본 발명은 병렬형 하이브리드 동력전달구조에 관한 것으로서, 보다 상세하게는 종래의 변속기들을 사용하여 간단한 구성으로 전기차모드 및 하이브리드모드 등을 모두 구현할 수 있도록 하는 파워트레인 구조에 관한 기술이다.The present invention relates to a parallel hybrid power transmission structure, and more particularly, to a power train structure that can implement both an electric vehicle mode and a hybrid mode in a simple configuration using a conventional transmission.

종래 순수한 소프트타입 하이브리드 동력전달구조는 종전의 변속기들을 거 의 변경하지 않고 그대로 채용하면서, 모터를 추가함으로써, 엔진의 동력을 보조하고 잉여 동력으로 발전하여 배터리를 충전할 수 있도록 되어 있다.Conventionally, the pure soft type hybrid power transmission structure employs conventional transmissions as they are, without altering them, and adds a motor to assist the engine power and generate surplus power to charge the battery.

그러나 상기한 바와 같은 순수한 소프트타입 하이브리드 동력전달구조는 모터와 엔진의 동력 연결을 분리할 수 없어서, 연비나 배기가스 측면에서 유리한 모터만에 의한 전기차모드의 구현이 불가능한 문제점이 있었다.However, the pure soft type hybrid power transmission structure as described above has a problem in that it is impossible to separate the power connection between the motor and the engine, and thus the electric vehicle mode may not be realized by only the motor which is advantageous in terms of fuel economy or exhaust gas.

한편, 상기와 같은 순수한 전기차모드를 구현할 수 있도록 된 병렬형 하이브리드 파워트레인은 대체로 종전의 변속기를 그대로 채용하지 못하고 전체적으로 새로운 동력전달체계를 갖추어야 하는 경우가 많으며, 종전의 변속기를 그대로 채용하는 경우 파워트레인의 길이가 크게 증가되어 차량에의 탑재성이 불리하게 되는 경우가 많다.On the other hand, the parallel hybrid powertrain that can implement the pure electric vehicle mode as described above generally does not employ the conventional transmission as it is, it is often required to have a new power transmission system as a whole, and when adopting the conventional transmission as it is In many cases, the length of is greatly increased, and the mountability on the vehicle is disadvantageous.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 종래의 변속기를 그대로 채용하면서 간단한 구성으로 차량에의 탑재성을 양호하게 확보하면서도 순수한 전기차모드 및 하이브리드 모드 등 다양한 주행모드를 자유롭게 구사할 수 있도록 한 병렬형 하이브리드 동력전달구조를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, while adopting a conventional transmission as it is, it is possible to freely use a variety of driving modes such as pure electric vehicle mode and hybrid mode while ensuring good mountability to the vehicle with a simple configuration The purpose is to provide a parallel hybrid power transmission structure.

를 포함하여 구성된 것을 특징으로 한다.Characterized in that configured to include.

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 공통요소(1)가 엔진(3)에 연결되고 상기 공통요소(1)와의 동력전달상태를 각각 조절할 수 있도록 된 제1클러치(5)와 제2클러치(7)가 일체로 구비된 더블클러치(9)와; 상기 제1클러치(5)와 제2클러치(7) 중 어느 하나와 입력축(11)이 연결된 변속기(13)와; 한 요소는 고정되고 나머지 두 요소 중 어느 하나가 상기 제1클러치(5)와 제2클러치(7) 중 어느 하나에 연결된 유성기어세트(15)와; 상기 유성기어세트(15)의 고정되지 않은 두 요소 중 어느 하나와 상기 변속기(13)의 입력축(11)에 로터(17)가 연결된 모터(19)를 포함하여 구성된다.Referring to FIG. 1, in the embodiment of the present invention, the first clutch 5 and the second clutch in which the common element 1 is connected to the engine 3 and the power transmission state with the common element 1 can be adjusted respectively. A double clutch (9) integrally provided with (7); A transmission 13 to which one of the first clutch 5 and the second clutch 7 and the input shaft 11 are connected; A planetary gear set 15 in which one element is fixed and one of the other two elements is connected to any one of the first clutch 5 and the second clutch 7; It comprises one of the two non-fixed elements of the planetary gear set 15 and the motor 19 is connected to the rotor 17 of the input shaft 11 of the transmission (13).

