Description

차량의 하이브리드 파워트레인{HYBRID POWER TRAIN FOR VEHICLE}[0001] HYBRID POWER TRAIN FOR VEHICLE [0002]

본 발명은 차량의 하이브리드 파워트레인에 관한 것으로서, 보다 상세하게는 내연기관인 엔진과, 전기로 구동되는 모터에서 출력되는 동력으로 차량의 구동력을 제공할 수 있도록 하는 차량의 파워트레인에 관련된 기술이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hybrid power train of a vehicle, and more particularly, to a hybrid power train of a vehicle, and more particularly to an engine as an internal combustion engine and a power train of a vehicle capable of providing a driving force of the vehicle with power output from an electrically driven motor.

내연기관인 엔진으로부터 발생되는 동력과 전기로 구동되는 모터에서 발생되는 동력을 적절히 조화롭게 운용하여 차량을 구동할 수 있도록 하는 하이브리드 파워트레인은, 기본적으로 엔진이 가지고 있는 토크 특성과 모터가 가지고 있는 토크 특성의 상호 보완적인 측면을 활용하여 차량 운행의 효율성을 향상시키도록 한다.
The hybrid power train, which is able to drive the vehicle by appropriately harmonizing the power generated by the engine, which is an internal combustion engine, and the power generated by the electric motor, is basically a combination of the torque characteristics of the engine and the torque characteristics Use complementary aspects to improve the efficiency of vehicle operation.

따라서, 종래의 하이브리드 파워트레인은 차량의 출발시나 저속의 상황에서 주로 모터에 의해 차량이 구동되도록 함으로써, 저속 토크특성이 우수한 모터의 특성을 활용하는 EV모드를 구현하고, 중속이나 고속의 상황에서는 상대적으로 토크 특성이 우수한 엔진으로 차량을 구동할 수 있도록 하며, 높은 토크가 요구되는 운전 상황에서는 엔진과 모터의 토크를 모두 사용할 수 있는 하이브리드 모드를 구현할 수 있도록 한다.
Therefore, the conventional hybrid power train realizes an EV mode that utilizes the characteristics of a motor having excellent low-speed torque characteristics by allowing the vehicle to be driven mainly by a motor at the start of a vehicle or at a low speed, Which can drive the vehicle with an engine having excellent torque characteristics and can realize a hybrid mode in which both the torque of the engine and the torque of the motor can be used in a driving state requiring high torque.

그런데, 종래의 하이브리드 파워트레인은 엔진에 의해 차량이 구동되는 상황에서 모터의 로터가 엔진으로부터의 동력에 의해 회전되는 구조를 가지고 있어서, 엔진만으로 차량이 구동되는 상황에서 상기와 같은 모터의 회전은 드래그 토크로 작용하고, 이는 곧 차량의 연비 악화의 원인이 된다.
However, the conventional hybrid power train has a structure in which the rotor of the motor is rotated by the power from the engine in a state where the vehicle is driven by the engine, so that in the situation where the vehicle is driven only by the engine, Torque, which causes deterioration of fuel efficiency of the vehicle.

또한, 반대로 모터만으로 차량이 구동되는 EV모드 상황에서는 가급적 엔진의 동력을 구동륜으로 전달하는 데에만 사용되는 구성 부품들로는 동력 전달이 차단되도록 하는 것이 모터에 의해 발생된 동력을 다른 손실 없이 보다 효율적으로 구동륜으로 전달할 수 있어서, 연비를 향상시킬 수 있다.
On the contrary, in the EV mode in which the vehicle is driven only by the motor, it is possible to prevent the power transmission from being blocked by the components used only to transmit the power of the engine to the drive wheels as much as possible, So that the fuel consumption can be improved.

상기의 발명의 배경이 되는 기술로서 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 will be appreciated that those skilled in the art will appreciate that the described embodiments are provided merely for the purpose of promoting an understanding of the background of the present invention, It will not.

