수동 변속기의 슬러지 제거형 윤활 구조Desludge type lubrication structure of manual transmission

본 발명은 수동 변속기의 윤활 구조에 관한 것으로서, 특히 입력 샤프트로부터 동기 장치에 오일이 공급될 때 슬러지가 퇴적되게 하여 동기 작용의 신뢰성이 향상되도록 한 수동 변속기의 슬러지 제거형 윤활 구조에 관한 것이다.The present invention relates to a lubrication structure of a manual transmission, and more particularly, to a sludge removing lubrication structure of a manual transmission in which sludge is deposited when oil is supplied from the input shaft to the synchronous device, thereby improving the reliability of the synchronous action.

수동 변속기에는 클러치로부터 동력을 전달받는 입력 샤프트 및 출력 샤프트가 내재되어 있고, 상기 입력 샤프트와 출력 샤프트가 변속기 케이스에 지지되면서도 용이하게 회전되도록 다수의 변속기용 베어링이 설치되어 있다.The manual transmission includes an input shaft and an output shaft that receive power from the clutch, and a plurality of transmission bearings are installed such that the input shaft and the output shaft are easily supported while being supported by the transmission case.

따라서, 상기 수동 변속기는 원할하게 작동되면서 변속 동력을 전달하기 위해 오일이 내재되어 있으며, 이 변속기용 오일이 베어링 및 기어치 등의 접동 마찰 부위에 윤활 및 냉각 작용을 하게 된다. 그리고, 변속기의 오일 공급 방식을 변속기에 내재된 오일을 기어류의 회전력으로 주변으로 비산시켜 각 샤프트 및 기어류에 공급하는 자연 윤활 방식이 일반적으로 이용되고 있다.Accordingly, the manual transmission is intrinsically oiled to transmit the shifting power while smoothly operating, and the oil for the transmission lubricates and cools the sliding frictional portions such as bearings and gear teeth. In addition, a natural lubrication method is generally used in which the oil supply method of the transmission is scattered to the periphery by the rotational force of the gears and supplied to each shaft and the gears.

여기서, 도 1은 5속 수동 변속기의 리어측이 도시되어 있는 바, 입력 샤프트(1)의 끝단이 변속기 케이스(5)에 볼 베어링(6)을 통해 지지되어 있고, 이 입력 샤프트(1) 상에는 3단 기어(21) 및 4단 기어(22) 등의 변속 기어(20)가 설치되어 있다.1 shows a rear side of a five-speed manual transmission, in which an end of the input shaft 1 is supported by the transmission case 5 through a ball bearing 6, and on this input shaft 1. Transmission gears 20 such as the third gear 21 and the fourth gear 22 are provided.

그리고 상기 3단 기어(21) 및 4단 기어(22) 사이에는 선택적으로 변속 동력을 전달할 수 있는 동기 장치(10)가 설치되어 있는 바, 이와 같은 동기 장치(10)는 확대도에 나타낸 바와 같이 입력 샤프트(1)에 결합된 허브 기어(12)와, 상기 허브 기어(12)의 외측에 결합되어 축방향으로 이동되는 슬리이브(13)와, 상기 3단 기어(21) 또는 4단 기어의 측면에 결합된 클러치 기어(14)와, 상기 슬리이브(13)와 클러치 기어(14) 사이에 위치되어 슬리이브(13) 이동시 클러치 기어(14)의 콘부에 밀착되면서 동기 회전이 이루어지도록 하는 싱크로나이저 링(15)으로 이루어져 있다.And between the third gear 21 and the fourth gear 22, there is provided a synchronous device 10 that can selectively transmit transmission power, such a synchronous device 10 as shown in the enlarged view The hub gear 12 coupled to the input shaft 1, the sleeve 13 coupled to the outside of the hub gear 12 and moved in the axial direction, and the third gear 21 or the fourth gear The clutch gear 14 coupled to the side and the synchro positioned between the sleeve 13 and the clutch gear 14 to be in close contact with the cone portion of the clutch gear 14 when the sleeve 13 is moved to achieve synchronous rotation. It consists of a niger ring (15).

