Description

하이브리드 차량용 파워트레인{POWERTRAIN FOR HYBRID VEHICLE}[0001] POWERTRAIN FOR HYBRID VEHICLE [0002]

본 발명은 하이브리드 차량에 적용되는 파워트레인에 관한 것이다.
The present invention relates to a power train applied to a hybrid vehicle.

하이브리드 자동차는 전기의 동력과 내연기관의 동력원을 조합하여 구동하는 자동차로서, 엔진과 전기 모터로 시스템의 효율이 높은 지점에서 동작되도록 제어하여 효율이 우수하면서 배기가스를 효과적으로 줄일 수 있는바, 친환경 자동차의 대안으로 실용화되고 있는 실정에 있다.
A hybrid vehicle is an automobile that combines the power of an electric power and the power source of an internal combustion engine. The hybrid vehicle is controlled by an engine and an electric motor to operate at a high efficiency point to effectively reduce exhaust gas, Which is now being put to practical use as an alternative.

이러한, 하이브리드 자동차의 동력분기방식은 유성기어와 같이 동력 흐름을 분기하는 동력분기장치를 사용하여 엔진의 동력을 직접 출력축으로 전달하는 기계적 흐름과 엔진의 동력을 이용하여 제너레이터를 발전하고, 이 발전된 동력을 이용하여 배터리를 충전하거나 충전된 배터리의 에너지로 모터를 구동하는 전기적 흐름으로 구성된다.Such a hybrid vehicle power branching system uses a mechanical flow for directly transmitting the power of the engine to the output shaft by using a power branching device for branching the power flow like a planetary gear and the power of the engine to develop the generator, And an electric current that drives the motor by the energy of the charged battery.

상기와 같은 동력분기방식 하이브리드 시스템은 엔진이 출력축과 독립적으로 작동이 가능하고 주행 중 엔진을 자유롭게 온/오프할 수 있으며 전기차 모드 구현이 가능한 장점이 있다.The power split hybrid system as described above has an advantage that the engine can operate independently of the output shaft and can freely turn the engine on and off while driving and can realize the electric vehicle mode.

또한, 2개의 모터제너레이터에 의한 전기적 무단 변속기(Electrically Variable Transmission: EVT) 효과로 엔진을 효율적으로 운전시킬 수 있는 장점을 가지고 있고, 모터는 속도에 따라 출력이 일정하므로, 기본적으로 변속기가 불필요하다. In addition, it has an advantage that an engine can be efficiently operated by an electrically variable transmission (EVT) effect by two motor generators, and since a motor has a constant output according to a speed, a transmission is basically unnecessary.

하지만, 차량의 최고 속도가 높으면서 저속 토크를 확보하기 위해서는 변속기가 필요하게 된다.
However, a transmission is required in order to secure a low-speed torque while the maximum vehicle speed is high.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

예컨대, 상기 원웨이클러치(13)는 복수의 기어짝(G1,G2) 중 상대적으로 기어비가 큰 1단 기어짝(G1)의 출력기어(G1o)와 출력축(11) 사이에 구비될 수 있다. 이때에, 상기 1단 기어짝(G1)의 입력기어(G1i)는 전동입력축(5)에 상대 회전이 구속된 상태로 구비되어 전동입력축(5)과 함께 회전될 수 있으며, 이에 1단 기어짝(G1)을 이용한 EV모드 1단 주행시에 단속장치(9)가 1단 입력기어(G1i)에 결합되지 않고도, 제1전동기(MG1)의 동력이 1단 기어짝(G1)에 제공되는바, EV모드 1단 주행이 가능하게 된다.
For example, the one-way clutch 13 may be provided between the output gear G1o and the output shaft 11 of the first gear pair G1 having a relatively large gear ratio among the plurality of gear pairs G1 and G2. At this time, the input gear G1i of the first gear pair G1 is provided in a state where relative rotation is restricted to the electric input shaft 5 and can be rotated together with the electric input shaft 5, The power of the first electric motor MG1 is provided to the first gear pair G1 without engaging the interrupter 9 to the first stage input gear G1i at the time of the first mode of the EV mode using the electric motor G1, EV mode 1-stage running is possible.

아울러, 본 발명에서 제1마찰부재(C1)는 상기 기어짝(G1,G2) 중 상대적으로 기어비가 작은 기어짝과 전동입력축(5) 사이에 결합 및 분리 가능하게 마련될 수 있다.In addition, in the present invention, the first friction member C1 may be provided so as to be capable of being coupled and disconnected between the gear pair G1 and G2 and a gear pair having a relatively small gear ratio and between the electric input shaft 5 and the gear pair.

예컨대, 상기 제1마찰부재(C1)는 복수의 기어짝(G1,G2) 중 상대적으로 기어비가 작은 2단 기어짝(G2)의 입력기어(G2i)와 전동입력축(5) 사이에 구비될 수 있다. 여기서, 상기 제1마찰부재(C1)는 건식클러치가 사용될 수 있다.For example, the first friction member C1 may be provided between the input gear G2i of the second gear pair G2 having a relatively small gear ratio among the plurality of gear pairs G1 and G2 and the electric input shaft 5 have. Here, the first friction member (C1) may be a dry clutch.