상기 더블클러치(9)는 엔진(3)에 연결된 공통요소(1)의 내측에 제1클러치(5)와 제2클러치(7)가 배치되어 있어서, 상기 제1클러치(5)는 상기 변속기(13)의 입력축(11)에 연결되고, 상기 제2클러치(7)는 상기 유성기어세트(15) 의 캐리어에 연결된 구조이다.In the double clutch 9, the first clutch 5 and the second clutch 7 are disposed inside the common element 1 connected to the engine 3, so that the first clutch 5 is the transmission ( 13 is connected to the input shaft 11, the second clutch (7) has a structure connected to the carrier of the planetary gear set (15).

상기 유성기어세트(15)는 선기어가 고정되어 있으며, 상기 모터(19)의 로터(17)는 상기 유성기어세트(15)의 링기어와 상기 변속기(13)의 입력축(11)에 함께 연결되어 있어서, 결과적으로 상기 유성기어세트(15)의 링기어도 상기 변속기(13)의 입력축(11)에 연결되어 있는 구조이다.The planetary gear set 15 has a sun gear fixed thereto, and the rotor 17 of the motor 19 is connected to the ring gear of the planetary gear set 15 and the input shaft 11 of the transmission 13 together. As a result, the ring gear of the planetary gear set 15 is also connected to the input shaft 11 of the transmission 13.

특히, 상기 유성기어세트(15)는 상기 모터(19)의 로터(17) 내측공간에 위치하도록 구성하여 공간 활용도를 극대화하도록 하는 것이 바람직하다.In particular, the planetary gear set 15 is preferably configured to be located in the inner space of the rotor 17 of the motor 19 to maximize space utilization.

상기 변속기(13)는 종래의 자동변속기나, CVT(Continuously Variable Transmission), AMT(Automatic Manual Transmission) 등이 별도의 변경 없이 그대로 채용될 수 있다. The transmission 13 is a conventional automatic transmission, CVT (Continuously Variable Transmission), AMT (Automatic Manual Transmission) and the like can be employed as it is without modification.

본 실시예는 엔진(3)과 변속기(13) 사이에 상기 더블클러치(9)와 모터(19) 및 모터(19)의 로터(17) 내측에 구비된 유성기어세트(15)만을 포함하므로, 파워트레인의 길이가 크게 증대되지 않아 차량에의 탑재성을 우수하게 확보할 수 있다.Since the present embodiment includes only the double clutch 9 and the planetary gear set 15 provided inside the rotor 17 of the motor 19 and the motor 19 between the engine 3 and the transmission 13, Since the length of the power train is not greatly increased, the mountability to the vehicle can be excellently secured.

상기한 바와 같이 구성된 병렬형 하이브리드 동력전달구조의 몇가지 주행모드를 살펴보면 다음과 같다.Some driving modes of the parallel hybrid power transmission structure configured as described above are as follows.

전기차모드의 구현시에는 상기 더블클러치(9)의 제1클러치(5)와 제2클러치(7)는 모두 해제상태로 하고, 엔진(3)도 물론 작동하지 않으며, 상기 모터(19)에서만 동력을 발생시킨다.In the implementation of the electric vehicle mode, both the first clutch 5 and the second clutch 7 of the double clutch 9 are released, the engine 3 of course does not operate, and only the motor 19 is powered. Generates.

상기 모터(19)의 로터(17)는 상기 변속기(13)의 입력축(11)에 직접 연결되어 있으므로, 모터(19)에서 발생된 회전력은 그대로 변속기(13)로 공급되어 적절히 변속된 후 구동륜에 이르게 되며, 이때 변속기(13)는 대체로 저단 변속 상태에 있게 된다.Since the rotor 17 of the motor 19 is directly connected to the input shaft 11 of the transmission 13, the rotational force generated by the motor 19 is supplied to the transmission 13 as it is and is properly shifted to the driving wheel. In this case, the transmission 13 is generally in a low speed shift state.

가속시 등과 같은 경우에 사용되는 하이브리드모드의 경우에는, 상기 제1클러치(5)는 해제하고 제2클러치(7)를 결합하며, 상기 모터(19)와 엔진(3)에서 모두 동력을 발생한다.In the hybrid mode used in the case of acceleration, etc., the first clutch 5 is released, the second clutch 7 is coupled, and both the motor 19 and the engine 3 generate power. .

