본 발명은 하이브리드 자동차용 통합 펌프에 관한 것으로, 더욱 상세하게는 하이브리드 자동차의 쿨링펌프와 오일펌프를 일체화하여 원가 및 중량을 절감하고 엔진룸 내부의 공간 활용성을 향상시킨 하이브리드 자동차용 통합 펌프에 관한 것이다.The present invention relates to an integrated pump for a hybrid vehicle, and more particularly, to an integrated pump for a hybrid vehicle in which a cooling pump and an oil pump of a hybrid vehicle are integrated to reduce cost and weight and improve space utilization in an engine room. will be.

일반적으로 하이브리드 자동차는 가솔린으로 구동되는 내연 엔진에 고전압 배터리를 추가로 장착하여 가솔린 엔진의 연비가 떨어지는 초기 시동 구간이나 아이들 스탑(Idle Stop) 시 배터리에 의해 차량이 구동될 수 있도록 하는 구조이다.In general, a hybrid vehicle has a structure in which a vehicle is driven by a battery during an initial start section or idle stop where fuel economy of a gasoline engine is reduced by additionally installing a high voltage battery in an internal combustion engine driven by gasoline.

이러한 하이브리드 자동차의 엔진룸 내 장착되는 부품의 대부분은 전장류로써 열에 민감하게 반응하기 때문에 고온의 엔진룸 내에서 원활한 동작을 하기 위해 일정 온도 이하의 상태로 유지시키는 것이 중요하다. 따라서 하이브리드용 부품이 작동하는 초기 EV 모드(Electric Vehicle Mode) 및 아이들 스탑(Idle STop)시 뿐만 아니라 엔진이 재가동하여 엔진룸 내부의 온도가 상승하는 정상 주행(가솔린으로만 주행)시에도 하이브리드용 부품의 냉각이 필요하다. 종래에는 이러한 하이브리드용 부품의 냉각을 위해 별도의 쿨링펌프를 사용하였다.Since most of the components mounted in the engine room of such a hybrid vehicle are electric components sensitive to heat, it is important to keep the temperature below a certain temperature for smooth operation in a high temperature engine room. Therefore, not only during the initial EV mode and idle stop, where the hybrid parts operate, but also during normal driving (driving only with gasoline) when the engine is restarted and the temperature inside the engine room rises. Cooling is required. In the related art, a separate cooling pump was used to cool such hybrid components.

또한, 하이브리드 자동차의 초기 시동 구간 즉, 일정 속도 이하로 운전하여 가솔린 엔진이 작동되지 않고 배터리에 의해 차량이 구동되는 EV 모드 및 아이들 스탑시 엔진이 정지 상태이므로 자동변속기 내부에 장착된 기계식 오일펌프의 동작도 멈추게 된다. 그런데 기계식 오일펌프의 동작이 멈추더라도 자동 변속기 내의 언더 브레이크(Under Brake) 제어압과 변속기 내의 쿨링 및 윤활유의 공급을 위해 별도의 전동식 오일펌프를 사용하였다.In addition, since the EV mode in which the gasoline engine is not operated by driving below the predetermined speed, that is, the vehicle is driven by the battery, and the engine is stopped when the idle stop is stopped, the mechanical oil pump mounted inside the automatic transmission It will also stop working. However, even when the operation of the mechanical oil pump stopped, a separate electric oil pump was used for supplying the under brake control pressure in the automatic transmission and cooling and lubricating oil in the transmission.

그런데 이러한 종래의 하이브리드 자동차에 있어서, 쿨링펌프와 오일펌프를 각각 별도로 장착하여 사용해야하므로 설치에 필요한 점유 공간이 확대될 뿐만 아니라 각각의 펌프 조립시 별개로 작업해야 하는 불편함이 있다. 또한, 엔진룸 내부의 공간 활용성이 저하되고, 라인 작업시 작업시간이 길어지는 문제가 있다.However, in such a conventional hybrid vehicle, since the cooling pump and the oil pump must be separately installed and used, the occupied space required for installation is expanded, and there is an inconvenience of having to work separately when assembling each pump. In addition, there is a problem that the space utilization inside the engine room is lowered, and the working time is long during the line work.

본 발명의 목적은 항상 구동하는 쿨링펌프와 조건에 따라 일시적으로 작동하는 전동식 오일펌프의 구동축을 공유하여 일체화시킨 하이브리드 자동차용 통합 펌프를 제공함으로써 원가 및 중량을 절감하고 엔진룸 내부의 공간 활용성을 향상시키는 것이다.An object of the present invention is to provide an integrated pump for a hybrid vehicle which is integrated by sharing the driving shaft of the always-driven cooling pump and the electric oil pump that is temporarily operated according to the conditions to reduce the cost and weight and to utilize the space utilization inside the engine room To improve.