도 1을 참조하면, 본 발명 차량의 하이브리드 파워트레인의 실시예는, 엔진의 동력을 선택적으로 공급받을 수 있도록 설치된 입력축(IN)과; 상기 입력축(IN)에 구비된 엔진측구동기어(1)와; 상기 입력축(IN)과 평행하게 배치된 출력축(OUT)과; 상기 엔진측구동기어(1)와 치합되도록 상기 출력축(OUT)에 회전 가능하게 구비된 엔진측피동기어(3)와; 상기 입력축(IN)과 동심축을 이루며 모터에 의해 회전되도록 설치된 모터측구동기어(5)와; 상기 모터측구동기어(5)와 치합되도록 상기 출력축(OUT)에 회전 가능하게 구비된 모터측피동기어(7)와; 상기 엔진측피동기어와 모터측피동기어(7)를 각각 상기 출력축(OUT)에 고정시키는 상태를 전환할 수 있도록 설치된 클러치수단(CL)을 포함하여 구성된다.
1, an embodiment of a hybrid power train according to the present invention includes an input shaft IN installed to selectively receive power from an engine; An engine side drive gear (1) provided on the input shaft (IN); An output shaft (OUT) arranged parallel to the input shaft (IN); An engine side driven gear (3) rotatably provided on the output shaft (OUT) so as to be engaged with the engine side drive gear (1); A motor-side drive gear (5) formed concentrically with the input shaft (IN) and configured to be rotated by a motor; A motor side driven gear (7) rotatably provided on the output shaft (OUT) to be engaged with the motor side drive gear (5); And a clutch means (CL) provided so as to switch a state of fixing the engine-side driven gear and the motor-side driven gear (7) to the output shaft (OUT), respectively.

상기 모터측피동기어(7)와 출력축(OUT) 사이에는 원웨이클러치(9)가 개재되어 정회전시 상기 모터측피동기어(7)에서 출력축(OUT)을 향한 일 방향의 동력 전달만 가능하도록 되어 있다.
A one-way clutch 9 is interposed between the motor-side driven gear 7 and the output shaft OUT so that power can be transmitted only in one direction from the motor-side driven gear 7 toward the output shaft OUT have.

따라서, 엔진(E)으로부터의 동력이 출력축(OUT)을 통해 구동륜으로 제공되어 차량이 전진하는 상황에서는 상기 원웨이클러치(9)에 의해 엔진의 동력이 상기 모터측피동기어(7)로 전달되지 않게 되고, 상기 모터(M)로부터의 동력이 출력축(OUT)으로 제공되어 차량이 전진하는 상황에서는 모터로부터의 동력이 상기 원웨이클러치(9)를 통해 출력축(OUT)으로 전달되는 것이다.
Therefore, when the power from the engine E is supplied to the drive wheel through the output shaft OUT and the vehicle advances, the power of the engine is transmitted to the motor-side driven gear 7 by the one-way clutch 9 And the power from the motor M is transmitted to the output shaft OUT through the one-way clutch 9 in a state where the power from the motor M is supplied to the output shaft OUT and the vehicle advances.

상기 클러치수단(CL)은 일측 방향으로는 상기 엔진측피동기어(3)를 상기 출력축(OUT)에 동기시켜서 고정시켰다가 해제하는 상태를 전환할 수 있도록 하는 동기치합식 싱크로기구(CL-S)와, 타측 방향으로는 상기 모터측피동기어(7)를 상기 출력축(OUT)에 고정시켰다가 해제하는 상태를 전환할 수 있도록 구성된 도그클러치(CL-D)로 구성될 수 있다.
The clutch means CL has a synchromesh type synchromesh mechanism CL-S for synchronizing the engine-side driven gear 3 with the output shaft OUT in one direction, And a dog clutch CL-D configured to switch a state in which the motor-side driven gear 7 is fixed to the output shaft OUT and released in the other direction.

