오늘날 환경문제가 범세계적인 관심사가 되면서, 특히 자동차와 관련되는 배기가스의 저감과 연비 향상 등 환경을 생각하는 자동차 기술에 관한 연구가 활발히 진행되고 있는 바, 그 대표적인 예로서 하이브리드 전기 차량에 대한 연구를 들 수가 있다.As environmental issues become a global concern today, research on automobile technology that considers the environment such as reduction of fuel emissions and fuel efficiency related to automobiles is being actively carried out. I can lift it.

주지된 바와 같이, 하이브리드 차량은 두 가지 이상의 동력원을 사용하는 차량으로서, 일반적으로는 엔진과 모터를 사용하여 구동되는 하이브리드 전기 차량(HEV:Hybrid Electric Vehicle)을 말한다.As is well known, a hybrid vehicle is a vehicle using two or more power sources, and generally refers to a hybrid electric vehicle (HEV) driven using an engine and a motor.

최근 연비를 개선하고 보다 환경친화적인 제품을 개발해야 한다는 시대적 요청에 부응하여 하이브리드 전기 차량에 대한 연구가 더욱 활발히 진행되고 있다.In response to the recent demand for improving fuel economy and developing more environmentally friendly products, research on hybrid electric vehicles is being actively conducted.

이와 같은 하이브리드 전기 차량에 채택되는 동력 전달 계통으로서의 하이브리드 시스템으로는 크게 직렬 방식(series hybrid system)과 병렬 방식(parallel hybrid system), 그리고 스플릿 방식(split hybrid system)의 3가지로 나눌 수 있다. A hybrid system as a power transmission system adopted in such a hybrid electric vehicle can be largely divided into three types, a series hybrid system, a parallel hybrid system, and a split hybrid system.

여기서, 직렬 방식은 일반적인 전기 차량과 유사한 구조로서, 구동력은 전부 모터로부터 얻어지며, 엔진은 주행거리가 짧은 전기 차량의 단점을 보완하는 발전용으로서 탑재될 뿐이다.Here, the tandem type is a structure similar to that of a general electric vehicle, and the driving force is all obtained from the motor, and the engine is mounted only for power generation to compensate for the shortcomings of the electric vehicle having a short driving distance.

이러한 직렬 방식은 동력/전력 변환과 교류/직류 변환시에 발생하는 변환 손실만큼 연비면에서 불리하지만 배기가스가 깨끗하다는 장점이 있다.This series method is disadvantageous in terms of fuel efficiency as the conversion loss generated during power / power conversion and AC / DC conversion, but has an advantage that the exhaust gas is clean.

그리고, 병렬 방식은 엔진에 의한 주행을 기본으로 하고 엔진의 효율이 낮은 저속 운전시나 가속시 등에서 모터로 구동력을 보조한다. In addition, the parallel method is based on driving by the engine, and assists the driving force with the motor during low speed operation or acceleration during low engine efficiency.

이러한 병렬 방식은 가솔린 엔진과 전기 모터의 최적 작동영역을 이용함으로써 구동 시스템 전체의 연비를 향상시키고, 제동시는 모터로 동력을 회수함으로써 연비를 향상시킬 수 있다.This parallel method improves fuel economy of the entire drive system by utilizing the optimum operating area of the gasoline engine and the electric motor, and improves fuel economy by recovering power to the motor during braking.

그리고, 스플릿 방식은 상기 직렬 방식과 병렬 방식을 조합하여 동력 배분을 극대화한 것으로, 동력 분할(split)기구의 역할을 하는 유성기어세트를 포함한다.In addition, the split method maximizes the power distribution by combining the series method and the parallel method, and includes a planetary gear set serving as a power split mechanism.

종래 하이브리드 변속기는 엔진의 회전동력이 유성 기어 장치를 통해 변속되어 구동축에 전달되고, 이 구동축에 전달된 동력은 구동 기어와 치합된 종동 기어 및 추진축에 의해 구동 바퀴측에 전달된다.In the conventional hybrid transmission, the rotational power of the engine is shifted through the planetary gear device to be transmitted to the drive shaft, and the power transmitted to the drive shaft is transmitted to the drive wheel side by the driven gear and the propulsion shaft engaged with the drive gear.

그리고, 상기 유성 기어 장치에는 전기 발전기가 연결되어 주행중 감속하게 되면 엔진의 동력을 전달받아 전기를 발생시키게 된다. When the planetary gear device is connected to an electric generator and decelerates while driving, the engine receives power from the engine to generate electricity.

