하이브리드 차량의 변속기 {TRANSMISSION OF HYBRID VEHICLE}Transmission of hybrid vehicle {TRANSMISSION OF HYBRID VEHICLE}

본 발명은 하이브리드 차량의 변속기에 관한 것으로서, 보다 상세하게는, 두 개의 클러치가 적용된 하이브리드 차량의 변속기에 관한 것이다.
The present invention relates to a transmission of a hybrid vehicle, and more particularly, to a transmission of a hybrid vehicle to which two clutches are applied.

일반적으로 하이브리드 차량은 석유 연료를 사용하는 엔진과 배터리를 동력원으로 사용하는 모터를 함께 장착하여 연비를 높이고 배기 가스를 절감시켜 환경을 보호하기 위한 차량이다.In general, a hybrid vehicle is a vehicle for protecting the environment by increasing fuel economy and reducing exhaust gas by installing an engine using petroleum fuel and a motor using a battery as a power source.

이러한 종래 하이브리드 차량은, 도 1에 도시된 바와 같이, 크게 동력을 발생시키는 엔진(E')과; 모터(M'), 엔진 클러치(110), 차동 기어(D') 등이 내장되어 변속을 하기 위한 변속기(T')와; 변속기(T')와 연결된 휠(W')로 구성된다.This conventional hybrid vehicle, as shown in Figure 1, the engine (E ') for generating a large power; A transmission (T ') for shifting by including a motor (M'), an engine clutch (110), a differential gear (D '), and the like; It consists of a wheel W 'connected to the transmission T'.

엔진 클러치(110)는 엔진(E')과 접합 또는 해제되고, 이 때 엔진(E')은 벨트로 하이브리드 시동 모터 및 발전기(Hybrid Starter & Generator, 이하 HSG라고 함, H')와 연결되어 하이브리드 모드(HEV) 모드시 HSG(H')에 의해 재가동된다.The engine clutch 110 is coupled to or released from the engine E ', and at this time, the engine E' is connected to a hybrid starter and generator (HSG, hereinafter referred to as HSG) by a belt. In the HEV mode, it is restarted by the HSG (H ').

모터(M')는 변속기(T')의 내부에 내장되어, 차량 구동시 엔진(E')의 동력을 보조하며, 회생 제동시 배터리(B')를 충전시키는 역할을 한다. 이 때, 모터(M')의 일측에는 엔진 클러치(110)가 엔진(E')의 구동축(E1')과 동일축상에 연결되고, 타측에는 기계식 오일 펌프(130)가 연결되어 있다.The motor M 'is embedded in the transmission T' to assist the engine E 'when driving the vehicle and to charge the battery B' during regenerative braking. At this time, the engine clutch 110 is connected to one side of the motor M 'on the same axis as the drive shaft E1' of the engine E ', and the mechanical oil pump 130 is connected to the other side.

한편, 변속기(T')의 외부에는 엔진 클러치(110)가 오프(Off)되거나 슬립시 기계식 오일 펌프(130)가 엔진(E')과 직결되어 있지 않아 제 기능을 하지 못하는 경우를 대비하여 전동식 오일 펌프(135)가 장착되어 있다. On the other hand, the engine clutch 110 is off (Off) or the mechanical oil pump 130 is not directly connected to the engine (E ') when the slip on the outside of the transmission (T') in case of the electric function The oil pump 135 is mounted.

그런데, 이러한 종래 하이브리드 차량에 있어서는, 저속 장 등판시 엔진 클러치(110)가 슬립하면서 차량이 주행되는데, 이 때 HSG(H')의 용량이 작아 배터리(B')의 충전상태(State Of Charge, SOC) 관리가 어려워 모터(M')가 원활히 동력을 보조하기 어려울 뿐만 아니라, 엔진 클러치(110)가 과도하게 발열되어 연비가 저하되는 문제점이 있다.By the way, in such a conventional hybrid vehicle, the vehicle is driven while the engine clutch 110 slips during low-speed climbing, and at this time, the capacity of the HSG (H ') is small, so that the state of charge of the battery B' (State Of Charge, The SOC is difficult to manage, so that the motor M 'is difficult to smoothly assist the power, and the engine clutch 110 is excessively heated to lower fuel economy.

이 때, 상기와 같은 문제점을 해결하기 위해 HSG(H')의 용량이 큰 사양으로 장착할 수도 있겠으나, 이러한 경우 HSG(H')를 탑재하기 어렵고, 벨트의 용량에 한계가 있는 문제점이 있다.
At this time, in order to solve the above problems, the capacity of the HSG (H ') may be mounted with a large specification, but in this case, there is a problem in that it is difficult to mount the HSG (H') and the capacity of the belt is limited. .

