본 발명은 자동변속기 오일 냉각장치에 관한 것으로, 보다 상세하게는 냉각수의 온도에 따라 변속기 오일의 흐름을 제어하여 냉각성능을 향상시키고 변속기가 과열되는 것을 방지할 수 있는 자동변속기 오일 냉각장치에 관한 것이다. The present invention relates to an automatic transmission oil cooler, and more particularly, to an automatic transmission oil cooler capable of controlling the flow of transmission oil according to the temperature of the cooling water to improve cooling performance and to prevent the transmission from overheating. .

도 1은 종래 기술에 따른 자동변속기 오일 냉각장치의 구성도이다.1 is a block diagram of an automatic transmission oil cooling apparatus according to the prior art.

종래 기술에 따른 자동변속기 오일 냉각장치는 자동변속기(110)에서 배출되는 오일이 유입되어 공랭식으로 오일을 냉각시키는 공랭식 오일쿨러(112)와, 상기 공랭식 오일쿨러(112)를 통과하면서 1차로 냉각된 오일을 다시 수냉식으로 냉각시키는 수냉식 오일쿨러(114)로 구성된다. The automatic transmission oil cooling device according to the related art is an air cooled oil cooler 112 that cools oil in an air-cooled manner by introducing oil discharged from the automatic transmission 110, and is cooled primarily while passing through the air-cooled oil cooler 112. It is composed of a water-cooled oil cooler 114 for cooling the oil again by water-cooling.

상기 자동변속기(110)와 공랭식 오일쿨러(112) 사이는 제1유로(116)로 연결되고, 상기 제1유로(116)에는 자동변속기(110)에서 나오는 오일온도를 측정하는 제1온도센서(130)가 설치된다. 그리고, 상기 공랭식 오일쿨러(112)와 수냉식 오일쿨러(114) 사이는 제2유로(118)로 연결되고 상기 제2유로(118)에는 공랭식 오일쿨러를 통과하면서 냉각된 오일의 온도를 측정하는 제2온도센서(132)가 설치된다. 상기 수냉식 오일쿨러(114)에는 냉각수 온도를 측정하는 제3온도센서(134)가 설치된다. 그리고, 상기 수냉식 오일쿨러(114)와 자동변속기(110) 사이는 제3유로(120)로 연결되고 상기 제3유로(120)에는 제3유로(120)를 통과하는 오일의 온도를 측정하는 제4온도센서(134)가 설치된다.Between the automatic transmission 110 and the air-cooled oil cooler 112 is connected to the first passage 116, the first passage 116, the first temperature sensor for measuring the oil temperature from the automatic transmission 110 ( 130) is installed. And, the air-cooled oil cooler 112 and the water-cooled oil cooler 114 is connected to the second passage 118, the second passage 118 is a second measuring the temperature of the cooled oil while passing through the air-cooled oil cooler 2 temperature sensor 132 is installed. The water-cooled oil cooler 114 is provided with a third temperature sensor 134 for measuring the coolant temperature. In addition, the third cooling path between the water-cooled oil cooler 114 and the automatic transmission 110 is connected to the third passage 120, and the third passage 120 measures the temperature of the oil passing through the third passage 120. Four temperature sensors 134 are installed.

이와 같은 종래 기술에 따른 자동 변속기 오일 냉각장치는 자동변속기(110)에서 배출되는 오일이 제1유로(116)를 통해 공랭식 오일쿨러(112)로 유입되어 1차로 냉각되고, 1차 냉각된 오일은 제2유로(118)를 통해 수냉식 오일쿨러(114)로 유입되어 냉각수와 열교환되어 2차 냉각된다. 그리고 2차 냉각이 완료된 오일은 제3유로(120)를 통해 다시 자동변속기로 유입된다. In the automatic transmission oil cooling device according to the prior art, the oil discharged from the automatic transmission 110 flows into the air-cooled oil cooler 112 through the first flow path 116 and is cooled first, and the first cooled oil is The water flows into the water-cooled oil cooler 114 through the second flow path 118 and is heat-exchanged with the cooling water to be secondarily cooled. In addition, the oil of which the second cooling is completed is introduced into the automatic transmission again through the third passage 120.

