Description

차량용 하이브리드 파워트레인{HYBRID POWERTRAIN FOR VEHICLE}Hybrid powertrain for vehicles {HYBRID POWERTRAIN FOR VEHICLE}

본 발명은 차량용 하이브리드 파워트레인에 관한 것으로서, 보다 상세하게는 동기치합식 변속메커니즘을 사용하는 하이브리드 파워트레인의 구성에 관한 기술이다.The present invention relates to a hybrid powertrain for a vehicle, and more particularly, to a technology for constructing a hybrid powertrain using a synchronizing shift mechanism.

동기치합식 변속 메커니즘(Synchromesh Type Shifting Mechanism)은 종래에 수동변속기나 AMT(Automated Manual Transmission), DCT(Dual Clutch Transmission)에 사용되는 변속 메커니즘으로서, 다른 변속 메커니즘에 비해 구성이 간단하고, 동력 전달 효율이 우수하며, 변속단을 유지하는 데에 별도의 동력이 소모되지 않는 장점이 있다.The Synchromesh Type Shifting Mechanism is a shifting mechanism conventionally used in a manual transmission, AMT (Automated Manual Transmission), or DCT (Dual Clutch Transmission), and has a simpler configuration than other shifting mechanisms and power transmission efficiency. This is excellent, and there is an advantage that separate power is not consumed to maintain the gear stage.

따라서, 하이브리드 차량의 구현에 있어서도 동기치합식 변속 메커니즘은 매우 유리한 측면이 있지만, 변속 시 동력이 단절되는 토크인터럽션(Torque Interruption)이 발생하는 등의 단점을 가지고 있다.Therefore, even in implementing a hybrid vehicle, the synchronizing shift mechanism has a very advantageous aspect, but has a disadvantage such as occurrence of a torque interruption in which power is cut off during shifting.

상기 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.The matters described as the background technology of the present invention are only for the purpose of improving the understanding of the background of the present invention, and should not be taken as an admission that they correspond to the prior art already known to those skilled in the art. It will be.
