Dependent claims

An in-wheel driving device comprising:

a driving motor including a motor shaft;
a reducer configured to interwork with the driving motor to reduce a rotational force of the driving motor;
a reducer housing, in which the reducer is disposed;
a first gear connected to the reducer;
and
a support bearing part configured to support the reducer on an outer side of the reducer,
wherein the reducer includes:
a sun gear connected to the motor shaft;
a ring gear disposed in the reducer housing;
a planetary gear disposed between the sun gear and the ring gear and engaged with the sun gear and the ring gear;
and
a carrier, in which the sun gear is disposed in an interior thereof, configured to support the planetary gear and to rotate in conjunction with rotation of the planetary gear,
wherein the first gear is connected to an outer side of the carrier, and
wherein the support bearing part is disposed between the reducer housing and the carrier, and is mounted on one end and an opposite end of the carrier in an axial direction of the carrier.

A method for assembling an in-wheel driving device, the method comprising:

a sun gear assembling operation of inserting a sun gear into an interior space of a carrier through a gear seating recess formed in a planetary gear coupling part of the carrier;
a planetary gear assembling operation of disposing a planetary gear such that the planetary gear is seated in the gear seating recess and is enmeshed with the sun gear and coupling the planetary gear to the planetary gear coupling part;
a first gear assembling operation of assembling a first gear in the carrier such that the first gear rotates together with the carrier when the carrier rotates;
a support bearing part assembling operation of assembling a first bearing and a second bearing in the carrier such that the first bearing is disposed on one side of the planetary gear and the second bearing is disposed on an opposite side of the first gear;
and
a housing assembling operation of mounting a reducer assembly, in which the sun gear, the planetary gear, the carrier, the first gear, the first bearing, and the second bearing are assembled, in an interior of the reducer housing.