즉, 변속기어장치(7)에 설치된 단속장치(9) 및 제1마찰부재(C1) 모두가 유압을 사용하지 않는 클러치가 사용됨으로써, 변속기의 중량 및 원가를 저감하게 되는 것이다.
That is, by using a clutch in which neither the interrupting device 9 provided in the transmission mechanism device 7 nor the first friction member C1 uses the hydraulic pressure, the weight and the cost of the transmission are reduced.

이 같은 구성에 따라, 본 발명은 원웨이클러치(13)의 작용과, 단속장치(9) 및 제1마찰부재(C1)의 선택적인 결합작동에 의해 EV모드 1단 및 2단 주행이 가능함으로써, 모터 구동에 따른 변속단을 다단화 형성하여 EV주행 성능을 향상시키고, 이에 따라 모터 용량을 축소하여 원가 및 중량을 저감하는 것이다.

한편, 본 발명은, 엔진(1) 또는 제2전동기(MG2)의 동력을 출력축(11)으로 분기하여 제공 가능한 유성기어장치(PG)를 더 포함하여 구성될 수 있다.
The present invention may further comprise a planetary gear set PG capable of branching the power of the engine 1 or the second electric motor MG2 to the output shaft 11. [

도 1을 참조하여 구체적으로 살펴보면, 유성기어장치(PG)는, 제2전동기(MG2)에 연결되어 선택적인 입력요소 또는 선택적인 고정요소로 작동되는 제1회전요소와, 엔진(1) 동력이 제공되어 선택적인 입력요소로 작동되는 제2회전요소와, 출력축(11)에 연결되어 선택적인 출력요소로 작동되는 제3회전요소를 포함하여 구성될 수 있다.1, the planetary gear set PG includes a first rotary element connected to the second electric motor MG2 and operated by an optional input element or an optional fixed element, A second rotary element provided with an optional input element, and a third rotary element connected to the output shaft 11 and operated as an optional output element.

예컨대, 상기 유성기어장치(PG)에서, 제1회전요소는 선기어(S)이고, 제2회전요소는 캐리어(CR)이며, 제3회전요소는 링기어(R)일 수 있다.
For example, in the above-mentioned planetary gear set PG, the first rotary element may be a sun gear S, the second rotary element may be a carrier CR, and the third rotary element may be a ring gear R.

그리고, 상기 유성기어장치(PG)의 제1회전요소에는 제2마찰부재(C2)가 연결되어, 상기 제1회전요소가 선택적인 고정요소로 작동되도록 구성할 수 있다.A second friction member (C2) is connected to the first rotary element of the planetary gear set (PG), so that the first rotary element is operated as an optional fixed element.

이때에, 상기 제2마찰부재(C2)는 도 1과 같이 변속기케이스(15)와 제1회전요소 사이에서 선택적으로 체결 가능한 도그클러치 또는 동기치합식의 싱크로장치일 수 있고, 또한 도 6과 같이 변속기케이스(15)에 고정되는 브레이크일 수도 있다.1, the second friction member C2 may be a dog clutch or a synchromesh type synchronous device that can be selectively engaged between the transmission case 15 and the first rotary element, And may be a brake fixed to the transmission case 15.

예컨대, 마찰부재(B)로서 도그클러치를 사용하는 경우에는, 제2전동기(MG2)의 회전수를 제어(회전수를 "0"으로 제어)함으로써, 도그클러치를 안정적으로 체결할 수 있다.For example, when the dog clutch is used as the friction member B, the dog clutch can be stably locked by controlling the rotational speed of the second electric motor MG2 (the rotational speed is controlled to be "0").

그리고, 도 7과 같이 제2마찰부재(C2)가 사용되지 않는 경우, 엔진EVT모드에서 고속 주행시에는, 비록 전기부하의 손실이 있기는 하지만 제2전동기(MG2)를 제어하여 유성기어장치(PG)의 선기어(S)를 고정시켜 주행할 수도 있을 것이다.When the second friction member C2 is not used as shown in Fig. 7, the second electric motor MG2 is controlled to drive the planetary gear set PG ) Of the sun gear S may be fixed.

여기서, 상기 제1전동기(MG1)와, 제2전동기(MG2)는 동력을 제공하거나 발전 가능한 모터제너레이터일 수 있다.
Here, the first electric motor MG1 and the second electric motor MG2 may be motor generators capable of providing or generating power.