또한, 상기 전기 발전기에서 발생된 전기는 인버터를 통해 전기 충전기에 충 전되고, 이후 차량의 발진시나 가속시 상기 구동축을 회전시키는 전기 모터에 전기를 제공하게 된다.In addition, the electricity generated by the electric generator is charged to the electric charger through the inverter, and then provides electricity to the electric motor for rotating the drive shaft when the vehicle starts or accelerates.

물론, 상기 추진축에는 종동 기어 대신에 링기어가 구동기어와 연결되는 디퍼렌셜이 설치된 것도 있다.Of course, the propulsion shaft may have a differential in which a ring gear is connected to the drive gear instead of the driven gear.

그리고, 상기한 유성 기어 장치는 선기어가 상기 전기 발전기에 연결되고, 유성 기어 캐리어가 엔진측에 연결되며, 링기어가 구동축에 연결되어, 각각의 회전력을 제어함으로써 동력 전달의 방향과 속도비를 다르게 형성토록 되어 있다.In the planetary gear device, the sun gear is connected to the electric generator, the planetary gear carrier is connected to the engine side, and the ring gear is connected to the drive shaft, thereby controlling the rotational force to change the direction and speed ratio of the power transmission. It is supposed to be formed.

상기와 같이 구성된 종래 하이브리드 변속기는 차량의 발진 및 가속 주행시에는 전기 충전기에 충전된 전기에 의해 전기 모터가 회전되면서 엔진과 함께 구동축을 회전시킴으로써 차량의 발진 및 가속 출력을 높이게 된다.The conventional hybrid transmission configured as described above increases the oscillation and acceleration output of the vehicle by rotating the drive shaft together with the engine while the electric motor is rotated by the electricity charged in the electric charger during the vehicle starting and accelerating.

반면, 차량의 감속 주행시에는 구동축 및 추진축으로의 동력 전달은 줄어들고 엔진의 동력이 전기 발전기로 전달되어 전기를 발생시키고, 이렇게 발생된 전기는 인버터를 통해 전기 충전기에 충전된 후, 차량의 주행 상태가 변하게 되면 전기 모터에 제공되게 된다.On the other hand, when the vehicle decelerates, power transmission to the drive shaft and the propulsion shaft is reduced, and power of the engine is transmitted to the electric generator to generate electricity. The generated electricity is charged to the electric charger through the inverter, and then the driving state of the vehicle is If changed, it is provided to the electric motor.

상기 전기 모터 중 영구자석 모터는 도 2에 도시한 바와 같이 1개의 스테이터(100)와 로터(101)를 갖고, 소프트 및 하드타입의 하이브리드 차량 엔진의 비효율구간(연비 및 배기가스)에서 동력을 보조하도록 구성된다.As shown in FIG. 2, the permanent magnet motor of the electric motor has one stator 100 and a rotor 101, and assists power in an inefficient section (fuel efficiency and exhaust gas) of a soft and hard type hybrid vehicle engine. It is configured to.

상기 모터는 모터의 발생토크를 구동력으로 사용하기때문에 통상적으로 구동모터라 지칭된다.The motor is commonly referred to as a drive motor because it uses the generated torque of the motor as a driving force.

또한, 회생제동시나 충전량(state of charge;soc)이 부족할 경우에는 발전기 로도 사용되어 충전의 역할을 하게 된다.In addition, when regenerative braking or when the state of charge (soc) is insufficient, it is also used as a generator to play a role of charging.