따라서, 본 발명의 목적은 내부에 두 개의 클러치를 적용하여 저속 장 등판시 하나의 클러치는 접합되고 다른 하나의 클러치가 슬립되도록 구성함으로써 필요한 경우 모터를 적절하게 이용하여 발전할 있는 하이브리드 차량의 변속기를 제공하는 것이다. Accordingly, an object of the present invention is to apply two clutches inside so that one clutch is coupled and the other clutch slips at low speed climbing, so that the transmission of the hybrid vehicle can be generated by appropriately using a motor if necessary. To provide.

상기 목적은 본 발명의 하이브리드 차량의 변속기에 따라, 제1 회전축 및 제2 회전축이 마련된 모터와; 엔진의 구동축과 상기 모터의 제1 회전축 사이의 제1 축 상에 연결되는 제1 클러치와; 상기 모터의 제2 회전축과 전동식 오일 펌프 사이의 제2 축 상에 연결되는 제2 클러치를 포함하여, 저속 장 등판시 상기 제1 클러치는 접합되고, 상기 제2 클러치는 슬립되는 것에 의해 달성된다.The above object is, according to the transmission of the hybrid vehicle of the present invention, a motor provided with a first rotary shaft and a second rotary shaft; A first clutch connected on a first shaft between a drive shaft of an engine and a first rotation shaft of the motor; And a second clutch connected on a second shaft between the second rotational shaft of the motor and the electric oil pump, such that the first clutch is engaged and the second clutch is slipped during low speed climbing.

여기서, 상기 제1 클러치 및 상기 제2 클러치는 상기 모터를 사이에 두고 서로 편심되는 위치에 마련된 것이 바람직하다.Here, it is preferable that the first clutch and the second clutch are provided at positions eccentric with each other with the motor interposed therebetween.

상기 모터의 제2 회전축에는 기계식 오일 펌프가 연결되며, 상기 기계식 오일 펌프는 상기 제1 클러치가 접합 상태인 경우 회전수가 아이들(IDLE) 이상인 것이 좋다.A mechanical oil pump is connected to the second rotating shaft of the motor, and the mechanical oil pump may have a rotation speed greater than or equal to idle when the first clutch is engaged.

이 때, 상기 제1 축에는 상기 제1 클러치, 상기 모터, 유성 기어, 변속 클러치 및 브레이크가 마련된 것이 바람직하다.At this time, it is preferable that the first shaft is provided with the first clutch, the motor, the planetary gear, the shift clutch, and the brake.

상기 엔진에는 하이브리드 시동 모터 및 발전기(Hybrid Starter & Generator, HSG)가 연결되지 않으며, 하이브리드(HEV) 모드인 경우, 상기 모터가 구동되어 상기 제1 클러치를 접합시킴으로써 상기 엔진을 재가동시키는 것이 바람직하다. A hybrid starter and generator (HSG) is not connected to the engine, and in the hybrid mode, the motor is driven to restart the engine by engaging the first clutch.

상기 제1 클러치 및 상기 제2 클러치는 습식 클러치인 것이 좋다.
Preferably, the first clutch and the second clutch are wet clutches.

이상 설명한 바와 같이, 본 발명에 따르면, 두 개의 클러치를 적용하여 저속 장 등판시 하나의 클러치는 접합되고 다른 하나의 클러치가 슬립되도록 구성함으로써 필요한 경우 모터를 적절하게 이용하여 발전할 있는 하이브리드 차량의 변속기가 제공된다.
As described above, according to the present invention, a transmission of a hybrid vehicle in which two clutches are applied so that one clutch is joined and the other clutch slips during low climbing, the other clutch can be properly generated by using a motor if necessary. Is provided.

2 is a view schematically illustrating a configuration diagram of a hybrid vehicle to which a transmission according to the present invention is applied.
3 schematically illustrates a configuration connected on a second axis of the transmission of FIG. 2;

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 변속기가 적용된 하이브리드 차량의 구성도를 개략적으로 도시한 도면이다. 2 is a diagram schematically illustrating a configuration of a hybrid vehicle to which a transmission according to the present invention is applied.

