Abstract | The present invention relates to a transmission for a hybrid vehicle, achieving multi-speeds in an electric vehicle (EV)/hybrid electric vehicle (HEV) drive mode to increase shifting efficiency and improving fuel efficiency and capable of allowing drive in a series mode and in a parallel mode. According to the present invention, the transmission for a hybrid electric vehicle comprises: an input shaft connected to an engine; an output shaft arranged in parallel with respect to the input shaft; a first hollow shaft installed on the outer circumferential surface of one side of the input shaft; a second hollow shaft installed on the outer circumferential surface of the other side of the input shaft; a first motor connected to the first hollow shaft; a second motor connected to the second hollow shaft; a first transmission output part arranged between the first hollow shaft and the output shaft; a second transmission output part arranged between the second hollow shaft and the output shaft; a first synchronizer synchronously connecting the first hollow shaft to the first transmission output part; and a second synchronizer synchronously connecting the second hollow shaft to the second transmission output part.
본 발명은 EV/HEV 구동모드 시의 변속다단화를 구현하여 변속효율을 증대시킴과 더불어, 연비를 향상시킬 수 있으며, 직렬 및 병렬모드의 구동이 가능한 하이브리드 차량용 변속장치에 관한 것이다. 본 발명에 의한 하이브리드 차량용 변속장치는, 엔진에 연결된 입력축; 상기 입력축에 대해 평행하게 배치된 출력축; 상기 입력축의 일측 외주면에 설치된 제1중공축; 상기 입력축의 타측 외주면에 설치된 제2중공축; 상기 제1중공축에 연결되는 제1모터; 상기 제2중공축에 연결되는 제2모터; 상기 제1중공축과 출력축 사이에 배치된 제1변속출력부; 상기 제2중공축과 출력축 사이에 배치된 제2변속출력부; 상기 제1중공축을 상기 제1변속출력부에 동기적으로 연결하는 제1싱크로나이저; 및 상기 제2중공축을 상기 제2변속출력부에 동기적으로 연결하는 제2싱크로나이저;를 포함하는 것을 특징으로 한다. |
