Abstract:
1. A power transmitting device for a hybrid vehicle having an internal combustion engine and an electric motor, the power transmitting device comprising: an internal combustion engine output shaft to which motive power is input from the internal combustion engine; a first main input shaft, which is disposed parallel to the internal combustion engine output shaft and selectively connected to the internal combustion engine output shaft by a main make-and-break device; a first sub input shaft, which is disposed coaxially with the first main input shaft and selectively connected to the first main input shaft by a first make-and-break device; a second sub input shaft, which is disposed coaxially with the first main input shaft and selectively connected to the first main input shaft by a second make-and-break device; an output shaft, which is disposed parallel to the first main input shaft and connected to the first sub input shaft and the second sub input shaft, in each case via a respective pair of gears sharing no common gear with each other, and outputs motive power to a driven unit via a counter shaft; and a deceleration mechanism configured so as to be capable of rotating a first rotating element, a second rotating element, and a third rotating element differentially with respect to one another, wherein: the first sub input shaft and the second sub input shaft are arranged in series along an axial direction of the first main input shaft, and each of the first sub input shaft and the second sub input shaft coaxially encloses the first main input shaft circumferentially; the first rotating element is connected to the first main input shaft and the electric motor; the second rotating element is connected to the first sub input shaft; the third rotating element is connected to a lock mechanism, which is capable of locking the third rotating element to an immovable part; and the second rotating element decelerates motive power transmitted from the first rotating element and motive power transmitted from the third rotating element and transmits the motive powers to the output shaft via the first sub input shaft.
