Abstract
It is an object to provide an axle driving device that can change a deceleration ratio while obtaining a high deceleration ratio, and reduces noise during operation to have high ease of assembly and coolability. A carrier of a planet gear mechanism includes a first plate-like member, a second plate-like member, and a third plate-like member, and the third plate-like member includes the plate-like portion and the second plate-like member, a plurality of stays extended from the plate-like portion and connected to the first plate-like member, and a plurality of stays extended from the plate-like portion and connected to the second plate-like member.
Claims5
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
- a carrier of the planet gear mechanism includes a first plate-like member, a second plate-like member, and a third plate-like member that connects the first plate-like member and the second plate-like member, and
- the third plate-like member includes
- a base plate orthogonal to a rotary shaft of the carrier and located between the first plate-like member and the second plate-like member,
- a plurality of stays extended from the base plate and connected to the first plate-like member, and
- a plurality of stays extended from the base plate and connected to the second plate-like member.
A method for assembling an axle driving device in which
- a carrier of a planet gear mechanism includes a first plate-like member, a second plate-like member, and a third plate-like member that connects the first plate-like member and the second plate-like member, and
- the third plate-like member is orthogonal to a rotary shaft of the carrier and located between the first plate-like member and the second plate-like member, and includes
- an annular part provided in an annular shape about the rotary shaft, and
- a plurality of extensions extended from the annular part to the outside and arranged at equal intervals in a circumferential direction about the rotary shaft,
- the method comprising the steps of:
- attaching a first stepped gear between the extensions, with a smaller gear of the first stepped gear facing the first plate-like member;
- attaching a first planetary gear between the first plate-like member and the third plate-like member while causing the first planetary gear to mesh with a larger gear of the first stepped gear;
- attaching a second stepped gear between the extensions while causing a smaller gear of the second stepped gear to mesh with a larger gear of the first stepped gear;
- and
- attaching a second planetary gear between the second plate-like member and the third plate-like member while causing a second planetary gear to mesh with a smaller gear of the first stepped gear.