상기 엔진(3)에서 발생된 동력은 상기 제2클러치(7)를 통하여 상기 유성기어세트(15)의 캐리어로 공급되고, 선기어가 고정되어 있으므로 링기어를 통해 증속되어 상기 모터(19)의 로터(17)에서 출력되는 회전력과 함께 상기 변속기(13)의 입력축(11)으로 공급되게 된다.The power generated by the engine 3 is supplied to the carrier of the planetary gear set 15 through the second clutch 7, and the sun gear is fixed so that the power is increased through the ring gear to rotate the rotor of the motor 19. Along with the rotational force output from the (17) it is supplied to the input shaft 11 of the transmission (13).

이 경우 엔진(3)의 동력이 유성기어세트(15)에 의해 증속되어 변속기(13)로 공급되므로 엔진(3)의 회전수를 낮출 수 있어서, 연비향상에 기여할 수 있다.In this case, since the power of the engine 3 is increased by the planetary gear set 15 and supplied to the transmission 13, the rotation speed of the engine 3 can be lowered, thereby contributing to improved fuel economy.

정속주행 등과 같은 경우에 사용되는 엔진만에 의한 모드인 엔진모드에서는 상기 제1클러치(5)를 체결하고 상기 제2클러치(7)는 해제하며, 엔진(3)에서만 동력을 발생시킨다.In the engine mode, which is a mode by only the engine used in the case of constant speed driving or the like, the first clutch 5 is fastened, the second clutch 7 is released, and power is generated only in the engine 3.

따라서, 상기 엔진(3)에서 발생된 동력은 상기 제1클러치(5)를 통해 직접 상기 변속기(13)의 입력축(11)으로 공급되어, 종래의 일반적인 엔진과 변속기만의 차량과 같은 동력전달 경로를 가지게 된다.Therefore, the power generated by the engine 3 is directly supplied to the input shaft 11 of the transmission 13 through the first clutch 5, so that a power transmission path such as a vehicle of a conventional general engine and a transmission only. Will have

구동륜으로부터 역으로 입력되는 동력에 의해 회생제동작용을 할 때에는 상기 제1클러치(5)와 제2클러치(7)를 모두 해제하고, 엔진(3)은 작동하지 않으며, 상 기 모터(19)는 발전기로서 기능하여 발전된 전기를 배터리에 충전할 수 있도록 한다.When the regenerative braking action is performed by the power input back from the driving wheel, both the first clutch 5 and the second clutch 7 are released, and the engine 3 does not operate, and the motor 19 Functions as a generator to charge the battery with generated electricity.

구동륜에서 역으로 공급된 회전력은 상기 변속기(13)의 입력축(11)을 통해 상기 모터(19)의 로터(17)에 직접 공급되므로, 모터(19)는 입력되는 기계적인 에너지를 전기적 에너지로 바꾸어 배터리에 제공할 수 있게 되며, 이때 엔진(3)은 모터(19) 및 상기 변속기(13) 입력축(11)과는 격리되어 있어서 관성저항을 제공하지 않으므로, 회생제동효율을 높게 확보할 수 있다.Since the rotational force supplied back from the driving wheel is directly supplied to the rotor 17 of the motor 19 through the input shaft 11 of the transmission 13, the motor 19 converts the input mechanical energy into electrical energy. In this case, since the engine 3 is isolated from the motor 19 and the transmission 13 and the input shaft 11, the engine 3 does not provide an inertial resistance, thereby ensuring high regenerative braking efficiency.

엔진(3)의 시동시에는 상기 제2클러치(7)만 결합하여 모터(19)의 회전력이 링기어에서 캐리어로 감속되어 엔진(3)으로 공급됨으로써 강한 토크로 엔진(3)의 시동이 용이하게 이루어질 수 있도록 하며, 별도의 ISG(Integrated Starter Generator) 등을 필요로 하지 않게 된다.When the engine 3 is started, only the second clutch 7 is engaged, so that the rotational force of the motor 19 is decelerated from the ring gear to the carrier and supplied to the engine 3 so that the engine 3 can be easily started with strong torque. It can be made, and does not require a separate integrated starter generator (ISG).

이상과 같이 본 발명에 의하면, 종래의 변속기를 그대로 채용하면서 간단한 구성으로 차량에의 탑재성을 양호하게 확보하면서도 순수한 전기차모드 및 하이브리드 모드 등 다양한 주행모드를 자유롭게 구사할 수 있도록 하고, 엔진의 회전수를 낮출 수 있어서 연비를 향상시키고, 엔진의 시동을 용이하게 할 수 있다.As described above, according to the present invention, it is possible to freely use various driving modes such as pure electric vehicle mode and hybrid mode while ensuring good mountability to the vehicle with a simple configuration while adopting a conventional transmission as it is, and the engine speed is increased.
