Abstract
To provide a variable axle driving device which can obtain a high deceleration ratio, and which can prevent noise from being easily generated. Provided is an axle driving device which includes a planet gear mechanism. The planet gear mechanism includes first planetary gears, second planetary gears, first stepped gears, and second stepped gears. A driving force is input into a larger gear of each first stepped gear. A smaller gear of each first stepped gear is meshed with a larger gear of each second stepped gear. A smaller gear of each second stepped gear is connected to a first internal gear via the first planetary gear. A larger gear of each second stepped gear is connected to a second internal gear via a second planetary gear.
Claims8
An axle driving device comprising a planet gear mechanism configured to transmit a driving force to a first axle and a second axle via a differential mechanism, wherein
- the planet gear mechanism includes a first planetary gear, a second planetary gear, a first stepped gear, and a second stepped gear, each of the first stepped gear and the second stepped gear being formed of a planetary gear where a larger gear and a smaller gear are integrally provided,
- a driving force is input into the larger gear of the first stepped gear,
- the smaller gear of the first stepped gear is meshed with the larger gear of the second stepped gear,
- the smaller gear of the second stepped gear is connected to a first internal gear via the first planetary gear, and
- the larger gear of the second stepped gear is connected to a second internal gear via the second planetary gear.