도 1을 참조하여 본 발명의 하이브리드 자동차에 따른 신호체계와 냉각수 공급체계 및 변속기 오일 공급체계를 살펴보면 다음과 같다.Referring to Figure 1 with reference to the signal system, the cooling water supply system and the transmission oil supply system according to the hybrid vehicle of the present invention.

하이브리드 컨트롤 유닛(70)이 각종 센서(60)로부터 엔진의 구동 상태나 차량의 속도 등과 같은 차량의 상태를 파악하여 모터 컨트롤 유닛(80)에 차량의 제어를 위한 명령을 내리면, 모터 컨트롤 유닛(80)이 ISG(30)와 모터, 통합 인버터(50) 등에 제어신호를 보내고, 통합 인버터(50)를 통해 펌프 컨트롤러(105)에도 제어 신호가 전달된다. 이러한 신호를 바탕으로 통합 펌프(100)가 작동하여 쿨링펌프(110) 와 오일펌프(140)가 동시에 구동하거나 쿨링펌프(110)만 구동하도록 제어된다.When the hybrid control unit 70 detects the state of the vehicle such as the engine driving state or the speed of the vehicle from various sensors 60 and gives the motor control unit 80 a command for controlling the vehicle, the motor control unit 80 ) Sends a control signal to the ISG 30, the motor, the integrated inverter 50, and the like, and the control signal is also transmitted to the pump controller 105 through the integrated inverter 50. Based on this signal, the integrated pump 100 operates to control the cooling pump 110 and the oil pump 140 to be driven at the same time or to drive only the cooling pump 110.

엔진(10)과 모터 및 변속기(20)를 냉각하고 온도가 상승한 상태로 배출되는 냉각수는 ISG(30)를 거쳐 라디에이터(40)로 보내져 열교환이 이루어지고, 다시 차가워진 냉각수는 통합 인버터(50)를 거쳐 리저버(90)로 이송되어 저장된다. 리저버(90)에 저장된 냉각수는 통합 펌프(100)의 쿨링펌프(110)를 통해 다시 모터를 냉각하도록 공급된다.Cooling water that cools the engine 10, the motor and the transmission 20, and is discharged while the temperature is raised is sent to the radiator 40 via the ISG (30) to perform heat exchange, and the coolant cooled again is an integrated inverter (50) It is transferred to the reservoir 90 via the stored. The coolant stored in the reservoir 90 is supplied to cool the motor again through the cooling pump 110 of the integrated pump 100.

변속기로 공급되는 작동 및 윤활 오일은 본 발명의 하이브리드 자동차가 초기 구동시 EV 모드(Electric Vehicle mode)로 운행되거나 아이들 스탑(Idle Stop)시 통합 펌프(100) 내의 전동식 오일펌프(140)에 의해 공급되고, 엔진(10)이 작동하여 가솔린만으로 주행시에는 변속기(20) 내의 기계식 오일펌프(22)에 의해 공급된다.The operating and lubricating oil supplied to the transmission is supplied by the electric oil pump 140 in the integrated pump 100 when the hybrid vehicle of the present invention is driven in an electric vehicle mode at an initial driving or idle stop. When the engine 10 operates and runs only with gasoline, the engine 10 is supplied by the mechanical oil pump 22 in the transmission 20.

도 2 내지 도 4를 참조하여 본 발명의 통합 펌프(100)를 살펴보면, 통합 펌프(100)는 냉각수를 순환시키기 위한 쿨링펌프(110)와, 쿨링펌프(110)를 구동하기 위한 구동축(120)이 구비된 펌프 모터(130)와, 펌프 모터(130)에 의해 함께 작동하는 오일펌프(140)로 구성된다.Referring to the integrated pump 100 of the present invention with reference to Figures 2 to 4, the integrated pump 100 is a cooling pump 110 for circulating the cooling water, and a drive shaft 120 for driving the cooling pump 110 It is composed of a pump motor 130 and an oil pump 140 that is operated together by the pump motor 130.

펌프 모터(130)의 수밀과 기밀을 위해 통합 펌프(100)는 펌프 모터(130)의 하부에 쿨링펌프(110)와 오일펌프(140)가 순차적으로 위치하는 것이 바람직하다, 쿨링펌프(110)와 오일펌프(140)의 위치는 서로 바뀌어도 무방하다.For the watertightness and airtightness of the pump motor 130, the integrated pump 100 preferably has the cooling pump 110 and the oil pump 140 sequentially positioned below the pump motor 130, the cooling pump 110. The positions of the oil pump 140 may be interchanged with each other.