본 발명에 따른 변속기(T)가 적용된 하이브리드 차량은, 도 2에 도시된 바와 같이, 크게 동력을 발생시키는 엔진(E)과; 모터(M), 제1 클러치(10), 제2 클러치(20), 차동 기어(D) 등이 내장되어 변속을 하기 위한 변속기(T)와; 변속기(T)와 연결된 휠(W)로 구성된다.Hybrid vehicle to which the transmission (T) according to the present invention is applied, as shown in Figure 2, the engine (E) for generating a large power; A transmission (T) for shifting incorporating a motor (M), a first clutch (10), a second clutch (20), a differential gear (D), and the like; It is composed of a wheel (W) connected to the transmission (T).

엔진(E)은 동력을 발생시키기 위한 것으로서, 구동축(E1)이 제1 클러치(10)와 제1 축(X)상에서 직결된다.The engine E is for generating power, and the drive shaft E1 is directly connected to the first clutch 10 and the first shaft X.

이 때, 엔진(E)에는 종래와 달리 하이브리드 시동 모터 및 발전기(Hybrid Starter & Generator, 이하 HSG라고 함)가 연결되지 않으며, 하이브리드(HEV) 모드인 경우, 모터(M)가 구동되어 상기 제1 클러치(10)를 접합시킴으로써 엔진(E)을 재가동시키게 된다. 즉, 본 발명에서는 종래의 HSG(H')를 삭제함으로써 제조 원가가 절감될 뿐만 아니라, 벨트의 소음이 제거되어 NVH 성능이 향상되는 이점이 있다. At this time, unlike the prior art, the engine E is not connected to a hybrid starter and a generator (Hybrid Starter & Generator, hereinafter referred to as HSG), and in the hybrid (HEV) mode, the motor (M) is driven to drive the first The engine E is restarted by engaging the clutch 10. That is, in the present invention, by eliminating the conventional HSG (H '), not only the manufacturing cost is reduced, but also the noise of the belt is removed, thereby improving the NVH performance.

변속기(T)는 엔진(E)의 회전 구동력을 전달받아 휠(W)에 전달하며, 그 내부에는 모터(M), 제1 클러치(10), 제2 클러치(20), 차동 기어(D) 등이 내장되어 있다.The transmission T receives the rotational driving force of the engine E and transmits it to the wheel W, and therein, the motor M, the first clutch 10, the second clutch 20, and the differential gear D therein. The back is built.

모터(M)는 엔진(E)과 함께 동력을 발생시키기 위한 것으로서, 제1 회전축(M1)과 제2 회전축(M2)을 가진다.The motor M is for generating power together with the engine E, and has a first rotating shaft M1 and a second rotating shaft M2.

제1 회전축(M1)은 모터(M)의 일측에 마련되어 제1 축(X)상에 제1 클러치(10)와 직결된다.The first rotation shaft M1 is provided at one side of the motor M and directly connected to the first clutch 10 on the first shaft X.

이 때, 제1 축(X)에는 제1 클러치(10), 모터(M), 유성 기어(미도시), 변속 클러치(미도시) 및 브레이크(미도시)가 마련된다.At this time, the first shaft 10 is provided with a first clutch 10, a motor M, a planetary gear (not shown), a shift clutch (not shown), and a brake (not shown).

제1 클러치(10)는 습식 클러치로서 변속기(T)의 내부에 마련되며, 엔진(E)의 구동축(E1)과 모터(M)의 제1 회전축(M1) 사이의 제1 축(X)에 연결됨으로써, 엔진 시동시 엔진(E)과 접합 또는 해제된다.The first clutch 10 is provided inside the transmission T as a wet clutch, and is provided on the first shaft X between the drive shaft E1 of the engine E and the first rotation shaft M1 of the motor M. FIG. By being connected, it is joined or released with the engine E at engine start-up.

제2 회전축(M2)은 모터(M)의 타측에 마련되어 기계식 오일 펌프(30)가 연결된다.
그리고 모터(M) 타측의 제2 축(Y) 상에는 제2 클러치(20)와 전동식 오일 펌프(35)가 직결된다. 즉, 제2 회전축(M2)에 연결된 기계식 오일 펌프(30)와 전동식 오일 펌프(35) 사이의 제2 축(Y) 상에 제2 클러치(20)가 구비된다. The second rotating shaft M2 is provided on the other side of the motor M to which the mechanical oil pump 30 is connected.
The second clutch 20 and the electric oil pump 35 are directly connected to the second shaft Y on the other side of the motor M. FIG. That is, the second clutch 20 is provided on the second shaft Y between the mechanical oil pump 30 and the electric oil pump 35 connected to the second rotation shaft M2.