물론, 상기 클러치수단(CL)은 다른 실시예로, 일측 방향으로는 상기 엔진측피동기어(3)를 상기 출력축(OUT)에 동기시켜서 고정시켰다가 해제하는 상태를 전환할 수 있도록 하고, 타측 방향으로는 상기 모터측피동기어(7)를 동기시켜서 상기 출력축(OUT)에 고정시켰다가 해제하는 상태를 전환할 수 있도록 양쪽 모두 동기치합식 싱크로기구로 구성될 수도 있을 것이다.
Of course, the clutch means CL may, in another embodiment, switch the state in which the engine-side driven gear 3 is fixed in synchronism with the output shaft OUT in the one direction and released, Side synchromesh mechanism such that the motor-side driven gear 7 is synchronized with the output shaft (OUT) so that the state of releasing the motor-driven driven gear 7 can be switched.

상기 클러치수단(CL)이 엔진측피동기어(3)를 출력축(OUT)에 연결하는 구성은 항상 동기치합식 싱크로기구를 사용하고, 모터측피동기어(7)를 출력축(OUT)에 연결하는 구성은 도그클러치로도 사용할 수 있는 이유는, 상기 모터측피동기어(7)를 출력축(OUT)에 연결하는 경우는 후진을 구현하기 위한 경우이므로, 출력축(OUT)이 정지한 상태에서 상기 모터측피동기어(7)와 출력축(OUT)을 연결하는 것이 가능하기 때문이고, 상기 엔진측피동기어(3)를 출력축(OUT)에 연결하는 경우는 EV주행 중 하이브리드모드로의 전환 등이 있어서 출력축(OUT)과 엔진측피동기어(3) 속도의 동기화가 필요하기 때문이다.
The configuration in which the clutch means CL connects the engine side driven gear 3 to the output shaft OUT always uses a synchronous engagement type synchromesh mechanism and connects the motor side driven gear 7 to the output shaft OUT The reason why the motor-side driven gear 7 can be used also as a dog clutch is that when the motor-side driven gear 7 is connected to the output shaft OUT, When the engine side driven gear 3 is connected to the output shaft OUT, there is a shift to the hybrid mode during EV traveling and the like so that the output shaft OUT ) And the speed of the engine-side driven gear 3 need to be synchronized.

한편, 상기 엔진측구동기어(1)는 상기 엔진측피동기어(3)보다 직경이 크게 형성되고, 상기 모터측구동기어(5)는 상기 모터측피동기어(7)보다 직경이 작게 형성되도록 구성하여, 엔진(E)에 의해 차량이 구동될 때에는 엔진의 동력을 오버드라이브 상태로 구동륜에 전달하도록 하여 차량의 고속 주행에 주로 엔진이 사용되도록 하고, 모터(M)에 의해 차량이 구동될 때에는 모터의 동력을 감속하여 토크를 증대시켜서 출력시킴으로써 차량의 저속 성능을 담당할 수 있도록 구성함으로써, 엔진과 모터의 토크특성이 상호 보완적으로 작용하여, 전체적으로 차량의 연비를 향상시킬 수 있도록 구성하고 있다.
On the other hand, the engine-side drive gear 1 is formed to be larger in diameter than the engine-side driven gear 3, and the motor-side drive gear 5 is formed to have a diameter smaller than that of the motor- When the vehicle is driven by the engine (E), the engine is transmitted to the drive wheel in an overdrive state so that the engine is mainly used for high-speed travel of the vehicle. When the vehicle is driven by the motor (M) So that the torque characteristics of the engine and the motor complement each other and the fuel economy of the vehicle as a whole can be improved.

상기 입력축(IN)과 엔진의 엔진회전축(13) 사이에는 상기 입력축(IN)으로의 동력을 단속할 수 있도록 엔진클러치(11)가 구비된 구조이다.
An engine clutch 11 is provided between the input shaft IN and the engine rotation shaft 13 so as to intermittently transmit power to the input shaft IN.

