Document Type and Number:
WIPO Patent Application WO/2021/176788
Kind Code:
A1
Abstract:
In the present invention, a first gear mechanism is connected to an input shaft. A first output gear is connected to the first gear mechanism. A second gear mechanism is connected to the input shaft. A second output gear is connected to the second gear mechanism. A motor is connected to the first gear mechanism and to the second gear mechanism. The motor continuously changes the speed ratio of the first output gear to the input shaft, and the speed ratio of the second output gear to the input shaft. A planetary gear mechanism includes: a first rotary element; a second rotary element; and a third rotary element. The planetary gear mechanism is capable of rotating about a first transfer shaft. A first driven gear is capable of rotating about a second transfer shaft. The first output gear is connected to the first rotary element. The second output gear is connected to the second rotary element via the first driven gear. The output shaft is connected to the third rotary element.