여기에서, 상기 수냉식 오일쿨러(114)는 변속기를 보호하기 위한 변속기 오일을 냉각시키는 작용 이외에도 엔진을 냉각시키는 작용을 하므로 냉각수 온도를 일정이하로 유지해야 한다.Here, since the water-cooled oil cooler 114 functions to cool the engine in addition to cooling the transmission oil for protecting the transmission, the water temperature of the cooling water must be kept below a certain level.

그러나, 상기 수냉식 오일쿨러(114)의 냉각수 온도가 설정치 이상으로 상승되거나, 상기 수냉식 오일쿨러(114)의 냉각수 온도가 한계 냉각수온까지 근접하고, 상기 공랭식 오일쿨러(112)에서 토출되는 오일온도가 상기 자동변속기(110)로 유입되는 오일온도보다 높으면 상기 수냉식 오일쿨러(114)의 냉각수온은 한계값을 초과하게 된다. However, the coolant temperature of the water-cooled oil cooler 114 is raised above a set value, or the coolant temperature of the water-cooled oil cooler 114 is approached to a limit coolant temperature, and the oil temperature discharged from the air-cooled oil cooler 112 is increased. If it is higher than the oil temperature flowing into the automatic transmission 110, the cooling water temperature of the water-cooled oil cooler 114 exceeds the limit value.

따라서 상기 수냉식 오일쿨러(114)를 통과하는 오일온도 때문에 상기 수냉식 오일쿨러(114)의 냉각수온이 점차 높아지게 되고, 결국 오버 플로우가 발생된다. Therefore, due to the oil temperature passing through the water-cooled oil cooler 114, the cooling water temperature of the water-cooled oil cooler 114 is gradually increased, and eventually overflow occurs.

이와 같은 종래의 폐회로 시스템으로 냉각수를 냉각시키는 방법은 수냉식 오일쿨러의 방열량을 늘리는 방법으로 해결해야 되는 데, 이 경우 제조비용이 증가되는 문제점이 발생된다. The conventional method of cooling the cooling water in a closed circuit system has to be solved by increasing the heat dissipation amount of the water-cooled oil cooler. In this case, the manufacturing cost increases.

도 2는 본 발명에 따른 자동변속기 오일 냉각장치의 구성도이다.2 is a block diagram of an automatic transmission oil cooling device according to the present invention.

상기 제1라인(20)과 제3라인(24) 사이에는 상기 자동변속기(10)에서 배출되는 오일을 상기 수냉식 오일쿨러(14)로 유입시키도록 바이패스시키는 제1바이패스 라인(30)과, 상기 공랭식 오일쿨러(12)를 통과한 오일을 상기 제3라인(24)으로 바이패스시켜 상기 자동변속기(10)로 유입되도록 하는 제2바이패스 라인(32)이 각각 연결된다.A first bypass line 30 which bypasses the oil discharged from the automatic transmission 10 to the water-cooled oil cooler 14 between the first line 20 and the third line 24; Second bypass lines 32 for bypassing the oil passing through the air-cooled oil cooler 12 to the third line 24 to be introduced into the automatic transmission 10 are connected to each other.

그리고, 상기 제2라인(22)과 제3라인(24) 사이에는 상기 공랭식 오일쿨러(12)를 통과하면서 1차 냉각된 오일이 상기 수냉식 오일쿨러(14)를 통과하지 못하도록 바이패스시키는 제3바이패스 라인(34)이 연결된다.And, between the second line 22 and the third line 24 to pass the air-cooled oil cooler 12, the third to bypass the primary cooling oil does not pass through the water-cooled oil cooler 14 Bypass line 34 is connected.

