A motor is installed between the engine and the torque converter, and a separate clutch is provided between the engine and the motor to control power transmission.

For torque converters, always turn the power train.

종래에는 파워트레인을 장착한 하이브리드 자동차에서 토크 컨버터가 설치된 경우, 토크 컨버터의 락업 클러치와 엔진과 모터의 사이에 설치된 클러치의 기능이 중복되므로 탑재성이 저하되며 생산원가와 제품중량은 상승하는 문제점이 있다. 따라서 이를 개선할 필요성이 요청된다.Conventionally, when a torque converter is installed in a hybrid vehicle equipped with a power train, since the functions of the lock-up clutch of the torque converter and the clutch installed between the engine and the motor are overlapped, the mounting property is lowered and the production cost and product weight are increased have. Therefore, there is a need for improvement.

The motor unit 30 shown in Fig.

토크컨버터(40)는 원동축(原動軸)과 부하(負荷)를 유체를 매개로 결합하여 동력을 전달하고, 부하의 변동에 따라 자동으로 변속작용을 하는 유체변속장치이다. 일 실시예에 따른 토크컨버터(40)는 프론트 커버(41)와 임펠러(42)와 터빈(43)과 댐퍼부(45)와 동력제어부(46)와 리엑터(47)와 락업 클러치(50)를 포함한다.The torque converter 40 is a fluid transmission device that transmits a power by coupling a driving shaft and a load (load) via a fluid and automatically performs a shifting action according to a variation of the load. The torque converter 40 according to the embodiment includes the front cover 41, the impeller 42, the turbine 43, the damper portion 45, the power control portion 46, the reactor 47, and the lockup clutch 50 .

이러한 토크컨버터(40)는, 엔진부(10)의 크랭크축에 연결되어 회전하는 프론트 커버(41), 프론트 커버(41)에 연결되어 함께 회전하는 임펠러(42), 임펠러(42)와 마주하는 위치에 배치되는 터빈(43), 임펠러(42)와 터빈(43)의 사이에 위치하며 터빈(43)으로부터 나오는 오일의 흐름을 바꾸어 임펠러(42) 측으로 전달하는 리엑터(47) 및 엔진부(10)와 파워트레인(20)을 직접 연결하는 락업 클러치(50)를 포함한다.The torque converter 40 includes a front cover 41 connected to the crankshaft of the engine unit 10 and rotating, a impeller 42 connected to the front cover 41 and rotating together, A reactor 47 disposed between the impeller 42 and the turbine 43 for changing the flow of oil from the turbine 43 and transferring the flow of oil to the impeller 42 side, Up clutch 50 that directly connects the power train 20 and the power train 20.

임펠러(42)의 측으로 오일을 전달하는 리엑터(47)는 프론트 커버(41)와 동일한 회전 중심을 가진다. 그리고 락업 클러치(50)는 프론트 커버(41)와 터빈(43)의 사이에 배치된다. 락업 클러치(50)는 원판 형상으로 형성되며 축 방향으로 이동할 수 있는 피스톤(52)을 구비한다.The reactor 47 for transmitting the oil to the impeller 42 has the same center of rotation as the front cover 41. The lockup clutch 50 is disposed between the front cover 41 and the turbine 43. The lock-up clutch 50 is formed in a disk shape and has a piston 52 which is movable in the axial direction.

그리고 락업 클러치(50)에는 댐퍼부(45)가 결합된다. 댐퍼부(45)는 락업 클러치(50)를 통해 전달되는 구동력을 터빈(43)에 전달하여 축의 회전 방향으로 작용하는 비틀림력을 흡수하고 진동을 감쇄시키는 역할을 한다.And the damper portion 45 is engaged with the lockup clutch 50. The damper unit 45 transmits the driving force transmitted through the lockup clutch 50 to the turbine 43 to absorb the twisting force acting in the rotating direction of the shaft and attenuate the vibration.

또한 락업 클러치(50)는 프론트 커버(41)와 피스톤(52)의 사이에 배치되는 마찰 플레이트(54)를 포함하며, 마찰 플레이트(54)의 양측면에는 마찰재(56)가 결합된다. 따라서 유압에 의해 피스톤(52)이 프론트 커버(41)를 향하는 방향으로 이동하면, 마찰재(56)들이 프론트 커버(41)와 피스톤(52)에 밀착되면서 프론트 커버(41)로 전달된 구동력이 마찰 플레이트(54)로 전달될 수 있다.The lockup clutch 50 also includes a friction plate 54 disposed between the front cover 41 and the piston 52. The friction plate 56 is coupled to both sides of the friction plate 54. [ Therefore, when the piston 52 moves in the direction toward the front cover 41 by the hydraulic pressure, the friction materials 56 are brought into close contact with the front cover 41 and the piston 52, Plate 54 as shown in FIG.

락업 클러치(50)는 프론트 커버(41)와 터빈(43)의 사이에 배치되며 동력전달을 허용하거나 차단한다. 그리고 댐퍼부(45)는 락업 클러치(50)에 결합되어 진동을 감쇄시키는 기능을 구현한다.Up clutch 50 is disposed between the front cover 41 and the turbine 43 and allows or blocks power transmission. The damper portion 45 is coupled to the lock-up clutch 50 to implement the function of attenuating vibration.

