Document Type and Number:
WIPO Patent Application WO/2019/074118
Kind Code:
A1
Abstract:
A speed reduction device (3) that reduces the speed of rotation of a rotary electric machine (2) and a differential gear device (4) that distributes a drive force from the rotary electric machine (2) between a first wheel and a second wheel are arranged coaxially with the rotary electric machine (2). The speed reduction device (3) includes a first planet gear mechanism (31) and a second planet gear mechanism (32). In the order of a power-transmitting path, the first planet gear mechanism (31) is arranged more toward the rotary electric machine (2) than the second planet gear mechanism (32). The reduction ratio of the first planet gear mechanism (31) is smaller than the reduction ratio of the second planet gear mechanism (32).