즉, 선기어(S)는 제2마찰부재(C2)와 연결되어 제동이 가능하고, 캐리어(CR)는 엔진(1)과 연결되어 엔진(1)으로부터 회전동력을 선택적으로 제공받으며, 링기어(R)는 출력축(11)과 연결되어 상기 출력축(11)에 회전동력을 전달하는 역할을 한다.That is, the sun gear S is connected to the second friction member C2 to be braked, the carrier CR is connected to the engine 1 to selectively receive rotational power from the engine 1, R is connected to the output shaft 11 and transmits rotation power to the output shaft 11. [

이때에, 상기 엔진(1)과 캐리어(CR) 사이에는 토션댐퍼(3)가 마련되어 비틀림진동을 감소시킬 수 있다.
At this time, a torsional damper 3 is provided between the engine 1 and the carrier CR to reduce the torsional vibration.

따라서, 본 발명은 제2마찰부재(C2)의 선택적인 제동작동에 의해 엔진EVT(전기적 무단 변속기)모드, 또는 엔진OD(오버드라이브)모드의 주행이 가능하고, 더불어 EV모드 1단 및 2단 복합 주행을 통해 HEV모드를 구현함으로써, 변속단을 다단화 형성하여 차량의 고속 주행 성능을 향상시키게 되는 것이다.
Therefore, the present invention is capable of running in the engine EVT (electronic stepless transmission) mode or the engine OD (overdrive) mode by the selective braking operation of the second friction member C2, By implementing the HEV mode through hybrid driving, the speed change stage is formed in multiple shoes to improve the high-speed driving performance of the vehicle.

이하에서는, 본 발명을 이용한 주행모드별 동력 흐름을 살펴보기로 한다.Hereinafter, the power flow for each traveling mode using the present invention will be described.

<EV모드><EV mode>

도 2를 참조하면, 제1전동기(MG1)에서 제공되는 동력에 의해 전동입력축(5)이 회전하게 되는데, 이때에 제1전동기(MG1)에 제공된 동력이 1단 입력기어(G1i)를 거쳐 1단 출력기어(G1o)로 전달되면서 원웨이클러치(13)의 아우터레이스가 이너레이스를 끄는 방향으로 작동하게 된다.2, the electric power input shaft 5 is rotated by the power provided by the first electric motor MG1. At this time, the power supplied to the first electric motor MG1 is transmitted to the first electric motor MG1 via the first input gear G1i, The outer race of the one-way clutch 13 is operated in the direction to cut the inner race while being transmitted to the step output gear G1o.

즉, 제1전동기(MG1)의 회전 동력이 1단 기어짝(G1)과 원웨이클러치(13)를 통해 출력축(11)으로 출력됨으로써, EV모드 1단 변속단을 형성하여 주행하게 되는 것이다.
That is, the rotational power of the first electric motor MG1 is output to the output shaft 11 through the first gear pair G1 and the one-way clutch 13, thereby forming the EV mode 1-speed range stage and running.

이어서, 도 3을 참조하면, 제1전동기(MG1)에서 제공되는 동력에 의해 전동입력축(5)이 회전하게 되는데, EV모드 1단에서 EV모드 2단으로 변속시 먼저 제1마찰부재(C1)를 결합한 후, 제1전동기(MG1)를 이용하여 제1전동기(MG1)의 회전속도와 2단 입력기어(G2i)의 회전속도를 동기화한다.3, the transmission input shaft 5 is rotated by the power provided by the first electric motor MG1. When the first input shaft is shifted from the first EV mode to the second EV mode, The rotational speed of the first electric motor MG1 is synchronized with the rotational speed of the second input gear G2i by using the first electric motor MG1.

이 후, 단속장치(9)를 2단 입력기어(G2i)에 치합 결합하고, 이어서 제1마찰부재(C1)를 분리하게 됨으로써, 2단 기어짝(G2)을 통해 출력축(11)으로 출력이 이루어지게 되고, 이에 EV모드 2단의 변속단을 형성하여 주행하게 되는 것이다.Thereafter, the interrupter 9 is engaged with the two-stage input gear G2i, and then the first friction member C1 is disengaged, whereby the output to the output shaft 11 through the two-stage gear pair G2 So that the EV mode 2-speed stage is formed and driven.

이 경우, 1단 및 2단 기어비의 차이에 의해 외접기어(9)의 2단 출력기어(G2o)의 회전속도가 1단 출력기어(G1o)의 회전속도보다 빠르므로, 원웨이클러치(13)는 작동하지 않고 헛돌게 된다.In this case, the rotation speed of the two-stage output gear G2o of the external gear 9 is faster than the rotation speed of the first-stage output gear G1o due to the difference between the first-stage and second- Is idle and idle.

더불어, 상기한 변속과정에서 유압 또는 전기를 사용하여 작동하는 제1마찰부재(C1)는 변속시에만 사용을 하고, 변속 후에는 단속장치(9)로 변속단을 형성함으로써, 주행 중 유압 또는 전기 손실을 방지하여, 연비 향상에 도움을 주는 것이다.
In addition, the first friction member C1, which operates using hydraulic or electric power in the above-described shifting process, is used only at the time of shifting, and after shifting, the speed limiter is formed by the interrupter 9, To prevent loss, and to help improve fuel economy.
