 윤활구조에 관한 것이다.The present invention relates to a lubrication structure for lubrication of a manual transmission. In particular, the oil leaks into a gap between an oil guide for supplying oil to an input and output shaft of a manual transmission of an automobile and a hollow hole of an input and an output shaft. It relates to a lubrication structure of a manual transmission that can be prevented.

일반적으로, 수동변속기는 엔진과 구동바퀴 사이에 설치되어 자동차의 주행상태 변화에 따른 엔진의 회전력을 증대시키거나 감소시키는 역할을 하며, 자동차를 후진시키는 역할도 동시에 수행하는 장치이다.In general, the manual transmission is installed between the engine and the driving wheel to increase or decrease the rotational force of the engine according to the change in the driving state of the vehicle, and is a device that simultaneously performs the role of reversing the vehicle.

이러한 수동변속기는 엔진과 연결되어 같이 회전하는 입력축과, 이 입력축과 나란하게 위치되고 종감속 장치와 연결되어 회전력을 전달하는 출력축과, 입력축 및 출력축 사이에 장착되어 각 변속단 및 후진 변속작용을 하는 동기장치로 이루어진다.The manual transmission is connected to the engine and rotates together with the output shaft, which is located in parallel with the input shaft and is connected to the longitudinal reduction gear to transmit rotational force, and is mounted between the input shaft and the output shaft to perform respective shift stages and reverse shifting operations. It consists of a synchronization device.

첨부된 도면의 도 1은 종래의 수동변속기의 일부분을 나타낸 것으로, 입력샤프트(2)의 끝단부는 베어링(8)에 의해 회전가능하게 지지되고, 이 입력샤프트(2)의 내측에 축방향으로 윤활을 위한 오일이 안내되는 중공홀(5)이 형성되며, 이 중공홀(5)의 일측단은 개방되어 이 부분을 통해 오일이 유입된다.1 of the accompanying drawings shows a part of a conventional manual transmission, the end of the input shaft (2) is rotatably supported by a bearing (8), axially lubricated inside the input shaft (2) Hollow hole 5 is formed is guided for the oil is formed, one end of the hollow hole 5 is open and the oil is introduced through this portion.

그리고, 상기 오일이 유입되는 중공홀(5)의 개방된 끝단부에는 입력샤프트(2) 외부로부터 상기 중공홀(5) 내로 오일이 유입되도록 안내하는 오일가이드(7)가 설치된다.In addition, an oil guide 7 for guiding oil to flow into the hollow hole 5 from the outside of the input shaft 2 is installed at the open end of the hollow hole 5 through which the oil is introduced.

상기 오일가이드(7)는 도 2에 도시된 것과 같이 원판형의 몸체부(71)와, 이 몸체부(71)의 중앙부에 일측으로 연장되게 형성되어 상기 입력샤프트(2)의 중공홀(5) 내로 삽입되는 가이드관부(72)로 이루어진다.The oil guide 7 is formed in the disk-shaped body portion 71 and the central portion of the body portion 71 to extend to one side as shown in Figure 2 hollow hole 5 of the input shaft (2) The guide tube portion 72 is inserted into).

따라서, 수동변속기 내부의 회전체에 의해 비산, 포집된 오일은 변속기 케이스(1)와 오일가이드(7) 사이를 거쳐 오일가이드(7)의 가이드관부(72)를 통해 중공홀(5) 내로 유입된 후, 중공홀(5)의 내주면에 형성된 오일공급홀(6)을 통해 각 변속단 기어(3)의 윤활 부분으로 공급되며 윤활작용을 하도록 되어 있다.Therefore, the oil scattered and collected by the rotor inside the manual transmission flows into the hollow hole 5 through the guide tube portion 72 of the oil guide 7 through the transmission case 1 and the oil guide 7. After that, through the oil supply hole 6 formed in the inner circumferential surface of the hollow hole 5 is supplied to the lubrication portion of each shift gear 3 and to be lubricated.

