Abstract
Systems and methods for reducing or eliminating backlash to control gear rattle include a planetary gear set with a planet carrier including a first part that supports at least one forward-torque carrying planet gear that has at least one tooth contacting a drive side of gear teeth of an associated sun gear and ring gear and a second part that supports at least one reverse-torque carrying gear that has at least one tooth contacting a coast side of gear teeth of the associated sun gear and ring gear, the second part of the carrier being rotationally biased relative to the first part to reduce or eliminate effective backlash of the gear set.