그러나, 상기의 모터시스템은 그 부피가 크기때문에 항상 탑재성의 문제가 발생되어, 결국에는 모터의 크기를 적정선에서 결정해야하기 때문에 모터의 토크손실 즉 스테이터의 축방향 크기 감소로 이어져 하이브리드 차량에서 모터링(motoring) 및 충전(charging) 효율이 저하되고, 소프트 하이브리드 차량에서는 충전과 토크 어시스트를 동시에 병행하지 못하기 때문에 배터리의 충방전 효율도 저하되는 문제점이 있다.However, since the motor system has a large volume, a mountability problem always occurs. Therefore, since the size of the motor must be determined at an appropriate line, it leads to a torque loss of the motor, that is, a reduction in the axial size of the stator. (motoring) and charging (charging) efficiency is lowered, and in the soft hybrid vehicle, there is a problem that the charge and discharge efficiency of the battery is also lowered because it is not possible to simultaneously charge and torque assist.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 세퍼레이터에 의해 두개로 분리된 스테이터와, 직경이 다른 2개의 로터로 구성되고, 변속기 케이스에 삽입고정된 링기어가 제1로터와 기어로 연결되고, 제1로터가 제2로터와 기어로 연결됨으로써, 기어비 및 반경이 다른 2개의 로터를 이용하여 초기 토크 결정의 자유도를 높일 수 있고, 모터구동시에 함께 구동되는 2개의 로터가 충전 및 토크어시스트를 동시에 수행하고, 충전량을 일정 수준까지 유지하도록 하여 하이브리드 배터리의 수명을 연장하고, 오르막길을 오르거나 WOT(Wide Open Throttle) 등과 같은 경우에는 큰 토크를 내는 로터로 변환하여 토크를 사용할 수 있도록 한 하이브리드 차량용 모터 감속기를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and consists of two stators separated by a separator and two rotors of different diameters, and a ring gear inserted and fixed in the transmission case is connected to the first rotor and the gear. Since the first rotor is connected to the second rotor by gears, the two rotors having different gear ratios and radii can increase the degree of freedom of initial torque determination, and the two rotors driven together when the motor is driven are charged and torque assisted. Hybrid to extend the life of the hybrid battery by maintaining the charge level up to a certain level, and to use the torque by converting to a rotor that produces a large torque in case of climbing uphill or WOT (Wide Open Throttle) The purpose is to provide a motor reducer for a vehicle.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 하이브리드 차량용 모터 감속기의 일실시예를 나타내는 장치구성도이다.1 is a block diagram showing an embodiment of a motor speed reducer for a hybrid vehicle according to the present invention.

본 발명은 기어비 및 반경이 서로 다른 두개의 로터(10,11)를 채용함으로써, 초기 토크결정의 자유도가 높고, 충전 및 토크어시스트를 동시에 수행하여 충전량을 일정수준까지 유지할 수 있도록 한 점에 주안점이 있다.The present invention focuses on the fact that by employing two rotors 10 and 11 having different gear ratios and radii, the degree of freedom of initial torque determination is high, and the charging amount can be maintained at a constant level by simultaneously performing charging and torque assist. have.

본 발명은 세퍼레이터(12)에 의해 두개로 분리된 제1 및 제2스테이터(13,14)와, 제1 및 제2스테이터(13,14)를 사이에 두고 직경이 다른 제1 및 제2로터(10,11) 로 구성되어 있다. According to the present invention, the first and second stators 13 and 14 separated into two by the separator 12 and the first and second rotors having different diameters with the first and second stators 13 and 14 interposed therebetween. It consists of (10,11).

상기 제1 및 제2스테이터(13,14)는 3상 와이어(15)에 의해 인버터(16)와 연결되어 있고, 인버터(16)는 모터제어유닛(MCU)(17) 및 배터리(18)와 전기적으로 연결되어 있다. The first and second stators 13 and 14 are connected to the inverter 16 by a three-phase wire 15, and the inverter 16 is connected to a motor control unit (MCU) 17 and a battery 18. It is electrically connected.

변속기 케이스에는 링기어(20)가 삽입되어 고정되고, 링기어(20)가 제1로터(10)와 유성기어(19)에 의해 연결되고, 제1로터(10)는 다시 제2로터(11)와도 유성기어(19)에 의해 연결되는 구조로 되어 있다.The ring gear 20 is inserted and fixed to the transmission case, and the ring gear 20 is connected by the first rotor 10 and the planetary gear 19, and the first rotor 10 is again the second rotor 11. ) Is also connected by a planetary gear (19).

상기 제1로터(10)는 캐리어 역할을 하고, 제1로터(10)에서 축방향으로 형성된 회전축(21)에 유성기어(19)가 축설되게 되며, 상기 제2로터(11)는 선기어 역할을 하며, 그 선기어부(22)에 유성기어(19)가 치합되고, 이때의 유성기어(19)는 링기어(20)와 제2로터(11) 사이에서 맞물려 회전하게 된다.The first rotor 10 serves as a carrier, and the planetary gear 19 is installed on the rotation shaft 21 formed in the axial direction of the first rotor 10, and the second rotor 11 serves as a sun gear. The planetary gear 19 is engaged with the sun gear 22, and the planetary gear 19 is engaged between the ring gear 20 and the second rotor 11 to rotate.