동력제어부(46)는 터빈(43)과 모터부(30)의 사이에 설치되며, 터빈(43)에서 모터부(30)를 향한 방향으로 동력이 전달됨은 허용하며, 모터부(30)에서 터빈(43)을 향한 방향으로 동력이 전달됨은 차단한다. 일 실시예에 따른 동력제어부(46)는 원웨이 클러치를 사용한다.The power control unit 46 is installed between the turbine 43 and the motor unit 30 and allows the power to be transmitted from the turbine 43 toward the motor unit 30, (43). ≪ / RTI > The power control unit 46 according to one embodiment uses a one-way clutch.

원웨이 클러치를 사용하는 동력제어부(46)는 하이브리드 자동차(1)의 회생제동시 효율 극대화를 위해 차량 휠부재(60)의 회전이 토크컨버터(40)의 임펠러(42)와 터빈(43)으로 전달됨을 차단한다. 회생제동은 전동기의 제동방법의 하나로, 전동기를 발전기로 동작시킨 후 발생된 전력을 전원으로 되돌리는 제동방법이다.The power control unit 46 using the one-way clutch controls the rotation of the vehicle wheel member 60 to the impeller 42 and the turbine 43 of the torque converter 40 in order to maximize efficiency in regenerative braking of the hybrid vehicle 1 And blocks transmission. Regenerative braking is one of the braking methods of electric motors. It is a braking method that returns the generated electric power to the power source after operating the motor as a generator.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 하이브리드 자동차(1)의 작동상태를 상세히 설명한다.Hereinafter, an operation state of the hybrid vehicle 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

엔진부(10)에서 휠부재(60)를 향하여 부품들이 배치될 때, 엔진부(10)와 토크컨버터(40)와 모터부(30)와 파워트레인(20)의 순서로 배치된다. 그리고 엔진부(10)의 동력만 토크컨버터(40)와 파워트레인(20)을 통하여 휠부재(60)로 전달될 수 있다. 또는 엔진부(10)의 동력과 모터부(30)의 동력이 동시에 파워트레인(20)으로 전달된 후 휠부재(60)를 통해 출력될 수 있다.The torque converter 40, the motor unit 30 and the power train 20 are arranged in this order when the components are arranged in the engine unit 10 toward the wheel member 60. [ Only the power of the engine unit 10 can be transmitted to the wheel member 60 through the torque converter 40 and the power train 20. Or the power of the engine unit 10 and the power of the motor unit 30 may be simultaneously transmitted to the power train 20 and then output through the wheel member 60. [

그리고, 엔진부(10)의 동력 없이 모터부(30)의 동력만 파워트레인(20)으로 입력된 후 휠부재(60)를 통해 출력될 수 있다.Only the power of the motor unit 30 can be input to the power train 20 and output through the wheel member 60 without the power of the engine unit 10. [

엔진부(10)와 모터부(30)의 사이에는 별도의 클러치가 설치되어야 하며, 토크컨버터(40)의 락업 클러치(50)를 공용으로 사용하므로 탑재성이 향상되며, 생산원가는 절감되고, 부품의 중량과 부품수와 제어요소가 감소될 수 있다.A separate clutch must be provided between the engine unit 10 and the motor unit 30. Since the lockup clutch 50 of the torque converter 40 is commonly used, the mountability is improved, the production cost is reduced, The weight of the part, the number of parts and the control element can be reduced.

한편, 터빈(43)과 모터부(30)의 사이에는 원웨이 클러치를 사용하는 동력제어부(46)가 설치되므로, 회생제동시 모터부(30)를 발전시키는 동력이 터빈(43)으로 전달됨을 차단한다. 동력제어부(46)는 터빈(43)에서 모터부(30)로 이동되는 동력은 허용하며, 모터부(30)에서 터빈(43)으로 이동되는 동력은 차단한다.Since a power control unit 46 using a one-way clutch is provided between the turbine 43 and the motor unit 30, the power for generating the motor unit 30 during regenerative braking is transmitted to the turbine 43 . The power control unit 46 allows power to be transferred from the turbine 43 to the motor unit 30 and blocks power from the motor unit 30 to the turbine 43.

따라서 회생제동시 휠부재(60)를 통해 입력된 동력이 모터부(30)로 전달되어 발전이 이루어질 때, 모터부(30)에서 터빈(43)으로 이동되는 동력이 차단되므로 발전효율을 향상시킬 수 있다.Therefore, when the power inputted through the wheel member 60 is transmitted to the motor unit 30 and power generation is performed during the regenerative braking, the power for moving from the motor unit 30 to the turbine 43 is cut off, .

상술한 바와 같이, 본 발명에 따르면 엔진부(10)와 모터부(30)의 사이에 설치되는 클러치의 개수가 감소되어 생산원가를 절감하며 탑재성이 향상될 수 있다.As described above, according to the present invention, the number of clutches provided between the engine unit 10 and the motor unit 30 is reduced, so that the production cost can be reduced and the mountability can be improved.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.