한편 상기 입력 샤프트(1)의 내측에는 오일 통로(1a)가 형성되어 오일홀(1b)을 통해 3단 기어(21)와 허브 기어(12) 사이로 오일이 공급되고, 이 오일은 허브 기어(12)와 클러치 기어(14) 사이를 통해 싱크로나이저 링(15) 주변에 공급되면서 외측으로 빠져나가게 되어 있다.On the other hand, an oil passage 1a is formed inside the input shaft 1 so that oil is supplied between the third gear 21 and the hub gear 12 through the oil hole 1b, and the oil is the hub gear 12. And the clutch gear 14 is supplied to the periphery of the synchronizer ring 15 to exit outward.

그러나 상기 이비력 샤프트(1)의 오일 통로(1a)를 통해 동기 장치(10) 내부로 들어오는 오일에는 쇳가루 등의 슬러지(Sludge)가 섞여 있게 되나 이를 제거할 수 있는 별다른 구조가 이루어져 있지 않기 때문에 그대로 클러치 기어(14)와 싱크로나이저 링(15) 사이로 공급되면서 오일 속의 슬러지로 인해 심한 소음이 발생되거나 접촉부에 과다 마모를 발생시켜 결국 내구성을 저하시키는 문제점이 발생되었다.However, the oil coming into the synchronizing device 10 through the oil passage 1a of the erosion shaft 1 is mixed with sludge such as powder, but since it is not made to remove the structure, it is intact. While being supplied between the clutch gear 14 and the synchronizer ring 15, severe noise is generated due to sludge in the oil, or excessive wear occurs at the contact portion, resulting in a problem of lowering durability.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 3단 기어측의 클러치 기어 콘부 저면을 내측 방향으로 경사지게 형성시켜 이 경사부에 오일 속의 슬러지가 퇴적되게 함으로써 동기 장치의 내구성이 향상되도록 한 수동 변속기의 슬러지 제거형 윤활 구조를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the clutch gear cone portion of the third gear side is formed to be inclined inwardly so that sludge in oil is deposited on the inclined portion to improve durability of the synchronous device. To provide a sludge removing lubrication structure of the transmission.

상기한 과제를 실현하기 위한 본 발명의 수동 변속기의 슬러지 제거형 윤활구조는, 슬리이브 이동시 싱크로나이저 링이 밀착되게 콘부가 형성되는 동시에 변속 기어에 결합되어 있는 클러치 기어와, 허브 기어와 변속 기어 사이를 통해 상기 클러치 기어 내측면으로 오일이 유입되게 오일홀이 형성된 입력 샤프트가 포함된 수동 변속기에 있어서, 상기 입력 샤프트를 통해 유입되는 오일이 상기 클러치 기어의 내면에 부딪히면서 오일 흐름에 저항이 발생되어 슬러지가 퇴적될 수 있도록 상기 클러치 기어의 콘부측 저면이 끝단부로 갈수록 입력 샤프트 방향으로 일정 각도만큼 경사지게 형성된 것을 특징으로 한다.The sludge removal type lubrication structure of the manual transmission according to the present invention for realizing the above-mentioned problems includes a clutch gear which is formed at the same time the cone part is in close contact with the synchronizer ring during the movement of the sleeve, and is coupled to the transmission gear, and the hub gear and the transmission gear.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

본 발명에 의한 수동 변속기의 슬러지 제거형 윤활 구조는 도 2에 도시된 바와 같이 동기 장치(50)의 클러치 기어(62) 내면에 오일속의 슬러지가 퇴적되게 경사면(62b)이 형성되어 있다.In the sludge removing type lubrication structure of the manual transmission according to the present invention, as shown in FIG. 2, an inclined surface 62b is formed on the inner surface of the clutch gear 62 of the synchronous device 50 so that sludge in oil is deposited.

즉, 입력 샤프트(50)를 통해 윤입되는 오일이 상기 클러치 기어(62)의 내면에 부딪히면서 슬러지가 퇴적되도록 콘부(62a)측 저면이 끝단부로 갈수록 내측 방향으로 일정 각도(

Figure kpo00001
)만큼 경사지게 형성되어 있는 것이다. 여기서, 경사면(62b)의 수평방향에 대한 각도은 0°이상이면 어떤 각도라도 무방하나, 오일의 흐름을 방해하지 않도록 가급적 45°이내의 각도를 갖는 것이 좋다.That is, as the oil injected through the input shaft 50 strikes the inner surface of the clutch gear 62 and the sludge is deposited, the bottom surface of the cone portion 62a toward the end portion has a predetermined angle (
Figure kpo00001
It is inclined as much as). Here, the angle of the inclined surface 62b with respect to the horizontal direction may be any angle as long as it is 0 ° or more, but it is preferable to have an angle of 45 ° or less so as not to disturb the flow of oil.

