본 고안은 자동변속기의 오일 배출구조에 관한 것으로, 더욱 상세하게는 오일 펌프작동시 누출된 오일을 신속히 자동 변속기내로 배출하고 오일펌프의 조립을 용이하게 할 수 있는 자동 변속기의 오일 배출구조에 관한 것이다.The present invention relates to an oil discharge structure of an automatic transmission, and more particularly, to an oil discharge structure of an automatic transmission that can quickly discharge oil leaked during operation of the oil pump into the automatic transmission and facilitate assembly of the oil pump. .

차량의 속도를 변화시키는 변속기에는 운전자가 직접 각 변속단을 선택함에 따라 변속이 수행되는 수동변속기와, 통상적으로 유체 토크 컨버터와 유성기어 장치를 조합하여 유압제어 시스템에 의해 운전조건과 엔진의 부하에 따라 자동적으로 변속이 이루어지는 자동변속기가 있다.In the transmission that changes the speed of the vehicle, a manual transmission in which the shift is performed by the driver directly selecting each gear stage, and a combination of a fluid torque converter and a planetary gear device are usually used to control the driving conditions and the load of the engine by a hydraulic control system. There is an automatic transmission that automatically shifts accordingly.

현재에는 자동차 산업의 발달과 더불어 조작이 간편한 자동변속기의 사용이 증대되고 있으며, 특히 교통환경이 날로 열악해지는 대도시에서는 전 차종에 걸쳐 그 사용이 더욱 확대되고 있다. 이러한 자동변속기의 사용이 증가되는 추세에 따라 오일 흐름에 대한 많은 구조적인 개선이 이루어지고 있는 실정이지만, 오일의 배출 구조상 수반되는 오일 누출의 문제는 여전히 남아 있다.Nowadays, with the development of the automobile industry, the use of automatic transmissions that are easy to operate is increasing, especially in large cities where the traffic environment is poor. As the use of such automatic transmissions increases, many structural improvements to the oil flow have been made, but the problem of oil leakage accompanying the oil discharge structure still remains.

종래의 오일 배출구조가 지닌 문제점을 알아보기 위해 제1도를 참조하여 자동변속기의 개략적인 구조를 살펴보기로 한다.In order to find out the problems with the conventional oil discharge structure, a schematic structure of an automatic transmission will be described with reference to FIG. 1.

제1도에는 통상적인 자동변속기의 일부를 단면 도시하였다. 대략적으로 자동변속기는 엔진이 회전하면 펌프 임펠러내의 오일이 원심력에 의해 터빈 러너를 회전시킴으로써 회전력을 변환시키는 토크 컨버터(도시 않음)와, 유성기어 및 그것을 조작하는 클러치(8, 9, 10)와 브레이크 밴드(12)로 구성되어 토크 컨버터의 회전력을 출력축에 전달 및 차단하는 유성기어 장치와, 차속이나 운전조건에 맞추어 자동으로 유압을 변환하여 유성기어장치를 조작하는 유압제어기구로 구성된다.1 is a cross-sectional view of a portion of a typical automatic transmission. In general, the automatic transmission includes a torque converter (not shown) in which oil in the pump impeller rotates the turbine runner by centrifugal force when the engine rotates, and a planetary gear and clutches (8, 9, 10) and brakes that operate the engine. It consists of a band 12, the planetary gear device for transmitting and blocking the rotational force of the torque converter to the output shaft, and a hydraulic control mechanism for operating the planetary gear device by automatically converting the hydraulic pressure in accordance with the vehicle speed or operating conditions.

유압제어 기구중에서 입력측에 설치된 오일펌프(2)는 엔진의 회전과 동시에 토크 컨버터에 오일을 공급하고 컨버터의 압력을 일정하게 유지하는 역할을 한다. 또한 유성기어장치를 윤활시키며 제어시스템에 라인 압력 상태의 작동유를 공급한다.The oil pump 2 installed at the input side of the hydraulic control mechanism serves to supply oil to the torque converter and maintain the pressure of the converter at the same time as the engine rotates. It also lubricates the planetary gear units and supplies the control system with hydraulic fluid at line pressure.

제2도에 확대하여 도시한 바와 같이, 종래의 오일 펌프(2)의 오일 배출구조에서는 오일 펌프(2)가 고압(최대 19bar)에서 작동 되기 때문에 누출된 오일은 화살표 방향을 따라 변속기 케이스(4) 밖으로 배출될 우려가 있다.As enlarged in FIG. 2, in the oil discharge structure of the conventional oil pump 2, since the oil pump 2 is operated at a high pressure (up to 19 bar), the leaked oil is transferred to the transmission case 4 along the direction of the arrow. ) It may be discharged outside.

따라서 이러한 종래의 자동변속기의 오일 배출구조에서는 오일펌프에서 누출된 오일이 자동변속기의 외부로 배출된다고 하는점 이외에도 오일펌프의 분해 조립시에 작업성이 나쁘다고 하는 문제점이 있다.Therefore, in the oil discharge structure of the conventional automatic transmission, in addition to the fact that the oil leaked from the oil pump is discharged to the outside of the automatic transmission, there is a problem in that workability is poor at the time of disassembly and assembly of the oil pump.

