Field of the Invention [0001] The present invention relates to a power transmission apparatus for a hybrid vehicle, and more particularly, to a power transmission apparatus for a hybrid vehicle that can perform an engine start, a transmission, and a power transmission function using two motors and two friction members will be.
자동차의 친환경 기술은 미래 자동차 산업의 생존이 달린 핵심기술로서, 선진 자동차 메이커들은 환경 및 연비 규제를 달성하기 위한 친환경 자동차 개발에 총력을 기울이고 있다.The environmentally friendly technology of automobiles is a core technology with survival of the future automobile industry, and advanced automobile manufacturers are concentrating on development of environmentally friendly vehicles to achieve environmental and fuel efficiency regulations.
이에 따라 각 자동차 메이커들은 전기 자동차(EV : Electric Vehicle), 하이브리드 전기 자동차(HEV : Hybrid Electric Vehicle), 연료전지 자동차(FCEV : Fuel Cell Electric Vehicle)등을 미래형 자동차 기술로서 개발하고 있다.Accordingly, automobile manufacturers are developing electric vehicles (EVs), hybrid electric vehicles (HEVs), and fuel cell electric vehicles (FCEVs) as futuristic automobile technologies.
상기와 같은 미래형 자동차는 중량 및 원가 등 여러 가지 기술적인 제약이 있기 때문에 자동차 메이커에서는 배기가스 규제를 만족시키고, 연비 성능의 향상을 위한 현실적인 문제의 대안으로서 하이브리드 자동차에 주목하고 있으며, 이를 실용화하기 위해 치열한 경쟁을 벌이고 있다. Because the above-mentioned future type of automobile has various technical limitations such as weight and cost, automakers pay attention to the hybrid vehicle as an alternative to realistic problems for satisfying exhaust gas regulations and improving fuel efficiency, and in order to put them into practical use There is intense competition.

도 2는 본 발명의 실시 예에 따른 동력전달장치에 적용되는 마찰부재의 각 주행 모드별 작동표이고, 제3 내지 도 6은 각 주행 모드별 동력 전달 경로도이다.FIG. 2 is an operation table for each traveling mode of the friction member applied to the power transmitting apparatus according to the embodiment of the present invention, and FIGS. 3 to 6 are power transmission path diagrams for each traveling mode.
차량의 출발 또는 저속과 정속 구간에서 모터로만 차량을 운행하는 EV 주행모드에서는 도 1 및 도 2에서와 같이, 마찰부재(BK)(CL)는 전혀 작동하지 않는다.In the EV running mode in which the vehicle is driven only by the motor at the start of the vehicle or at the low speed and the constant speed, the friction member BK (CL) does not operate at all, as shown in Figs.
따라서 배터리(B)의 전원을 에너지원으로 한 제2 모터/제너레이터(MG2)의 구동력이 종감속기어 세트(FD)를 통해 구동륜(W)로 전달되어 EV 주행모드로서 주행한다.The driving force of the second motor / generator MG2 using the power source of the battery B as the energy source is transmitted to the drive wheel W via the longitudinally driven reduction gear set FD and travels as the EV drive mode.
상기와 같은 EV 주행모드 과정에서 엔진(ENG)을 시동하고자 할 때에는 EV 주행모드에서 도 2에서와 같이 브레이크(BK)를 작동시키면 도 3에서와 같은 동력 전달경로로 동력 전달이 이루어지면서 주행한다.When the engine ENG is to be started in the EV traveling mode process as described above, when the brake BK is operated in the EV traveling mode as shown in FIG. 2, the vehicle travels through the power transmission path as shown in FIG.
상기와 같이 엔진(ENG)을 시동시킨 후에는 도 4에서와 같이 엔진(ENG)의 회전 동력이 전기적인 경로를 통해 제2 모터/제너레이터(MG2)를 구동시키는 직렬형 동력전달경로로 이루어진다.After starting the engine (ENG) as described above, the engine (ENG) has a series power transmission path in which the rotational power of the engine (ENG) drives the second motor / generator (MG2) through an electric path.
그리고 브레이크(BK)의 작동이 해제된 상태에서 제1 스테이터(ST1)와 제2 로터(RT2)의 회전 속도가 유사해지면 되고, 클러치(CL)를 작동 제어하여 엔진(ENG)의 회전 동력이 제1 스테이터(ST1)와 제2 로터(RT2)를 통해 종감속기어 세트(FD)로 공급되어 주행이 이루어지며, 이러한 주행 과정에서 배터리 충전시에는 도 5와 같은 동력전달경로로 동력 전달이 이루어지며, 배터리 방전시에는 도 6과 같은 동력전달 경로로 동력 전달이 이루어진다. When the operation of the brake BK is released, the rotational speeds of the first and second rotors ST1 and RT2 become similar to each other, and the clutch CL is operated to control the rotational force of the engine ENG The power is transmitted to the longitudinal reduction gear set FD through the first stator ST1 and the second rotor RT2 and traveled through the power transmission path as shown in FIG. , And when the battery is discharged, the power is transmitted through the power transmission path as shown in Fig.
상기에서와 같이 본 발명의 실시예에 따른 동력전달장치는 브레이크(BK)를 체결한 상태에서 제2 모터/제너레이터(MG2)를 이용하여 EV 주행모드의 운전이 가능하고, 이 상태에서 엔진(ENG)의 시동할 경우에는 배터리(B)에 저장된 에너지를 활용하여 제1 모터/제너레이터(MG1)의 제1 로터(RT1)를 구동시키면 된다.As described above, the power transmission apparatus according to the embodiment of the present invention can operate in the EV traveling mode using the second motor / generator MG2 while the brake BK is engaged. In this state, the engine ENG , The energy stored in the battery B may be used to drive the first rotor RT1 of the first motor / generator MG1.
또한, 엔진(ENG)의 시동 후에는 엔진(ENG)의 회전동력이 전기적인 경로를 통해 제2 모터/제너레이터(MG2)를 구동시키게 되며, 이후 브레이크(BK)의 작동을 해제하고 제1 스테이터(ST1)와 제2 로터(RT2)의 회전속도가 거의 동일할 때에 클러치(CL)를 체결하여 엔진 동력이 제1 스테이터(ST1)와 제2 로터(RT2)를 통해 종감속기어 세트(FD)로 전달되면서 차량을 구동시킬 수 있다.After the start of the engine ENG, the rotational power of the engine ENG drives the second motor / generator MG2 through the electric path. Thereafter, the operation of the brake BK is released and the first stator ST1 and the second rotor RT2 are substantially equal to each other and the clutch CL is engaged so that engine power is transmitted to the longitudinal reduction gear set FD via the first stator ST1 and the second rotor RT2 The vehicle can be driven while being transmitted.
