Abstract
An in-wheel drive device includes: a wheel bearing including a hub; and a speed reducer at least partially disposed in an internal space of the wheel bearing. The speed reducer includes: planet gears; a ring gear configured to engage the planet gears; and a carrier coupled to the planet gears and configured to transmit, to an outside of the in-wheel drive device, power generated by a revolution of the plurality of planet gears. A first sealing part is disposed in a region in which the carrier and the wheel bearing face each other.
Claims18
An in-wheel drive device, comprising:
- a wheel bearing comprising a hub;
- and
- a speed reducer at least partially disposed in a radially internal space of the wheel bearing, and comprising:
- planet gears;
- a ring gear configured to engage the planet gears;
- and
- a carrier coupled to the planet gears and configured to transmit, to an outside of the in-wheel drive device, power generated by a revolution of the plurality of planet gears,
- wherein a first sealing part is disposed in a region in which the carrier and the wheel bearing face each other,
- wherein the wheel bearing further comprises an outer race disposed outward, in a radial direction of the in-wheel drive device from the hub,
- wherein the first sealing part is disposed in a region in which the carrier and the outer race face each other, and
- wherein a groove portion having a recessed shape is disposed in an area of the outer race that faces the carrier, and the first sealing part is disposed in the groove portion.
