Abstract
A transmission assembly includes a sun gear including an outer set of gear teeth, a planet carrier disposed around the sun gear, and a ring gear surrounding the planet carrier and the sun gear and including an inner set of gear teeth. At least one double planet is attached to the planet carrier. The double planet includes a first set of gear teeth and a second set of gear teeth, the outer set of gear teeth of the sun gear meshes with the first set of gear teeth, and the second set of gear teeth meshes with the inner set of gear teeth of the ring gear.

A transmission assembly comprising:
- a sun gear including an outer set of gear teeth,
- a planet carrier disposed around the sun gear,
- a ring gear surrounding the planet carrier and the sun gear and including an inner set of gear teeth, and
- at least one double planet attached to the planet carrier,
- wherein the double planet includes a first set of gear teeth and a second set of gear teeth,
- wherein the outer set of gear teeth of the sun gear meshes with the first set of gear teeth,
- wherein the second set of gear teeth meshes with the inner set of gear teeth of the ring gear, and
- the transmission assembly further comprises two bearing assemblies rotatably supporting the sun gear with respect to the planet carrier, each bearing assembly being disposed on a separate axial side of the sun gear.
A transmission assembly comprising:
- a sun gear including an outer set of gear teeth,
- a planet carrier disposed around the sun gear and including at least one hub,
- a ring gear surrounding the planet carrier and the sun gear and including an inner set of gear teeth,
- at least one double planet disposed on the hub of the planet carrier, and
- at least one support member disposed on the hub of the planet carrier, and
- wherein the double planet includes a first set of gear teeth and a second set of gear teeth,
- wherein the outer set of gear teeth of the sun gear meshes with the first set of gear teeth,
- wherein the second set of gear teeth meshes with the inner set of gear teeth of the ring gear, and
- wherein the transmission further comprises an inner bearing assembly supporting the sun gear with respect to the planet carrier and having an outer ring coupled with the support member and an outer bearing assembly supporting the planet carrier with respect to the ring gear and including an inner ring disposed about the support member.
A transmission assembly comprising:
- a sun gear including an outer set of gear teeth,
- a planet carrier disposed around the sun gear,
- a ring gear surrounding the planet carrier and the sun gear and including an inner set of gear teeth, and
- at least one double planet attached to the planet carrier,
- wherein the double planet includes a first set of gear teeth and a second set of gear teeth,
- wherein the outer set of gear teeth of the sun gear meshes with the first set of gear teeth,