따라서 상기 경사면(62b)은 수평 방향으로부터 어느 정도 경사지게 형성되어 오일 흐름에 대한 약간의 저항이 형성되도록 함으로써 오일 속에 포함된 슬러지가 오일과 함께 흐르지 않고 퇴적되도록 함과 동시에 슬러지가 퇴적될 수 있는 공간을 형성하는 것이다.Therefore, the inclined surface 62b is formed to be inclined to some extent from the horizontal direction so that a slight resistance to the flow of oil is formed so that the sludge contained in the oil does not flow together with the oil and at the same time, a space in which the sludge can be deposited is formed. To form.

상기와 같이 구성되는 본 발명에 따른 수동 변속기의 슬러지 제거형 윤활 구조의 작용을 설명하면 다음과 같다.Referring to the operation of the sludge removal type lubrication structure of the manual transmission according to the present invention configured as described above are as follows.

변속기의 입력 샤프트(50)의 오일 통로(50a) 및 오일 홀(50b)을 통해 변속기어인 3단 기어(61)와 허브 기어(63)사이로 유입된 오일은 원심력에 의해 클러치 기어(62)의 콘부(62a) 저면인 경사면(62b)에 부딪히게 되고, 이어 경사면을 따라 흘러서 3단 기어측으로 흐르게 된다. 이때, 경사면(62b)으로 인해 오일의 유속은 느려지게 되며, 그에 따라 오일 속에 섞여 있는 슬러지가 클러치 기어(62)의 경사면 (62b)에 퇴적된다.The oil flowing between the third gear 61 and the gear gear 63, which are the transmission gears, through the oil passage 50a and the oil hole 50b of the input shaft 50 of the transmission is the cone portion of the clutch gear 62 by centrifugal force. 62a hits the inclined surface 62b, which is the bottom surface, and then flows along the inclined surface to the third gear side. At this time, the flow rate of the oil is slowed due to the inclined surface 62b, and the sludge mixed in the oil is deposited on the inclined surface 62b of the clutch gear 62.

여기서, 상기 경사면(62b)의 각도는 0°이상이면 어떤 각도라도 오일 흐름에 대하여 저항을 주게 되므로 상관이 없으나, 경사면(62b)의 각도가 너무 클 경우에는 오일의 정상적인 흐름을 방해할 수 있으므로, 45°정도로 제한을 두는 것이 바람직하다.If the angle of the inclined surface 62b is greater than or equal to 0 °, it does not matter because any angle gives resistance to oil flow, but if the angle of the inclined surface 62b is too large, it may interfere with the normal flow of oil. It is desirable to limit it to about 45 °.

슬러지의 일부가 퇴적되어 비교적 깨끗해진 오일은 싱크로나이저 링(65)과 슬리이브(64) 사이로 빠져나가거나 싱크로나이저 링(65)과 클러치 기어(62)사이로 유동되면서 윤활 작용을 한 다음 외측으로 빠져나가게 된다.Part of the sludge deposited and relatively clean oil flows out between the synchronizer ring 65 and the sleeve 64 or lubricates as it flows between the synchronizer ring 65 and the clutch gear 62 and then outward. Will go out.

결과적으로 슬러지의 일부가 제거되어 깨끗해진 상태의 오일이 상기 싱크로나이저 링(65)과 클러치 기어(62) 사이로 유동하게 되므로 상호 접촉시 윤활성능이 향상되게 된다.As a result, part of the sludge is removed and the oil in a clean state flows between the synchronizer ring 65 and the clutch gear 62, so that the lubrication performance is improved upon mutual contact.

상기와 같은 본 발명의 수동 변속기의 슬러지 제거형 윤활 구조는 클러치 기어 내면에 형성된 경사면에 슬러지가 어느 정도 퇴적되어 비교적 깨끗한 오일이 마찰 접동 부위에 공급되게 되므로 윤활성능이 향상되어 소음 발생이 줄어들고 내구성도 향상되는 이점이 있다.The sludge removal type lubrication structure of the manual transmission of the present invention as described above has a certain amount of sludge deposited on the inclined surface formed on the inner surface of the clutch gear, so that relatively clean oil is supplied to the friction sliding portion, so that lubrication performance is improved, noise is generated, and durability There is an advantage to be improved.
