Description

차량용 하이브리드 변속기{HYBRID TRANSMISSION FOR VEHICLE}[0001] HYBRID TRANSMISSION FOR VEHICLE [0002]

본 발명은 차량용 하이브리드 변속기에 관한 것으로서, 보다 상세하게는 4단 변속기 내부에 하이브리드용 모터를 추가하여 하이브리드용 CVT 변속기가 구현될 수 있는 차량용 하이브리드 변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a hybrid vehicle for a vehicle, and more particularly, to a hybrid vehicle for a vehicle in which a hybrid CVT transmission can be implemented by adding a hybrid motor inside the 4-speed transmission.

일반적으로 자동변속기는 복수의 유성기어세트 조합에 의해 구현되며, 토크 컨버터로부터 전달되는 회전동력을 다단으로 자동 변속하여 출력축에 전달하는 기능을 한다.Generally, an automatic transmission is implemented by a combination of a plurality of planetary gear sets, and functions to transmit rotational power transmitted from a torque converter to a multi-stage automatic transmission and transmit it to an output shaft.

자동변속기는 구현 가능한 변속단이 많을수록 보다 적절한 변속비의 설계가 가능할 뿐만 아니라, 동력성능 및 연비 면에서 우수한 차량을 구현할 수 있기 때문에, 보다 많은 변속단을 구현할 수 있도록 꾸준한 연구가 이루어지고 있다.The automatic transmissions have been designed to realize more efficient transmission speeds as more transmission speeds can be implemented, as well as to provide vehicles with superior power performance and fuel economy.

자동변속기는 동일 변속단을 구현하더라도 회전요소(선기어, 유성캐리어, 링기어)의 연결구성에 따라 상이한 작동 매커니즘을 갖는다.The automatic transmission has different operating mechanisms depending on the connection configuration of the rotating elements (sun gear, planetary carrier, ring gear) even when the same transmission speed is implemented.

한편, 자동변속기는 다수의 변속단을 구현하되, 변속제어 관점에서 이웃하는 변속단으로의 순차 변속시, 하나의 마찰부재를 해제하고 다른 하나의 마찰부재를 작동하는 작동조건을 만족시켜야 한다.On the other hand, the automatic transmission has to realize a plurality of speed change stages, in order to release one friction member and to operate the other friction member in a sequential shift from a shift control viewpoint to a neighboring speed change stage.
