Abstract
A planetary gear set includes a ring gear having an inner diametric surface that defines an inner ring gear portion. A carrier assembly is arranged within the inner ring gear portion. The carrier assembly includes a carrier member having a carrier member body including a planet gear support surface and at least one carrier plate support member that extends substantially perpendicularly from the planet gear support surface. The at least one carrier plate support member includes a carrier plate support element having an opening. At least one planet gear pin extends from a first end portion arranged at the planet gear support surface to a second end portion, and at least one anti-rotation pin extends from a first end section arranged at the planet gear support surface through the opening in the carrier plate support element to a second end section.