또한, 본 실시예는 상기 엔진회전축(13)에 구비된 발전용구동기어(15)와, 상기 엔진회전축(13)에 동심축을 이루어 회전 가능하게 설치되어 제너레이터(G)를 회전시키도록 연결된 발전용피동기어(17)와; 상기 엔진회전축(13)에 평행하게 배치되고 상기 발전용구동기어(15)에 치합되는 제1매개기어(19)와 상기 발전용피동기어(17)에 치합되는 제2매개기어(21)를 구비한 아이들러축(23)을 더 구비하고 있어서, 상기 엔진으로부터의 동력에 의해 상기 제너레이터(G)에서 지속적으로 전기가 발생될 수 있도록 되어 있다.
The present embodiment also includes a power generation drive gear 15 provided on the engine rotation shaft 13 and a power generation drive gear 15 mounted on the engine rotation shaft 13 so as to be rotatable, A driven gear 17; A first intermediate gear 19 disposed in parallel to the engine rotation shaft 13 and engaged with the power generation drive gear 15 and a second intermediate gear 21 meshing with the power generation driven gear 17 And further includes an idler shaft 23 so that electricity can be continuously generated in the generator G by the power from the engine.

상기와 같이 제너레이터(G)에서 발생된 전기는 배터리로 저장되고, 상기 배터리의 전기는 상기 모터(M)로 공급될 수 있도록 구성되어 있다.
As described above, the electricity generated by the generator G is stored as a battery, and the electricity of the battery is supplied to the motor M.

도 2는 본 발명의 실시예가 엔진모드를 구현하고 있는 상태로서, 상기 클러치수단(CL)에 의해 상기 엔진측피동기어(3)를 상기 출력축(OUT)에 연결하여, 엔진으로부터의 동력이 엔진클러치(11)와 입력축(IN)을 거쳐 엔진측구동기어(1)와 엔진측피동기어(3) 및 출력축(OUT)을 통해 인출되고 있으며, 상기 원웨이클러치(9)에 의해 상기 모터측피동기어(7)와 모터측구동기어(5) 및 모터(M)로는 엔진(E)으로부터의 회전력이 전달되지 않는다. 즉 모터와 관련된 부품들을 구동하기 위한 드래그가 없어서 엔진의 연비가 향상되게 된다.
FIG. 2 is a state in which the embodiment of the present invention implements an engine mode, in which the clutch means CL connects the engine-side driven gear 3 to the output shaft OUT, Side driven gear 1 and the engine-side driven gear 3 and the output shaft OUT via an input shaft 11 and an input shaft IN, The rotational force from the engine E is not transmitted to the motor 7, the motor side drive gear 5, and the motor M. [ That is, there is no drag for driving the parts related to the motor, so that the fuel efficiency of the engine is improved.

참고로, 본 실시예의 도면에서는 출력축(OUT)에 출력기어(27)를 구비하여 별도의 새로운 동력인출축(25)을 연결하고 있으나, 이는 편의상 표시한 것일 뿐 이 동력인출축(25) 대신에 바로 디퍼렌셜 등이 연결될 수 있음은 물론이다.
For reference, in the embodiment of the present invention, an output gear 27 is provided on the output shaft OUT and a new power take-off shaft 25 is connected to the power take-out shaft 25. However, It is a matter of course that the differential can be connected directly.

도 3은 모터(M)만에 의해 차량이 구동되는 EV모드를 구현하는 상태를 도시한 것으로서, 상기 클러치수단(CL)은 중립상태로 해제되어 있고, 상기 원웨이클러치(9)가 상기 모터측피동기어(7)로부터 출력축(OUT)으로의 동력은 전달하도록 되어 있으므로, 상기 모터(M)로부터의 구동력은 상기 출력축(OUT)으로 전달되어 차량의 EV모드 주행이 이루어진다.
3 shows a state in which an EV mode in which a vehicle is driven by only a motor M is implemented and in which the clutch means CL is released to a neutral state and the one- The power from the driven gear 7 to the output shaft OUT is transmitted so that the driving force from the motor M is transmitted to the output shaft OUT to drive the vehicle in the EV mode.