상기 제1라인(20)에는 상기 자동변속기(10)에서 나오는 오일의 온도를 측정하는 제1온도센서(50)가 설치되고, 상기 제2라인(22)에는 상기 공랭식 오일쿨러(12)를 통과한 오일의 온도를 측정하는 제2온도센서(52)가 설치되고, 상기 수냉식 오일쿨러(14)에는 상기 수냉식 오일쿨러(14)를 순환하는 냉각수의 온도를 측정하는 제3온도센서(54)가 설치되고, 상기 제3라인(24)에는 상기 수냉식 오일쿨러(14)를 통과한 오일의 온도를 측정하는 제4온도센서(56)가 설치된다.The first line 20 is installed with a first temperature sensor 50 for measuring the temperature of the oil coming from the automatic transmission 10, the second line 22 passes through the air-cooled oil cooler 12 A second temperature sensor 52 for measuring the temperature of one oil is installed, and the third water sensor 54 for measuring the temperature of the cooling water circulating in the water-cooled oil cooler 14 is installed in the water-cooled oil cooler 14. The third line 24 is provided with a fourth temperature sensor 56 for measuring the temperature of the oil passing through the water-cooled oil cooler 14.

상기한 바와 같이 구성되는 본 발명에 따른 자동변속기 오일냉각장치의 작용을 다음에서 설명한다. The operation of the automatic transmission oil cooling device according to the present invention configured as described above will be described below.

도 3 내지 도 5는 본 발명에 따른 자동변속기 오일냉각장치의 작동 상태도들이다. 3 to 5 are operation state diagrams of the automatic transmission oil cooling apparatus according to the present invention.

먼저, 수냉식 오일쿨러(14)를 순환하는 냉각수에 의해 냉각된 오일의 유온(제4온도센서(56)에서 측정된 오일 온도값)이 공랭식 오일쿨러(12)를 통과한 유온(제2온도센서(52)에서 측정된 오일 온도값)보다 낮다면 상기 공랭식 오일쿨러(12)와 상기 수냉식 오일쿨러(14) 둘 다에 의해 오일이 냉각되고 있는 것을 의미한다.First, the oil temperature (second temperature sensor) in which the oil temperature (oil temperature value measured by the fourth temperature sensor 56) of the oil cooled by the cooling water circulating through the water-cooled oil cooler 14 passes through the air-cooled oil cooler 12. Lower than the oil temperature measured at 52, it means that the oil is being cooled by both the air-cooled oil cooler 12 and the water-cooled oil cooler 14.

이러한 경우 도 3에 도시된 바와 같이, 자동변속기(10)에서 배출되는 오일이 제1라인(20)을 통해 공랭식 오일쿨러(12)를 통과하면서 1차로 냉각되고, 1차 냉각이 완료된 오일은 제2라인(22)을 통해 수냉식 오일쿨러(14)로 유입되어 냉각수에 의해 2차로 냉각되고, 제3라인(24)을 통해 상기 자동 변속기(10)로 유입된다.In this case, as shown in FIG. 3, the oil discharged from the automatic transmission 10 is first cooled while passing through the air-cooled oil cooler 12 through the first line 20, and the oil having the first cooling is finished. It is introduced into the water-cooled oil cooler 14 through the second line 22 and secondly cooled by the cooling water, and is introduced into the automatic transmission 10 through the third line 24.

그리고, 공랭식 오일쿨러(12)를 통과하면서 냉각된 유온이 수냉식 오일쿨러(14)의 냉각수의 온도보다 낮거나 같을 경우에는 도 4에 도시된 바와 같이, 제1 및 제2바이패스 통로(30,32)를 통해 바이패스되어 먼저 수냉식 오일쿨러(14)에서 1차로 냉각되고, 공랭식 오일쿨러(12)에서 2차로 냉각된다. When the oil temperature cooled while passing through the air-cooled oil cooler 12 is lower than or equal to the temperature of the cooling water of the water-cooled oil cooler 14, as shown in FIG. 4, the first and second bypass passages 30, It is bypassed through 32 and is first cooled in the water-cooled oil cooler 14 and secondly in the air-cooled oil cooler 12.