이와 같은 문제점을 감안한 본 고안의 목적은 오일펌프에서 누출된 오일을 신속하게 자동변속기내로 배출시킬 수 있고, 오일펌프의 자동변속기 케이스로부터의 탈착시 조립 및 분해가 용이한 오일 배출구조를 제공하는데 있다.It is an object of the present invention in view of the above problems to provide an oil discharge structure that can quickly discharge oil leaked from an oil pump into an automatic transmission, and is easy to assemble and disassemble when the oil pump is detached from an automatic transmission case. .

상술한 목적을 달성하기 위해 본 고안은 펌프 임펠러와 함께 차량의 엔진에 의해 구동되며 토오크 컨버터와 유압제어장치 및 각 윤활부로 각 오일을 공급하는 오일 펌프와 변속기 케이스간에 형성되는 자동변속기의 오일 배출구조에 있어서, 상기 오일펌프의 하우징에는 단부가 형성되어 있고, 상기 변속기 케이스는 상기단부에 누출된 오일을 포집하는 모서리부와, 상기 모서리부에 포집된 오일을 오일팬으로 보내는 오일 배출통로를 구비하는 것을 특징으로 하는 자동변속기의 오일 배출구조를 제공한다.In order to achieve the above object, the present invention is driven by an engine of a vehicle together with a pump impeller, and an oil discharge structure of an automatic transmission is formed between an oil pump and a transmission case supplying oil to a torque converter, a hydraulic control device, and each lubrication unit. In the housing of the oil pump is formed with an end, the transmission case is provided with an edge portion for collecting the oil leaked at the end, and the oil discharge passage for sending the oil collected in the corner portion to the oil pan It provides an oil discharge structure of an automatic transmission, characterized in that.

다음에는 첨부한 제3도 내지 제4도를 참조하여 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Next, a preferred embodiment of the present invention will be described in detail with reference to FIGS. 3 to 4.

제3도는 본 고안에 따른 오일펌프(10)의 일부를 도시한 단면도이다. 도시한 바와 같이, 오일펌프 하우징(12)의 외주에는 단부(14)를 형성하였으며, 그에 따라 오일펌프 하우징(12)과 자동 변속기 케이스(18) 사이에는 틈새(16)가 형성된다. 따라서, 오일펌프의 작동시 고압으로 누출된 오일은 변속기 케이스(18) 외부로 누출되지 않게 된다.3 is a cross-sectional view showing a part of the oil pump 10 according to the present invention. As shown, the end portion 14 is formed on the outer circumference of the oil pump housing 12, and thus a gap 16 is formed between the oil pump housing 12 and the automatic transmission case 18. Therefore, the oil leaked at high pressure during the operation of the oil pump does not leak outside the transmission case 18.

또한, 오일펌프 조립체의 조립 및 분해시에는 일정한 크기의 틈새(16)가 존재하므로 오일펌프 조립체(10)와 변속기 케이스(18)간의 접촉면적이 감소되어 조립 및 분해가 용이하게 된다.In addition, when assembling and disassembling the oil pump assembly, a gap 16 having a predetermined size exists so that the contact area between the oil pump assembly 10 and the transmission case 18 is reduced, thereby facilitating assembly and disassembly.

제4도에는 본 고안의 바람직한 실시예에 따른 자동변속기 케이스의 오일 배출통로가 단면 도시되어 있으며, 간략히 도시하기 위해 변속기 케이스(18)는 일부만을 나타내었다.Figure 4 is a cross-sectional view of the oil discharge passage of the automatic transmission case according to a preferred embodiment of the present invention, the transmission case 18 is shown only a portion for the sake of simplicity.

제4도에 나타낸 바와 같이 자동변속기 케이스(18)는 둥근 형상의 모서리부(20)를 지니며, 이 모서리부(20)와 연결되는 오일 배출통로(22)가 형성되어 있다. 따라서, 누출된 오일은 모서리부(20)에 포집된 후 오일배출통로(22)를 통해 자동변속기의 오일을 저장하는 오일팬(도시하지 않음)으로 배출된다.As shown in FIG. 4, the automatic transmission case 18 has a rounded corner 20, and an oil discharge passage 22 connected to the corner 20 is formed. Therefore, the leaked oil is collected in the corner portion 20 and then discharged through an oil discharge passage 22 to an oil pan (not shown) that stores the oil of the automatic transmission.

이와 같이 구성된 본 고안의 오일배출 구조에 의하면 오일펌프에서 누출된 오일이 외부로 배출되지 않고 오일팬내로 전달됨과 동시에 오일펌프의 조립 및 분해가 용이한 자동변속기의 오일배출구조를 제공할 수 있다.According to the oil discharge structure of the present invention configured as described above, it is possible to provide an oil discharge structure of an automatic transmission in which oil leaked from an oil pump is delivered to the oil pan without being discharged to the outside and the oil pump can be easily assembled and disassembled.
