An oil pump has a motor(9) positioned between an engine(1) and a planet gear set(5). The oil pump is provided inside a rotor(25) of the motor(9) and driven by an output shaft of the engine(1) to provide a hydraulic pressure to a continuously variable transmission(CVT). The output shaft of the engine(1) is connected to the oil pump(19) through a torsional damper, and the rotation shaft of the oil pump(19) is connected to the sun gear of the planet gear set(5). The hydraulic pressure of the oil pump(19) is provided to a driving-shaft variable pulley(13) and a driven-shaft variable pulley(15) of the CVT through a pipe(23).

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명 실시예는 엔진(1)의 출력축이 연결된 선기어(3)를 구비한 유성기어세트(5)와; 상기 유성기어세트(5)의 캐리어(7)에 연결된 모터(9)와; 상기 유성기어세트(5)의 링기어(11)에 구동축가변풀리(13)가 연결된 CVT와; 상기 CVT의 구동축가변풀리(13)와 종동축가변풀리(15) 및 상기 모터(9)를 제어하는 컨트롤러(17)를 포함하여 구성된다.1, an embodiment of the present invention includes a planetary gear set 5 having a sun gear 3 connected to an output shaft of an engine 1; A motor 9 connected to the carrier 7 of the planetary gear set 5; A CVT connected with a drive shaft variable pulley 13 to a ring gear 11 of the planetary gear set 5; And a controller 17 for controlling the drive shaft variable pulley 13, the driven shaft variable pulley 15, and the motor 9 of the CVT.

상기 엔진(1)과 상기 유성기어세트(5)의 사이에는 상기 모터(9)가 위치하고, 상기 모터(9)의 로터(25) 내측에는 엔진(1)의 출력축에 의해 구동되어 상기 CVT에 유압을 제공하는 오일펌프(19)가 구비되어 있다.The motor 9 is positioned between the engine 1 and the planetary gear set 5, and is driven by an output shaft of the engine 1 inside the rotor 25 of the motor 9 to supply hydraulic pressure to the CVT. An oil pump 19 is provided.

즉, 상기 엔진(1)의 출력축은 토셔널댐퍼(21)를 통하여 상기 오일펌프(19)로 연결되고, 상기 오일펌프(19)의 회전축은 상기 유성기어세트(5)의 선기어(3)에 연결된 구조이다.That is, the output shaft of the engine 1 is connected to the oil pump 19 through the torsional damper 21, and the rotation shaft of the oil pump 19 is connected to the sun gear 3 of the planetary gear set 5. It is a connected structure.

상기 오일펌프(19)에서 발생된 오일압은 상기 CVT의 구동축가변풀리(13) 및 상기 종동축가변풀리(15)의 작동압으로 사용되도록 관로(23)가 구비되며, 이는 상기 컨트롤러(17)에 의해 제어되도록 되어 있다.The oil pressure generated in the oil pump 19 is provided with a conduit 23 to be used as the operating pressure of the drive shaft variable pulley 13 and the driven shaft variable pulley 15 of the CVT, which is the controller 17 It is controlled by.

상기 오일펌프(19)가 상기 모터(9)의 로터(25) 내측으로 위치하고 별도의 클러치나 브레이크를 채용하지 않음으로써, 동력전달장치의 길이를 축소할 수 있게 된 구성이다.Since the oil pump 19 is located inside the rotor 25 of the motor 9 and does not employ a separate clutch or brake, the length of the power transmission device can be reduced.

상기 CVT의 종동축은 다수의 기어를 통하여 디퍼렌셜(27)로 회전력을 전달할 수 있게 되어 있고, 물론 상기 디퍼렌셜(27)을 통해서는 양쪽의 구동륜(29)으로 동력이 전달된다.The driven shaft of the CVT is capable of transmitting rotational force to the differential 27 through a plurality of gears, and of course power is transmitted to both drive wheels 29 through the differential 27.

상기 컨트롤러(17)는 상기 모터(9)의 속도를 제어하여 구동륜(29)의 전진과 후진 상태를 변화시키도록 된 것을 사용하는데, 그 제어는 상기 엔진(1)으로부터 입력되는 회전력으로 상기 선기어(3)가 회전되는 속도에 대하여 상기 캐리어(7)의 회전속도를 제어하여 상기 링기어(11)로 출력되는 회전력의 방향을 조절할 수 있도록 하는 것이다.The controller 17 is used to control the speed of the motor 9 to change the forward and backward states of the drive wheel 29, the control is the rotational force input from the engine (1) the sun gear ( By controlling the rotational speed of the carrier 7 with respect to the speed at which the 3) is rotated, the direction of the rotational force output to the ring gear 11 can be adjusted.

즉, 도 2를 참고할 때, 다음의 수학식 1을 만족하면 상기 링기어(11)의 회전방향은 양의 방향으로 상기 구동륜(29)은 전진방향으로 구동되고, 수학식 2를 만족하면 상기 링기어(11)의 회전방향은 음의 방향으로 상기 구동륜(29)은 후진방향으로 구동되는 것이다.That is, referring to FIG. 2, when the following Equation 1 is satisfied, the rotation direction of the ring gear 11 is driven in the positive direction, and the driving wheel 29 is driven in the forward direction. The rotation direction of the gear 11 is a negative direction, the driving wheel 29 is driven in the reverse direction.

Figure 112006058568035-pat00002
Figure 112006058568035-pat00002

여기서, VC는 캐리어(7) 회전속도, VS는 선기어(3) 회전속도, NS는 선기어(3) 잇수, NR은 링기어(11) 잇수이다.Here, V C is the rotational speed of the carrier 7, V S is the rotational speed of the sun gear 3, N S is the number of teeth of the sun gear (3), N R is the number of rings of the ring gear (11).

따라서, 별도의 클러치나 브레이크를 사용하지 않고 차량의 전진과 후진을 상기 모터(9)의 회전속도만을 제어하여 구현할 수 있게 되는 것이다.Therefore, it is possible to implement forward and backward of the vehicle by controlling only the rotational speed of the motor 9 without using a separate clutch or brake.

이상과 같이 본 발명에 의하면, 별도의 클러치나 브레이크를 사용하지 않고도 전진과 후진 등의 주행모드를 구현할 수 있도록 하여, 컴팩트한 동력전달장치의 구성이 가능하여 차량에의 탑재성이 크게 향상된다.As described above, according to the present invention, it is possible to implement a driving mode such as forward and reverse without using a separate clutch or brake, it is possible to configure a compact power transmission device, and the mountability on the vehicle is greatly improved.