일예로, 제1온도센서(50)에서 측정된 오일온도가 128℃이고, 제2온도센서(52)에 측정된 오일온도가 120℃이고, 제3온도센서(54)에서 측정된 냉각수의 온도가 126℃이고, 제4온도센서(56)에 측정된 오일온도가 123℃일 경우, 최초 자동변속기(10)에서 배출되는 오일이 공랭식 오일쿨러(12)를 통과하면서 8℃의 냉각효과를 보게 되어 120℃고, 수냉식 오일쿨러(14)의 냉각수와 열교환되면서 최종적으로 자동변속기(10)로 유입되는 오일온도는 123℃가 된다.For example, the oil temperature measured by the first temperature sensor 50 is 128 ° C., the oil temperature measured by the second temperature sensor 52 is 120 ° C., and the temperature of the coolant measured by the third temperature sensor 54. Is 126 ° C. and the oil temperature measured by the fourth temperature sensor 56 is 123 ° C., the oil discharged from the first automatic transmission 10 passes through the air-cooled oil cooler 12 and has a cooling effect of 8 ° C. The temperature of the oil introduced into the automatic transmission 10 is 123 ° C while being heat exchanged with the cooling water of the water-cooled oil cooler 14.

하지만, 도 4에 도시된 바와 같이, 오일의 순환로를 전환시키면 자동변속기(10)에서 배출되는 128℃의 오일은 제1바이패스 라인(30)를 통해 수냉식 오일쿨러(14)의 냉각수와 열교환되면서 127℃가 되고, 다시 공랭식 오일쿨러(12)를 통과하면서 8℃의 냉각효과를 보게 되어 최종적으로 119℃의 오일이 제2바이패스 라인(32)를 통해 자동변속기(10)로 유입된다.However, as shown in FIG. 4, when the oil circulation path is switched, the oil having 128 ° C. discharged from the automatic transmission 10 is exchanged with the cooling water of the water-cooled oil cooler 14 through the first bypass line 30. At 127 ° C., the cooling air passes through the air-cooled oil cooler 12, and the cooling effect is 8 ° C., and finally, the oil at 119 ° C. flows into the automatic transmission 10 through the second bypass line 32.

이와 같이, 기존 오일온도 123℃에 비해 오일온도를 4℃ 정도 낮출 수 있어 냉각효과를 향상시킬 수 있게 된다. Thus, the oil temperature can be lowered by about 4 ℃ compared to the existing oil temperature 123 ℃ can improve the cooling effect.

그리고, 제3온도센서(54)에서 측정된 냉각수의 온도가 설정치 이상으로 상승되면 도 5에 도시된 바와 같이, 오일을 제3바이패스 통로(34)를 통해 바이패스시켜 수냉식 오일쿨러(14)를 통과하지 않도록 하여 엔진이 과열되는 것을 방지한다. Then, when the temperature of the coolant measured by the third temperature sensor 54 rises above the set value, as shown in FIG. 5, the oil is bypassed through the third bypass passage 34 to cool the water-cooled oil cooler 14. Do not pass through the engine to prevent overheating.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 자동변속기의 오일냉각장치는 냉각수의 온도에 따라 수냉식 오일쿨러와 공랭식 오일쿨러의 오일이 통과하는 순서를 변화시켜 냉각성능을 향상시킬 수 있는 이점이 있다.Therefore, the oil cooling apparatus of the automatic transmission according to the present invention configured and operated as described above has an advantage of improving the cooling performance by changing the order of passing the oil of the water-cooled oil cooler and the air-cooled oil cooler according to the temperature of the cooling water. have.

또한, 수냉식 오일쿨러의 냉각수 온도가 설정온도 이상으로 초과하게 되면 오일이 수냉식 오일쿨러로 유입되지 않도록 바이패스시켜 엔진이 과열되는 것을 방지할 수 있다. In addition, when the cooling water temperature of the water-cooled oil cooler exceeds the set temperature or more, the engine may be prevented from being overheated by bypassing oil so as not to flow into the water-cooled oil cooler.