그러나, 상기와 같은 종래의 수동변속기는 상기 오일가이드(7)를 통해 중공홀(5) 내로 오일을 공급하며 윤활작용을 수행할 때, 중공홀(5) 내의 오일이 오일가이드(7)의 가이드관부(72)와 중공홀(5) 간의 틈새로 유출되어 윤활효율이 저하되는 현상이 발생하는 문제가 있다.However, when the conventional manual transmission as described above supplies oil into the hollow hole 5 through the oil guide 7 and performs lubrication, the oil in the hollow hole 5 is guided by the oil guide 7. There is a problem in that the phenomenon that the lubrication efficiency is lowered to flow out of the gap between the tube portion 72 and the hollow hole (5).

특히, 낮은 회전수로 운전되는 경우에는 각 변속단 기어(3) 및 싱크로나이저(4)로 공급되는 오일량보다 오일가이드(7)와 중공홀(5) 사이의 틈새로 유출되는 오일량이 더 많아지게 되므로 윤활성능 저하에 의한 내구력 저하가 유발된다.In particular, when operated at a low rotational speed, the amount of oil flowing out into the gap between the oil guide 7 and the hollow hole 5 is greater than the amount of oil supplied to each shift gear 3 and the synchronizer 4. It will cause a decrease in durability due to the reduction in lubrication performance.

이에 본 발명은 상기와 같은 문제점들을 해결하기 위하여 안출된 것으로, 입력 샤프트 및 출력 샤프트의 중공홀과 오일가이드 사이의 틈새로 윤활을 위한 오일이 누유되는 것을 방지할 수 있도록 한 수동변속기의 윤활구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the lubrication structure of the manual transmission to prevent oil leakage for lubrication in the gap between the hollow hole of the input shaft and the output shaft and the oil guide. The purpose is to provide.

이하, 첨부된 도면을 참조하여 본 발명에 따른 수동변속기의 윤활구조의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of the lubrication structure of the manual transmission according to the present invention with reference to the accompanying drawings will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 수동변속기의 일부분의 구조를 나타낸 부분 단면도로, 엔진과 연결된 입력샤프트(2)는 변속기 케이스(1) 내부에서 그의 일단부가 베어링(8)에 의해 회전가능한 상태로 지지되고, 입력샤프트(2)의 일측에는 변속단 기어(3) 및 싱크로나이저(4)가 구성되어 있다.3 is a partial cross-sectional view showing a structure of a part of a manual transmission according to the present invention, in which an input shaft 2 connected to an engine is supported in a transmission case 1 with its one end rotatable by a bearing 8; On one side of the input shaft 2, a shift gear 3 and a synchronizer 4 are configured.

그리고, 상기 입력샤프트(2)의 일단부에는 윤활을 위한 오일이 유입되는 중공홀(5)이 축방향으로 형성되며, 상기 중공홀(5)의 내주면에는 각 변속단 기어(3)의 윤활부분으로 연통되는 복수개의 오일공급홀(6)이 형성되어 있다.In addition, a hollow hole 5 through which oil for lubrication flows is formed in one end of the input shaft 2 in the axial direction, and an inner circumferential surface of the hollow hole 5 includes a lubrication portion of each shift gear 3. A plurality of oil supply holes 6 are formed in communication with each other.

