일반적으로 토크 컨버터는, 차량의 엔진과 변속기 사이에 설치되어 유체를 이용하여 엔진의 구동력을 변속기에 전달하는 것이다. 이러한 토크 컨버터는, 엔진의 구동력을 전달받아 회전하는 임펠러, 이 임펠러에서 토출되는 오일에 의해 회전되는 터빈, 그리고 임펠러로 되돌아 흐르는 오일의 흐름을 임펠러의 회전 방향으로 향하게 하여 토크 변화율을 증대시키는 리엑터('스테이터' 라고도 함)를 포함한다.In general, the torque converter is installed between the engine of the vehicle and the transmission to transmit the driving force of the engine to the transmission using a fluid. Such a torque converter includes an impeller rotating under the driving force of the engine, a turbine rotated by the oil discharged from the impeller, and a reactor for increasing the rate of torque change by directing the flow of oil flowing back to the impeller in the direction of rotation of the impeller Quot; stator ").

토크 컨버터는 엔진에 작용하는 부하가 커지면 동력전달 효율이 저하될 수 있으므로 엔진과 변속기 사이를 직접 연결하는 수단인 록업 클러치(Lock up clutch, 또는 '댐퍼 클러치'라고도 함)를 갖추고 있다. 록업 클러치는 엔진과 직결된 프론트 커버와 터빈 사이에 배치되어 엔진의 회전 동력이 직접 터빈을 통하여 변속기로 전달될 수 있도록 한다.The torque converter is equipped with a lock-up clutch (also called a "damper clutch"), which is a means of directly connecting the engine to the transmission, as power transmission efficiency may be degraded if the load acting on the engine is increased. The lockup clutch is disposed between the front cover and the turbine directly connected to the engine so that the rotational power of the engine can be transmitted directly to the transmission through the turbine.

The driving force transmitted to the compression coil spring 17 is transmitted to the driven plate 19. The driving force of the engine transmitted to the driven plate 19 is transmitted to the spline hub 13 connected to the transmission.

본 발명의 실시예는 임펠러(3)와 터빈(5)에서 작용하는 유체에 의해 엔진의 구동력이 변속기로 동력전달이 이루어지는 경우에도 록업 및 댐핑 수단에 의해 원주 방향의 진동 및 충격을 흡수할 수 있다.The embodiment of the present invention can absorb the vibration and shock in the circumferential direction by the lockup and damping means even when the driving force of the engine is transmitted to the transmission by the fluid acting on the impeller 3 and the turbine 5. .

계속해서 록업 작동이 이루어져 엔진의 구동력이 스플라인 허브(13)를 통해 변속기로 직접 전달하는 과정을 설명한다.Next, the lockup operation is performed to describe a process in which the driving force of the engine is directly transmitted to the transmission through the spline hub 13.

프론트 커버(1)와 터빈 쉘(5a) 사이로 유압이 작용하면 터빈 쉘(5a)이 축 방향으로 이동하면서 제1 연장부(5a)에 결합된 마찰재(9)가 제2 연장부(3b)에 밀착되어 마찰 접촉한다.When hydraulic pressure acts between the front cover 1 and the turbine shell 5a, the friction material 9 coupled to the first extension portion 5a moves to the second extension portion 3b while the turbine shell 5a moves in the axial direction. It is in close contact and frictional contact.

이때 프론트 커버(1)로 전달된 구동력은 임펠러 쉘(3a)의 제2 연장부(3b)를 통해 임펠러 쉘(3a)에 전달된다. 임펠러 쉘(3a)에 전달된 엔진의 구동력은 마찰재(9)를 통해 터빈 쉘(5a)의 제1 연장부(5b)로 전달된다.At this time, the driving force transmitted to the front cover 1 is transmitted to the impeller shell 3a through the second extension part 3b of the impeller shell 3a. The driving force of the engine transmitted to the impeller shell 3a is transmitted to the first extension 5b of the turbine shell 5a through the friction material 9.

터빈 쉘(5a)의 제1 연장부(5b)로 전달된 엔진의 구동력은 리테이닝 플레이트(15)로 전달된다.The driving force of the engine transmitted to the first extension 5b of the turbine shell 5a is transmitted to the retaining plate 15.

리테이닝 플레이트(15)로 전달된 엔지의 구동력은 원주방향으로 압축 코일 스프링(17)을 압축하여 회전 방향의 진동 및 충격을 흡수한다. 압축 코일 스프링(17)으로 전달된 구동력은 드리븐 플레이트(19)로 전달된다. 드리븐 플레이트(19)로 전달된 엔진의 구동력은 변속기와 연결된 스플라인 허브(13)로 전달된다. The driving force of the engine transmitted to the retaining plate 15 compresses the compression coil spring 17 in the circumferential direction to absorb vibration and shock in the rotational direction. The driving force transmitted to the compression coil spring 17 is transmitted to the driven plate 19. The driving force of the engine transmitted to the driven plate 19 is transmitted to the spline hub 13 connected to the transmission.

이와 같이 본 발명의 실시예는 록업의 작동이 이루어지는 경우에도 록업 및 댐핑 수단에 의해 원주 방향의 진동 및 충격을 흡수할 수 있다.Thus, the embodiment of the present invention can absorb the vibration and shock in the circumferential direction by the lock-up and damping means even when the lock-up operation is performed.

본 발명의 실시예는 유체에 의한 동력전달 영역을 대폭 축소하고 록업 및 댐핑 수단을 임펠러 및 터빈 보다 외경쪽에 배치하여 크게 설계할 수 있어 유체에 의한 동력전달보다는 록업에 의한 동력전달을 극대화시킬 수 있다. The embodiment of the present invention can greatly reduce the power transmission area by the fluid and can be designed to be larger by placing the lockup and damping means on the outer diameter side than the impeller and the turbine to maximize the power transfer by the lockup rather than the power transfer by the fluid. .

또한, 본 발명의 실시예는 록업 및 댐핑 수단을 설치할 수 있는 충분한 공간을 확보하므로 록업 및 댐핑 수단 또는 토셔널 댐퍼의 설계 자유도를 증대시키고 전장의 길이를 축소시켜 하이브리드 차량에 장착할 때 장착성을 향상시킬 수 있다.In addition, the embodiment of the present invention secures sufficient space for installing the lockup and damping means, thereby increasing the design freedom of the lockup and damping means or the tonal damper and reducing the length of the electric field, thereby improving the mountability when mounted on the hybrid vehicle. You can.

이상을 통해 본 발명의 바람직한 실시예에 대하여 설명하였지만, 본 발명은 이에 한정되는 것이 아니고 특허청구범위와 발명의 상세한 설명 및 첨부한 도면의 범위 안에서 여러 가지로 변형하여 실시하는 것이 가능하고 이 또한 본 발명의 범위에 속하는 것은 당연하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
