Description

하이브리드 차량용 구동계 장치{POWER TRAIN APPARATUS FOR HYBRID VEHICLE}Drivetrain device for hybrid vehicle {POWER TRAIN APPARATUS FOR HYBRID VEHICLE}

본 발명은 하이브리드 차량용 구동계 장치에 관한 것이다.The present invention relates to a drivetrain device for a hybrid vehicle.

일반적으로 하이브리드 차량은 서로 다른 두 종류 이상의 동력원을 효율적으로 조합하여 차량을 구동시키는 것을 의미한다. 하이브리드 차량은 연료(가솔린 등 화석연료)를 연소시켜 회전력을 얻는 엔진과 배터리 전력으로 회전력을 얻는 모터에 의해 구동하는 차량을 의미한다.In general, a hybrid vehicle refers to driving the vehicle by efficiently combining two or more different types of power sources. A hybrid vehicle refers to a vehicle driven by an engine that obtains rotational power by burning fuel (fossil fuel such as gasoline) and a motor that acquires rotational power using battery power.

이러한 하이브리드 차량은 엔진뿐만 아니라 모터를 보조동력원으로 채택하여 배기가스 저감 및 연비 향상을 도모할 수 있는 미래형 차량으로 연구가 활발히 진행되고 있다.Such hybrid vehicles are being actively researched as a future vehicle that can reduce exhaust gas and improve fuel efficiency by adopting a motor as an auxiliary power source as well as an engine.

하이브리드 차량은 통상적으로 엔진과 모터를 사용하는데, 저속에서는 상대적으로 저속토크 특성이 좋은 모터를 주 동력원으로 사용하고, 고속에서는 상대적으로 고속토크 특성이 좋은 엔진을 주 동력원으로 사용한다. 이에 따라, 하이브리드 차량은 저속구간에서 화석 연료를 사용하는 엔진의 작동이 정지되고 모터를 사용하기 때문에 연비 개선과 배기가스의 저감에 우수한 효과가 있다.A hybrid vehicle typically uses an engine and a motor. At low speed, a motor having relatively good low-speed torque characteristics is used as a main power source, and at high speed, an engine having relatively good high-speed torque characteristics is used as a main power source. Accordingly, the hybrid vehicle has excellent effects in improving fuel efficiency and reducing exhaust gas because the engine using the fossil fuel is stopped in the low speed section and the motor is used.

하이브리드 차량용 구동장치는 구동을 위해 모터의 회전력만을 이용하는 순수 전기자동차 모드인 EV(Electric Vehicle) 모드와, 엔진의 회전력을 주동력으로 하면서 모터의 회전력을 보조동력으로 이용하는 HEV(Hybrid Electric Vehicle) 모드 등의 운전모드로 주행하며, 엔진의 시동을 통해 EV 모드에서 HEV 모드로의 모드 변환이 이루어진다.The driving device for a hybrid vehicle is an EV (Electric Vehicle) mode, which is a pure electric vehicle mode that uses only the rotational power of the motor for driving, and an HEV (Hybrid Electric Vehicle) mode that uses the rotational power of the motor as an auxiliary power while using the rotational power of the engine as the main power. driving mode, and the mode conversion from EV mode to HEV mode is made by starting the engine.

종래의 하이브리드 시스템은 고전압 시스템 대비 저렴한 부품으로 구성할 수 있으며 2개 이상의 모터 조합을 통해 단시간 동안 풀 하이브리드에 준하는 수준의 출력을 구현할 수 있다. 이러한 종래의 하이브리드 시스템은 일반적으로 모터의 위치에 따라 P0, P1, P2, P3, P4로 구분하며, 각각은 EV 모드의 구현 여부, 회생 제동 성능 등에 차이를 나타낸다.A conventional hybrid system can be composed of parts that are cheaper than a high voltage system, and can realize an output comparable to that of a full hybrid for a short time through a combination of two or more motors. Such a conventional hybrid system is generally divided into P0, P1, P2, P3, and P4 according to the position of the motor, and each represents a difference in whether the EV mode is implemented, regenerative braking performance, and the like.

도 1은 종래의 하이브리드 차량용 구동계 장치를 나타내는 도면이다. 도 1을 참조하면, 기존의 P1 타입 하이브리드 구조는, P1 모터(111)의 스테이터(111b)가 제1 하우징(116)에 지지되고, P1 모터(111)의 로터(111a)는 토션 댐퍼(120)와 일체화되어 엔진(130)과 볼팅(140) 연결된다. P1 모터(111)가 변속기와 분할되는 구조이다. P2 모터(112)의 스테이터(112b)는 제2 하우징(117)에 지지되고, P2 모터(112)의 로터(112a)는 내측의 엔진 클러치(113)를 통해 토션 댐퍼(120)와 연결된다.1 is a view showing a conventional drivetrain device for a hybrid vehicle. Referring to FIG. 1 , in the conventional P1 type hybrid structure, the stator 111b of the P1 motor 111 is supported by the first housing 116 , and the rotor 111a of the P1 motor 111 is a torsion damper 120 . ) is integrated with the engine 130 and the bolting 140 is connected. The P1 motor 111 has a structure in which the transmission is divided.

도 2, 3을 참조하면, 본 발명은 별도 냉각 장치 없이도 변속기 장치(10) 측의 윤활유를 활용하여 P1 모터(11)를 강제 냉각할 수 있다.2 and 3 , in the present invention, the P1 motor 11 can be forcibly cooled by using the lubricant on the transmission device 10 side without a separate cooling device.

