Abstract
A device includes: a first planetary gear mechanism including a first sun gear connected to an input shaft, a first carrier connected to an output shaft, and a first ring gear; and a second planetary gear mechanism including a second sun gear connected to the input shaft, a second carrier connected to a first fixed element via a first engagement element, and a second ring gear connected to a second fixed element via a second engagement element, the first planetary gear mechanism and the second planetary gear mechanism are connected by the first ring gear and the second carrier, and the first sun gear and the first ring gear are connected by a third engagement element.
Claims14
A device comprising:
- a first planetary gear mechanism including a first sun gear connected to an input shaft, a first carrier connected to an output shaft, and a first ring gear;
- a second planetary gear mechanism including a second sun gear connected to the input shaft, a second carrier connected to a first fixed element via a first engagement element, and a second ring gear connected to a second fixed element via a second engagement element;
- and
- a third engagement element connecting the input shaft and the second carrier, wherein
- the first ring gear is connected to the second carrier so as to be integrally rotatable therewith,
- the third engagement element is provided between the first sun gear and the first ring gear, and
- the first planetary gear mechanism is disposed between a rotation electrical machine and the second planetary gear mechanism in an axial direction of the input shaft.