또한, 상기 입력샤프트(2)의 끝단부와 변속기 케이스(1) 사이에는 비산된 오일을 입력샤프트(2)의 중공홀(5) 내로 안내하기 위한 오일가이드(70)가 설치되어 있는데, 이 오일가이드(70)는 도 4에 도시된 것과 같이, 대체로 원판형태를 갖는 몸체부(701)와, 상기 몸체부(701)의 중앙부에 일측으로 연장되게 형성되어 상기 입력샤프트(2)의 중공홀(5) 내로 삽입되는 가이드관부(702) 및, 상기 가이드관부(702)의 외주부에 상기 중공홀(5)의 내주면과 밀착되도록 삽입 설치되는고무재질의 실링재(703)로 이루어진다.In addition, an oil guide 70 is installed between the end of the input shaft 2 and the transmission case 1 to guide the scattered oil into the hollow hole 5 of the input shaft 2. As shown in FIG. 4, the guide 70 has a generally disc-shaped body portion 701 and a central portion of the body portion 701 extending to one side to form a hollow hole of the input shaft 2. 5) It consists of a guide pipe portion 702 inserted into, and a rubber sealing material 703 is inserted to be installed in close contact with the inner circumferential surface of the hollow hole 5 in the outer peripheral portion of the guide tube 702.

따라서, 수동변속기 내부에서 회전체의 회전운동에 의해 비산된 오일은 상기 변속기 케이스(1)와 오일가이드(70) 사이를 거쳐 오일가이드(70)의 가이드관부(702)를 통해 중공홀(5) 내로 유입된 후, 입력샤프트(2)의 회전에 의해 각 오일공급홀(6)을 통해서 변속단 기어(3)의 윤활부분으로 공급된다.Therefore, the oil scattered by the rotational movement of the rotating body inside the manual transmission is passed through the transmission case 1 and the oil guide 70 through the guide pipe 702 of the oil guide 70 through the hollow hole 5 After being introduced into it, it is supplied to the lubrication portion of the gear stage 3 through each oil supply hole 6 by the rotation of the input shaft 2.

이 때, 상기 오일가이드(70)의 실링재(703)는 중공홀(5)의 내주면에 밀착된 상태이므로 가이드관부(702)와 중공홀(5) 간의 틈새를 완전히 메우게 되어 중공홀(5) 내의 오일이 외부로 누유되는 현상은 없게 된다.At this time, since the sealing member 703 of the oil guide 70 is in close contact with the inner circumferential surface of the hollow hole 5, the gap between the guide tube part 702 and the hollow hole 5 is completely filled, thereby the hollow hole 5. There is no phenomenon in which the oil inside leaks to the outside.

한편, 전술한 실시예에서는 상기 실링재(703)가 오일가이드(70)와 개별체로 되어 가이드관부(702)에 삽입 설치되는 것으로 설명하였으나, 이와 다르게 실링재가 오일가이드(70)의 가이드관부(702)의 외주면에 일체형으로 돌출되게 형성되어 중공홀(5)의 내주면에 밀착되도록 구성할 수도 있다.On the other hand, in the above-described embodiment, the sealing material 703 has been described as being inserted into the guide pipe portion 702 as a separate from the oil guide 70, the sealing material is different from the guide pipe portion 702 of the oil guide 70 The outer peripheral surface of the integrally formed to protrude may be configured to be in close contact with the inner peripheral surface of the hollow hole (5).

또한, 전술한 실시예에서는 상기 실링재가 부착된 오일가이드가 입력축 어셈브리에 적용된 것을 예로 들었으나, 상기와 같이 실링재가 구비된 구조의 오일가이드는 출력샤프트 쪽에도 동일하게 또는 유사하게 적용할 수 있을 것이다.In addition, in the above-described embodiment, the oil guide with the sealing material is applied to the input shaft assembly as an example, but the oil guide having the sealing material as described above may be applied to the output shaft in the same or similar manner. .

이상에서와 같이 본 발명에 따르면, 수동변속기 내에서 오일가이드와 입,출력 샤프트의 중공홀 간의 틈새가 없어지므로 중공홀 내로 유입된 오일이 외부로 누유되는 현상이 방지되고, 이로써 누유에 의한 윤활효율 저하를 방지할 수 있게 된다.As described above, according to the present invention, there is no gap between the oil guide and the hollow hole of the input and output shafts in the manual transmission, thereby preventing the oil flowing into the hollow hole from leaking to the outside, thereby lubricating efficiency by oil leakage. The fall can be prevented.