엔진(30)과 P1 모터(11)와 P2 모터(12)의 출력은 변속기(14)를 통해 변속된 뒤 구동축 거쳐 구동바퀴(W)에 최종 전달된다.The outputs of the engine 30 , the P1 motor 11 , and the P2 motor 12 are shifted through the transmission 14 and finally transmitted to the driving wheel W via the drive shaft.

엔진 클러치(13)는 P1 모터(11)와 P2 모터(12) 사이에서 엔진(30) 동력의 분리 연결을 제어한다.The engine clutch 13 controls the disconnection connection of the engine 30 power between the P1 motor 11 and the P2 motor 12 .

엔진 클러치(13)에 의해 1 모터(11) 및 P2 모터(12) 사이의 동력이 끊어지면 P2 모터(12)의 회전력만을 이용하는 순수 전기자동차 모드인 EV(Electric Vehicle) 주행모드로 주행이 이루어진다.When the power between the 1 motor 11 and the P2 motor 12 is cut off by the engine clutch 13 , the driving is performed in the EV (Electric Vehicle) driving mode, which is a pure electric vehicle mode using only the rotational force of the P2 motor 12 .

엔진 클러치(13)에 의해 1 모터(11) 및 P2 모터(12) 사이의 동력이 연결되면 P1 모터(11) 및 P2 모터(12)의 회전동력과 함께 엔진(30)의 회전동력을 동시에 이용하는 HEV(Hybrid Electric Vehicle) 주행모드로 주행이 이루어진다.When the power between the 1 motor 11 and the P2 motor 12 is connected by the engine clutch 13, the rotation power of the engine 30 is simultaneously used together with the rotation power of the P1 motor 11 and the P2 motor 12. Driving is performed in HEV (Hybrid Electric Vehicle) driving mode.

초기 출발 및 저속 주행 시에는 EV 모드가 선택되어 엔진 클러치(13)가 동력연결을 끊음으로써 엔진(30)의 연결이 해제된 상태로 P2 모터(12)에 의해서만 차량 구동력을 얻게 된다.During the initial start and low-speed driving, the EV mode is selected and the engine clutch 13 cuts the power connection, so that the engine 30 is disconnected and the vehicle driving power is obtained only by the P2 motor 12 .

특히 차량의 초기 출발 시에는 엔진(30)의 효율이 P2 모터(12)의 효율에 비해 떨어지기 때문에 효율이 더 좋은 P2 모터(12)를 사용하여 차량의 초기 출발을 시작하는 것이 차량의 연비 측면에서 유리하다.In particular, since the efficiency of the engine 30 is lower than that of the P2 motor 12 at the initial start of the vehicle, starting the initial start of the vehicle using the P2 motor 12 with better efficiency is preferred in terms of fuel efficiency of the vehicle. advantageous in

일정 속도 이상의 차량 주행 시 등 특정 주행 조건에서 선택되는 HEV 모드는 엔진(30)과 P1 모터(11) 및 P2 모터(12)가 함께 구동하여 이들의 동력원으로부터 차량의 구동력을 얻는다.In the HEV mode selected under specific driving conditions, such as when driving a vehicle at a speed higher than a certain speed, the engine 30 and the P1 motor 11 and the P2 motor 12 are driven together to obtain a driving force of the vehicle from their power sources.

엔진 클러치(13)가 엔진(30)과 연결되어 있는 P1 모터(11)와 P2 모터(12) 사이의 동력을 연결하면 엔진(30)의 동력과 P1 모터(11) 및 P2 모터(12)의 동력이 함께 구동축을 거쳐 구동바퀴(W)에 전달된다.When the engine clutch 13 connects the power between the P1 motor 11 and the P2 motor 12 connected to the engine 30 , the power of the engine 30 and the power of the P1 motor 11 and the P2 motor 12 are Power is transmitted to the driving wheel W through the driving shaft together.

엔진(30)의 동력은 토션 댐퍼(20)를 거쳐 P1 모터(11)로 전달된다. 엔진(30)의 동력은 엔진(30)의 진동과 함께 토션 댐퍼(20)로 전달되는데 엔진(30)의 진동은 토션 댐퍼(20)에서 흡수된다.The power of the engine 30 is transmitted to the P1 motor 11 through the torsion damper 20 . The power of the engine 30 is transmitted to the torsion damper 20 together with the vibration of the engine 30 , and the vibration of the engine 30 is absorbed by the torsion damper 20 .

엔진(30)의 진동이 토션 댐퍼(20)에서 흡수됨에 따라 P1 모터(11) 및 변속기(14)은 엔진(30)의 진동에 직접적으로 영향을 받지 않는다. 이로 인해 P1 모터(11) 및 변속기(14)의 성능과 품질을 향상시킬 수 있다.As the vibration of the engine 30 is absorbed by the torsion damper 20 , the P1 motor 11 and the transmission 14 are not directly affected by the vibration of the engine 30 . Due to this, the performance and quality of the P1 motor 11 and the transmission 14 can be improved.

EV 주행모드 및 HEV 주행모드 선택은 엔진 클러치(13)의 작동을 제어함으로써 수행할 수 있다. EV 주행모드에서 HEV 주행모드로 전환할 때 엔진 클러치(13)의 동력 연결작동이 필요한데 이러한 엔진 클러치(13)의 동력 연결작동은 유압장치 등과 같은 장치에 의해 제어될 수 있다.Selection of the EV driving mode and the HEV driving mode may be performed by controlling the operation of the engine clutch 13 . When switching from the EV driving mode to the HEV driving mode, a power connection operation of the engine clutch 13 is required, and the power connection operation of the engine clutch 13 may be controlled by a device such as a hydraulic device.

In addition, the present invention can further improve the performance of the P1 motor due to the forced cooling of the P1 motor by the lubricating oil of the transmission device.
