Abstract
The power distribution device includes: a double pinion first planetary gear mechanism including a first sun gear, a first carrier, and a first ring gear; and a double pinion second planetary gear mechanism including a second sun gear, a second carrier, and a second ring gear. The first sun gear and the second carrier are connected to each other and connected to a first motor, and the first carrier and the second sun gear are connected to each other and connected to a second motor. The first ring gear and the second ring gear are respectively connected to a right output shaft and a left output shaft, and a gear ratio of the first ring gear to the first sun gear and a gear ratio of the second ring gear to the second sun gear are set to the same value.
Claims4
A power distribution device for distributing power to two rotation shafts capable of performing mutually differential rotation, the power distribution device comprising:
- a first planetary gear mechanism comprising a first sun gear, a first carrier supporting a double pinion planetary gear, and a first ring gear;
- a second planetary gear mechanism arranged in parallel to and coaxially with the first planetary gear mechanism and comprising a second sun gear, a second carrier supporting a double pinion planetary gear, and a second ring gear;
- and
- a first rotating machine and a second rotating machine, wherein
- the first sun gear and the second carrier are connected to each other and are connected to the first rotating machine,
- the first carrier and the second sun gear are connected to each other and are connected to the second rotating machine,
- the first ring gear is connected to one of the two rotation shafts and the second ring gear is connected to the other of the two rotation shafts, and
- a gear ratio of the first ring gear to the first sun gear and a gear ratio of the second ring gear to the second sun gear are set to values equal to each other.