이때, 상기 클러치수단(CL)이 중립이므로 상기 엔진측피동기어(3)가 상기 출력축(OUT)과 연결되지 않아서, 상기 모터의 회전력이 출력축(OUT)을 통해 인출되어 EV모드 주행이 이루어지는 동안, 상기 엔진측피동기어(3)와 엔진측구동기어 및 입력축은 회전하지 않게 되므로 모터의 회전력이 불필요하게 낭비되는 것을 방지하여, 궁극적으로 차량의 연비 향상에 기여할 수 있게 된다.
At this time, since the clutch means CL is neutral, the engine-side driven gear 3 is not connected to the output shaft OUT, so that the rotational force of the motor is drawn out through the output shaft OUT, The engine-side driven gear 3, the engine-side drive gear, and the input shaft do not rotate, thereby preventing unnecessary waste of the rotational force of the motor and ultimately contributing to improvement in fuel efficiency of the vehicle.

한편, 후진을 상기 모터(M)로부터의 동력으로 구현하는 경우에는, 모터를 역회전시키므로 상기 원웨이클러치(9)에 의해 동력이 출력축(OUT)으로 전달되지 않는 것에 대비하여, 상기 클러치수단(CL)으로 상기 모터측피동기어(7)를 출력축(OUT)에 연결해야 한다.
On the other hand, when the reverse rotation is implemented by the power from the motor M, the power is not transmitted to the output shaft OUT by the one-way clutch 9 because the motor is rotated in reverse, CL, the motor-side driven gear 7 must be connected to the output shaft OUT.

도 4는 하이브리드모드로서, 상기 클러치수단(CL)으로 상기 엔진측피동기어(3)를 상기 출력축(OUT)에 연결하고 있는 상태에서 엔진(E)과 모터(M)를 함께 구동하는 경우로서, 엔진클러치(11)를 경유하여 상기 엔진측구동기어(1)와 엔진측피동기어(3)를 통한 엔진으로부터의 동력과 상기 모터로부터 상기 모터측구동기어(5)와 모터측피동기어(7) 및 원웨이클러치(9)를 경유한 동력이 상기 출력축(OUT)에서 함께 병합되어 출력됨으로써, 차량의 고부하 운전시에 대비할 수 있도록 하고 있다.
4 is a hybrid mode in which the engine E and the motor M are driven together in a state where the clutch means CL connects the engine side driven gear 3 to the output shaft OUT, Side driven gear 7 and the motor-side driven gear 7 from the engine via the engine-side drive gear 1 and the engine-side driven gear 3 via the engine clutch 11, And the one-way clutch 9 are coupled together at the output shaft OUT to be output at the time of a high load operation of the vehicle.

도 5는 시리즈모드로서, 상기 엔진클러치(11)를 해제한 상태에서 엔진(E)과 모터(M)를 모두 구동하고 있는 상황이며, 엔진으로부터의 동력으로 상기 제너레이터(G)를 구동하여 발생된 전기를 배터리로 공급함과 아울러 상기 배터리로부터의 전기로 상기 모터를 구동하여 차량이 구동되도록 함으로써, 엔진은 발전에만 동력을 제공하고, 모터는 차량의 구동에만 동력을 제공하는 시리즈모드를 구현할 수 있는 것이다.
5 is a series mode showing a state in which both the engine E and the motor M are driven in a state in which the engine clutch 11 is disengaged, The engine is able to provide power only for power generation and the motor can implement a series mode in which power is supplied only to the drive of the vehicle by supplying electricity to the battery and driving the motor by driving the motor with electricity from the battery .

여기서, 상기 클러치수단(CL)은 상기 엔진측피동기어(3)를 상기 출력축(OUT)과 연결 상태를 차단하여 상기 입력축(IN)의 회전을 방지함으로써, 시리즈모드에서의 연비 향상을 꾀할 수 있다.
Here, the clutch means CL prevents the rotation of the input shaft IN by interrupting the connection state of the engine-side driven gear 3 with the output shaft OUT, thereby improving the fuel economy in the series mode .

참고로, 도 2 내지 도 5에서 상대적으로 굵게 표시된 부분이 동력이 흐르는 부분임을 나타내고 있다.
For reference, in FIGS. 2 to 5, a relatively bold portion indicates that the power flows.
