본 발명은 하이브리드 차량의 변속장치에 관한 것이다.The present invention relates to a transmission of a hybrid vehicle.
통상적으로, 하이브리드 차량의 경우 도 1에 도시된 바와 같이 엔진과 모터를 변속기사이에 위치하여 엔진 구동시 모터를 거쳐서 변속기로 동력을 전달한다.Typically, in the case of a hybrid vehicle, as shown in FIG. 1, the engine and the motor are positioned between the transmission to transmit power to the transmission through the motor when the engine is driven.
그리고, 모터 구동시 엔진은 오프(Off)되고 모터의 구동력만 변속기로 전달되는 구조로 되어있다.When the motor is driven, the engine is turned off and only the driving force of the motor is transmitted to the transmission.
이러한 동력 전달계 구조의 문제점은 엔진룸의 용적이 부족하여 엔진 및 변속기, 모터의 설계에 많은 제한을 가져오게 되어 설계 자유도가 떨어지게 된다. The problem of the structure of the power transmission system is that the lack of the volume of the engine room brings a lot of restrictions on the design of the engine, transmission, and motor, and the design freedom is reduced.

제2 변속축은 2개의 축이 한 조를 이루며, 제1 변속축으로부터 각각 회전력을 전달받아 해당되는 기어 변속을 한다.The second transmission shaft is a pair of two shafts, each receives a rotational force from the first transmission shaft to the corresponding gear shift.
제2 변속축에는 제1 변속축에 각각 연결되는 변속 기어들과의 변속비 조합에 따라 설정된 보조 변속 기어들이 연결된다.Auxiliary transmission gears set according to a transmission ratio combination with transmission gears respectively connected to the first transmission shaft are connected to the second transmission shaft.
모터는 도 2에 도시된 바와 같이 제2 변속축 가운데 한 개의 축에 연결되며, 엔진을 보조하는 동력을 제공한다.The motor is connected to one of the second shift shafts as shown in FIG. 2 and provides power to assist the engine.
상기한 바와 같이 본 발명의 실시예는 하이브리드 차량용 변속장치에 관한 것으로, 기존의 수동 변속기에서 자동 변속기의 변속감을 얻기 위하여 최근에 활발히 연구되고 있는 이중 클러치 변속기(DCT ; Double Clutch Transmission)의 구조를 이용하여 하이브리드 차량용 변속기를 구성한다.As described above, an embodiment of the present invention relates to a transmission device for a hybrid vehicle, and utilizes a structure of a double clutch transmission (DCT; Double Clutch Transmission), which has been actively studied recently to obtain a shifting feeling of an automatic transmission in a conventional manual transmission. To form a transmission for the hybrid vehicle.
본 발명의 실시예에서 설명하는 하이브리드 차량용 변속기 구조 및 동력 전달 구조를 이용하여 엔진룸 배열의 효율적 배치가 가능해지며 각각의 구동 조건에 맞도록 기어비를 조작하고 엔진 및 모터의 동력 전달을 조절할 수 있다.By using the transmission structure and the power transmission structure for the hybrid vehicle described in the embodiment of the present invention, it is possible to efficiently arrange the engine room arrangement, and to adjust the gear ratio and adjust the power transmission of the engine and the motor according to the respective driving conditions.
이러한 이유로 보다 효율적인 구동 및 동력 전달 효과를 얻을 수 있으며 하이브리드 차량의 원래 목적인 높은 연비 성능을 얻을 수 있다.For this reason, more efficient driving and power transmission effects can be obtained, and high fuel economy performance, which is the original purpose of the hybrid vehicle, can be obtained.
그리고 엔진 오프(Off)상태에서도 에어컨 작동 등의 부수적 효과를 얻을 수가 있다.In addition, the side effects such as the operation of the air conditioner can be obtained even in the engine off state.
본 발명의 실시예에 따른 이중 클러치 변속기의 경우 모터는 짝수 기어단을 형성하는 샤프트와 직결한다.In the case of the dual clutch transmission according to the embodiment of the present invention, the motor is directly connected to the shaft forming the even gear stage.
도 3 내지 도 7은 본 발명의 실시예에 따른 하이브리드 차량의 동력 전달 상태를 도시한 도면이다.3 to 7 are diagrams illustrating a power transmission state of a hybrid vehicle according to an exemplary embodiment of the present invention.
통상적인 1속 주행의 경우에 대한 동력 전달 경로는 도 3에 도시된 바와 같다.The power transmission path for the conventional one speed travel case is as shown in FIG. 3.
1속 주행의 경우는 제1 클러치(Clutch A)만 작동하여 동력을 전달한다.In the case of the first speed driving, only the first clutch A operates to transmit power.
하이브리드 차량의 경우 초기 발진시나 큰 동력이 필요한 경우(등판, 초기 발진시) 엔진 출력뿐만 아니라 모터의 동력까지 사용한다.In the case of a hybrid vehicle, the engine power as well as the engine power is used when the initial start-up or when a large amount of power is required (back climbing, initial start-up).
통상적인 6속 주행(고속도로 고속 주행시)의 경우에 대한 동력 전달 경로는 도 4에 도시된 바와 같다.The power transmission path for the case of a typical six speed travel (at high speed and high speed travel) is as shown in FIG. 4.
6속 주행의 경우는 제2 클러치(Clutch B)만 작동하여 동력을 전달한다.In the case of 6-speed driving, only the second clutch B is operated to transmit power.
통상적인 시내 저속 주행과 같이 큰 동력이 필요하지 않는 경우는 엔진을 오프(Off)시키고 모터만의 동력으로 주행하며 이 경우에 대한 동력 전달 경로는 도 5에 도시된 바와 같다.When a large amount of power is not required, such as a typical downtown low speed driving, the engine is turned off and the vehicle is driven by the power of only the motor. In this case, the power transmission path is as shown in FIG. 5.
물론 시내 주행시에도 모터 동력만으로 주행하기에 동력이 부족한 경우는 엔진과 함께 차량을 구동하여 큰 출력을 낼 수 있도록 한다.Of course, even when driving in the city, if the power is insufficient to drive only by the motor power to drive the vehicle with the engine to produce a large output.
또한, 코스팅(내리막 주행시 또는 감속시) 주행시의 경우 도 6에 도시된 바와 같이 바퀴의 구동력을 모터로 전달하여 배터리에 재충전하는 조작을 실시한다.In the case of coasting (downhill driving or deceleration) driving, the driving force of the wheel is transmitted to the motor to recharge the battery as shown in FIG. 6.
엔진 오프(Off) 상태에서 에어컨 작동을 하려면 도 7에서와 같이 컴프레서를 구동하여 주어야 한다.To operate the air conditioner in the engine off state, the compressor must be driven as shown in FIG. 7.
이 경우는 모터에서 직접 에어컨 컴프레서를 구동하여 엔진 오프(Off)시에도 에어컨 성능을 발휘할 수 있도록 조작한다.In this case, the air conditioner compressor is driven directly from the motor to operate the air conditioner even when the engine is off.
상술한 바와 같이 본 발명에 따른 하이브리드 차량의 변속장치는 연비향상의 효과가 있으며, 엔진 오프시에도 에어컨 작동이 가능하고, 엔진룸을 효율적으로 배치할 수 있는 효과가 있다.As described above, the transmission of the hybrid vehicle according to the present invention has an effect of improving fuel economy, an air conditioner can be operated even when the engine is off, and an engine room can be efficiently arranged.