쿨링펌프(110)는 펌프 모터(130)에 연결된 구동축(120)에 의해 블로워(112)가 회전하면서 리저버(90)에 저장된 냉각수를 펌핑하여 모터와 ISG(30), 통합 인버 터(50) 등으로 순환시킨다. 쿨링펌프(110)는 엔진(10)의 구동 여부에 상관없이 항상 작동된다. 즉, 쿨링펌프(110)는 엔진룸 내 하이브리드용 부품인 모터와 ISG(30), 통합 인버터(50) 등의 냉각을 위해 초기 EV 모드로 출발할 때나 아이들 스탑시 엔진(10)의 정지 상태뿐만 아니라 엔진(10)의 재가동시에도 항상 구동하도록 제어된다.The cooling pump 110 pumps the coolant stored in the reservoir 90 while the blower 112 is rotated by the drive shaft 120 connected to the pump motor 130, so that the motor, the ISG 30, the integrated inverter 50, etc. Circulate The cooling pump 110 is always operated regardless of whether the engine 10 is driven. That is, the cooling pump 110 is a standstill state of the engine 10 when starting from the initial EV mode or when the idle stop for cooling of the motor, the ISG 30, the integrated inverter 50, and the like, the hybrid component in the engine room. It is also controlled to always drive even when the engine 10 is restarted.

오일펌프(140)는 전동식 펌프로써, 펌프 모터(130)의 구동축(120)을 공유한다. 오일펌프(140)는 항상 구동되지 않고 차량의 초기 EV 모드 출발시나 아이들 스탑시 엔진(10)의 정지 상태에서 기계식 오일펌프(22)를 대신하여 변속기 내에 언더 브레이크(Under Brake) 제어압과 변속기(20) 내의 윤활유 공급을 위해 간헐적으로 구동된다. 이를 위해 오일펌프(140)에는 풀리(142)가 장착되고 구동축(120)에는 클러치(122)가 장착된다.The oil pump 140 is an electric pump and shares the drive shaft 120 of the pump motor 130. The oil pump 140 is not always driven, and under brake control pressure and the transmission (in the transmission) in place of the mechanical oil pump 22 at the start of the vehicle's initial EV mode or the idle stop of the engine 10. 20) is intermittently driven for lubricating oil supply. To this end, a pulley 142 is mounted on the oil pump 140 and a clutch 122 is mounted on the drive shaft 120.

클러치(122)는 전자식 클러치로써, 펌프 컨트롤러(105)가 하이브리드 컨트롤 유닛(70)으로부터 작동신호를 받아 클러치(122)에 보내면, 풀리(142)와 붙어(클러치 Closed) 오일펌프(140)가 쿨링펌프(110)의 구동축(120)을 공유하여 작동할 수 있게 한다(도 3 참조).The clutch 122 is an electronic clutch. When the pump controller 105 receives an operation signal from the hybrid control unit 70 and sends it to the clutch 122, the clutch 122 is attached to the pulley 142 (clutch closed) and the oil pump 140 is cooled. The drive shaft 120 of the pump 110 can be shared and operated (see FIG. 3).

엔진(10)이 초기 EV 모드 출발 후 소정 속도(예를 들어 5km/h) 이상으로 정상 가동하여 변속기(20) 내의 기계식 오일펌프(22)가 구동하게 되면 전동식 오일펌프(140)는 구동하지 않아도 된다. 이때는 하이브리드 컨트롤 유닛(70)이 펌프 컨트롤러(105)에 오일펌프(140)의 작동이 중지되도록 신호를 보낸다. 펌프 컨트롤러(105)는 클러치(122)가 풀리(142)로부터 떨어지도록(클러치 Open) 제어하여 오일 펌프(140)의 작동을 중지시킨다(도 4 참조).If the engine 10 is normally operated at a predetermined speed (for example, 5 km / h) or more after the initial EV mode starts, and the mechanical oil pump 22 in the transmission 20 is driven, the electric oil pump 140 does not need to be driven. do. At this time, the hybrid control unit 70 sends a signal to the pump controller 105 to stop the operation of the oil pump 140. The pump controller 105 controls the clutch 122 to be separated from the pulley 142 (clutch open) to stop the operation of the oil pump 140 (see FIG. 4).

이와 같이 쿨링펌프와 오일펌프가 일체로 형성된 통합펌프를 사용함으로써 엔진이 정지하고 EV 모드로 주행하거나 아이들 스탑시에도 변속기에 작동유가 지속적으로 공급될 수 있다. 또한, 두 개의 펌프류를 하나로 줄임으로써 라인 작업시 장착 시간이 감소되어 작업 효율이 향상되며, 부품 공유에 의한 불필요한 부품 삭제로 원가 및 중량 절감의 효과가 크고 엔진룸 내 공간을 효과적으로 활용할 수 있다.As such, by using the integrated pump in which the cooling pump and the oil pump are integrally installed, the hydraulic oil can be continuously supplied to the transmission even when the engine is stopped and the vehicle is driven in the EV mode or the idle stop is performed. In addition, by reducing two pumps to one, the installation time is reduced during line work, and work efficiency is improved, and unnecessary parts are deleted by part sharing, thereby reducing cost and weight, and effectively utilizing space in the engine room.