이 때, 제2 축(Y)에는 제2 클러치(20), 아웃풋 샤프트(41), 트랜스퍼 드리븐 기어(42), 파킹 기어(43)가 마련된다.At this time, the second shaft 20 is provided with a second clutch 20, an output shaft 41, a transfer driven gear 42, and a parking gear 43.

즉, 제2 클러치(20)는 습식 클러치로서 변속기(T)의 내부에 마련되고, 제2 축(Y)상에 연결됨으로써, 슬립이 가능하여 발진시 이용된다. That is, the second clutch 20 is provided inside the transmission T as a wet clutch and is connected to the second shaft Y so that slip is possible and is used when starting.

또한, 제1 클러치(10) 및 제2 클러치(20)는 모터(M)와 기계식 오일 펌프(30)를 사이에 두고 서로 편심되는 위치에 마련되는 것이 바람직하다. 이에, 제1 클러치(10) 및 제2 클러치(20)가 변속기(T)의 내부에서 서로 동일 축상에 있으면 변속기(T)의 전장이 커져 차량에 탑재하기가 어려울 뿐만 아니라 유압 회로를 형성하는데 어려우나, 본 발명과 같이 제1 클러치(10) 및 제2 클러치(20)가 변속기(T)의 내부에서 서로 편심되는 위치에 마련되면 전장이 커지지 않으므로 차량에 탑재하기 쉬울 뿐만 아니라 유압 회로도 쉽게 형성할 수 있는 장점이 있다. In addition, it is preferable that the first clutch 10 and the second clutch 20 are provided at positions eccentric with each other with the motor M and the mechanical oil pump 30 interposed therebetween. Therefore, when the first clutch 10 and the second clutch 20 are coaxial to each other inside the transmission T, the overall length of the transmission T becomes large, making it difficult to mount on a vehicle and forming a hydraulic circuit. When the first clutch 10 and the second clutch 20 are provided at positions eccentric with each other in the transmission T as in the present invention, the electric field is not large, and thus it is easy to mount the vehicle and easily form a hydraulic circuit. There is an advantage.

이에, 차량이 저속 장 등판시 제1 클러치(10)는 접합되고 제2 클러치(20)는 슬립하면서 필요시 모터(M)를 이용한 발전이 가능하므로, 배터리(B)의 충전상태(State Of Charge, SOC) 관리에 유리하고, 연비가 향상되는 이점이 있다. Therefore, when the vehicle is mounted at a low speed, the first clutch 10 is coupled and the second clutch 20 slips, and power generation using the motor M can be performed when necessary, so that the state of charge of the battery B is maintained. , SOC) is advantageous, and the fuel economy is improved.

한편, 제1 클러치(10)가 접합 상태에서는 기계식 오일 펌프(30)의 회전수가 아이들(IDLE) 이상이기 때문에, 변속기(T)의 외부에 장착된 전동식 오일 펌프(35)의 사용 빈도를 줄일 수 있으므로, 전동식 오일 펌프(35)에 의한 전장 부하를 줄일 수 있으므로 연비 향상에 도움이 된다. On the other hand, since the rotation speed of the mechanical oil pump 30 is more than the idle IDLE when the first clutch 10 is in the engaged state, the frequency of use of the electric oil pump 35 mounted on the outside of the transmission T can be reduced. Therefore, the electric load by the electric oil pump 35 can be reduced, which helps to improve fuel efficiency.

이러한 구성에 의하여, 본 발명에 따르면, 두 개의 클러치를 적용하여 저속 장 등판시 하나의 클러치는 접합되고 다른 하나의 클러치가 슬립되도록 구성함으로써 필요한 경우 모터(M)를 적절하게 이용하여 발전할 있는 효과가 있다. According to the present invention, according to the present invention, by applying two clutches, one clutch is joined and the other clutch is slipped at low speed climbing, and the other clutch can be used to generate power by using the motor M appropriately if necessary. There is.

또한, 두 개의 클러치가 변속기의 내부에서 서로 편심되는 위치에 마련됨으로써, 변속기의 전장이 커지지 않으므로 차량에 탑재하기 쉬울 뿐만 아니라 유압 회로도 쉽게 형성할 수 있는 효과가 있다.
In addition, since the two clutches are provided at positions eccentric with each other inside the transmission, the overall length of the transmission is not large, so that it is easy to be mounted on the vehicle and the hydraulic circuit can be easily formed.
